Double-needle bidirectional barb surgical suture with buckle ring in middle

Abstract

A double-needle bidirectional barb surgical suture with a buckle ring in the middle comprises a single suture, suture needles are arranged at two ends of the suture, barb suture bodies on two sides of the suture are respectively provided with barbs with barbs pointing to the middle, the buckle ring is arranged in the middle of the barb suture bodies, and the barb suture bodies are made of absorbable materials. After the sutured first needle is used for suturing the tissue, the suture needle on one side penetrates into the buckling ring and then is tensioned, so that the first needle is used for suturing the tissue and is locked, and tissue damage caused by excessive traction of the barb line on the other side of the buckling ring towards the barb opening direction in the traction process when the suture needles on the two sides are continuously used for suturing the tissue subsequently can be avoided; by means of the device, the suture line can be conveniently pulled to twist the intestinal canal in the surgical anastomosis operation process of the gastrointestinal tract, so that an operation operator can conveniently suture the lateral and dorsal intestinal walls, and the gastrointestinal tract operation, especially the gastrointestinal tract anastomosis under a laparoscope, can be facilitated.

Description

Technical Field

[0001] The invention relates to medical surgical supplies, in particular to a double-needle bidirectional barbed surgical suture with a buckle and locking ring in the middle, which is mainly but not limited to being used for gastrointestinal anastomosis in minimally invasive surgery. Background Art

[0002] Gastrointestinal anastomosis is a highly difficult technique in gastrointestinal surgery, especially laparoscopic operation has higher requirements. Barbed sutures eliminate the knotting operation at each suture segment or at the end of suture in traditional continuous sutures. At the same time, the barbs are anchored to prevent tissue from retracting, which significantly shortens the anastomosis time. However, during surgical operation, especially laparoscopic operation, the surgeon still has difficulty suturing the contralateral and dorsal intestinal walls. The sutures need to be pulled to twist the intestinal tube to complete the operation. Unidirectional barbs are not convenient for traction operation. At the same time, due to the fragility of gastrointestinal tissue, the barbs can only serve as anchors to prevent tissue from retracting after the barbed suture is sutured to the gastrointestinal tissue. Once the bidirectional barbs are pulled, the barbs in the reverse direction will damage the gastrointestinal tissue during the traction process, resulting in anastomosis failure, and thus cannot be used in gastrointestinal anastomosis. Therefore, developing a barbed suture that is convenient for gastrointestinal anastomosis surgery and avoids tissue damage caused by pulling the suture during the surgical operation is a technical problem that needs to be seriously addressed. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a double-needle, bidirectional, barbed surgical suture with a buckle and locking ring in the middle. The surgical suture includes a single suture needle with two ends, and the barbed wire bodies on both sides have barbed openings pointing to the barbs in the middle. There is a buckle and locking ring in the middle of the barbed wire body. The barbed wire body is made of absorbable material. In this way, during the gastrointestinal tract suture operation, after the first stitch is sutured to the tissue, one side of the suture needle is inserted into the buckle and locked, so that the first stitch sutured tissue is locked. This can avoid the subsequent continuous suture of the tissue with needles on both sides during the pulling process, which causes tissue damage due to the excessive pulling of the barb wire on the other side of the buckle and locking ring toward the barb opening. It is convenient for the surgical anastomosis of the gastrointestinal tract to pull the suture to twist the intestinal tube, so as to facilitate the suturing of the contralateral and dorsal intestinal walls by the operator.

[0004] The present invention has a simple structure, is novel and unique, and has good use effect. It can facilitate gastrointestinal surgery, especially laparoscopic gastrointestinal anastomosis, ensure the success of the operation, and improve the surgical treatment effect. It is an innovation in sutures and has huge economic and social benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The specific embodiments of the present invention will be described in detail below with reference to Figures 1, 2, 3 and 4.

[0010] Depend on Figure 1 As shown, the present invention is a double-needle bidirectional barbed surgical suture with a buckle locking ring in the middle. The surgical suture includes a single suture needle with two ends, and the barbed wire bodies on both sides have barbed openings pointing to the barb in the middle. There is a buckle locking ring in the middle of the barbed wire body, and the barbed wire body is made of absorbable material.

[0011] When the present invention is used, Figure 2 As shown, in the gastrointestinal tract suturing operation, after the first stitch is sutured, one side of the suture needle is inserted into the buckle locking ring and then tightened to lock the first stitch sutured tissue. This can prevent the barbed line on the other side of the buckle locking ring from being pulled toward the barb opening during the subsequent pulling process when the tissue is continuously sutured with the suture needles on both sides, causing tissue damage; Figure 3 As shown, after suturing and fixing the first needle with the buckle ring, the gastrointestinal tissue that needs to be anastomosed can be continuously sutured with the needles at both ends of the suture body according to the suturing needs; Figure 4 As shown, during the suturing process, when it is necessary to twist the sutured intestinal tube and suture the posterior wall, the two ends of the suture body can be pulled. Since the first stitch fixes the intestinal tissue through the buckle ring suture, it is convenient to pull the sutures on both sides to twist the intestinal tube, which facilitates the surgical anastomosis operation of the gastrointestinal tract.

[0012] The present invention has a simple structure, is novel and unique, is easy to use, and has good effects. It can effectively facilitate the gastrointestinal suturing operation during surgery, effectively ensure the success of the operation, and is very beneficial for the gastrointestinal suturing operation under laparoscopic surgery. It is a major innovation in barbed wires and has huge economic and social benefits.
