Abstract

The utility model belongs to a medical apparatus, particularly refers to an operation knife blade with calibration, wherein the knife blade [2] is composed by an assembly hole [1], a knife back [3], a tip [5] and a cutting chin [6], characterized in that surface of the knife blade [2] is provided with a calibration [4] that has identification. The knife blade in current clinical usage is a blade with common tip, and depth of the cut at surgery is determined by experience of the doctor and personal judgment, which cannot reach accurate requirement of scheme before surgery. Based on existing blade, mark surface of the knife blade from the tip with calibration in equal distance in series until the narrow end of the assembly hole of the knife blade. The calibration on the blade surface solves problem of hard control of depth of the blade on surgery position.

Description

A kind ofly have a graduated 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 length mark.

Background technology:

Cosmetic surgery is an operation that requirement is very meticulous, so the formulation of pre-operative surgical 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, do not reach the degree of accuracy requirement of design before the art with clinician's experience and subjective judgment.China Intellectual Property Office has announced a kind of graduated scalpel (application number is 2006201311403) that has, though the scale marker on its handle of a knife can be determined the length at operative incision position, the degree of depth of cutter but can't accurately identify down.

Summary of the invention:

The purpose of this utility model is exactly will be provided at can determine the following cutter degree of depth in the operation process a kind of to have graduated knife blade.

A kind ofly have a graduated knife blade, by having pilot hole 1, the knife back 3, the blade 2 that point of a knife 5 and blade 6 are formed is characterized in that: the scale 4 that has length mark on the knife face of blade 2.

According to above-described a kind of graduated knife blade that has, its feature also is: the scale 4 of length mark identifies the direction of the pilot hole 1 on blade 2 successively from an end of point of a knife 5, and apart from blade 6 certain distances.

Description of drawings:

Accompanying drawing is a kind of planar structure sketch map that has graduated knife blade of this utility model, wherein:

Fig. 1 is a kind of planar structure sketch map that has graduated knife blade of this utility model, wherein:

The 1-pilot hole 2-blade 3-knife back

4-scale 5-point of a knife 6-blade

The specific embodiment:

In conjunction with the accompanying drawings, this practical a kind of implementation process that has graduated knife blade of narration: this utility model is a kind of, and to have the enforcement of graduated knife blade very simple, end from the point of a knife 5 of blade 2 processes high scale successively apart from blade 6 certain distances of blade 2 and gets final product.The scale of this equidistant expression length can be identified near the correct position of the comparatively narrow end end of the pilot hole 1 on the blade 2 always and be advisable, and can be identified at the one side of blade 2, also can be identified at the two sides of blade 2 simultaneously.

Embodiment: is example with art with No. 11 sharp knife sheets, end from the point of a knife 5 of this blade, on the plane of blade 2 (promptly avoiding the equidistant inclined-plane of blade 6), with mm is unit has pilot hole 1 successively on blade 2 direction signs high scale, until being advisable near the end correct position of the comparatively narrow end of the pilot hole 1 on the blade 2, be generally 2cm or get final product near 2cm, be convenient identification, with mm is that the graduated length of ultimate unit can be different, the graduated length of 5mm and 15mm place can be longer slightly, 10mm and the comparable 5mm in 20mm place and 15mm place are longer again, also can identify a spot of Digital ID.

This utility model is a kind of to have graduated knife blade, reasonable in design, easy to use, behind the sign scale on the basis of original blade, has solved the cutter depth under the operative site and has been difficult for the difficult problem accurately grasped.

Claims

1, a kind ofly have a graduated knife blade, by having pilot hole [1], the knife back [3], the blade [2] that point of a knife [5] and blade [6] are formed is characterized in that: the scale [4] that has length mark on the knife face of blade [2].

2, a kind of graduated knife blade that has according to claim 1, its feature also is: the scale of length mark [4] identifies the direction of the pilot hole [1] on blade [2] successively from an end of point of a knife [5], and apart from blade [6] certain distance.
