Abstract

The utility model relates to the field of medical instruments, provides an operating knife which overcomes the defects that an existing operating knife is relatively lagging, pressure intensity of a cutter edge is not high enough, contact area of a knife rear and a knife rear side face is small, and the operating knife is more comfortable and convenient to use. The operating knife comprises a knife handle and a knife blade, wherein the knife blade is made of stainless steel, and an acute angled bend cutter is arranged on the front portion of the knife blade. A cutter edge is arranged on the lower portion of the acute angled bend cutter, and another cutter edge is arranged on the lower portion of the knife blade, and the knife handle is arranged on the rear portion of the knife blade. The knife handle is made of plastic, and a pressure-resisting block is arranged at the connector between the rear portion of the knife blade and the knife handle. An extending block is arranged at the connector between the lateral edge of the rear portion of the knife blade and the knife handle. The operating knife has the advantages that the operating knife is simple in structure, the design of the extending block improves the pressure intensity of the cutter edges, and design of the pressure-resisting block enables the contact area of the side face of the rear portion of a knife body to be wider. The operating knife is more comfortable for a doctor to use, and can not injure the hand, is low in production cost, and convenient to operate, and has multiple functions with one knife, and is time-saving and labor-saving.

Description

A kind of scalpel

Technical field

This utility model relates to medical instruments field, relates in particular to a kind of scalpel.

Background technology

The hospital inside and outside scalpel of the doctor of section use comprises blade and handle of a knife, and scalpel all is through autoclaved when each the use.When operation, the doctor clamps two faces about the knife back with thumb and forefinger respectively, withstand the cutter back side edge with middle finger, then middle finger, the third finger, little finger are held hilt and are pressed down the knife back, hold the cutter fulcrum during operation at the cutter trailing flank, so blade pressure are not high enough, holding the cutter fulcrum relatively lags behind, the area of the knife back, cutter trailing flank is very narrow, extremely strangles finger, bad exerting oneself.

Summary of the invention

This utility model provides novel a kind of scalpel for the prior art above shortcomings, has overcome existing scalpel and has held the cutter fulcrum and relatively lag behind, and blade pressure is not high enough, and the knife back, the narrow shortcoming of cutter trailing flank contact surface use more comfort and convenient.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of scalpel, comprise hilt, blade, described blade is made by rustless steel, described blade front portion is provided with the acute angle shape tulwar, and described acute angle shape tulwar bottom is provided with blade, and described blade bottom is provided with blade, described blade rear portion is provided with hilt, described hilt is made of plastics, and described blade rear portion and described hilt junction are provided with withstand voltage, and described blade rear portion side and described hilt junction are provided with extension block.

This utility model beneficial effect: simple in structure, the design of extension block has promoted blade pressure, withstand voltage design makes blade rear portion contact surface become wider, more comfortable when the doctor uses, this patent production cost is low, easy to operate, be equipped with an acute angle shape tulwar in the blade front portion, and is more convenient when operation is used for the pocket knife mouth in operation, one cutter is multiplex, alleviate patient's misery, increased doctor's work efficiency, time saving and energy saving.

Description of drawings

Fig. 1 is scalpel structure schematic diagram described in the utility model.

Among the figure:

The 1-hilt; The 2-blade; 3-acute angle shape tulwar; The 4-blade; 5-is withstand voltage piece; The 6-extension block.

The specific embodiment

The below is described in further detail this utility model with embodiment with reference to the accompanying drawings:

As shown in Figure 1, a kind of scalpel of the present utility model, comprise hilt 1, blade 2, surgical knife is the same with original scalpel, all formed by hilt 1 and blade 2, described blade 2 is made by rustless steel, be provided with blade 4 in blade 2 bottoms, be provided with hilt 1 at blade 2 rear portions, difference is that novel scalpel is provided with acute angle shape tulwar 3 in blade 2 front portions, it is used that acute angle shape tulwar 3 is used for cutting small-sized wound, cuts out a breach that is slightly larger than middle finger at blade 2 rear portion sides, is equipped with extension block 6 in indentation, there, namely be provided with extension block 6 at blade 2 rear portion sides and described hilt 1 junction, extension block 6 is operation Shi doctor's finger position, because extension block 6 is wider, so finger is exerted oneself when making things convenient for the doctor to perform the operation.Be equipped with withstand voltage 5 at blade 2 rear portions and described hilt 1 junction, convenient finger firmly, withstand voltage 5, extension block 6 link together with hilt 1, form the structure of an integral body, described hilt 1 is made of plastics, and the doctor is used more comfortable when operation.

During use, the doctor holds hilt 1, middle finger is placed on above the extension block 6, injury with 4 couples of patients of blade of the acute angle shape tulwar 3 of blade 2 front portions cuts first, and then continue to cut to the edge of a knife position of suitable operation with the blade 4 of blade 2 bottoms, because the design of the acute angle shape tulwar 3 of blade 2 front portions, so be more prone to for some minor cut or wound cutting, and more safe ready is used in the design of withstand voltage 5 and extension block 6.

Claims (1)

1. scalpel, it is characterized in that: comprise hilt, blade, described blade is made by rustless steel, described blade front portion is provided with the acute angle shape tulwar, and described acute angle shape tulwar bottom is provided with blade, and described blade bottom is provided with blade, described blade rear portion is provided with hilt, described hilt is made of plastics, and described blade rear portion and described hilt junction are provided with withstand voltage, and described blade rear portion side and described hilt junction are provided with extension block.
