The structure is similar to that of staplers, and the legs can penetrate into the tissue. After the stapler controls the deformation of the staple, the two legs can be fixed on the tissues on both sides of the wound respectively, thereby achieving the effect of tissue anastomosis. However, this type of stapler cannot effectively compress the tissue and has a poor hemostatic effect. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention aims to provide a suture clip to solve the technical problems that the prior suture clips cannot effectively compress tissues and have poor hemostatic effects.

[0008] Furthermore, the deformable arm includes a first state and a second state. In response to applying force to the deformable arm, the deformable arm switches from the first state to the second state. In the first state, the deformable arm has a first curvature, and in the second state, the deformable arm has a second curvature, wherein the second curvature is greater than the first curvature.

[0009] Furthermore, the free end of the deformable arm has an arc-shaped rounded corner.

[0010] Furthermore, each of the nail arms is connected to at least one of the extrusion pieces, and the extrusion pieces on the two nail arms are arranged opposite to each other.

[0018] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] It should be understood that the terms "proximal" and "distal" used herein are relative to the clinician manipulating the surgical instrument. The term "proximal" refers to the part close to the clinician, and the term "distal" refers to the part away from the clinician.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms such as "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movably connection, or an integral body; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements such as abutment. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. It should be noted that when there are qualifiers before "connected" and "connection", they have the meaning defined by the corresponding qualifiers, and only exclude situations that obviously need to be excluded, and do not exclude other possible situations. For example, "detachably connected" refers to a detachable connection, and does not include integration, but movable connection, etc. are not excluded.

[0021] In order to solve the problem that the suture clips in the prior art cannot compress tissues and have poor hemostatic effects, the present application provides a suture clip that can effectively compress tissues, improve hemostatic effects, and improve anastomosis effects.

[0022] See also Figure 1-Figure 4As shown, this embodiment provides a suture clip, including two nail arms, nail legs, a bending portion 30 and an extrusion member 40, the nail legs are arranged on the nail arms, the nail legs have sharp ends, and the sharp ends (tip) can penetrate into the tissue 100, the two nail arms are rigidly connected to the bending portions 30 respectively, in response to the force applied to the nail arms, the bending portions 30 are deformed, the nail legs on the two nail arms are relatively close, and the bending portions 30 can maintain the deformed shape unchanged, so as to maintain the relative position between the two nail arms unchanged, and further maintain the relative position between the nail legs and the tissue 100 unchanged. In the present invention, the meaning of "arrangement" is equivalent to "connection".

[0023] In this embodiment, the purpose of fixing, preliminarily compressing and anastomosing the tissue 100 is achieved through two nail arms and nail legs. The extrusion piece 40 further concentrates the tissue 100 on one side of the nail leg, thereby improving the compression effect on the tissue 100, avoiding bleeding from the wound, and improving the overall anastomosis effect of the suture clip.

[0024] For the convenience of explanation, the sharp end is referred to as a “tip” below, and the suture clip can penetrate into the tissue 100 through the tip.

[0025] In one example, reference Figure 1 and Figure 5 As shown, the extension direction of the nail leg is roughly perpendicular to the plane where the nail arm is located, the nail leg is arranged at the end of the nail arm, and the squeezing member 40 compresses the tissue toward one side of the nail leg.

[0026] Among them, the two nail arms are rigidly connected to the two ends of the bending part 30 respectively. Here, "rigid connection" includes a fixed connection or an integrally formed connection between the nail arm and the bending part 30. After deformation, the bending part 30 can keep the spacing distance between the two nail arms after closing unchanged, effectively preventing the suture clip from falling off the tissue 100.

[0027] For further reference, Figure 1 , Figure 3 , Figure 5 , Fig. 9 As shown, the nail arm has a certain width, and the width of the nail arm is greater than the width of the nail leg. After the nail leg penetrates the tissue, the contact area between the nail arm and the tissue is larger, which can effectively avoid the rotation of the nail arm relative to the tissue, so as to further improve the reliability of the suture clip anastomosis.

[0028] Further, refer to Figure 3 , Figure 5 as well as Figure 7 As shown, the relative rotation between the nail arm and the tissue 100 can also be avoided by increasing the number or arrangement of the nail legs on the nail arm. As an example, at least two nail legs are arranged on one of the nail arms, and the nail arm has a certain width and length. The at least two nail legs are spaced apart along a first direction, wherein the first direction is the width direction of the nail arm, and the length direction of the nail arm is the second direction 300.

