Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of resistance temperature Digital Control formula vein and melt
Instrument.
Background technology
Varicosis is common venous disease, refers to that cause is quiet due to factors such as blood stasis, vein tube wall weaknesses
Arteries and veins is tortuous, expansion.The vein at the multiple position of human body all can occur varicose, such as hemorrhoid to be exactly a kind of varicosis in fact, clinical
Visible also have esophagus fundus ventricularis varication, varicocele and abdominal wall varicosis etc..Varicosis occurs most frequently
Position is at lower limb.According to medical statistics, the Adult Groups of 8.8%～10% suffers from obvious varicosis.It is emphasized that
Along with progression of disease, there is stasis dermatitis, superficial thrombophlebitis, hemorrhage, skin ulceration in most patients, have a strong impact on patient
Physical and mental health, even disables.
Operation is the basic method for the treatment of varicose veins of the lower extremity.Traditional surgical approaches is that High ligation of great saphenous vein strips off
Art.Occurring in that printing opacity looks at rotary-cut art, laser Closure straight in recent years, the operation such as radio-frequency (RF) ablation Closure and chamber mirror communicating branch is controlled
Treatment method.But these method costs are big, relapse rate is higher.
High frequency ablation art is the important component part of this art formula.Because of individual patients condition difference in art, only by patient's
Experience controls high frequency pin power, translational speed and skin temperature, weighs without objective indicator, is easily caused skin burn after changing patient
Or treatment is not thorough, is unfavorable for promoting on a large scale.And traditional vein to melt instrument longer owing to melting head end, caliber is relatively thick,
It is suitable only for the intraluminal ablation of above-knee great saphenous vein, it is impossible to process branch at one's knees, and operates relatively cumbersome, patient and spend relatively
Height, is unfavorable for promoting on a large scale.
Summary of the invention
It is an object of the invention to provide a kind of resistance temperature Digital Control formula vein ablatograph, to solve prior art
