Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to the puncture cone device of a disposable abdominal wall puncture and suturing device. Background Technology

[0002] Currently, when performing minimally invasive laparoscopic surgery, a puncture suture device is often required. However, due to the need for puncture suturing, the tip of the suture hook is a sharp needle-like structure. During the process of the suture hook entering the puncture suture device, sometimes the tip of the suture hook cuts the guide hole wall and brings the cut debris into the body, which hinders the completion of the operation and may even affect the patient's recovery in severe cases.

[0003] The current puncture and suturing device is not well-designed, which affects the surgical outcome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a puncture cone device for a disposable abdominal wall puncture and suturing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the puncture cone device of the disposable abdominal wall puncture suture device includes a puncture cone, a release switch, a puncture cone seat, a pressure key, a puncture auxiliary ring, and a puncture cone guide hole.

[0006] The upper end of the puncture cone is provided with a puncture cone mounting seat, which is installed between the puncture cannula device and the release switch. The release switch is provided with buckles at both ends, which are fixedly connected to the slots of the positioning guide cover to clamp the puncture cone mounting seat in the middle. The puncture cone seat is installed on the release switch and fits tightly with it. The pressure key is installed in the reserved slot of the puncture cone seat. The pressure key is provided with cylindrical protrusions on both sides and is inserted into the pressure key reserved slot of the puncture cone mounting seat.

[0007] The lower part of the puncture cone has two puncture cone guide holes for threading and hooking the suture. The two puncture cone guide holes are distributed in a crisscross pattern. The auxiliary ring is a symmetrical oblique cylindrical stainless steel ring. The outer wall of the auxiliary ring fits tightly against the inner wall of the puncture cone guide hole, and its inner wall is smooth and without marks. The puncture cone is inserted into the puncture cannula device of a disposable abdominal wall puncture and suturing device.

[0008] The lower part of the puncture cone has symmetrically distributed puncture cone guide holes for threading and hooking the line.

[0009] Each of the two puncture cone guide holes is equipped with a puncture auxiliary ring, which is a stainless steel symmetrical oblique cylindrical ring. Its outer wall is in close contact with the inner wall of the puncture cone guide hole, which can effectively prevent the thread hook from cutting the inner wall of the puncture cone guide hole during puncture, thus preventing debris from entering the patient's body.

[0010] The outer port of the puncture auxiliary ring is provided with an auxiliary ring guide arc, which helps to guide the threading hook into the suture channel of the puncture cone device during abdominal wall layer suturing surgery.

[0011] The lower end of the puncture cone is equipped with a puncture cone head, and there are auxiliary puncture cone blades on both sides to facilitate puncture and establish a surgical channel.

[0012] This utility model's disposable abdominal wall puncture suture device features a rationally designed and easy-to-use puncture cone device. The inclusion of a puncture auxiliary ring facilitates the entry and exit of the suture hook, effectively preventing the suture hook from cutting the inner wall of the puncture cone guide hole during puncture, thus avoiding the risk of debris entering the patient's body. It also serves as a guide, eliminating the need for repeated adjustments to the suture hook's puncture angle and improving surgical efficiency. The end of the puncture auxiliary ring where the suture hook enters is chamfered, helping the suture hook to enter the puncture cone device faster and more accurately. Attached Figure Description
