Description

Technical Field

[0001] This utility model relates to the medical field, and more specifically, to a high ligation device for inguinal oblique hernia sac. Background Technology

[0002] Currently, the most commonly used technique is high ligation of the hernial sac in pediatric inguinal hernia using a double-port laparoscopic approach. After completing the preperitoneal purse-string suture of the outer half of the internal inguinal ring using a suture needle with a suture, it is then combined with a hook needle to complete the preperitoneal purse-string suture of the inner half of the internal inguinal ring, assisting the hook needle in leading the suture out of the body.

[0003] However, in actual use, the single-port method requires a puncture needle that is inserted vertically and then circumferentially around the internal hernia opening in a plane that forms a near 90-degree angle with the peritoneum. This makes the procedure difficult and complicated, and it is easy to penetrate the peritoneum, causing damage to the child. This leads to increased surgery time and a higher risk of complications.

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high ligation device for inguinal oblique hernia sac.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high ligation device for inguinal oblique hernia sac, comprising a puncture needle body, the puncture needle body being composed of a straight section and a spiral section, the spiral section being disposed at one end of the straight section, and the other end of the spiral section being connected to a joint, the end of the joint being provided with a joint end cap, the interior of the joint end cap being provided with a through hole, the interior of the puncture needle body being provided with a first thread and a second thread, the first thread and the second thread being sequentially passed through the straight section, the spiral section and the joint, and the first thread being connected to the end of the second thread after passing through the joint end cap, the interior of the straight section end cap being provided with a separator near the inner side of the handle.

[0006] As a further improvement to the technical solution of this utility model, the straight section and the spiral section are an integral structure, and the thickness of the straight section and the spiral section is the same.

[0007] As a further improvement to the technical solution of this utility model, the separator includes a connecting rod horizontally arranged inside the straight section, and both ends of the connecting rod are connected to the inner wall of the straight section with end pieces.

[0008] As a further improvement to the technical solution of this utility model, the connecting rod and the end plate are made of one piece of stainless steel, and the end plate is bonded and fixed to the inner wall of the straight section by hot melt adhesive.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-3The device shown is a high ligation device for inguinal oblique hernia sac, including a puncture needle body, which is composed of a straight section 1 and a spiral section 2. The spiral section 2 is located at one end of the straight section 1, and the other end of the spiral section 2 is connected to a joint 4. The end of the joint 4 is provided with a joint end 5, and the interior of the joint end 5 is provided with a through hole 8. A first thread 6 and a second thread 7 are passed through the interior of the puncture needle body. The first thread 6 and the second thread 7 pass through the straight section 1, the spiral section 2 and the joint 4 in sequence. The first thread 6 passes through the joint end 5 and is connected to the end of the second thread 7. A separator 9 is provided inside the end of the straight section 1 near the inner side of the handle 3.

[0020] As attached Figure 1 As shown, the straight section 1 and the spiral section 2 are an integral structure, and the thickness of the straight section 1 and the spiral section 2 is the same.

[0021] As attached Figure 1-2 As shown, the separator 9 includes a connecting rod 902 horizontally disposed inside the straight section 1. Both ends of the connecting rod 902 are connected to the inner wall of the straight section 1 with end pieces 901. The connecting rod 902 and the end pieces 901 are made of stainless steel as a single piece. The end pieces 901 are bonded and fixed to the inner wall of the straight section 1 with hot melt adhesive, which facilitates the separation of the first thread 6 and the second thread 7 during use, and avoids the problem of the first thread 6 and the second thread 7 getting tangled and knotted inside the puncture needle body, thus affecting the use.

[0022] As attached Figure 1 and attached Figure 3 As shown, the joint portion 4 is provided with a first through hole 10 and a second through hole 11 for the first thread 6 and the second thread 7 to pass through, so that the first thread 6 and the second thread 7 can pass through the joint portion 4 stably.

[0023] As attached Figure 1 and attached Figure 3 As shown, a limiting ball head 12 is fixedly installed on the outside of the second thread 7 inside the spiral segment 2. The diameter of the limiting ball head 12 is larger than the vertical cross-sectional diameter of the second perforation 11. The joint part 4 and the joint end 5 are both made of flexible and bendable medical plastic material. When the first thread 6 is pulled to drive the second thread 7 to move, the limiting ball head 12 limits the movement of the joint. When the first thread 6 is pulled further, the joint bends due to the limiting effect. After the tension on the first thread 6 is released, the joint returns to its original position.

[0024] Working principle: This utility model designs a high ligation device for inguinal hernia sac, the specific structure of which is shown in the attached instruction manual. Figure 1-3As shown, in this technical solution, the puncture needle body consists of two parts: a straight section 1 and a spiral section 2. The tip of the puncture needle body is equipped with a movable joint (joint part 4 and joint end 5) to avoid penetrating the peritoneum. Both the joint part 4 and the joint end 5 are made of flexible and bendable medical plastic material. When the first suture 6 is pulled to move the second suture 7, the limiting ball head 12 limits the movement of the joint. When the first suture 6 is pulled further, the joint bends due to the limiting effect. After the tension on the first suture 6 is released, the joint returns to its original position. The puncture needle body is designed with a spiral structure, which can complete the inner ring opening with a single needle. The separator 9 is provided to separate the first suture 6 and the second suture 7 during use, avoiding the problem of the first suture 6 and the second suture 7 getting tangled and knotted inside the puncture needle body, which affects the use. This can shorten the operation time, make the operation simple and easy to learn, reduce damage to children, and reduce the occurrence of complications.

Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0026] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
