Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of the repetitive electric scalpel pen with replaceable protective structure, especially to a repetitive electric scalpel pen with replaceable protective structure. BACKGROUND
[0002] The surgical electric scalpel pen is an electric surgical instrument for replacing mechanical surgical knives to cut tissues. It realizes the separation and coagulation of the body tissues by heating the tissues when the high-frequency high-voltage current generated by the tip of the effective electrode contacts the body, thereby achieving the purpose of cutting and hemostasis. In surgery, high-frequency electric scalpel pens are often used. The high-frequency electric scalpel pen with high-frequency high-voltage current can cause the gasification or coagulation of tissues when cutting and coagulating tissues with high impedance. Among them, the electric scalpel pen head will attach some eschar, and blood stains will contact the electric scalpel pen. The doctor needs to clean the electric scalpel pen head or replace the electric scalpel pen to continue the operation, which seriously affects the operation process, and the frequent replacement of the electric scalpel pen has high economic cost. Therefore, a protective structure needs to be used in the use of the electric scalpel pen, such as the utility model patent with the patent number CN220141796U, a repetitive electric scalpel pen with replaceable protective structure.
[0003] However, in the use of the above protective structure, the electric scalpel pen after use will have blood or other tissues on the head, and the medical staff will be easily contaminated by these medical waste during the replacement of the electric scalpel pen head, which will cause unnecessary medical safety hazards, and the existing electric scalpel pen needs to directly contact the blade when replacing the head, which is not easy to replace, causing many inconveniences in use. UTILITY MODEL CONTENT
