The curved and angled design can better adapt to these complex anatomical structures, enabling doctors to operate the grasping forceps more flexibly, reach difficult-to-access areas, and improve the adaptability and success rate of the surgery. Moreover, the curved and angled design can reduce the compression of the suspension laryngoscope on parts such as the lips, front teeth, and tongue body, thereby reducing the risk of damage to these parts during the surgery and the occurrence of postoperative complications.

[0061] In this embodiment, the telescopic rod 10 cooperates with the return spring 9 to ensure that the jaws open and close gently and smoothly, and the return spring 9 assists in rapid rebound. In addition, the double-limiting design of the angle adjustment shaft 13 and the limiting groove 16 avoids angle deviation during the operation and ensures the operation stability.

[0062] In summary, in the present invention, the pliers base 21 is detachably connected to different tools such as the bite and cut scissors 1, the bite and cut forceps 22, and the hook needle 23. When different tools are needed during the surgery, rapid replacement can be achieved, reducing the interruption time of the surgery, helping to improve the surgical efficiency, and further enhancing the accuracy and safety of the surgery. Doctors can quickly switch between the bite and cut scissors 1, the bite and cut forceps 22, and the hook needle 23 as needed during the surgery.

[0063] At the same time, the adjustability of the handle angle enables doctors to adjust the angle of the handle according to personal habits and surgical needs, improving the operation comfort and reducing the fatigue caused by long-term surgery. By adjusting the handle angle, doctors can operate the grasping forceps more naturally, reducing unnecessary movements of the hands and wrists, thereby improving the accuracy and stability of the surgery.
