Description

Technical Field

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

[0002] Rotator cuff injuries are a common sports injury, frequently occurring in people who engage in high-intensity shoulder activities for extended periods, such as athletes and manual laborers. With increased awareness of exercise and the aging population, the incidence of rotator cuff injuries is rising annually, severely impacting patients' daily lives and motor function. Currently, clinical treatment for rotator cuff injuries is mainly divided into conservative treatment and surgical treatment. Conservative treatment is suitable for patients with mild injuries, relieving symptoms through immobilization, physical therapy, and medication. However, for moderate to severe injuries, surgical treatment remains the primary means of restoring shoulder function. In surgical treatment, direct suturing is the most basic method. Its principle is to directly pull the torn rotator cuff tissue together and suture it with sutures, relying on the tissue's own healing ability to achieve repair. Anchor fixation of the patch uses anchors implanted in the bone to fix the patch to the injured site with sutures. The mechanical interlocking force between the anchor and the bone tissue, as well as the support of the patch, enhance the repair effect. Bio-adhesive bonding uses biocompatible adhesive to bond the damaged tissue or patch to the surrounding tissue, achieving fixation through the chemical adhesion of the adhesive. However, existing technologies have significant limitations in real-world clinical scenarios. For example, during postoperative rehabilitation training, athletes often experience implant displacement at directly sutured repair sites due to insufficient fixation strength during shoulder exertion, as simple tissue suturing cannot withstand repeated traction forces. Patients using anchor fixation are prone to pain or even secondary injury due to localized stress concentration in the bone tissue around the anchors during shoulder rotation movements, as the rigid fixation of the anchors concentrates the load at a few contact points. Elderly patients using bio-adhesive bonding experience loosening at the adhesive site due to adhesive strength decay during long-term daily activities, as the adhesive strength and durability are insufficient to meet long-term mechanical requirements, failing to achieve the uniform load distribution and secure bonding of interwoven structures. Therefore, this invention provides a novel implant suitable for soft tissue repair to address the shortcomings of existing technologies. Summary of the Invention

The drive assembly 8 includes a turntable 801 located inside the implanter housing 1. One side of the turntable 801 is fixedly connected to the top of the rotating rod 207. The implanter housing 1 has a cavity inside, and two rubber buffer blocks 802 are fixedly connected inside the cavity. A guide ring 803 is fixedly connected to the inner side of the rubber buffer block 802. A movable rod 804 is slidably connected to the inner side of the guide ring 803.

[0021] Specifically, this implanter mainly consists of an implanter shell 1, a handle assembly 2, a combination assembly 6, a sleeve 3, a needle 4, a vibration mechanism 7, and a drive assembly 8.

[0022] A handle assembly 2 is provided on one side of the implant housing 1, providing a gripping area for the operator to facilitate operation. The handle assembly 2 includes a handle base 201, one end of which is securely fixed to the outside of the implant housing 1, providing a mounting base for subsequent structures. Two slots 202 are formed at the bottom of the handle base 201, and slots 203 are formed on both sides of the inner wall of the slots 202. These two structures are used for connection and engagement with the assembly 6.

[0023] A rotating rod 207 is rotatably connected inside the grip base 201. The rotating rod 207 can rotate smoothly within the grip base 201. A combined tube 204 is fixedly connected to the bottom of the rotating rod 207, and the combined tube 204 rotates together with the rotating rod 207. An L-shaped groove 205 is formed on the outer side of the combined tube 204, and a limiting groove 206 is formed on the inner side of the L-shaped groove 205. These groove structures are used to cooperate with the combined rod 610 in the combined assembly 6 to realize power transmission and motion control. A spring 208 is fixedly connected inside the rotating rod 207, and a pressure plate 209 is fixedly connected to the bottom end of the spring 208. The spring 208 provides elastic force, which acts on other components through the pressure plate 209 to ensure the stability of the structural connection.

[0024] A combination component 6 is provided on the outer side of the handle assembly 2. The combination component 6 works in conjunction with the handle assembly 2 to add additional functionality to the implant. The combination component 6 includes a connecting shell 601, which is part of the shaving tool and is modularly combined with the implant shell 1. The top of the connecting shell 601 fits against the bottom of the handle base 201. Two inserts 602 are fixedly connected to the top of the connecting shell 601, and locking beads 603 are fixedly connected to both sides of the outer side of each insert 602. During installation, the inserts 602 are inserted into the slots 202, at which point the locking beads 603 will engage in the slots 203, achieving initial horizontal fixation of the connecting shell 601 and the handle base 201.

[0025] A motor 604 is installed inside the connecting housing 601, serving as a power source to power the subsequent transmission structure. A transmission column 605 is fixedly connected to the output end of the motor 604, driving the transmission column 605 to rotate after the motor 604 starts. Two fixing blocks 606 are fixedly connected to the outer side of the transmission column 605, and a sliding sleeve 607 is slidably connected to the outer side of the transmission column 605. Two slotted holes 608 are formed on the outer side of the sliding sleeve 607. The outer side of the fixing blocks 606 is slidably connected to the inner side of the slotted holes 608. Thus, when the transmission column 605 rotates, the sliding sleeve 607 rotates through the cooperation of the fixing blocks 606 and the slotted holes 608. An operating ring 609 is fixedly connected to the outer side of the sliding sleeve 607, allowing the operator to easily operate the sliding sleeve 607, such as moving it up and down, by pinching the operating ring 609.

