Description

Technical Field

[0001] The present invention relates to a sewing needle thread, and particularly to a capsule needle thread module.

Background Art

[0002] As modern medical technology develops more and more, the requirements for surgery are also evolving towards smaller incisions and minimally invasive surgeries, which can not only achieve a quick and good wound healing effect, but also help with the disappearance and improvement of the scar after healing. In the prior art, when a surgeon wants to suture a wound, usually, a suture needle equipped with a surgical suture is held in the hand, and the tissues on both sides of the wound are sutured to form a fixed knot to fix the end of the surgical suture.

[0003] However, in the above prior art, it is necessary for the surgeon to manually wind the surgical suture to form a fixed knot, the binding process is complicated, and also, due to the small incision, the operation of manually winding the surgical suture is hindered, leading to a decrease in the quality of the fixed knot. When forming a plurality of fixed knots at the wound in the above knotting method, not only does the overall time become long and inefficient, but if the fixed knots are not properly tied, the wound is likely to split easily, affecting the patient's recovery efficiency.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When applying the conventional thread knotting technology to the suture of a wound in surgery, it is necessary to repeatedly form a plurality of fixed knots one by one at the wound, which not only makes the overall operation time long and inefficient, but also if the small knots are not properly tied, the wound is likely to split easily, affecting the patient's recovery efficiency. This problem is overcome.

Means for Solving the Problems

[0005] The present invention provides a capsule needle and thread module including a knot member provided with a through hole, a front end and a rear end defined at both ends of the through hole, and a hollow tubular outer fitting shaft protruding toward the front end of the through hole, and a suture thread having an operating end and a suturing end at both ends, passing through the through hole and the outer fitting shaft, and the operating end and the suturing end being exposed at the rear end of the through hole and the front end of the outer fitting shaft, respectively.

[0006] In the capsule needle and thread module of the present invention, at least a part of the suturing end of the suture thread is wound around the outer periphery of the outer fitting shaft to form a pre-knot, and a movable ring is formed between the outer fitting shaft and the pre-knot. A knot structure is formed at the rear end of the knot member at least at a part of the operating end of the suture thread. The size of the movable ring changes based on the distance by which the knot structure moves relative to the knot member.

[0007] In the capsule needle and thread module of the present invention, the diameter formed by the knot structure is larger than the diameter formed by the through hole, and the knot structure is abutted against the rear end of the through hole by the knot member.

[0008] In the capsule needle and thread module of the present invention, the knot structure is a spherical knot, or the knot structure includes a spherical knot and a pull ring connected to the rear end of the knot.

[0009] In the capsule needle and thread module of the present invention, the knot member includes a large-diameter portion formed at the rear end of the through hole, the diameter formed by the large-diameter portion is equal to or smaller than the knot structure, and at least a part of the knot member is removably housed in the large-diameter portion.

[0010] In the capsule needle and thread module of the present invention, at least a part protruding from the through hole of the outer fitting shaft is a binding part, and the length of the binding part changes according to the relative position displaced along the through hole of the outer fitting shaft. During suturing, at least a part of the suture thread is passed through the movable ring. The movable ring is reduced by pulling until it adheres to the outer periphery of the outer fitting shaft. As the movable ring continues to be reduced, it pushes the outer fitting shaft and moves it toward the inside of the through hole. The length of the binding part is gradually reduced. When the outer fitting shaft completely enters the through hole, the plennut detaches from the outer fitting shaft and is bound to at least a part of the movable ring and the suture thread to form the fixed knot.

[0011] In the capsule needle and thread module of the present invention, at least a part of the outer fitting shaft is fixedly installed in the through hole. During suturing, at least a part of the suture thread is passed through the movable ring. The movable ring is reduced by pulling until it adheres to the outer periphery of the outer fitting shaft. By continuously pulling the operation control member, the plennut moves toward the front end until it detaches from the outer fitting shaft. When the plennut detaches from the outer fitting shaft, it is bound to at least a part of the movable ring and the suture thread to form the fixed knot.

[0012] Furthermore, the suturing end of the suture thread is connected to a suture needle.

[0013] During the operation of the capsule needle and thread module, the operator aligns the front end of the knot member with the expected suturing location. After passing the suturing location using the suture needle, the operator passes the suture thread along with the suture needle through the movable ring. After the suturing is completed, the operator operates the operation control member to release it from the knot member and pulls the suture thread through the operation control member to reduce the movable ring until it adheres to the outer periphery of the outer fitting shaft.

