Medical adjustable electrotome pen device

Abstract

The invention relates to the technical field of ablation electrodes, and discloses a medical adjustable electrotome pen device. The medical adjustable electrotome pen device comprises a pen body and apen cap which are connected with each other, wherein an adjustable pull tube is arranged in the pen body, the front end of the adjustable pull tube penetrates through the front end of the pen body, acigarette holder and a contact piece are mounted on the adjustable pull tube, and an electrode is mounted at the front end of the adjustable pull tube. An electrotome sleeve is mounted on the electrode, a concave piece is connected to the upper end of the pen body, and a PCB is arranged in the adjustable pull tube. The medical adjustable electrotome pen device can solve the problems that at present, a length-adjustable smoke tube and an electrotome bit are independently separated, the cigarette holder needs to be adjusted according to the length of the electrotome bit, multiple times of adjustment are needed when the position is not ideal, operation time is occupied, when the cigarette holder touches tissue, the cigarette holder retracts, a rotating head is complex in structure, and product cost is increased. The problems that when disposable discarded articles are adopted in existing surgical instruments, expensive cutters become unpractical and infeasible, and the existing surgicalinstruments are poor in air tightness, can be solved.

Description

technical field [0001] The invention relates to the technical field of ablation electrodes, in particular to a medical adjustable electric knife pen device. Background technique [0002] Traditional ablation electrodes, also known as high-frequency surgical electrodes, will produce a large amount of burning smoke and disperse in the process of surgical treatment of physical diseases. When the electric knife touches the tissue, it will produce a carbonization reaction, and this is the visible smoke. [0003] This kind of smoke has been proven to be harmful to the human body abroad, so there are many different types of smoking pens (ablation electrodes) abroad, so that doctors can suck away the harmful smoke when performing electrocautery operations. For example, patent numbers CN102614013A, JP6072956B2, AU2014201190B2 and other patents are all design patents of different types of electrosurgical smoking pens. [0004] In the CN102614013A patent case, the technical feature o...

AI Technical Summary

Problems solved by technology

[0010] Aiming at the deficiencies of the prior art, the present invention provides a medical adjustable electric knife pen device, which has the advantages that the cigarette tip is not easy to retract when it hits the tissue and the rotating head can be connected with the main body of the pipeline structure, which solves the problem of the current adjustable length cigarette. The tube and the cutter head are separated independently. The cigarette nozzle needs to be adjusted according to the length of the cutter head. If the position is not ideal, it needs to be adjusted many times, which takes up the operation time. When the cigarette nozzle touches the tissue, it will cause the cigarette nozzle to retract and the structure of the rotating head is complicated. , increasing product cost, expensive knives become impractical and unfeasible when disposable disposables are used in today's surgical instruments, and their airtightness is not good
