Abstract
The invention discloses a kind of orthopaedics lock screw, including screw body, steel plate, guide cylinder, guide post, adjusting screw and head of screw, the guide cylinder is welded on screw body, and the guide post is parallel with screw body, and the adjusting screw is vertical with screw body.The characteristics of present invention has easy to operate, time saving and energy saving, safe and effective, is adapted to popularization and application.
Description
Technical field
The invention belongs to technical field of medical instruments, it is related to a kind of orthopaedics lock screw.
Background technology
The purpose of fracture surgical operation therapy is that, in order to rebuild dissection and recover function, Fracture internal fixaiion is to build on accurate fracture
Reset, the fixation of stabilization, and retain a kind of complex treatment on the basis of the early function sexuality of bone as far as possible.It is clinically frequent
Using screw internal fixation method, use locking steel plate so that bone combined with steel plate more firmly, the amputation allowed after resetting is more stable
A bit, but easy broken nail, and in specific operation process, position inaccurate, screw is not easy to import, to medical personnel
Operation bring certain difficulty, extend operating time, and certain pain is brought to patient, the body and mind to patient is good for
Health brings certain influence.
The content of the invention
It is an object of the invention to the defect for overcoming above-mentioned technology to exist, there is provided a kind of safely and effectively orthopaedics lock screw.
Its concrete technical scheme is：
A kind of orthopaedics lock screw, including screw body 1, steel plate 2, guide cylinder 3, guide post 4, adjusting screw 5 and screw
First 6, the guide cylinder 3 is welded on screw body 1, and the guide post 4 is parallel with screw body 1, the adjusting screw
5 is vertical with screw body 1.
Further, the head of screw 6 is provided with tapping screw thread.
Compared with prior art, beneficial effects of the present invention are：
Orthopaedics lock screw of the invention is provided with guide cylinder, guide post, facilitates the importing of screw, saves operating time, has safely
Effect, is adapted to popularization and application.
Brief description of the drawings
Fig. 1 is the schematic diagram of orthopaedics lock screw of the present invention.
Specific embodiment
Technical scheme is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
Reference picture 1, a kind of orthopaedics lock screw, including screw body 1, steel plate 2, guide cylinder 3, guide post 4, adjustable spiral shell
Bar 5 and head of screw 6, the guide cylinder 3 are welded on screw body 1, and the guide post 4 is parallel with screw body 1, institute
State adjusting screw 5 vertical with screw body 1.The head of screw 6 is provided with tapping screw thread.
Orthopaedics lock screw of the invention during concrete application, under the guiding of guide cylinder 3 and guide post 4, by adjustment
The depth of adjusting screw 5, determines the exact position of screw, by the importing of screw, completes operation.
The above, preferably specific embodiment only of the invention, protection scope of the present invention not limited to this are any to be familiar with
Those skilled in the art in the technical scope of present disclosure, the simple change of the technical scheme that can be become apparent to
Change or equivalence replacement is each fallen within protection scope of the present invention.
