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. ...

Examples

Embodiment approach

[0038] As an embodiment of the present invention, a kind of thermocoagulation hemostatic surgical scissors, such as figure 1 As shown, a first scissor element 100 and a second scissor element 100 are included, as well as a first heating unit 130 and a second heating unit 130 . The heating unit 130 is elongated, such as figure 1 and figure 2 As shown, from one side to the other side are the electric insulating layer 132, the electric heating element 131, and the electric insulating layer 132 in sequence. electrical insulation. The electric heating element 131 is a thick-film electric heating element, which can be understood as an elongated thin sheet. The electric heating element 131 can be printed on the electrical insulating layer 132 by using a screen printing process, such as figure 2As shown, the electric heating element 131 presents a meandering distribution on the electrical insulating layer 132, and is heated uniformly, so that the temperature distribution outside ...
