Description

Technical Field

[0001] The invention relates to the technical field of medical suturing, in particular to an antibacterial medical suture assembly. Background Art

[0002] During surgery, it is often necessary to knot and fix sutures. Traditional surgical operations are performed under direct vision, and the doctor usually ties the knots manually. However, with the advancement of technology, various minimally invasive and interventional surgeries are becoming increasingly common, such as laparoscopic surgery and transcatheter interventional surgery. These surgeries only require a small operating window to be cut in the patient's body, through which instruments such as endoscopes or interventional catheters are inserted into the patient's body to reach the predetermined site for treatment. In this type of surgery, if the sutures in the patient's body need to be knotted or fixed, the operator usually needs to perform remote operations outside the patient's body through a small operating window.

[0003] In minimally invasive surgery, due to the small surgical space, it is very inconvenient to tie knots. Further, a suture tail locking component has been developed to replace the knotting and fixing of the suture tail. The tail of the suture is clamped by a block to prevent the suture from moving forward during the suturing process. The existing locking component cannot lock the suture tail well during use. If used for a long time, the locking component may fall off, which may cause the suture to fall off, causing the patient's wound to rupture, thereby affecting the patient's recovery process.

When the nut is rotated counterclockwise, the threads on the externally threaded barrel 1 and the externally threaded barrel 2 stagger with each other, preventing the nut from rotating, thereby preventing the nut from moving inward, thereby making the assembly have a self-locking function. The self-locking method is novel and does not require the addition of other structures, so that the manufacturing cost of the suture assembly is low, and the diameter of the suture assembly can also be reduced, making the suture assembly easy to use in a smaller space.

[0029] 2. The present invention clamps the suture by bringing two rubber pads close to each other, so that the clamping surface becomes larger, thereby achieving a better fixation effect on the suture and making it difficult for the suture to move. Under the action of the self-locking component, the clamping component will not loosen during the clamping process. Anti-slip grooves are also provided on the clamping surface of the rubber pad to increase the friction between the rubber pad and the suture, making it more unlikely that the suture will be pulled during the clamping process, thereby improving the clamping effect of the suture assembly on the suture.

[0030] 3.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] For example 1, please refer to Figures 1 to 9 The present embodiment provides an antibacterial medical suture assembly, including a sleeve 9, the end face of the sleeve 9 is fixedly connected to an end block 5, the end face of the end block 5 is provided with a through groove 7 that penetrates into the interior of the sleeve 9, and a suture 1 is arranged in the groove of the through groove 7.

[0044] The basic material of the suture 1 can be an absorbable polymer material, such as PGLA (polyglycolide-lactide copolymer). This material has good biocompatibility and can be degraded and absorbed by the body over time after implantation into the human body. Therefore, it is widely used in the suturing of various soft tissues.

[0045] The key feature of antibacterial sutures lies in the antibacterial coating on their surface, which may contain broad-spectrum antibacterial agents such as triclosan, which can effectively inhibit the growth of a variety of Staphylococci (such as Staphylococcus aureus, Staphylococcus epidermidis, methicillin-resistant Staphylococcus aureus, and methicillin-resistant Staphylococcus epidermidis).

[0046] The suture assembly also includes a self-locking assembly, which is arranged at the end of the sleeve 9 and includes:

[0047] An externally threaded barrel 28, the end face of the externally threaded barrel 28 being fixedly connected to the end face of the sleeve 9, the end face of the externally threaded barrel 28 facing away from the sleeve 9 being cut to form a cross-section 31, and the remaining portion of the end face of the externally threaded barrel 28 facing away from the sleeve 9 forming a cross-section 32, the end face of the externally threaded barrel 28 facing away from the sleeve 9 being cut to form a longitudinal section 33, and the end face of the externally threaded barrel 28 facing away from the sleeve 9 being cut to form a longitudinal section 27;

