AI Technical Summary

Technical Problem

Existing surgical cutting and suturing instruments are difficult to operate efficiently and reliably when cutting and suturing tissues, especially due to instability and inconsistency in the coordination of the staple cartridge and anvil and in the staple firing process.

Method used

A surgical cutting and suturing instrument was designed, employing a rapid jaw closure system, a high-load jaw clamping system, and a nail firing system. Combined with a curved platform surface and protrusions extending from it, it ensures a stable fit between the nail cartridge and the anvil, and maintains precise control of the feature structure and firing component through an actuator, achieving reliable nail firing.

Benefits of technology

It improves the stability of the staple cartridge and anvil and the reliability of staple firing, ensuring the efficiency and consistency of the cutting and suturing process and enhancing the operability and controllability of the instrument.
