Smoke suction pipe connecting structure and smoke suction electrotome

Abstract

The invention discloses a smoke suction pipe connecting structure and a smoke suction electrotome. The smoke suction pipe connecting structure comprises a smoke suction pipe, a locking ring slot, an elastic eccentric sleeve and a projection part, wherein the smoke suction pipe is inserted into a housing handle of the electrotome, the locking ring slot is arranged in the outer circumference of the smoke suction pipe, the elastic eccentric sleeve is arranged in the locking ring slot, and the projection part is arranged on the locking ring slot and matched with the elastic eccentric sleeve. When the smoke suction pipe in the housing handle of the electrotome forwardly rotates by a preset forward angle, the projection part and the elastic eccentric sleeve are matched, so that the smoke suction pipe is radially and axially locked with the housing handle of the electrotome; when the smoke suction pipe in the housing handle of the electrotome reversely rotates by a preset reverse angle, the projection part and the elastic eccentric sleeve are matched so as to unlock the radial and axial locking of the smoke suction pipe and the housing handle of the electrotome. The smoke suction pipe connecting structure and the smoke suction electrotome have the advantages of simple structure, convenience in operation and convenience in replacement and adjustment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a connection structure for a smoking pipe and an electric knife with the structure. Background technique [0002] Electric knife is a common surgical knife, because a lot of smoke will be generated during surgical cutting, which will block the doctor's sight and affect the normal operation of the operation, so most of the current electric knife has a smoke absorption function, through The vacuum adsorption device sucks out the smoke generated by the operation to ensure the normal and smooth operation of the operation. For example, the Chinese utility model patent with the patent application number of CN 200920053974.0 and the application date: 2009-04-03 discloses a smoking electric knife pen. Its structure includes a pen body shell, an electrode cutter head and a smoking pipe. There are control buttons on the pen body shell, and a circuit structure is installed. The smok...

Problems solved by technology

[0003] However, in actual production, sales and use, more complex operations are often not able to be completed with a single electrode, and electrodes need to be replaced. In such operations, many hospitals and doctors are often reluctant to use existing electrodes. Some electrosurgical units with smoking tubes limit the scope of application of the electrosurgical unit