[0048] The second external threaded barrel 26 has an end surface facing the first external threaded barrel 28, and a third cross section 35 is cut out of the second external threaded barrel 26. The remaining portion of the end surface facing the first external threaded barrel 28 forms a fourth cross section 34. The second external threaded barrel 26 has an end surface facing the first external threaded barrel 28, and a fourth longitudinal section 30 is cut out of the second external threaded barrel 26. The second external threaded barrel 26 has an end surface facing away from the first external threaded barrel 28, and is fixedly connected to the second end block 2. The end surface of the second end block 2 has a through groove 20 extending through the interior of the second external threaded barrel 26.

[0049] Nut 3, the internal thread of nut 3 is meshed and connected with the thread on the outer surface of external threaded barrel 1 28 and the thread on the outer surface of external threaded barrel 26, and the surface of cross section 1 31 cut on external threaded barrel 1 28 abuts against the surface of cross section 4 34 cut on external threaded barrel 26, and the surface of cross section 2 32 cut on external threaded barrel 1 28 abuts against the surface of cross section 35 cut on external threaded barrel 26, and when the surface of longitudinal section 1 33 cut on external threaded barrel 1 28 fits with the surface of longitudinal section 4 36 cut on external threaded barrel 26, the surface of longitudinal section 2 27 cut on external threaded barrel 1 28 does not fit with the surface of longitudinal section 3 30 cut on external threaded barrel 26, and a cavity 29 is formed between the surface of longitudinal section 2 27 and the surface of longitudinal section 3 30.

[0050] In this embodiment, when using the suture assembly, the suture 1 is passed through the through slot 1 7 provided on the end block 1 5 and the through slot 2 20 provided on the end block 2, and then the nut 3 is rotated to move along the thread grooves on the outer surfaces of the externally threaded barrel 2 26 and the externally threaded barrel 1 28. During the movement, the self-locking assembly has the following two motion states:

[0051] First, when the nut 3 rotates clockwise on the thread grooves on the outer surfaces of the second external threaded barrel 26 and the first external threaded barrel 28, the friction between the threads is greater than the sum of the friction between the cross section 1 31 and the fourth cross section 34 and the friction between the second cross section 32 and the third cross section 35. As a result, the second external threaded barrel 26 is further driven to rotate until the surface of the fourth longitudinal section 36 cut on the second external threaded barrel 26 fits with the surface of the first longitudinal section 33 cut on the first external threaded barrel 28. This prevents the second external threaded barrel 26 from rotating as the nut 3 rotates, further allowing the threads on the first external threaded barrel 28 and the second external threaded barrel 26 to form a complete thread set, thereby not preventing the nut 3 from rotating and moving away from the first external threaded barrel 28.

[0052] Second, when the nut 3 rotates counterclockwise on the thread grooves on the outer surfaces of the second external threaded barrel 26 and the first external threaded barrel 28, the friction between the threads is greater than the sum of the friction between the cross section 1 31 and the fourth cross section 34 and the friction between the second cross section 32 and the third cross section 35. As a result, the second external threaded barrel 26 is also driven to rotate during the rotation. At this time, the third longitudinal section 30 cut on the second external threaded barrel 26 is driven to fit with the second longitudinal section 27 cut on the first external threaded barrel 28, so that the threads on the first external threaded barrel 28 and the second external threaded barrel 26 are staggered, making the nut 3 unable to rotate, thereby preventing the nut 3 from moving toward the first external threaded barrel 28.

