Specifications

Laser surgery is widely applied in a variety of human surgical specialties such as: otolaryngology, gynecology, neurosurgery, pl

 

1. Treatment principle

 

The CO2 surgical laser system –CL20(15W) with CE and ISO certificates adopts sealed off CO₂ laser which transmits laser through the guiding light joint arm. The output is invisible infrared whose wavelength is 10600nm, its characteristic are a good direction and high energy density. When the laser transmitted through focus lens, the high temperature produced by the focus spot can gasify, cutting and cauterization the target organ. If the laser not transmitted through the focus lens, the energy density is low, and it can be used for coagulation operation.If the laser transmitted through beam expander, the device can be used in irradiating physical therapy.

 

 

 

2. Structure Performance

 

2.1 Laser tube(laser for short)

 

The laser is made of glass tube filled with CO2 gas. The back end equipped holophote and the front equipped laser resonator that made up of output window glasses. When the electrode of lasers connect with high voltage electric current, the CO2 gas is motivated so as to produce laser and be sent out from the output window. Cooling pipe is equipped inside, and cooling obtained.

 

2.2 The guiding light joint arm

 

It consists of seven joints and a guiding light tube. There are laser reflector slices in the joints. Laser beam gives out after reflecting for many times. The outlet can be assembled with focused lens, all kinds of operation head- knife and expanding beam lens.

 

Application of headpieces,

 

Focus Lens of laser articulated arm F = focal length of 100mm (1F).It

 

(F=100mm) can be used with cutting head-knife (1F) or ENT head-knife, please make sure the output end is away from the skin around 5mm.

 

Other head- knife’s length over 100mm (as:1F, 1.3 F, 1.4F, 1.6 F), far away from the focus, more big spot, the density will be lower, so the heads can be used for solidification.( offering 5 pieces headknife,5 of them are for backup).

 

2.3 Power supply and Control parts

 

It is combined with switching power supply and computer control parts. Adjusting the current of switching power supply can control the output power of the lasers. Control parts are made up of the Micro-computer control panel, data collect board, Liquid crystal display and touch panel

 

2.4 Cooling circle system

 

The large amount of heat will happen when the instrument works. We use the inner circle system to cool off. The pure water is in the tank, which is sent by pump to the laser pipes and reflows to the tank through flow controller.

 

2.5 Instruction laser (DIODE),

 

When the status is on STA-BY, press the key “A. BEAM” to select the red indicate laser work or not. Press the key Continue to select the output status.

 

2.6 Instant stop button

 

Press this button to cut off the power and stop the laser output when the foot switch is out of work or other problems happen. Turn the button clockwise to spring out it so as to restore original position when the problems settled.

 

2.7 Control switch (foot step switch)

 

The foot step switch of the instrument is a kind of drop– proof type suiting for the common laser clinic. The water- proof foot step switch is suit in the operating room.

 

2.8 Protecting cooling water from breakdown

 

If the circle cooling water appears breakdown, the laser tube will be damaged. So the instrument lacks water, or water temperature is over 45 °C, the computer will cut off the power supply and produce the alarm sound automatically.

 

2.9 Safety door link lock

 

To assure safety on operating, the door must be shut. Then connect the switch with “the door link socket" of the instrument. If the door of the operation room is opened when operating, the instrument will stop transmitting laser.

 

 

 

3. Application

 

The equipment is featured by reasonable construction, stable performance, and safety and reliability.

 

The CO2 laser therapy apparatus model is suitable for used extensively in such departments as dermatological, ENT, gynecological and general surgical for cauterization and vaporization treatment. This machine is well suited to use by different levels of hospitals and medical centers. The detailed using scope is as following,

 

3.1. Dermatology: facial cosmetology, body freckle, nevus, tumour, wart, skin cancer, the instrument can excise anything superfluous or useless in order to make people strong and handsome and to prevent pathological changing.
3.2. E.N.T: all kinds of rhinitises, nose polyps, pharyngitises, oral hemangiomas.
3.3. Ophthalmology: orbit tumour, eyelid, sty, double blood skin.
3.4. Gynecology:chronic cervicitis, valvar angiofibromata, cervical erosion, leukoplakiavulvae, excesion uterus polyp , cervical carcinoma in situs, etc.
3.5. General surgery: haemorrhoids, aal fissure and anal fistula, phimosis, V.D. etc.

 

3.6. Physical therapy: inflammatory mass, chronic ulcers, vasculitis, scapulohumeral periarthritis , soft tissue contusion, wound infection.

 

3.7. Others: underarm odour, corn, ulcer.
