Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a soft tissue repair implantation device. Background Technology

[0002] Rotator cuff tendon tears are a common cause of shoulder pain, limited range of motion, and functional impairment. Rotator cuff tendon tears lead to a range of shoulder inflammations and affect the quality of daily life, such as shoulder pain, which can cause difficulty sleeping at night, difficulty combing hair, and female patients' inability to remove their bras.

[0003] Currently, the repair of rotator cuff tendon tears generally involves implanting a device to fix the tear site. The implant is inserted using a device, typically through tapping or screwing. This procedure requires not only a high level of skill from the surgeon but also a certain amount of force, increasing the surgical risk. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a soft tissue repair implant device to solve the technical problem that when rotator cuff tendon tears are repaired by implantation and fixation, the implantation process usually involves tapping, screwing and other operations, which are difficult to control in terms of operation techniques and manipulation force, thus increasing surgical risks.

[0005] To achieve the above objectives, the present invention provides a soft tissue repair implantation device, comprising a housing, a pressing handle, a transmission mechanism, and an implantation rod assembly. The pressing handle is disposed on the housing, and the transmission mechanism is disposed inside the housing. The pressing handle is connected to the transmission mechanism through the housing. The implantation rod assembly is disposed at one end of the housing and extends into the housing and is connected to the transmission mechanism. When the pressing handle is pressed, the implantation rod assembly completes the implantation action. When the pressing handle is released, the implantation rod assembly retracts, and the implant on the implantation rod assembly disengages.

[0006] According to a preferred embodiment, the transmission mechanism includes a linkage transmission assembly and a misalignment transmission assembly, both of which are installed inside the housing. One end of the linkage transmission assembly is driven to the pressing handle, and the other end is driven to the misalignment transmission assembly. The misalignment transmission assembly is also driven to the implanted rod assembly.

[0007] According to a preferred embodiment, the linkage transmission assembly includes at least two transmission rods connected end to end, with the end of the transmission rod simultaneously hinged to the pressing handle and the misaligned transmission assembly, and adjacent transmission rods being hinged to each other.

[0008] According to a preferred embodiment, the transmission rod includes three rods: a first straight rod, a second straight rod, and a right-angle rod. The first straight rod is hinged to the pressing handle, the right-angle rod is hinged to both the first straight rod and the second straight rod, and the second straight rod is hinged to the misaligned transmission assembly.

[0009] According to a preferred embodiment, the transmission rod includes two rods, namely a curved rod and a third straight rod. The angle range of the curved rod is 30°-90°. One end of the curved rod is hinged to the pressing handle, and the other end is hinged to the third straight rod. The third straight rod is hinged to the misaligned transmission assembly.

[0010] According to a preferred embodiment, the misalignment transmission assembly includes a push block, a first push slider, and a second push slider. One end of the push block is hinged to the linkage transmission assembly, and the other end simultaneously contacts the first push slider and the second push slider, for pushing the first push slider and the second push slider to slide. The end of the first push slider opposite to the push block is provided with a first elastic element, and the end of the second push slider opposite to the push block is provided with a second elastic element. The first push slider resets before the second push slider.

[0011] According to a preferred embodiment, the end of the second push slider that contacts the push block is provided with a stepped structure, the stepped structure is provided with a limiting block, and the end of the limiting block away from the stepped structure is provided with a third elastic element. The limiting block causes the second push slider to reset later than the first push slider through the elastic force of the third elastic element.

[0012] According to a preferred embodiment, the first push slider is provided with a protrusion, and the second push slider is provided with a preset channel adapted to the protrusion. When the first push slider retracts, it drives the protrusion to slide in the preset channel, triggering the limiting block to compress the third elastic member.

[0013] According to a preferred embodiment, the implant rod assembly includes a rod housing and an implant rod head. One end of the rod housing is mounted on the outer shell, and the other end of the rod housing is provided with the implant rod head. The rod housing contains a first implant rod, a second implant rod, a first straight implant rod, and a second straight implant rod. One end of the first implant rod is connected to the first push slider, and the other end is connected to the first straight implant rod. One end of the second implant rod is connected to the second push slider, and the other end is connected to the second straight implant rod.

[0014] According to a preferred embodiment, the head of the implant rod is pointed.

[0015] According to a preferred embodiment, the free end of the first straight implant rod is provided with two parallel guide rails.

[0016] According to a preferred embodiment, the free ends of the first straight implant rod and the second straight implant rod are provided with mutually communicating arc-shaped grooves.

[0017] The soft tissue repair implant device provided by this invention has the following technical effects:

[0018] The invented soft tissue repair implant device allows for implantation of the implant rod assembly when the handle is pressed. When the handle is released, the implant rod assembly retracts, and the implant detaches from the assembly. Pressing the handle activates the transmission mechanism within the housing, which in turn activates the implant rod assembly. This process is precise and effortless. Compared to existing technologies that use tapping or screwing, this device offers more precise operation and reduces surgical risks.

