Embodiment 1

[0034] Such as Figure 1-4 As shown, the suturing device for assisting laparoscopic surgery wound suturing includes a puncture needle 2 and a rod-shaped body 1 that is matched with the endoscope poking hole, and the end of the puncture needle 2 is provided with a clamping port 21 for clamping a suture 3 The bottom of the rod-shaped main body 1 is provided with a peritoneum positioning device 4, and the peritoneum positioning device 4 is provided with a limiting groove 51, and also includes a clamping mechanism 6 and a limiting mechanism 7. The wire mechanism 6 is detachably connected, and the middle part is detachably connected with the limit groove 51. At least one limit mechanism 7 is slidably disposed in the through groove 11 passing through the rod-shaped main body 1. The limit mechanism 7 is provided with at least one Guide hole 71, move the puncture needle 2 along the guide hole 71, the clamping opening 21 enters the limiting groove 51, moves the limiting mechanism 7 alo...

Embodiment 2

[0042] Such as Figure 1-4 As shown, the suturing device for assisting laparoscopic surgery wound suturing in this embodiment has the same structure as that of the embodiment, the difference is that the pull rod assembly 8 includes a guide pull rod 81 and a limit pull rod 82, and one end of the limit pull rod 82 is connected to a limit pull rod. The middle part of the positioning plate 5 is rotatably connected, and the other end is rotatably connected with the inner wall of the rod-shaped main body 1. The guide rod 81 is arranged along the axial direction of the rod-shaped main body 1, and the bottom end is rotatably connected with the limit plate 5. Moving the guide rod 81 can drive the The peritoneal positioning device 4 moves in and / or out of the rod-shaped body 1, and the limiting pull rod 82 is made of flexible material.

[0043] The suturing device for assisting laparoscopic wound suturing in this embodiment preferably adopts a pull rod assembly 8 composed of a guide rod...

Embodiment 3

[0045] Such as Figure 1-4 As shown, the suturing device for assisting laparoscopic surgery wound suturing in this embodiment has the same structure as the embodiment, the difference is that it also includes a control mechanism 9 for controlling the movement of the guide rod 81, and the control mechanism 9 includes a guide The control block 91 connected to the top end of the pull rod 81 is slidably arranged in the rod-shaped body 1, and the control block 91 is provided with a control for controlling the axial movement of the control block 91 along the rod-shaped body 1. handle 92.

[0046] The suturing device for assisting laparoscopic surgery wound suturing in this embodiment, by setting the control mechanism 9, can easily drive the guide rod 81 to move along the axial direction of the rod-shaped main body 1, thereby conveniently controlling the relative position of the two limiting plates 5. turn.

[0047] Preferably, a limit ring 93 is provided on the side wall of the con...

Abstract

The invention relates to the field of medical instruments, in particular to a suture device for assisting a suture of an endoscope surgery wound. The suture device comprises a puncture needle and a rod-shaped body matched with an endoscope hole. The end of the puncture needle is provided with a clamping port for clamping the suture. The bottom of the rod-shaped body is provided with a peritoneal positioning device, and the peritoneal positioning device is provided with a limiting slot. The suture device also comprises a clamping mechanism and a limiting mechanism. The two ends of at least onesuture are detachably connected to the clamping mechanism, and the middle portion of at least one suture is detachably connected to the limiting slot. At least one limiting mechanism is slidably arranged in the through slot penetrating the rod-shaped body. The limiting mechanism is provided with at least one guiding hole, and the puncture needle is moved along the guiding hole. The clamping port enters the limiting slot, and the limiting mechanism is moved along the through slot. The position of the clamping port entering the limiting slot is changed, and the limiting mechanism can be moved according to the thickness of the abdominal cavity wall to change the lead-out position of the suture, so that the wound is sutured more stably and the recovery is faster.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a suturing device for assisting laparoscopic surgery wound suturing. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method. During laparoscopic surgery, the doctor only needs to make a few small holes around the patient's surgical site, and cooperate with the endoscope for examination and treatment, and then In front of the computer screen, the internal condition of the patient can be visualized, and precise surgical operations are performed. It has the characteristics of less trauma, less complications, safety, and quick recovery, which reduces the pain of treatment for the patient, and the scars on the skin after recovery are smaller. [0003] However, because the puncture hole formed by laparoscopic surgery is small and deep, conventional intraoperative puncture needles are not easy to seal the peritoneum and fascia laye...
