Description

Technical Field

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

Background Art

[0002] As modern medical technology develops increasingly, the requirements for surgery are also evolving towards smaller incisions and minimally invasive surgeries, which can not only achieve a rapid and good wound recovery 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, the surgeon holds a suture needle equipped with surgical suture in hand, sutures the tissues on both sides of the wound, and forms 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 wind the surgical suture by hand to form a fixed knot, and the binding process is complicated. Also, due to the small incision, the operation of winding the surgical suture by hand is hindered, leading to a decline in the quality of the fixed knot. When forming multiple fixed knots at the wound in the above knotting method, not only will the overall time become longer and inefficient, but if the fixed knots are not properly tied, the wound will be easily torn, 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 suturing of wounds in surgery, it is necessary to repeatedly form multiple fixed knots at the wound one by one, which not only makes the overall surgery time longer and inefficient, but also if the small knots are not properly tied, the wound will be easily torn, affecting the patient's recovery efficiency. This problem is overcome.

[0009] In the capsule needle thread module of the present invention, the knotting member is provided with a position-regulating hole at its front end, a position-regulating string protrudes from the front end through the position-regulating hole, at least a portion of the position-regulating string protruding from the position-regulating hole forms a position-regulating ring, and at least a portion of the position-regulating ring and the pre-knot or the movable ring are hooked onto each other.

[0010] In the capsule needle thread module of the present invention, the through hole and the position regulating hole are provided in the knotting member parallel to each other and communicate with the groove. The position regulating string is recessed into the position regulating hole, with both ends protruding into the groove, forming the position regulating ring at the recessed portion of the position regulating string, which protrudes toward the front end of the position regulating hole and hooks with the pre-knot, and when the operation control member connects with the connection portion, at least a part of the operation control member presses both ends of the position regulating string between the connection portion.

[0011] In the capsule needle thread module of the present invention, the knotting member includes the contact structure which includes an extended portion extending from any surface of the knotting member to the front end, the front end of the extended portion which extends radially in accordance with the through hole, and the outer circumference of the end of the outer fitting shaft which protrudes from the through hole and the end face of the contact portion which come into contact with each other.

[0012] The capsule needle thread module of the present invention includes a shell that covers at least a portion of the front end of the operation control member and at least a portion of the rear end of the knotting member, a thread puller rod is formed at the front end of the operation control member, one end of the suture thread is tied to the thread puller rod, an operation control unit is formed at a portion of the rear end of the operation control member that protrudes from the shell, the operation control unit and the thread puller rod are connected via a connecting rod, the connecting portion extends to the position of the operation control unit at the rear end of the knotting member, at least a portion of the connecting portion and at least a portion of the front end of the operation control member are installed overlapping each other within the case, the front end of the operation control member slides within the shell relative to the connecting portion, and the connecting portion has a radially recessed engagement groove on one side surface of the operation control member.

[0013] In the capsule needle thread module of the present invention, the operating control member has a connecting rib that extends in accordance with the connection portion, and the connecting rib and the connecting rod are installed with a gap between them, and the front end of the connecting rib fits into the shell and an engaging projection protrudes toward the engaging groove.

[0014] Furthermore, the end of the suture thread exposed from the capsule needle module is connected to the suture needle.

[0015] Furthermore, the operation control member includes a thread puller installed in the radial direction, and one end of the suture thread is tied to the thread puller.

[0016] Furthermore, the two connecting ribs are formed by extending from both ends of the threading rod toward the front end, and the suture thread is tied and secured to the threading rod by passing sequentially through the through hole, the groove, and between the two connecting ribs.

[0017] Furthermore, at least a portion of the outer fitting shaft protruding from the through hole is a binding portion, and the length of the binding portion changes according to the relative position displaced along the through hole of the outer fitting shaft.

[0018] Furthermore, the outer diameter of the connecting member gradually decreases from the rear end to the front end, forming a tapered shape.

[0019] When operating the capsule needle module, the operator aligns the front end of the knotting member with the expected suture location, passes the suture needle through the suture location, and then passes the suture thread along with the suture thread through the movable ring. After suturing is complete, the operator operates the operation control member to separate it from the knotting member and pulls the suture thread through the operation control member to contract the movable ring until it adheres to the outer circumference of the outer fitting shaft.

