Description

Technical Field

[0001] This utility model relates to sutures, and more particularly to a surgical suture with adjustable thickness. Background Technology

[0002] Surgical sutures play a vital role in modern surgery, closing various types of wounds. Currently, barbed sutures are widely used clinically to effectively reduce suture slippage. However, when suturing on capsules containing flowing fluid, small gaps inevitably form between the suture and the suture hole after closure. These gaps often lead to chronic fluid leakage, frequently resulting in cerebrospinal fluid leakage or blood loss. Summary of the Invention

[0003] The problem this invention aims to solve is to provide a surgical suture with adjustable thickness, reducing the gap between the suture and the suture hole, thereby reducing cerebrospinal fluid leakage or blood loss.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a surgical suture with adjustable thickness, including a needle and a suture body. The needle is located at one end of the suture body. The suture body includes an inner suture layer and an outer sheath wrapped around the inner suture layer. The outer sheath includes a first wrapping segment and a second wrapping segment from front to back. The front end of the first wrapping segment is provided with a closing layer, which is connected to the needle. The tail end of the first wrapping segment is connected to the second wrapping segment through an easy-tear thread. The working principle of this invention is as follows: Medical personnel pass the needle and suture through the suture area, at which point the second wrapping segment is located at the starting end and does not pass through the suture area. If interrupted suture is used, depending on the connection method between the needle and the closure layer, one hand pulls the needle or the closure layer, while the other hand holds the second wrapping layer, thereby separating the first and second wrapping layers. If continuous suture is used, the second wrapping segment is held down, and the other hand holds down the first wrapping segment adjacent to the second wrapping segment and located on the opposite side of the suture, separating the first and second wrapping segments. Then, the first wrapping segment is pulled out from the suture area in sequence. The inner suture expands to a certain extent, thereby reducing the gap between the suture and the suture hole, and thus reducing cerebrospinal fluid leakage or blood loss.

[0005] As an improvement, the needle is connected to the first package segment via an easy-tear line.

[0006] As an improvement, the needle is fixedly connected to the first wrapping segment.

[0007] As an improvement, the inner wall of the outer sleeve is smooth.

[0008] As an improvement, the outer sleeve is made of polyethylene plastic.

[0009] As an improvement, the stitching thread is made of silk or cotton.

[0010] The beneficial effects of this utility model are: the first wrapping segment and the second wrapping segment are connected by easy-tear thread, which makes it convenient for medical staff to put the first wrapping segment and the second wrapping segment together. At the same time, the overall operation of this utility model is simple; after the outer layer is separated from the inner suture, the inner suture expands to a certain extent, thereby reducing the gap between the suture hole and the suture, and thus reducing cerebrospinal fluid leakage or blood loss.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] like Figure 1 , 2As shown in Figure 3, a surgical suture with adjustable thickness includes a needle 3 and a suture body 1. The needle 3 is connected to one end of the suture body 1. The suture body 1 includes an inner suture 2 and an outer sheath wrapped around the inner suture 2. The outer sheath is U-shaped, and its interior forms a cavity for accommodating the inner suture 2. When the inner suture 2 is inserted into the cavity, it will be firmly wrapped. The suture is made of cotton or silk and has a certain degree of expandability. The outer sheath includes a first wrapping section 11 and a second wrapping section 12 from front to back. The front end of the first wrapping section 11 has a closing layer 111, which is connected to the needle 3. The rear end of the first wrapping section 11 is connected to the second wrapping section 12. The wrapping segment 12 is connected by an easy-tear thread, facilitating its removal after suturing. The outer sheath and needle 3 can be connected in two ways: First, the first wrapping segment 11 can be loosely connected to the needle 3, for example, by connecting the needle 3 to the first wrapping segment 11 via an easy-tear thread. After suturing, medical personnel can separate the needle 3 and the first wrapping segment 11 by pulling them apart with both hands, then press down on the closure layer 111 and the second wrapping segment 12 to remove the first wrapping segment 11. Second, the needle 3 and the first wrapping segment 11 are fixedly connected, and the closure layer 111 is also fixedly connected to the needle 3. After suturing, the needle 3 can be pulled directly to remove the first wrapping segment 11. The inner wall of the outer sheath is smooth, and the outer sheath is made of polyethylene plastic to ensure that the friction between the inner suture 2 and the outer sheath is not excessive, avoiding difficulty in removal.

[0017] The working principle of this utility model is as follows: Medical staff pass the needle 3 and the suture end through the suture area 4. At this time, the second wrapping segment 12 is located at the starting end and does not pass through the suture area 4. If the interrupted suture method is used, depending on the connection method between the needle 3 and the closing layer 111, one hand pulls the needle 3 or the closing layer 111, while the other hand holds the second wrapping layer, thereby separating the first wrapping layer and the second wrapping layer. If the continuous suture method is used, the second wrapping segment 12 is held down, and the other hand holds the first wrapping segment 11, which is adjacent to the second wrapping segment 12 and located on the opposite side of the suture, to separate the first wrapping segment 11 and the second wrapping segment 12. Then, the first wrapping segment 11 is pulled out from the suture area 4 in sequence. Since the inner suture 2 is made of cotton thread or silk, it has a certain degree of expansion, and the outer sheath has a small wall thickness. After the first wrapping segment 11 is separated from the inner suture 2, the inner suture 2 will expand and hold the suture hole, thereby reducing the gap between the suture and the suture hole, and thus reducing cerebrospinal fluid leakage or blood loss.
