Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, complete explanation, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole realities
Apply example.Usually the component of the embodiments of the present invention described and illustrated in attached drawing can carry out cloth according to different configurations herein
It sets and designs.Therefore, requirement is not intended to limit to the detailed description of the embodiments of the present invention provided in attached drawing below
The scope of the utility model of protection, but it is merely representative of the selected embodiment of the utility model.Reality based on the utility model
Apply example, those skilled in the art's every other embodiment obtained without creative labor belongs to
The protection scope of the utility model.
Embodiment 1:
As shown in Fig. 1~2,
The electroresponse polymer shape memory acromioclavicular immobilizer that the utility model embodiment 1 provides, including rung by electricity
If answer bone plate 1 made of polymer shape memory material, the acromion hook 2 made of electroresponse polymer shape memory material and