[0020] Next, the operation control member is continued to be pulled, and / or the suture needle is continued to be pulled synchronously, generating tension at both ends of the suture, detaching the pre-knot from the outer fitting shaft, and binding it with the movable ring and the suture that has passed through the movable ring, thereby forming a fixed knot. [Effects of the Invention]

[0021] Compared to conventional technology, 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 complete the continuous suturing and knotting processes in a narrow space, optimizes the surgical process and the quality of suturing and knotting, and on the premise of increasing the length, the capsule needle and thread module maximally reduces the usage fee of the suture to achieve the effect of cost reduction.

[0022] [[ID=!3]] The abutting structure assists the operator to align the capsule needle and thread module with the suture site, and avoids the outer fitting shaft from directly contacting the suture site and being contaminated by blood or tissue fluid. At the same time, when the abutting structure is supported by the outer fitting shaft, it can effectively avoid the prenot from unexpectedly detaching from the outer fitting shaft

[0023] Particularly, when the outer fitting shaft is fixedly installed in the through hole, in 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 abutting structure on the prenot to make it detach from the outer fitting shaft. In this process, the abutting structure avoids the prenot from detaching from the outer fitting shaft first, and further avoids the situation that the position of the fixed knot becomes non-ideal or the quality of the fixed knot is not good and it is easy to loosen.

[0025] To further clarify the purpose, technical proposal and advantages of the embodiments of the present invention, the technical proposal of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention, however, the embodiments described are some embodiments of the present invention, not all embodiments. Those skilled in the art will know that all other embodiments based on the embodiments of the present invention, performed without creative labor, are all within the scope of the protection of the present invention.

[0026] Figures 1 to 3b show a first preferred embodiment of a capsule needle module provided by the present invention, which includes an axially arranged operating control member 10 and a knotting member 20, the operating control member 10 being located at the rear end and the knotting member 20 being located at the front end. The knotting member 20 is provided with a through hole 21 through which a suture A can be passed, and the operating end of the suture A is connected to any part of the operating control member 10. The method by which the suture A is connected to the operating control member 10 is not limited and may be by adhesive fixation or knotting, and in this embodiment the operating control member 10 includes a radially positioned thread puller 12, and the operating end of the suture A can be tied to the thread puller 12.

[0027] An outer fitting shaft 22 protruding from the front end is installed in the through hole 21 of the knotting member 20, and the outer fitting shaft 22 is hollow tubular. The other end of the suture A opposite to the operating end is the suture end, and after passing through the through hole 21 and the outer fitting shaft 22 at the suture end, the suture A extends toward the front end and is exposed outside the capsule needle module. The suture end of the suture A that is exposed outside the capsule needle module is wrapped around the outer circumference of the outer fitting shaft 22, forming a pre-knot A1 and a movable ring A2 formed between the outer fitting shaft 22 and the pre-knot A1, and the suture A is used to suture and fix a tissue wound with a suture needle B connected to the end of the suture end.

[0028] In the first embodiment, at least a portion of the outer fitting shaft 22 is fixedly installed within the through hole 21. When operating the capsule needle module, the operator aligns the front end of the knotting member 20 with the expected suture location and passes it through the movable ring A2. Furthermore, during suturing, a suture different from suture A may be used and passed through the movable ring A2. After suturing is complete, the operator operates the operation control member 10 to separate it from the knotting member 20 and pulls the operating end of suture A through the operation control member 10, thereby shrinking the movable ring A2 until at least a portion of it is attached to the outer circumference of the outer fitting shaft 22. Next, the operation control member 10 is continued to be pulled, and / or the suture needle B is continued to be pulled synchronously, generating tension at both ends of the suture A, detaching the pre-knot A1 from the outer fitting shaft 22, and binding it with the movable ring A2 and the suture A that has passed through the movable ring A2, thereby forming a fixed knot.

[0029] In another embodiment, the outer fitting shaft 22 can be displaced along the through hole 21, and the length protruding from the front end of the through hole 21 varies depending on its position relative to the through hole 21. At least a portion of the outer fitting shaft 22 protruding from the through hole 21 is further defined as a binding portion 221. When the operation control member 10 is continuously pulled, the movable ring A2 is pulled and contracted, pressing and moving the outer fitting shaft 22 into the through hole 21, and when the outer fitting shaft 22 is fully inside the through hole 21, the pre-knot A1 detaches from the outer fitting shaft 22 and binds to the movable ring A2 and the suture A passing through the movable ring A2, forming the fixed knot.

