Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more particularly to an implant. Background Technology
[0002] With the rapid development of minimally invasive endoscopic techniques in clinical practice, an increasing number of joint surgeons are choosing minimally invasive methods to treat joint diseases. Arthroscopic surgery involves creating one or more incisions outside the patient's body and inserting one or more cannulated instruments through these small incisions to perform surgical procedures within the confined space of the body. For example, in cases of tendon injuries, to enhance repair and promote tendon healing, surgeons often implant a biological or synthetic patch at the site of the tendon tear using an implanter. However, in minimally invasive surgery, there is a pressing need to address the reliability of implants and the cumbersome procedures involved. Summary of the Invention
[0003] This application provides an implanter designed to improve the ease of operation of the implanter.
[0004] Embodiments of this application provide an implanter, including: an implantation part, a clamping part, an opening and closing assembly, a cannula assembly, and a driving part. An implantation part extends along a first direction and includes a proximal end and a distal end arranged opposite to each other along the first direction; a clamping part includes a clamping arm, which is located at the distal end and is used to clamp the material to be implanted; an opening and closing assembly includes an unfolding arm, which is located at the distal end; a cannula assembly is sleeved on the outside of the implantation part and is movably located at the distal end along the first direction, and is used to wrap the clamping arm, the unfolding arm, and the material to be implanted, with an opening at the end of the cannula assembly facing away from the proximal end; a driving part is located at the proximal end and includes a housing, within which are arranged a first rotating member, a second rotating member, a third rotating member, a first connecting member, a second connecting member, and a third connecting member, the first connecting member being wound around the first rotating member and connected to the clamping arm, the first rotating member being used to drive the clamping arm to clamp the material to be implanted, the second connecting member being wound around the second rotating member and connected to the cannula assembly, the second rotating member being used to drive the cannula assembly to move in a direction away from the distal end, and the third connecting member being wound around the third rotating member and connected to the unfolding arm, the third rotating member being used to drive the unfolding arm to unfold.
[0005] According to the embodiments of this application, the second rotating member and the third rotating member are arranged side by side along the second direction. The housing is provided with a driving gear and a transmission gear that mesh with each other. The driving part also includes a first trigger, which meshes with the driving gear to drive the driving gear to rotate. The transmission gear is located on the side of the driving gear close to the second and third rotating members. The transmission gear is movably arranged along the second direction so that the transmission gear can switch between meshing with the second rotating member and the third rotating member. The first direction and the second direction intersect.
[0006] According to an embodiment of this application, a first trigger is located outside the housing and extends into the housing. The first trigger is used to drive the drive gear to rotate in a first rotation direction, so as to drive the second rotating member and the third rotating member to rotate in the first rotation direction through the transmission gear. The second rotating member rotates in the first rotation direction and wraps around the second connecting member to drive the sleeve assembly to move in the direction away from the distal end. The third rotating member rotates in the first rotation direction and wraps around the third connecting member to drive the unfolding arm to unfold. The implant also includes a first anti-rotation member, which is located inside the housing. The first anti-rotation member abuts against the drive gear to limit the drive gear from rotating in the opposite direction of the first rotation direction.
[0007] According to the embodiments of this application, the housing has first mounting holes on both sides along the second direction, and the transmission gear has connecting rods on both sides along the second direction. The two ends of the connecting rods are respectively installed in the two first mounting holes, and the two ends of the connecting rods are exposed through the first mounting holes. The connecting rods are configured to move the transmission gear along the second direction by pressing the connecting rods.
[0008] According to embodiments of this application, the implanter further includes a cutting assembly comprising a blade located within a housing, the blade being movably configured to cut at least one of the first connector, the second connector, and the third connector.
[0009] According to an embodiment of this application, the housing has a first groove extending along a third direction, and the cutting assembly includes a cutting button located outside the housing. The cutting button is movably mounted in the first groove along a third direction. The cutting button is connected to the blade through the first groove. The first connector, the second connector, and the third connector are located on the same side of the blade along the third direction, and the first direction and the third direction intersect.
[0010] According to an embodiment of this application, an accommodating cavity is provided inside the implantation part, the accommodating cavity penetrates the implantation part along a first direction, the proximal end of the implantation part extends into the housing, the accommodating cavity is connected to the housing, a first connector is connected to the clamping arm through the accommodating cavity from the proximal end, a third connector is connected to the unfolding arm through the accommodating cavity from the proximal end, and a second connector is located outside the implantation part and extends along the outer wall of the implantation part from the proximal end to the distal end, and is connected to the cannula assembly.
[0011] According to an embodiment of this application, the cutting surface formed by the blade moving along a third direction is disposed adjacent to the proximal end of the implanted portion along a first direction.
[0012] According to an embodiment of this application, the implanter further includes a second trigger extending from outside the housing to inside the housing. The second trigger is used to drive the first rotating member to rotate in a second rotation direction. The first rotating member rotates in the second rotation direction to wrap around the first connecting member to drive the clamping arm to clamp the material to be implanted.
[0013] According to an embodiment of this application, the implanter further includes a second anti-rotation member located within the housing. The second anti-rotation member is movably disposed and includes an anti-rotation spring. The second anti-rotation member is moved such that the anti-rotation spring abuts against the first rotating member to restrict the first rotating member from rotating in the opposite direction of the second rotation direction. The second anti-rotation member is moved such that the anti-rotation spring is spaced apart from the first rotating member, and the first rotating member can rotate in the opposite direction of the second rotation direction to release the material to be implanted.
[0014] According to an embodiment of this application, the second trigger is provided with a second ratchet, which is movably connected to the second trigger and extends toward the first rotating member. The end of the second ratchet near the first rotating member has a latch. The second anti-rotation member further includes a release plate, which abuts against the latch to actuate the second ratchet and disengage it from the first rotating member. The release plate and the anti-rotation spring are synchronously movable to allow the first rotating member to switch between a first state and a second state. In the first state, both the anti-rotation spring and the second trigger abut against the first rotating member, and the first rotating member can rotate in the second rotation direction. In the second state, the anti-rotation spring is spaced apart from the first rotating member, and the release plate actuates the latch until the second ratchet is spaced apart from the first rotating member, allowing the first rotating member to rotate in the opposite direction of the second rotation direction.