[0014] Next, continue to hold the operation control member and / or continuously pull the suture needle synchronously to generate tension at both ends of the suture thread, detach the pre-knot from the outer fitting shaft, bind it with the movable ring and the suture thread passing through the movable ring, and form a fixed knot.

Advantages of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows. The capsule needle and thread module of the present invention has a simple structure, can be designed in different sizes as required, can be reduced to be suitable for minimally invasive surgery, assists the operator to continuously complete the suture and knotting processes in a narrow space, optimizes the surgical process and the quality of suture and knotting, and the capsule needle and thread module can achieve the effect of cost reduction by maximizing the reduction of the usage fee of the suture thread on the premise of increasing the length.

[0016] The contact structure assists the operator to align the capsule needle and thread module with the suture location, and avoids the outer fitting shaft directly contacting the suture location and being contaminated by blood or tissue fluid. At the same time, when the contact structure is supported by the outer fitting shaft, it can effectively avoid the pre-knot detaching from the outer fitting shaft in an unexpected state.

[0017] In particular, when the outer fitting shaft is fixedly installed in the through hole, during the process of forming the fixed knot, when the operator pulls the operation control member and / or the suture thread, it is necessary to obtain sufficient tension to press and deform the contact structure on the pre-knot to detach it from the outer fitting shaft. In this process, the contact structure avoids the pre-knot detaching from the outer fitting shaft first, and further avoids the occurrence of a situation where the position of the fixed knot is not ideal or the quality of the fixed knot is not good and it is easily loosened.

Modes for Carrying Out the Invention

[0019] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, hereinafter, in combination with the drawings in the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described. However, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments made by those skilled in the art without creative labor fall within the protection scope of the present invention.

[0020] Figs. 1 to 3b show the first preferred embodiment of the capsule needle and thread module provided by the present invention, including an operation control member 10 and a tying member 20 arranged axially. The operation control member 10 is installed at the rear end, and the tying member 20 is installed at the front end. The tying member 20 is provided with a through hole 21 through which a suture A can pass, and the operation end of the suture A is connected to any part of the operation control member 10. The method of connecting the suture A to the operation control member 10 is not limited and may be adhesive fixation or binding fixation. In this embodiment, the operation control member 10 includes a thread pulling rod 12 installed radially, and the operation end of the suture A can be tied to the thread pulling rod 12.

[0021] An externally fitted shaft 22 protruding from the front end is installed in the through hole 21 of the tying member 20. The externally fitted shaft 22 is hollow and tubular. The other end opposite to the operation end of the suture A is a suture end. The suture A passes through the through hole 21 and the externally fitted shaft 22 at the suture end and then extends toward the front end and is exposed outside the capsule needle and thread module. The suture end of the suture A exposed outside the capsule needle and thread module is wound around the outer periphery of the externally fitted shaft 22, forming a pre-knot A1 and a movable ring A2 formed between the externally fitted shaft 22 and the pre-knot A1. The suture A is connected with a suture needle B at the end of the suture end and is used for suturing and fixing tissue wounds.

[0022] In the first embodiment, at least a part of the externally fitted shaft 22 is fixedly installed in the through hole 21. When operating the capsule needle thread module, the operator aligns the front end of the tying member 20 with the suture position to be expected and passes it through the movable ring A2. Further, at the time of suturing, suturing may be performed using another suture different from the suture A and passed through the movable ring A2. After the suturing is completed, the operator operates the operation control member 10 to separate it from the tying member 20, pulls the operating end of the suture A through the operation control member 10, and reduces the movable ring A2 until at least a part of the movable ring A2 is attached to the outer periphery of the externally fitted shaft 22. Next, continue to operate the operation control member 10 and / or continue to pull the suture needle B synchronously to generate tension at both ends of the suture A, detach the prenot A1 from the externally fitted shaft 22, and bundle it with the movable ring A2 and the suture A that has passed through the movable ring A2 to form a fixed knot.

[0023] In another embodiment, the externally fitted shaft 22 can be displaced along the through hole 21, and the length protruding from the front end of the through hole 21 is changed according to the position relative to the through hole 21. At least a part of the externally fitted shaft 22 protruding from the through hole 21 is further defined as a bundling portion 221. When continuously pulling the operation control member 10, the movable ring A2 is pulled and reduced, the externally fitted shaft 22 is pressed and moved into the through hole 21, and when the externally fitted shaft 22 completely enters the through hole 21, the prenot A1 is detached from the externally fitted shaft 22 and bundled with the movable ring A2 and the suture A passing through the movable ring A2 to form the fixed knot.