[0030] In another embodiment, the tying member 20 includes a connecting portion 23, which is detachably coupled to the operation control member 10 to prevent the operation control member 10 from being moved in an unexpected manner. The method by which the connecting portion 23 of the tying member 20 and the operation control member 10 are coupled is not limited. It may be by a combination of protrusions and indentations, or a coupling member may be installed between the connecting portion 23 and the operation control member 10 to detachably combine them.

[0031] In this embodiment, a groove 231 is recessed at the rear end of the tying member 20 as a connection portion 23, and at least a portion of the inner wall of the groove 231 is recessed with an annular engagement portion 232 in the radial direction. The operating control member 10 has two connecting ribs 11 that extend toward the front end and are spaced apart and arranged in correspondence, and the longest distance between the two connecting ribs 11 is slightly smaller than the diameter of the groove 231. The operating control member 10 is removably inserted into the groove 231 of the tying member 20 using the two connecting ribs 11. Preferably, the groove 231 of the tying member 20 is connected to the rear end of the through hole 21, and the two connecting ribs 11 are formed by extending from both ends of the thread puller 12 of the operating control member 10 toward the front end, so that the operating end of the suture A can be sequentially passed through the through hole 21, the groove 231, and the gap between the two connecting ribs and tied to the thread puller 12.

[0032] At the front ends of the two connecting ribs 11, the portions corresponding to the engagement portions 232 have engagement projections 111 that protrude radially. When the two connecting ribs 11 are placed in the groove 231, the engagement projections 111 are housed within the engagement portions 232, and the operation control member 10 cannot be detached from the connecting member 20 due to the concave-concave coupling relationship between the engagement projections 111 and the engagement portions 232.

[0033] For example, when pulling the operation control member 10 away from the knotting member 20 during operation, pressure is applied to the two connecting ribs 11 to bring them closer together and deform them, causing the engaging protrusions 111 to disengage from the grooves and release the concave-convex coupling relationship, allowing the operation control member 10 to detach from the knotting member 20. The capsule needle and suture module of the present invention has a simple structure and can effectively reduce the overall volume to make it suitable for minimally invasive surgery, assisting the operator in completing suturing and knotting procedures continuously in confined spaces, and optimizing the surgical process and the quality of suturing and knotting.

[0034] Next, referring to the second preferred embodiment shown in Figure 4, the difference from the first embodiment is that the knotting member 20 further includes a position regulating hole 24 at its front end, the position regulating string C protrudes toward the front end within the position regulating hole 24, and a position regulating ring C1 is formed on at least a portion of the position regulating string C protruding from the position regulating hole 24, and at least a portion of the position regulating ring C1 is hooked with the pre-knot A1 and / or the movable ring A2 to prevent the pre-knot A1 and the movable ring A2 from detaching from the outer fitting shaft 22 in unexpected circumstances.

[0035] In this embodiment, the through hole 21 and the position regulating hole 24 are provided in the knotting member 20 parallel to each other, and the rear ends of the through hole 21 and the position regulating hole 24 are connected by the groove 231. The position regulating string C is recessed into 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 the recess protrudes toward the front end of the position regulating hole 24 and is hooked with the pre-knot A1. When the operation control member 10 is connected to the connection portion 23 of the knotting member 20 with corresponding protrusions and recesses, at least a part of the operation control member 10 presses both ends of the position regulating string C between the connection portion 23. In this manner, the position control string C releases the operation control member 10 when it is necessary to detach it from the knotting member 20 again, releasing the pre-knot A1, and then forming the fixed knot.

[0036] Furthermore, referring to Figures 5 to 7b, a third preferred embodiment provided by the present invention includes an operating control member 10, the knotting member 20, and a shell 30, wherein the shell 30 covers at least a portion of the front end of the operating control member 10 and at least a portion of the rear end of the knotting member 20. The difference from the embodiments described above is that the capsule needle module is substantially rod-shaped, and the design of this embodiment maximizes the reduction in the amount of suture A used, assuming an increase in the length of the capsule needle module, and achieves cost reduction by designing the capsule needle module in different sizes as needed.

