The handle 21 of the detachable component 2 is used for holding, the rod 22 can provide a service length and facilitate the draw hook 23 to extend into the operation hole 12, and the operation hole 12 adopts a hole structure matched with the rod 22, so that the detachable component is convenient to detach.
In one embodiment, the operation hole 12 has a lower hole 122 and an upper hole 121 with a smaller diameter than the lower hole 122, the upper hole 121 and the lower hole 122 are mutually communicated, and an access notch 123 vertically penetrating and communicating with the lower hole 122 is formed at one side of the upper hole 121; the diameter of the upper hole 121 is equal to or larger than the diameter of the rod 22, and the width of the access notch 123 is equal to or larger than the width of the draw hook 23.
In this way, the multifunctional filler needs to be matched with the dismounting component 2 for mounting and dismounting, specifically, the rod portion 22 of the dismounting component 2 can penetrate into the operation hole 12 of the multifunctional filler, so that the multifunctional filler can be brought into the bone hole, and conversely, the multifunctional filler can be hooked out of the bone hole in a practical and convenient manner by only enabling the draw hook 23 of the rod portion 22 of the dismounting component 2 to correspondingly penetrate through the access notch 123 during dismounting and then rotating the dismounting component 2.
Preferred embodiment 1:
referring to fig. 1 and 2, a multifunctional biologic filler includes an alloy substrate 11 having a shape suitable for filling bone holes, a titanium alloy coating coated on the surface of the alloy substrate 11, a porous net structure formed on the surface of the substrate by the titanium alloy coating, and a hydroxyapatite layer on the titanium alloy coating.
The alloy matrix 11 is made of CoCrMo material.
The alloy base 11 is cylindrical.
An end face of the alloy substrate 11 is provided with an operation hole 12 for mounting and/or dismounting.
The multifunctional biological filler 1 is fixed in the bone hole through bone cement.
The two ends of the multifunctional biological filler 1 are provided with chamfer structures 13.
The implementation principle is as follows: compared with the traditional bone cement filling technology, the bone cement filling device can fill holes more conveniently, can better ensure bone length, and can prevent the occurrence of fracture risk due to the influence of excessive driving of nail holes and the stress of bones. Furthermore, the multifunctional biological filler 1 has better biocompatibility, has no side effect of bone cement use, and can avoid side effect of patients allergic to bone cement materials when used together with biological prostheses. Meanwhile, the device is convenient to install and detach.
Preferred example 2:
referring to fig. 1-3, a biologic filler kit includes a detachable component 2 and a multifunctional filler according to the above preferred embodiment 1; the dismounting component 2 is provided with a handle part 21 and a rod part 22 which are sequentially connected, a drag hook 23 is arranged at the end of the rod part 22, and the drag hook 23 is perpendicular to the rod part 22; an operation hole 12 is arranged on one end face of the multifunctional filler, and the operation hole 12 is matched with one end of a rod portion 22 provided with a draw hook 23.
The operation hole 12 has a lower hole 122 and an upper hole 121 with a smaller diameter than the lower hole 122, the upper hole 121 and the lower hole 122 are communicated with each other, and an access notch 123 vertically penetrating through and communicating with the lower hole 122 is formed at one side of the upper hole 121; the diameter of the upper hole 121 is equal to or larger than the diameter of the rod 22, and the width of the access notch 123 is equal to or larger than the width of the draw hook 23.
The implementation principle is as follows: when the multifunctional biological filler 1 is installed, the multifunctional biological filler 1 is connected with the pin joint through the pin hole and is forced to push into the hole, and when the hole needs to be repaired in an operation, the installed biological filler can be penetrated into the hole by the drag hook 23, and the biological filler is pulled out, so that the multifunctional biological filler is convenient and quick.
Finally, it should be noted that: the foregoing description is only of the preferred embodiments of the invention and is not intended to limit the scope of the invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