[0024] In another embodiment, the tying member 20 includes a connection portion 23, and the connection portion 23 is detachably coupled to the operation control member 10 to prevent the operation control member 10 from being pulled in an unexpected state. The method of coupling the connection portion 23 of the tying member 20 and the operation control member 10 is not limited. It may be by a combination of unevenness, or a coupling member may be installed between the connection portion 23 and the operation control member 10 and detachably combined.

[0025] In this embodiment, a groove 231 is recessed at the rear end of the connecting member 20 as a connecting portion 23, and at least a part of the inner wall of the groove 231 has an engaging portion 232 recessed in an annular shape in the radial direction. The operation control member 10 is formed with two connecting ribs 11 that extend toward the front end and are installed at intervals corresponding to each other, and the longest distance formed between the two connecting ribs 11 is slightly smaller than the diameter of the groove 231. And the operation control member 10 removably enters into the groove 231 of the connecting member 20 by using the two connecting ribs 11. Preferably, the groove 231 of the connecting member 20 communicates with the rear end of the through hole 21, and the two connecting ribs 11 are formed by extending from both ends of the thread pulling rod 12 of the operation control member 10 toward the front end, and the operation end of the suture A can be sequentially tied and fixed to the thread pulling rod 12 through the through hole 21, the groove 231 and the gap between the two connecting ribs.

[0026] At the location corresponding to the engaging portion 232 at the front ends of the two connecting ribs 11, an engaging convex portion 111 protrudes in the radial direction. When the two connecting ribs 11 are installed in the groove 231, the engaging convex portion 111 is correspondingly received in the engaging portion 232, and the operation control member 10 cannot be separated from the connecting member 20 due to the concave-convex coupling relationship between the engaging convex portion 111 and the engaging portion 232.

[0027] For example, during operation, when pulling the operation control member 10 away from the connecting member 20, pressure is applied to the two connecting ribs 11 to make them approach each other and deform, so that the engaging convex portion 111 is disengaged from the groove to release the concave-convex coupling relationship, and the operation control member 10 can be separated from the connecting member 20. The capsule needle and thread module of the present invention has a simple structure, can effectively reduce the overall volume to be suitable for minimally invasive surgery, assist the operator to complete continuous suturing and knotting procedures in a narrow space, and can optimize the surgical process and the quality of suturing and knotting.

[0028] Next, referring to the second preferred embodiment shown in FIG. 4, the difference from the first embodiment is that the connecting member 20 further includes a position regulating hole 24 at the front end, and the position regulating string C protrudes toward the front end within the position regulating hole 24. At least a part of the position regulating string C protruding from the position regulating hole 24 forms a position regulating ring C1, and at least a part of the position regulating ring C1 is hooked with the prenot A1 and / or the movable ring A2, preventing the prenot A1 and the movable ring A2 from detaching from the externally fitted shaft 22 in an unexpected situation.

[0029] In this embodiment, the through hole 21 and the position regulating hole 24 are provided in the connecting member 20 parallel to each other, and the rear ends of the through hole 21 and the position regulating hole 24 are both communicated by the groove 231. The position regulating string C is installed recessed within the position regulating hole 24, and both ends of the position regulating string C protrude into the groove 231 toward the rear end of the position regulating hole 24. The position regulating ring C1 formed after being recessed protrudes toward the front end of the position regulating hole 24 and is hooked with the prenot A1. When the operation control member 10 is coupled to the connection part 23 of the connecting member 20 with corresponding concavities and convexities, at least a part of the operation control member 10 presses both ends of the position regulating string C between the connection parts 23. In this way, the position regulating string C releases when the operation control member 10 needs to be detached from the connecting member 20 again, releases the prenot A1, and then forms the fixed knot.

[0030] Furthermore, referring to FIGS. 5 to 7b, the third preferred embodiment provided by the present invention includes an operation control member 10, the connecting member 20, and a shell 30. The shell 30 covers at least a part of the front end of the operation control member 10 and at least a part of the rear end of the connecting member 20. The difference from each of the foregoing embodiments is that the capsule needle and thread module is substantially rod-shaped. With the design of this embodiment, on the premise of increasing the length of the capsule needle and thread module, the usage amount of the suture A is reduced to the maximum, and the capsule needle and thread module is designed in different sizes as required to achieve the effect of cost reduction.

