Abstract
Abstract In an orthopedic surgical holding device for a correcting rod, having a bone plate which can be fastened on the bone, a receiver device for the correcting rod and a fixing device maintaining the correcting rod in the receiver device. An optimal transfer of the occurring forces and moments is achieved in that the bone plate can be fixed independently of the receiver device (10) and has a bearing for the receiver device, and in that the receiver device can be pushed into the bearing from the proximal side and in the course of this extends through the bone plate and extends beyond it on the distal side for receiving the correcting rod.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
161 words
An orthopedic surgical holding device for a correcting rod, comprising: a bone plate for fastening onto a bone, said bone plate defining a proximal side, a distal side and a center line; a receiver device mounted to said bone plate for receiving the correcting rod, said receiver device having a collar and a outer surface on its end; and a fixing device mounted to said receiver device for maintaining the correcting rod in said receiver device, wherein said bone plate includes a bearing which engages said receiver device such that said receiver device extends through said bearing from said proximal side beyond said distal side of said bone plate where it receives the correcting rod, such that said outer surface assumes a position that is one of a recessed position relative to said proximal side and a flush position relative to said proximal side, and such that said bone plate can be fixed to the bone independently of said receiver device.
Claim 2
Dependent Claim
161 words
An orthopedic surgical holding device for a correcting rod, comprising: a bone plate for fastening onto a bone, said bone plate defining a proximal side, a distal side and a center line; a receiver device mounted to said bone plate for receiving the correcting rod, said receiver device having a collar and a outer surface on its end; and a fixing device mounted to said receiver device for maintaining the correcting rod in said receiver device, wherein said bone plate includes a bearing which engages said receiver device such that said receiver device extends through said bearing from said proximal side beyond said distal side of said bone plate where it receives the correcting rod, such that said outer surface assumes a position that is one of a recessed position relative to said proximal side and a flush position relative to said proximal side, and such that said bone plate can be fixed to the bone independently of said receiver device.
