Background
Electrotomes are an important tool for use in a wide variety of surgical procedures for performing electrocoagulation and electrotomes, and have the advantage of less bleeding and high efficiency compared to conventional scalpels, and thus have become a necessary instrument for many surgeons. However, smoke is often generated during cutting separation (electrotome) and/or hemostasis (electrocoagulation) with an electrotome, interfering with the surgical field. In addition, blood and debris generated during surgery can also affect the procedure. To remove such fumes, blood and debris, it is necessary to use an aspirator and a cleaner to simultaneously perform suction or flush cleaning following an electric knife.
Initially, the scalpels and the aspirator were separate, but this often took up both hands of the surgeon or required two persons to operate, which caused problems with the procedure, and in addition, the use of separate aspirators caused difficulties in the precise positioning of the procedure.
Therefore, there have been invented surgical dissectors which integrate an electrotome and an aspirator to have electric cutting, electric coagulation and aspiration functions at the same time, and there are mainly two kinds of existing surgical dissectors, one is that the electrotome is directly arranged on an adsorption tube, and cleaning is performed by negative pressure formed at the adsorption tube while the electrotome is cut, and the dissectors have the problems that the position of the electrotome is difficult to adjust in the surgical process to ensure a good smoke cleaning effect due to the fixed relative position of the electrotome and the adsorption tube;
the second is that the electric knife is arranged inside the cleaning tube, and the relative position of the electric knife and the adsorption tube can be adjusted through the offset mechanism, so that the electric knife arranged inside the cleaning tube cannot rotate, and therefore, when the electric knife with different angles is required to be used for probing operation such as scraping, pushing and peeling, the relative position of the electric knife and a doctor hand (namely, the doctor needs to rotate the electric knife to a proper position and then scrape, pushing and peeling operation) needs to be adjusted, and the operation of the operation dissector can drive equipment such as smoking, flushing and the like through the pipeline, so that the pipeline offset can be driven during actual use, the operation is influenced, the operation is inconvenient, meanwhile, the operation is inconvenient to be performed according to piezoelectric coagulation and electric incision after the position adjustment of the palm of the doctor and the dissector, and the operation is also influenced.
