Thermal coagulation haemostatic surgical scissors

Abstract

The invention discloses a pair of thermal coagulation haemostatic surgical scissors. The pair of thermal coagulation haemostatic surgical scissors comprises a first scissor component and a second scissor component; the first scissor component and the second scissor component are both composed of a scissor part and a scissor handle part; each scissor part is internally provided with a heating cavity used for containing a heating unit, the heating units are assembled in the heating cavities of the first and second scissor components and used for heating the scissor parts, and the first scissor component and the second scissor component are connected through a shaft; the surface of each scissor part is provided with an anti-adhesion structure composed of periodically distributed convex parts or / and convex parts, the smooth surfaces of the scissor parts become rough surfaces with the micron-dimension roughness, the surface performance of the scissor parts is changed, cut human body tissue and the surfaces of the scissor parts form a composite contact surface, the contact area is greatly reduced, and the scissor parts of the surgical scissors do not adhere to the human body tissue making contact with the scissor parts during operations. The anti-adhesion structures take the place of polytetrafluoroethylene chemical anti-sticking coatings, adhesion is prevented, no toxic substances are released in the use process, healing of the cut tissue is not affected, and the safety of the operations is improved.

Description

technical field [0001] The invention relates to an electrothermal surgical knife, in particular to a thermocoagulation hemostatic surgical scissors with an anti-adhesion structure on the surface, which belongs to the field of medical instruments. Background technique [0002] Surgical scissors are medical instruments commonly used in surgical operations, and are used to cut human tissues such as epidermal tissue and soft tissue of patients. Ordinary surgical scissors tend to bleed when cutting human tissue. Bleeding will interfere with the surgeon's field of vision, prolong the operation time and reduce the accuracy of the operation. In order to solve the problem of intraoperative bleeding, a Chinese patent application with application number 201210062396.3 appeared, which discloses a kind of electrothermal surgical scissors. The above-mentioned surgical scissors have the effect of thermal coagulation, which reduces intraoperative bleeding and improves surgical efficiency. ...

AI Technical Summary

Problems solved by technology

The thermal conductivity of polytetrafluoroethylene is much smaller than that of metal materials. The anti-adhesion coating leads to low heat transfer efficiency of surgical scissors, which will lead to insufficient hemostasis. In order to strengthen coagulation, it is necessary to increase the coagulation temperature

When the temperature of surgical scissors increases, on the one hand, it will cause greater damage to the sheared tissue, on the other hand, it will cause polytetrafluoroethylene to release toxic gas at high temperature, damage the sheared human tissue, affect postoperative healing, and Pollution of the operating room environment
