Embodiment 1

[0031] Such as Figure 1-4 As shown, the laparoscopic poking stapler for surgical operations includes a puncture needle 1 and a support rod 2 that is matched with the laparoscopic poking hole. The end of the puncture needle 1 is provided with a clamping port 11 for clamping a suture 7, The support rod 2 is provided with a puncture hole 21 matched with the puncture needle 1, and the support rod 2 is also provided with a peritoneum positioning device 3, and the peritoneum positioning device 3 includes a sleeve sleeved on the support rod 2. The pipe 4 and the support mechanism 5, the support mechanism 5 includes at least two link assemblies 51, each link assembly 51 includes a first link segment 511 and a second link segment 512 that are rotatably connected to each other, so The top of the first link segment 511 is rotatably connected to the bottom of the sleeve 4, the bottom of the second link segment 512 is rotatably connected to the support rod 2, and the end of the first link...

Embodiment 2

[0042] Such as Figure 1-5 As shown, the surgical endoscopic poker stapler of this embodiment has the same structure as that of Embodiment 1, the difference is that it also includes a third link segment 513, which is detachably arranged Between the first connecting rod segment 511 and the second connecting rod segment 512, the third connecting rod segment 513 is respectively rotatably connected to the first connecting rod segment 511 and the second connecting rod segment 512. The third connecting rod segments 513 are made of flexible materials, and each of the third connecting rod segments 513 is provided with at least one clamping groove 6 .

[0043] In the endoscopic poking stapler for surgery in this embodiment, a third connecting rod segment 513 made of a flexible material is arranged between the two connecting rod segments. On the one hand, the softer third connecting rod The segment 513 is in contact with the side wall of the wound to avoid damage to the side wall of th...

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to an endoscope puncture stapler for surgery. The stapler comprises a puncture needle and a support rod; a clamping opening used for clamping a suture is formed in the end of the puncture needle, the support rod is provided with a puncture hole cooperating with the puncture needle, a peritoneum positioning device is arranged on the support rod and comprises a sleeve sleeving the support rod and a support mechanism, the support mechanism comprises at least two connecting rod assemblies, each connecting rod assembly comprises at least two connecting sections rotationally connected with each other, a clamping groove used for clamping the suture is arranged on the joint of the two adjacent connecting sections, the sleeve slides along the support rod, the two adjacent connecting sections rotate relatively, the vertical distance between the clamping groove and the support rod is changed, positioning is conducted on the outermost side edge of the support mechanism, tissue on the two sides of a wound can be sewn layer by layer, the sewing effect is good, and the application range of the stapler is expanded.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laparoscopic poking stapler for surgical operations. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method, mainly including pneumoperitoneum laparoscopic surgery and pneumoperitoneum-free laparoscopic surgery. During laparoscopic surgery, doctors only need to open a few The small hole, combined with the endoscope for inspection and treatment, can visually observe the patient's internal conditions in front of the computer screen, and perform precise surgical operations. It has the characteristics of less trauma, fewer complications, safety, and quick recovery. [0003] However, because the laparoscopic puncture hole formed by laparoscopic surgery is small and deep, it is difficult for conventional intraoperative puncture needles to seal the peritoneum and fascia layer close to the inner wall of the abdominal cavity, so ge...
