Problems solved by technology

[0002] The existing non-stick bipolar electrocoagulation tweezers, in order to reduce the adhesion between the tissue and the tweezers during electrocoagulation, the clamping surface of the tweezers is extremely smooth and mirror-like, so that when clamping tissues, dough sheets, gelatin sponges, thread ends, etc. It is easy to slip and cannot be clamped effectively, so that multiple clamping operations are required, and even the toothed tweezers have to be replaced to achieve the clamping purpose

Embodiment Construction

[0014] see figure 1 a, toothed non-stick bipolar electrocoagulation tweezers of the present invention is characterized in that there are clamping teeth behind the coagulation surface to improve the reliability of the tweezers when clamping tissues and objects.

[0015] The clamping teeth can be arranged vertically or horizontally, especially if the vertical arrangement is adopted, it is beneficial for the perfusate to flow from the root of the tweezers along the handle of the tweezers to the electrocoagulation surface of the tip of the tweezers.

[0016] The toothed non-stick bipolar electrocoagulation tweezers of the present invention is characterized in that: except the electrocoagulation part (daodian section shown in the figure) at the front end of the tweezers conducts electricity, the other parts of the tweezers, including the surface of the clamping teeth, are tightly insulated, Even when clamping an excellent electrical conductor, the tweezers on both sides cannot prod...

Abstract

The invention discloses a pair of toothed non-sticky bipolar electrocoagulation forceps, which is characterized in that longitudinally or transversely arranged clamping teeth are arranged behind an electrocoagulation surface, wherein the clamping teeth are mutually folded but are not engaged; when the electrode surfaces of the forceps are fully closed, a gap is still reserved between the clamping teeth on the two sides; and except that the electrocoagulation part at the front end of the forceps is conductive, the other parts of forceps handles, including the surfaces of the clamping teeth, are strictly insulated. The clamping teeth can be made of other metal or non-metal materials with higher mechanical strength and are integrally adhered to the body of the forceps through an adhesive.

Description

technical field [0001] The invention relates to a medical instrument, which is a kind of surgical instrument, which is used for electrocoagulation and hemostasis of wounds of patients, and implements effective clamping. Background technique [0002] The existing non-stick bipolar electrocoagulation tweezers, in order to reduce the adhesion between the tissue and the tweezers during electrocoagulation, the clamping surface of the tweezers is extremely smooth and mirror-like, so that when clamping tissues, dough sheets, gelatin sponges, thread ends, etc. It is easy to slip and cannot be clamped effectively, so that multiple clamping operations are required, and even the toothed tweezers have to be replaced to achieve the clamping purpose. [0003] The present invention is to solve the problems existing in the existing non-stick bipolar electric coagulation forceps, and proposes a technical solution to improve the clamping efficiency, reduce the replacement of instruments durin...
