Biological Effects of Laser

Thermal effect: the irradiated tissue can elevate temperature, correct optical output port temperature is even a few hundred or thousands of degrees, use the organization to make the water boiling, increase pressure, and separate organization. At the same time, make the edge to have a coagulation or vaporization, so you can get a cutting, freezing, evaporation and other clinical results.

Photochemical effect: biological macromolecules absorb the laser photon energy and cause chemical reactions in vivo series, it can reduced the activity of enzymes, amino acids, proteins, nucleic acids, or have an effect on treatment and diagnosis.

EMF effect: in the form of electromagnetic fields play a role in biological tissue.
Pressure effect: radiation pressure, air recoil pressure, pressure within the gasification, thermally induced expansion of pressure, electrostrictive pressure and so on.

Stimulating effect: mainly in the weak laser, biology absorb photons, get energy, change and have biological reaction.

Dental Diode Lasers

Low level 808-980- These are for soft tissue procedures. The laser is absorbed by pigmented (tissue) areas. Common uses are tissue contouring, toughing for crown impressions. Others are gingivectomy, soft tissue crown lengthening, frenectomies, removal of redundant soft tissue and similar procedures. An apthous ulcer can be “lased” to reduce symptoms and promote healing.

HPLAS II 1470nm+980nm 200W Laser Urology for BPH

Clinical Application:

Laser urology for Benign Prostate Hyperplasia

Related Keywords:

Benign prostate enlargement, Transurethral resection of the prostate(TURP), Prostate ablation

Medical device:

HPLAS II 1470nm+980nm 200W

Accessories:

600um side-fire fiberHook Shot fiber

Introduction and Operation procedure:

The Dual 980nm+1470nm laser could enable the ejaculation in internal structures of theprostate spared, so it is the very first time for laser method to prevent the so-calledretrograde ejaculation, particularly for middle-aged men between 40 and 50 years old whomay still have the wish to have children even if they are suffering from BPH.

The excellent hemostatic profile has a positive impact on the healing process: there isvirtually no loss of blood during and after procedure, and the internal tissue is spared. Thepatient experiences relief following the treatment and no longer feels the constant anduncomfortable urge to urinate.

Course of treatment:

1. The treatment commences by inserting Cystoscope containing the fiber through the urethra.

2. The head of the fiber is pushed out of the probe.

3. The dual laser of 980nm and/or 1470nm is discharged from the probe head.

4. The operator steers the probe, rotating it to ablate the tissue in a circular motion.

5. The funnel grows larger step by step and the probe is completely withdrawn from theprostate at the end.

6. Urine can once again flow off freely.

Advantage:

1. 980-nm diode laser offers a higher tissue ablation capacity and similar haemostasiscompared with the KTP laser.

2. In comparison with TURP, both tissue ablation and bleeding are significantly reduced.

3. Short recovery with a laser treatment.

Notices:

1. There are many fibers used for BPH treatment, we will suggest side-fire fibers or HookShot fiber from German fibers partners.

2.  It is necessary to be trained before operating the surgery, GIGAA LASER will provideUrologist training in China or abroad.

980nm Ovarian Cystectomy Laser

Ovarian Cystectomy is any collection of fluid, surrounded by a very thin wall, within an ovary. Any ovarian follicle that is larger than about two centimeters is termed an ovarian cyst. Most ovarian cysts are functional in nature and harmless, and affect women of all ages. 

Some ovarian cysts cause problems, like bleeding and pain. If the cysts larger than 5cm in diameter that surgery must be required.

Related Keywords:

Medical device: 

Velas60w 980nm: Contact, 8~15w, CW

Accessories: 

600um optical fiber

Operation procedure:

1. After comprehensive local anesthesia, penetrate 600um fiber into the catheter.  And then put the catheter in to laparoscope that let the fiber out of the catheter about 1cm.

2. Setting the power 8-15w, start the laser, and control the fiber power experienced with foot switch.

3. After cyst puncture, used laser cut the cyst ovarian tissues surface, and peel out the cyst, cut down the base of cyst. Using 5-10w laser power (keep the laser tip with2-4mm distance with tissues) cautery the residual cyst wall and bleeding place.

