Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-3 Description of a meniscus suture device according to an embodiment of the present invention.

[0029] This utility model proposes a meniscus suture device, which includes a support rod 10, an operating part, a first engaging part 30, and a second engaging part 40. The support rod 10 forms a first suture channel 11 and a second suture channel 12. The first engaging part 30 and the second engaging part 40 are disposed at one end of the support rod 10. The interior of the first engaging part 30 forms a third suture channel 31 that can be selectively connected to the first suture channel 11, and the first engaging part 30 is provided with a suture outlet 32 ​​that communicates with the third suture channel 31. The interior of the second engaging part 40 forms a fourth suture channel 41 that can be selectively connected to the second suture channel 12, and the second engaging part 40 is provided with a... A return port connected to the fourth lead channel 41; at least one of the first engagement portion 30 and the second engagement portion 40 is movably connected to the support rod 10 to allow the outlet port 32 and the return port to selectively approach or move away from each other; wherein when the first engagement portion 30 and the second engagement portion 40 stop, the first lead channel 11, the third lead channel 31, the fourth lead channel 41 and the second lead channel 12 are sequentially connected to allow the suture to pass through; an operating part is provided at the other end of the support rod 10, and the operating part is linked with at least one of the first engagement portion 30 and the second engagement portion 40, and the operating part is adapted to drive the first engagement portion 30 and / or the second engagement portion 40 to approach or move away from each other under the action of external force.

[0030] According to the meniscus suture device of this application, the operating part can be used for gripping and performing operations; the support rod 10 can be inserted into the surgical site through a puncture or surgical incision; the first occlusal part 30 and the second occlusal part 40 are disposed at one end of the support rod 10 and can be inserted into the surgical site along with the support rod 10; at least one of the first occlusal part 30 and the second occlusal part 40 is movably connected to the support rod 10, so when the first occlusal part 30 and / or the second occlusal part 40 rotate relative to the support rod 10, the first occlusal part 30 and the second occlusal part 40 can move closer or further apart, and when rotated to a certain angle, the first occlusal part 30 and the second occlusal part 40 stop, at which time the first occlusal part 30 and the second occlusal part 40 can bite and hold the tissue to be sutured. Furthermore, the support rod 10 forms a first lead wire channel 11 and a second lead wire channel 12. The interior of the first engagement part 30 forms a third lead wire channel 31 that can be selectively connected to the first lead wire channel 11. The interior of the second engagement part 40 forms a fourth lead wire channel 41 that can be selectively connected to the second lead wire channel 12. When the first engagement part 30 and the second engagement part 40 stop, the inlet 42 and the outlet 32 ​​are directly opposite each other. The first lead wire channel 11, the third lead wire channel 31, the fourth lead wire channel 41 and the second lead wire channel 12 are connected in sequence. At this time, the suture can be inserted into the first lead wire channel 11 by external operation. Continuing to push the suture can make it move along the first lead wire channel 11, the third lead wire channel 31, the fourth lead wire channel 41 and the second lead wire channel 12, and extend out from the second lead wire channel 12. At this time, the suture can pass through the tissue to be sutured.

[0031] When using the meniscus suture device of this application, the support rod 10 drives the first occlusal part 30 and the second occlusal part 40 to be inserted into the surgical site through a puncture or surgical incision; the first occlusal part 30 and / or the second occlusal part 40 are moved to occlude the tissue to be sutured; the suture is threaded through the first guide channel 11, the third guide channel 31, the fourth guide channel 41, and the second guide channel 12 and passes through the tissue to be sutured; the first occlusal part 30 and / or the second occlusal part 40 are moved to release the tissue to be sutured, and the support rod 10 is moved out of the surgical site. At this time, the suture is still passing through the tissue to be sutured, and the suture is tied to complete the suturing process.

[0032] According to the meniscus suture device of this application, a suture channel can be established to pass through the tissue to be sutured. The suture channel is connected to the outside of the body, which facilitates the process of threading the suture outside the body, thus simplifying the suturing operation. It can be completed in one hand operation. In addition, since the structure of the first occlusal part 30 and the second occlusal part 40 can rotate flexibly, they can accurately occlude the meniscus tissue, avoid involving other tissues, improve the surgical effect, and reduce surgical side effects.

[0033] According to some embodiments of this application, the first occlusal portion 30 has a first bend extending toward the second occlusal portion 40, and the end of the first bend is provided with a suture outlet 32; the second occlusal portion 40 has a second bend extending toward the first occlusal portion 30, and the end of the second bend is provided with a suture return port. When the first bend and the second bend are abutted, they are aligned in the extension direction to facilitate communication between the suture outlet 32 ​​and the suture return port. In this embodiment, by forming a first bend extending toward the second occlusal portion 40 in the first occlusal portion 30 and a second bend extending toward the first occlusal portion 40 in the second occlusal portion 40, the first occlusal portion 30 and the second occlusal portion 40 can more easily penetrate the tissue to be sutured; furthermore, since the suture outlet 32 ​​is located at the end of the first bend and the suture return port is located at the end of the second bend, the extension directions of the third suture channel 31 and the fourth suture channel 41 are closer, which is more conducive to the suture passing through each suture channel.

