Intra-operative dissector

Abstract

The invention relates to the field of surgery medical apparatus and instruments, in particular to an intra-operative dissector. The intra-operative dissector is characterized by comprising a sleeve (1), electrodes (2), a handle (3), controlling panels (4); the handle (3) is of a cavity structure; the sleeve (1) comprises an inner pipe (11) and an outer pipe (12); the inner pipe (11) is connected with the outer pipe (12) in a movable mode; a clamping groove is formed in an internal port of the inner pipe (11), and the clamping groove is electrically connected with the controlling panel (4) through wires; the electrodes (2) are mounted in the clamping groove; and discharging ports of the electrodes (2) extend outside a port of the sleeve (1). The intra-operative dissector has the beneficial effects that a low temperature coagulating and cutting mixed mode is achieved, and high temperature damage is avoided on the premise of not affecting the cutting effect; by the arrangement of the clamping groove, different usage of the electrodes can be changed rapidly in an operation; no battery is arranged in a lighting device, so that pollution caused by a battery to the intra-operative dissector is effectively prevented, and electromagnetic interference caused by the lighting device to the controlling plates can also be removed; and a smoke guiding pipe is arranged, and therefore, multiple functions of pumping out smoke, pumping out percolate, leading in argon and leading in cleaning solutions by externally connecting different equipment can be achieved.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to an intraoperative dissector. Background technique [0002] The intraoperative dissector, also known as the electrosurgical pen, is currently widely used in surgical operations and is an electronic surgical instrument that replaces mechanical scalpels for tissue cutting. [0003] The working principle of the electric knife pen is to pass the high-frequency current through the electrode to reach the target tissue, and the part close to the target tissue and the electrode is rapidly heated and vaporized by the high-frequency current. In the specific operation process, the functions of cutting and coagulation are respectively realized through the frequency change of the high-frequency current. [0004] In the prior art, the control board of the electric knife pen is all one, and its strong and weak current signals are all output through the same control board, and the hig...

AI Technical Summary

Problems solved by technology

This results in that when the output power of the coagulation mode is guaranteed, some tissues cannot be cut in the cutting mode; when the power is increased to meet the cutting needs, the coagulation power will be too high, causing thermal damage to human tissues

[0006] At the same time, in order to avoid cross-infection during use, the electric knife pen cannot be reused many times

However, the traditional fixed electrosurgical pen cannot replace the electrodes, so it is necessary to use multiple electrosurgical pens with different electrodes to complete certain operations, which adds unnecessary economic burden to patients.