[0019] In addition, the misalignment-driven method allows for rapid implantation and detachment of the implant, simplifying the overall implantation procedure and reducing surgical risks. Attached Figure Description

[0035] 5. Implants. Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] Current techniques for repairing rotator cuff tendon tears typically involve implanting a device to fix the tear. The implant is inserted using a device, usually through tapping or screwing. This procedure requires not only a high level of skill from the surgeon but also a certain amount of force, increasing the surgical risk.

[0038] To address the aforementioned shortcomings, the following section provides specific details. Figure 1-9The implantation device according to a preferred embodiment of the present invention will be described in detail.

[0039] like Figure 1 The diagram shown is a schematic diagram of the implantation device of the present invention. The implantation device is used to implant soft tissue repair implants 5. It includes a shell 1, a pressing handle 2, a transmission mechanism 4, and an implantation rod assembly 3. One end of the pressing handle 2 is hinged to the shell 1, and the other end is hinged to the transmission mechanism 4. The transmission mechanism 4 is installed inside the shell 1. The implantation rod assembly 3 is installed outside the shell 1, and its end extends into the shell 1 and is connected to the transmission mechanism 4 for transmission.

[0040] When the pressing handle 2 is pressed manually, the transmission mechanism 4 drives the implant rod assembly 3 to move forward (here, forward means moving away from the pressing handle 2). During the forward movement of the implant rod assembly 3, the implantation of the implant 5 is completed. When the pressing handle 2 is released, the transmission mechanism 4 drives the implant rod assembly 3 to move backward (here, backward means moving closer to the pressing handle 2). During the backward movement of the implant rod assembly 3, the implant 5 is disengaged from the implantation device.

[0041] The following is a detailed description of the structure of the transmission mechanism 4 and the implant rod assembly 3.

[0042] like Figure 2 and 6 As shown in Figure 9, the transmission mechanism 4 includes a linkage transmission assembly 41 and a misalignment transmission assembly 42. Both the linkage transmission assembly 41 and the misalignment transmission assembly 42 are installed inside the housing 1. One end of the linkage transmission assembly 41 is driven to the pressing handle 2, and the other end is driven to the misalignment transmission assembly 42. The misalignment transmission assembly 42 is also driven to the implanted rod assembly 3.

[0043] Furthermore, such as Figure 6-9 As shown, the linkage transmission assembly 41 includes at least two transmission rods, and in this embodiment, it preferably includes three rods, namely a first straight rod 411, a second straight rod 413, and a right-angle rod 412. The first straight rod 411 is hinged to the pressing handle 2, and both ends of the right-angle rod 412 are simultaneously hinged to the first straight rod 411 and the second straight rod 413. The second straight rod 413 is hinged to the push block 421. The right angle of the right-angle rod 412 is fixed inside the outer casing 1, and the two free extension sides are hinged to the first straight rod 411 and the second straight rod 413.

[0044] Pressing or releasing the handle 2 sequentially rotates the first straight rod 411, the right-angle rod 412, and the second straight rod 413, thereby causing the push block 421 to move back and forth.

[0045] It should be noted that the linkage transmission assembly 41 of the present invention may also include two transmission rods, namely a bending rod and a third straight rod. The angle range of the bending rod is 30°-90°. One end of the bending rod is hinged to the pressing handle 2, and the other end is hinged to the third straight rod. The third straight rod is hinged to the push block 421. The push block 421 can also be moved back and forth through the bending rod and the third straight rod.

[0046] Furthermore, such as Figure 6-9 As shown, the misaligned transmission assembly 42 includes a push block 421, a first push slider 422, and a second push slider 423. One end of the push block 421 is hinged to the second straight rod 413, and the other end is in contact with both the first push slider 422 and the second push slider 423 (initially, the first push slider 422 and the second push slider 423 are arranged side by side). During the back-and-forth movement of the push block 421, it can push the first push slider 422 and the second push slider 423 to slide. The end of the first push slider 422 opposite to the push block 421 is provided with a first elastic element 424, and the end of the second push slider 423 opposite to the push block 421 is provided with a second elastic element 425.

[0047] In this embodiment, both the first elastic element 424 and the second elastic element 425 are preferably springs. One end of the first elastic element 424 is in contact with the first push slider 422, and the other end is fixed to the inside of the outer shell 1. During the movement of the first push slider 422, the first elastic element 424 can be deformed. One end of the second elastic element 425 is in contact with the second push slider 423, and the other end is also fixed to the inner wall of the outer shell 1. During the movement of the second push slider 423, the second elastic element 425 can be deformed.

[0048] To achieve the reset of the first push slider 422 before the second push slider 423, or the reset of the second push slider 423 after the reset of the first push slider 422, the end of the second push slider 423 that contacts the push block 421 is further provided as a stepped structure 4231. In the initial state, the limiting block 426 is located on the upper surface of the stepped structure 4231. The end of the limiting block 426 away from the stepped structure 4231 is provided with a third elastic element 427. The limiting block 426 uses the elastic force of the third elastic element 427 to make the second push slider 423 reset later than the first push slider 422.

[0049] Similarly, the third elastic element 427 of the present invention is preferably a spring. One end of the third elastic element 427 is fixed on the inner wall of the outer shell 1, and the other end is in contact with the upper surface of the stepped structure 4231. The limiting block 426 moves toward the third elastic element 427, which can compress the third elastic element 427. The elastic force accumulated by the third elastic element 427 can also push the limiting block 426 to move.

