Leep knife full name cuts art for annulus of high frequency electric wave, it is method of home's at present most advanced disease of remedial palace neck. It is current clinical and commonly used operation means, it uses the high-energy electrode of all sorts of configuration to arrive directly at pathological changes place, below the action of high temperature electric energy, can organization of rapid, accurate excision pathological changes, cut is automatic and caky, haemorrhage is few, operation time is short, harm is little, it is the admirable choice that treats palace neck disease.
The main job principle of Leep knife. Leep knife is to use high frequency radio the knife tells LOOP wire by electrode most advanced generation the UHF of 3.8 megahertz (microwave) electric wave, in the instant that contacts body organization, by the organization itself produces impedance, absorb electric wave to produce high fever, make the moisture inside the cell forms vapour wave to finish all sorts of cut, hemostatic wait for operation purpose, but the pathology examination that does not affect cut brim organization.
The main good point of Leep knife. Leep knife is comprised by a variety of electrode, include form of annular, globose, needle, triangle (cone-shaped) , square.
Include radio frequency technology all functions: Cut, cruor, melt, evaporate, bright of clear, contractive, report (all functions that include laser and electric knife, and the side-effect that does not have them) ;
The operation is accurate, the very careful operation effect that can achieve short of of traditional report knife;
Small achieve: Without pressure cut, constituent loss is small (scathing deepness is less than 20 micron, rarely fiber is formed, scar happens rarely after art) ;
Produce the phenomenon of the constituent drag that place of traditional report knife causes, carbonization rarely, the patient that makes an appointment with 2/3 can get do not affecting the constituent specimen of pathology examination.
Anguish is small, need not anaesthetic or use local soak anaesthesia only, complication is little (haemorrhage and infection are little) ;
Safe: Do not need negative pole and ground wire, without get an electric shock the danger that reachs burn;
Do not have special requirement to surgery, can undertake in outpatient service;
Excise canceration area only, was Yo age female to withhold an uterus, of utmost withheld birth function.
Leep knife is applicable limits of disease of department of gynaecology. Chronic palace neck is phlogistic: Neck of blaze of neck of evaginate of neck of palace neck debaucjed, palace, palace, palace is polypous (the neck is in charge of inside big polyp or much hair are polypous) ; Palace neck wet wart, inferior clinical HPV infection is usable medication, but if HPV-16, HPV-18 or amalgamative CIN, or pathological changes range is bigger, termless along with the person that visit, should go physical cure or LEEP cure; CIN; Suspect CIN2 or CIN3: 鳦 IN1 or CIN1 follow the patient that visits inconvenience in. CIN3 includes to be ordered again SARS hyperplasia and former a cancer, and LEEP is applied to only spend SARS hyperplasia again, but unfavorable use at palace neck former a cancer, LEEP is treated former the recrudescent rate of a cancerous hind is 29% , and the recrudescent rate after the Leng Dao that pass is treated is 6% ; Suspect shape of palace neck SARS scale the cell.
