DETAILED DESCRIPTION

[0020] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:

[0021] like Figure 1 As shown, a suture fixing buckle includes an upper pressing part 200 and a lower closing part 100. The upper pressing part 200 and the lower closing part 100 both have a closed end and a connecting end. The connecting end of the upper pressing part 200 and the connecting end of the lower closing part 100 are connected to form an integral structure through a connecting part 300 with an arc structure. The upper pressing part 200, the lower closing part 100 and the connecting part 300 are made of elastic deformable material and can produce a certain deformation. The closed end of the upper pressing part 200 and the closed end of the lower closing part 100 can be buckled and connected.

[0022] like Figure 1 As shown, the upper pressing portion 200 and the lower closing portion 100 are in an open state. Figure 2 As shown, the upper pressing portion 200 and the lower closing portion 100 are in a buckled connection state.

[0023] like Figure 1 As shown, the left and right sides of the lower closing part 100 are respectively horizontally arranged lower closing end faces, and a protruding lower closing structure is arranged on the upper length direction of the lower closing end faces, and the left and right sides of the upper pressing part 200 are respectively horizontally arranged upper pressing end faces, the two upper pressing end faces and the two lower closing end faces are arranged face to face with each other, and a protruding upper pressing structure is arranged on the upper length direction of the upper pressing end faces, and the lower closing structure and the upper pressing structure are staggered with each other in the width direction to form a jagged effect. When the closed end of the upper pressing part 200 and the closed end of the lower closing part 100 are buckled together, the lower closing structure and the upper pressing structure cooperate to fix the suture line 400.

[0024] like Figure 1 As shown, the lower closure structure includes two lower convex strips arranged side by side, each lower convex strip is composed of multiple lower convex blocks 110 of equal size, and multiple lower convex blocks 110 are distributed in a straight line along the length direction of the lower closure end surface, and a gap is set between two adjacent lower convex blocks 110.

[0025] like Figure 1As shown, the upper pressing structure includes two upper convex strips arranged side by side, each upper convex strip is composed of multiple upper convex blocks of equal size, and multiple upper convex blocks 210 are distributed in a straight line along the length direction of the upper pressing end surface, and a gap is set between two adjacent upper convex blocks 210.

[0026] The upper protrusions 210 and the lower protrusions 110 are staggered in the length direction. The gaps between adjacent upper protrusions 210 are filled by the lower protrusions 110, and the gaps between adjacent lower protrusions 110 are filled by the upper protrusions 210, thereby reliably fixing the suture thread.

[0027] like Figure 1 As shown, a protruding snap-fit plate 220 is provided in the middle of the upper pressing portion 200, and the snap-fit plate 220 is located between the two upper pressing end surfaces. A vertically extending escape groove 130 is provided in the middle of the lower closing portion 100, and the escape groove 130 is located between the two lower closing end surfaces. The escape groove 130 can accommodate the snap-fit plate 220, thereby achieving a snap-fitting action. A snap-fitting baffle 120 is provided in the middle of the closed end of the lower closing portion 100, and the snap-fitting baffle 120 is located at one end of the escape groove 130. A recessed latching slot 221 is provided at one end of the snap-fitting plate 220, and the latching slot 221 can latch the snap-fitting baffle 120, thereby achieving a snap-fitting connection between the closed end of the upper pressing portion 200 and the closed end of the lower closing portion 100. During use, the snap-fitting plate 220 can tension and secure the suture 400, further improving the securing effect of the suture 400.

[0028] like Figure 1 As shown, one end wall of the slot 221 is an inclined second sliding slope 222, and the upper end surface of the snap-fit baffle 120 is an inclined first sliding slope 121. During the snap-fit process, the second sliding slope 222 and the first sliding slope 121 can contact each other and slide relative to each other. The cooperation between the second sliding slope 222 and the first sliding slope 121 can allow the snap-fit baffle 120 to gradually slide into the slot 221.

[0029] like Figure 1 As shown, an upper limit post 230 is disposed transversely at the closed end of the upper pressing portion 200, and two raised support blocks are disposed at the closed end of the lower closing portion 100. The two support blocks are located on the left and right sides of the buckling baffle 120, respectively. The upper end surfaces of the support blocks are provided with arc-shaped limit end surfaces 140. When the closed end of the upper pressing portion 200 and the closed end of the lower closing portion 100 are buckled and connected, the two ends of the upper limit post 230 can respectively align with and contact the two limit end surfaces 140. The upper limit post 230 and the two limit end surfaces 140 cooperate to achieve a limiting effect. A lower limit post 150 is disposed transversely at the closed end of the lower closing portion 100.

[0030] The present invention is operated by clamping with a clip applier when in use, and the upper and lower jaws of the clip applier clamp the upper limit post 230 and the lower limit post 150 respectively.

[0031] like Figure 1 As shown, a concave deformation groove 310 is provided at the inner end of the connecting portion 300 along the width direction. When the upper pressing portion 200 and the lower closing portion 100 are buckled together, the deformation groove 310 can accommodate the deformation of the connecting portion 300 caused by being squeezed inward.

[0032] like Figure 1 As shown, the other end of the fastening plate 220 extends downward into the avoidance groove 130 , so that the other end of the fastening plate 220 can prevent the suture thread from sliding laterally into the deformation groove 310 . Example 2:

[0033] like Figure 3 and Figure 4 As shown, the difference from the first embodiment is that a dividing groove 240 is provided in the middle of the snap plate 220 along the length direction, dividing the snap plate 220 into two. A dividing plate 160 is provided in the middle of the avoidance groove 130 along the length direction, dividing the avoidance groove 130 into two. When the closed end of the upper pressing portion 200 and the closed end of the lower closing portion 100 are snapped together, the bottom end surface of the dividing groove 240 can contact the dividing plate 160. The coordinated arrangement of the dividing groove 240 and the dividing plate 160 allows the suture thread 400 at this position to be stretched and tensioned multiple times, further improving the fixing effect of the suture thread 400.

[0034] like Figure 3 As shown, a plurality of protruding limiting teeth 250 are provided on the surface of the fastening plate 220 along the length direction. The suture thread 400 can be stuck in a certain limiting tooth 250, and the limiting teeth 250 fix the lateral position of the suture thread 400.

[0035] The present invention can be made of absorbable or non-absorbable polymer biomaterials to match the use of absorbable or non-absorbable sutures.

[0036] The working principle of the present invention is as follows: when securing the suture 400, the suture is first passed transversely between the upper pressing portion 200 and the lower closing portion 100, and then the upper pressing portion 200 and the lower closing portion 100 are closed. During the closing process, the snap plate 220 presses the suture 400 into the avoidance groove 130, fully tensioning the suture 400. The lower end of the snap plate 220 extends into the avoidance groove 130, preventing the suture 400 from sliding transversely into the deformation groove 310. The position of the suture 400 is confined to one side of the snap plate 220. The second sliding inclined surface 222 of the snap plate 220 and the first sliding inclined surface 121 of the snap stop plate 120 contact each other and slide relative to each other, causing the snap stop plate 120 to gradually slide into the retaining groove 221, thereby achieving a snap connection between the upper pressing portion 200 and the lower closing portion 100. When the upper pressing portion 200 and the lower closing portion 100 are buckled together, a portion of the suture thread 400 is pressed into the avoidance groove 130 by the buckling plate 220, and the other portion of the suture thread 400 is pressed and fixed by the lower closing structure and the upper pressing structure, ultimately achieving stable fixation of the suture thread 400.
