Background

Osteochondral injury has long been a problem that plagues sports medicine. Periosteum-bone complex transplantation has recently received much attention at home and abroad due to its advantages of safety, economy, high feasibility, few complications, and the like. Depending on the chondrogenic properties of the periosteum and the natural stability between the periosteum and the bone, periosteum-bone complex transplantation can repair cartilage and subchondral bone lesions simultaneously, and is particularly suitable for talar cartilage damage accompanied by cystic degeneration. The existing research shows that the long-term clinical curative effect in the operation is definite, and the postoperative patient is obviously benefited.

However, the key to the success of repairing osteochondral injuries using this surgical approach is two core problems during surgery: the first one is to obtain the complete periosteum-bone complex, to the utmost extent, to keep the integrity of the periosteum on the tissue structure and the internal mechanical stability of the periosteum and the bone, to reduce the possibility of stripping and falling of the periosteum after transplantation, to eliminate the secondary healing between the periosteum and the bone, thereby ensuring the normal function of the periosteum to form cartilage. And secondly, the implantation process needs to ensure that the graft is accurately matched and tightly attached to the bone groove of the recipient area, so that 'dead space' caused by poor matching between the graft and the bone groove is eliminated, graft loosening caused by unstable attachment is prevented, primary healing of the graft and the bone groove is ensured, and the recurrent cystic degeneration after the transplantation is avoided. Existing harvesting/transplanting tools do not solve the two core problems well.

In this embodiment, since the prior art takes grafts: obtaining the periosteum-bone complex implant needs to use a bone hammer to knock a periosteum knife to cut the periosteum and the cortex of the bone complex, then withdraw the periosteum knife, and manually drill the complete periosteum-bone complex by using a trepan with the same diameter as the periosteum knife. The existing manual periosteum knife has two problems in the using process: firstly, an operator only holds the bone graft with hands in the operation, a reliable fixing mode is lacked, and the periosteum at the edge of the periosteum-bone complex graft is easy to shift by knocking a periosteum knife, so that the periosteum at the edge of the periosteum-bone complex graft is separated from the lower cortical bone; secondly, the blade of the periosteum knife is easy to damage after repeated knocking. Because the periosteum is difficult to be completely cut off by the repeatedly used manual periosteum knife, when the periosteum knife is withdrawn and the periosteum-bone complex is drilled by the manual periosteum saw, the periosteum in the transplantation area is stripped or even falls off in the process of rotary cutting of the manual periosteum saw. The existing manual trepan has the two problems in the using process. In addition, the graft is difficult to accurately obtain according to the depth of the donor area by the manual instrument, the operation process depends on the experience of an operator, and the standardization is difficult to realize;

for implant grafts: the pressure reducer is used for knocking the graft in the trepan into the bone groove, so that cancellous bone at the lower layer of the graft is compressed, the surface of the graft is ensured to be 1mm lower than surrounding cartilage tissue, and the graft is ensured to be tightly attached to the bone groove of the accepting area. However, the existing surgical instruments have the following problems: the position of the broken end of the graft obtained by shaking the hand trephine back and forth and left and right is often uncontrollable, so that the length of the obtained graft is not matched with the depth of a bone groove, and due to the lack of an observation window, the implantation process is often 'blind knocking'. This energy can lead to two consequences, first: the length of the graft is too long relative to the depth of the bone column, in order to achieve the purpose that the surface of the graft is 1mm lower than the surrounding normal tissues, a metal pressure reducer can be used for repeatedly knocking the graft in the operation, the damage and the integrity damage of the periosteum are finally caused, and the transplanted periosteum is difficult to play a cartilage forming role after the operation; secondly, the method comprises the following steps: the length of the graft is too short relative to the depth of the bone column, and the result of complete knock-in of the graft is an oversized recess of the surface of the graft relative to the surrounding normal cartilage, whereas our clinical experience and published studies have demonstrated that a recess of 1mm is the optimal depth, with more than 1mm potentially resulting in difficulty in forming a sufficient defect for filling with regenerated cartilage after implantation, and less than 1mm potentially resulting in a height of regenerated cartilage exceeding the surrounding normal cartilage after implantation. In addition, tapping the periosteum by a metal pressure reducer can reduce damage to the periosteum, but we confirmed by more than 150 periosteum-bone complex grafting surgeries and more than 20 postoperative 1-year secondary arthroscopic exploration: the way the graft is knocked through the stress-reducer can still result in damage to the integrity of the periosteal structure.

