Diode laser for Percutaneous Laser Disc Decompresion (PLDD)

The Diode laser is indicated for Percutaneous Laser Disc Decompresion (PLDD), for treatment of back pain resulting from herniated discs.
The treatment principle of PLDD is based on the concept of the intervertebral disk being a closed hydraulic system. This system consists of the nucleus pulposus, containing a large amount of water, surrounded by the inelastic annulus fibrosus. An increase in water content of the nucleus pulposus leads to a disproportional increase of intradiskal pressure. A reduction of intradiskal pressure causes the herniated disk material to recede toward the center of the disk, thus leading to reduction of nerve root compression and relief of radicular pain. In PLDD, this mechanism is exploited by application of laser energy to evaporate water in the nucleus pulposus.
Laser energy is delivered by a laser fiber through a hollow needle placed into the nucleus pulposus. The needle is placed into the intervertebral disk under local anesthesia. Apart from evaporation of water, the increase in temperature also causes protein denaturation and subsequent renaturation. This causes a structural change of the nucleus pulposus, limiting its capability to attract water andtherefore leading to a permanent reduction of intradiskal pressure.

Laser VS other therapy modalities

COMPARISON THERAPY MODALITIES

Comparison to Pharmaceutical Relaxants
This form of therapy works via the entire nervous system and is indicated in cases of entire body muscle seizure as in a traumatic accident or shock;however, depressing the horse’s entire nervous system is contraindicated in addressing specific muscle problems. Drug therapy can relax a general muscle mass, but since it affects the contraction as well as the release processes of the muscles, it diminishes the horse’s overall strength and capability.Though necessary in cases following acute trauma, as a treatment modality in chronic situations, it is often ineffective.
Comparison to Electrical Stimulation
Electrical Stimulation devices work by adding contraction to a muscle that already cannot find release. This may not be the best way to release muscle spasms. These devices can be useful for low levels of pain relief, for neuromuscular diagnosis, and for exercising a muscle with deficient nerve impulse
(nerve damage).
Comparison to Thermotherapy & Heat
Applied to a wide area, heat application is not accurate and is carried away by the bloodstream. It has neither depth nor durability and cannot affect deep tissue. The best use for this therapy is to relax a general area which affects the nerve endings and may bring some temporary comfort to a horse.
Comparison to Cold Hydrotherapy & Cryotherapy
Because the body always tries to maintain a steady body temperature, icing an area will actually produce increased circulation after several minutes of initial vasoconstriction. After acute trauma, it is the treatment of choice to stop hemorrhaging, reduce pain and keep swelling to a minimum. After this initial physiological function, other modalities are more efficient and effective in treatment.
Comparison to Magnetic Therapy
Studies show that the magnetic field produced by even the strongest magnet cannot and does not penetrate more than a fraction of an inch below the skin layer, making them ineffectual against deep muscle problems.
Rest
Rest is extremely important after acute injury; however, there are times when it becomes counterproductive. This is because resting and immobilization allow a spasm to become permanent. Muscle strength diminishes significantly after two weeks of stall rest and joints become stiff from lack of movement.In addition, confinement can be mentally taxing on a horse, resulting in spasms due to tension and stress.
Equine Chiropractic Treatments
High Velocity Thrust (HVT) deals with subluxations of the skeletal structure and facilitating normal space between joints, therefore enhancing joint function. Much benefit in the way of relieving pressure on the nerves, can be derived from chiropractic adjustments, when the situation calls for it.Though the muscles may derive some relief when treated by this method, equine chiropractic cannot relieve muscle spasms or knotted fascia and is not the best treatment for such situations. In addition, HVT has proven to cause muscle and fascial tearing, which may cause soreness and inflammation in a horse. This is why the technique must be done by a fully trained and experienced practitioner and why several states, will only allow licensed veterinarians to perform Equine Chiropractic.
Muscles have two primary jobs; either to hold bones together (static) or move them (dynamic). If a vertebral or joint misalignment has existed for anylength of time, the muscles will have memorized an “incorrect” setting. After chiropractic adjustment, these muscles do not automatically “right”themselves. Unless the muscles involved are released so that “correct” muscle memory can be reestablished, chiropractic adjustment will usually not hold. Hypertonic muscles will simply pull the horse out of alignment again.