[0031] The operation control member 10 is rod-shaped, and at its front end, a thread pulling rod 12 connected to the operation end of the suture A is formed. The front end of the operation control member 10 can slide within the shell 30 relative to the knotting member 20, and at the location where the rear end of the operation control member 10 protrudes from the shell 30, an operation control portion 13 is formed. The operator operates the operation control portion 13 to pull the operation control member 10 relative to the knotting member 20.

[0032] The capsule needle and thread module further includes a connection site 23. The position where the connection site 23 is formed is not limited. Whether it is installed between the knotting member 20 and the operation control member 10 or between the shell 30 and the operation control member 10, any structure or member that removably fixes the operation control member 10 and can prevent it from detaching from the knotting member 20 is included within the scope of the present invention.

[0033] Preferably, the connection site 23 extends from the rear end of the knotting member 20 and is accommodated within the shell 30, and at least a part of the connection site 23 and at least a part of the front end of the operation control member 10 overlap and are installed with each other within the shell 30. The connection site 23 may be the groove 231 or a rail, and the front end of the operation control member 10 can be slid within the shell 30 relative to the connection site 23.

[0034] In this embodiment, the connection site 23 extends to a position adjacent to the operation control portion 13 toward the rear end. On the side surface of the connection site 23 corresponding to the operation control member 10, an engagement groove 235 is recessed in the radial direction. The operation control portion 13 extends toward the front end and includes a connection rod 131 and a connection rib 11. The connection rod 131 and the connection rib 11 are installed corresponding to each other with a space therebetween, and the position of the connection rib 11 corresponds to the connection site 23.

[0035] The front end of the connecting rod 131 extends deeply into the shell 30 and is connected to the thread pulling rod 12. The front end of the connecting rib 11 extends deeply into the shell 30, and the engaging convex portion 111 protrudes toward the engaging groove 235. In this way, the operation control unit 10 cannot be detached from the knot member 20 due to the concave-convex coupling relationship between the engaging convex portion 111 and the engaging portion 232. When detaching the operation control member 10 from the knot member 20, pressure is applied to deform the connecting rib 11 and move it toward the connecting rod 131, so that the engaging convex portion 111 can be detached from the groove 231 and the concave-convex coupling relationship can be released.

[0036] In another embodiment, the outer diameter of the knot member 20 gradually decreases from the rear end to the front end to form a tapered shape. When the capsule needle thread module corresponds to the suturing position by the knot member 20, the tapered structure can avoid interfering with the operator's field of view and assist in confirming the corresponding position at the front end of the knot member 20 for the capsule needle thread module.

[0037] In another embodiment, an abutting structure 25 is formed at the front end of the knot member 20, and an accommodating space 26 is formed between the abutting structure 25 and the front end of the knot member 20. Preferably, the abutting structure 25 has an extending portion 251 extending forward through any surface at the front end of the knot member 20, and an abutting portion 252 extending corresponding to the radial direction of the through hole 21 at the front end of the extending portion 251. The extending portion 251, the abutting portion 252 and the through hole 21 can define the accommodating space 26, and the size of the accommodating space 26 can be defined by the length of the extending portion 251.

[0038] When not in use, the length of the outer fitting shaft 22 and the bundling portion 221 is preferably equal to the length of the accommodation space 26. Preferably, at least a part of the outer periphery of the end of the bundling portion 221 is supported by the abutting portion 252, strengthening the overall structure. Further, the outer periphery of the end of the bundling portion 221 abuts against the end face of the abutting portion 252. The abutting structure 25 can assist the operator in aligning the capsule needle and thread module with the suture site, and the outer fitting shaft 22 can avoid direct contact with the suture site and being contaminated by blood or tissue fluid. At the same time, when supported by the outer fitting shaft 22, the abutting structure 25 can effectively prevent the pre-knob A1 from detaching from the outer fitting shaft 22 unexpectedly.

[0039] In the embodiment where the outer fitting shaft 22 is fixedly installed in the through hole 21, during the process of forming the fixed knot, when the operator pulls the operation control member 10 and / or the suture thread B, it is necessary to obtain sufficient tension to press and deform the abutting structure 25 against the pre-knob A1 to make it detach from the outer fitting shaft 22. In this process, the abutting structure 25 prevents the pre-knob A1 from detaching from the outer fitting shaft 22 first, and further avoids the situation where the position of the fixed knot becomes non-ideal or the quality of the fixed knot is not good and it is likely to loosen easily.

