Description

Technical Field

[0001] The present invention relates to the technical field of orthopedics, and in particular to an electric periosteum and bone complex transplant kit and a use method thereof. Background Art

[0002] Osteochondral injuries have long been a problem plaguing sports medicine. Periosteum-bone complex transplantation has garnered widespread attention in recent years, both domestically and internationally, due to its safety, affordability, high feasibility, and minimal complications. Relying on the chondrogenic properties of the periosteum and the natural stability between the periosteum and bone, periosteal-bone complex transplantation can simultaneously repair cartilage and subchondral bone lesions, making it particularly suitable for talar osteochondral injuries associated with cystic changes. Current studies have demonstrated that this procedure has definite long-term clinical efficacy, with significant benefits for patients after surgery.

[0003] However, the key to successfully repairing osteochondral damage using this surgical method lies in two core issues during the operation: the first is to obtain a complete periosteum-bone complex, to preserve the integrity of the periosteum in tissue structure and the intrinsic mechanical stability of the periosteum and bone to the greatest extent, to reduce the possibility of periosteum peeling and falling off after transplantation, to eliminate secondary healing between the periosteum and bone, and thus ensure that the periosteum can perform its normal cartilage-forming function. The second is that the implantation process must ensure that the graft and the bone groove of the recipient area are accurately matched and tightly fitted, to eliminate the "dead space" caused by poor matching between the graft and the bone groove, to prevent the graft from loosening due to unstable fitting, to ensure the primary healing of the graft and the bone groove, and thus to avoid recurrence of cystic changes after transplantation. However, the existing extraction / transplantation tools cannot solve these two core problems well. Summary of the Invention

The soft-headed bone pusher with a diameter 1 mm smaller than the T-shaped visual removal / bone grafting sleeve is inserted from the tail end to fix the graft, and then the T-shaped handle is knocked in the reverse direction to withdraw the T-shaped visual removal / bone grafting sleeve. The bone pusher knocks the graft surface to a position 1 mm lower than the surrounding normal cartilage to complete the implantation process.

In this way, a complete periosteal bone complex can be obtained, thereby ensuring that the periosteum does not fall off after transplantation.

[0050] In this embodiment, due to the prior art of obtaining the graft: obtaining the periosteal-bone complex graft requires using a bone hammer to strike the periosteal knife to cut the periosteum and cortical bone complex, and then withdrawing the periosteal knife and using a ring saw with the same diameter as the periosteal knife to manually drill the complete periosteum-bone complex. The existing manual periosteal knife has two problems during use: First, it only relies on the surgeon to hold it with both hands during the operation, and lacks a reliable fixation method. The periosteal knife is easily displaced when struck, resulting in the periosteum at the edge of the periosteal-bone complex graft being separated from the cortical bone below; Second, the blade of the periosteal knife is easily damaged after repeated striking. Since it is difficult to completely cut the periosteum with a manual periosteal knife that is used repeatedly, when the periosteal knife is withdrawn and replaced with a manual bone saw to drill the periosteum-bone complex, the periosteum in the transplant area is peeled off or even falls off during the rotation and cutting of the manual bone saw. The existing manual ring saw also has the above two problems during use. In addition, it is difficult to accurately obtain the graft according to the depth of the donor area using the above manual instruments. The surgical process relies on the experience of the surgeon and is difficult to achieve standardization.

[0051] For implanted grafts, a pressure reducer is used to hammer the graft from the trephine into the bone socket, compressing the cancellous bone beneath the graft and ensuring that the graft surface is 1mm lower than the surrounding cartilage tissue, ensuring a tight fit between the graft and the recipient bone socket. However, existing surgical instruments have the following issues: The position of the graft ends obtained by manually shaking the trephine back and forth and left and right is often uncontrollable, resulting in a mismatch between the length of the graft and the depth of the bone socket. Due to the lack of an observation window, the implantation process is often "blind knocking." This can lead to two consequences. First, the graft is too long relative to the depth of the bone column. To achieve a 1mm lower surface than the surrounding normal tissue, repeated periosteal tapping with a metal pressure reducer may be necessary during surgery, ultimately damaging the periosteum and disrupting its integrity, making it difficult for the graft to function as a cartilage graft after surgery. Second, the graft is too short relative to the depth of the bone column. Completely tapping the graft into the bone column results in a large indentation of the graft surface relative to the surrounding cartilage. Our clinical experience and published studies have confirmed that a 1mm indentation is the optimal depth. A depth exceeding 1mm may prevent adequate regenerated cartilage from filling the defect after grafting, while a depth below 1mm may result in the regenerated cartilage exceeding the surrounding normal cartilage. Furthermore, while tapping the periosteum with a metal pressure reducer can reduce periosteal damage, our experience with over 150 periosteum-bone complex grafts and subsequent arthroscopic exploration in over 20 cases one year after surgery confirms that tapping the graft with a pressure reducer still compromises the integrity of the periosteum.

[0052] The graft tool in the prior art comprises a circular periosteal knife and a trephine drill. The circular periosteal knife is a hollow tubular structure with an inner diameter ranging from 7 to 15 mm, a length of 100 mm, a tube wall of 1 mm, and a flat blade.