Clinical Benefits of Veterinary Diode Laser Surgery

Clinical Benefits of Veterinary Diode Laser Surgery

Reduced Pain: The Diode Laser seals nerve endings as it cuts through tissue; this reduces the amount of pain the patient feels during and after surgery.

Reduced Bleeding: The Diode Laser cauterizes and seals small blood vessels as it cuts; this laser energy achieves hemostasis and provides the surgeon with a bloodless surgical field in most procedures.

Reduced Swelling: Diode laser surgery is minimally invasive, eliminating the tearing and bruising of tissue associated with traditional surgical methods; lymphatic vessels are also sealed.

Reduced Infection: Diode Laser energy acts as an antibacterial agent by producing high temperatures, effectively eliminating microorganisms.

Quicker Recovery: Laser surgery provides much quicker recovery times by reducing swelling, lessening the chance of infection, reducing pain, and preventing blood loss.

How varicose veins form and how laser treatment performed

How varicose veins form and how laser treatment performed



Endovenous Laser Ablation (EVLA), also sometimes marketed as Endovenous Laser Therapy™ (EVLT) is a minimally invasive method of treating varicose veins. It uses a laser which is inserted into the vein, guided by ultrasound scanning, under local anaesthetic to deliver heat energy which causes the vein to contract and seal itself shut.

EVLA is used to treat an underlying venous reflux problem in veins higher up and deeper in the leg which are contributing to the presence of varicose and thread veins rather than treating the veins themselves. It is a ‘walk-in, walk out’ procedure so you will be able to leave the clinic after treatment.

VELAS Pro for Vaginoplasty


VELAS Pro for Vaginoplasty

The vaginoplasty operation usually takes about 1 - 2 hours, and is treated as a day case, meaning that you are discharged to go home a few hours after your surgery is completed. There may be cases where an overnight stay is required.



The surgery is designed to tighten the vagina and is done by joining together the stretched muscle at the back of the vagina and therefore shortening it, using dissolvable stitches, and then removing excess vaginal lining (vaginal mucosa) and tightening the surrounding soft tissues. This procedure may also be done using a laser. The resulting decrease in the size of the vaginal cavity creates more friction during sexual intercourse, often described as giving a woman back the vagina she had before she had children.

Lasers for Thread Veins or Spider Veins

Lasers for Thread Veins or Spider Veins 
A laser is a high energy beam of light that can precisely transfer this energy into certain tissues within the skin. These beams of light are produced in one wavelength or colour at a time, and can vary in terms of their strength and the type of tissue that they can target.



Lasers used on a variety of veins or pigmented (discoloured) skin problems can direct their heat towards a desired target in the skin which results in “damage” to particular tissues. For example, in the case of thread (spider or red) veins, the target is the blood filled vessel that is precisely heated and destroyed by the laser without harming surrounding areas.

Diode Laser for otolaryngology

Diode Laser for otolaryngology

This a lightweight, portable, battery supported ,980-nm wavelength Diode laser with a fiber optic delivery system is being used widely the field of otolaryngology, as it is less expensive.

The laser transmits radiation via a flexible quartz fiber optic cable that can be used with a set of intra nasal, micro laryngeal hand pieces. These hand pieces allow for optimal laser focusing.

Light at its particular wavelength is absorbed by tissues relatively independent of tissue type. Tissue response at this wavelength is determined by the absorption of water as well as by absorption of endogenous components such as hemoglobin and melanin. As a result, the diode laser has a large (up to 10 mm) penetration depth in biologic tissue, which makes it ideal for photo coagulation. By contrast, the Co2 laser has a very shallow penetration depth and thus is best used for tissue vaporization.

This laser compares favorably with several of the other thermal lasers used in otolaryngology; its tissue-cutting and coagulation effect is comparable to that of other commonly used lasers.

The Diode laser’s flexible fiber delivery system is compatible with hollow instruments, allows for coaxial vision, and is ideally suited for intranasal, oral and micro laryngeal use.

The Diode laser is housed in a portable case and light weight so it can be easily transported between the OPD and the operating room. The length of set-up time is generally less than 5 minutes, and no warm-up period is necessary. It is battery supported in case of power failure.

