[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: Pressing the button releases the disassembly slot, allowing the forceps to retract. The spring automatically returns to its original position. The forceps and inner rod detach from the handle via the disassembly device, and the inner rod can then be separated from the forceps. Pushing the inner rod forward and rotating it 90° disengages the fixing block from the inner rod's fixing slot, allows for thorough cleaning and disinfection of the inner rod and the right-angle separation forceps head. The cooperation between the forceps and the rotating wheel expands the clamping and separation range. The flushing connector faces vertically downwards to avoid obstructing the view of the upper part of the right-angle separation forceps head, thus preventing obstruction of the doctor's operation. The right-angle separation forceps head is designed for precise operation in confined spaces, facilitating the surgical procedure.
