Description

Technical Field

[0001] The invention relates to the technical field of scalpels, in particular to a scalpel and a method for disassembling a blade thereof. Background Art

[0002] The scalpel includes a handle and a blade connected to the handle. After the operation is completed, the scalpel needs to be cleaned. When cleaning, the blade and the handle need to be separated. In the prior art, the blade and the handle are separated in that the medical staff holds the clamp with one hand and the handle with the other hand, and then removes the blade with the clamp. During the removal process, the clamp and the blade are easy to slip off, and it is also easy to cause the blade to fly off. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In order to solve the above problems in the prior art, the present invention provides a scalpel and a method for disassembling a blade thereof, which facilitates installation and disassembly of the blade body and can disassemble the blade without contact, without causing occupational exposure.

[0005] (II) Technical solution

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0007] A surgical knife comprises a handle body and a blade body, wherein a mounting block is fixedly arranged at one end of the left side of the handle body, the blade body is detachably mounted on the mounting block, the mounting block is provided with a slot used in conjunction with the blade body, the mounting block inner cavity is provided with a clamping mechanism, the clamping mechanism comprises a groove provided in the mounting block, a rotating rod symmetrically installed in the groove, a convex block on one side of the rotating rod close to the inner cavity of the groove, a pressing block and a spring, the pressing block protrudes from the mounting block at one end away from the groove, and a clamping slot used in conjunction with the convex block is provided at the side wall of the blade body. The blade body is convenient to install and remove, and the blade can be removed without contact, without causing occupational exposure.

[0008] Preferably, the blade body comprises a cutting portion and a connecting portion, and the slot is arranged on the connecting portion.

[0009] Preferably, an anti-slip groove is provided on the knife handle.

[0010] Preferably, the inner cavity of the groove is also provided with a stop block for use with the blade body.

[0011] The method for disassembling the blade of the scalpel is as follows: the palm of the hand is on the handle body, one end of the blade body is tilted downward, and the thumb and index finger are used to press the pressing blocks on both sides of the mounting block. The pressing blocks drive the rotating rod to overcome the spring and rotate, the protrusion is separated from the slot, and the blade body falls off from the mounting block due to its own gravity.

[0012] (III) Beneficial effects

[0013] The present invention provides a scalpel and a method for disassembling a blade thereof, which have the following beneficial effects:

[0014] (1) When installing or removing the blade body, you only need to press the pressing block, which is very convenient.

[0015] (2) The blade can be removed without contact. Just press the pressing block and the blade body will fall off due to its own gravity, which will not cause occupational exposure. BRIEF DESCRIPTION OF THE DRAWINGS
