Abstract
Abstract A device for osteosynthesis is of the kind prepared of material which exhibits form-memory effect, is made of wire and contains a working part and locking components. According to the invention the locking components are made as plunge legs; the working part consists of alternating arched components, with arch length exceeding 180°; and the adjacent components are placed to different sides of the line connecting their bending points to the plunge legs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
The device for osteosynthesis is of the kind prepared of material which exhibits form-memory effect, is made of wire and contains a working part and locking components, and is characterized by the fact that, the locking components are made as plunge legs; the working part consists of alternating arched components, with arch length exceeding 180°; and the adjacent components are placed to different sides of the line connecting their bending points to the plunge legs.
Claim 2
Dependent Claim
34 words
The device according to claim 1 is characterised by the locking components made as the plunge legs one of which is supplied with an arched element made into the shape of adjoining bone surface.
Claim 3
Dependent Claim
32 words
The device according to claim 2 is characterised by the fact that the length of the leg supplied with the arched element is 1,5-2,0 times greater than that of the other leg.
Claim 4
Dependent Claim
27 words
The device according to claim 1 is characterised by the fact that the working part's length is 1,5-2,0 times shorter than the distance between the plunge legs.
Claim 5
Dependent Claim
47 words
The device according to claim 1 is characterised by the fact that the working part is formed by the arched components with the arch length exceeding 180° and the adjacent components located at different sides of the line which connects their bending points with the plunge legs.
Claim 6
Dependent Claim
34 words
The device according to claim 1 is characterised by the fact that the locking components are bent in either one, parallel or perpendicular planes with at least one of them being a closed loop.
Claim 7
Dependent Claim
