Abstract

The utility model provides an inserting assembly type electric operating knife head. The structure of the electric operating knife head comprises a knife rod and a knife bit, the upper end of the knife rod is provided with a conductive plug, the middle of the lower end of the knife rod is provided with a dead hole, the upper end of the knife bit is provided with a conductive plug, the knife rod and the knife bit are tightly connected together through the conductive plug and the dead hole, i.e., the conductive plug of the upper end of the knife bit is tightly inserted in the dead hole of the lower end of the knife rod, and the conductive plug of the upper end of the knife rod is inserted in the lower end of an electric operating knife handle. Compared with the prior art, the electric operating knife head has the advantages of reasonable design, simple structure, safety and reliability, the length of the knife rod can be adjusted, the shape of the knife bit can be replaced, an operatingsurgeon can conveniently use the electric operating knife head to cut or burn human organs or carry out other operations, and therefore the electric operating knife head is worth popularization and application.

Description

A kind of plug combined electric surgical knife bit

Technical field

This utility model relates to a kind of operating theater instruments, specifically a kind of plug combined electric surgical knife bit.

Background technology

Electrosurgical is a kind of surgical knife tool commonly used, the normally straight shape of the working head of the electric surgical knife bit of prior art, be mainly used in the cutting of skin histology, the calcination treatment, the deficiency that the electric knife head of prior art exists in actual clinical is that the shape of cutter head is single, it can only be to the tissue in doctor's sight line or the organ cutting treatment that undergos surgery, and to surpassing intraorganic other position of sight line, such as some organ in the edge of a knife is done to burn or scald treatment, be typically treatment common arrhythmia atrial fibrillation (AF), the cutter head of single shape then obviously exists unable to do what one wishes.In addition the length of the electric knife head of prior art can not with hospital surgical need change, thereby influenced the accuracy and the safety of operation.

Summary of the invention

The purpose of this utility model provides a kind of electric knife pole length scalable, the plug combined electric surgical knife bit that electric knife head is interchangeable.

A kind of plug combined electric surgical knife bit of the present utility model is realized in the following manner, its structure is made up of knife bar and cutter head, the upper end of knife bar is provided with conductive plug, have blind hole in the middle of the lower end, the upper end of cutter head is provided with conductive plug, knife bar and cutter head closely are plugged on blind hole mutually by conductive plug, and the conductive plug of cutter head upper end closely is plugged on the blind hole of knife bar lower end, and the conductive plug of knife bar upper end is plugged on the electrosurgical handle, at its lower end.

The beneficial effects of the utility model are: the length of electric knife bar can operation extends or shortens at difference according to the doctor, and change the head of electric knife according to different operation, to adapt to human body skin or internal organs cut or operative treatment such as burn and scald.

Description of drawings

Accompanying drawing 1 is a kind of main TV structure sketch map of plug combined electric surgical knife bit;

Description of reference numerals: conductive plug 1, knife bar 2, insulation sleeve 3, blind hole 4, cutter head 5.

The specific embodiment

With reference to Figure of description a kind of plug combined electric surgical knife bit of the present utility model is done following detailed explanation.

As shown in Figure 1, a kind of plug combined electric surgical knife bit of the present utility model, its structure is made up of knife bar 2 and cutter head 5, the upper end of knife bar 2 is provided with conductive plug 1, have blind hole 4 in the middle of the lower end, the upper end of cutter head 5 is provided with conductive plug 1, knife bar 2 and cutter head 5 closely are plugged on blind hole 4 mutually by conductive plug 1, the conductive plug 1 of cutter head 5 upper ends closely is plugged on the blind hole 4 of knife bar 2 lower ends, and the conductive plug 1 of knife bar 2 upper ends is plugged on the electrosurgical handle, at its lower end.

The external packets of knife bar 2 is covered with insulation sleeve 3.

Embodiment:

Length according to the operation needs during use can be plugged on a joint or more piece knife bar together by the mode of pegging graft, and the cutter head of selection suitable shape is plugged on the lower end of knife bar, the conductive plug 1 on the knife bar is plugged on general electric knife operating grip get final product.

Electric knife is done and the processing and fabricating of electric knife head is known machining technique.

Except that the disclosed technical characterictic of description, be the known technology of those skilled in the art.