[0029] In another example, one of the nail arms is provided with at least two nail legs, at least two first nail legs 11 are provided on the first nail arm 10, and a cavity 102 is provided between adjacent first nail legs 11; the other nail arm is provided with at least one nail leg, and at least one second nail leg 21 is provided on the second nail arm 20, and the second nail leg 21 faces the cavity 102. In response to the closing of the two nail arms, the second nail leg 21 penetrates into the tissue 100 in the cavity 102. The number of the second nail legs 21 is the same as the number of the cavity 102, which can further prevent the suture clip from rotating relative to the tissue 100 and improve the stability of the suture clip anastomosis.

[0030] The extrusion member 40 includes a deformable arm 41. In response to the force applied to the deformable arm 41, the deformable arm 41 deforms and approaches the nail leg, and the deformable arm 41 pushes the tissue 100 to concentrate on the nail leg. After the deformation, the deformable arm 41 can maintain the deformed shape unchanged, keep the relative position between the deformable arm 41 and the nail leg unchanged, and then continue to compress the tissue 100 on the nail leg side to improve the hemostasis effect.

[0031] Furthermore, the free end 413 of the deformable arm 41 has an arc-shaped fillet. When the deformable arm 41 is deformed and pushes against the tissue 100 , the contact portion between the free end 413 and the tissue 100 is an arc-shaped fillet, thereby preventing the deformable arm 41 from causing new damage to the tissue 100 .

[0032] For further reference, Figure 4 as well as Fig.10 As shown, in response to the force applied to the deformable arm 41, the deformable arm 41 will deform, push and wrap the tissue 100 toward one side of the nail leg to further increase the degree of compression on the tissue 100 and improve the hemostatic effect.

[0033] In one embodiment, the deformable arm 41 is disposed on the nail arm, and the fixed end of the deformable arm 41 is rigidly connected to the nail arm, wherein the fixed end of the deformable arm 41 is disposed on the nail arm between the nail leg and the bending portion 30, and the free end 413 extends substantially in a direction toward the bending portion 30 (hereinafter referred to as extending toward the bending portion 30), referring to Figure 1 and Figure 5 As shown, the fixed end 414 of the deformable arm 41 is arranged between two opposite sides in the width direction of the nail arm, with a certain spacing distance between the two sides. In response to the closing of the two nail arms, the effect of the deformable arm 41 concentrating the tissue facing the nail leg is further improved, thereby improving the compression and hemostasis effect of the overall suture clamp on the tissue 100.

[0034] For further reference, Figure 1 and Figure 5As shown, the nail arm includes a groove 101 opened on the surface, the groove 101 is a through groove that penetrates the nail arm in the thickness direction of the nail arm, and the extrusion member 40 is disposed in the groove 101. Furthermore, the fixed end 414 of the deformable arm 41 is rigidly connected to the end of the groove 101, and the free end 413 of the deformable arm 41 extends toward the bending portion 30, and the groove 101 provides a deformation space for the deformable arm 41.

[0035] As an example, both nail arms have a groove 101. When it is necessary to control the deformation of the deformable arm 41, it is convenient for the instrument to pass through the groove 101 to apply force to the deformable arm 41. As an example, the instrument applies a deforming force toward the nail leg side to the deformable arm 41 through the groove 101 on the two nail arms. After the deformable arm 41 is deformed, the deformed shape is maintained unchanged, and the deformable arm 41 continues to compress the tissue toward the nail leg side.

[0036] For further reference, Figure 1-Figure 16 As shown, the bending portion 30, the nail arm and the extrusion piece 40 are integrally formed and connected, which reduces the difficulty of manufacturing process. The nail arm, the bending portion 30 and the extrusion piece 40 are made of metal materials.

[0037] Furthermore, the bending portion 30 is provided with an avoidance cavity 31, and the grooves 101 on the two nail arms are connected through the avoidance cavity 31, so as to provide a larger operating space for external instruments to apply force to the deformable arm 41. Figure 1-Figure 4 as well as Figure 11-Figure 16 As shown, the deformable arm 41 extends along the second direction 300, wherein the second direction 300 is the length direction of the nail arm. Further, the free end 413 of the deformable arm 41 on one nail arm extends toward the avoidance cavity 31, or as shown in FIG. Figure 5-Figure 10 As shown, the deformable arm 41 on one nail arm extends through the avoidance cavity 31 to the groove body 101 on the other nail arm. For example, one of the two nail arms is the first nail arm 10 and the other is the second nail arm 20. The first nail arm 10 includes a first arm body 12, on which a first nail leg 11 is provided, and the first arm body 12 is surrounded by a groove body 101. The second nail arm 20 includes a second arm body 22, on which a second nail leg 21 is provided, and the second arm body 22 is surrounded by a groove body 101. The deformable arm 41 provided on the first arm body 12 extends through the avoidance cavity 31 to the groove body 101 on the second arm body 22, thereby increasing the extension length of the deformable arm 41 and increasing the wrapping area of ​​the deformable arm 41 on the tissue 100.

