| Abstract |
Surgical system for positioning prosthetic component and/or for constraining movement of surgical tools
A surgical system for positioning a prosthetic
component on an anatomy of a patient includes a
surgical tool configured to engage the prosthetic component,
a force system configured to provide at least some
force to the surgical tool, and a controller programmed to
compare a target pose of the prosthetic component and an
actual pose of the prosthetic component engaged by the
surgical tool and generate control signals that cause the
force system to allow movement of the surgical tool within
a range of movement and provide haptic feedback to
constrain a user's ability to manually move the surgical
tool beyond the range of movement. The haptic feedback
resists movement of the surgical tool by the user that
would cause substantial deviation between at least one aspect
of the actual pose of the prosthetic component and a
corresponding aspect of the target pose of the prosthetic
component. The controller is programmed to generate
control signals that cause the force system to maintain the
haptic feedback as the user implants the prosthetic component
on the anatomy. |