[0015] In the embodiments of this application, a first connector is wound around a first rotating member and connected to a clamping arm. The first rotating member rotates to wind around the first connector, and the first connector moves toward the direction away from the distal end, thereby driving the clamping arm to clamp the material to be implanted. During the process of the clamping arm extending to the rotator cuff tear location, the clamping arm holds the patch and extends into the human body. When the clamping arm reaches the rotator cuff tear location, the clamping arm releases the patch. A cannula assembly is located at the distal end. After the patch is rolled up, it is held in a rolled-up state by the clamping arm. The clamping arm holds the patch and extends into the cannula assembly. During the process of the clamping arm holding the patch and extending it through a small incision in the human body to the rotator cuff tear location, the cannula assembly separates the human tissue from the patch and the clamping arm, reducing the compression and friction between the patch and the human tissue during the process of the patch entering the human body, thus preventing it from detaching from the clamping arm. Furthermore, the tubular structure of the cannula assembly helps to reduce the friction between the patch and the human tissue, ensuring that the patch smoothly enters the rotator cuff tear location. The cannula assembly has an opening at its proximal end. A second connector is wound around a second rotating member and connected to the cannula assembly. The second rotating member rotates and winds around the second connector, causing the second connector to move away from the distal end, pulling the cannula assembly synchronously in that direction. The clamping arm and patch detach from the cannula assembly through the opening, and then the clamping arm releases the patch. A third rotating member rotates and winds around the third connector, pulling the unfolding arm away from the distal end. Once the unfolding arm has unfolded and flattened the patch, subsequent surgical steps can be performed. By using the first rotating member to wind around the first connector, the second rotating member to wind around the second connector, and the third rotating member to wind around the third connector, the clamping, detachment, and flattening operations can be achieved, simplifying the operation process, significantly shortening the surgical time, reducing the complexity of the drive components, saving costs, and improving the reliability of the implant.

[0022] like Figures 1 to 5 As shown in the embodiment of this application, an implanter includes: an implantation part 100, a clamping part 200, an opening and closing component 400, a cannula component 300, and a driving part 500. An implantation portion 100 extends along a first direction X and includes a proximal end 101 and a distal end 102 disposed opposite to each other along the first direction X. A clamping portion 200 includes a clamping arm 210 disposed at the distal end 102 and used to clamp the material 10 to be implanted. An opening / closing assembly 400 includes an unfolding arm 410 disposed at the distal end 102 and located within a cannula assembly 300. A cannula assembly 300 is sleeved on the outside of the implantation portion 100 and is movably disposed at the distal end 102 along the first direction X. The cannula assembly 300 is used to wrap the clamping arm 210 and the unfolding arm 410, and has an opening 301 at the end of the cannula assembly 300 facing away from the proximal end 101. A driving portion 500 is disposed at the proximal end 101 and drives... The part 500 includes a housing 510, within which are disposed a first rotating member 520, a second rotating member 530, a third rotating member 540, a first connecting member 521, a second connecting member 531, and a third connecting member 541. The first connecting member 521 is wound around the first rotating member 520 and connected to the clamping arm 210. The first rotating member 520 is used to drive the clamping arm 210 to clamp the material 10 to be implanted. The second connecting member 531 is wound around the second rotating member 530 and connected to the cannula assembly 300. The second rotating member 530 is used to drive the cannula assembly 300 to move in a direction away from the distal end 102. The third connecting member 541 is wound around the third rotating member 540 and connected to the unfolding arm 410. The third rotating member 540 is used to drive the unfolding arm 410 to unfold.
[0023] In this embodiment, the distal end 102 of the implantation unit 100 is oriented towards and enters the rotator cuff tear through a small incision made in the human skin. The clamping part 200 includes a clamping arm 210, which is disposed at the distal end 102 and is used to clamp the material to be implanted 10, which can be a patch. The first connecting member 521 is wound around the first rotating member 520 and connected to the clamping arm 210. The first rotating member 520 rotates and wound around the first connecting member 521. The first connecting member 521 moves in a direction away from the distal end 102, thereby driving the clamping arm 210 to clamp the material to be implanted 10. During the process of the clamping arm 210 extending to the rotator cuff tear position, the clamping arm 210 clamps the patch and extends into the human body. When the clamping arm 210 reaches the rotator cuff tear position, the clamping arm 210 releases the patch.
[0024] The cannula assembly 300 is located at the distal end 102. After the patch is rolled up, it is held in a rolled-up state by the clamping arm 210. The clamping arm 210 holds the patch and extends it into the cannula assembly 300. As the clamping arm 210 holds the patch and extends it through a small incision in the human body to the rotator cuff tear, the cannula assembly 300 separates the human tissue from the patch and the clamping arm 210, reducing the compression and friction between the patch and the human tissue during the insertion process, thus preventing the patch from detaching from the clamping arm 210. Furthermore, the tubular structure of the cannula assembly 300 helps to reduce the friction between the patch and the human tissue, ensuring that the patch smoothly enters the rotator cuff tear location.
[0025] The sleeve assembly 300 is movably disposed at the distal end 102 along the first direction X. An opening 301 is provided at the end of the sleeve assembly 300 facing away from the proximal end 101. A second connector 531 is wound around a second rotating member 530 and connected to the sleeve assembly 300. The second rotating member 530 rotates to wind around the second connector 531, and the second connector 531 moves in a direction away from the distal end 102, pulling the sleeve assembly 300 to move synchronously in the same direction. After the sleeve assembly 300, the clamp arm 210, and the patch synchronously enter the rotator cuff tear position, the sleeve assembly 300 moves along the first direction X towards the proximal end 101, that is, it moves away from the body. During this process, the clamp arm 210 and the patch detach from the sleeve assembly 300 through the opening 301. At this time, the patch is no longer restrained by the sleeve assembly 300, and then the clamp arm 210 releases the patch.
[0026] The unfolding arm 410 is located inside the cannula assembly 300. The unfolding arm 410 is adjacent to the clamping arm 210. The patch is rolled around the outside of the unfolding arm 410 and is set in the cannula assembly 300 in a rolled form. When the cannula assembly 300 moves in the first direction X toward the proximal end 101, the unfolding arm 410 and the patch are separated from the cannula assembly 300 through the opening 301. After the clamping arm 210 releases the patch, because the patch material itself is relatively thin, the patch in the implantation state is rolled and squeezed into the cannula 310 of the cannula assembly 300 and brought into the body. After being separated from the cannula 310, the rolled state cannot unfold on its own in the tight gap in the body. The third connector 541 is rolled around the third rotating member 540 and connected to the unfolding arm 410. The third rotating member 540 rotates and rolls around the third connector 541 toward the direction away from the distal end 102 to pull the unfolding arm 410 to unfold. The unfolding arm 410 unfolds and lays the patch flat before subsequent surgical steps can be performed.
[0027] The implanter in this embodiment can achieve clamping, tube removal and flattening operations by the first rotating member 520 winding the first connecting member 521, the second rotating member 530 winding the second connecting member 531, and the third rotating member 540 winding the third connecting member 541. This simplifies the operation process, significantly shortens the operation time, reduces the complexity of the drive unit 500 components, saves costs, and improves the reliability of the implanter.
[0028] When preparing the patch material, the first connector 521 and the third connector 541 are in a non-tensioned state, and the clamping arm 210 is in a relaxed state to facilitate the placement of the patch on the clamping arm 210. The unfolding arm 410 is in a closed state to facilitate the wrapping of the patch around the unfolding arm 410, making the patch wrapping operation convenient. The surgeon can wrap the patch material without the aid of external tools or fixtures. After the patch is wrapped, the first rotating member 520 is rotated. The first rotating member 520 wraps around the first connector 521 and pulls the clamping arm 210 to clamp the patch, thereby fixing the patch to the distal end 102 of the implantation site 100.
