Description

And dress pin type electric knife head

Technical field

This utility model relates to a kind of improvement of electro-medical cutter head, specifically a kind of and dress pin type electric knife head.

Background technology

The electro-medical cutter head is the common tool when making surgical operation clinically, is mainly used to cut and organize, and hemostasis, electric knife head is fixed on the end of handle.The electric knife head that uses is flat at present, and knife face is big and thick.The weak point of its existence is: the one, be difficult to scale removal, and when removing electric knife head dirty, generally be to scrape with blade, remove bothersomely, also can damage electric knife head sometimes; The 2nd, because cutter hub broad, thicker, enlarged the wound face of tissue and hemorrhage, in pediatric surgery, microsurgery Minimally Invasive Surgery, operation is difficulty more especially.

Summary of the invention

The purpose of this utility model is to provide a kind of volume and surface area all less, energy easily concentrates on the cutter head tip, undergo surgery cut and organize, energy delivery is fast when stopping blooding, time is short, little and the minimizing amount of smoke of coking amount when burning, and simple in structure, be easy to and adorn, and scale removal disinfectant and adorn the pin type electric knife head separately.

For reaching above purpose, the technical scheme that this utility model adopted is: should and adorn the pin type electric knife head, constitute by needle point and shank, it is characterized in that on shank, being fixed with flat sleeve pipe, the length and width of flat telescopic endoporus is consistent with the length and width of the transverse section of electric knife head, can closely cooperate when making electric knife head insert in the flat sleeve pipe.This utility model is also implemented by following measure: described shank is solid shank, and diameter is 0.5mm-1.0mm, and needle point is the inclined-plane, and syringe needle and shank are an integral body, can disposablely make; Shank and flat sleeve pipe are an integral body, can disposablely make, and needle point grows 10mm than flat sleeve pipe, and flat telescopic wall thickness is 0.5-1.0mm; The sheath of also setting up defences on shank and needle point pollutes preventing, after being sleeved on the electric knife head, can slough protective jacket.When using this utility model, hand-held shank part with the flat sleeve pipe on the shank and be enclosed within on the electric knife head, is sloughed protective jacket and can be used.

The beneficial effects of the utility model are: compare with the electric knife head of present use, volume is little, little with tissue contact surface, it is strong that power is burnt in the part, and wound and hemorrhage slight is specially adapted to pediatric surgery, microsurgery Minimally Invasive Surgery, make operation technique more accurately with meticulous, in addition, this electric knife head is simple in structure, make easily, cost is low, scale removal and smoke, steam, steep sterilization separately, and is easy to use.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,2.Should and adorn the pin type electric knife head, be made of needle point 1 and shank 2, be fixed with flat sleeve pipe 3 on shank 2, the length and width of the endoporus 4 of flat sleeve pipe 3 is consistent with the length and width of the transverse section of electric knife head, can closely cooperate when making electric knife head insert in the flat sleeve pipe 3.Described shank 2 is solid shank, and diameter is 0.5mm-1.0mm, and needle point 1 is the inclined-plane, and needle point 1 is an integral body with shank 2, can disposablely make; Shank 2 is an integral body with flat sleeve pipe 3, can disposablely make, and needle point 1 grows 10mm than flat sleeve pipe 3, and the wall thickness of flat sleeve pipe 3 is 0.5-1.0mm; The sheath (not marking among the figure) of also setting up defences on shank 2 and needle point 1 with anti-pollution, after being enclosed within on the electric knife head, can be sloughed protective jacket.
