Description

Technical Field

[0001] This invention relates to the field of rotator cuff repair, specifically to an anchor implantation guide device for arthroscopic rotator cuff repair. Background Technology

[0002] Rotator cuff repair anchors are core medical devices commonly used in rotator cuff injury repair surgery. They are primarily used to fix the damaged rotator cuff tissue to the bone surface. Through the threaded fixation of the anchors, the rotator cuff tissue is repositioned and healed, ensuring a successful repair. Arthroscopic rotator cuff repair anchor implantation guides are auxiliary instruments used in conjunction with the anchors. Under the minimally invasive surgical field of arthroscopy, they provide precise guidance, positioning, and limitation for anchor implantation, ensuring that the angle and depth of anchor implantation meet surgical requirements. This assists medical staff in performing delicate implantation procedures and reduces surgical trauma.

[0003] However, in existing technologies, when using anchor implantation guide devices for arthroscopic rotator cuff repair, the device must first be positioned and fixed at the patient's shoulder joint. Then, the guide structure must be manually adjusted according to the anchor specifications. The guide structure is difficult to flexibly adapt to anchors of different specifications, and there is no convenient guide structure at the guide inlet. The anchor is prone to jamming when being inserted, making it difficult to quickly complete the anchor insertion and depth positioning. This increases the difficulty of operation for medical staff, prolongs the operation time, and is prone to deviation in anchor implantation depth, affecting the accuracy of anchor implantation, thereby reducing the efficiency of the operation and the quality of rotator cuff repair. Summary of the Invention

The depth limiting assembly includes a limiting ring, the inner wall of which is slidably connected to the outer wall of the guide tube, an adjusting bolt threadedly connected to the inner wall of the limiting ring, and a limiting rod fixedly connected to the outer wall of the limiting ring.

[0011] Preferably, the positioning assembly includes a fixing plate, the inner wall of which is fixedly connected to the outer wall of the third rotating rod, a limiting post rotatably connected to the inner wall of the fixing plate, a first gear fixedly connected to the outer wall of the limiting post, a first rack meshing with the tooth end of the first gear, a limiting disk fixedly connected to the top end of the first rack, a motor fixedly connected to the top end of the limiting disk, the output end of the motor rotatably connected to the inner wall of the limiting disk and fixedly connected to a rotating post, the outer wall of the rotating post rotatably connected to the inner wall of the limiting disk, and a first slider fixedly connected to the bottom end of the first rack, the outer wall of the first slider slidably connected to the inner wall of the fixing plate.

[0015] Working principle: When different implantation angles of the anchor need to be adapted, hold the disc and rotate it. The disc drives the second rotating rod to rotate, and the second rotating rod drives the second rotating ball to rotate on the inner wall of the limiting box. This, in turn, drives the third rotating rod to rotate synchronously. The third rotating rod drives the guide component and the locking component to adjust the angle together. When the angle is adjusted to meet the surgical requirements, rotate the second bolt. The second bolt rotates on the inner wall of the limiting box and pushes the limiting ball to move, so that the limiting ball presses against the second rotating ball, fixing the second rotating ball, and thus fixing the angle of the guide component.

[0016] When the device needs to be positioned, the first rotating rod is rotated, which drives the first rotating ball to rotate on the inner wall of the first limiting block, thereby causing the adsorption plate to adjust its angle so that the adsorption plate can accurately fit the surgical site of the patient's shoulder joint. At the same time, the first bolt is rotated, which rotates on the inner wall of the fixing block and pushes the rubber top block to move, so that the rubber top block is pressed against the patient's skin, thus achieving double fixation of the device in conjunction with the adsorption plate.

