Description

The smokeless electronics scalpel of multi-functional pen type

The smokeless electronics scalpel of the multi-functional pen type of the present invention relates to a kind of surgery instrument, electrode length scalable especially, and have the pen type scalpel of smoke evacuation function.

Existing old-fashioned pen type electronics scalpel if the surgeon need regulate the length of electrode, must be pulled down the electrode part, change then other length electrode.This has just produced several problems: the first, and electrode production producer only produces the electrode of two to three kinds of full-lengths.If the surgeon can not find own ideal length in this two or three kind of full-length, just have to selecting immediate full-length for use; The second, in operation process, change the valuable operating time of electrode waste; The 3rd, when the electrode of selecting for use was long, the opening part of smoke discharging pipe often left cutter and put far away and the effectiveness influence smoke evacuation.In this case, just need add the effect of improving smoke evacuation with a special smoke evacuation cover, but just increase the expense of operation like this.When doing abdominal operation with old-fashioned pen type electronics scalpel, because of smoking problem, effect is undesirable always.Reach ideal smoke discharging effect, the smoke evacuation cover certainly will often block surgical sight line again but discharge fume to overlap very near the operation technique point, thus the operation of influence operation.Defective at old-fashioned pen type electronics scalpel exists the utility model proposes a kind of new technical scheme.

The purpose of this utility model is: provide a kind of standard-sized electrode, but and this standard-sized electrode length regulated at will in use and guarantees effective smoke evacuation effect.

The purpose of this utility model can be achieved through the following technical solutions: the smokeless electronics scalpel of a kind of multi-functional pen type, be a kind of surgical knife that cutting and Blood clotting are arranged, comprise cutting electrode by radio-frequency current control, characteristics are: smoke ejector is along the long axis direction setting of pen type scalpel, and ozzle is connected with the telescopic sleeve pipe assembly.Smoke ejector is connected on the pen type cutting electrode, and smoke evacuation inlet does not need too big adjustment with the electrode tip distance, if guarantee easy to use in doctor's operation, do not keep off sight line, along the long axis direction of cutting electrode the telescopic sleeve pipe assembly is set.The length that makes electrode is with telescopic flexible the adjustment.Described smoke ejector comprises a vacuum pump; Exhaustor is received on the vacuum pump, and the exhaustor other end and sleeve join, and cigarette or fragment are discharged along air flue.The locking cover is connected with telescopic sleeve pipe with sleeve respectively, with fixed electrode length; Ozzle is connected the telescopic other end.Can adopt flexible connection between ozzle and sleeve pipe, adopt groove and the connected mode that projection or pin match, make the ozzle replacing more convenient as between: ozzle and sleeve pipe front end.Ozzle also can be made integrative-structure with sleeve pipe.

On the technique scheme basis, for accelerating flue gas velocity, a cone space district is arranged in this utility model ozzle, from the ozzle top from small to large, make the cigarette that produces in the operation and fragment form eddy current through ozzle inner conical district and enter the sleeve exhaust duct fast and be discharged from.

On the technique scheme basis, the outer surface of described locking cover has a threaded portion, with the screw-internal thread fit of barrel forward end.Adopt between locking cover and sleeve and be threaded.In close threaded portion, sleeve has one to the gradually big cone-shaped inner surface of port.The end that locking is with toothed rim inserts the sleeve cone-shaped inner surface, and toothed rim is blocked and inserted telescopic telescopic sleeve pipe.Certainly, lock solid structure can be an alternate manner also, as long as reach the purpose of locking.

On the technique scheme basis, conductor is connected in the sleeve.Described conductor can be to be made of a pipe fitting that stretches along the sleeve direction.The conductor cover of electric energy on being enclosed within the retractility sleeve pipe is passed in the retractility sleeve pipe.The retractility sleeve pipe comprises: removable sleeve pipe has electric conductor in it.The conduction tang that described electric conductor fingerstall pipe end socket one conductor cover, electrode insert, electric energy are passed to from conductor, the conductor cover that contacts with conductor and conduct electricity tang, cutting electrode.The switch member that the control electrical energy transfer can be arranged on conductor.

This utility model also can cooperate argon blood coagulation device and smoke ejector to use on old-fashioned form of a stroke or a combination of strokes electronics scalpel basis.

Superiority of the present utility model is: electrode length can be by the telescopic tube adjustment; Operating on does not a little need too big variation with the exhaust opening distance, has guaranteed that effective smoke evacuation and surgeon are easy to use; Operation writing of indictments, appeals, etc. body is that sleeve part can use repeatedly; The smoke evacuation of cyclone type has improved smoke exhaust efficiency; Can on old-fashioned form of a stroke or a combination of strokes electronics scalpel basis, cooperate argon blood coagulation device and smoke ejector to use.
