Detailed Implementation

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Example 1:

[0023] like Figure 1 As shown, a stitch fastening buckle includes an upper pressing part 200 and a lower closing part 100. Both the upper pressing part 200 and the lower closing part 100 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 by a connecting part 300 with an arc-shaped structure to form an integral structure. The upper pressing part 200, the lower closing part 100 and the connecting part 300 are made of an elastic deformable material, which 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 fastened together.

[0024] like Figure 1 As shown, the upper pressing part 200 and the lower closing part 100 are in the open state. Figure 2 As shown, the upper pressing part 200 and the lower closing part 100 are in a snap-fit ​​connection state.

[0025] like Figure 1 As shown, the lower closing part 100 has horizontally arranged lower closing end faces on its left and right sides, and a protruding lower closing structure is provided on the lower closing end face along the length direction. The upper pressing part 200 has horizontally arranged upper pressing end faces on its left and right sides, and the two upper pressing end faces and the two lower closing end faces are arranged face to face. A protruding upper pressing structure is provided on the upper pressing end face along the length direction. The lower closing structure and the upper pressing structure are staggered in the width direction to form an interlocking effect. When the closed end of the upper pressing part 200 and the closed end of the lower closing part 100 are fastened together, the lower closing structure and the upper pressing structure cooperate to fix the suture 400.

[0026] like Figure 1 As shown, the lower joint structure includes two lower protrusions arranged side by side. Each lower protrusion is composed of multiple lower protrusions 110 of equal size. The multiple lower protrusions 110 are distributed in a straight line along the length direction of the lower joint end face, and a gap is provided between two adjacent lower protrusions 110.

[0027] like Figure 1As shown, the upper pressing structure includes two upper protrusions arranged side by side. Each upper protrusion is composed of multiple upper protrusions of equal size. The multiple upper protrusions 210 are distributed in a straight line along the length direction of the upper pressing end face, and a gap is provided between two adjacent upper protrusions 210.

[0028] The upper protrusion 210 and the lower protrusion 110 are staggered along the length direction. The gap between adjacent upper protrusions 210 is filled by the lower protrusion 110, and the gap between adjacent lower protrusions 110 is filled by the upper protrusion 210, thereby reliably fixing the suture.

[0029] like Figure 1 As shown, a protruding fastening plate 220 is provided in the middle of the upper pressing part 200, located between the two upper pressing end faces. A through-groove groove 130 is provided in the middle of the lower closing part 100, located between the two lower closing end faces, allowing the fastening plate 220 to enter and achieve the fastening action. A fastening baffle 120 is provided in the middle of the closed end of the lower closing part 100, located at one end of the through-groove 130. A recessed slot 221 is provided at one end of the fastening plate 220, allowing the fastening baffle 120 to engage, thus achieving a fastening connection between the closed ends of the upper pressing part 200 and the lower closing part 100. In use, the fastening plate 220 can tension and fix the suture 400, further improving the fixation effect of the suture 400.

[0030] 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 fastening baffle 120 is an inclined first sliding slope 121. During the fastening 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 allows the fastening baffle 120 to gradually slide into the slot 221.

[0031] like Figure 1 As shown, the closed end of the upper pressing part 200 is provided with an upper limit post 230 laterally, and the closed end of the lower closing part 100 is provided with two protruding blocks, which are located on the left and right sides of the fastening baffle 120, respectively. The upper end surface of the blocks is provided with an arc-shaped limiting end face 140. When the closed ends of the upper pressing part 200 and the lower closing part 100 are fastened together, the two ends of the upper limit post 230 can respectively engage with the two limiting end faces 140, and the upper limit post 230 and the two limiting end faces 140 cooperate to achieve a limiting effect. The closed end of the lower closing part 100 is provided with a lower limit post 150 laterally.

[0032] This utility model is operated by clamping with a clamping pliers, with the upper and lower jaws of the clamping pliers respectively clamping the upper limit post 230 and the lower limit post 150.

[0033] like Figure 1 As shown, a recessed deformation groove 310 is provided on the inner end of the connecting part 300 along the width direction. When the upper pressing part 200 and the lower closing part 100 are fastened together, the deformation groove 310 can accommodate the deformation formed by the connecting part 300 being squeezed inward.

[0034] like Figure 1 As shown, the other end of the fastening plate 220 extends downward into the relief groove 130, so that the other end of the fastening plate 220 can prevent the suture line from sliding laterally into the deformation groove 310. Example 2:

[0035] like Figure 3 and Figure 4 As shown, unlike Embodiment 1, a dividing groove 240 is provided along the length of the middle portion of the fastening plate 220, dividing the fastening plate 220 into two parts. A dividing plate 160 is provided along the length of the middle portion of the clearance groove 130, dividing the clearance groove 130 into two parts. When the closed end of the upper pressing part 200 and the closed end of the lower closing part 100 are fastened together, the bottom end surface of the dividing groove 240 can contact the dividing plate 160. The cooperative arrangement of the dividing groove 240 and the dividing plate 160 causes the suture 400 at this position to be stretched and tightened repeatedly from top to bottom, further improving the fixation effect of the suture 400.

[0036] like Figure 3 As shown, multiple protruding limiting teeth 250 are provided on the surface of the fastening plate 220 along the length direction. The suture 400 can be locked in a certain limiting tooth 250, and the limiting tooth 250 fixes the lateral position of the suture 400.

[0037] This invention can be made of absorbable or non-absorbable polymeric biomaterials to complement the use of absorbable or non-absorbable sutures.

[0038] The working principle of this utility model is as follows: When fixing the suture 400, the suture is first passed laterally between the upper pressing part 200 and the lower closing part 100, and then the upper pressing part 200 and the lower closing part 100 are closed. During the closing process, the fastening plate 220 presses the suture 400 into the relief groove 130, so that the suture 400 is fully tensioned. The lower end of the fastening plate 220 extends into the relief groove 130 to prevent the suture 400 from sliding laterally into the deformation groove 310, and the position of the suture 400 is limited to one side of the fastening plate 220. The second sliding inclined surface 222 of the fastening plate 220 and the first sliding inclined surface 121 of the fastening baffle 120 contact each other and slide relative to each other, so that the fastening baffle 120 gradually slides into the slot 221, realizing the fastening connection between the upper pressing part 200 and the lower closing part 100. When the upper pressing part 200 and the lower closing part 100 are fastened together, a portion of the suture 400 is pressed into the relief groove 130 by the fastening plate 220, and the other part of the suture 400 is pressed and fixed by the cooperation of the lower closing structure and the upper pressing structure, thus achieving stable fixation of the suture 400.
