[0002] In monopolar mode, a complete circuit is used to cut and coagulate tissue. The circuit is composed of a high-frequency generator in the high-frequency electrosurgical unit, a patient plate, connecting wires and electrodes. When used with a laparoscope, different blade accessories can be selected according to actual conditions. In actual use, the connection between the electrosurgical unit head and the electrosurgical unit host is completed by the "blade head connecting wire".

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0023] See also Figure 1-Figure 6As shown, the utility model provides an electric knife connection structure with an anti-loosening function, including a high-frequency knife head access end 1, an arc-shaped groove 5 is provided on the outer side of the high-frequency knife head access end 1. In actual application, the arc-shaped groove 5 is used to facilitate the application of force on the high-frequency knife head access end 1, and a female head 2 for plugging in a male head 6 is provided at the end of the high-frequency knife head access end 1, and a bolt structure 4 for tightening and abutting the male head 6 therein is provided on the female head 2.
[0024] The female head 2 is provided with a threaded sleeve 3, a socket 201 for plugging the male head 6 is formed in the female head 2, a metal sleeve 202 is provided in the socket 201, and the threaded hole in the threaded sleeve 3 is connected to the socket 201. The female head 2 and the threaded sleeve 3 are integrally formed in a T shape. The female head 2 is an insulating layer.
[0025] See the instruction manual Figure 4 and 6 As shown, the bolt structure 4 includes a screw rod 402 threadedly connected to the threaded sleeve 3, one end of the screw rod 402 is fixedly connected to a terminal 401, a cross groove 403 is provided on the terminal 401, and an anti-skid pattern is provided on the outer side of the terminal 401. The bolt structure 4 is made of non-metallic materials. For example, the bolt structure 4 uses nylon bolts, which play an insulating role to prevent accidental electric shock. An anti-skid pressure pad 404 is provided at the head end where the screw rod 402 abuts against the male head 6. In practical applications, the anti-skid pressure pad 404 abuts against the male head 6 and can also play an anti-skid role.
[0026] Working principle:
[0027] During use, when the male connector 6 is inserted into the socket 201 in the female connector 2, the male connector 6 adopts a banana head plug. When the spring piece on the outer wall of the male connector 6 is inserted into the socket 201, it is squeezed by the inner wall of the socket 201, so that the spring piece on the outer wall of the male connector 6 is deformed, thereby achieving preliminary locking of the male connector 6. At this time, the bolt structure 4 rotates in the threaded sleeve 3, so that the end of the screw rod 402 abuts and presses the outer wall of the male connector 6, thereby again pressing and deforming the spring piece on the outer wall of the male connector 6. Under the secondary deformation, the bolt structure 4 can realize locking of the male connector 6 in the female connector 2, thereby preventing the male connector 6 from loosening in the female connector 2.
[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
