Four characteristics of laser


 Along a straight line rather than divergence
-High brightness
 In the high concentration of space and time, it can get very high energy from the unit area and time.
-High security
 The spectral width is very narrow and the color is very pure. It is divided into infrared light and ultraviolet which is called common light.
-High coherence
 The same frequency, and the vibration direction of the same two wave has a phase constant encounter department. Laser can  maintain a constant phase difference time.


●Gas laser:  The common is CO2, He-Ne laser,Ar + (Er).
●Solid-state laser: ruby laser, neodymium glass laser, Nd and YAG laser.
●Liquid laser: organic dye laser.
●Semiconductor laser: gallium arsenide semiconductor laser, diode.

Indonesia, Malaysia, the Philippines, and Thailand

For expert assistance with medical device registration in Asia, rely on Pacific Bridge Medical's (PBM's) medical device consultants.

The medical device markets in Indonesia, Malaysia, the Philippines, and Thailand are about $1.2 billion in total. Medical device registration in these countries varies.

While product registration is voluntary in Malaysia, in the other countries, a modest amount of paperwork needs to be submitted. If your medical device has Western approval, things will often be easier.

Understanding the Common Submission Dossier Template

The Association of Southeast Asian Nations (ASEAN) is implementing a plan to harmonize medical device regulations called the ASEAN Medical Device Directive (AMDD).

The AMDD lays out basic requirements for medical device safety and performance, the medical device classification system, a Common Submission Dossier Template for medical devices (CSDT), and an ASEAN-wide postmarketing alert system. 

The CSDT sets out what data will be required in the single dossier usable for device registration in all ASEAN countries. The CSDT format will be used in all ten ASEAN countries by 2015, meaning that a dossier accepted by any ASEAN regulatory body can also be accepted in the same format by all other ASEAN regulatory authorities.

The other major document required for medical device approval is the Declaration of Conformity, which demonstrates the medical device's compliance with the ASEAN Essential Principles of Safety and Performance.

Diode laser vaporization prostatectomy is feasible and appears to be safe and effective for BPH.

The Prostate is an organ forming part of the male reproductive system. It is located immediately below the bladder and just in front of the bowel. Its main function is to produce fluid which protects and enriches sperm. In younger men the prostate is about the size of a walnut. It is doughnut shaped as it surrounds the beginning of the urethra, the tube that conveys urine from the bladder to the penis. The nerves that control erections surround the prostate.
Benign prostatic hyperplasia (also called BPH) is a condition that affects the prostate gland in men. The prostate is a gland found between the bladder (where urine is stored) and the urethra (the tube urine passes through). As men age, the prostate gland slowly grows bigger (or enlarges). As the prostate gets bigger, it may press on the urethra and cause the flow of urine to be slower and less forceful. "Benign" means the enlargement isn't caused by cancer or infection. "Hyperplasia" means enlargement.

What are the benefits of laser surgery?


#1. Less bleeding.
– Because the small blood vessels are sealed during surgery.

#2. Less pain.
– Because the nerves are sealed as well. Only minimal anesthesia is required. - Less swelling after surgery.
#3. Less swelling after surgery.
– Because the small vessels are sealed and post-operative reaction is minimal. - Quicker recovery from surgery.

#4. Quicker recovery from surgery.
– Because a patient pet experiences less bleeding and less pain. After all, pets can go home earlier.

Radiofrequency ablation and laser treatment
Probably. These are newer treatments for varicose veins. There hasn't been enough good research to say for certain how well they work in the longer term, but studies so far are promising.

What are they?
Surgery is the only way to get rid of varicose veins completely. But it's a big operation and there are risks. Surgeons have been looking at other ways to treat varicose veins that may be easier and quicker than traditional surgery. One of these ways is closing the vein with heat.

Your surgeon can use heat to close your varicose veins in several ways.

Radiofrequency ablation
In this method, your surgeon puts a thin instrument into your vein. The instrument produces energy, which heats and seals off your vein. This is called radiofrequency ablation. Surgeons usually use this method for larger varicose veins.

If you're having treatment for a varicose vein in your leg, your surgeon will:[1]

Give you a local anaesthetic to numb the area, so you'll be awake but you won't feel any pain
Make a small cut above or below your knee, depending on the area being treated
Put the heating device into your vein or thread it through a very thin tube (called a catheter) and then into your vein
Heat the device and pull it back slowly through your vein.
The heated device seals your vein while your surgeon pulls it out.

