Description

A kind of knife blade

Technical field:

This utility model belongs to a kind of medical apparatus and instruments, especially relates to a kind of knife blade that has scale marker.

Background technology

The operation that some is comparatively meticulous has comparatively strict requirement to the scalpel depth of cut, as cosmetic surgery.So the formulation of pre-operative surgical cutter scheme must be very careful, particularly the depth at operative incision position, length have very strict requirement.The knife blade that uses at present clinical mostly is common tip blade, though use the most operations of this blade can reach comparatively ideal results of the preceding designed scheme of art, but be mostly to implement for the degree of depth at operative incision position and length, be difficult to reach the desired depth of cut of delicate procedure with clinician's experience and subjective judgment.

Summary of the invention

The purpose of this utility model is exactly to overcome the defective that the general surgery blade does not have the scale indication, is provided to determine a kind of knife blade of the cutter degree of depth down in the operation process.

The technical solution of the utility model is: a kind of knife blade, the knife back, point of a knife, pilot hole are arranged on it, and on the knife face of the close knife back relative graduation mark is arranged with the knife edge.

Described graduation mark spaced set is distributed on the positive and negative of knife face symmetrically, to adapt to the different customs of doctor right-hand man.

Beneficial effect: do not changing on existing knife blade and the operation knife rest specification standards basis, because indicating graduation has been arranged on knife blade, in the process of performing an operation, the doctor can observe the concrete degree of depth of feed easily, convenient and practical, suitable comparatively meticulous operation.
