Problems solved by technology

However, only the skin and subcutaneous fat can only be sutured when the small hole is sutured after surgery, while the peritoneum inside the abdominal wall cannot be sutured, and an opening in the peritoneal layer appears, resulting in adhesion of the greater omentum and intestine, and postoperative sequelae
Those skilled in the art are also trying various methods, but this problem has not been properly resolved

Embodiment 1

[0019] Example 2: see Figure 3-Figure 7 , as an improvement of the present invention, the suture assembly includes a suture double needle 7, a hinge rod upper rod 8 and a hinge rod lower rod 9, the hinge rod upper rod 8 and the hinge rod lower rod 9 are symmetrically arranged, and the suture The double needles are symmetrically arranged on both sides of the support rod, the suture double needle 7, the hinge rod upper rod 8, and the hinge rod lower rod 9 can be rotated and adjusted at any angle. Way. Other structures and advantages are exactly the same as those in the embodiment.

Embodiment 2

[0020] Example 3: see Figure 3-Figure 7 , as an improvement of the present invention, the overall suture assembly is an umbrella structure, the diameter after folding is less than 5mm, and the diameter after unfolding is 28-32mm, generally no more than 30mm. This technical solution skillfully sets the suture assembly into an umbrella shape The structure is retractable and folded before the entrance, and it reaches the suture standby state. After opening, the diameter is about 28-32mm, and it is set as a double-needle structure, which is convenient for one operation. The needles and threads exit on both sides, which is convenient for knotting and fixing. The stapler includes a needle-pressing ring handle 11 and a needle-pressing ring groove 6 , and the needle-pressing ring handle 11 and the needle-pressing ring groove 6 are both arranged on a support rod 15 .

Embodiment 3

[0021] Example 4: see Figure 1-Figure 9 , the method of using the puncture hole stapler for minimally invasive surgery, the steps are as follows: 1) After the double needles of the stapler are completely folded, they can enter the abdominal cavity through the inner hole of the abdominal puncture device with a diameter of 5mm. After the stapler enters the abdominal cavity, pinch Tighten the lock 12 of the sliding ring handle, push the sliding ring handle 4, so that the double needles of the suture needle can be unfolded to the position to be sutured; The needle tip of the device passes through the peritoneum, fat layer, muscle layer, and even the epidermis, exposing the needle point and the suture in the needle point space. At this time, pick out the sutures on both sides, return the suture device, tie the sutures, and complete the first suture ;3) Rotate the stapler at a certain angle, repeat the above operation, and perform the second stitch; 4) Repeat the above operation, a...

Abstract

The invention relates to a puncture hole suturing device for minimally invasive surgery. The suturing device comprises a supporting rod, a handle assembly and a suturing assembly. The handle assembly is arranged at one end of the supporting rod, and the suturing assembly is arranged at the other end of the supporting rod. The handle assembly comprises a handle bracket (1), double-side handle rings (2), a needle holding handle (3), a sliding circular ring handle (4) for double needle opening and closing and a sliding circular ring handle lock catch (12), wherein the circular ring handle and the double-side handle rings are arranged on the supporting rod, the sliding circular ring handle lock catch (12) is arranged on the sliding circular ring handle (4), the double-side handle rings (2) are arranged on the two sides of the needle holding handle (3), and the handle bracket (1) is arranged at the end of the supporting rod. According to the technical scheme, a suturing double needle, an upper hinge rod and a lower hinge rod can be rotationally adjusted at any angle, operation is flexible and convenient, and the suturing mode of outward pricking of an interior needle entering the enterocoelia is achieved.

Description

technical field [0001] The invention relates to a stapler, in particular to a minimally invasive surgery puncture hole stapler, which belongs to the technical field of medical instruments. Background technique [0002] In minimally invasive human medical surgery, once a lesion is found in the human body, surgery or resection is required. During the operation, the first thing to use is a puncture device, which is a device that pierces the abdominal wall and provides access to the body cavity for other surgical instruments. A surgical instrument belongs to a minimally invasive surgical instrument. Laparoscopic surgery is a form of minimally invasive surgery widely used at present. During the operation, 3-4 small holes with a diameter of 1 cm are made on the abdominal wall, and the observation mirror and minimally invasive surgical instruments are inserted into the abdominal cavity through the small holes for surgical operations. However, only the skin and subcutaneous fat can...
