Problems solved by technology
The internal structure of the hernia repair stapler used in the current laparoscopic hernia repair surgery adopts a multi-stage gear transmission mechanism, and the transmission is not stable; and the noise is relatively large during the operation of the instrument, and during the transmission process, there are many parts, and the structure and position are relatively small. Complex, so the probability of equipment failure is high; in addition, the cost is high, and it is not easy to repair if a failure occurs

Embodiment Construction
[0035] Below in conjunction with embodiment and Figure 1 to Figure 8 The technical scheme of the present invention is further elaborated.
[0036] This embodiment provides a hernia repair stapler, comprising:
[0037] The proximal end is provided with a housing 2 with a fixed handle 1; a nail feeding tube 3 arranged at the far end of the housing 2; a driving rod 4 penetrating through the nail feeding tube 3 and rotatable relative to the nail feeding tube 3; A plurality of titanium nails 5 on the rod 4; a drive assembly that drives the drive rod 4 to rotate is arranged in the housing 2; a trigger 6 that activates the drive assembly and can rotate relative to the handle;
[0038] The drive assembly includes a motion conversion mechanism 7 and an anti-reverse mechanism 8 .
[0039] The motion conversion mechanism 7 receives the driving force of the trigger 6 to convert the linear motion into a rotary motion, and drives the drive rod to rotate; the anti-reverse mechanism 8 can ...

The invention discloses a hernia repair suture nail device. The hernia repair suture nail device comprises a shell provided with a fixed handle arranged at the near end, a nail delivery tube arranged at the far end of the shell, a driving rod penetrating through the nail delivery tube and capable of rotating relative to the nail delivery tube, multiple titanium nails arranged on the driving rod, a driving assembly arranged in the shell and driving the driving rod to rotate, a start driving assembly and a trigger capable of rotating relative to the handle, wherein the start driving assembly comprises a motion switching mechanism and a reverse rotation preventing mechanism. The motion switching mechanism receives the driving force of the trigger to switch linear motion into rotating motion and drive the driving rod to rotate. The reverse rotation preventing mechanism enables the driving rod not to be affected and prevents the driving rod from rotating reversely when the trigger gives out a reverse driving force. The mode of drive achievement through original multi-stage gear meshing is changed, drive stability is greatly improved, the hernia repair suture nail device is simple in structure, noise is reduced, the probability of fault occurrence is low, and the cost is reduced.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a hernia repair stapler. Background technique [0002] Inguinal hernia is one of the most common diseases in general surgery, and it cannot be cured without surgery. The internal structure of the hernia repair stapler used in the current laparoscopic hernia repair surgery adopts a multi-stage gear transmission mechanism, and the transmission is not stable; and the noise is relatively large during the operation of the instrument, and during the transmission process, there are many parts, and the structure and position are relatively small. Complex, so the probability of equipment failure is high; in addition, the cost is high, and it is not easy to repair if a failure occurs. Contents of the invention [0003] The purpose of the present invention is to provide a hernia repair stapler, which changes the original way of multi-stage gear meshing to realize transmission, greatly ...