[0038] refer to Figure 5 and Figure 6 In the state shown, the extrusion members 40 on the two nail arms are arranged in a staggered manner, and in response to the bending portion 30 bending, the reference Figure 7 and Figure 8As shown, the intersecting part of the deformable arm 41 on the first arm body 12 and the deformable arm 41 on the second arm body 22 is located in the avoidance cavity 31 of the bending portion 30 and in the groove 101 of the two nail arms. The extension length of the deformable arm 41 is relatively long. After the instrument applies force to the deformable arm 41 to deform, Fig. 9 and Fig.10 In the state shown, the deformable arm 41 wraps around the tissue and compresses the tissue toward the nail leg. The setting of the avoidance cavity 31 provides a larger operating space for the instrument 50, making it easier for the instrument 50 to apply force to the deformable arm 41. Figure 7 and Figure 8 As shown, the free end 413 of the deformable arm 41 is exposed to the outside. In response to the instrument 50 applying force to the free end 413 of the deformable arm 41, the deformable arm 41 is deformed. Figure 8 The status shown is switched to Fig. 9 and Fig.10 In the state shown, the deformation arm 41 is bent and deformed, and the deformation arm 41 maintains the deformed shape unchanged and wraps the tissue 100 to concentrate on one side of the nail leg.

[0039] The deformable arm 41 can push the tissue 100 toward the nail leg. Figure 1-Figure 4 As shown, the deformation arms 41 on the two nail arms are symmetrically arranged, and each deformation arm 41 bends toward the inner side of the two nail arms. In response to the deformation of the bending portion 30, the free end 413 of the deformation arm 41 faces the bending portion 30 between the two nail arms, and the part of the deformation arm 41 except the free end 413 squeezes the tissue 100 toward one side of the nail leg.

[0040] refer to Figure 8 and Fig.14 As shown, the deformable arm 41 has a curvature relative to the nail arm toward the nail leg, which can compress the tissue. Fig. 9 as well as Fig.16 As shown, in response to the instrument 50 applying force to the deformable arm 41 , the deformable arm 41 further bends toward the nail leg side and wraps the tissue 100 to concentrate toward the nail leg side, thereby increasing the squeezing force on the tissue 100 .

[0041] In one embodiment, Figure 3 As shown, the deformable arm 41 has a suturing surface 411 and a force-applying surface 412 that are arranged opposite to each other. The suturing surface 411 abuts against the tissue 100 to squeeze the tissue toward the side of the nail leg.

[0042] In another embodiment, in reference Figure 3 and Figure 4 Based on the state shown, the external instrument 50 continues to apply force to the force-applying surface 412, and the deformable arm 41 switches from the first state to the second state. In the first state, the deformable arm 41 has a first curvature, and in the second state, the deformable arm 41 has a second curvature, wherein the second curvature is greater than the first curvature.

[0043] Among them, after the deformable arm 41 is bent by force, the suture surface 411 extends along the curve. The curvature of the curve is the rotation rate of the tangent direction angle of a point on the curve to the arc length. It is defined by differentiation and indicates the degree to which the curve deviates from the straight line. Mathematically, it is a numerical value indicating the curvature of the curve at a certain point. The larger the curvature, the greater the curvature of the curve.

[0044] The first state is the initial state. The bending degree of the deformation arm 41 in the first state is smaller than that in the second state. Figure 8 , Figure 11-Figure 14 The deformable arm 41 is in the first state, referring to Fig. 9 , Fig.10 as well as Fig.15 Fig.16 The deformable arm 41 is shown in the second state. Fig.14 and Fig.16 It can be seen that in response to the force applied to the deformable arm 41, the deformable arm switches from the first state to the second state, the second curvature of the deformable arm 41 is greater than the first curvature, the free end 413 of the deformable arm 41 further moves toward the nail leg side, and the deformable arm 41 wraps the tissue 100 and concentrates it toward the nail leg side.

[0045] To further enhance the compression effect of the extrusion member 40 on the tissue 100, at least one extrusion member 40 is provided on each nail arm of the suture clip, and the extrusion members 40 on the two nail arms are arranged oppositely. As an example, the suture clip includes two extrusion members 40, which are respectively arranged on the two nail arms and are arranged oppositely.

