Background
The electric scalpel is an important tool widely used in surgical operations for performing electrocoagulation and electrosection, and has the advantages of less bleeding and high efficiency compared with the traditional scalpel, so that the electric scalpel becomes a necessary instrument for many surgeons. However, during the process of cutting separation (electrosection) and/or hemostasis (electrocoagulation) using an electrotome, smoke is often generated, interfering with the surgical field. In addition, blood and debris generated during the procedure can also affect the procedure. To remove such fumes, blood and debris, suction with a suction apparatus and a cleaner is required in synchronization with the electric knife.
Originally, the electric knife and the suction apparatus were separated, but they often took up two hands of the surgeon or required two persons to operate, which made the operation cumbersome, and in addition, the use of a separate suction apparatus made the precise positioning of the operation difficult.
Therefore, there has been invented a surgical dissector which integrates an electric knife and a suction apparatus to simultaneously perform an electric cutting function, an electric coagulation function and a suction function, and which is configured such that the electric knife is provided on a side wall of an end portion of the suction tube and a suction operation is performed simultaneously during a surgical operation, but the dissector has the following problems during use: 1. because the electrotome is fixedly connected with the suction tube, the suction effect is difficult to act on the incision in a short distance, and the cleaning effect is poor, 2, in the use process of the electrotome, partial tissue fragments are often adhered to the electrotome, and the operation is carried out after the fragments need to be cleaned, so that the operation time is prolonged, and the use is inconvenient.
