Abstract
Description
Technical Field
[0001] This utility model relates to an active monopolar electrocoagulation forceps, belonging to the field of medical devices. Background Technology
[0002] Active instruments are generally divided into two types: bipolar and monopolar. The main function of bipolar instruments is to perform high-temperature carbonization of lesion tissue while in a clamping state (such as bipolar electrocoagulation forceps), while the main function of monopolar instruments is to perform contact high-temperature carbonization of the lesion tissue surface (such as electric rods, electric hooks, electric shovels, etc.). In other words, when using bipolar active instruments for high-temperature carbonization, the lesion tissue needs to be clamped, while when using monopolar active instruments for high-temperature carbonization, it needs to be in contact with the lesion tissue.
