Description
Technical field
This utility model relates to technical field of medical instrument, is specifically related to a kind of cutting blade used for pathologic diagnosis.
Background technology
When carrying out tissue slice in pathological diagnosis, the comparatively ideal volume of taken piece of tissue is 2.0cm × 2.0cm × 0.3cm, so that fixative can penetrate into organization internal quickly and evenly, but different with purpose according to Materials for slide making, the more satisfactory volume of piece of tissue is also different.At present, the fetching knife that Pathology Deparment uses mainly is made up of handle of a knife and cutter hub, and tissue can be drawn materials by this pathological material-drawing knife, but can not accurately control the depth of cut and depth of cut, can only control with the feel of medical worker, so very inaccurate, thus adding the diagnosis difficulty of disease.
Utility model content
This utility model purpose is to provide a kind of cutting blade used for pathologic diagnosis, and it can efficiently solve problem existing in background technology.
nullIn order to solve problem existing in background technology，It comprises knife bar 1 and ceramic tip corresponding thereto 2，The cylindrical structural of described knife bar 1 generally hollow，One end of described knife bar 1 is provided with and clamps seat 3，This clamps seat 3 generally conical structure，Its outer surface is provided with external screw thread 8，The described vertex of a cone face clamping seat 3 is located close to one end of knife bar 1，The described other end clamping seat 3 axially inwardly sets out and clamps groove 4，What this clamped groove 4 is internally provided with rubber layer 5，The bottom of described rubber layer 5 is provided with arc catching groove 6，The contact surface place of described rubber layer 5 and ceramic tip 2 is provided with anti-slip veins 12，The root of described ceramic tip 2 is provided with the clamping and fixing block 7 corresponding with clamping groove 4，The end of this clamping and fixing block 7 is provided with the fixed block 13 being clasped with arc catching groove 6，Described knife bar 1 is provided be socketed with it coordinate clamp nut 9，This clamps the female thread of nut 9 and spins with external screw thread 8 and coordinate，It is provided with dip stick 10 in described knife bar 1，The bottom of described knife bar 1 is provided with the end cap 11 coordinated that spins with it.
The external diameter of described end cap 11 is slightly larger than the external diameter clamping nut 9.
Described anti-slip veins 12 is breast convex architecture.
Clamp in groove 4 when ceramic tip 2 is inserted into, clamp nut 9 and be screwed into clamping and fixing block 7 top when screwing, the both sides interference fit of described rubber layer 5 and ceramic tip 2.
Owing to have employed above technical scheme, this utility model has the advantages that simple in construction, easy to use, it is possible to controls the depth of cut and depth of cut exactly, improves the accuracy of pathological diagnosis.
