Referring to fig. 2, the facet joint interface filling device according to the present invention includes an upper side plate 11, a lower side plate 12, a pointed cone 13, and an elastic body 14 between the upper side plate 11 and the lower side plate 12. The upper side plate 11, the lower side plate 12 and the pointed cone 13 are preferably formed by folding and pressing a whole plate. The pointed cone 13 can facilitate insertion of the facet joint filling device. The elastic body 14 may be made of, for example, a resin material or a rubber material, and may be a cylinder or a rectangular block; the elastic body 14 is attached to the inner surfaces of the upper and lower side plates 11, 12, and may be bonded or mechanically attached, such as riveted. The outer surfaces of the superior and inferior side plates 11, 12 may be provided with protrusions that may be utilized to stably maintain the facet joint filling device in the facet joint space between the vertebral bodies of the spine. Other accessories, such as threaded bushings, etc., may also be provided with the facet joint filling device.
Referring to fig. 3 (wherein the two distracting elements are separated for ease of description of the elastic bandage, in actual use, the two distracting elements are brought together) one embodiment of a spinal spinous process distraction device of the spinal condyle connection assembly in accordance with the present invention is shown. See also figures 4 and 5. The spinous process distraction device according to the present invention includes a first distraction element 810 and a second distraction element 820, the first distraction element 810 and the second distraction element 820 being generally of a U-shaped plate structure including two spaced apart legs and a U-shaped connection connecting the two legs, i.e., between the two legs; the U-shaped connection portions (i.e., away from the U-shaped open ends) of the first and second distracting elements 810, 820 are disposed opposite each other; the outer side surfaces of the first and second distraction elements 810 and 820 have first and second grooves 813 and 814, respectively, and the tops of the U-shaped legs of the first and second distraction elements 810 and 820 also have notches 818; the spinous process distraction device according to the present invention further comprises an elastic bandage 815, the elastic bandage 815 having an overall shape of an "8" (fig. 3), the elastic bandage 815 having a first set of elements 816 and a second set of elements 817, the first set of elements 816 being nested in the first groove 813 of the first distraction element 810, the second set of elements 817 being nested in the second groove 814 of the second distraction element 820; the first 816 and second 817 sets are also received in notches 818 in the tops of the U-shaped legs of the first 810 and second 820 spreader members, respectively. The elastic bandage 815 can be integrally formed, or formed by connecting multiple sections, or formed by connecting the ends. Where the first 816 and second 817 sets intersect, one portion of the elastic bandage 815 has a through hole 819 and another portion of the elastic bandage 815 has a smaller width than the whole of the bandage so as to pass out through said through hole 819. Preferably, the elastic bandage 815 may be made of a medical grade thermoplastic resin material. In the installation of the spinous process distraction device according to the present invention, firstly, the spinous process distraction device before use is substantially in the same line due to the elastic force of the elastic bandage 815, and when the use is started, the first distraction element 810 and the second distraction element 820 are bent against the restoring force of the elastic bandage, the openings of the first distraction element 810 and the second distraction element 820 are respectively received in the spinous processes of the upper and lower spinal bone segments, and then the first distraction element 810 and the second distraction element 820 are straightened to restore them to the same line, because the spinous processes of the upper and lower spinal bone segments are respectively pressed against the elastic bandage portions at the openings of the first distraction element 810 and the second distraction element 820, and thus the elastic bandage portions at the openings are pressed into the U-shaped interior of the distraction element until the first distraction element 810 and the second distraction element 820 are restored to the same line; meanwhile, as the length of the whole elastic bandage is obviously increased due to the propping of the spinous process, the elastic force of the elastic bandage after being installed in place is also obviously increased, at the moment, the first stretching element 810 and the second stretching element 820 are difficult to bend each other, the effective stretching of the upper spinal bone section and the lower spinal bone section is realized, on the other hand, under the action of external force (such as twisting, etc.), the elastic restoring force of the elastic bandage allows the first stretching element 810 and the second stretching element 820 to bend each other, thereby providing elasticity for the use of the spinous process stretching device, and simultaneously, the first stretching element 810 and the second stretching element 820 can be restored to the same straight line after the external force of a human body disappears. The spinal spinous process distraction device according to the present invention thus provides greater flexibility in use relative to prior art devices. Meanwhile, the spine spinous process is abutted against the elastic bandage, the elastic bandage can effectively buffer the action of the spine spinous process, abrasion of the spine spinous process can be prevented, and the spine spinous process is effectively protected. Preferably, protrusions are further provided at the corresponding positions of both sides of the U-shaped connection parts of the first and second stretching members 810 and 820, respectively, the protrusions covering the aforementioned grooves 813 and 814, so that the protrusions can function to prevent the elastic bandage from jumping