Plasma surgical electrode realizing bendable direction change of head

Abstract

The invention provides a plasma surgical electrode realizing bendable direction change of the head. The plasma surgical electrode comprises a point electrode, an electrode holder, an outer cutter bar,an outer jacket, an inner cutter bar, an inner jacket, a suction opening and a handle, wherein a pull wire mechanism is arranged in the handle, the pull wire mechanism is connected with the outer cutter bar through a first pull wire and a second pull wire, a bendable structure is arranged at the front end of the outer cutter bar, the inner cutter bar is arranged in the outer cutter bar, a bendable structure is arranged at the front end of the inner cutter bar, the point electrode is arranged at the front section of the inner cutter bar, the suction opening is arranged in the point electrode,the inner cutter bar is of a hollow structure, and the front end of the inner cutter bar communicates with the suction opening of the point electrode, so that a suction flushing channel is formed. Theplasma surgical electrode realizing bendable direction change of the head has the advantages that omnibearing excision can be carried out aiming at the different positions and structures of the lesion parts of patients, the accuracy and effect of the surgery can be guaranteed, the surgery products can be discharged from nearby positions, the surgery precision can be improved, and the surgery timecan be reduced.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a plasma surgical electrode whose head can be bent and changed direction. Background technique [0002] Low-temperature plasma system has been widely used abroad in recent years: the treatment of diseases such as otolaryngology surgery, spine surgery gynecology, dermatology and venereal diseases and anorectal diseases, and has been proved to have good results. It has high safety, short operation time, The characteristics of small trauma and quick effect. The basic principle is that the plasma energy flows between the active electrode and the return electrode, and a highly concentrated plasma vapor sheath is formed around the electrode through the conduction of physiological saline. The plasma sheath is composed of a large number of charged particles. After the charged particles are accelerated by the electric field, they will generate sufficient energy and have strong oxidative propertie...
