Abstract
The invention discloses an expansion bone nail, which comprises a bone nail body and an operating cap; an expansion screw rod is arranged inside the bone nail body, and the operating cap is in threaded connection to the expansion screw rod; the expansion bone nail is characterized in that the bone nail body includes a first bone nail body and a second bone nail body; screw threads are arranged on the sidewalls of the interiors of the first bone nail body and the second bone nail body in a parallel mode; the expansion screw rod is in threaded connection to the bone nail body; and the first bone nail body and the second bone nail body are combined by virtue of the expansion screw rod, so that a structure with round cross section is formed. The expansion bone nail provided by the invention, which includes the first bone nail body and the second bone nail body, can further improve medical health standard, and the first bone nail body and the second bone nail body are assembled when an operation is required, so as to facilitate combination; and by setting a fixed sleeve which is in fixed connection to the bone nail body and is in threaded connection to the expansion screw rod, expansion force can be controlled during expanding, so as to precisely control operation progress conveniently.
Description
Technical field
The present invention relates to field of medical appliances, especially relate to a kind of expansion bone nail.
Background technology
Nail is skeletal fixation device conventional in bone surgery, and nail can be fixed on skeleton the device such as connecting plate, fixing head, conveniently treats the orthopaedic diseases such as fracture, textured bone.
Existing nail easily produces and loosens in osseous tissue, not easily fixing in osseous tissue, and loosen carry out retightening while can cause osseous tissue secondary insult.Carrying out, in the fixing operation of osseous tissue, needing osseous tissue to be carried out disinfection, seals up for safekeeping, be inconvenient to operate, and easily cause sterilization and clean incomplete, do not meet medical sanitary safety.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of expansion bone nail.
Object of the present invention will be achieved by the following technical programs: first aspect, a kind of expansion bone nail, comprise: nail body and operation cap, dilating screw is provided with in described nail body inside, described operation cap is threaded with described dilating screw, it is characterized in that, described nail body comprises the first nail body and the second nail body, what described first nail body was parallel with the internal side wall of described second nail body is provided with screw thread, described dilating screw is threaded with described nail body, after described first nail body and described second nail body are combined by dilating screw, cross section is circular.
In conjunction with first aspect, in the implementation that the first is possible, described screw thread comprises the first screw thread and the second screw thread, and described first screw thread and described second screw thread interval are arranged and the pitch of described first screw thread is greater than the pitch of described second screw thread.
In conjunction with first aspect, in the implementation that the second is possible, be provided with fixed cover between described operation cap and described dilating screw, described fixed cover can be fixedly connected with described nail body.
In conjunction with the implementation that the second of first aspect is possible, in the implementation that the third is possible, the internal side wall of described fixed cover is provided with the 3rd screw thread, and described 3rd screw thread is threaded with described dilating screw.
In conjunction with the first possible implementation of first aspect, in the 4th kind of possible implementation, described first nail body and described second nail body comprise threaded joints and bulge respectively, and the cross section that the diameter of section of described bulge is less than described threaded joints is direct.
Outstanding effect of the present invention is: by nail body being divided into the first nail body and the second nail body, can separately carry out sealing up for safekeeping and sterilizing no time, improves medical sanitary requirement further, assembles when needs use operation, convenient combination; By arranging fixed cover between operation cap and dilating screw, fixed cover is fixedly connected with nail body, is threaded between dilating screw with fixed cover, can control the dynamics expanded when expanding, and is convenient to the progress accurately controlling operation.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of swell fixture provided by the invention.
Detailed description of the invention
As shown in Figure 1, embodiments provide a kind of expansion bone nail, comprising: nail body 1 and operation cap 2, be provided with dilating screw 3 in nail body 1 inside, and operation cap 2 is threaded with dilating screw 3.Wherein, swell fixture 3, after determining with operation cap 2 screw thread fixed, can rotate with operation cap 2 simultaneously.Be provided with fixed cover 4 between operation cap 2 and dilating screw 3, fixed cover 4 can be fixedly connected with nail body 1, and the internal side wall of fixed cover 4 is provided with the 3rd screw thread, and the 3rd screw thread is threaded with dilating screw 3.After combining, rotating operation cap 2 can drive dilating screw 3 to rotate, and fixed cover 4 can play the effect guiding and accurately control simultaneously.
Nail body 1 comprises the first nail body 11 and the second nail body 12, what the first nail body 11 was parallel with the internal side wall of the second nail body 12 is provided with screw thread, first nail body 11 and the second nail body 12 comprise threaded joints 13 and bulge 14 respectively, and the cross section that the diameter of section of bulge 14 is less than threaded joints 13 is direct.For preventing dilating screw 3 in threaded joints 13, by the rotation of dilating screw 3, bulge 14 is expanded.Dilating screw 3 is threaded with nail body 1, and the first nail body 11 and the second nail body 12 combine rear cross section for circular by dilating screw 3.Wherein, screw thread comprises the first screw thread and the second screw thread, and the first screw thread and the second screw thread interval are arranged and the pitch of the first screw thread is greater than the pitch of the second screw thread.By arranging the first screw thread and second screw thread of different pitch, better compatible degree can be had when adjustment first nail body 11 and the second nail body 12.
The invention provides a kind of swell fixture, by nail body 1 being divided into the first nail body 11 and the second nail body 12, can separately carry out sealing up for safekeeping and sterilizing no time, improving medical sanitary requirement further, assemble when needs use operation, convenient combination; By arranging fixed cover 4 between operation cap 2 and dilating screw 3, fixed cover 4 is fixedly connected with nail body 1, is threaded between dilating screw 3 with fixed cover 4, can control the dynamics expanded when expanding, and is convenient to the progress accurately controlling operation.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