[0053] When it is necessary to unlock the self-locking device, it is necessary to press the end faces of the end block 1 5 and the end block 2 2 at the same time, further making the cross section 1 31 and the cross section 4 34 and the cross section 2 32 and the cross section 3 35 fit more tightly, so that when the threads on the externally threaded barrel 1 28 and the externally threaded barrel 2 26 form a complete thread set, the rotation of the nut 3 will not drive the externally threaded barrel 26 to move, and then the nut 3 can be rotated to move toward the externally threaded barrel 1 28, completing the unlocking;

[0054] The arrangement of the present self-locking assembly is such that when the nut 3 rotates outwardly clockwise, the threads on the externally threaded barrel 1 28 and the externally threaded barrel 2 26 form a complete thread group, thereby not preventing the rotation of the nut 3. When the nut 3 rotates counterclockwise, the threads on the externally threaded barrel 1 28 and the externally threaded barrel 2 26 are staggered with each other, preventing the nut 3 from rotating, thereby preventing the nut 3 from moving inward, thereby making the present assembly have a self-locking function. The self-locking method is novel and does not require the addition of other structures, making the manufacturing cost of the present suture assembly low, and the diameter size of the present suture assembly can also be reduced, making the present suture assembly easy to use in a smaller space. The self-locking method can also further improve the safety of the present suture assembly during use, so that the fixing effect of the suture will not be reduced, further improving the practicality of the present suture.

[0055] It is worth noting that this embodiment also includes a clamping assembly, which is arranged in the sleeve 9 and is transmission-connected to the self-locking assembly. The clamping assembly includes:

[0056] The connecting plate 12 has a connecting column 14 fixedly connected to its end. The sleeve 9 has a sliding groove 25 extending therethrough. The wall of the sliding groove 25 is in sliding connection with the surface of the connecting column 14. The end of the connecting column 14 away from the connecting plate 12 is fixedly connected to a sliding ring 11. The inner wall of the sleeve 9 has a groove 13. The surface of the sliding ring 11 is in sliding connection with the wall of the groove 13.

[0057] The fixing ring 10 is arranged inside the sleeve 9 near the end block 5, and the surface of the fixing ring 10 is fixedly connected to the groove wall of the groove 13;

[0058] A curved rod 15 is hinged at one end of the curved rod 15 to the end surface of the sliding ring 11 facing the fixed ring 10. The other end of the curved rod 15 is further hinged to a curved rod 2 19. The end of the curved rod 2 19 away from the curved rod 15 is hinged to the end surface of the fixed ring 10 facing the sliding ring 11. The connecting end of the curved rod 15 and the curved rod 2 19 is further hinged to a fixed plate 1 23. The other end of the fixed plate 1 23 is fixedly connected to a rubber pad 18, and two rubber pads 18 are provided. Two fixed plates 23 are also provided.

[0059] A third curved rod 21 is hinged at one end to the end surface of the sliding ring 11 facing the fixed ring 10. The other end of the third curved rod 21 is further hinged to a fourth curved rod 22. The end of the fourth curved rod 22 away from the third curved rod 21 is hinged to the end surface of the fixed ring 10 facing the sliding ring 11. The connecting end of the fourth curved rod 22 and the third curved rod 21 is hinged to the end of another first fixed plate 23. The end surface of the other first fixed plate 23 is fixedly connected to the end surface of another rubber pad 18.

[0060] A limiting component is provided on the rubber pad 18, and an anti-slip component is also provided on the surface of the rubber pad 18. The limiting component includes a limiting rod 17, the end face of the limiting rod 17 is fixedly connected to the back face of the rubber pad 18, and the surface of the limiting rod 17 is slidably connected to the limiting cylinder 16, and the end face of the limiting cylinder 16 is slidably connected to the groove wall of the groove 13.

[0061] In this embodiment, during the outward movement of the nut 3, the connecting column 14 is further driven to move through the connecting plate 12, so that the connecting column 14 slides on the groove wall of the sliding groove 25, thereby causing the sliding ring 11 to move upward, and since the fixing ring 10 does not move during the entire process, the distance between the sliding ring 11 and the fixing ring 10 will become larger and larger, and the bent curved rod 15 and the curved rod 2 19 as well as the curved rod 3 21 and the curved rod 4 22 will be further straightened, and under the limiting action of the limiting rod 17 and the limiting cylinder 16, the two rubber pads 18 are brought close to each other, thereby clamping the suture 1, and further completing the fixation of the suture assembly to the suture;

[0062] The setting of this clamping assembly clamps the suture 1 by bringing the two rubber pads 18 close to each other, so that the clamping surface becomes larger, thereby achieving a better fixation effect on the suture 1, making it difficult for the suture to move, and under the action of the self-locking assembly, further prevents the clamping assembly from loosening during the clamping process.