[0050] In addition, the first push slider 422 is provided with a protrusion 4221, and the second push slider 423 is provided with a preset channel. The preset channel and the protrusion 4221 cooperate. When the first push slider 422 retracts, it drives the protrusion 4221 to slide in the preset channel. During the movement of the protrusion 4221, the limiting block 426 is triggered to compress the third elastic member 427, and the limiting block 426 falls into the lower surface of the stepped structure 4231.

[0051] In this embodiment, the limiting block 426 cooperates with the stepped structure 4231 of the second pushing slider 423 to limit the front-back position of the second pushing slider 423. The third elastic member 427 can limit the vertical return of the limiting block 426.

[0052] Since the first elastic element 424 and the second elastic element 425 are connected to the first push slider 422 and the second push slider 423, when the implantation process of the implant 5 ends, the first push slider 422 and the second push slider 423 are respectively returned to their original positions, which in turn causes the first implant rod 33 and the second implant rod 34 to return to their original positions, and then causes the first straight implant rod 35 and the second straight implant rod 36 to return to their original positions.

[0053] like Figure 1-5 As shown, the implant rod assembly 3 of the present invention includes a rod housing 31 and an implant rod head 32. The rod housing 31 has a cylindrical structure. One end of the rod housing 31 is mounted on the outer shell 1, and the other end of the rod housing 31 is provided with the implant rod head 32. The rod housing 31 is provided with a first implant rod 33, a second implant rod 34, a first straight implant rod 35, and a second straight implant rod 36. One end of the first implant rod 33 is connected to a first push slider 422, and the other end is connected to the first straight implant rod 35. One end of the second implant rod 34 is connected to a second push slider 423, and the other end is connected to the second straight implant rod 36.

[0054] like Figure 3 As shown, the free end of the first straight implant rod 35 is provided with two parallel guide rails 37 and 38, and the free end of the first straight implant rod 35 and the free end of the second straight implant rod 36 are provided with mutually communicating arc-shaped grooves, which cooperate with the arc-shaped structure at the tail end of the implant 5.

[0055] Among them, such as Figure 4 As shown, the implantation rod head 32 is pointed, and the pointed implantation rod head 32 can play a guiding role in the implantation process.

[0056] It should be noted that the cross-section of the guide rails 37 and 38 in this embodiment is preferably quadrilateral. This structure is adapted to the implant 5, and the two quadrilateral guide rails 37 and 38 are connected to the first straight implant rod 35.

[0057] The cross-section of the guide rails 37 and 38 is not limited to a quadrilateral; it can also be a triangular, pentagonal, hexagonal, circular, etc. This invention does not limit it in this respect.

[0058] like Figure 7 The diagram shows the structure of the implantation device during the implantation process. Pressing the handle 2 causes the first straight rod 411, the right-angle rod 412, and the second straight rod 413 to move in tandem, which in turn pushes the push block 421 forward. The push block 421 moves forward together and contacts the tail of the first push slider 422 and the second push slider 423, causing the first push slider 422 and the second push slider 423 to move forward. As the first push slider 422 and the second push slider 423 move forward, they simultaneously compress the first elastic element 424 and the second elastic element 425 connected to them, which also drives the first implantation rod 33, the second implantation rod 34, the first straight implantation rod 35, and the second straight implantation rod 36 to move forward. This step completes the implantation process of the implant 5.

[0059] like Figure 8 The diagram shows the structure of the implantation device after implantation. When the handle 2 is released, the first elastic element 424 and the second elastic element 425, due to their rebound action, push the first push slider 422 and the second push slider 423 in the opposite direction. This causes the first straight rod 411, the right-angle rod 412, the second straight rod 413, and the push block 421 to move back to their initial positions in conjunction. The handle 2 then returns to its original position. Due to the action of the third elastic element 427, the limiting block 426 cooperates with the stepped structure 4231 to provide a limiting effect. During the retraction of the first push slider 422, the protrusion 4221 on the first push slider 422 interacts with the limiting block 4231. When the positioning block 426 contacts, it overcomes the elastic force of the third elastic element 427, causing the limiting block 426 to disconnect from the stepped contact at the tail end, pushing the tail end of the limiting block 426 back to its original position. At the same time, due to the rebound effect of the second elastic element 425, the second pushing slider 423 drives the second implantation rod 34 and the second straight implantation rod 36 to retract. In the whole process, the first implantation rod 33 and the first straight implantation rod 35 retract to their original positions one step ahead of the second implantation rod 34 and the second straight implantation rod 36. This staggered retraction results in the implant 5 being able to smoothly detach from the guide rail 38 after implantation, achieving the purpose of the implant 5 remaining in the soft tissue area.

[0060] like Figure 9 The diagram shows the internal state of the implantation device after implantation of implant 5. After releasing the handle, all components inside the outer shell 1 and the rod housing 31 return to their initial state, preparing for the implantation of the next implant 5.

[0061] In the description of the present invention, it should be noted that, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
