Electric coagulation and electric cutting pliers

Abstract

The invention discloses electric coagulation and electric cutting pliers. The electric coagulation and electric cutting pliers comprise a handle assembly and an electrode assembly, wherein the electrode assembly can perform telescopic clamping motion under the control of the handle assembly, and comprises a first electrode and a second electrode which are mutually isolated; when the first electrode and the second electrode are under an approaching condition of the telescopic clamping motion, the first electrode is embedded in a through groove in the second electrode, and is level with the farend of the second electrode; the first electrode is embedded in the through groove in the second electrode, so that the far ends of the two electrodes are level and insulated; when the electrodes arein contact with tissue, the two electrodes are conducted by the tissue to form a loop, the electric current burns the passing tissue, so that the tissue is subjected to dehydration and modification; and tissue in small region can be clamped by the far ends, so that fine surgery operations are realized, and the effect of point contacting blooding stopping can also be realized, so that the problemsthat existing electric coagulation and electric cutting pliers are poor in surgery operation accuracy, and precise electric cutting and precise electric coagulation cannot be conveniently performed ontarget tissue in the small region are solved.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an electrocoagulation electric cutting forceps. Background technique [0002] With the development of medical technology, the application of minimally invasive visual surgery is gradually increasing in clinical surgery, especially abdominal surgery or gynecological surgery. At present, minimally invasive surgery usually requires a variety of instruments to be used together, such as hysterectomy, which requires electrocutting forceps, electrocoagulation forceps, electrosurgical forceps, and extraction forceps, which are used to cut, coagulate, stop bleeding, and remove tissues. operating. [0003] Due to the limited operating space in the abdominal cavity during surgery, it is difficult to accommodate multiple instruments at the same time. Therefore, the current surgical instruments are continuously improved in integration and multi-function. For example, a cutting knife is arranged si...

Problems solved by technology

[0005] In view of this, the present application provides an electrocoagulation cutting forceps. By changing the electrode structure of the electrocoagulation forceps, the first electrode is embedded in the through groove of the second electrode, and the distal ends of the two electrodes are flush and insulated. When the tissue is in contact, the tissue conducts the two electrodes to form a loop, and the current burns the passing tissue, causing the tissue to lose water and denature. The effect of palpable hemostasis solves the problem that the accuracy of electrocoagulation electric cutting forceps is poor, and it is difficult to conveniently perform precise electrocution and electrocoagulation on small area target tissues
