The orthopedics kinesiology locking bone screw is suitable for orthopedic operations.
Description
Technical field
The present invention relates to the Orthopedic Clinical medical instruments field, refer to especially a kind of orthopaedics kinesiology locking bone screw.
Background technology
At present the structure of employed bone screw comprises screw body in bone surgery, and screw body is comprised of columniform nail section and the afterbody that is positioned at nail section tail end, and the outer surface of nail section is provided with elongated screw thread.
This bone screw is usually used in making bone again combination after fracture, bone screw needs to keep a period of time until bone is grown usually in human body after the operation, need certain healing space during bone growth, and traditional bone screw cortical layer and spongiosa osteoplaque of its screw thread and bone when implanting bone locks mutually, be difficult for loosening in inside bone, be unfavorable for the growth of bone, affect final healing effect.
Summary of the invention
Technical problem to be solved by this invention is: a kind of orthopaedics kinesiology locking bone screw is provided.
For addressing the above problem, the technical solution used in the present invention is: orthopaedics kinesiology locking bone screw, the screw head and the axostylus axostyle that comprise the integral type design, described axostylus axostyle comprises sliding part, spongiosa osseous part and cortex osseous part, sliding part is connected with screw head, the sliding part outer wall is smooth, the spongiosa osseous part is arranged on the sliding part front end and is connected with sliding part, its outer wall is provided with spongiosa osseous part screw thread, the cortex osseous part be arranged on spongiosa osseous part front end with and the spongiosa osseous part be connected, be provided with cortex osseous part screw thread on the cortex osseous part outer wall, spongiosa osseous part screw thread is consistent with the direction of cortex osseous part screw thread, and the pitch of spongiosa osseous part screw thread is 2～3 times of cortex osseous part screw thread.Described screw head is provided with interior hexagonal groove or blossom type groove.
The invention has the beneficial effects as follows: above-mentioned orthopaedics kinesiology locking bone screw, its axostylus axostyle is divided into sliding part, three parts of spongiosa osseous part and cortex osseous part, after bone screw is implanted bone, its cortex osseous part screw thread passes the spongiosa osteoplaque on bone top, cortical layer locks mutually with spongiosa osteoplaque and the cortical layer of bone cavity with the bottom, its spongiosa osseous part screw thread locks mutually with spongiosa osteoplaque and the cortical layer on bone top, the locking of cortex osseous part is the tightest, the locking pine of spongiosa osseous part is in the cortex osseous part, sliding part does not lock with bone, bone is locked extremely fully like this, is more conducive to the bone growth healing.

The specific embodiment
Below by specific embodiment orthopaedics kinesiology locking bone screw of the present invention is described in further detail.
As depicted in figs. 1 and 2, orthopaedics kinesiology locking bone screw, the screw head 1 and the axostylus axostyle 2 that comprise the integral type design, described axostylus axostyle 2 comprises sliding part 3, spongiosa osseous part 4 and cortex osseous part 5, sliding part 3 is connected with screw head 1, sliding part 3 outer walls are smooth, spongiosa osseous part 4 is arranged on sliding part 3 front ends and is connected with sliding part 3, its outer wall is provided with spongiosa osseous part screw thread 6, cortex osseous part 5 is arranged on spongiosa osseous part 4 front ends and is connected with spongiosa osseous part 4, be provided with cortex osseous part screw thread 7 on cortex osseous part 5 outer walls, spongiosa osseous part screw thread 6 is consistent with the direction of cortex osseous part screw thread 7, and the pitch of spongiosa osseous part screw thread 6 is 2～3 times of cortex osseous part screw thread 7.Described screw head 1 is provided with interior hexagonal groove 8.As shown in Figure 3, the groove 8 of screw head 1 also can be the shape that interior blossom type etc. matches with specific purpose tool, all belongs to protection category of the present invention.
As shown in Figure 4, in bone surgery, orthopaedics kinesiology locking bone screw matches with blade plate, be used for the fixedly bone of fracture, so that again combination of bone breaking part, bone screw is implanted bone and is locked, its cortex osseous part screw thread 7 passes the cortical layer 10 on bone top, spongiosa osteoplaque 9 locks with the spongiosa osteoplaque 9 that is positioned at the bottom and cortical layer 10 afterwards mutually with bone cavity 11, its spongiosa osseous part screw thread 6 locks mutually with cortical layer 10 and the spongiosa osteoplaque 9 on bone top, because cortex osseous part screw thread 7 pitch are the shortest, so 5 lockings of cortex osseous part are the tightest, and spongiosa osseous part screw thread 6 pitch are greater than cortex osseous part 5, so the locking pine of spongiosa osseous part 4 is in cortex osseous part 5, sliding part 3 outer walls are smooth, therefore sliding part 3 does not lock with bone, bone is by locking is dead fully like this, the spongiosa osseous part 4 of this bone screw and sliding part 3 can swing in bone when human motion, thereby for fracture brings the healing space, are more conducive to the bone growth healing.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
