Abstract
Abstract An elastic clip for osteosynthesis for connecting at least two bone parts together, comprising a body having at least two spaced legs, each leg having a lower end which can be inserted into a bone part and each having an upper end, the upper ends of said at least two legs being attached to corresponding ends of an elastic bridge which is deformable by pressure and which preferably comprises at least two elongated sections which extend alongside each other. Preferably, the clip has four legs attached in pairs to each of the ends of the bridge, the legs of each pair being attached together. The two elongated sections have at least a portion where they are not connected together, so that the two bridge sections can be forced apart to hold the bone parts in place. Alternatively, the two bridge sections are spaced apart and brought together to hold two bone parts together with a prescribed spacing.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
247 words
A clip for osteosynthesis for connecting at least two bone parts together, the clip comprising two staple-shaped members, the two members being disposed alongside each other and each having two leg portions and a bridge portion between the leg portions, adjacent leg portions of each member being attached in a connecting line along a substantial portion of the length of the adjacent leg portions, the joined leg portions each comprising a combined leg and each adjacent leg portion having a lower end which can be inserted into a bone part and each having an upper end, the upper ends of said adjacent leg portions being attached to corresponding ends of respective ones of said bridge portions, the bridge portions being elastic and being deformable by pressure and each comprising an elongated section extending alongside each other, said elastic bridge elongated sections being unconnected along their length and having a bowed shape such that they are separated from each other by a space and being adapted to receive an expansive force between the elongated sections tending to expand the space in order to draw the legs toward each other and being adapted to receive a compressive force tending to decrease the space in order to move the legs apart, said combined legs moving toward each other when said elastic bridge elongated sections receive said expansive force such that the lower ends of the opposed combined legs move closer together than the upper ends of the opposed combined legs.
Claim 2
Dependent Claim
247 words
A clip for osteosynthesis for connecting at least two bone parts together, the clip comprising two staple-shaped members, the two members being disposed alongside each other and each having two leg portions and a bridge portion between the leg portions, adjacent leg portions of each member being attached in a connecting line along a substantial portion of the length of the adjacent leg portions, the joined leg portions each comprising a combined leg and each adjacent leg portion having a lower end which can be inserted into a bone part and each having an upper end, the upper ends of said adjacent leg portions being attached to corresponding ends of respective ones of said bridge portions, the bridge portions being elastic and being deformable by pressure and each comprising an elongated section extending alongside each other, said elastic bridge elongated sections being unconnected along their length and having a bowed shape such that they are separated from each other by a space and being adapted to receive an expansive force between the elongated sections tending to expand the space in order to draw the legs toward each other and being adapted to receive a compressive force tending to decrease the space in order to move the legs apart, said combined legs moving toward each other when said elastic bridge elongated sections receive said expansive force such that the lower ends of the opposed combined legs move closer together than the upper ends of the opposed combined legs.
Claim 3
Dependent Claim
14 words
A clip according to claim 1, wherein the adjacent leg portions are welded together.
Claim 4
Dependent Claim
17 words
A clip according to claim 1, wherein the elongated sections are welded together, at least in part.
Claim 5
Dependent Claim
16 words
A clip according to claim 1, wherein said clip comprises a material comprising biocompatible stainless steel.
Claim 6
Dependent Claim
16 words
A clip according to claim 1, wherein said elongated bridge sections have at least one step.
Claim 7
Dependent Claim
266 words
A clip for osteosynthesis for connecting at least two bone parts together, the clip comprising two staple-shaped members, the two members being disposed alongside each other and each having two leg portions and a bridge portion between the leg portions, corresponding leg portions of each member being attached in a connecting line along a substantial portion of the length of the leg portions, the joined leg portions each comprising a combined leg and each adjacent leg portion having a lower end which can be inserted into a bone part and each having an upper end, the upper ends of said leg portions being attached to corresponding ends of said bridge portions, each bridge portion being bowed away from the other bridge portion to form a space therebetween and being unconnected to each other along their length, each bridge portion having a longitudinal extent and being deformable by pressure and each comprising an elongated section which is deformable in a direction transverse to the longitudinal extent of said bridge sections to move said bone parts closer together or away from each other by a prescribed distance, said elongated bridge sections having said bowed shape with the bow being in a direction transverse to the longitudinal extent of the bridge section so that if the bow is increased, the legs are drawn together, and if the bow is reduced, the legs are moved apart, said combined legs moving toward each other when said bow is increased such that the lower ends of the opposed combined legs move closer together than the upper ends of the opposed combined legs.
Claim 8
Dependent Claim
266 words
A clip for osteosynthesis for connecting at least two bone parts together, the clip comprising two staple-shaped members, the two members being disposed alongside each other and each having two leg portions and a bridge portion between the leg portions, corresponding leg portions of each member being attached in a connecting line along a substantial portion of the length of the leg portions, the joined leg portions each comprising a combined leg and each adjacent leg portion having a lower end which can be inserted into a bone part and each having an upper end, the upper ends of said leg portions being attached to corresponding ends of said bridge portions, each bridge portion being bowed away from the other bridge portion to form a space therebetween and being unconnected to each other along their length, each bridge portion having a longitudinal extent and being deformable by pressure and each comprising an elongated section which is deformable in a direction transverse to the longitudinal extent of said bridge sections to move said bone parts closer together or away from each other by a prescribed distance, said elongated bridge sections having said bowed shape with the bow being in a direction transverse to the longitudinal extent of the bridge section so that if the bow is increased, the legs are drawn together, and if the bow is reduced, the legs are moved apart, said combined legs moving toward each other when said bow is increased such that the lower ends of the opposed combined legs move closer together than the upper ends of the opposed combined legs.
