Abstract

The utility model discloses a novel scalpel which comprises a handle (1) and a blade (2), a groove (3) is formed in one end of the handle (1), the tail portion of the blade (2) is fixedly mounted in a groove (3), length scale marks (4) are arranged on the top of the handle (1) and perpendicular to the side faces of the handle (1), antiskid patterns are arranged on the two side faces of the handle (1), and values on the length scale marks (4) gradually increase from the tail portion of the handle (1) to the top portion of the handle (1). The novel scalpel has the advantages that the structure is simple, the scalpel is skidding resistant, a doctor does not need to observe the length scale marks by tilting the head, operation is simple, and the novel scalpel can be used in a narrow place.

Description

A kind of New knife

Technical field

This utility model relates to technical field of medical instruments, particularly a kind of New knife.

Background technology

General surgery is important subscience of surgery.The scope that surgery is contained is larger, comprising: thyroid, mammary gland, liver and gall gland, gastrointestinal, liver sausage, part peripheral blood vessel etc.; Scalpel is the disease location of human body to be controlled to a kind of medical apparatus and instruments of incision, Resection in Treatment, closely for centuries, surgical knife in medically application is metal blade and handle of a knife composition both at home and abroad, various models scalpel before applying to operation, all need first to sterilize, through normal saline washing or with gauze, dry again, then just blade is arranged on handle of a knife.

During operative doctor excision patient pathological tissues, for avoiding cutting, deeply injure normal structure and Qie get and cross the shallow phenomenon that can not excise again diseased tissues completely.Therefore, most surgical knifes are provided with graduation mark on side, as shown in Figure 1, when armarium is measured after the size of pathological tissues, operative doctor relies on scalpel high scale line to excise patient's pathological tissues, but doctor always needs side head to read graduation mark in excision process, and doctor just can complete the accurate resection operation of pathological tissues, thereby brought inconvenience to the operation of operative doctor, and be difficult to use in the narrower and small place of surgical environments.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, anti-skidding, doctor without side head observe length graduation mark, simple to operation, can be at the narrow and small local New knife using.

The purpose of this utility model is achieved through the following technical solutions: a kind of New knife, it comprises handle of a knife and blade, one end of handle of a knife arranges groove, the afterbody of blade be fixed on recessed in, the top of handle of a knife is provided with length graduation mark, length graduation mark all arranges perpendicular to handle of a knife side, and the size of described length graduation mark is increased to handle of a knife top successively by handle of a knife afterbody.

Two sides of described handle of a knife are provided with anti-skid design.

The utlity model has following advantage: it is convenient that (1) length graduation mark of the present utility model is arranged on the top view of handle of a knife, after in blade incision pathological tissues, surgeon moves handle of a knife and only need observe the numerical value of the length graduation mark that is arranged on handle of a knife top, when the distance moving when length graduation mark equals the length value of pathological tissues, illustrate that this pathological tissues is excised completely, therefore doctor observes graduation mark without side head, have simple to operation, can be narrow and smallly locally using, feature simple in structure.(2) two of handle of a knife of the present utility model sides are provided with anti-skid design, thereby have prevented that surgeon is when cutting pathological tissues, and scalpel drops makes troubles to doctor's operation.

Accompanying drawing explanation

The surgical knife that Fig. 1 is traditional;

Fig. 2 is front view of the present utility model;

Fig. 3 is top view of the present utility model;

The A-A cutaway view of Fig. 4 Fig. 3;

In figure, 1-handle of a knife, 2-blade, 3-groove, 4-length graduation mark.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further described, protection domain of the present utility model is not limited to the following stated:

As in Figure 2-4, a kind of New knife, it comprises handle of a knife 1 and blade 2, one end of handle of a knife 1 arranges groove 3, the afterbody of blade 2 is fixed in groove 3, and the top of handle of a knife 1 is provided with length graduation mark 4, and length graduation mark 4 all arranges perpendicular to handle of a knife 1 side; Two sides of handle of a knife 1 are provided with anti-skid design; The size of length graduation mark 4 is increased to handle of a knife 1 top successively by handle of a knife 1 afterbody.

Work process of the present utility model is as follows: surgeon, with before this surgical knife excision patient pathological tissues, first needs to measure with professional armarium the length of pathological tissues, then just can carry out resection operation.After in blade 2 incision pathological tissues, the scale value that surgeon moves handle of a knife 1 and only need observe the length graduation mark 4 that is arranged on handle of a knife 1 top, when the distance moving when length graduation mark 4 equals the length of pathological tissues, illustrate that this pathological tissues is excised completely, therefore doctor observes graduation mark without side head, have simple to operation, can be narrow and smallly locally using, feature simple in structure.

Claims

1. a New knife, it is characterized in that: it comprises handle of a knife (1) and blade (2), one end of handle of a knife (1) arranges groove (3), the afterbody of blade (2) is fixed in groove (3), the top of handle of a knife (1) is provided with length graduation mark (4), length graduation mark (4) all arranges perpendicular to handle of a knife (1) side, and the size of described length graduation mark (4) is increased to handle of a knife (1) top successively by handle of a knife (1) afterbody.

2. a kind of New knife according to claim 1, is characterized in that: two sides of described handle of a knife (1) are provided with anti-skid design.
