Description

Novel T-shaped scalpel head area smoking measurement function monopole operation ablation electrode

Technical Field

The invention relates to the technical field of surgical instruments, in particular to a novel T-shaped monopolar surgical ablation electrode with a function of measuring smoking of a cutter head.

Background

The high-frequency electric surgical instrument is widely used in clinical surgery modes as a basic surgical energy instrument, and the position of the high-frequency electric surgical instrument in open surgery cannot be swung. Although the popularization of ultrasonic knives has made them a good place for endoscopic surgery over the past two decades, high frequency electrosurgical instruments such as monopolar coagulation hooks, monopolar electric scissors (as used in da vinci robot), bipolar coagulation (as used in Ligasure, hectic forceps) and the like have also developed rapidly and are widely used in endoscopic minimally invasive surgery. The clinically and conventionally used monopolar high-frequency ablation electrode (including a common surgical electrotome for open surgery and a monopolar electric coagulation hook for endoscopic minimally invasive surgery, a monopolar electric scissors and the like) mainly generates heat and gasifies or coagulates high-impedance tissues by high-frequency high-voltage current. Compared with energy instruments such as an ultrasonic knife and the like, the high-frequency ablation electrode has the advantages that the operations of cutting, separating, stopping bleeding and the like can be performed on tissues efficiently without converting electric energy into mechanical energy.

The monopolar high-frequency electric surgical instruments on the market at present mainly use a monopolar electric knife (mainly for open surgery), an electric coagulation hook and an electric coagulation shovel (mainly for endoscopic minimally invasive surgery), and the defects of the surgical instruments are as follows: firstly, in open or endoscopic surgery, the tool bit of most monopolar high-frequency electric surgical instruments is exposed without a protective layer (such as an electric knife pen, an electric coagulation hook, an electric knife shovel and the like), the whole metal part is exposed beside a surgical target area, and the tool bit part is easy to accidentally injure surrounding tissues during the surgical operation, particularly when fine operations such as cleaning lymph nodes beside blood vessels and the like are carried out, particularly when the electric coagulation hook is used in the endoscopic surgery; secondly, the high-frequency electric surgical instrument cauterizes, stops bleeding and cuts tissues through heat to gasify tissue liquid, smoke generated by gasified tissues is large, and the smoke contains a large amount of toxic gas, so that the health of doctors and nurses on an operation table is greatly influenced in open operations; in the endoscopic minimally invasive surgery, the lens of the endoscope is easily atomized and polluted, so that the observation of the endoscope is influenced, the surgical progress is seriously influenced if frequent smoke suction and air exchange or lens scrubbing are needed, and the safety and the efficiency of the surgery are not improved; thirdly, the cutter head of most single-pole ablation electrodes is sharp, the outer surface of the part of the single-pole ablation electrodes is provided with edges and corners, and when the single-pole ablation electrodes are not electrified for blunt separation, the surrounding tissue plane can be possibly damaged, so that bleeding and the like are caused.