4. 4 hours to 2 days the patients could leave out the hospital.

Advantage: 

1. Diode lasers 980nm have good effect on tissue coagulation and vaporization that makes the operation low power needed. The laser irradiations can hemostasis immediately at the same time of soft tissue cutting.

2. Because that the diode laser diathermy shallow, the clinical using is safe that can reduce the damage of the organs in depths.

3. The temperature of tissue surface can be reached 150℃, energy concentrated that make the soft tissue cutting faster.

4. Laser pilot beam make the cautery place exactly, it is easy to learn.

Notice:

1. Do not make the fiber tip bury into the tissues when you contact with the cyst tissue that may rupture the fiber.

2. The surgeon must be trained to control the power and clinical information experienced.

TREATMENT MANUAL VAPORIZATION OF BENIGN OR CANCEROUS PROSTATE

Clinical Application:
HPLAS diode laser for vaporization of benign or cancerous prostate treatment from
GIGAALASER

Clinic Explanation:
The aim of diode laser ablation is resect a channel which would allow or improve urine
flow, instead of removing maximal amount of prostate tissue.
The HPLAS 980nm highly absorption in water and hemoglobin. It provide good ablation
and coagulation effect.

Related Keywords:
Benign prostate, Transurethral resection of prostate, Urinary retention, diode lasers

Medical device:
HPLAS 980nm 150W
Mode: CW mode
Operation power: 90-125W

Accessories:

HPLAS from gigaalaser, Side fiber, Cystoscope

Operation procedure:
1. General or local anesthesia, before the procedure, the patient receive parenteral
antiemetic, antibiotic garamycine 240mg,diazepam 10mg and extended release
oxycodone 10mg.

2. Connecting the accessories, lock the fiber in the resectoscope mechanism system,
then opening the device and setting parameters. Out put power 90w-125w.

3. Press the foot switch and fiber movement move forward and backward to ablate the
prostate.

4. The procedure is about to terminate when is estimated prostatic fossa was already
wide enough, which would allow or improve urine flow. Lase the total energy ranged
from 78kj~142kj.



Advantage:
According to those data near-infrared wavelength of 980nm, with its distinctive position in
the middle of all important parameters seem to be most balanced and attractive.
1. Compare to Nd-yag
HPLAS 4 times higher absorption in water. Lower penetration depth, less risk.


2. Compare to KTP
Much better ablation with at least same coagulation
Cheaper both laser system and fiber

3. Compare to holmium laser
Diode:220v power supply, compact size,
Holiminu:expensive(morcelator and laser), difficult, time-consuming

4 Compare to traditional TRUP
No need perfusion, catheter tension, higher safety and comfort

Notice:
* Laser fiber needs very delicate handling and regular cleaning through tissue
brushing,not removing during the procedure,otherwise laser fiber breaks.
* Careful and limited ablation near colliculus is mandatory otherwise incontinence may
occur.


Illustration:
A - before beginning. B, C - during procedure(evaporation bubbles are visible)
D - at the end of the procedure,urine channel is created.

How Leg Vein Therapy Works

Leg Vein Therapy

It is estimated that over half of the female population is affected by noticeable red, purple or blue veins, also known as spider veins, 

in the upper and lower areas of the legs. Spider veins are a cosmetic problem that many women face, but few realize there is a treatment 

for the veins. The Aesthetics Gallery offers both sclerotherapy and laser treatments for leg veins. We will help you determine which is best 

for you.

How Leg Vein Therapy Works

Spider veins are caused by a venous insufficiency syndrome, which allows blood in the veins to escape from normal blood flow. 

In women, the appearance of spider veins can be linked to such factors as heredity, weight gain, hormonal changes and prolonged sitting 

or standing. While mild forms are viewed as a cosmetic problem, spider veins are bothersome and can cause minor aching, burning 

and swelling.

The laser treatments involve a laser light that is directed through the skin into the vein by the laser. The heat causes the vein wall to collapse, seal shut, and then be absorbed by the body.
