Abstract
A modular torque-applying surgical tool includes a driver member having a proximal handle and a distal end, and a torque-applying insert removably and replaceably attachable to the distal end of the driver member. The torque-applying insert is designed to be deformable when a predetermined level of torque is achieved, or when the insert is subjected to a torque in excess of a predetermined magnitude such that the insert is effective to apply to a driven member a predetermined minimum torque.
Claims20
A modular torque-applying surgical tool, comprising:
- a driver member having a proximal handle and a distal end;
- and
- a separate torque-applying insert removably and replaceably matable to the distal end of the driver member in an interference fit, and the insert being deformable when subjected to a torque at or above a predetermined magnitude such that a distal end of the insert is adapted to directly contact and is effective to apply to a driven member a predetermined minimum torque.
A modular torque-applying surgical tool system, comprising:
- a driver member having a proximal handle and a distal end, the distal end including an insert receiving socket;
- and
- a plurality of separate torque-applying inserts, each of the inserts being removably and replaceably matable within the insert receiving socket of the driver member in an interference fit, and each insert being deformable when subjected to a torque level at or above a different, predetermined magnitude such that a distal end of each insert is adapted to directly contact and is effective to apply to a driven member a predetermined minimum torque.
