Abstract
A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a replacement procedure as compared to a more experienced surgeon who performs a greater number of procedures, to provide an improved likelihood of a favorable outcome approaching, if not exceeding, a likelihood of a favorable outcome as performed by a very experienced surgeon with the replacement procedure. Force sensing is included to aid in quantifying installation of an implant, particularly a cup into a pelvic bone.
Claims21
A tool for inserting a prosthesis into a portion of a bone, comprising:
- a force generator producing an insertion force, said insertion force configured to include a set of attributes, said set of attributes including a predetermination of a magnitude of said insertion force, a configurability for varying said magnitude of said insertion force, and a predetermined direction configured to communicate an application of said insertion force;
- a shaft, coupled to said force generator and configured to receive said insertion force, said shaft including a longitudinal axis extending from a proximal end to a distal end spaced apart from said proximal end with said longitudinal axis extending between said ends, the prosthesis coupled to said distal end, said insertion force configured to insert the prosthesis into the bone using said shaft with said predetermined direction aligned with said longitudinal axis;
- and
- a set of sensors coupled to said shaft;
- wherein said application of said insertion force is configured to produce a response of said shaft to said insertion force installing the prosthesis into the bone;
- and
- wherein said set of sensors are configured to provide a feedback of said response.