[0034] According to some embodiments of this application, a first mating portion 33 is formed at the end of the first engagement portion 30 near the support rod 10. The first mating portion 33 has an inlet communicating with the third lead wire channel 31. The wall of the first lead wire channel 11 has a second mating portion 13 that mates with the first mating portion 33. The second mating portion 13 has an outlet communicating with the first lead wire channel 11. When the first engagement portion 30 and the second engagement portion 40 abut, the first mating portion 33 and the second mating portion 13 are engaged and connected, and the inlet and outlet are connected. In this embodiment, by engaging the first mating portion 33 and the second mating portion 13, the third lead wire channel 31 inside the first engagement portion 30 and the first lead wire channel 11 inside the support rod 10 can be aligned and connected, so as to ensure that the suture can pass through smoothly.

[0035] According to some embodiments of this application, the first engaging portion 30 is rotatably disposed on the support rod 10, and at least a portion of the surface of the first mating portion 33 is constructed as an arc surface centered on the rotation center of the first engaging portion 30, and at least a portion of the surface of the second mating portion 13 is constructed as a concave surface that mates with the arc surface. In this embodiment, the arc surface of the first mating portion 33 is centered on the rotation center of the first engaging portion 30, and the concave surface of the second mating portion 13 mates with the arc surface, enabling the first mating portion 33 and the second mating portion 13 to fit tightly together when facing each other without affecting the rotation of the first engaging portion 30, avoiding gaps and ensuring that the suture thread passes through smoothly.

[0036] According to some embodiments of this application, the inner diameters of the outlet 32 ​​and / or return outlet gradually increase in the direction toward each other. In this embodiment, the gradual increase in the inner diameter of the outlet 32 ​​and / or return outlet in the direction toward each other can prevent the suture from being blocked from entering the fourth lead channel 41 due to a positional deviation between the outlet 32 ​​and the return outlet when passing through the connection between the third lead channel 31 and the fourth lead channel 41. This embodiment can address the deviation problem that may occur in actual operation and ensure that the suture passes smoothly through the lead channel.

[0037] According to some embodiments of this application, the operating part includes a handle 21 and a linkage 22; the handle 21 is rotatably disposed at the other end of the support rod 10; the linkage 22 is disposed on the support rod 10, one end of the linkage 22 is connected to the handle 21, and the other end of the linkage 22 is connected to the first engagement part 30. In this embodiment, the first engagement part 30 is controlled to rotate relative to the support rod 10 by the handle 21, making the operation more convenient; the linkage 22 connects the handle 21 and the first engagement part 30, enabling the driving operation to be completed over a longer distance.

[0038] In some embodiments, the meniscus suture device further includes a retaining handle 50, which is disposed on the support rod 10. The handle 21 and the retaining handle 50 are rotatably connected to each other so as to facilitate operation by holding the device with one hand.

[0039] According to some embodiments of this application, the support rod 10 forms a limiting portion 14, and the linkage member 22 is slidably connected to the limiting portion 14 to restrict the movement of the linkage member 22 along the extending direction of the support rod 10. In this embodiment, the support rod 10 and the limiting portion 14 cooperate to slide relative to the support rod 10, which can make the driving process more stable.

[0040] In some embodiments, based on the needs of surgical operation, the support rod 10 is constructed as a tubular structure, and the first lead wire channel 11, the second lead wire channel 12, and the limiting part 14 are all disposed in the cavity inside the support rod 10.

[0041] According to some embodiments of this application, the meniscus suture device further includes a first connecting rod 23 and a second connecting rod 24; one end of the first connecting rod 23 is rotatably connected to the linkage member 22, and the other end of the first connecting rod 23 is rotatably connected to the first engaging part 30, and the first connecting rod 23 is adapted to be driven by the linkage member 22 to drive the first engaging part 30 to rotate; one end of the second connecting rod 24 is rotatably connected to the linkage member 22, and the other end of the second connecting rod 24 is rotatably connected to the operating part, and the second connecting rod 24 is adapted to be driven by the operating part to drive the linkage member 22 to slide along the extension direction of the support rod 10. In this embodiment, by setting the second connecting rod 24, the rotation of the handle 21 can be converted into the sliding of the linkage member 22 relative to the support rod 10, and by setting the first connecting rod 23, the sliding of the linkage member 22 relative to the support rod 10 can be converted into the rotation of the first engaging part 30 relative to the support rod 10. This embodiment achieves motion transmission through a simple structure, making the operation and control of the first engaging part 30 smoother and more convenient.

[0042] According to some embodiments of this application, the linkage 22 is constructed as a flexible component. In this embodiment, the linkage 22 is constructed as a flexible component, and by pulling the linkage 22 with the handle 21, the first engaging part 30 can be rotated relative to the support rod 10; since the linkage 22 is flexible, its own structural characteristics can be used to avoid mutual interference between structures during motion transmission.

[0043] According to some embodiments of this application, the meniscus suture device further includes an elastic element 60, which is disposed between the handle 21 and the support rod 10, and / or between the first engaging portion 30 and the wall surface of the support rod 10. In this embodiment, by providing the elastic element 60, the meniscus suture device can be restored to its original structural form when the external force is removed.
