The invention discloses a bendable and telescopic medical surgical electric knife, which comprises an electric knife body, the end of the electric knife body of the telescopic assembly, and the end of the electric knife handle extending along its circumferential direction with a limiting groove. The sleeve is sleeved in the limiting groove, and a through hole is opened in the middle of the handle of the electric knife. One side of the sleeve is provided with a push platform, and the sleeve is located on the push platform. Both sides are provided with a permanent magnet 1, the upper and lower sides of the through hole are provided with a permanent magnet 2, the middle part of the limit ring 1 is provided with a pressure rod hole of a bending assembly, and one end of the pressure rod extends to the In the pressure rod hole, one end of the pressure rod is fixedly connected to the pressure rod block, the other end of the pressure rod is fixedly connected to the fixed block, and the spring is sleeved on the pressure rod and located on the fixed between the block and the outer surface of the limit ring one. The invention prevents patients and doctors from being accidentally touched during operation, has higher safety, and has a larger cutting surface.
Description
technical field [0001] The invention relates to a medical device, in particular to a bendable and telescopic medical surgical electric knife. Background technique [0002] Medical surgical electric knife is a medical device used for biological tissue cutting, blood coagulation or both. It can be widely used in surgical operations, including general surgery, brain surgery, heart, etc. When the medical surgical electric knife is used, Use high-frequency current to make the head of the medical surgical electric knife form a local high temperature state, and then perform operations such as cutting and coagulating the tissue. Existing medical surgical electrosurgical pens usually include a handle and electrodes. The electrodes are fixedly installed on the handle and electrically connected to an external high-frequency generator. The handle is provided with a button for controlling the working mode of the electrodes. Since the entire electrode of the surgical electrosurgical knif...