Laser treatment
In this method, doctors use a laser to seal off veins.

If you're having treatment for a varicose vein in your leg, your doctor will:

Give you a local anaesthetic to numb the area, so you'll be awake but you won't feel any pain
Thread a thin tube (called a catheter) through a small hole in your skin into your vein
Place a laser in the tube, so that the intense light from the laser heats your vein and makes it close up
Slowly remove the laser, sealing off your vein as the laser comes out.
Laser treatment is quick. It takes just 90 seconds to treat a 30-centimetre (12-inch) length of vein.[2]

The National Institute for Health and Clinical Excellence (NICE) is the government organisation that advises doctors about treatments. NICE says that both radiofrequency ablation and laser treatment are safe enough and work well enough for use in the NHS. But we don't know the long-term effects of these treatments. You should talk to your doctor about the risks and benefits of having one of these treatments.[2][3]

How can they help?
Radiofrequency ablation seems to work as well as having surgery to strip out varicose veins. A large summary of studies, called a systematic review, found that both treatments worked well in nearly everyone who had them.[4]

Radiofrequency ablation may be less painful than having veins stripped out by surgery. People also get back to normal more quickly after this treatment than people who have surgery.[4]

Laser treatment may also work as well as surgery, and cause less pain and bruising. People also get back to normal more quickly after this treatment than people who have surgery.[4][5][6][7][8]

But we don't know whether veins are more likely to come back after these treatments than after surgery. We need longer and bigger studies to tell.

Studies have found that radiofrequency ablation and laser treatment work about as well as each other, but that radiofrequency ablation may cause less pain and bruising.[9][10]

How do they work?
Usually veins carry blood upwards through your legs to your heart. They have one-way valves in them that keep blood flowing in the right direction.

In varicose veins, the valves don't work properly. So blood slips backwards into the vein, causing your vein to bulge. To learn more, see What are varicose veins?

Closing up your varicose vein with heat or lasers means blood can no longer flow through that vein, and it flows through your other veins instead. So blood no longer pools in your varicose veins, causing them to bulge.

Can they be harmful?
Radiofrequency ablation
Radiofrequency ablation does sometimes have side effects.

Between 6 in 100 to 7 in 100 people who have radiofrequency ablation get burns.[3] But as doctors get better at using this technique, burns should become less of a problem.

Some people get an unusual feeling in their legs after having radiofrequency ablation.[3]

About 2 in 100 to 3 in 100 people get inflammation in the vein.[3] Doctors call this phlebitis. If you have phlebitis, your veins can become swollen. They feel hard and warm, and look red. The area can feel sore.

More serious problems, such as having clots in your veins (deep vein thrombosis) or a blockage in your lungs (pulmonary embolism), happen in less than 1 in 100 people.[3]

Laser treatment
You're likely to get some pain and bruising after having laser treatment.[2] But this will go away after a few weeks. Some people also get inflammation after having laser treatment.[2] It's also possible to have loss of feeling, burns, and damage to other veins, although these problems aren't likely.

Compared with radiofrequency ablation, laser treatment might give you more pain and bruising in the first couple of weeks afterwards.[11] But there doesn't seem to be a differnce in the longer term.

Dental surgical instrument comparson

Several variants of dental laser are in use, with the most common being diode laserscarbon dioxide lasers, and yttrium aluminium garnet laser. Different lasers use different wavelengths and these mean they are better suited for different applications. For example, diode lasers in the 810–900 nm range are well absorbed by red colored tissues such as the gingivae increasingly being used in place of electrosurgery and standard surgery for soft tissue applications such as tissue contouring andgingivectomy

Dental laser:   Diode laser VS  Er:YAG laser
Er:YAG lasers typically emit light with a wavelength of 2940 nm.
the output of Er:YAG lasers is also absorbed by hydroxyapatite, which makes it a good laser for cutting bone as well as soft tissue.the output of an Er:YAG laser is strongly absorbed by water. This fact limits the use of this laser in surgery.Er:YAG lasers are far less common than their relatives diode laser.
Diode laser is portable in size,affordable,very good for soft tissue surgery,the limit is can not applied to hard tissue