[0037] The operation control member 10 is rod-shaped, and a thread puller 12, which is connected to the operating end of the suture A, is formed at its front end. The front end of the operation control member 10 can slide within the shell 30 relative to the knotting member 20, and an operation control unit 13 is formed at the rear end of the operation control member 10 that protrudes from the shell 30, and the operator operates the operation control unit 13 to pull the operation control member 10 relative to the knotting member 20.

[0038] The capsule needle module further includes a connection portion 23, the position in which the connection portion 23 is formed is not limited, and any structure or member that is installed between the knotting member 20 and the operation control member 10, or between the shell 30 and the operation control member 10, and that can detachably fix the operation control member 10 and prevent it from detaching from the knotting member 20, is within the scope of the present invention.

[0039] Preferably, the connecting portion 23 extends from the rear end of the connecting member 20 and is housed within the shell 30, and at least a portion of the connecting portion 23 and at least a portion of the front end of the operation control member 10 are installed overlapping each other within the shell 30. The connecting portion 23 may be the groove 231 or a rail, and the front end of the operation control member 10 can slide within the shell 30 relative to the connecting portion 23.

[0040] In this embodiment, the connection portion 23 extends toward the rear end to a position adjacent to the operation control unit 13, and an engagement groove 235 is recessed radially on the side of the connection portion 23 corresponding to the operation control member 10. The operation control unit 13 extends toward the front end and includes a connecting rod 131 and a connecting rib 11, and the connecting rod 131 and the connecting rib 11 are installed corresponding to each other with a gap between them, and the position of the connecting rib 11 corresponds to the connection portion 23.

[0041] The front end of the connecting rod 131 is deeply inserted into the shell 30 and connected to the threading rod 12, and the front end of the connecting rib 11 is deeply inserted into the shell 30 and an engaging projection 111 protrudes toward the engaging groove 235. In this way, the operation control unit 10 cannot be detached from the knotting member 20 due to the concave-concave coupling relationship between the engaging projection 111 and the engaging portion 232. When the operation control unit 10 is to be detached from the knotting member 20, pressure is applied to deform the connecting rib 11 and move toward the connecting rod 131, causing the engaging projection 111 to detach from the groove 231 and releasing the concave-concave coupling relationship.

[0042] In another embodiment, the outer diameter of the knotting member 20 gradually decreases from the rear end to the front end to form a tapered shape, and when the capsule needle module corresponds to the suture site by the knotting member 20, the tapered structure can avoid interfering with the operator's field of view and helps the capsule needle module confirm the corresponding position of the front end of the knotting member 20.

[0043] In another embodiment, a contact structure 25 is formed at the front end of the knotting member 20, and a accommodating space 26 is formed between the contact structure 25 and the front end of the knotting member 20. Preferably, the contact structure 25 has an extension portion 251 that extends toward the front end via one of the surfaces of the front end of the knotting member 20, and a contact portion 252 that extends corresponding to the radial direction of the through hole 21 at the front end of the extension portion 251. The space between the extension portion 251, the contact 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 extension portion 251.

[0044] When not in use, the lengths of the outer shaft 22 and the binding portion 221 are preferably equal to the length of the housing space 26. Preferably, at least a portion of the outer circumference of the end of the binding portion 221 is supported by the contact portion 252, thereby reinforcing the overall structure. Furthermore, the outer circumference of the end of the binding portion 221 and the end face of the contact portion 252 are in contact with each other. The contact structure 25 can assist the operator in aligning the capsule needle module with the suture site, and the outer shaft 22 avoids direct contact with the suture site and contamination by blood or tissue fluid. At the same time, the contact structure 25 can effectively prevent the pre-knot A1 from unexpectedly detaching from the outer shaft 22 when supported by the outer shaft 22.

[0045] In the embodiment in which the outer fitting shaft 22 is fixedly installed within the through hole 21, during the process of forming the fixing knot, the operator needs to obtain sufficient tension to deform the contact structure 25 by pressing it against the pre-knot A1 and causing it to detach from the outer fitting shaft 22 when pulling the operation control member 10 and / or the suture B. In this process, the contact structure 25 prevents the pre-knot A1 from detaching from the outer fitting shaft 22 first, and also prevents situations in which the position of the fixing knot becomes unideal or the quality of the fixing knot is poor and it easily loosens.

[0046] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the rights claimed by the present invention. All other equivalent modifications or changes that do not depart from the spirit disclosed herein should be included within the scope of the claims of the present invention. [Explanation of symbols]
