Often pain and the region of generation friction.
When by operation hallux valgus is carried out orthopedic time, need to block first metatarsal cervical region, carry out orthopedic after again
Secondary take back；But prior art does not carry out aid during osteotomy, frequently results in cutout, inconvenience
Again take back in first metatarsal.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of first metatarsal cervical region osteotomy location
Device.
The first metatarsal cervical region bone cutting positioner that this utility model provides ,-include the first positioning body and the second positioning body；
Wherein, described first positioning body removably connects with described second positioning body；The one end of described first positioning body with
The one end of described second positioning body forms saw blade guide slit relatively；
Described first positioning body and described second positioning body are provided with multiple fixing pin.
Preferably, described first positioning body is provided with dovetail groove；
The other end of described second positioning body is provided with the installed part matched with described dovetail groove；Described installed part is arranged on

Preferably, milled screw is also included；
Wherein, it is provided with the first screwed hole in described dovetail groove；The other end of described second positioning body be provided through
Two screwed holes；
Threaded described second screwed hole of described milled screw, the first screwed hole, thus formed described first positioning body with
Described second positioning body removably connects.
Preferably, the V-shaped projection of one end of described first positioning body；The one end of described second positioning body is V-shaped recessed
Groove；
Described V-arrangement is protruding and the described relative saw blade guide slit forming V-arrangement of v-depression.
Preferably, form saw blade between described first positioning body and described second positioning body and stretch into mouth；
Described saw blade stretches into mouth and is connected with described saw blade guide slit.
Preferably, described first positioning body is T-shaped；
Described second positioning body is L-shaped.
Preferably, described fixing pin runs through and is arranged on described first positioning body and described second positioning body.
Compared with prior art, this utility model has a following beneficial effect:
1, in this utility model, the first positioning body and described second positioning body are provided with multiple fixing pin, it is possible to will
This utility model is conveniently fixed；
2, in this utility model, the one end of the first positioning body and the one end of the second positioning body relatively form saw blade and lead
To seam, thus when carrying out osteotomy, it is possible to operating theater instruments is guided, it is to avoid the inclination of cutout；
3, this utility model simple in construction, rationally distributed, it is easy to promote.
Accompanying drawing explanation
By the detailed description non-limiting example made with reference to the following drawings of reading, of the present utility model other
Feature, purpose and advantage will become more apparent upon:
Fig. 1 is structural representation of the present utility model.
In figure:
1 is the first positioning body；
2 is the second positioning body；

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in detail.Following example will assist in the skill of this area
Art personnel are further appreciated by this utility model, but limit this utility model the most in any form.It should be pointed out that, to this
For the those of ordinary skill in field, without departing from the concept of the premise utility, it is also possible to make some deformation and
Improve.These broadly fall into protection domain of the present utility model.
In the present embodiment, the first metatarsal cervical region bone cutting positioner that this utility model provides, including the first positioning body and the
Two positioning bodies；
Wherein, described first positioning body removably connects with described second positioning body；The one end of described first positioning body with
The one end of described second positioning body forms saw blade guide slit relatively；
Described first positioning body and described second positioning body are provided with multiple fixing pin.
Described first positioning body is provided with dovetail groove；The other end of described second positioning body is provided with and described dovetail groove phase
The installed part joined；Described installed part is arranged in described dovetail groove, and can slide along the length direction of described dovetail groove.
The first metatarsal cervical region bone cutting positioner that this utility model provides, also includes milled screw；Wherein, described dovetail groove
Inside it is provided with the first screwed hole；The second screwed hole that the other end of described second positioning body is provided through；
Threaded described second screwed hole of described milled screw, the first screwed hole, thus formed described first positioning body with
Described second positioning body removably connects.
The V-shaped projection of one end of described first positioning body；The V-shaped groove of one end of described second positioning body；Described
