Non-stick electro-coagulation forceps

Abstract

The invention discloses a pair of non-stick electro-coagulation forceps. The forceps comprise two forceps bodies and a tail connector, the forceps bodies are fixedly connected with the tail connector,forceps tips are further fixedly connected to the ends, away from the tail connector, of the forceps bodies, electric conduction and heat conduction channels are laid on the forceps bodies, one end of each electric conduction and heat conduction channel is directly connected with the corresponding forceps tip, and the other end of the electric conduction and heat conduction channel extends to thetail part, away from the corresponding forceps tip, of the corresponding forceps body and used for enabling the electric conduction and heat conduction channel to directly contact with a power wire in the tail connector. The forceps tips and the tail connector are directly switched on through the electric conduction and heat conduction channels, the overall electric conduction and heat conductionperformance of the electro-coagulation forceps is guaranteed, and a non-stick effect of a product is guaranteed.

Description

technical field [0001] The invention relates to the field of electrosurgery for medical instruments, in particular to a non-stick electrocoagulation tweezers. Background technique [0002] Ordinary bipolar electric coagulation forceps used in electrosurgery are easy to stick to tissue during the operation, resulting in poor discharge effect of electric coagulation forceps and affecting the coagulation effect. At the same time, the adhesion of the tissue will also cause tearing of the tissue, resulting in damage to the surrounding tissue of the surgical site, and even secondary bleeding; some surgical operations that require high surgical accuracy and safety require the use of electrocoagulation to stop bleeding and at the same time Bipolar forceps for non-stick tissue coagulation. [0003] At present, a variety of bipolar electrocoagulation tweezers known as "non-stick tissues" have appeared on the market. According to the structural characteristics of the products and the ...

Problems solved by technology

However, the dripping electrocoagulation tweezers has a complex structure, and the dripping water during the electrocoagulation work will affect the surgical field of view, which cannot fully meet the needs of electrosurgery, especially precision operations such as neurosurgery; Electrocoagulation tweezers, this type of electrocoagulation tweezers mainly use non-stick materials to make products to achieve non-stick effects. Currently, well-known brands on the market, such as German Snake and German Sutter, all use silver-based alloys. The tweezers body or tweezers tip are made of materials with excellent electrical and thermal conductivity to ensure that the product has non-stick properties. For example, the patented technology of US20070265619 discloses an electrosurgical electrocoagulation tweezers with tweezers tips made of composite materials. Its main features The tip of the tweezers is made of silver-based alloy material to improve the non-stick effect of the electrocoagulation tweezers

But this kind of product still has some defects, because most of its tweezers are made of hard metals such as stainless steel, whose conductivity is much lower than that of silver-based alloys, which will lead to a decrease in the average conductivity and thermal conductivity of the tweezers, and further It will still affect the non-stick performance of the entire product, especially when the tip of the tweezers is discharged for a long time during the operation, due to the increasing heat, it is not enough to transfer the heat away in a timely manner simply by relying on a small amount of silver-based metal at the tip of the tweezers. At this time, there will be a decrease in non-stick performance.
