Abstract

The invention discloses a minimally invasive scalpel for a surgery, which comprises a blade, a scalpel handle and a scalpel rod. One end of the scalpel rod is provided with a groove; the scalpel handle which is formed by connecting a first strip-shaped part and a second strip-shaped part has a rectangular section; and the other end of the first strip-shaped part is fixed in a groove of the scalpel rod. The first strip-shaped part is higher than the second strip-shaped part; and the blade is higher than the second strip-shaped part. A groove region is formed among the second strip-shaped part, the blade and the first-shaped part; and the blade and the first-shaped part are located at the two ends of the second strip-shaped part. The blade is welded at one side face of the front part of the second strip-shaped part; the bottom en face of the blade and the bottom end face of the second strip-shaped part are located in the same plane and have a welding region therebetween; and three spot-welding regions are arranged between the upper end face of the blade and the upper end face of the second strip-shaped part (6). An included angle between the edge of the blade and the length direction of the blade is 79-81 degrees; and the upper part of the edge is provided with a chamfering inclined plane. The scalpel disclosed by the invention is high in accuracy, can improve treatment effect and can reduce tissue damage.

Description

technical field

[0001] The invention relates to the field of medical instruments, in particular to a minimally invasive scalpel for surgery. Background technique

[0002] Minimally invasive surgery is welcomed by patients because of less trauma, less pain and faster recovery. However, due to the limitations of equipment and conditions, surgery has high requirements for doctors. In the prior art, the scalpels used in clinical surgery usually include small needle knife and ordinary scalpel. The small needle knife has a narrow head, and the body of the knife is not strong enough. In addition, the handle is short and violin-shaped, which is not conducive to the adjustment of the direction of the knife head. , In addition, the cutting and separation can not achieve the purpose of treatment; the blade of ordinary scalpel is wide, which will cause great damage to normal tissues, so it is not suitable for minimally invasive surgery. Therefore, how to design a method with a high de...
