Annular variable-focus suction illumination surgical electrode

Abstract

The invention discloses an annular variable-focus suction illumination surgical electrode. The annular variable-focus suction illumination surgical electrode comprises a cable, a high-brightness LED lamp, a lamp source control switch assembly, a function key, an annular LED lamp, a suction connector, a pen-shaped shell, a silica gel ring, an annular convex lens assembly, an electrode rod assemblyand a sleeve, and is characterized in that the head end of the pen-shaped shell is provided with a spiral connecting section; the annular LED lamp and the silica gel ring are arranged on the inner periphery of the spiral connecting section; the spiral connecting section is connected with the annular convex lens assembly; and the illumination intensity is adjusted by adjusting the distance betweenan annular convex lens of the annular convex lens assembly and the annular LED lamp. The illumination intensity can be adjusted by adjusting the distance between the convex lens and the annular LED lamp according to the actual situation under the condition that the electrode rod assembly stretches out or draws back, and installation / adjustment is convenient. Meanwhile, a high-brightness LED lamp light source is arranged at the tail end to complement the central brightness of the electrode rod assembly, and smoke and liquid suction of the surgical electrode is achieved through relative stretching of a scraping and sucking pipe and a tool bit pipe on the electrode rod assembly.

Description

technical field [0001] The invention relates to the technical field of electrosurgical instruments, and is a multifunctional dissector (ablation electrode) used in connection with a high-frequency host, in particular to a ring-shaped variable-focus suction lighting electrosurgical pencil. Background technique [0002] In general, due to the different types of surgery, the affected lesion sites and tissues are different, surgical electrodes (electrosurgical pens) with different functions and different lengths need to be used. The field of vision is too dark in complex deep surgery and narrow entrance surgery, so products with stretched lighting gradually appeared. [0003] At present, the common stretching / stretching products with lighting on the market are single-sided lighting or double-sided lighting, and there is a problem that with the stretching of the electric knife and pen, the lighting intensity of the LED light source will be significantly weakened, and at the same ...

AI Technical Summary

Problems solved by technology

[0002] In general, due to the different types of surgery, the affected lesion sites and tissues are different, surgical electrodes (electrosurgical pens) with different functions and different lengths need to be used. The field of view is too dark in complex deep surgery and narrow entrance surgery, so products with stretchable lighting gradually appeared

[0003] At present, the common stretching / stretching products with lighting on the market are single-sided lighting or double-sided lighting, and there is a problem that with the stretching of the electric knife and pen, the lighting intensity of the LED light source will be significantly weakened, and at the same time, it will be on the electrode. One side of the rod (double-sided lighting forms too dark phenomenon on both sides) forms too dark phenomenon, which affects the doctor's observation

Moreover, the surgical smoke and intraoperative bleeding fluid generated during the operation will affect the doctor's intraoperative observation operation, thereby affecting the success rate of the operation. If the surgical smoke is not cleared in time, even cancer cells will enter the doctor's respiratory tract through the smoke, which is harmful to the doctor's health. cause serious danger