[0040] Furthermore, referring to FIGS. 8a and 8b, FIGS. 8a and 8b are respectively the fourth and fifth preferred embodiments provided by the present invention. The difference from the above embodiments is that the operating member 10 is formed by the operating end of the suture thread A. In the embodiments shown in FIGS. 8a and 8b, the capsule needle and thread module includes the knotting member 20, and a through hole 21 is also provided in the knotting member 20. Further, taking both ends of the through hole 21 as the front end and the rear end, a hollow cylindrical outer fitting shaft 22 projects into the through hole 21 toward the front end. Since the relationship between the outer fitting shaft 22 and the through hole 21 has been described above, the description will not be repeated here.

[0041] The suture A passes through the through hole and the outer fitting shaft, and both ends thereof become the operation end and the suture end, respectively. The operation end of the suture A is exposed at the rear end of the through hole 21, and the suture end is exposed at the front end of the outer fitting shaft 22. Similarly, at least a part of the suture end of the suture A is wound around the outer periphery of the outer fitting shaft 22 to form the pre-knot A1, and the movable ring A2 is formed between the outer fitting shaft 22 and the pre-knot.

[0042] At least a part of the operation end located at the rear end of the knot member 20 of the suture A forms a knot structure A3 as the operation control member 10. In this way, the size of the movable ring A2 can be changed directly based on the distance that the knot structure A3 moves relative to the rear end of the knot member 20, and the structure of the operation control member 10 described in the above embodiments of the present invention can be omitted, achieving the effect of miniaturization and being applicable to minimally invasive surgeries such as laparoscopic surgery and da Vinci surgery.

[0043] In the embodiment shown in FIG. 8a, the knot structure A3 is a spherical knot A31 formed at the end of the operation end. The diameter preferably formed by the knot A31 is larger than the diameter of the through hole 21, so that the through hole 21 cannot pass through the knot structure A3, and the knot member 20 abuts against the rear end of the through hole 21. In this way, during use, the knot A31 can be directly pulled to move the movable ring A2 to shrink, and finally the fixed knot is formed.

[0044] In the embodiment shown in FIG. 8b, the difference from FIG. 8a is that the knot structure A3 includes the spherical knot A31 and the pull ring A32. In this embodiment, when forming the knot structure A3, first, any part of the operating end of the suture A is recessed, the end of the operating end and at least a part of the operating end of the suture A are overlapped and arranged, and the end of the operating end and at least a part of the operating end are used together to form the knot A31. At the same time when the knot A31 is formed, the recessed part of the operating end of the suture A can further define the pull ring A32. In this way, during use, a tool such as an instrument is used to hook the pull ring A32, pull the knot structure A3, improve the convenience and accuracy during operation, and prevent slipping through when pulling.

[0045] The knot structure A3 can be provided in various forms as required. For example, a cross bar or a soft annular body is bound to the knot A31, and on the premise of easily inserting the capsule needle thread module into the body by minimally invasive incision, the knot structure A3 is pulled to achieve the effect of facilitating the formation of the fixed knot.

[0046] To avoid a situation where the knot structure A3 is pulled in an unexpected situation and the movable ring A2 shrinks, making it difficult for the suture needle B and the suture end of the suture A to pass through the movable ring during suturing, the knot member 20 has a large-diameter portion 211 formed at the rear end of the through hole 21, and the knot structure A3 can be accommodated in the large-diameter portion 211.

[0047] Preferably, the diameter formed by the large-diameter portion 211 is equal to or smaller than that of the knot A31, and the knot structure A3 is accommodated in the large-diameter portion 211 by the knot A31. During storage, the knot A31 can generate frictional force with at least a part of the side wall of the large-diameter portion 211, and the pull ring A32 is exposed at the rear end of the large-diameter portion 211. In this way, the knot structure A3 is accommodated in the large-diameter portion 211 and is difficult to come off. Furthermore, even if the knot structure A3 and / or the pull ring A32 are accidentally pulled, the knot structure A3 can be prevented from being displaced relative to the knot member 20 and the movable ring A2 from being unexpectedly reduced.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the scope of the rights claimed by the present invention. Any other equivalent changes or modifications that do not depart from the spirit disclosed in the present invention should be included within the scope of the claims of the present invention.