[0017] When the anchor needs to be inserted, the guide sleeve is positioned on the outside of the guide tube according to the anchor length specification. The side wall of the guide sleeve is equipped with a positioning pin, and the side wall of the guide tube is equipped with multiple positioning holes evenly distributed along its length. The positioning pin is inserted into the guide sleeve and the corresponding positioning hole to fix the guide sleeve to fit the current anchor length. The top of the guide tube is equipped with a guide funnel, the inner diameter of which gradually decreases from top to bottom, making it easy for the anchor to be quickly placed into the guide channel. Then, the anchor is placed into the guide channel of the guide tube through the guide funnel. At the same time, the sliding limiting ring is positioned on the outer wall of the guide tube to set the anchor insertion depth. The adjusting bolt is rotated to fix the limiting ring. When the anchor is inserted, the limiting ring forms a physical barrier to ensure that the anchor insertion depth meets the requirements.

[0018] When the anchor needs to be locked in place, the motor is started. The rotation of the motor drives the rotating column to rotate, causing the rotating column to rotate on the inner wall of the limiting plate. The rotating column drives the second gear to rotate, and the second gear meshes with the gear ring and the second rack at the same time, causing the four second racks to move synchronously, thereby causing the four clamps to move closer to each other, so as to achieve a stable clamping and locking of the anchor.

[0019] When it is necessary to observe the depth position of the anchor, the rotation of the limiting post will drive the third gear to rotate synchronously. The third gear meshes with the third rack, causing the third rack to move left and right. The third rack drives the depth scale to move, and the depth scale slides on the inner wall of the limiting cylinder. By observing the scale of the depth scale, medical staff can keep track of the adjustment height of the positioning component and the relative position of the anchor in real time.

[0020] This invention provides an anchor implantation guide device for arthroscopic rotator cuff repair. It has the following beneficial effects: 1. This invention uses a sliding guide sleeve, with positioning pins on the side wall of the guide sleeve, to fix the guide sleeve according to the length specifications of the anchor pins. The inner diameter of the guide funnel at the top of the guide tube gradually decreases from top to bottom, which facilitates the rapid insertion of the anchor pins into the guide channel. After the anchor pins are inserted into the guide channel through the guide funnel, the sliding limiting ring is used to set the implantation depth and is fixed by adjusting the bolts. This invention can flexibly adapt to different anchor pins, quickly complete the insertion and depth positioning of the anchor pins, avoid implantation depth deviation and insertion jamming, reduce the difficulty of operation, save surgical time, ensure accurate anchor pin insertion, and improve surgical efficiency and rotator cuff repair quality.

[0021] 2. This invention uses a rotating disc to rotate a second rotating rod, which in turn rotates a third rotating rod synchronously. This allows for synchronized angle adjustment of the guide assembly and the locking assembly. After the angle adjustment is complete, rotating the second bolt pushes the limiting ball against the second rotating ball to fix the angle. This effectively prevents the anchor implantation angle from shifting, reduces the difficulty of operation for medical staff, saves surgical adjustment time, adapts to the needs of rotator cuff injury repair in different locations, and ensures stable rotator cuff repair results.

[0022] 3. This invention rotates the first rotating rod, causing the first rotating ball to rotate on the inner wall of the first limiting block, which in turn causes the suction cup to adjust its angle, allowing the suction cup to precisely fit the surgical site of the patient's shoulder joint. At the same time, rotating the first bolt causes it to rotate on the inner wall of the fixing block and pushes the rubber top block to move, allowing the rubber top block to press tightly against the patient's skin. Together with the suction cup, the device achieves double fixation, effectively preventing device displacement during surgery, reducing the difficulty of positioning operations for medical staff, saving positioning time, and ensuring the smooth progress of rotator cuff repair surgery.

[0023] 4. This invention starts the motor, which drives the rotating column to rotate on the inner wall of the limiting plate. The rotating column drives the second gear to rotate. The second gear meshes with the gear ring and the four second racks at the same time, causing the four second racks to move synchronously. This causes the four clamps to move closer to each other, limiting the anchor nail and preventing the anchor nail from shifting or tilting due to uneven force. This ensures that the anchor nail is firmly locked in place, effectively preventing the anchor nail from shifting during the implantation process, and is compatible with anchor nails of different specifications.

