Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to a surgical electrosurgical unit with supplemental lighting and length adjustment functions. Background Technology

[0002] The working principle of an electrocautery cutter (electrosurgical knife) is that a high-frequency generator produces a high-frequency current, which is conducted to the surgical site through electrodes. The current causes the water in the tissue to evaporate rapidly and the cells to rupture, thereby achieving the cutting effect. At the same time, the high-frequency current causes the proteins in the tissue to coagulate, thereby sealing blood vessels and achieving the purpose of blood clotting.

[0003] Current surgical electrosurgical units have a fixed blade length. When the blade length is long, the operating precision of the blade is reduced and the operation becomes more difficult. When the blade length is short, it is difficult to operate on deeper wounds. Thus, it is difficult to flexibly adjust the length of the electrosurgical unit during use.

[0004] In view of this, this utility model proposes a surgical electrosurgical unit with supplemental lighting and length adjustment functions to solve this problem. Utility Model Content