Economic Merit for veterinary laser

Economic Merit for veterinary laser

Effective use of capital funds is a primary concern of most veterinarians. Medical equipment has to be both clinically effective and contribute to the bottom line. Where laser surgery is concerned, it may be difficult to realize how this capital expense can have a positive impact on revenue. With laser technology, veterinarians have the opportunity to optimize revenue, while gaining a marketplace advantage by offering a “higher standard of care”.

Lasers in medicine for humans is well known and accepted as the best alternative for many procedures. Low blood loss, reduced pain, reduced infection and rapid recovery are important to pet owners as well. Today the public is educated on the benefits of laser surgery and often demand the same standards of care for their animals. A laser in the clinic is an important tool for veterinarians who understand the value of offering a choice for clients. It’s a win-win; the client receives the best care for their loved one while the practice gets to charge a premium fee for premium service. The actual per procedure charge can quickly amortize the cost of the laser. The recurring per procedure cost is low, giving the practice a good operating margin while using a “best solution” for the client. GIGAA VET laser system offers veterinarians the opportunity to use their surgical skills while complying with the pet owner’s desire for a good clinical results.

Laser for gynecology

Laser for genecology

During the last decade, the use of laser technology has become more common in operative gynaecology in Norway. The first modality to be introduced was the carbondioxide, CO2-laser, used together with the colposcope for the treatment of cervical intraepithelial dysplasia and condylomata. The same laser has also been employed through laparoscopic technique, with the aid of modern microvideofacilities. Finally, using the hysteroscopic technique, the diode laser, has been introduced for treating intrauterine conditions. The use of laser in operative gynaecology makes it necessary to change the attitude towards indications for operation. The possibilities are challenging, and the effect on the length of postoperative convalescence is especially rewarding. The introduction of lasers in gynaecology could have far-reaching consequences for efficient use of hospital resources.

USE of Diode Laser for veterinary surgery

USE of Diode Laser for veterinary surgery
With the diode laser, energy is transferred from the housing to the tissue by a solid fiber-optic system. Fibers vary in size, typically 400 mm to 800 mm, Orr says.

“An advantage to this type of system is the ability to deliver laser energy to tissue through ports in fiber-optical devices and in aqueous environments,” Orr says. “I use my diode laser in just about all my declaws. I don’t need to use a tourniquet; there is no bleeding and healing is fast. I use a little skin glue to close and that’s it.”

You can get thousands of hours of use with a diode laser before worrying about needing an upgrade or replacement, It is lightweight and has a fine tip like a scalpel. The great thing about a diode laser is that it isn’t something you have to spend money on without getting a return, like an autoclave. You can expect to make a direct profit from a laser.

VELAS Lipolysis Laser

VELAS lipolysis is a safe, effective, minimally invasive procedure that uses a laser to liquefy and remove unwanted fat in targeted body zones. In addition to removing unwanted fat, Lipotherme’s thermal effect causes the skin to contract, resulting in firmer, smoother skin that further enhances your body shaping goals.
Faster - Reduced procedure time means less time in the doctor’s office
Minimally invasive - Least invasive of all lipolysis procedures
Minimal Healing - Advanced technology means you’ll be back in action in less time
Minimal Discomfort - Patented technology allows you to remain awake during the procedure



Laser DCR Surgery

Laser DCR is a simple and extremely short procedure taking only a few minutes for completion- on an average 5 to 10 minutes. There is no visible scar as no skin incision is required for the procedure. Laser DCR is associated with virtually no pain or bleeding as it is a minimally invasive procedure with the least trauma to the tissues. It needs no anesthesia (injection) and can be performed with anaesthetic drops itself. Laser DCR is also a much safer treatment option especially for the aged as it can be performed as an outpatient surgery and generates minimal intra and post surgical morbidity. This procedure is also associated with a lower recurrence rate.


MEDICAL THERAPY AT HIGH-EMITTING POWER

MEDICAL THERAPY AT HIGH-EMITTING POWER

Class IV High Power Laser Therapy (HPLT) is able to treat all the same conditions that respond well to Cold Laser Therapy including a great many more. Because High Power Lasers are able to penetrate more deeply into body tissues the vast majority of muscles, ligaments, tendons, joints, and nerves and skin can be treated effectively. Treatment times are also dramatically reduced when treating with High Power Laser Therapy. Low Power Lasers (25-500mW) would often require 60-120 minutes in order to deliver a Therapeutic Dose to the affected body part. High Power Laser Therapy (500mW – 7,500mW) deliver an equivalent Therapeutic Dose in a fraction of the time. In fact, the Avicenna High Power Laser (the Avicenna Laser, the most powerful therapeutic laser ever developed, operates at 7,500mW) can deliver a Therapeutic Dose of laser energy to many injured parts of the body within 5-15 minutes!

