Description

Technical Field

[0001] The present invention relates to the technical field of absorbable surgical sutures, and particularly to an absorbable surgical suture. Background Art

[0002] The absorbable surgical suture is made of glycolide, lactide, cyclopropane carbonate and lactide, and is suitable for the suture and ligation of general soft tissues, but cannot be used in nerve surgery, cardiovascular surgery, etc. It can be completely degraded or absorbed by tissues in the body, has a small reaction with body tissues, and does not require suture removal after suture, solving the problem of the pain brought to patients by secondary surgery after using non-absorbable surgical sutures.

[0003] Currently, when surgical operators use absorbable surgical sutures to suture tissues, when they apply too much force, it is easy to cause the absorbable surgical suture to break, prolonging the suture time of surgical operations, reducing the efficiency of surgical operations, and even affecting the surgical treatment effect of patients.

[0032] Embodiment 1

[0033] Referring to Figures 1-8 , the present invention discloses an absorbable surgical suture, including a suture body 100. In this embodiment, the suture body 100 includes an outer layer 101, an inner layer 102 disposed within the outer layer 101, and a support member 103 disposed between the inner layer 102 and the outer layer 101. The designs of the outer layer 101, the inner layer 102, and the support member 103 enable the entire suture to have a certain strength, and also have a certain tensile property as a whole. Moreover, during subsequent melting and absorption, it also ensures that the melting speed is not very fast.

[0034] Furthermore, the present invention further includes a reinforcement assembly 200. The reinforcement assembly 200 is mainly used for support and can increase the main strength of the entire suture. In this embodiment, the reinforcement assembly 200 includes a bone chain 201 disposed within the inner layer 102, a melting plate 202 disposed on the bone chain 201, and a dissolving member 203 disposed on the melting plate 202. A plurality of melting plates 202 are connected together by the bone chain 201 and form a line along the length of the suture. A number of such lines are provided and are evenly laid on the outer side of the inner layer 102.

[0035] In this embodiment, when the dissolving member 203 is dissolving, it can pour more blood into the suture, thereby playing a certain role in accelerating the dissolution of the inner layer 102 of the suture. The dissolving member 203 includes a melting groove 203a formed in the melting plate 202, a decomposition plate 203b disposed in the melting groove 203a, and a plurality of through holes 203c disposed on the decomposition plate 203b. The melting plate 202 is hinged to the melting plate 202. There are a plurality of through holes 203c. Five large-sized through holes 203c are provided on each decomposition plate 203b, and four small-sized through holes 203c are provided near each large through hole 203c. The through holes 203c can better penetrate the blood downward.

[0036] In this embodiment, the support member 103 includes a pillar layer 103a disposed between the inner layer 102 and the outer layer 101, and a plurality of retention grooves 103b formed in the pillar layer 103a.

[0037] In this embodiment, the supporting member 300 includes a bracket 301 disposed in the outer layer 101 and a protection member 302 disposed in the bracket 301. The bracket 301 includes a plurality of connecting bar frames 303 connected to the connecting cylinder. In this embodiment, there are 8 connecting bar frames 303, which are arranged in a ring shape, and the connecting bar frames 303 are disposed in the retention grooves 103b.

[0038] A gasket 304 is fixedly connected to the lower ends of the plurality of connecting bar frames 303. The gasket 304 is circular in shape, with the inner edge retracting inward and the outer edge extending outward. The gasket 304 and the connecting bar frame 303 form a cylindrical-like bearing space, and a protection member 302 is disposed in the formed bearing space.

[0039] In this embodiment, the protection member 302 has openings at both ends and is in the shape of a hollow long cylindrical. The outer diameter of the blood is smaller than the inner diameter of the connecting cylinder, the outer diameter of the blood is smaller than the outer diameter of the gasket 304, and larger than the inner diameter of the gasket 304, ensuring that the bottom of the blood is supported by the gasket 304.

[0040] Further, a protective layer 400 is provided between the inner layer 102 and the outer layer 101. The protective layer 400 includes a plurality of connected connecting ring bodies 401 and flexible bands 402 disposed between the connecting ring bodies 401.

[0041] In this embodiment, the connecting ring body 401 includes a first bent edge 401a, a second bent edge 401b connected to the first bent edge 401a, and an arc end connecting the first bent edge 401a and the second bent edge 401b. The arc end includes a first arc edge 401c and a second arc edge 401d. The connection point of the first arc edge 401c and the second arc edge 401d bends towards the directions of the first bent edge 401a and the second bent edge 401b. Thus, the connecting ring body 401 forms a shape similar to a heart. And the connection point of the first bent edge 401a and the second bent edge 401b is the thinnest part of the entire connecting ring body 401. When the blood dissolves, it will dissolve this part first and then enter the interior of the connecting ring body 401 from here, thereby expanding the entire connecting ring body 401 outwards.

[0042] A recessed groove 403 is provided on the inner wall of the connecting cylinder. The recessed groove 403 is circumferentially provided inside the connecting cylinder and recesses towards the inside of the connecting cylinder wall. And a first flanging 404 and a second flanging 405 are provided on the recessed groove 403, and the first flanging 404 and the second flanging 405 are arranged in a ring shape.

[0043] Furthermore, there is a certain height difference between the first flanging 404 and the second flanging 405. The shapes of the first flanging 404 and the second flanging 405 are both annular without external force. When blood enters the connecting cylinder, the blood will stir the first flanging 404 and the second flanging 405.

[0044] Preferably, the width ratio of the second flanging 405 to the width of the first flanging 404 is 1:1.8 - 1:2. Thus, when the blood is inserted, the flipping area of the first flanging 404 is larger than that of the second flanging 405, so that the first flanging 404 has a larger relative area in contact with the blood.

[0045] Furthermore, a bent flanging 406 is provided on the upper surface of the first flanging 404. The bent flanging 406 faces upwards. When the second flanging 405 is bent by the inserted blood, it will be blocked by the bent flanging 406 and guided by the bent flanging 406 to bend further, thus forming a bent space, so that the blood accumulates here. And this place exactly corresponds to the connection point of the first bent edge 401a and the second bent edge 401b. Thus, the blood pressure here increases, further enhancing the dissolution effect.

[0046] Preferably, a number of water-permeable holes are provided on the bent flanging 406. In this embodiment, the outer layer 101 includes a thick skin and a number of bending points provided on the thick skin.

[0047] Operation process: In the initial state, the first flanging 404 and the second flanging 405 are in a bent state. When the second flanging 405 is bent, the second flanging 405 cooperates with the bent flanging 406, and after being guided by the bent flanging 406, it bends back to form a blood storage space. At this time, the blood will be blocked by the first flanging 404 first. After the first flanging 404 fails to block, the water flow breaks through the first flanging 404, and the water flow enters the blood storage space through the water permeable holes. Due to the structural design of the water permeable holes, the amount of water flowing out of the water storage space is less than the amount of water entering the water storage space, so that the water flow accumulates in the water storage space, and this place exactly corresponds to the connection between the first bent edge 401a and the second bent edge 401b, thereby increasing the pressure of the blood here and further enhancing the dissolution effect.
