Abstract
The invention discloses a novel locking steel plate screw fixing system which comprises an independent screw tail and a screw rod. The independent screw tail is cylindrical, a thread is arranged at one end of the inner wall of the independent screw tail and is matched and connected with a thread on the outer side of the tail of the screw rod, the inner wall of the other end of the independent screw tail is set into a hexagon or quincunx, a thread is arranged on the outer side of the independent screw tail and is matched with an orthopedic locking steel plate threaded hole, and an inner hexagon groove or quincunx groove is arranged at the connecting end of the screw rod and the independent screw tail. The novel locking steel plate screw fixing system effectively solves the problem that a locking screw is difficultly taken out of a bone and a locking steel plate due to deformation of the locking screw.
Description
Technical field
The present invention relates to a kind ofly for the orthopedic implant field, specifically, relate to a kind of lock screw for locking steel plate fixed system fixing in the orthopaedics.
Background technology
At present, orthopaedics implant into body lock screw usually causes taking out difficulty because of distortion, even forms the secondary fracture, and now also without the feasible method head it off.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of locked steel plate screw fixing system, and this design can solve the implant into body lock screw and take out hard problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of locked steel plate screw is fixed, comprise an independent nail tail and a nail bar, described independent nail tail is tubular, its inwall one end is provided with screw thread and is complementary with the outside screw of nail bar afterbody and is connected, other end inwall is provided with and is hexagon or quincunx, and the independent nail tail outside is provided with screw thread and orthopaedics locking steel plate screwed hole is complementary, and described nail bar is provided with interior hex slot or Flos Mume groove with independent nail tail link.
The present invention seeks to solve the lock screw distortion and cause taking out hard problem from bone and locking steel plate, provide a kind of effective means by the design.
Description of drawings
Below in conjunction with the drawings and specific embodiments invention is described further.
Fig. 1 is fixedly cross-sectional view of a kind of locked steel plate screw of the present invention.
The specific embodiment
As shown in Figure 1, a kind of locked steel plate screw of the present invention is fixed, comprise an independent nail tail 1 and a nail bar 2, described independent nail tail 1 is tubular, its inwall one end is provided with screw thread and is complementary with the outside screw of nail bar 2 afterbodys and is connected, other end inwall is provided with and is hexagon or quincunx, and independent nail tail 1 outside is provided with screw thread and orthopaedics locking steel plate 3 screwed holes are complementary, and described nail bar 1 is provided with interior hex slot or Flos Mume groove with independent nail tail 2 links.
The fixing operation principle of a kind of locked steel plate screw of the present invention is: will follow closely bar 2 and be screwed into the independent tail 1 of following closely, its complex is screwed in the osseous tissue through steel plate screw thread 3 holes, and follow closely simultaneously in the screwed hole that tail 1 is screwed into locking steel plate 3.When dismounting, in the hexagon by independent nail tail 1 or the quincunx hole it is back-outed first, take out again steel plate 3, the interior hex slot by nail bar 2 or Flos Mume groove are with its osseous tissue of back-outing.
Claims (3)
1. a locked steel plate screw is fixed, and it is characterized in that: described lock screw comprises an independent nail tail 1 and a nail bar 2.
2. according to claim 1, it is characterized in that: described independent nail tail 1 is tubular, inwall one end is provided with screw thread and nail bar 2 one sections outside screw and is complementary and is connected, and the inwall other end is made as hexagon or quincunx, independently follows closely that tail 1 outside is provided with screw thread and locking steel plate screw thread 3 holes are complementary.
3. it is characterized in that according to claim 1: described nail bar 2 is provided with interior hex slot or Flos Mume groove with independent nail tail 1 link.
