Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical knife heads, in particular to a gynecological surgical knife head combining a mechanical scissors and bipolar electrocoagulation. Background Art
[0002] High-frequency electrosurgical integrated surgical systems are widely used for soft tissue resection, coagulation, and vascular tissue bundle closure in surgical operations. Currently, there are a variety of high-frequency generators on the market, with relatively single functional modes, low integration levels, and few types of supporting execution instruments.
[0003] Monopolar cutting uses high-frequency current to conduct through a surgical instrument (such as an electrosurgical knife) to the target tissue to achieve the purposes of cutting and coagulation. Working principle: The current conducts from the electrosurgical knife to the tissue and then returns to a grounding plate placed on the patient's body through the patient's body. The current path is relatively long and involves most of the patient's body.
[0004] Bipolar coagulation uses two electrodes, which are usually located at two ends of the same instrument, to clamp and coagulate the target tissue. Working principle: The current conducts through the clamped tissue between the two electrodes. Since the current path is relatively short and only passes through the clamped tissue part, the surrounding tissue is less affected.
[0005] How to effectively apply monopolar cutting and bipolar coagulation on the same execution instrument is an urgent problem to be solved in the current market. Summary of the Invention
