Description
Technical field
The utility model relates to a kind of bone screw, in particular to a kind of pelvis bone screw.
Background technique
People often requires to use bone plate and bone screw after pelvic fracture or bone split and fixes device fracture site, but mesh
The preceding bone screw used needs boring device first to carry out screw thread shading and opens up when bone screw is screwed into human body, after be screwed into again
Bone screw is screwed into after aperture again when in use, it may appear that the phenomenon that can not deeply tightening, it is poor to cause the healing of patient's pelvis.
Utility model content
The main purpose of the utility model is to provide a kind of pelvis bone screws, can effectively solve in background technique
The problem of.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of pelvis bone screw, including inner bolt, outer barrel nail, the inner bolt head of a nail, outer barrel follow closely end, internal thread
There is outer barrel to follow closely end, have internal thread fixing groove in the outer barrel nail end for fixing groove and block, the outer barrel nail
With interior hexagonal plum blossom counterbore, the interior hexagonal plum blossom counterbore is located at internal thread fixing groove periphery, in the outer barrel nail in socket
One end of screw, the inner bolt is equipped with the inner bolt head of a nail, and the inner bolt head of a nail is located in internal thread fixing groove, the outer spiral shell
Block is set in cylinder nail, and the inner bolt runs through block, and the outer barrel nail periphery is equipped with light bar segment and spiro rod section, the polished rod
Section is located between outer barrel nail end and spiro rod section.
Further, cross groove is dug on inner bolt head of a nail surface.
Further, the outer barrel nail end two sides are equipped with perforation, and connection steel wire is placed in the perforation.
Further, the inner bolt periphery has tapping screw thread.
Further, the inner bolt and outer barrel nail are that stainless steel material is made.
Compared with prior art, the utility model has the following beneficial effects: by setting by inner bolt, outer barrel nail,
Block, outer barrel nail end and the pelvis bone screw that is composed of the inner bolt head of a nail, so as to when in use, after aperture
It is screwed into again, to increase the fixation dynamics of bone screw, avoiding the occurrence of can not deeply tighten and cause showing for bone screw absent-mindedness
As to prevent discomfort caused by due to patient activity, being conducive to after mitigating osteopathy by hexagonal plum blossom counterbore in being arranged
Pain, by following closely end setting connection steel wire and perforation in outer barrel, so as to will quickly connect steel in the course of surgery
Silk is connected with bone screw, and clinical use is more convenient, shortens operating time, mitigates the pain during patients surgery
It is bitter.Therefore practicability is very high, is suitble to be widely popularized.
Detailed description of the invention

In figure: 1, inner bolt；2, spiro rod section；3, outer barrel nail；4, block；5, light bar segment；6, outer barrel follows closely end；7, even
Connect steel wire；8, the inner bolt head of a nail；9, it perforates；10, interior hexagonal plum blossom counterbore；11, internal thread fixing groove；12, cross groove；
13, tapping screw thread.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of pelvis bone screw, including inner bolt 1, outer barrel follow closely 3, the inner bolt head of a nail 8, outer spiral shell
There is outer barrel to follow closely end 6 for cylinder nail end 6, internal thread fixing groove 11 and block 4, the outer barrel nail 3, and the outer barrel follows closely end
There is internal thread fixing groove 11 and interior hexagonal plum blossom counterbore 10, the interior hexagonal plum blossom counterbore 10 is fixed positioned at internal thread in portion 6
11 periphery of slot, the outer barrel nail 3 is interior to be socketed inner bolt 1, and one end of the inner bolt 1 is equipped with the inner bolt head of a nail 8, the interior spiral shell
The nail head of a nail 8 is located in internal thread fixing groove 11, block 4 is arranged in the outer barrel nail 3, the inner bolt 1 runs through block 4, institute
State 3 periphery of outer barrel nail and be equipped with light bar segment 5 and spiro rod section 2, the light bar segment 5 be located at outer barrel nail end 6 and spiro rod section 2 it
Between.
Wherein, cross groove 12 is dug on 8 surface of the inner bolt head of a nail.Cross groove 12 can be convenient 1 feed of inner bolt
And withdrawing.
Wherein, outer barrel nail 6 two sides of end are equipped with perforation 9, and connection steel wire 7 is placed in the perforation 9.
Wherein, 1 periphery of inner bolt has tapping screw thread 13.
Wherein, the inner bolt 1 and outer barrel nail 3 are that stainless steel material is made.
It should be noted that the utility model is a kind of pelvis bone screw, and when work, medical staff's (surgical staff)
