the central weight-reducing body 31 comprises a plurality of weight-reducing units 32, the outer outline of the weight-reducing units 32 is in a cube shape as a whole, the weight-reducing units 32 are provided with spherical weight-reducing cavities 33, the diameter of each spherical weight-reducing cavity 33 is larger than the width of each weight-reducing unit 32, weight-reducing round holes 34 are formed through the side wall of each weight-reducing unit 32, the weight-reducing units 32 are tightly spliced with each other, the weight-reducing round holes 34 of the adjacent weight-reducing units 32 are mutually communicated, and the diameter of each spherical weight-reducing cavity 33 is larger than the diameter of each spherical bone growth cavity 23.
The bone can grow into the spherical bone growth cavity 23 in the bone growth unit 22 in the growth process, and the bone in the spherical bone growth cavity 23 can grow and increase, so that the bone in the spherical bone growth cavity 23 and the width are larger than the bone growth round hole 24, the bone is clamped with the inner wall of the bone growth unit 22, and the bone is stably attached to the bone growth layer 21.
The bone in-growth layer 21 is closely spliced with 4 layers of bone in-growth units 22 in the thickness direction. The 4-layer bone in-growth unit 22 can improve the structural strength of the bone in-growth layer 21, and bones can pass through the 4-layer bone in-growth unit 22 through the adjacent bone in-growth round holes 24, so that the bones and the bone in-growth layer 21 have better attaching effect, and the structural strength of the bone in-growth layer 21 can be further improved.
Bone ingrowth layers 21 are provided at three different sides of the outer support frame 11.
The outer supporting frame 11 is fixedly connected with a connecting sleeve 14, and the connecting sleeve 14 penetrates through the interior of the central weight-reducing body 31. Screws for connecting the bone may be passed through the connection sleeve 14 to effect a secure mounting of the sacral prosthesis to the bone. The connecting sleeve 14 can provide support to the outer support frame 11 and the central weight-reducing body 31 to further increase the overall structural strength of the sacral prosthesis.
The connecting sleeves 14 are provided with 3 connecting sleeves 14, the 3 connecting sleeves 14 are parallel to each other and have coplanar axes, a reinforcing rod 15 is arranged between the adjacent connecting sleeves 14, and two ends of the reinforcing rod 15 are respectively fixedly connected with the two adjacent connecting sleeves 14. The overall structural strength of the sacral prosthesis is further enhanced by the 3 connection sleeves 14.
The support rod 12 fixedly connected to the bone in-growth layer 21 is provided with a width extension 13, and the width extension 13 extends in the thickness direction of the support rod 12.
The arrangement direction of the plurality of bone in-growth units 22 is the same as the arrangement direction of the plurality of weight-reduction units 32. The load transmission direction of the weight-reduction unit 32 is made the same as the load transmission direction of the bone in-growth unit 22, thereby improving the structural stability between the bone in-growth unit 22 and the weight-reduction unit 32.
This embodiment has the following advantages:
the outer support frame 11 can be in direct contact with the bone, bearing most of the load experienced by the entire sacral prosthesis. The bone ingrowth layer 21 is in direct contact with the bone for ingrowth of bone and attachment to the bone ingrowth layer 21. The central weight-reducing body 31 fills the gap in the outer support frame 11, can bear a part of the load received by the sacral prosthesis, can provide stable support for the bone in-growth layer 21, serves to improve the overall structural stability of the outer support frame 11, the bone in-growth layer 21 and the central weight-reducing body 31, and can maintain a stable connection of the bone in-growth layer 21 and the bone.
Since bone can grow in the spherical bone ingrowth cavity 23 to form a mass having a width greater than the bone ingrowth round hole 24, the sacral prosthesis can achieve better bone attachment by the bone mass located in the spherical bone ingrowth cavity 23 than by providing a protrusion on the surface of the prosthesis or providing the surface of the prosthesis with a spherical surface. And each bone growth unit 22 is mutually communicated through the adjacent bone growth round holes 24, so that bones can grow into the adjacent spherical bone growth cavity 23 through the adjacent bone growth round holes 24 after growing into the spherical bone growth cavity 23, bones in different spherical bone growth cavities 23 can be mutually connected, the attaching effect of the bones is further improved, and meanwhile, the interconnected bones can also provide stable support for the bone growth layer 21, so that the structural strength of the bone growth layer 21 can be effectively improved. And because the bone in-growth layer 21 is provided with a plurality of bone in-growth units 22 with spherical bone in-growth cavities 23, the weight of the bone in-growth layer 21 can be greatly reduced, so that the effect of reducing the weight of the prosthesis while improving the structural strength is achieved, and the comfort level is further improved.
The inner surface of the bone in-growth unit 22 is an arc with a diameter of 250 micrometers, so that the bone in-growth cavity 23 can form a wide enough body, and the bone in-growth layer 21 can form proper porosity, thereby ensuring the attachment effect of the bone and the structural stability of the bone in-growth layer 21.
By providing the spherical weight-reducing cavity 33 in the weight-reducing unit 32, the mass of the weight-reducing unit 32 is effectively reduced. At the same time, the central weight-reducing body 31 can also provide a more reliable supporting force for the outer supporting frame 11 and the bone in-growth layer 21, and the overall weight is greatly reduced while the structural strength is ensured. The closely spliced plurality of weight-reduction units 32 and the plurality of bone in-growth units 22 can more stably bear load, thereby improving structural strength. The weight-reduction unit 32 approximates the overall shape of the bone ingrowth unit 22, facilitating product sizing and production, and is particularly well suited for tailoring a personalized sacral prosthesis for ease of use.
By the bone ingrowth layer 21 at three different sides of the outer support frame 11, the contact surface of the bone and the bone ingrowth layer 21 is increased, and the attachment effect of the bone is improved. Forces exerted on the sacral prosthesis from three different sides can cancel each other out, further improving the structural stability of the sacral prosthesis.
Since the connecting sleeve 14 penetrates through the interior of the central weight-reducing body 31, the reinforcing rod 15 fixed with the connecting sleeve 14 is also positioned in the interior of the central connecting sleeve 14, and the structural strength of the connecting sleeve 14 is improved through the reinforcing rod 15, and meanwhile, the structural strength of the central weight-reducing body 31 is also improved through the reinforcing rod 15, so that the overall structural strength of the sacral prosthesis is further improved.
Since the support rod 12 connected to the bone in-growth layer 21 is required to provide a supporting force to the bone in-growth layer 21, the width extension section 13 is provided on the support rod 12 connected to the bone in-growth layer 21, and the structural strength of the support rod 12 connected to the bone in-growth layer 21 is improved by the width extension section 13, so that the structural strength of the whole sacrum can be more effectively improved by the extension section with smaller weight.
In view of the above, after reading the present document, those skilled in the art should make various other corresponding changes without creative mental effort according to the technical scheme and the technical conception of the present invention, which are all within the scope of the present invention.
