Description
Technical Field
[0001] The utility model relates to the technical field of high-frequency electrotome pens, and particularly relates to a protection device for a high-frequency electrotome pen. Background Art
[0002] For a high-frequency electrotome pen, the part in contact with the body is concentrated on a small section at the tip of the knife head. For the consideration of preventing cross-infection and other factors, and to avoid the risk of skin burns caused by accidental activation during the operation, some manufacturers are equipped with plastic protective covers for some high-frequency electrotome pens. After the medical staff finishes draping, the protective cover is fixed on the hole towel. After each use, the operator places the electrotome pen into the protective cover and takes it out of the protective cover when using it again, thus avoiding the occurrence of burns around the incision caused by accidental activation.
[0003] When the existing high-frequency electrotome pen protects the electrotome pen head, its protective cover usually has a fixed size. Therefore, when dealing with electrotome pen heads of different lengths, it is not convenient to change the size of the protective cover. For this reason, we propose a protection device for a high-frequency electrotome pen to facilitate the protection of electrotome pen heads of different lengths. Summary of the Utility Model

After the operator turns the threaded rod, the threaded rod pushes the arc-shaped clamping plate to squeeze and fix the tip of the pen rod of the main body of the high-frequency electrotome pen, so as to conveniently connect and fix the sleeve body to the main body of the high-frequency electrotome pen.
[0011] Specifically, an electrotome head is installed at the output end of the main body of the high-frequency electrotome pen.
[0012] By adopting the above technical solution, it is convenient for the main body of the high-frequency electrotome pen to control the electrotome head.
