Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of pathological material-drawing knife.
Background technology
In life science and every-day medical work, drawing materials of various organization specimen is its important ingredient, the quality of drawing materials is directly connected to the quality of tissue slice, even last pathological diagnosis, and desirable pathological tissue fetching knife is then the important prerequisite ensureing this work.The single cutting tool of the many employings of current pathological material-drawing knife disposable draw materials blade or needs regularly grinding, work efficiency is reduced like this in the process of allowing blade replacement, and operator need in the both sides of fetching knife firmly when drawing materials, but the fetching knife used at present is all generally hilted broadsword handle, inconvenient operation, even can careless due to user, and cause oneself injury.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of pathological material-drawing knife, can not only meet the spacing of adjustment two blades, cut out the pathological section varied in size, and this pathological material-drawing knife provides double-edged blade and double-pole handle, can increase work efficiency, and easy and safe to operate.
The technical scheme in the invention for solving the technical problem is: a kind of pathological material-drawing knife, comprise handle of a knife, cutter hub and bearing pin, handle of a knife and cutter hub pass through pinned connection, described handle of a knife is double-pole handle, be divided into two, left and right, double-pole handle respectively with the pinned connection of the left and right sides, described left and right sides handle of a knife equal and opposite in direction, handle of a knife side is provided with groove, and described depth of groove is greater than the width of cutter hub; Described bearing pin is provided with graduation mark, and bearing pin is provided with slide block, and described slide block is bolted on bearing pin by tight lock, and slide block is connected with sliding blade, and junction is provided with trip bolt, and a side of described sliding blade is concordant with the ipsilateral of slide block; Described cutter hub comprises fixed blade and sliding blade, and described fixed blade two ends are fixedly mounted on bearing pin, concordant with the starting point of the graduation mark on bearing pin inside fixed blade, and described fixed blade and sliding blade are double cutting edge.
As optimization, described handle of a knife and pinned connection end are semicircle, and the other end is provided with rounding.
As optimization, outside described handle of a knife, be provided with anti-slip veins.
As optimization, described fixed blade and sliding blade all select stainless steel material.
The beneficial effects of the utility model are: the spacing that can not only meet adjustment two blades, cut out the pathological section varied in size, and this pathological material-drawing knife provides double-edged blade and double-pole handle, can increase work efficiency, and easy and safe to operate.