The scale ranges from 0 to 25 mm, with the scale starting at the front end of the fourth metal rod 41. During use, the corresponding diameter of the bone pusher 31 is selected based on the diameter of the bone trough.

[0055] See also Figures 7 to 9 The present invention also provides a method for using the electric periosteum and bone complex, comprising the following steps:

[0056] S1: Before use, insert a 1mm Kirschner wire into the donor area, insert the center positioning electric periosteal knife 1, fix the center positioning periosteal knife with the Kirschner wire, connect the electric drill, and cut the periosteum and osteodermis-bone complex to a depth of 5mm;

[0057] S2: The center-positioned electric periosteal knife 1 is then withdrawn, and the center-positioned electric trephine 2 with the same diameter is inserted along the Kirschner wire to drill into the cortical / cancellous bone to the desired depth;

[0058] S3: Then, the center-positioning electric ring saw 2 and the Kirschner wire are withdrawn, and the T-shaped visual removal / bone grafting sleeve 5 of the same diameter is inserted along the cutting track of the center-positioning electric ring saw 2. The graft depth is confirmed through the window 512, and the T-shaped visual removal / bone grafting sleeve 5 is shaken back and forth and left and right to obtain the ideal depth of the periosteal-bone complex graft; the position of the broken end of the periosteal-bone complex graft is observed through the window. If the broken end is above the opening of the T-shaped visual removal / bone grafting sleeve 5, the soft-headed bone pusher 3 with a diameter 1 mm smaller than the T-shaped visual removal / bone grafting sleeve 5 is inserted from the tail end of the T-shaped visual removal / bone grafting sleeve 5, and the soft-headed bone pusher 3 is tapped appropriately to move the broken end of the periosteal-bone complex graft to a position flush with the opening of the T-shaped visual removal / bone grafting sleeve 5;

[0059] S4: Drill a bone groove of corresponding size in the lesion area according to the size and depth of the lesion to completely remove the lesion;

[0060] S5: Confirm the length of the graft by observing the window 512, implant an appropriate amount of allogeneic bone into the bone groove using the bone grafting rod 4, tap the second handheld handle 42 to compact the bone bed below the bone groove, and measure the depth of the bone groove using the ruler on the outer wall of the bone grafting rod 4 to ensure that the depth of the bone groove is 1 mm lower than the graft in the T-shaped visual removal / bone grafting sleeve 5, thus completing the pre-implantation preparation;

[0061] S6: Then, the T-shaped visual removal / bone grafting sleeve 5 embedded with the graft is inserted into the bone groove, and the graft is confirmed to be embedded in the bone groove through the window 512, and its surface is slightly higher than the cartilage surface around the bone groove. The soft-headed bone pusher 3 with a diameter 1 mm smaller than the T-shaped visual removal / bone grafting sleeve 5 is inserted from the tail end to fix the graft, and then the T-shaped handle 52 is knocked in the reverse direction to withdraw the T-shaped visual removal / bone grafting sleeve 5. The bone pusher 31 knocks the graft surface to a position 1 mm lower than the surrounding normal cartilage to complete the implantation process.

[0062] If the base of the graft is not flush with the head of the T-shaped visual removal / bone grafting sleeve 5, a soft-headed bone pusher 3 is used to knock downward from the periosteal end of the graft until the bottom of the graft is flush with the head of the visual removal / bone grafting sleeve.

[0063] The electric periosteum and bone complex transplant kit and usage method proposed in the present invention can obtain a complete periosteal bone complex, thereby ensuring that the periosteum does not fall off after transplantation. In addition, during the implantation process, it is necessary to ensure that the graft fits tightly with the bone groove of the recipient area to minimize postoperative recurrence of cystic changes.

[0064] Specifically, graft harvesting: Compared to the process of harvesting grafts using existing instruments, the new surgical instrument uses Kirschner wires for positioning and fixation, and an electric drill to cut the periosteum and extract the graft, rather than manually holding and fixing the periosteal knife and tapping the periosteal knife with a manual trephine. This new surgical instrument can resolve the problem of separation between the periosteum and the underlying cortical bone, reduce wear and tear on the instrument caused by manual tapping, and improve its durability. Furthermore, the periosteal-bone complex column harvested with an electric drill, using Kirschner wires for positioning and fixation, is more standardized in length and shape, enabling standardized surgical procedures and reducing differences in postoperative efficacy due to differences in surgical technique among surgeons.

[0065] Implantation process: The graft obtained by the hand-cranked T-shaped visual removal / bone grafting sleeve 5 often has a certain error in length from the ideal length because the broken end may not be at the root. The bone grafting rod 4 (with a ruler) fills the bone groove and grafts the bone to offset this error, ensuring that the graft matches the bone groove. Compared with traditional surgical tools, the new surgical tool proposed in the present invention can ensure that the implantation and transplantation process can be completed in one go, reducing the damage to the periosteum caused by repeated operations and the risk of the graft falling during the operation. The entire process can achieve precise operation, achieving the purpose of the graft surface being 1mm lower than the surrounding normal cartilage after transplantation. In addition, the soft-headed bone pushing rod 3 is used to fix the graft, and the reverse knocking operation to exit the T-shaped visual removal / bone grafting sleeve 5 can avoid damage to the periosteum when using existing surgical instruments to knock on the graft.

[0066] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
