Tissue ablation, cutting and merging system

Abstract

The invention relates to a tissue ablation, cutting and merging system. The tissue ablation, cutting and merging system comprises a handle assembly, a shaft assembly, a working part, a circuit systemand a power source, wherein a trigger switch is arranged on a controller of the circuit system; a trigger part is arranged on a trigger; when the trigger moves in the direction facing a gripping handle of a housing until a force limiting mechanism works, the trigger part touches the trigger switch to switch on the trigger switch; and when the trigger moves in the direction away from the gripping handle of the housing, the trigger part is separated from the trigger switch to switch down the trigger switch. According to the tissue ablation, cutting and merging system disclosed by the invention,the trigger switch can only be switched on when the force limiting mechanism works, so that the tissue ablation, cutting and merging system disclosed by the invention can perform tissue ablation, cutting and merging under a set working pressure, the operation effect is more stable, accidental injury which is possibly caused by misoperation and clinical effect differences of vascular occlusion, tissue ablation, tissue cutting and the like caused by different clamping force used by different surgeons are effectively avoided, and the tissue ablation, cutting and merging system is safer and more effective.

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 Modification of proteins to enable tissue ablation, cleavage and fusion processes. [0003] In the tissue ablation, cutting and fusion systems of the prior art, the connection of the circuit usually includes two switches: the power switch and the gear selection switch. When the two are connected at the same time, the circuit is in the connected state, and the electric heating The unit starts to heat up. However, in actual clinical use, when the device is placed aside and not used, the...

Problems solved by technology

However, in actual clinical use, when the device is placed aside and not used, the heating device of the device is in a heating state for a long time due to forgetting to turn off the power switch and gear switch, or misoperation, and the continuous high temperature state of the device, on the one hand, It is easy to cause damage to the equipment. On the other hand, if the equipment is inadvertently in contact with combustibles such as bed sheets and towels in the operating room, it is easy to cause a fire, which has a very obvious safety hazard
