Abstract

The invention relates to the technical field of medical instruments, in particular to a multi-start thread U-shaped nail. The multi-start thread U-shaped nail comprises a screw, threads, a cutting edge and a nail front end. The screw is provided with the threads which are multi-start threads, one end of the screw is provided with the cutting edge, and the other end of the screw is provided with the nail front end. The multi-start thread U-shaped nail is convenient to operate and firm in fracture fixation, wound union is fast, the single-start thread is changed into two-start or multi-start threads, the multi-start threads are long in lead and fast in rotation, operation time for patients is greatly shortened, operation pain of the patients is alleviated, and quite good effect is achieved.

Description

A kind of multiple thread staple
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of multiple thread staple.
Background technology
U-shaped pedicle nail is to be applied to spinal column important medical apparatus and instruments clinically, existing staple operation technique complexity, fracture fixation is firm not, make patient's wound healing slower, and existing staple mostly is one start screw structure, operation technique rotates very slow, can not save time for operation, reduces patient's misery.Therefore, design for overcoming the deficiency of above-mentioned technology the multiple thread design that meets body biomechanics, this design screws soon product in clinical use procedure; Can better play again effect that spinal column lifts; Pedicle nail is not easy the advantage of failure mode, alleviates a kind of multiple thread staple of patient's operation misery, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of multiple thread staple, it is simple in structure, according to the size of skeleton, conform to skeletal form, operation technique is easy, and fracture fixation is firm, and wound healing is fast, and employing multiple thread, screw soon, alleviate patient's operation misery, have extraordinary practical value.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multiple thread staple, comprise screw rod, screw thread, cutting edge, nail front end, on screw rod, be provided with screw thread, one end of screw rod is provided with cutting edge, the other end of screw rod is provided with nail front end, it is characterized in that: the screw thread on described screw rod is multiple thread.
The invention has the beneficial effects as follows:
1, operation technique of the present invention is easy, and fracture fixation is firm, and wound healing is fast;
2, the present invention changes traditional one start screw into double end or multiple thread, and multiple thread helical pitch is long, and spill spin block has shortened the time that patient performs the operation greatly, has alleviated patient's operation misery, has extraordinary effect;
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Fig. 3 is that the present invention looks up structural representation.
Fig. 4 is the right TV structure schematic diagram of the present invention.
Fig. 5 is the local enlarged diagram of A part in Fig. 2 of the present invention.
Description of reference numerals: 1-screw rod; 2-screw thread; 3-cutting edge; 4-follows closely front end.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention, should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1-5 are a kind of multiple thread staple of the present invention structural representation, comprise screw rod 1, screw thread 2, cutting edge 3, nail front end 4, on screw rod 1, be provided with screw thread 2, one end of screw rod 1 is provided with cutting edge 3, the other end of screw rod 1 is provided with nail front end 4, it is characterized in that: the screw thread 2 on described screw rod 1 is multiple thread, operation technique of the present invention is easy, fracture fixation is firm, wound healing is fast, the present invention changes traditional one start screw into double end or multiple thread, multiple thread helical pitch is long, spill spin block, greatly shorten the time of patient's operation, alleviate patient's operation misery, there is extraordinary effect.
