Detailed Implementation

[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0025] Example 1

[0026] like Figs. 1 to 3 As shown, this embodiment designs a fascia suturing assembly, including components such as a puncture cannula 1 and a suture needle 2.

[0027] The puncture cannula 1 includes a handle 11 and a body 12. The body 12 is connected to the lower end of the handle 11 and is used to insert into the wound to be sutured. Guide holes are inclinedly arranged on both sides of the handle 11, with the angle between the guide holes and the axial direction of the body 12 being 15°-30°. Upper needle holes 121 are provided on the upper left and right sides of the body 12, and lower needle holes 122 are provided on the lower left and right sides of the body 12. The guide hole on the left, the upper needle hole 121 on the left, and the lower needle hole 122 on the right are all on the same straight line. Silicone can be used to seal the upper needle holes 121 and lower needle holes 122, thereby achieving a seal.

[0028] The guide hole includes an enlarged section 112 and a straight section 111 that are interconnected. The small end of the enlarged section 112 is connected to the upper oblique end of the straight section 111, and the large end of the enlarged section 112 is open to facilitate the insertion of the suture needle 2. Since the enlarged section 112 of the guide hole adopts a trumpet-shaped structure, the suture needle 2 can enter the guide hole more easily.

[0029] The tip of the suture needle 2 is provided with a clamp or hook that can fix the suture. When the tip of the suture needle 2 can be inserted from the guide hole, extended from the lower needle hole 122 and puncture the fascia layer, it can drive the suture through the fascia layer, thereby sending the suture into the abdominal cavity or pulling it out from the abdominal cavity.

[0030] The lower end of the tube 12 is obliquely shaped to facilitate insertion of the tube 12 into the wound.

[0031] The suture needle 2 comprises a pressing handle 21, a hand handle 22 and a needle tube 25. The pressing handle 21 is cross-shaped and is connected to the hand handle 22 in an extendable manner. The needle tube 25 is fixed to the lower end of the hand handle 22 and can puncture the fascia layer when passing through the lower needle hole 122. The collet or hook is controlled by the hand handle 22 to extend or retract the needle tube 25 to operate the suture line.

[0032] The diameter of the narrowest part of the guide hole is greater than the outer diameter of the needle tube 25, so as to ensure the smooth insertion of the needle tube 25.

[0033] The pressing handle 21 is internally provided with a compression spring 23, one end of the compression spring 23 abuts against the hand handle 22, and the other end of the compression spring 23 abuts against the pressing handle 21 to reset the pressing handle 21.

[0034] The pressing handle 21 and the collet or collet are provided with a connecting column 24, and the pressing handle 21 pushes or pulls the U-shaped collet 26 out of or into the needle tube 25 through the connecting column 24.

[0035] The collet adopts a U-shaped collet 26, and the bending part of the U-shaped collet 26 has elasticity, so that the U-shaped collet 26 can automatically open when extending out of the needle tube 25, thereby loosening the suture line, and when the U-shaped collet 26 retracts into the needle tube 25, the U-shaped collet 26 can be closed due to the extrusion of the needle tube 25, thereby clamping the suture line.

[0036] When performing laparoscopic surgery, the puncture sleeve 1 in this embodiment can be used as the puncture sleeve 1 in the patent number CN212592333 U, the patent name is a puncture sleeve 1 and a puncture device provided with the puncture sleeve 1. During laparoscopic surgery, the upper needle hole 121 and the lower needle hole 122 can be blocked by silicone, and the insertion depth of the tube body can be controlled, so that the upper needle hole 121 is blocked by the human skin to avoid air leakage at the upper needle hole 121 and the lower needle hole 122.

[0037] When performing fascia suture surgery, the puncture sleeve 1 is still retained at the wound, the suture needle 2 clamps the suture line, the tip of the suture needle 2 passes through the left guide hole, the left upper needle hole 121, the right lower needle hole 122 in sequence, so that the suture line passes through the fascia layer and is sent into the abdominal cavity, and then the suture line is loosened; after the suture needle 2 is taken out, the tip of the suture needle 2 passes through the right guide hole, the right upper needle hole 121, the left lower needle hole 122 in sequence, and punctures the abdominal cavity through the fascia layer, so as to clamp the suture line in the abdominal cavity. When cooperating with other tools, the thread end of the suture line is clamped and fixed by the suture needle 2 again, the suture needle 2 can be extracted, so as to lead the suture line out of the body again, so as to facilitate the medical staff to knot, and realize the wound suture of the fascia layer.

[0038] The above examples are merely intended for the purpose of illustration and are not intended to limit the embodiments; all the embodiments are not required to be enumerated here. The obvious changes or modifications derived therefrom are still within the protection scope of the present technology.