[0063] Example 2, based on the above example:

[0064] See also Figure 2 、 Figure 3 and Figure 4 In this embodiment, the anti-skid component includes an anti-skid pattern 24, and the surface of the anti-skid pattern 24 is fixedly connected to the surface of the rubber pad 18;

[0065] In this embodiment, anti-slip grooves 24 are provided on the clamping surface of the rubber pad 18 to increase the friction between the rubber pad 18 and the suture 1, thereby making it less likely that the suture 1 will be pulled during the clamping process, thereby improving the clamping effect of the suture assembly on the suture.

[0066] Example 3, based on the above example:

[0067] See also Figure 1 、 Figure 2 and Figure 6 In this embodiment, a stabilizing component is further included, and the stabilizing component is arranged on the sleeve 9;

[0068] The stabilizing component includes a leather gasket ring 6, the inner wall of which is slidably connected to the outer surface of the sleeve 9, the end face of the leather gasket ring 6 facing the nut 3 is rotatably connected to the end face of the nut 3, the end face of the leather gasket ring 6 facing away from the nut 3 is fixedly connected to a spring 14, the end of the spring 14 away from the leather gasket ring 6 is fixedly connected to a leather gasket ring 28, the inner wall of the leather gasket ring 28 is slidably connected to the outer surface of the sleeve 9, and the end face of the leather gasket ring 28 facing away from the spring 14 is rotatably connected to the end of the end block 15.

[0069] In this embodiment, since the self-locking assembly is formed by fitting the longitudinal section 30 cut on the second external threaded barrel 26 with the longitudinal section 27 cut on the first external threaded barrel 28, the threads on the first external threaded barrel 28 and the second external threaded barrel 26 are staggered with each other, and further, during the self-locking process, the second external threaded barrel 26 still has space for self-locking at one end. The provision of the spring 1 4 can provide a supporting force for the nut 3, thereby further improving the ability of the nut 3 to resist external interference and further improving the stability of the suture assembly during use.

[0070] By setting the spring 1 4, a supporting force can be provided to the nut 3, thereby further improving the ability of the nut 3 to resist external interference, thereby improving the stability of the suture assembly during use.

[0071] Working Principle: When using the antibacterial medical suture assembly, the following steps are involved:

[0072] S1: Pass the suture thread 1 through the through slot 1 7 provided on the end block 1 5 and the through slot 2 20 provided on the end block 2;

[0073] S2: Then, the nut 3 and the connecting plate 12 are rotated to move the connecting column 14, which further moves the sliding ring 11 and the fixing ring 10 away from each other, so that the two rubber pads 18 are brought closer to each other, clamping the suture 1 to complete the fixation of the suture;

[0074] S3: After the suture is fixed, the suture assembly can be left on the patient's body;

[0075] S4: After being left on the patient's body, the self-locking component will take effect, reducing the possibility of the nut 3 rotating due to misoperation and causing the suture assembly to loosen. In addition, under the action of spring 1 4, the ability of the nut 3 to resist external interference is improved, further improving stability.

[0076] S5: When the patient needs to remove the suture assembly after recovery, the end faces of end block 1 5 and end block 2 2 are pressed simultaneously to increase the friction between cross section 1 31 and cross section 4 34 and between cross section 2 32 and cross section 3 35, thereby causing the nut 3 to rotate counterclockwise, causing the two rubber pads 18 to move away from each other, thereby releasing the fixation of the suture.

[0077] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
