Description
Technical field
The present invention relates to medical auxiliary equipment, more particularly, to a kind of multifunction surgical electric knife.
Background technology
With continuing to develop for medical technique level, application of the electrosurgical in surgical operation is more and more extensive, can use
In operation techniques such as cutting, drying, blood coagulation, cauterise tissues.Existing electrosurgical only one of which electric knife head, is needed in surgical procedure
When using cutter head of different shapes, generally using two methods of replacing electrosurgical and replacing electric knife head.In surgical procedure
Multiple electrosurgicals are used simultaneously, and circuit is more and chaotic, operation inconvenience, and because electrosurgical is mostly disposable, wave
Take material, therefore existing general many methods using replacing electric knife head are changed, on the electric knife head in Renewal process after use
Heat it is big, easily scald medical personnel, and electric knife head is smaller, easily drops in patient, influence sufferer health.
The content of the invention
Present invention aims at providing, one kind not only has multiple cutter heads and tip shapes are different, also there is smoke abatement to make
Multifunction surgical electric knife.
To achieve the above object, the present invention takes following technical proposals：
Multifunction surgical electric knife of the present invention, including the first insulation tube, the second insulation tube, conducting element and with plug
Electric power connection line, first, second insulation tube is fixed with one by pipe joint, and being provided with coagulation on the second insulation tube opens

Limiting plate, be uniformly equipped with multiple structure identical handle of a knife units on the limiting plate；
The handle of a knife unit includes handle of a knife and the adjusting rod being plugged at the top of the handle of a knife, and cutter head is fixed with handle of a knife bottom；Institute
The first insulation tube upper end is stated to offer and the one-to-one guide groove of handle of a knife unit, first positioned at the guide groove both sides
The guide rail extended from its top down is provided with insulation inside pipe wall, the guide groove is staggered with the guide rail, guide groove
Length be more than the length of guide rail, the adjusting rod is plugged in the guide groove and slided along guide rail；
The adjusting rod is insulating bar, and adjusting rod includes the body of rod, and the upper end on the outside of the body of rod is fixed with button, the guiding
The length difference of groove and guide rail is more than or equal to the length of button；Body of rod clear width is provided with convex platform and lower convex platform, it is described
The longitudinal section of upper and lower boss is trapezium structure or the step-like structure being connected by trapezium structure, under the lower convex platform
Limiting stand is provided with the body of rod of side, compression spring is arranged with the handle of a knife between the limiting plate and limiting stand；
Offered along its length on the body of rod and connecting wire is equipped with mounting hole, the mounting hole, the connection is led
One end of line is connected with the handle of a knife, the other end of the connecting wire extend the pipe joint and with the conducting element
Electrical connection.
The first insulation tube lower end is arranged with suspended hood, the side wall of the suspended hood and offers through hole, described logical
Aspiration channel is provided with and communicated with hole, the aspiration channel is connected on first insulation tube and/or the second insulation tube by line card,
The port of export of aspiration channel is connected with the air inlet of getter device.
The port of export of first insulation tube forms up big and down small bowl-shape or reverse frustoconic structure for interior receive downwards.
Being shaped as the cutter head is spherical, annular, aciculiform, rectangle or blade-shaped, the knife of multiple handle of a knife unit handle of a knife lower ends
Head shapes are different.
Insulation sleeve is arranged with the handle of a knife of each handle of a knife unit.
Compared with existing electrosurgical, multifunction surgical electric knife of the present invention has advantages below：
（1）The present invention has multiple handle of a knife units, and the tip shapes of each handle of a knife unit are spherical, annular, aciculiform, rectangle or knife
One kind of piece shape and different, the handover operation of different shape cutter head can be realized by adjusting rod, and then meet surgical procedure
In a variety of demands；The handover operation process of different shape cutter head is as follows：Two of which handle of a knife unit is respectively designated as first
Handle of a knife unit and the second handle of a knife unit, by taking the switching of first, second handle of a knife unit as an example, when the adjusting rod of the first handle of a knife unit exists
When sliding down to guide rail end along guide rail in guide groove, its button is just installed in the guide groove below guide rail, now should
The cutter head of handle of a knife unit extends outward the outlet of the first insulation bottom of the tube；When handover is needed, the second handle of a knife list is pressed downwards