[0029] like Figures 2 to 4 As shown, in some optional embodiments, the second rotating member 530 and the third rotating member 540 are arranged side by side along the second direction Y. The housing 510 is provided with a driving gear 550 and a transmission gear 560 that mesh with each other. The drive unit 500 also includes a first trigger 570, which meshes with the driving gear 550 to drive the driving gear 550 to rotate. The transmission gear 560 is located on the side of the driving gear 550 close to the second rotating member 530 and the third rotating member 540. The transmission gear 560 is movably arranged along the second direction Y so that the transmission gear 560 can switch between meshing with the second rotating member 530 and the third rotating member 540. The first direction X and the second direction Y intersect.
[0030] In these optional embodiments, the first trigger 570 meshes with the drive gear 550 to drive the drive gear 550 to rotate. The drive gear 550 can drive the second rotating member 530 and the third rotating member 540 to rotate via the transmission gear 560, thereby winding around the second connecting member 531 and the third connecting member 541. Optionally, the drive gear 550 includes a first ratchet 550a and a first gear 550b coaxially arranged. Each time the first trigger 570 is pressed, the first trigger 570 abuts against the first ratchet 550a, driving the first gear 550b to rotate synchronously. The first gear 550b meshes with the transmission gear 560, driving the transmission gear 560 to rotate. The transmission gear 560 is movably arranged along the second direction Y, and the second rotating member 530 and the third rotating member 540 are arranged side by side along the second direction Y, so that the transmission gear 560 can switch between engaging the second rotating member 530 and engaging the third rotating member 540.
[0031] like Figure 3 As shown, when the transmission gear 560 moves along the second direction Y to engage with the second rotating member 530, each time the first trigger 570 is pressed, the first trigger 570 abuts against the first ratchet 550a, driving the first gear 550b to rotate synchronously. The first gear 550b engages with the transmission gear 560, driving the transmission gear 560 to rotate. The transmission gear 560 drives the second rotating member 531 to rotate and wrap around the second connecting member 531. The second connecting member 531 pulls the sleeve assembly 300 to move in the direction away from the distal end 102.
[0032] like Figure 4 As shown, when the transmission gear 560 moves along the second direction Y to engage with the third rotating member 540, each time the first trigger 570 is pressed, the first trigger 570 abuts against the first ratchet 550a, driving the first gear 550b to rotate synchronously. The first gear 550b engages with the transmission gear 560, driving the transmission gear 560 to rotate. The transmission gear 560 drives the third rotating member 540 to rotate and wrap around the third connecting member 541. The third connecting member 541 pulls the unfolding arm 410 to unfold.
[0033] Optional, such as Figures 2 to 4 As shown, the second rotating member 530 includes a second gear shaft 530b and a second gear 530a for meshing with the transmission gear 560, and a second connecting member 531 is wound around the second gear shaft 530b. The second gear shaft 530b extends along the second direction Y, and the second gear 530a is sleeved on the second gear shaft 530b and can be rotated synchronously.
[0034] Optional, such as Figures 2 to 4As shown, the third rotating member 540 includes a third gear shaft 540b and a third gear 540a for meshing with the transmission gear 560. A third connecting member 541 is wound around the third gear shaft 540b of the third rotating member 540. The third gear shaft 540b of the third rotating member 540 extends along the second direction Y, and the third gear 540a is sleeved on the third gear shaft 540b and can be rotated synchronously. Optionally, the second gear shaft 530b and the third gear shaft 540b are collinear in axis, which helps to improve compactness.
[0035] Optional, such as Figure 2 As shown, the second rotating member 530 and the third rotating member 540 are located on the side of the drive gear 550 along the third direction Z, and the first trigger 570 is located on the side of the drive gear 550 away from the second rotating member 530 along the third direction Z. The implantation part 100 is arranged side by side with the second rotating member 530 and the third rotating member 540 along the first direction X, so that the second connecting member 531 and the third connecting member 541 can extend directly into the receiving cavity 103 of the implantation part 100 along the first direction X, and the rotating member and gear structure inside the housing 510 are arranged more compactly.
[0036] Optional, such as Figure 2 As shown, the first rotating member 520 is located on the side of the drive gear 550 away from the implantation part 100 along the first direction X.
[0037] Optional, such as Figure 2 As shown, a guide shaft 523 is also provided inside the housing 510. The guide shaft 523 is arranged side by side with the implantation part 100 along the first direction X. The guide shaft 523 is located on the side of the second rotating member 530 and the third rotating member 540 opposite to the implantation part 100 along the first direction X. The first connecting member 521 extends from the first rotating member 520 to the receiving cavity 103 of the implantation part 100 via the rotating shaft. The guide shaft 523 is used to guide the first connecting member 521 and reduce the mutual interference between the first connecting member 521 and the internal components of the housing 510.
[0038] like Figures 2 to 4As shown, in some optional embodiments, a first trigger 570 is located outside the housing 510 and extends into the housing 510. The first trigger 570 is used to drive the drive gear 550 to rotate in a first rotation direction, so as to drive the second rotating member 530 and the third rotating member 540 to rotate in the first rotation direction through the transmission gear 560. The second rotating member 530 rotates in the first rotation direction and wraps around the second connecting member 531 to drive the sleeve assembly 300 to move in the direction away from the distal end 102. The third rotating member 540 rotates in the first rotation direction and wraps around the third connecting member 541 to drive the unfolding arm 410 to unfold. The implant also includes a first anti-rotation member 551, which is located inside the housing 510. The first anti-rotation member 551 abuts against the drive gear 550 to limit the rotation of the drive gear 550 in the opposite direction of the first rotation direction.
[0039] In these optional embodiments, the first trigger 570 is located outside the housing 510 for easy hand-operated pressing. The first trigger 570 extends into the housing 510 to abut against the drive gear 550 as it rotates in the first rotation direction. The transmission gear 560, meshing with the drive gear 550, rotates in the opposite direction of the first rotation direction. The transmission gear 560 drives the second rotating member 530 and the third rotating member 540 to rotate in the first rotation direction. Optionally, when the first rotation direction is clockwise, the opposite direction of the first rotation direction is counterclockwise from the same viewing angle; when the first rotation direction is counterclockwise, the opposite direction of the first rotation direction is clockwise from the same viewing angle.
[0040] The implant also includes a first anti-rotation member 551, which is located within the housing 510. The first anti-rotation member 551 abuts against the drive gear 550 to limit the drive gear 550 from rotating in the opposite direction of the first rotation direction. When the drive gear 550 includes a first ratchet 550a, the first anti-rotation member 551 abuts against the first ratchet 550a to limit the drive gear 550 from rotating in the opposite direction of the first rotation direction. The first trigger 570 can only drive the drive gear 550 to rotate in the first rotation direction, thereby moving the cannula assembly 300 in the direction away from the distal end 102 and driving the unfolding arm 410 to unfold. It cannot rotate in the opposite direction of the first rotation direction, thus ensuring that the implant in this embodiment can only be used for one surgery, reducing the risk of cross-contamination that may occur when used by others in a second surgery.
[0041] Optional, such as Figure 1 and Figure 2 As shown, the implanter also includes a handle 590, which is located on the side of the first trigger 570 away from the implantation part 100 along the first direction X, so that the handle 590 can be held to press the first trigger 570. Pressing the first trigger 570 toward the handle 590 can drive the drive gear 550 to rotate in the first rotation direction.
