Abstract
An osteosynthetic force transmitting and positioning apparatus has two force transmitting members one of which is slidably telescoped into the other and each of which or at least one of which is connected or is connectable to one or more connecting components for bone screws, bone pins and/or other types of fasteners which secure the connectors to discrete bones, to fragments of bones or to osteosynthetic plates. The connections between the force transmitting members and the connecting components are such that the orientation of the fasteners can be altered in the direction of any one of three axes which are disposed at right angles to each other. Such connections can include fulcra, hinges, pivots, pin-and-hole couplings or others.
Claims22
An osteosynthetic fixation and force transmitting apparatus, comprising first and second force transmitting members having a common axis;
- means for moving said members relative to each other in a predetermined direction along said common axis;
- means for at least indirectly connecting said members to at least one bone, comprising a first connecting component mounted on one of said members for pivotal movement between a plurality of different positions;
- a fulcrum pivotally connecting said first connecting component to said one member, said fulcrum defining a predetermined axis which is substantially normal to said common axis;
- means for releasably locking said first connecting component in a selected position relative to said one member, said connecting means further comprising a second connecting component mounted on the other of said members for angular movement about a second axis which is normal to said direction and to said predetermined axis;
- and means for releasably locking said second connecting component in a selected angular position relative to said other member.
An osteosynthetic fixation and force transmitting apparatus, comprising first and second force transmitting members having a common axis;
- means for moving said members relative to each other along said common axis;
- means for at least indirectly connecting said members to at least one bone, comprising a connecting component mounted on one of said members for pivotal movement between a plurality of different positions, said component comprising a bracket having a first leg and a second leg extending at right angles to said first leg and mounted on said one member;
- a first fulcrum pivotally connecting said first leg to said one member and defining a predetermined axis which is substantially normal to said common axis;
- a second fulcrum connecting said second leg to said one member for angular movement about an axis which is parallel to said direction;
- and means for releasably locking said connecting component in a selected position relative to said one member.
An osteosynthetic fixation and force transmitting apparatus, comprising first and second force transmitting members having a common axis;
- means for moving said members relative to each other along said common axis;
- means for at least indirectly connecting said members to at least one bone, comprising a connecting component mounted on one of said members for pivotal movement between a plurality of different positions;
- a fulcrum pivotally connecting said connecting component to said one member, said fulcrum defining a predetermined axis which is substantially normal to said common axis;
- means for releasably locking said connecting component in a selected position relative to said one member;
- and means for changing the angular position of said component, said means for changing the angular position being connected to each of said members.
