Abstract
The utility model relates to a hollow compression screw special for a patella fracture. The hollow compression screw special for the patella fracture comprises a hollow cylindrical groove, threads, a hollow compression screw body, circular hexagonal sockets, screws and nuts. The nuts are arranged on the two sides of the hollow compression screw body. The two sides of the hollow compression screw body are provided with the threads. The two sides of the hollow compression screw body are arranged to be the circular hexagonal sockets. The two sides of the hollow compression screw body are provided with the threads. The hollow cylindrical groove is formed inside the hollow compression screw body. The threads are arranged inside the hollow cylindrical groove. The threads are arranged at the screws. The nuts are arranged to be the circular hexagonal sockets. According to the hollow compression screw special for the patella fracture, the nuts on the two sides are used for fixing the hollow compression screw body, and patella crack engagement is more stable, so that the treatment effect of the patella fracture is remarkably improved. The hollow compression screw special for the patella fracture is simple in structure and convenient to operate, the clinical medical level is greatly improved, patient recovery is facilitated, and a gap of lacking a screw device for being fixedly connected with a patella in the prior art is filled.
Description
Technical field
This utility model belongs to medical auxiliary apparatus technical field, relates in particular to a kind of Patella fracture special hollow forcing screw.
Background technology
At present, Patella fracture is a kind of common intra-articular fracture in orthopaedic trauma, and accounting for fracture is 0.5--1.5%.The operation method of Patella fracture is various, although open reduction tension band wiring internal fixation is as a kind of operation of classics, but easily occur steel wire slippage, steel wire to be difficult to tighten and cause that Kirschner wire skids off, skin irritation pain, sometimes needing again to perform the operation, the problem such as operation in advance.Therefore, need a kind of screw device that can be fixedly connected with patella badly.
Utility model content
This utility model provides a kind of simple in structure, easy to install, Patella fracture special hollow forcing screw of increasing work efficiency for solving the existing problem that lacks to be fixedly connected with patella screw device.
The technical scheme that this utility model is taked for the technical problem existing in solution known technology is:
The Patella fracture special hollow forcing screw of this utility model embodiment, this Patella fracture special hollow forcing screw comprises: hollow cylinder groove, screw thread, hollow forcing screw, circular interior hexagonal, screw, nut;
Nut is arranged in hollow forcing screw both sides, hollow forcing screw both sides are provided with screw thread, hollow forcing screw both sides are set to circular interior hexagonal, the both sides of hollow forcing screw arrange screw thread, hollow forcing screw inside is hollow cylinder groove, in hollow cylinder groove, screw thread is set, screw place arranges screw thread, and nut is set to circular interior hexagonal.
This utility model can also adopt following technical measures:
In this utility model embodiment, outer dia be set be 2.0,2.4,2.7mm hollow, inside diameter is 1.0, the hollow forcing screw of 2.0mm.
Further, arrange that two diameters are 1.0, the nut of 2.0mm.
Further, adopt the hollow forcing screw of metal material.
Further, adopt the nut of metal material.
Further, nut is set to circular interior hexagonal.
Advantage and the good effect that the utlity model has are: because this utility model is by both sides nut fixation hollow forcing screw, the engagement of patella crack is more firm, and the therapeutic effect of Patella fracture is significantly improved.Of the present utility model simple in structure, easy to operate, improve greatly clinical medical level, be conducive to patient's rehabilitation, make up the existing blank that lacks to be fixedly connected with patella screw device.
Brief description of the drawings
Fig. 1 is the structural representation of the Patella fracture special hollow forcing screw that provides of this utility model embodiment;
Fig. 2 is the structural representation of the nut that provides of this utility model embodiment;
In figure: 1, hollow cylinder groove; 2, screw thread; 3, hollow forcing screw; 4, circular interior hexagonal; 5, screw; 6, nut.
Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows: this utility model does not exist the innovation of software or method.
Refer to Fig. 1 and Fig. 2:
As depicted in figs. 1 and 2, the Patella fracture special hollow forcing screw of this utility model embodiment mainly by: hollow cylinder groove 1, screw thread 2, hollow forcing screw 3, circular in hexagonal 4, screw 5, nut 6 form;
Nut 6 is arranged in hollow forcing screw 3 both sides, hollow forcing screw 3 both sides are provided with screw thread 2, hollow forcing screw 3 both sides are set to circular interior hexagonal 4, the both sides of hollow forcing screw 3 arrange screw thread 2, hollow forcing screw inside is hollow cylinder groove 1, the interior screw thread 2 that arranges of hollow cylinder groove 1, screw 5 places arrange screw thread 2, and nut 6 is set to circular interior hexagonal 4.
In embodiment of the present utility model, this utility model by outer dia be 2.0,2.4,2.7mm hollow inside diameter is 1.0, the hollow forcing screw of 2.0mm 3, two diameters are 1.0,2.0mm nut 6 forms; Described nut 6 is arranged in described hollow forcing screw 3 both sides, and hollow forcing screw 3 adopts metal material to make, and its both sides are with screw thread 2, hollow forcing screw 3 both sides are set to interior hexagonal, both sides arrange screw thread 2, and inside is hollow cylinder groove 1, and screw thread 2 is set in groove; Nut 6 adopts metal material to make, and screw 5 places arrange screw thread 2, and nut 6 is set to circular interior hexagonal 4.
Compared with existing patella treatment technology, the beneficial effects of the utility model are:
This nail diameter is little, is suitable for less Patella fracture piece; There is screw thread at two ends, and intermedium screw thread, plays pressurization; Two ends nut plays the effect that prevents tension band slippage; Simple in structure, be easy to produce.
The above is only to preferred embodiment of the present utility model, not this utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
