Abstract

The invention discloses a thermal energy tool bit. The thermal energy tool bit comprises a first working part and a second working part which are matched with each other, wherein at least one workingsurface is arranged on each of the first working part and the second working part; a heating device is arranged on at least one working surface; and a bulge capable of extruding liquid in tissues outwards is arranged on at least one working surface. A tissue ablation, cutting and fusion system comprises a handle assembly, a shaft assembly, a working part, a circuit system and a power supply. The working part comprises the thermal energy tool bit. The bulge capable of extruding the liquid in the tissues outwards is designed on the thermal energy tool bit, so that when the working surfaces are closed, the liquid in the tissues in a working area can be quickly discharged outwards, the interference of the liquid is reduced, and proteins in the tissues in the working area can be quickly agglutinated and modified under the action of temperature; and during clinical use, the tissue ablation, cutting and fusion effects are better, and the working efficiency is higher.

Description

technical field [0001] The invention relates to an electrosurgical instrument, in particular to the surgical instrument used for tissue ablation, cutting and fusion in surgical operations. Background technique [0002] In surgery, tissue ablation, cutting and fusion are very important tissue processing processes. Among the commonly used tissue ablation, cutting and fusion technologies, electric heating tissue ablation method is one of the important technologies. By heating the tissue, causing Aggregation and modification of proteins to achieve tissue ablation, cutting and fusion processes. Therefore, in the electrical heating tissue ablation method, the core is how to ensure rapid aggregation of proteins and rapid temperature rise. In human tissue, in addition to protein, there are also a large amount of liquid substances, such as blood, interstitial fluid, etc. The existence of these liquid substances has obvious interference on the aggregation and temperature rise of prot...
