Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a box-type high-frequency electrocautery device. Background Technology

[0002] The box-type high-frequency electrocautery device is a cosmetic medical device that uses high-frequency current to precisely burn and cut biological tissues. The device typically consists of a main unit, a foot switch, a handle, and connecting cables. The main unit is designed in a box shape. Its working principle is to generate high-frequency current through a high-frequency generator. When the current passes through human tissue, heat is generated due to the resistance, thereby heating, coagulating, or cutting the tissue. This can effectively reduce surgical bleeding, shorten surgical time, and improve surgical results, making it an indispensable piece of equipment in modern operating rooms.
