Abstract
The utility model discloses a novel locking plate bolt fixing device, comprising an independent bolt tail and a bolt rod, wherein the independent bolt tail is cylindrical, one end of the inner wall is provided with a screw matched and connected with an outer side screw of the tail part of the bolt rod, the inner wall of the other end is configured into hexagonal, the outer side of the independent bolt tail is provided with a screw matched with a screw hole of an orthopedic locking plate, the end of the bolt rod connected with the independent bolt tail is provided with an inner hexagon slot or a plum slot. The utility model aims to solving the problem that assistant bone and locking plate are difficult to be taken out caused by deformation of locking bolt, and providing an effective means with the adoption of the above design.
Description
Technical field
This utility model relates to a kind of orthopaedics implants field that is used for, and specifically, relates to a kind of lock screw that is used for the locking steel plate fixed system of orthopaedics internal fixation.
Background technology
At present, orthopaedics implant into body lock screw usually causes taking out difficulty because of distortion, even forms the secondary fracture, and does not also have the feasible method head it off now.
The utility model content
The technical problem that this utility model will solve is to provide a kind of novel locking steel plate screw fixing system, and this design can solve the implant into body lock screw and take out difficult problem.
In order to solve the problems of the technologies described above; This utility model adopts following technical scheme: a kind of novel locking steel plate screw fixture, comprise an independent nail tail and a nail bar, and said independent nail tail is a 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, and the independent nail tail outside is provided with screw thread and orthopaedics locking steel plate screwed hole is complementary, hex slot or Flos Mume groove in said nail bar is provided with independent nail tail link.
This utility model purpose is to solve the lock screw distortion to cause taking out difficult problem from bone and locking steel plate, through the design a kind of effective means is provided.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment utility model is described further.
Fig. 1 is a kind of novel locking steel plate screw fixture cross-sectional view of this utility model.
The specific embodiment
As shown in Figure 1; A kind of novel locking steel plate screw fixture of this utility model comprises an independent nail tail 1 and a nail bar 2, and said independent nail tail 1 is a 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, hex slot or Flos Mume groove in said nail bar 2 is provided with independent nail tail 1 link.
The operation principle of a kind of novel locking steel plate screw fixture of this utility model is: will follow closely bar 2 and be screwed into independent nail tail 1, its complex is screwed in the osseous tissue through steel plate 3 screwed holes, independent simultaneously nail tail 1 is screwed in the screwed hole of locking steel plate 3.When dismounting, in hexagon through independent nail tail 1 or the quincunx hole it is back-outed earlier, take out steel plate 3 again, interior hex slot through nail bar 2 or Flos Mume groove are with its osseous tissue of back-outing.
