Furthermore, the outer side wall of the rotatable handle can be processed with anti-skid wear-resistant lines.

Specifically, as shown in fig. 5, when the doctor performs the operation under the microscope lens, the rotatable handle of the scalpel handle can be inclined at an angle of 0-45 degrees in the vertical direction, and can be rotated and positioned at any angle of 360 degrees in the horizontal direction, so that the handle is ensured not to block the sight. When the bending angle of the rotatable handle needs to be adjusted, the upper locking block is loosened, the angle of the rotatable handle is adjusted, and then the upper locking block is locked.
