Description
Technical field
The present invention relates to a kind of screw, and in particular to a kind of orthopaedics lock screw, belongs to technical field of medical equipment.
Background technology
Locking steel plate screw system is the most-often used bone fracture internal fixing device of current orthopaedics, can effectively be prevented
The loosening of screw, extract and the complication such as fracture, but report in recent years thinks that locking steel plate screw system can be limited
The activity of fracture site processed, produces atrophic type bone nonunion, has at a relatively high nonunion rate, generally require needs
Perform the operation again, not only to patient physiology and it is psychological cause burden, and also bring heavy warp to family
Ji burden, therefore, it is proposed that a kind of orthopaedics lock screw.
The content of the invention
The technical problem to be solved in the present invention overcomes existing defect, and there is provided a kind of orthopaedics lock screw, the orthopaedics
Lock screw, global design rationally, promotes the generation of poroma, the disunion rate of fracture is reduced, with very
Good clinical value, the problem of effectively can solving in background technology.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
The present invention provides a kind of orthopaedics lock screw, including shank of screw, threaded hole, head of screw, external screw thread, spiral shell
Follow closely and head of screw is provided with the top of tail, internal thread, steel plate, pin-and-hole and pin-and-hole screw thread, the shank of screw and is arranged on
Threaded hole on head of screw, the shank of screw is provided with internal thread and the external screw thread being arranged on internal thread, institute
The pin-and-hole screw thread that pin-and-hole is provided with steel plate and is arranged on the inside of pin-and-hole is stated, the shank of screw bottom is provided with spiral shell
Follow closely tail.
As a preferred technical solution of the present invention, the external screw thread can be according to pin-and-hole with the minor diameter of internal thread
Internal diameter and set.
As a preferred technical solution of the present invention, the pin-and-hole is specially multigroup.
The beneficial effect that is reached of the present invention is：This kind of orthopaedics lock screw, with a relatively high therapeutic effect,
The pain of patient is alleviated, treatment time is shortened, meanwhile, with good promotion effect.

It is specially multigroup, with a relatively high therapeutic effect, the pain of patient is alleviated, treatment time is shortened, together
When, with good promotion effect, the orthopaedics lock screw, global design rationally, promotes the generation of poroma,
The disunion rate of fracture is reduced, with good clinical value.
It should be noted that the present invention for a kind of orthopaedics lock screw in use, steel plate 7 is stuck in by orthopedist
Fracture, inserts pin-and-hole 8, with external screw thread 4 and pin by the threaded hole 2 on head of screw 3 by shank of screw 1
The dislocation of hole screw thread 9 combines steel plate 7 being fixed on fracture.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, this is not limited to
Invention, although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part
Technical characteristic carries out equivalent.Within the spirit and principles of the invention, it is any modification for being made, equivalent
Replace, improve etc., it should be included within the scope of the present invention.