[0042] like Figure 2 In some optional embodiments, a first elastic element 571 is provided inside the housing 510. The first elastic element 571 is connected to the first trigger 570 and is used to provide the first trigger 570 with a spring force to move in a direction away from the handle 590.
[0043] In these optional embodiments, after pressing the first trigger 570 toward the handle 590 drives the drive gear 550 to rotate in the first rotation direction, the first elastic member 571 provides a spring force to the first trigger 570 to move away from the handle 590, so that the first trigger 570 drives the drive gear 550 to rotate and then reset. Pressing the first trigger 570 multiple times causes the drive gear 550 to rotate multiple times, driving the second rotating member 530 and the third rotating member 540 to rotate. Optionally, the first elastic member 571 is a tension spring, which is connected to the side of the first trigger 570 away from the handle 590 to provide tension to the first trigger 570.
[0044] like Figure 2 In some optional embodiments, a first ratchet 573 is provided on the first trigger 570, the first ratchet 573 is movably connected to the first trigger 570, and a second elastic member 572 is also provided in the housing 510, the second elastic member 572 is used to abut the first ratchet 573 against the first ratchet 550a.
[0045] In these alternative embodiments, pressing the first trigger 570 toward the handle 590 causes the first ratchet 573 to move, the first ratchet 573 abuts against the first ratchet 550a and causes the first ratchet 550a to rotate in the first rotation direction.
[0046] like Figures 1 to 4 In some optional embodiments, the housing 510 has first mounting holes 511 on both sides along the second direction Y, and the transmission gear 560 has connecting rods 561 on both sides along the second direction Y. The two ends of the connecting rods 561 are respectively installed in the two first mounting holes 511, and the two ends of the connecting rods 561 are exposed through the first mounting holes 511. The connecting rods 561 are configured to move the transmission gear 560 along the second direction Y by pressing the connecting rods 561.
[0047] In these optional embodiments, the housing 510 has first mounting holes 511 on both sides along the second direction Y. The transmission gear 560 has connecting rod 561 ends on both sides along the second direction Y. The two ends of the connecting rod 561 are respectively installed in the two first mounting holes 511. The connecting rod 561 can protrude out of the housing 510 through the first mounting holes 511. The connecting rod 561 is connected to the transmission gear 560. One of the two ends of the connecting rod 561 protrudes out of the housing 510, and the other is flush with the outer wall of the housing 510. Pressing down along the second direction Y will actuate the two ends of the connecting rod 561 that protrude out of the housing 510. One of the components causes the transmission gear 560 to move synchronously along the second direction Y, enabling the transmission gear 560 to switch between engaging the second rotating component 530 and the third rotating component 540. At this time, one of the two ends of the connecting rod 561 is flush with the outer wall of the housing 510, while the other end of the connecting rod 561 protrudes outside the housing 510. Pressing the other end of the connecting rod 561 protruding outside the housing 510 along the second direction Y causes the transmission gear 560 to move synchronously along the second direction Y, enabling the transmission gear 560 to switch between engaging the third rotating component 540 and the second rotating component 530, thereby facilitating the operator's operation.
[0048] like Figure 1 , Figure 2 and Figure 6 As shown, in some alternative embodiments, the implanter further includes a cutting assembly comprising a blade 610 movably configured to cut at least one of the first connector 521, the second connector 531, and the third connector 541, located within the housing 510.
[0049] In these optional embodiments, the blade 610 is movably configured to cut at least one of the first connector 521, the second connector 531, and the third connector 541. Optionally, the blade 610 can be used to cut any one of the first connector 521, the second connector 531, and the third connector 541; or, the blade 610 can be used to cut any two of the first connector 521, the second connector 531, and the third connector 541; or, the blade 610 can be used to cut the first connector 521, the second connector 531, and the third connector 541. If any one of the first connector 521, the second connector 531, and the third connector 541 is cut off, it loses its functionality. After the patch implantation is completed, the implanter must be discarded, thereby reducing the problem of repeated use of the implanter.
[0050] One end of the first connector 521 is wound around the first rotating member 520. The first connector 521 extends along the first direction X to the other end, which is connected to the clamping arm 210. The first connector 521 is in a tensioned state. The tension of the first connector 521 on the clamping arm 210 causes the clamping arm 210 to clamp the material to be implanted 10. After the first connector 521 is cut by the blade 610, the tension of the first connector 521 on the clamping arm 210 disappears instantly, and the clamping force of the clamping arm 210 on the material to be implanted 10 disappears, thereby releasing the material to be implanted 10.
[0051] One end of the second connector 531 is wound around the second rotating member 530. The second connector 531 extends along the first direction X to the other end and is connected to the cannula assembly 300. After the second connector 531 pulls the cannula assembly 300 away from the material to be implanted 10, the second connector 531 is cut by the blade 610 and loses its functionality. After the patch implantation is completed, the implanter can only be scrapped, thereby reducing the problem of repeated use of the implanter.
[0052] One end of the third connector 541 is wound around the third rotating member 540. The third connector 541 extends along the first direction X to the other end, which is connected to the unfolding arm 410. When the third connector 541 pulls the unfolding arm 410 to unfold, the third connector 541 is in a tensioned state. The pulling force of the third connector 541 on the unfolding arm 410 keeps the unfolding arm 410 in an unfolded state, making it difficult for the unfolding arm 410 to exit from the incision. After the third connector 541 is cut by the blade 610, the pulling force of the third connector 541 on the unfolding arm 410 disappears instantly. During the process of exiting the human body, the unfolding arm 410 is squeezed into a closed state by the human tissue, so that the implant can be exited.
[0053] like Figure 1 and Figure 2 As shown, in some optional embodiments, the housing 510 has a first groove 512 extending along the third direction Z. The cutting assembly includes a cutting button 620 located outside the housing 510. The cutting button 620 is movably mounted in the first groove 512 along the third direction Z. The cutting button 620 is connected to the blade 610 through the first groove 512. The first connector 521, the second connector 531 and the third connector 541 are located on the same side of the blade 610 along the third direction Z. The first direction X and the third direction Z intersect.
[0054] In these optional embodiments, the cutting button 620 is movably mounted in the first slide groove 512 along the third direction Z. The first slide groove 512 penetrates the side wall of the housing 510 along the second direction Y. The cutting button 620 is connected to the blade 610 located inside the housing 510 through the first slide groove 512. The movability of the cutting button 620 along the third direction Z enables the blade 610 to move synchronously along the third direction Z. The first connector 521, the second connector 531, and the third connector 541 are located on the same side of the blade 610 along the third direction Z, and the cutting edge of the blade 610 faces the first connector 521, the second connector 531, and the third connector. On one side of 541, the cutting button 620 moves the blade 610 along the third direction Z until the blade cuts at least one of the first connector 521, the second connector 531 and the third connector 541. The implanter in this embodiment is easy to operate. The blade 610 cuts at least one of the first connector 521, the second connector 531 and the third connector 541. Any one of the first connector 521, the second connector 531 and the third connector 541 is cut off and loses its functionality. After the patch is implanted, the implanter can only be disposed of according to the rules for disposable surgical instruments, thereby reducing the risk of the implanter being reused in other people's surgeries.
