Abstract
Abstract An osteosynthetic holding system is provided which comprises bone anchoring elements, each of which has a clamping element as well as two receptacles arranged thereon for receiving holding bars. The receptacles have blocking elements arranged thereon which define accesses to the receptacles. Two holding bars are provided which are insertable into the receptacles of each bone anchoring element. The clamping element can be tightened to clamp the two holding bars against the receptacles, thereby fixing the position of each bone anchoring element with respect to the other. The blocking elements, together with the clamping element in a tightened state, constrict the accesses to said receptacles in a direction transverse to a longitudinal direction of the holding bars such that the holding bars no longer fit through the accesses. The blocking elements of the two receptacles are dimensioned such that upon releasing the clamping element, the accesses to the two receptacles are enlarged to enable each of the holding bars to fit through its respective receptacle in turn as the clamping element is released.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
An osteosynthetic holding system comprising: a plurality of bone anchoring elements, each having two receptacles arranged thereon; said receptacles each having a respective blocking element arranged thereon defining an access to the receptacle; respective holding bars, each of which is insertable into respective receptacles of at least two bone anchoring elements; a clamping element, said clamping element clamping the holding bars against said receptacles in a tightened state thereof, and together with said blocking element in the tightened state constricting the accesses to said receptacles in a direction transverse to a longitudinal direction of said holding bars such that said holding bars no longer fit through said accesses; wherein the blocking elements of the two receptacles are of such different dimensions that upon releasing said clamping element, the accesses to the two receptacles are so enlarged one after the other that each of said holding bars fits through its respective receptacle in turn as the clamping element is released.
Claim 2
Dependent Claim
159 words
An osteosynthetic holding system comprising: a plurality of bone anchoring elements, each having two receptacles arranged thereon; said receptacles each having a respective blocking element arranged thereon defining an access to the receptacle; respective holding bars, each of which is insertable into respective receptacles of at least two bone anchoring elements; a clamping element, said clamping element clamping the holding bars against said receptacles in a tightened state thereof, and together with said blocking element in the tightened state constricting the accesses to said receptacles in a direction transverse to a longitudinal direction of said holding bars such that said holding bars no longer fit through said accesses; wherein the blocking elements of the two receptacles are of such different dimensions that upon releasing said clamping element, the accesses to the two receptacles are so enlarged one after the other that each of said holding bars fits through its respective receptacle in turn as the clamping element is released.

A holding system in accordance with claim 2 , wherein said receptacles are of groove-shaped construction, and edge regions of the groove-shaped receptacles form said blocking elements.
Claim 5
Dependent Claim
27 words
A holding system in accordance with claim 3 , wherein free edges of said two groove-shaped receptacles arranged on each bone anchoring element are of different height.
Claim 6
Dependent Claim
27 words
A holding system in accordance with claim 1 , wherein said receptacles are of groove-shaped construction, and edge regions of the groove-shaped receptacles form said blocking elements.
Claim 7
Dependent Claim
27 words
A holding system in accordance with claim 5 , wherein free edges of the two groove-shaped receptacles arranged on each bone anchoring element are of different height.
Claim 8
Dependent Claim
134 words
A bone anchoring element comprising: two receptacles adapted to receive holding bars; blocking elements arranged on each receptacle defining an access to the receptacle; a clamping element, said clamping element adapted for clamping the holding bars against said receptacles in a tightened state thereof, and together with said blocking element in the tightened state constricting the accesses to said receptacles in a direction transverse to a longitudinal direction of said holding bars such that said holding bars no longer fit through said accesses; wherein the blocking elements of the two receptacles are of such different dimensions that upon releasing said clamping element, the accesses to the two receptacles are so enlarged one after the other that each of said holding bars fits through its respective receptacle in turn as the clamping element is released.
Claim 9
Dependent Claim
134 words
A bone anchoring element comprising: two receptacles adapted to receive holding bars; blocking elements arranged on each receptacle defining an access to the receptacle; a clamping element, said clamping element adapted for clamping the holding bars against said receptacles in a tightened state thereof, and together with said blocking element in the tightened state constricting the accesses to said receptacles in a direction transverse to a longitudinal direction of said holding bars such that said holding bars no longer fit through said accesses; wherein the blocking elements of the two receptacles are of such different dimensions that upon releasing said clamping element, the accesses to the two receptacles are so enlarged one after the other that each of said holding bars fits through its respective receptacle in turn as the clamping element is released.