[0026] A combination rod 610 is fixedly connected to the outer side of the sliding sleeve 607. The outer side of the combination rod 610 is slidably connected to the inner side of the L-shaped groove 205 and the limiting groove 206. The outer side of the sliding sleeve 607 is slidably connected to the inner side of the combination tube 204. The top of the sliding sleeve 607 is in contact with the bottom of the pressure plate 209. During installation, the sliding sleeve 607 is lifted by pinching the operating ring 609, so that the sliding sleeve 607 is inserted into the combination tube 204, and the combination rod 610 will enter the inner side of the L-shaped groove 205. Then, it is squeezed by the spring 208 and locked into the limiting groove 206. In this way, the outer shell 601 and the handle seat 201 are connected and installed, and the power can be transmitted from the motor 604 to the rotating rod 207.

[0027] A sleeve 3 is fixedly connected to one end of the implant housing 1, which serves for positioning and protection. A needle 4 is placed inside the sleeve 3, which is used to pierce the patient's skin and muscles. Multiple oblique grooves 5 are opened on the outer side of the needle 4. The oblique grooves 5 are inclined notches with barbs. During operation, they can continuously insert fibers from the non-woven fabric into the patient's muscles, forming an interwoven pattern.

[0028] The implant housing 1 houses a drive assembly 8, which converts the power transmitted from the handle assembly 2 into the reciprocating motion of the needle 4. The drive assembly 8 includes a turntable 801 located inside the implant housing 1. One side of the turntable 801 is fixedly connected to the top of the rotating rod 207. When the rotating rod 207 rotates, it drives the turntable 801 to rotate synchronously. The implant housing 1 has an internal cavity, and two rubber buffer blocks 802 are fixedly connected inside the cavity. The rubber buffer blocks 802 are made of elastic material and serve to cushion and absorb shock.

[0029] A guide ring 803 is fixedly connected to the inner side of the rubber buffer block 802. A movable rod 804 is slidably connected to the inner side of the guide ring 803. The guide ring 803 limits the movement of the movable rod 804, allowing it to reciprocate only along the direction of the guide ring 803. A strip frame 805 is fixedly connected to the near ends of the two movable rods 804. A lever 806 is fixedly connected to the top of the turntable 801, with the outer side of the lever 806 slidably connected to the inner side of the strip frame 805. When the turntable 801 rotates, the lever 806 rotates accordingly, causing the strip frame 805 to move. Due to the limiting effect of the guide ring 803, the movable rod 804 reciprocates along the guide ring 803. One end of the other movable rod 804 is fixedly connected to one end of the needle 4, allowing the needle 4 to reciprocate.

[0030] A vibration mechanism 7 is provided at the other end of the implanter housing 1. The vibration mechanism 7 is used to generate slight vibration of the needle 4 to facilitate insertion into the patient's muscle. The vibration mechanism 7 includes an outer shell 701, the outer side of which fits against the outer side of the implanter housing 1. A T-shaped block 702 is fixedly connected to the outer side of the outer shell 701. A T-shaped groove 703 is provided on the outer side of the implanter housing 1. During installation, the outer shell 701 is assembled onto the outside of the implanter housing 1 so that the two fit together externally. At the same time, the T-shaped block 702 is inserted into the interior of the T-shaped groove 703 to achieve initial positioning.

[0031] An arc-shaped hanging plate 704 is rotatably connected to the top of the outer shell 701, and a hanging rod 705 is fixedly connected to the top of the implanter shell 1. Rotating the arc-shaped hanging plate 704 causes its outer side to hook onto the hanging rod 705, thus stably installing the outer shell 701 on the outside of the implanter shell 1. A second motor 706 is installed inside the outer shell 701, serving as the power source for the vibration mechanism 7. A cam 707 is fixedly connected to the output end of the second motor 706. After the second motor 706 starts, it drives the cam 707 to rotate. The outer side of the cam 707 contacts the outer side of one of the movable rods 804. During the rotation of the cam 707, it continuously collides with the movable rod 804. Because the rubber buffer block 802 is made of elastic material, the movable rod 804 can cause the needle 4 to vibrate slightly.

[0032] During operation, the device is first assembled. The outer shell 701 is assembled onto the outside of the implanter shell 1, ensuring a close external fit. Simultaneously, the T-shaped block 702 is inserted into the T-shaped groove 703. Then, the arc-shaped hanging piece 704 is rotated so that its outer side is fastened onto the hanging rod 705, ensuring the outer shell 701 is stably installed on the outside of the implanter shell 1. Next, the connecting shell 601 is combined with the handle base 201. First, the insert block 602 is inserted into the slot 202, at which point the retaining bead 603 will engage in the retaining groove 203. At the same time, the operating ring 609 is pinched to lift the sliding sleeve 607, causing the sliding sleeve 607 to insert into the combination tube 204. The combination rod 610 then enters the inside of the L-shaped groove 205 and, under the pressure of the spring 208, engages in the limiting groove 206. Thus, the connecting shell 601 and the handle base 201 are installed.

