A surgical automatic stapler based on a robotic arm

Abstract

The invention discloses an automatic surgical stapler based on a mechanical arm, which includes a mechanical arm, a fixed seat, an electric push rod A, an adjustment seat, a stepping motor, a driving gear, a rack plate, a positioning block, a steering gear, B electric push rod, puncture push rod, B stepping motor, rotating shaft, rotating frame, and elastic clamping cover. Firstly, the stepping motor can rotate the surgical suture needle 180°, and cooperate with the front and rear two-way mechanism, and then realize the suture needle. Second, through the elastic clamping mechanism, not only the clamping and fixing of the suture needle can be achieved, but also because of the elastic method, it is also convenient for subsequent needle insertion operations and expands clinical practicability. Finally, through the electric push rod and steering gear With the combined effect, while taking into account the multi-position adjustment to meet the suture of different surgical sites, it also improves the puncture accuracy and stability of the needle. At the same time, with the mechanical arm, it can precisely control the needle insertion angle, position and depth, etc., greatly enhancing the puncture of surgical needles Backstitch stability and security.

Description

technical field [0001] The invention relates to the technical field of surgical suturing instruments, in particular to an automatic surgical stapler based on a mechanical arm. Background technique [0002] Most of the current surgical operations need to suture the wound. Most of the current surgical suturing instruments are simple in structure. One is a single needle structure that requires medical staff to suture manually, and the other is an auxiliary suturing structure. No matter what kind of suturing equipment And suturing mode, suturing efficiency is all relatively low, has a strong impact on the suturing process of operation. [0003] According to the above, although there are some auxiliary suturing instruments on the market, for example: Chinese patent CN201280041937.2, a surgical suturing instrument for open and / or endoscopic surgery, which is configured to The double-ended surgical needle is passed backward and forward between the jaw member and the second jaw mem...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a surgical automatic suture device based on a robotic arm to solve the problem that the current clinical operation cannot achieve good automatic suture, so it not only increases the difficulty of the operation, but also increases the burden on doctors.