[0055] Optionally, the first direction X, the second direction Y, and the third direction Z intersect each other.
[0056] Optionally, the first direction X, the second direction Y, and the third direction Z are mutually perpendicular.
[0057] like Figure 2 and Figure 5 As shown, in some optional embodiments, the implantation part 100 is provided with a receiving cavity 103, which penetrates the implantation part 100 along a first direction X. The proximal end 101 of the implantation part 100 extends into the housing 510. The receiving cavity 103 communicates with the housing 510. The first connector 521 is connected to the clamping arm 210 through the receiving cavity 103 from the proximal end 101. The third connector 541 is connected to the unfolding arm 410 through the receiving cavity 103 from the proximal end 101. The second connector 531 is located outside the implantation part 100 and extends along the outer wall of the implantation part 100 from the proximal end 101 toward the distal end 102 and is connected to the cannula assembly 300.
[0058] In these optional embodiments, the implantation part 100 is a tubular structure, and the interior of the implantation part 100 is a receiving cavity 103. The proximal end 101 of the implantation part 100 is located inside the housing 510. The receiving cavity 103 extends through the distal end 102 and the proximal end 101 of the implantation part 100 along the first direction X, so that the receiving cavity 103 communicates with the interior of the housing 510. The first connector 521 extends from the proximal end 101 through the receiving cavity 103 along the first direction X to connect with the clamping arm 210 located at the distal end 102. The third connector 541 extends from the proximal end 101 through the receiving cavity 103 along the first direction X to connect with the unfolding arm 410 located at the distal end 102. The receiving cavity 103 is used to provide a guide channel for the first connector 521 and the third connector 541. The first connector 521 and the third connector 541, located within the receiving cavity 103, reduce interference from human tissue during their movement and minimize damage to human tissue. The cannula assembly 300 is fitted onto the outside of the implantation portion 100. The second connector 531, located outside the implantation portion 100, extends along the outer wall of the implantation portion 100 from the proximal end 101 towards the distal end 102 in the first direction X, and connects to the cannula assembly 300 for pulling the cannula assembly 300.
[0059] like Figure 2 As shown, in some optional embodiments, the cutting surface formed by the blade 610 moving along a third direction Z is disposed adjacent to the proximal end 101 of the implantation portion 100 along a first direction X.
[0060] In these optional embodiments, the first connector 521, the second connector 531, and the third connector 541 all extend from the proximal end 101 toward the distal end 102. The cutting surface formed by the blade 610 moving along the third direction Z is adjacent to the proximal end 101 of the implantation part 100 along the first direction X. Optionally, the distance between the cutting surface formed by the blade 610 moving along the third direction Z and the proximal end 101 of the implantation part 100 along the first direction X is greater than 0 and less than 2 cm. The first connector 521 and the third connector 541 enter the receiving cavity 103 through the proximal end 101. The proximal end 101 of the implantation part 100 forms a cannula constraint on the first connector 521 and the third connector 541 at the cannula position perpendicular to the first direction X, thereby improving the success rate of the blade 610 cutting the first connector 521 and the third connector 541. Optionally, the proximal end 101 of the implantation portion 100 is connected to the outer wall of the housing 510 and communicates with the inside of the housing 510, or the proximal end 101 of the implantation portion 100 extends into the inside of the housing 510, thereby reducing the distance between the proximal end 101 of the implantation portion 100 and the blade 610 along the first direction X.
[0061] Optionally, the first connector 521, the second connector 531, and the third connector 541 are all configured with a pull rope structure so that when the drive gear rotates, the gear shaft can wrap around the pull rope to generate an effective pulling effect on the connector, while the feasible blade 610 can effectively cut the first connector 521, the second connector 531, and the third connector 541.
[0062] The materials of the first connector 521, the second connector 531, and the third connector 541 may include non-metallic materials, such as aramid, ultra-high molecular weight polyethylene, or glass fiber reinforced nylon. These three types of non-metallic cables have good structural strength and a high flexibility coefficient.
[0063] like Figure 1 and Figure 2 As shown, in some optional embodiments, the implanter further includes a second trigger 580 extending from the outside of the housing 510 to the inside of the housing 510. The second trigger 580 is used to drive the first rotating member 520 to rotate in a second rotation direction. The first rotating member 520 rotates in the second rotation direction to wrap around the first connecting member 521 to drive the clamping arm 210 to clamp the material 10 to be implanted.
[0064] In these optional embodiments, the second trigger 580 is located outside the housing 510, facilitating pressing of the second trigger 580 from outside the housing 510 to inside the housing 510. The second trigger 580 abuts against the first rotating member 520, and pressing the second trigger 580 drives the first rotating member 520 to rotate in a second rotation direction. Optionally, the first rotating member 520 includes a synchronously rotating second ratchet 520a and a rotating shaft, with the second ratchet 520a sleeved on... On the shaft of the first rotating member 520, the first connecting member 521 is wound around the shaft of the first rotating member 520. Each time the second trigger 580 is pressed, the second trigger 580 abuts against the second ratchet 520a, driving the second ratchet 520a to rotate and causing the shaft of the first rotating member 520 to rotate. The shaft of the first rotating member 520 moves around the first connecting member 521 toward the direction away from the distal end 102. The first connecting member 521 provides a clamping force to the clamping arm 210 for the material 10 to be implanted.
[0065] Optionally, the first rotation direction and the second rotation direction can be the same. When the first rotation direction is clockwise, the second rotation direction is clockwise from the same viewing angle; when the first rotation direction is counterclockwise, the second rotation direction is counterclockwise from the same viewing angle. Alternatively, the first rotation direction and the second rotation direction can be opposite. When the first rotation direction is clockwise, the second rotation direction is counterclockwise from the same viewing angle; when the first rotation direction is counterclockwise, the second rotation direction is clockwise from the same viewing angle.
[0066] like Figure 2 As shown, in some optional embodiments, the implanter further includes a second anti-rotation member 522, which is located within the housing 510. The second anti-rotation member 522 is movably configured and includes an anti-rotation spring 522a. The second anti-rotation member 522 is moved such that the anti-rotation spring 522a abuts against the first rotating member 520 to limit the first rotating member 520 from rotating in the opposite direction of the second rotation direction. The second anti-rotation member 522 is moved such that the anti-rotation spring 522a is spaced apart from the first rotating member 520, and the first rotating member 520 can rotate in the opposite direction of the second rotation direction to release the implantable material 10.
