Description

Technical Field

[0001] The present invention relates to the technical field of electrosurgical pens, and specifically to a surgical electrosurgical pen with a wire harness fixing mechanism. Background Technique

[0002] An electrosurgical pen is a relatively common medical device used in surgeries. The main functions of the electrosurgical pen are tissue electrocautery and electrocoagulation hemostasis. It usually includes a pen body, a functional tube arranged at the front end of the pen body, a circuit board system arranged inside the pen body and electrically connected to the functional tube, and two buttons arranged on the outer surface of the pen body to control the circuit board system. One button controls the functional tube of the electrosurgical pen to perform cutting operations, and one button is used to control the functional tube of the electrosurgical pen to perform coagulation operations.

[0003] After retrieval, it is found that a typical electrosurgical pen in the prior art is, for example, the one with the publication number CN213156386U, a medical electrosurgical pen, which includes a knife head, a copper nozzle, a power cord, and a hollow housing. The rear end of the knife head extends into the housing and is connected to the copper nozzle. One end of the power cord extends into the housing and is connected to the copper nozzle. It also includes a knife sheath, and the knife sheath is connected to the knife head through a snap mechanism. When the knife sheath is connected to the knife head, the front end of the knife head is hidden inside the knife sheath. The medical electrosurgical pen proposed by the present utility model connects the knife sheath and the knife head through a snap mechanism, and the knife sheath is not likely to accidentally fall off the knife head and get lost when not in use.

[0004] In summary, when the existing electrosurgical pen is in use, due to the relatively long length of the power cord and the lack of positioning and fixing of it during the surgery, the power cord is likely to interfere with the operation of the electrosurgical pen, causing inconvenience to medical staff during treatment. Secondly, the length of the existing electrosurgical pen is fixed and cannot be adjusted according to the depth of the surgical site, resulting in the need to replace the corresponding length of the tool during the surgery, prolonging the surgery time and increasing the surgical risk. In view of the above problems, it is necessary to improve the existing equipment. Summary of the Invention