In summary, High Power Laser Therapy can Treat Many More Conditions in Much Less Time with Far Better Results than Cold Laser.

Use of Diode Laser in ENT Surgery

Use of Diode Laser in ENT Surgery

ENT Surgeons use different types of lasers like Co2, KTP, Nd.YAG and Diode Laser in their practice.
Diode Laser
This a lightweight, portable, battery supported ,980-nm wavelength Diode laser with a fiber optic delivery system is being used widely the field of otolaryngology, as it is less expensive.
The laser transmits radiation via a flexible quartz fiber optic cable that can be used with a set of intra nasal, micro laryngeal hand pieces. These hand pieces allow for optimal laser focusing.

Application techniques
1. It can be used in contact mode, in which the tip of the fiber is placed directly on the surface of the tissue. This mode is effective for both photocoagulation and vaporization of tissue, depending on the power density. At the low- or mid-power range, coagulation occurs; at a higher level, vaporization occurs.
2. The laser can be used in near-contact mode, in which the tip of the fiber remains several millimeters apart from the tissue. This mode is largely used for tissue photo coagulation.
3. The laser can be used for interstitial laser-induced thermotherapy, a minimally invasive method of treating both benign and malignant tumors. The laser is placed through puncture holes in the skin, and its energy is absorbed by local tissues. This hyperthermic state causes either immediate or delayed tissue necrosis via coagulation.
4. In the clinic most cases can be done after administering a topical anesthetic and a decongestant spray to the nasal cavity, but micro laryngeal surgery needs General anesthesia with special fleximetalic tube to prevent fire hazard.

Use of Diode Laser in ENT Surgery
Turbinate reduction in case of allergic Rhinitis and Vasomotor Rhinitis
Cautery for Epistaxis, Telengiactasia, Osler-Weber-Rendu disease etc
Oral lesions- Leukoplakia , Erythroplakia
Releasing sub mucous fibrosis
Laser Cautery Tongue lesion
Tonsillotomy for Tonsillolith
Laser Granular pharynx
Myringotomy
LAUP-Snoring and OSA surgery
Microlaryngoscopy and removal of nodules, polyp etc under GA.
DCR with eye surgeons.
Conclusion
• Its portability and functional diversity make it an attractive alternative to the other laser machines like Co2 and KTP.
• Most cases can be done under LA in the OPD set up
• Very cost effective if other departments like, Dental and Ophthalmology share the equipment

Group Of Lasers For Dental Low Level Laser Therapy

LASER DENTISTRY/LOW LEVEL LASER THERAPY: Therapeutic lasers expand the scope of dentistry
This group of lasers includes:
  • The helium-neon (HeNe) laser was the first commercially offered dental laser in the 1980s. A gas laser with a main wavelength of 632.8 nm, it had the disadvantage of low output (1-2 mW) and brittle fiber optics with high power loss. HeNe lasers are now available with power of up to 60 mW, much more durable fiber, and improved transmittance. Although comparatively low-powered, HeNe light has the advantage of a long length of coherence.
  • The HeNe laser has largely been replaced by technically less sophisticated and consequently less expensive InGaAlP lasers, which work at wavelengths of 633 - 690 nm and offer power of several hundred milliwatts. Being diode-based, the length of coherence is much shorter and the fluence used in successful HeNe studies has to be at least doubled with the red diodes to obtain similar results.
  • GaAlAs lasers now dominate the market, probably because inexpensive diodes at these wavelengths have been available for a long time. The most common wavelength, 808 nm, has the best optical penetration into tissue. GaAlAs lasers can provide output in the watt range, though typical outputs are 100 - 500 mW.
  • The GaAs laser is a pulsed laser, emitting at 904 nm, that requires lower dosages than other wavelengths. This laser has relatively complicated electronics–which may be the reason not many manufacturers offer them. Typical output is 10 - 100 mW.