[0033] The motor 604 is started, driving the transmission column 605 to rotate. This, in turn, drives the sliding sleeve 607 to rotate via the fixed block 606, transmitting power to the rotating rod 207, which in turn rotates the turntable 801. During the rotation of the turntable 801, the lever 806 moves the strip frame 805. Because the guide ring 803 limits the movement of the movable rod 804, the movable rod 804 reciprocates along the guide ring 803, causing the needle 4 to reciprocate. At this point, the non-woven fabric is placed on the patient's skin, with the end of the sleeve 3 pressing against it. The needle 4 continuously pierces the non-woven fabric and then into the patient's muscle. The oblique groove 5 on the needle 4 has a barbed, angled notch that allows the fibers from the non-woven fabric to continuously penetrate the patient's muscle, forming an interwoven pattern.

[0034] Simultaneously, motor 706 is activated, driving cam 707 to rotate, which in turn collides with movable rod 804. Since rubber buffer block 802 is made of elastic material, movable rod 804 can cause needle 4 to vibrate slightly, making it easier to insert into the patient's muscle and allowing oblique groove 5 to more easily catch the non-woven fabric fibers and move downward, achieving a firm bond between the implant and the tissue to be repaired, improving fixation strength. The interwoven structure achieves uniform load distribution of the implant, avoiding local stress concentration.

[0035] Working principle: First, the outer shell 701 can be assembled on the outside of the implant housing 1, so that the two fit together externally. At the same time, the T-shaped block 702 is inserted into the inside of the T-shaped groove 703. Then, the arc-shaped hanging piece 704 is rotated so that its outer side is fastened to the hanging rod 705, so that the outer shell 701 is stably installed on the outside of the implant housing 1. Then, the connecting shell 601 and the handle seat 201 are combined. The connecting shell 601 is used as part of the planer and is modularly combined with the implant housing 1. First, the insert block 602 is inserted into the inside of the slot 202. At this time, the retaining bead 603 will be inserted into the slot 203. At the same time, the operating ring 609 is pinched to lift the sliding sleeve 607, so that the sliding sleeve 607 is inserted into the combination tube 204, and the combination rod 610 will enter the inside of the L-shaped groove 205. Then, it is squeezed by the spring 208 and inserted into the limiting groove 206. Thus, the connecting shell 601 and the handle seat 201 are installed. The starter motor 604 drives the transmission column 605 to rotate, which in turn drives the sliding sleeve 607 to rotate via the fixed block 606. This transmits power to the rotating rod 207, causing the turntable 801 to rotate. The lever 806 then moves the strip frame 805. Because the guide ring 803 limits the movement of the movable rod 804, the movable rod 804 reciprocates along the guide ring 803, causing the needle 4 to reciprocate. This places the non-woven fabric on the patient's skin, with the end of the sleeve 3 pressing against the fabric. The needle 4 then continuously pierces the non-woven fabric and enters the patient's muscle. The oblique groove 5 on the needle 4... It has a barbed, inclined notch that allows the fibers in the nonwoven fabric to be continuously inserted into the patient's muscle, forming an interwoven structure. The motor 706 drives the cam 707 to rotate, which in turn collidees with the movable rod 804. Since the rubber buffer block 802 is made of elastic material, the movable rod 804 can drive the needle 4 to produce slight vibration, which makes it easier to insert into the patient's muscle and allows the oblique groove 5 to more easily catch the nonwoven fabric fibers and move downward, achieving a firm bond between the implant and the tissue to be repaired, improving the fixation strength. The interwoven structure achieves a uniform load distribution of the implant and avoids local stress concentration. Additionally, when the operator's skill level is low or the implantation procedure is complex and requires a more stable operating environment, the operator can insert a finger into the hole on the cover plate 709 to open the cover plate 709, then pour out the guide block 901 from the storage compartment 708, and place the guide block 901 on the non-woven fabric. The guide block 901 can be secured by clamping the annular groove 904 with medical forceps, or by pinching the outside of the guide block 901 with fingers. Alternatively, tape can be attached to one side of the guide block 901 to adhere it to the patient's skin. When the curved end of the sleeve 3 is aligned with the concave groove 902, the needle 4 can be inserted into the skin at a 90-degree angle. The guide groove 903 has a larger space at one end, making it easier to adjust the insertion angle, ensuring that the needle 4 implantation procedure meets the 60-90 degree implantation standard. When the guide block 901 is no longer needed, it can be placed back into the storage compartment 708. The connection between the cover plate 709 and the outer shell 701 uses a magnetic design for easy opening and closing.
