Abstract

The utility model discloses split type medical scissors, which comprise handles and scissors heads. The handles comprise a left handle and a right handle, wherein the left handle and the right handle are fixed together through a fixed rotary shaft. The scissors heads comprise a left scissors head and a right scissors head. The scissors heads are connected with the handles. The handles and the scissors heads adopt a spit type structure, and the handles and the scissors heads are fixedly combined together through thread connection, riveting connection, or screws. According to the utility model, as the scissors are made into a structure of the handles and the scissors heads and the handles are fixed by the fixed rotary shaft, the scissors heads or the center rotary part can be taken out and replaced with new ones in the case that the scissors cannot be used as a result of broken scissors heads, blunt scissors heads, or damaged fixed rotary shaft. Therefore, the characteristic that the handles are not likely to be damaged is made full use of, the service life of the scissors is prolonged to a maximal degree, the material is saved and the cost is reduced.

Description

A kind of split type medical scissors

Technical field

This utility model relates to the medical device product technical field, is specifically related to a kind of medical scissors, like scissors for surgery etc.

Background technology

Shears is the requisite in routine duties medical instrument of doctor, various shears are various in style as dissect that shears, shaping shears, microscissors, tissue are cut, line is cut, easy shears etc., different, each have their own function.The frequency of utilization of shears and consumption are very large; At present the employed shears of hospital all is an integrative-structure, and promptly scissors bit and handle are integrated, and one is made up of shears two parts; Fix with fixed rotating shaft in middle certain suitable position, just as the fulcrum of lever.The shortcoming that the shears of this existing structure exists is, having grown scissors bit service time can rust, sometimes scissors bit can fracture, fixed rotating shaft (situation such as joint damage; In case these situation take place, shears just can not use, and must integral body scrap; Therefore, hospital all can scrap by a large amount of shears every year.In fact, handle portion still is intact, can also use for a long time, has not only wasted material and it is scrapped, and has also increased cost to society.

The utility model content

The technical problem that this utility model will solve provides a kind of handle and scissors bit is separated from each other, the removable split type medical scissors of scissors bit.

For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of split type medical scissors comprises handle and scissors bit; Handle comprises left handle and right handles; Be fixed together through fixed rotating shaft between left handle and the right handles, scissors bit comprises left scissors bit and right scissors bit, and scissors bit is connected with handle; It is characterized in that: said handle and scissors bit are split-type structural, handle and scissors bit through be threaded, riveted is connected or the screw secure bond together.

Preferably, the front end of said handle offers screw hole, and the tail end of scissors bit is provided with threaded connector, and threaded connector screws in and in the screw hole of handle front end, handle and scissors bit is fixed together.

Preferably, the interface between handle and the scissors bit is positioned at the fixed rotating shaft front, even scissors bit has been broken like this, handle and fixed rotating shaft all need not to change.

Preferably, the interface between handle and the scissors bit is positioned at the fixed rotating shaft back.

Preferably; Whole shears is made up of scissors bit, middle rotating part and handle three parts; The front and back of rotating part in the middle of handle and scissors bit lay respectively at, if scissors bit and handle portion all are intact like this, and middle rotating part has been broken; Rotating part in the middle of then replaceable, scissors bit and handle need not to change.

Preferably, the front end of said handle offers threaded connector, and the tail end of scissors bit is provided with screw hole, and threaded connector screws in and in the screw hole of scissors bit tail end, handle and scissors bit is fixed together.

During fabrication handle is all made standard component together with its screw hole, scissors bit together with its threaded connector; When in case take place that scissors bit fractures, rust etc. causes the out of use situation of shears; Can scissors bit be screwed out, changing new being tightened on then can be as new use on the handle.

This utility model is through making the structure that separately is made up of handle and scissors bit with shears commonly used in the hospital; Fix by fixed rotating shaft between two handles, fracture at shears generation scissors bit, when rust, fixed rotating shaft damage etc. cause its out of use situation, can scissors bit be taken out; And change new scissors bit; Thereby can make full use of the indefectible characteristics of handle, prolong the service life of shears to greatest extent, thereby can save material, reduction use cost.