[0067] In these optional embodiments, the second anti-rotation member 522 is used to limit the first rotating member 520 from rotating in the opposite direction of the second rotation direction, thereby ensuring that the clamping arm 210 holds the material to be implanted 10 and reducing the risk that the clamping arm 210 will release the material to be implanted before the implanter is inserted into the damaged site. The second anti-rotation member 522 is movably configured such that the anti-rotation spring 522a abuts against the first rotating member 520 to limit the first rotating member 520 from rotating in the opposite direction of the second rotation direction. The second anti-rotation member 522 is also moved such that the anti-rotation spring 522a is spaced apart from the first rotating member 520, allowing the first rotating member 520 to rotate in the opposite direction of the second rotation direction, thereby enabling the first connecting member 521 to move in the direction closer to the distal end 102, allowing the clamping arm 210 to release the material to be implanted 10. When it is necessary to replace the implantable material 10, or when the winding state of the implantable material 10 at the distal end 102 is poor, the second anti-rotation member 522 is moved until the anti-rotation spring 522a is spaced apart from the first rotating member 520, allowing the first rotating member 520 to rotate in the opposite direction of the second rotation direction to release the implantable material 10. When the clamping arm 210 needs to clamp the implantable material 10 again, the second anti-rotation member 522 is moved until the anti-rotation spring 522a abuts against the first rotating member 520, and the second trigger 580 is pressed to drive the first rotating member 520 to rotate in the second direction Y, and the clamping arm 210 clamps the implantable material 10.
[0068] like Figure 2As shown, in some optional embodiments, the second trigger 580 is provided with a second ratchet 581, which is movably connected to the second trigger 580. The second ratchet 581 extends toward the first rotating member 520, and the end of the second ratchet 581 near the first rotating member 520 has a latch 582. The second anti-rotation member 522 further includes a release plate 522b, which abuts against the latch 582 to disengage the second ratchet 581 of the second trigger 580 from the abutment of the first rotating member 520. The rotating spring 522a is synchronously movable so that the first rotating member 520 can switch between a first state and a second state. In the first state, both the anti-rotation spring 522a and the second ratchet 581 abut against the first rotating member 520, and the first rotating member 520 can rotate in the second rotation direction. In the second state, the anti-rotation spring 522a is spaced apart from the first rotating member 520, and the release plate 522b moves the lever 582 until the second ratchet 581 is spaced apart from the first rotating member 520, and the first rotating member 520 can rotate in the opposite direction of the second rotation direction.
[0069] In these optional embodiments, the end of the second ratchet 581 near the first rotating member 520 contacts the second ratchet 520a of the first rotating member 520, for driving the first rotating member 520 to rotate. The end of the second ratchet 581 near the second ratchet 520a of the first rotating member 520 has a latch 582, which allows the second ratchet 581 and the second ratchet 520a of the first rotating member 520 to be spaced apart, ensuring that the first rotating member 520 is not disturbed by the second ratchet 581 when rotating in the opposite direction of the second rotation direction. The second anti-rotation member 522 also includes a release plate 522b, which abuts against the latch 582 to disengage the second ratchet 581 from the abutment of the second ratchet 520a of the first rotating member 520. The release plate 522b and the anti-rotation spring 522a are synchronously movable. In the first state, both the anti-rotation spring 522a and the second ratchet 581 abut against the first rotating member 520, and the second trigger 580 can drive the first rotating member 520 to rotate in the second rotation direction. The anti-rotation spring 522a can restrict the first rotating member 520 from reversing. In the second state, both the anti-rotation spring 522a and the second ratchet 581 are spaced apart from the second ratchet 520a of the first rotating member 520, and the first rotating member 520 can rotate in the opposite direction of the second rotation direction. Optionally, the latches 582 are located on both sides of the second ratchet 581 along the second direction Y and extend along the second direction Y, and the release plate 522b is in contact with the two latches 582.
[0070] Optional, such as Figure 2 As shown, the release plate 522b and the anti-rotation spring 522a are integrated into one piece.
[0071] Optional, such as Figure 2As shown, the second anti-rotation member 522 is located on the side of the first rotating member 520 away from the implantation part 100 along the first direction X. The second anti-rotation member 522 is movable along the third direction Z. The release plate 522b is inclined in the direction away from the first rotating member 520, so that when the release plate 522b moves along the third direction Z, the release pin 582 is movable in the direction close to or away from the first rotating member 520.
[0072] like Figure 1 and Figure 2 As shown, in some optional embodiments, the second anti-rotation member 522 further includes an anti-rotation button 522c, which is movably disposed outside the housing 510 in the third direction Z. The anti-rotation button 522c is connected to the release plate 522b and the anti-rotation spring 522a located inside the housing 510.
[0073] In these alternative embodiments, the release plate 522b and the anti-rotation spring 522a are moved along the third direction Z by sliding the anti-rotation button 522c so that the first rotating member 520 can switch between a first state and a second state.
[0074] like Figure 2 As shown, in some optional embodiments, the second trigger 580 is rotatably connected to the housing 510, the second ratchet 581 extends toward the second ratchet 520a, and a third elastic member 583 is also provided in the housing 510, the third elastic member 583 being used to abut the second ratchet 581 against the second ratchet 520a.
[0075] In these optional embodiments, the third elastic member 583 provides a spring force to the second ratchet 581 toward the second ratchet 520a, so that the second ratchet 581 always abuts against the second ratchet 520a during operation. Pressing the second trigger 580 toward the second ratchet 520a moves the second ratchet 581, causing the second ratchet 581 to abut against the second ratchet 520a and rotate the second ratchet 520a in the second rotation direction. Optionally, the latch 582 is located at one end of the second ratchet 581 near the second ratchet 520a. During the movement of the release plate 522b away from the second trigger 580, the release plate 522b moves the latch 582 to make the second ratchet 581 and the second ratchet 520a spaced apart. During the movement of the release plate 522b toward the second trigger 580, the third elastic member 583 pulls the second ratchet 581 toward the second ratchet 520a until the second ratchet 581 contacts the second ratchet 520a.
[0076] Optional, such as Figure 2As shown, a first support rod 584 is provided on the second trigger 580, and a second support rod 585 is provided on the second ratchet 581. The second ratchet 581 is hinged to the second trigger 580. The second trigger 580 is rotatably connected to the housing 510 through a third rotating shaft 586. The third rotating shaft 586 is located between the first support rod 584 and the second ratchet 581. The first support rod 584 and the second support rod 585 are respectively located on both sides of the second ratchet 520a of the first rotating member 520 along the first direction X. A third elastic member 583 is connected between the first support rod 584 and the second support rod 585. The first support rod 584 is located on the side of the second support rod 585 away from the first rotating member 520 along the third direction Z. The third elastic member 583 is used to provide elastic force to the second support rod 585 in the direction of the first support rod 584. During the pressing process of the second trigger 580 extending outside the housing 510 toward the second ratchet 520a of the first rotating member 520, the first support rod 584 moves toward the second ratchet 520a away from the first rotating member 520. The second trigger 580 drives the second ratchet 581 to move the second support rod 585 away from the first support rod 584. The third elastic member 583 is stretched by the first support rod 584 and the second support rod 585. The direction of the elastic force of the third elastic member 583 is toward the first support rod 584. After the pressing pressure disappears, the third elastic member 583 pulls the first support rod 584 and the second support rod 585 closer to each other, so that the part of the second trigger 580 located outside the housing 510 moves toward the second ratchet 520a away from the first rotating member 520, thereby resetting the second trigger 580.
