Abstract
A surgical clamping device is provided for receiving distal ends of handles having bone attachment members disposed thereon in a recess disposed in the surgical clamping device. When an adjustment mechanism is in a first state, the distal ends of the handles are able to pivot and, optionally, to move axially within the recess of the surgical clamping device. When the adjustment mechanism is placed into a second state by adjusting the adjusting mechanism, the surgical clamping device applies a clamping force to the distal ends of the handles such that they are fixed within the recess of the surgical clamping device.
Claims19
A surgical assembly comprising at least one surgical clamping device and a plurality of handles, the at least one clamping device comprising:
- two opposing clamping members;
- at least one recess disposed in the surgical clamping device and adapted to receive distal ends of the plurality of handles having bone attachment members disposed thereon, wherein the recess is defined between the two clamping member, and wherein the recess comprises one or more grooves disposed on one of the clamping members or on opposing faces of the clamping members;
- an adjusting mechanism adapted to adjust the recess between a first state in which at least one of the distal ends of the plurality of handles is pivotable within the recess, wherein the distal ends of the plurality of handles are supported by the one or more grooves of the clamping members in the first state such that the distal ends cannot be removed from the recess without widening a distance between the clamping members, and a second state in which the distal ends of the handles are axially and pivotably fixed within the recess;
- and
- wherein the distal end of each handle comprises a ball joint member adapted to pivot and to axially move within the recess in the first state, and adapted to be fixed within the recess in the second state.
A surgical assembly comprising:
- a clamping device comprising first and second juxtaposed clamping plates having facing surfaces, each facing surface having a curved groove extending along a first axis of the first clamping plate and along a second axis of the second clamping plate, a first and second alignment element engaging each clamping plate for maintaining the first axis along the first clamping plate parallel to the second axis along the second clamping plate, the first clamping plate having a threaded bore therein and the second clamping plate having a tapered bore therein, the threaded bore and tapered bore both extending along a third axis transverse to the first and second axis;
- a pair of handle members each having a ball-shaped head mounted within the curved groove of the first and second clamping plates;
- and
- an adjusting mechanism having a shaft received within the threaded and tapered bores of the first and second clamping plates, the adjusting mechanism shaft including a threaded end operatively engaging the threaded bore of the first clamping plate and an elastic member mounted on the shaft engaging the second clamping plate the adjustment mechanism capable of moving the first and second clamping plates towards one another.