Referring to fig. 7 to 9, the present invention further provides a method for using the electric periosteum and bone complex, comprising the following steps:

s1: before use, a 1mm Kirschner wire is driven into a supply area, the central positioning electric periosteum knife 1 is inserted, the central positioning periosteum knife is fixed by the Kirschner wire, an electric drill is connected, and a periosteum and cortex lycii bone complex is cut to a depth of 5 mm;

s2: then the central positioning electric periosteum cutter 1 is withdrawn, the central positioning electric trephine 2 with the same diameter is inserted along the Kirschner wire, and the central positioning electric trephine is drilled into the cortical/cancellous bone to a desired depth;

s3: then withdrawing the central positioning electric trepan 2, withdrawing the kirschner wire, inserting the T-shaped visible bone taking/grafting sleeve 5 with the same diameter along the cutting track of the central positioning electric trepan 2, confirming the depth of the graft through the window 512, and shaking the T-shaped visible bone taking/grafting sleeve 5 forwards, backwards, leftwards and rightwards to obtain the periosteum-bone complex graft with the ideal depth; observing the position of the broken end of the periosteum-bone complex graft through the window, if the broken end is positioned above the opening of the T-shaped visible bone taking/grafting sleeve 5, inserting the soft head bone pushing rod 3 with the diameter smaller than that of the T-shaped visible bone taking/grafting sleeve 5 by 1mm from the tail end of the T-shaped visible bone taking/grafting sleeve 5, properly knocking the soft head bone pushing rod 3, and enabling the broken end of the periosteum-bone complex graft to be flush with the opening of the T-shaped visible bone taking/grafting sleeve 5;

s4: drilling bone grooves with corresponding sizes in a lesion area according to the size and the depth of a lesion so as to completely remove the lesion;

s5: confirming the length of the implant by observing the window 512, implanting a proper amount of allogeneic bone into the bone groove by using the bone grafting rod 4, knocking the second handheld grab handle 42, compacting the bone bed below the bone groove, measuring the depth of the bone groove by using a scale on the outer wall of the bone grafting rod 4, ensuring that the depth of the bone groove is 1mm lower than that of the implant in the T-shaped visible bone taking/grafting sleeve 5, and completing the preparation before implantation;

s6: and then inserting the T-shaped visual bone taking/grafting sleeve 5 embedded with the graft into a bone groove, confirming that the graft is embedded into the bone groove through the window 512, wherein the surface of the T-shaped visual bone taking/grafting sleeve is slightly higher than the cartilage surface around the bone groove, inserting the cartilage pushing rod 3 with the diameter being 1mm smaller than that of the T-shaped visual bone taking/grafting sleeve 5 from the tail end of the T-shaped visual bone taking/grafting sleeve 5 to fix the graft, then reversely knocking the T-shaped handle 52, withdrawing the T-shaped visual bone taking/grafting sleeve 5, knocking the surface of the graft to a position 1mm lower than the surrounding normal cartilage by the bone pushing rod 31, and then completing the implantation process.

Wherein, if the basal part of the implant is not level with the head end of the T-shaped visual bone taking/grafting sleeve 5, the soft head bone pushing rod 3 is adopted to knock downwards from the periosteum end of the implant until the lower part of the implant is level with the head end of the visual bone taking/grafting sleeve.

The electric periosteum and bone complex transplanting kit and the using method provided by the invention can obtain a complete periosteum and bone complex, so that the periosteum is prevented from falling off after transplantation, and in addition, the graft is required to be tightly attached to a bone groove of a receiving area in the implanting process, and the postoperative recurrent capsulopathy is avoided to the maximum extent.

Specifically, the graft was harvested: compare with the process that current apparatus obtained the graft, be different from the manual work and hold fixed periosteum sword, strike periosteum sword and combine manual trephine to bore and get the graft, novel surgical instruments adopts ke shi needle location fixed, and the electric drill cuts the periosteum, bores and gets the graft. Novel surgical instruments can solve the problem of periosteum and below cortex bone separation, reduce the artificial loss to the apparatus of strikeing, promote the durability of apparatus. In addition, the periosteum-bone complex bone column obtained by the electric drill is more standard in length and shape through the kirschner wire positioning and fixing, the standardization of operation can be realized, and the difference of postoperative curative effect caused by the difference of operation skill of an operator is reduced.

The implantation process comprises the following steps: the graft obtained by the hand-operated T-shaped visual bone harvesting/grafting sleeve 5 has a certain error from the ideal length because the broken end may not be at the root. The bone graft rod 4 (with scale) filling the bone groove with bone graft can counteract this error and ensure that the graft fits into the bone groove. Compared with the traditional surgical tool, the novel surgical tool provided by the invention can ensure that the implantation and transplantation process can be completed at one time, and the risks of damage to periosteum caused by repeated operation and falling of the implant in the operation are reduced. The whole process can realize accurate operation, and the purpose that the surface of the transplanted plant is 1mm lower than the surrounding normal cartilage after transplantation is achieved. In addition, the soft head bone pushing rod 3 is adopted to fix the implant, and the reverse knocking and withdrawing operation of the T-shaped visual bone taking/grafting sleeve 5 can avoid the damage to periosteum when the existing surgical instrument is used for knocking the implant.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