[0077] Optional, such as Figure 1 As shown, the housing 510 has a second groove 513 on the side opposite to the implantation part 100 along the first direction X. The second groove 513 extends along the third direction Z. The second trigger 580 extends from the outside of the housing 510 through the second groove 513 into the housing 510. The second trigger 580 is disposed through the second groove 513 and is movable within the second groove 513 along the third direction Z.
[0078] like Figure 5 As shown, in some optional embodiments, the distal end 102 of the implantation part 100 is provided with a first fixing plate 120, the clamping arm 210 is arranged side by side with the first fixing plate 120, the material to be implanted 10 is disposed between the first fixing plate 120 and the clamping arm 210, and the first rotating member 520 drives the clamping arm 210 to move closer to the first fixing plate 120 by winding the first connecting member 521.
[0079] like Figure 1 and Figure 7In some optional embodiments, the cannula assembly 300 includes a cannula 310 and a connecting tube 320 arranged along a first direction X. The cannula 310 and the connecting tube 320 are connected to each other. The cannula 310 is sleeved on the first fixing plate 120, and the connecting tube 320 is sleeved on the outside of the implantation part 100. The cannula 310 is detachably connected to the connecting tube 320, and an opening 301 is provided at one end of the cannula 310 facing away from the proximal end 101.
[0080] In these alternative embodiments, the patch is located inside a cannula 310, which, together with the patch, enters the body through a small incision. The cannula 310 ensures that the patch is isolated from the body tissue as it extends through the incision to the location of the rotator cuff tear.
[0081] The sleeve 310 is detachably connected to the connecting tube 320, and the sleeve 310 and the connecting tube 320 are interconnected. Before installing the sleeve 310, the patch is clamped between the clamping arm 210 and the first fixing plate 120. Then, the patch is inserted into the sleeve 310 from the distal end 102 towards the proximal end 101. The sleeve 310 is then connected to the connecting tube 320. Optionally, the sleeve 310 can be a disposable plastic tube. Since the sleeve 310 holds the patch and needs to enter the human body, for medical and hygiene reasons, a disposable plastic tube can be used, which can be replaced after each use. Furthermore, disposable plastic tubes are lighter and have lower manufacturing costs.
[0082] After the sleeve 310, clamp arm 210 and patch enter the rotator cuff tear position simultaneously, the sleeve 310 and connecting tube 320 move towards the proximal end 101 in the first direction X, and the clamp arm 210, the first fixing plate 120 and the patch disengage from the sleeve 310 through the opening 301.
[0083] like Figure 1 and Figure 8 As shown, in some optional embodiments, the sleeve 310 is provided with a buttonhole 311 on the side facing the proximal end 101, and the connecting tube 320 is provided with a snap fastener 331 on the side facing away from the proximal end 101, and the snap fastener 331 is engaged with the buttonhole 311.
[0084] In these optional embodiments, the sleeve 310 has a notch 311 on the side facing the proximal end 101, and the connecting tube 320 has a snap fastener 331 on the side facing away from the proximal end 101. When the sleeve 310 and the connecting tube 320 are installed together, the connection can be completed simply by inserting the snap fastener 331 into the notch 311. The connection process is simple and easy to operate. The number and position of the snap fasteners 331 are adapted to the position and number of the notch 311.
[0085] Optional, such as Figure 9As shown, the sidewall of the cannula 310 is provided with multiple spaced water passages 312, which improves the problem of the patch being vacuum-adhered to the inner sidewall of the cannula 310. Furthermore, during arthroscopic surgery, fluid is continuously injected into the surgical site to support the human tissue and create a surgical space. With multiple water passages 312 on the sidewall of the cannula 310, the fluid can permeate the patch through the water passages 312, facilitating the patch's detachment and deployment from the cannula 310.
[0086] like Figures 8 to 16 As shown, in some optional embodiments, the connecting tube 320 includes a connecting tube body 330 and a locking tube 340. The locking tube 340 is disposed inside the connecting tube body 330. The second connector 531 is connected to the end of the locking tube 340 away from the distal end 102. The snap fastener 331 is disposed at the end of the connecting tube body 330 facing the distal end 102. The locking tube 340 includes a flange portion 341 disposed on the side facing the distal end 102. The outer diameter of the flange portion 341 is larger than the inner diameter of the snap fastener 331. The flange portion 341 is used to press against the snap fastener 331 to fix the snap fastener 331 to the buttonhole 311.
[0087] In these optional embodiments, both the connecting tube body 330 and the locking tube 340 can move along the first direction X. The snap fastener 331 is disposed at one end of the connecting tube body 330 facing the distal end 102. At least a portion of the sleeve 310 is located outside the connecting tube body 330, that is, the buckle eye 311 is located outside the snap fastener 331. The locking tube 340 has a flange portion 341 disposed on the side facing the distal end 102. The locking tube 340 is disposed inside the connecting tube body 330, that is, the flange portion 341 is located inside the snap fastener 331.
[0088] The locking tube 340 moves along the first direction X relative to the connecting tube body 330 towards the proximal end 101 until the flange portion 341 abuts against the inner side of the snap fastener 331. Since the outer diameter of the flange portion 341 is larger than the inner diameter of the snap fastener 331, the flange portion 341 presses against the snap fastener 331, causing the snap fastener 331 to undergo elastic deformation. The flange portion 341 firmly presses the snap fastener 331 into the eyelet 311, reducing the possibility of loosening between the connecting tube body 330 and the sleeve 310, and preventing the sleeve 310 from falling off. Optionally, the flange portion 341 can be a frustum-shaped structure, with the diameter of the flange portion 341 gradually increasing towards the distal end 102, which facilitates pressing against the snap fastener 331 to gradually increase the diameter of the snap fastener 331.
[0089] Optionally, the end of the sleeve assembly 300 facing the proximal end 101 is provided with a connection hole 342, and the second connector 531 is connected to the connection hole 342. Optionally, such as... Figure 12As shown, the connecting hole 342 is located at the end of the locking tube 340 away from the distal end 102. The second connector 531 passes through the connecting hole 342. The second connector 531 moves towards the proximal end 101 by pulling the locking tube 340. The flange portion 341 of the locking tube 340 drives the connecting tube 320 and the sleeve 310 to move towards the proximal end 101.
[0090] like Figure 5 , Figures 17 to 24 As shown, in some optional embodiments, the clamping part 200 further includes a guide part 240 and a fixing shaft 250. The implantation part 100 is provided with a clearance hole 290 located between the first connector 521 and the clamping arm 210. The guide part 240 is located in the clearance hole 290. One end of the guide part 240 is connected to the end of the clamping arm 210 facing the proximal end 101, and the other end of the guide part 240 is connected to the first connector 521. The guide part 240 also includes a guide groove 241 extending along the extension direction of the guide part 240. The outer wall of the housing 510 is provided with two bent edges 113 on both sides of the clearance hole 290. The fixing shaft 250 is connected between the two bent edges 113 and passes through the guide groove 241. The guide part 240 is used to move the clamping arm 210 along the extension direction of the guide groove 241 to approach the first fixing plate 120 and cooperate with the first fixing plate 120 to clamp the material to be implanted 10.
[0091] In these alternative embodiments, the first connector 521 is connected to the clamping arm 210 via the guide portion 240, the first connector 521 moves in the direction away from the distal end 102 along the first direction X, and the first connector 521 drives the clamping arm 210 to approach the first fixing plate 120 via the guide portion 240.