out of the grooves. The middle parts of the U-shaped connecting parts of the first and second propping elements 810 and 820 are also respectively provided with a concave hole and a convex key, and the cooperation of the concave holes and the convex keys can further position the first and second propping elements 810 and 820 to prevent dislocation from occurring when in use. Preferably, both the recess and the tab have an arcuate shape, so that the flexing of the first and second distracting elements 810, 820 relative to each other is not significantly limited. Protrusions are further provided at corresponding positions of two sides of the U-shaped connection portion of the first and second stretching elements 810 and 820, respectively, so that the first and second stretching elements 810 and 820 can be prevented from being bent at an excessive angle, and a large elastic bandage restoring force needs to be overcome when the protrusions are passed. More preferably, guide grooves and sliding rails are further provided on two protrusions at corresponding positions of both sides of the U-shaped connection portion of the first and second spreader members 810 and 820, respectively, the sliding rails being in the guide grooves, so that guiding of the bending process of the first and second spreader members 810 and 820 with respect to each other can also be achieved, and the first and second spreader members 810 and 820 are prevented from being twisted with each other in directions different from the aforementioned bending directions. Preferably, the projection is adjustably mounted on the distracting element such that the projection can be positioned relatively close to the foot prior to installation, and can be moved to a position close to the U-shaped connection (i.e., closer to the central axis) and locked after installation. The arrangement is beneficial to the installation of the invention, and can more effectively prevent the situation that the two expanding elements are mutually bent beyond the limit and cannot be reset under special conditions. In this embodiment, the aforementioned arrangement of mating fittings further enhances the safety of the invention in use.
Fig. 6 illustrates one embodiment of a spinal spinous process distraction device of the spinal condyle connection assembly in accordance with the present invention. The first and second spreader members 910, 920 are generally U-shaped plate structures including two spaced apart legs and a U-shaped connection connecting the two legs, i.e., between the two legs; the two U-shaped legs are parallel to each other and are substantially perpendicular to a tangent to the lowest point (or apex) of the U-shaped connection. The U-shaped connection parts (namely, far away from the U-shaped open end) of the first stretching element 910 and the second stretching element 920 are arranged opposite to each other, and the U-shaped connection parts of the first stretching element 910 and the second stretching element 920 have overlapping parts; wherein, the two sides of the U-shaped connection portion of the second stretching element 920 are respectively provided with a through slot, and the U-shaped legs of the first stretching element 910 respectively penetrate into the through slots, which results in that the first stretching element 910 and the second stretching element 920 are partially overlapped. Similarly, a through slot may be provided in the first distracting element 910. The overlap is formed with a cavity 930 in which a resilient element 940, e.g. a spring or a rubber stud with elasticity, is arranged, the ends of which are connected to the first and second spreader elements 910, 920, respectively, e.g. glued or mechanically connected (e.g. riveted). The two U-shaped legs of the first spreader element 910 are each hinged with a rigid guide plate 950 having a guide bar opposite the other end of the hinged end; the outer side surfaces of the two U-shaped legs of the second stay element 920 are provided with guide grooves in the same extending direction as the U-shaped legs; the guide bar of the guide plate can slide in the guide groove. The U-shaped board leg tops of the first and second spreader members 910, 920 have notches, the first and second spreader members 910, 920 are respectively provided with an elastic bandage 60, and both ends of the elastic bandage are respectively disposed in the notches of the two leg tops of the aforementioned U-shaped board. Preferably, the elastic bandage may be made of a medical thermoplastic resin material. When the spine spinous process expanding device in the embodiment is installed, the two expanding elements are firstly extruded to enable the spinous processes of the corresponding bone segments to enter the U-shaped opening of the expanding elements, and then the expanding elements are released to enable the expanding elements to enter a natural state. Preferably, a limiting block is further arranged in the guide groove, the position of the limiting block in the guide groove is adjustable, and the limiting block can limit the sliding range of the guide rod, so that the limiting block can protect the elastic element in the cavity and cannot be damaged due to overlarge stretching. Since an elastic element is arranged between the two distracting elements, it allows a moderate variation of the distance between two adjacent condyles and is able to cushion this variation; at the same time, the spreading device can also allow slight dislocation between two adjacent bone segments (caused by human body twisting, for example), so the spine spinous process spreading device has good flexibility. Meanwhile, the spine spinous process is abutted against the elastic bandage, the elastic bandage can effectively buffer the action of the spine spinous process, abrasion of the spine spinous process can be prevented, and the spine spinous process is effectively protected.
When the elastic spine condyle connecting component is used, the spine spinous process expanding device is firstly installed, and then the facet joint interface filling device is installed. The elastic spine condyle connecting component provides elasticity and has better use effect and experience.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