[0024] 5. This invention uses the rotation of the limiting post to drive the third gear to rotate synchronously. The third gear meshes with the third rack, causing the third rack to move left and right, which in turn causes the depth scale to slide on the inner wall of the limiting cylinder. The depth scale slides smoothly on the inner wall of the limiting cylinder. By observing the scale of the depth scale, medical staff can keep track of the adjustment height of the positioning component and the relative position of the anchor in real time, avoiding deviations caused by medical staff relying on experience. This effectively prevents incorrect anchor implantation depth and positioning deviation, reduces the difficulty of operation for medical staff, and saves observation and adjustment time.

[0028] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides an anchor implantation guide device for rotator cuff repair under shoulder arthroscopy, including a positioning seat 1, a positioning component 2 and an adjustment component 3 on the outer wall of the positioning seat 1, a guide component 4 connected to the outer wall of the adjustment component 3, a depth limiting component 5 on the outer wall of the guide component 4, a locking component 6 on the inner wall of the positioning seat 1, an observation component 7 on the outer wall of the locking component 6, a flexible anti-slip pad 8 fixedly connected to the outer wall of the positioning seat 1, and a buffer component 9 on the inner wall of the positioning seat 1. Specifically, the inner wall of the positioning seat 1 is equipped with a locking component 6 and a buffer component 9, and the outer wall is fixed with a flexible anti-slip pad 8, which can conform to the patient's shoulder joint area to achieve initial fixation of the device at the surgical site, prevent the device from sliding during the operation, and adapt to the physiological curvature of the shoulder joint. The flexible anti-slip pad 8 is made of medical-grade silicone material, which can conform to the physiological contour of the patient's shoulder joint, reduce the pressure of the device on the patient's skin and soft tissue, avoid skin damage or patient discomfort caused by prolonged pressure during the operation, improve the patient's tolerance during the operation, and the surface has anti-slip properties to increase the friction between the device and the patient's skin, preventing the device from sliding due to operation touch or slight changes in the patient's body position during the operation.

[0029] Please see the appendix Figure 2 - Appendix Figure 6 The positioning component 2 includes a first limiting block 201, the outer wall of which is fixedly connected to the outer wall of the positioning seat 1.

A first bolt 211 is threadedly connected to the inner wall of the fixing block 210. A rubber top block 212 is fixedly connected to the bottom end of the first bolt 211. Specifically, the suction cup 204 is used to fix the device to the skin surface of the patient's shoulder joint through suction force, achieving temporary fixation of the device and preventing slippage during surgery. This ensures precise guidance for anchor implantation. The rubber top block 212 is made of medical-grade silicone. When the first bolt 211 pushes it to press against the patient's skin, it increases the friction between the rubber top block and the skin, further improving the stability of the device. By rotating the first bolt 211, medical staff can move the rubber top block 212 up and down, thereby adjusting the contact pressure between the rubber top block 212 and the patient's skin. When the rubber top block 212 is pressed against the patient's skin, it works in conjunction with the suction cup 204 to achieve double fixation of the device, further improving the stability of the device's positioning and preventing slippage due to operation, contact, or changes in the patient's position during surgery. Specifically, the suction cup 204 is used to fix the device to the skin surface of the patient's shoulder joint through suction force, achieving temporary fixation of the device and preventing it from sliding during the operation. This ensures precise guidance for anchor implantation. The rubber top block 212 is made of medical-grade silicone. When the first bolt 211 pushes it to press against the patient's skin, it increases the friction between the rubber top block and the skin, further improving the stability of the device.

The outer wall of the second rotating rod 301 is fixedly connected to the outer wall of the third limiting block 209. A disc 302 is fixedly connected to the outer wall of the second rotating rod 301. The adjusting assembly 3 also includes a second bolt 305, the outer wall of which is threadedly connected to the inner wall of the limiting box 307. A limiting ball 306 is fixedly connected to the bottom end of the second bolt 305. The outer wall of the limiting ball 306 abuts against the inner wall of the second rotating ball 303. A third rotating rod 304 is fixedly connected to the outer wall of the second rotating ball 303.

