Front end be arranged jaw, the direction of jaw outwardly, the hinged linear gear rack of tail inner side of the expansion arm two, the tail of linear gear rack
Portion is connect with resilient strips one, and resilient strips one and linear gear rack are L-shaped, and the junction of resilient strips one and linear gear rack is hinged on expansion
Stretch one's arms two tail inner side, one side external surface of linear gear rack be arranged row's slip teeth, the tail portion of the expansion arm one, which is bent outwardly, prolongs
It stretches, multiple tracks sliding slot is arranged in the trailing exterior surface of expansion arm one, and sliding slot is used cooperatively with slip teeth, the feelings that sliding slot is squeezed in no external force
It can be stuck in slip teeth under condition.
Preferably, the tail portion of the expansion arm one to pin shaft distance be greater than pin shaft to jaw distance, expansion arm one
Tail portion curves inwardly to the part between pin shaft.
Preferably, the tail portion of the expansion arm two to pin shaft distance be greater than pin shaft to jaw distance, expansion arm two
Tail portion curves inwardly to the part between pin shaft.
Preferably, further include resilient strips two, the resilient strips two are fixed in the inner webs of expansion arm one, resilient strips two with
Resilient strips one are corresponding to be staggered, and when being compressed by external force, the front of resilient strips two is against on the inner sidewall of expansion arm two, returns
The front end of spring one is against on the inner sidewall of expansion arm one.
Using technical solution of the present invention, can obtain it is below the utility model has the advantages that
Extension fixture for bone surgery of the invention is when carrying out bone-operating for expanding that when especially spinal operation
This adjacent bone, this extension fixture are not easy to unclamp after being softened with one-handed performance, this extension fixture, this extension fixture knot
Structure is simple and easily operated.
Detailed description of the invention
Brief description is made to content expressed by each attached drawing of this specification and the label in figure below:
Fig. 1 is this extension fixture closed state structural schematic diagram；
Fig. 2 is this extension fixture expansion state structural schematic diagram；
Label in above-mentioned figure is equal are as follows: 1, expansion arm one；2, expansion arm two；3, linear gear rack；4, slip teeth；5, sliding slot；6, it springs back
Item one；7, resilient strips two；8, pin shaft；9, jaw.
Specific embodiment
Below against attached drawing, by the description of the embodiment, to for example related each structure of a specific embodiment of the invention
The works such as the shape of part, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle are further
Detailed description.
As shown in Figure 1, 2, this includes expansion arm 1, expansion arm 22 and linear gear rack for the extension fixture of bone surgery
3, expansion arm 1 and expansion arm 22 are hinged by pin shaft 8, and expansion arm 1, expansion arm 22 are hinged on by pin shaft 8
Together similar to the shape of scissors, the front end setting jaw 9 of expansion arm 1 and expansion arm 22, the direction of jaw 9 outwardly, is expanded
The hinged linear gear rack 3 of the tail inner side of arm 22, the tail portion of linear gear rack 3 are connect with resilient strips 1, resilient strips 1 and linear teeth
Item 3 is L-shaped, and the junction of resilient strips 1 and linear gear rack 3 is hinged on the tail inner side of expansion arm 22, linear gear rack 3 one
Row's slip teeth 4 is arranged in side external surface, and the tail portion of expansion arm 1 is bent outwardly extension, and the trailing exterior surface setting of expansion arm 1 is more
Road sliding slot 5, sliding slot 5 are used cooperatively with slip teeth 4, and sliding slot 5 can be stuck in slip teeth 4 in the case where no external force squeezes.
As shown in Figure 1, the distance of the tail portion of expansion arm 1 to pin shaft 8 is greater than the distance that pin shaft 8 arrives jaw 9, expansion arm one
1 tail portion curves inwardly to the part between pin shaft 8.The distance of the tail portion of expansion arm 22 to pin shaft 8 is greater than pin shaft 8 and arrives jaw 9
Distance, the tail portion of expansion arm 22 curves inwardly to the part between pin shaft 8.
As shown in Figure 1, 2, resilient strips 27 are additionally provided with, resilient strips 27 are fixed in the inner webs of expansion arm 1, resilient strips
27 it is corresponding with resilient strips 1 be staggered, when being compressed by external force, the front of resilient strips 27 is against the inside of expansion arm 22
