Description

A kind of operation electrotome pen

Technical field

The utility model relates to surgical procedures common tool technical fields, more specifically, it relates to a kind of operation Electric knife-pen.

Background technique

Operation electrotome pen is a kind of electrosurgical unit for replacing mechanical operation knife to carry out tissue cutting.The knot of operation electrotome pen Structure includes handle body, cutting operation key, coagulation operation key and connecting wire, the high-frequency and high-voltage that it is generated by active electrode tip Tissue is heated when electric current is contacted with human body, the separation and solidification to injected organism tissue are realized, to play cutting and hemostasis Purpose.It, can in the tissue when the working principle of electric knife-pen is that the high-frequency high-voltage current that electric knife generates passes through the tissue of high impedance Heat is generated, tissue is caused to gasify or solidify.In electrosurgery use process, resistance ohm is differed from 100 ohm to 2000.With The solidification of tissue, the water in cell can gasify, and keep tissue dry, cause resistance to be continuously increased, last electric current stops completely. But high temperature is formed by tissue charring dirt and can not remove shadow in time when presently, there are in electrosurgical nib due to coagulation, cutting The problem of ringing cutting again of performing the operation, the process separated, needs to stop working in use, carries out scaling operation.

In order to accelerate procedure, overcome the shortcomings of that operation electrotome pen is unable to scale removal, it would be desirable to which one kind being capable of mechanicalness A kind of descaling type operation electrotome pen of scale removal.

Utility model content

In view of the deficienciess of the prior art, having the purpose of this utility model is to provide a kind of operation electrotome pen The characteristics of convenient for cleaning scale removal.

To achieve the above object, the utility model provides following technical solution:

A kind of operation electrotome pen, including the electric knife head and electric knife handle being detachably connected, the electric knife handle is close to electric knife head Inside is provided with the slideway being arranged along its length, and the descaler of the extended electric knife handle is equipped in the slideway, described to remove Dirty device is connected with the driving assembly being set in the slideway.

By using above-mentioned technical proposal, electric knife head is detachably connected with electric knife handle, is conveniently replaceable various electric knife heads, is applicable in It is applied widely in the electric knife head of different model, descaler is released outside electric knife handle using driving assembly, thus along electric knife head Length direction displacement, the tissue eschar being attached on electric knife head is scraped, and similarly descaler can be accommodated in by operation when not used In the slideway of electric knife handle, save space, the device can by it is tissue charring dirt quickly it is clean dispose, save the time.

Further, the driving component includes the reset spring that one end is connected with descaler, and the reset spring is another End is connected with the slideway far from the end of electric knife head.

By using above-mentioned technical proposal, under the general state of reset spring, descaler is contracted in inside slideway, is passed through It stretches reset spring to release descaler outside electric knife handle, in addition repeatedly the stretching shrinkage operation of reset spring helps to remove electric knife Tissue eschar on head.

Further, the driving component further includes being set to the reset spring close to descaler side and end can prolong The handle of slideway is stretched out, and is provided with the recessing groove being arranged along its length on the outside of the slideway, the handle is along described Recessing groove sliding.

By using above-mentioned technical proposal, the handle of setting is also convenient for changing and reset convenient for operating entire descaler Operation handle is convenient in the presence of the state of spring, recessing groove.

Further, the recessing groove is connected with the card slot being circumferentially arranged along electric knife handle far from electric knife head one end.

By using above-mentioned technical proposal, card slot is used to block handle, thus handle is circumferentially gone to along electric knife handle to In card slot, so that reset spring will not be influenced arbitrarily to change stretching or contraction state by external force, it in addition can be with this lifting restoring bullet The service life of spring.

Further, the descaler includes cyclic annular scraper, and the ring-type scraper is vulcanized rubber, and the ring-type scraper leans on Nearly electric knife head side is equipped with epoxy coating.

By using above-mentioned technical proposal, the tensile properties of vulcanized rubber can be suitable for the electric knife of different-diameter Head, the detachable structure concord with preamble pair, and the epoxy coating on the outside of cyclic annular scraper is set, it improves whole Rubbing fastness can effectively scrape the tissue eschar being attached on electric knife head.

Further, the cavity being circumferentially evenly spaced on along it is offered inside the cyclic annular scraper, in the cavity Impact direction is placed with perpendicular to the tension spring of electric knife head.

By using above-mentioned technical proposal, the use longevity of cyclic annular scraper is can be improved in the cavity and tension spring of setting Life, the tension effects of another aspect tension spring can preferably improve cleaning effect.
