Abstract
The utility model relates to an orthopaedics internal fixation bolt, comprising a screw and a nut, the thread section of the screw is provided with a plurality of ring grooves which have a certain interval with each other. The orthopaedics internal fixation bolt has advantages of easy operation, short surgical trauma time.
Description
This utility model relates to orthopaedics internal fixation bolt.
At present, the used bolt of orthopaedics is made up of screw rod and nut.The length of required screw rod often is difficult for accurately measuring, and in the actual operation, often selects long screw rod for use, behind the fastening nut, measures required screw rod physical length, cuts the part that grows again, the nut of screwing at last.Because of when cutting the screw rod that grows, destroyed the screw thread on the screw rod, cause and screw on or difficulty very when backing out nut, increased operating difficulty, prolonged the time of operation wound.
The purpose of this utility model is to provide a kind of easy and simple to handle, orthopaedics internal fixation bolt that the operation wound time is short.
A kind of orthopaedics internal fixation bolt comprises screw rod and nut, is provided with the annular groove of several spaces in above-mentioned screw flight section.
Above-mentioned bolt, above-mentioned screw rod and nut can be screwed pipe and adjust screw, are provided with a round platform at above-mentioned adjustment screw head.
Above-mentioned bolt comprises that one measures guide post, and above-mentioned measurement guide post surface is provided with scale, measures guide post one end and is provided with the external screw thread that matches with the screwed pipe female thread, measures another termination of guide post and is provided with nest.
Because of screw flight of the present utility model is provided with annular groove, behind the fastening nut, the part that can will grow is used the pliers switch out easily, saved the operation of backing out the nut of screwing on again, and do not destroy screw thread, be convenient to back out nut and unload screw rod, saved the operation wound time.Screw rod is by screwed pipe and adjust the screw replacement, and directly precession or back-out are adjusted screw and regulated length, then can further improve work efficiency, simplify working process.If set up the measurement guide post, then more can further improve work efficiency, reduce the operation wound time.The utlity model has simple in structure, the low and advantage being convenient to promote of cost.
Below in conjunction with accompanying drawing this utility model is described in detail.
Fig. 1 is the structural representation of embodiment 1 screw rod.
Fig. 2 is the structural representation of embodiment 2.
Fig. 3 is the structural representation that embodiment 3 measures guide post.
With reference to Fig. 1, embodiment 1 comprises screw rod 1 and nut, is provided with the annular groove 3 of several spaces in above-mentioned screw flight section 2.
With reference to Fig. 2, embodiment 2 comprises screwed pipe 4 and adjusts screw 5, is provided with a round platform 6 at above-mentioned adjustment screw head.
With reference to Fig. 3, embodiment 3 difference from Example 2 are to comprise that one measures guide post 8, and above-mentioned measurement guide post surface is provided with scale, measures guide post one end and is provided with the external screw thread 7 that matches with the screwed pipe female thread, measures another termination of guide post and is provided with nest 9.