[0046] Regarding the relative arrangement of the two extrusion members 40, in one embodiment, as Figure 1-Figure 4 The extrusion members 40 on the two nail arms are arranged at intervals, that is, the deformation arms 41 of the two nail arms are not staggered. After the deformation arms 41 are deformed, the free ends of the two deformation arms 41 are relatively concentratedly abutted against the tissue, and the tissue is compressed toward the nail leg. In another embodiment, the two extrusion members 40 are staggered, such as Figure 5-Figure 16 The two extrusion members 40 are staggered, and compared with the embodiment in which the extrusion members are symmetrically arranged, in this embodiment, by staggering the extrusion members 40, after the deformation arms 41 on the two extrusion members 40 are deformed, the contact area between the deformation arms 41 and the tissue along the first direction 200, that is, the width direction of the nail arm, is increased. The two extrusion members 40 can be selectively arranged symmetrically or staggered according to actual needs.

[0047] In order to further understand the various embodiments of the present application, each embodiment is described in detail below. Embodiment 1:

[0048] refer to Figure 1 , Figure 2 As shown, no force is applied to the two nail arms, the bending portion 30 is not deformed, and the two extrusion members 40 are symmetrically arranged on the two nail arms. On one nail arm, the fixed end 414 of the deformable arm 41 is connected to the nail arm near the nail leg in the groove 101, and the free end 413 of the deformable arm 41 extends toward the avoidance cavity 31 in the groove 101 and bends to the side of the nail leg. The deformable arm 41 is in the first state, and the suture surface has a first curvature. When force is applied to the two nail arms, the bending portion 30 bends, and the bending portion 30 maintains the shape after bending. Figure 3 as well as Figure 4 As shown, the deformable arm 41 is in the first state.

[0049] And in Figure 4 In the case shown, the deformable arm 41 has pushed the tissue to concentrate on the side of the nail leg. The deformable arm 41 is selectively applied with force, and the deformable arm 41 continues to bend and deform. The deformable arm 41 is in the second state, and the suture surface has a second curvature. Since the first curvature is smaller than the second curvature, the tissue will be further compressed, thereby improving the hemostatic effect on the wound. Embodiment 2:

[0050] refer to Figure 5-Figure 10 As shown, different from the first embodiment, in this embodiment, the free end 413 of the deformable arm 41 on one nail arm passes through the avoidance cavity 31 and extends toward the groove body 103 of the other nail arm. When the deformable arm 41 is in the first state, as shown in FIG. Figure 8 As shown, the deformation arm 41 and the nail arm have substantially the same squeezing effect on the tissue. The free end 413 of the deformation arm 41 is bent toward the nail leg at a position close to the avoidance cavity 31. The deformation arm 41 has sufficient deformation space to facilitate the instrument 50 to apply force to the force-applying surface 412 of the deformation arm 41. In response to the force applied to the deformation arm 41, the deformation arm 41 is deformed. Fig. 9 and Fig.10 As shown, the deformable arm 41 is in the second state. In the second state, the contact area between the deformable arm 41 and the tissue in the first direction 200 becomes larger, and because the deformable arm 41 is longer, relative to the first embodiment, the wrapping area of ​​the tissue is increased, and the area and range of the tissue being squeezed toward the other side of the nail leg are increased. Embodiment three:

[0051] refer to Figure 11-Figure 16 As shown, compared with the first embodiment, the two extrusion members 40 are staggered, and compared with the second embodiment, the free end 413 of the deformation arm 41 extends toward the side of the avoidance cavity 31, but does not pass through the avoidance cavity 31, and the extension length of the deformation arm 41 is shorter. In addition, in the first state of the deformation arm 41, refer to Figure 11-Figure 14 As shown, the deformable arm 41 has a first curvature and squeezes the tissue toward one side of the nail leg, referring to Fig.15 and Fig.16As shown, in response to the force applied to the deformable arm 41, the deformable arm 41 has a second curvature, and the deformable arm 41 wraps a portion of the tissue and concentrates it toward one side of the nail leg.

[0052] In summary, the two ends of the bending portion 30 are rigidly connected to the two nail arms respectively. In response to the force applied to the two nail arms, the two nail arms are closed, and the nail legs on the nail arms have sharp tips, which penetrate into the tissue 100 through the sharp tips. The bending portion 30 is deformed and maintains the deformed shape unchanged to maintain the relative position between the two nail arms unchanged. The extrusion piece 40 squeezes the tissue 100 toward the side of the nail legs, thereby increasing the compression effect on the tissue 100, thereby increasing the compression force of the suture clip on the tissue 100 as a whole, and increasing the hemostatic effect of the suture clip on the wound.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