[0031] Specifically, the outer wall of the second rotating ball 303 is fixedly connected to the second rotating rod 301 and the third rotating rod 304, which can drive the second rotating rod 301 and the third rotating rod 304 to rotate synchronously, thereby driving the guide assembly 4, the locking assembly 6, and the observation assembly 7 to rotate together, achieving multi-angle adjustment of the guide tube 401 to adapt to different angle requirements for anchor implantation, ensuring that the guide tube 401 can be accurately aligned with the anchor implantation point. The second rotating ball 303 can rotate flexibly on the inner wall of the limiting box 307, and the rotation angle can be flexibly adjusted, while maintaining stability during rotation. It remains stable and will not jam or shift, allowing medical staff to quickly adjust the angle of the guide component 4 according to the surgical field and the anchor placement position. By rotating the second bolt 305, medical staff can push the limiting ball 306 at its bottom to move up and down. When the limiting ball 306 presses against the second rotating ball 303, the position of the second rotating ball 303 can be fixed by friction, ensuring that the guide component 4 will not rotate after being adjusted to the correct position. This ensures the stability of the guide tube 401 during anchor placement and avoids deviation of the anchor placement position due to the shift of the guide tube 401.

The depth limiting assembly 5 includes a limiting ring 501, the inner wall of which is slidably connected to the outer wall of the guide tube 401. An adjusting bolt 502 is threadedly connected to the inner wall of the limiting ring 501. A limiting rod 503 is fixedly connected to the outer wall of the limiting ring 501. Specifically, the guide tube 401 provides an implantation guide channel for the anchor, ensuring that the anchor can be accurately implanted into the rotator cuff tissue along the axial direction of the guide tube 401, avoiding displacement or tilting during anchor implantation, and ensuring accurate depth and angle of anchor implantation, thus guaranteeing the effectiveness of rotator cuff repair. The guide sleeve 403, through the cooperation of the positioning pin 404 and the guide funnel 402, firmly fixes the guide sleeve 403 in the designated position of the guide funnel 402, preventing the guide sleeve 403 from sliding up and down during the operation. The guide sleeve 403 can move along the guide funnel... The outer wall of the bucket 402 slides flexibly up and down, adjusting its position according to the specifications and length of the anchor, thereby adjusting the effective length of the guide channel to adapt to the implantation needs of anchors of different lengths and diameters, and to various surgical scenarios. It controls the implantation depth of the anchor. The limiting ring 501 can move flexibly up and down along the guide tube 401. Medical staff can adjust the limiting ring 501 to the corresponding position according to the preset implantation depth of the anchor in the surgical plan. When the anchor is implanted to the position of the limiting ring 501, the limiting ring 501 will form a physical block to prevent the anchor from going deeper.

The rotation of the output end of the motor 606 drives the rotating column 607 to rotate. The rotating column 607 is used to connect and transmit the motor 606 and the second gear 608. The second gear 608 is used to convert the rotational motion of the rotating column 607 into the horizontal linear motion of the second rack 610. The clamp 611 is used to limit the anchor after the anchor is put into the guide tube 401, to prevent the anchor from deviating or shaking during the implantation process, and to ensure that the anchor can move along the axial direction of the guide tube 401.

Specifically, the third gear 701 is used to convert the rotational motion of the limiting post 602 into the horizontal linear motion of the third rack 702. The second rack 610 can limit the second slider 703, ensuring that the second slider 703 always moves along a horizontal straight line during the movement. The depth scale 705 is used to display the relative depth of the anchor. Medical staff can observe the scale of the depth scale 705 to judge the height of the clamp 611 and the implantation depth of the anchor, avoiding the anchor being implanted too deep or too shallow, ensuring that the clamp 611 can be aligned with the anchor, adapting to the fine observation needs of shoulder arthroscopy, and facilitating medical staff to quickly read relevant data when the surgical field of view is limited.