[0092] Since the first connector 521 is located in the receiving cavity 103 and the clamping arm 210 is located outside the receiving cavity 103, the clearance hole 290 connects the inside of the receiving cavity 103 with the outside of the implantation part 100. The guide part 240 connects the first connector 521 located inside the receiving cavity 103 and the clamping arm 210 located outside the implantation part 100 through the clearance hole 290. The extension direction of the guide part 240 intersects with the first direction X.
[0093] like Figure 18As shown, the guide portion 240 also includes a guide groove 241 extending along the extension direction of the guide portion 240. The fixing shaft 250 is fixed on the bent edges 113 on both sides of the clearance hole 290. The fixing shaft 250 passes through the guide groove 241. By setting the fixing shaft 250, the movement direction of the guide portion 240 moves along the extension direction of the guide groove 241. When the first connector 521 moves toward the direction away from the distal end 102, the first connector 521 drives the clamping arm 210 to move through the guide portion 240. Since the guide portion 240 moves along the extension direction of the guide groove 241, that is, the guide portion 240 moves along the extension direction close to the first connector 521, thereby causing the clamping arm 210 to move along the extension direction close to the first connector 521, that is, the clamping arm 210 moves along the direction close to the first fixing plate 120 to clamp the patch.
[0094] Optional, such as Figure 5 , Figures 25 to 28 As shown, the unfolding arm 410 is located on the side of the first fixation plate 120 away from the clamping arm 210 and inside the cannula assembly 300. The unfolding arm 410 and the clamping arm 210 are opposite each other, that is, the unfolding arm 410 and the patch are opposite each other. The patch is rolled up inside the cannula assembly 300. When the cannula assembly 300 moves along the first direction X toward the proximal end 101, the unfolding arm 410, the clamping arm 210 and the patch are separated from the cannula assembly 300 through the opening 301. After the clamping arm 210 moves away from the first fixation plate 120 to release the patch, since the patch material itself is relatively thin, the patch in the implantation state is rolled up and put into the cannula 310 and brought into the body. After the patch is removed from the cannula 310, the rolled-up state of the patch cannot unfold itself in the tight intermuscular space. Therefore, the unfolding arm 410 is set at the relative position of the patch. Part of the unfolding arm 410 moves along the second direction Y to unfold the patch. The subsequent surgical steps can only be performed after the patch is laid flat. Optionally, the unfolding arm 410 can be rotated about one end of the unfolding arm 410 as an axis to unfold the patch.
[0095] like Figure 5 and Figure 29 As shown, in some optional embodiments, the implantation unit 100 further includes a second fixing plate 130 connected to the distal end 102 of the housing 510. The second fixing plate 130 is located on the side of the unfolding arm 410 away from the first fixing plate 120, and both the second fixing plate 130 and the first fixing plate 120 are located inside the sleeve 310.
[0096] In these alternative embodiments, the first fixing plate 120 and the second fixing plate 130 are located on both sides of the deployable arm 410, thereby providing protection for the deployable arm 410.
[0097] like Figures 30 to 36As shown, in some optional embodiments, the deployable arm 410 includes two first deployable arms 411 disposed opposite to each other. The first deployable arms 411 are located between the first fixed plate 120 and the second fixed plate 130. The two first deployable arms 411 are rotatably connected to the first fixed plate 120 and the second fixed plate 130 on one side of the proximal end 101. The two first deployable arms 411 are connected to a third connector 541, which is used to drive the first deployable arms 411 to rotate.
[0098] In these alternative embodiments, the first deployable arm 411 is rotatably connected between the first fixed plate 120 and the second fixed plate 130 via a first pivot 140. The deployable arm 410 includes two opposing first deployable arms 411, which are rotatably connected between the first fixed plate 120 and the second fixed plate 130 on the side facing the proximal end 101. The first unfolding arm 411 includes a closed state and an unfolded state. In the closed state, the two first unfolding arms 411 extend along the first direction X and are parallel to each other. When the unfolding arm 410 switches from the closed state to the unfolded state, the third connector 541 moves away from the distal end 102 along the first direction X. The third connector 541 pulls the first unfolding arm 411 to move towards the proximal end 101 along the first direction X. The first unfolding arm 411 rotates outward about the connection point with the first fixing plate 120. The two first unfolding arms 411 open. At this time, it is in the unfolded state. During the rotation of the first unfolding arm 411, it pushes the patch to unfold the patch, which facilitates the subsequent suturing of the patch with the torn tendon.
[0099] like Figures 30 to 36 As shown, in some optional embodiments, the deployable arm 410 further includes two second deployable arms 412 disposed opposite to each other. The two second deployable arms 412 are offset from the two first deployable arms 411 along the first direction X and are located between the first fixing plate 120 and the second fixing plate 130. The two second deployable arms 412 are located on the side of the first deployable arm 411 away from the proximal end 101. The second deployable arms 412 are rotatably connected to the first fixing plate 120 and the second fixing plate 130. The two second deployable arms 412 are rotatably connected to the third connector 541, which is used to drive the second deployable arms 412 to rotate.
[0100] In these optional embodiments, the second unfolding arm 412 is rotatably connected between the first fixing plate 120 and the second fixing plate 130 via the second rotating shaft 150. The second unfolding arm 412 is configured in the same way as the first unfolding arm 411, and includes a closed state and an unfolded state. The second unfolding arm 412 has the beneficial effects of the first unfolding arm 411 described above, which will not be repeated here. The two second unfolding arms 412 are offset from the two first unfolding arms 411 along the first direction X, meaning that when the two second unfolding arms 412 and the two first unfolding arms 411 are in the unfolded state, the contact positions between the first unfolding arms 411 and the patch are different. Optionally, the patch can be rectangular, and the first unfolding arms 411 and the second unfolding arms 412 respectively abut against the four corners of the rectangular patch. This arrangement makes the patch more extended, which is helpful for subsequent patch sewing steps.
[0101] Optional, such as Figures 33 to 35 As shown, a pull bar 542 is provided between the third connector 541 and the unfolding arm 410, and the pull bar 542 connects the two first unfolding arms 411, the two second unfolding arms 412 and the third connector 541. One end of the pull bar 542 facing the proximal end 101 is connected to the third connector 541. The pull bar 542 is divided into two sections on both sides of the unfolding arm 410 along the second direction Y. One section of the pull bar 542 connects the first unfolding arm 411 and the second unfolding arm 412 located on one side of the second direction, and the other section of the pull bar 542 connects the first unfolding arm 411 and the second unfolding arm 412 located on the other side of the second direction. The pull bar 542 is rotatably connected to the two first unfolding arms 411 on the proximal end 101 side, and the pull bar 542 is also rotatably connected to the two second unfolding arms 412 on the proximal end 101 side. When the third connector 541 moves in the direction away from the distal end 102, it pulls the pull bar 542 to move in the direction of the proximal end 101. The pull bar 542 pulls the first unfolding arm 411 and the second unfolding arm 412 to unfold in the second direction Y to flatten the patch.
