Abstract: Tools, assemblies, surgical systems enable impacting a prosthesis into a surgical site. The tool has an impactor head with a surface to receive an impact force that is manually imparted by a user. A tool shaft has a distal portion and a proximal portion fixed to the impactor head. The tool shaft can be supported by a robotically manipulated tool guide for alignment of the tool shaft relative to the surgical site. A compliance mechanism of the tool has a proximal body coupled to the distal portion of the tool shaft and a distal body supported by the proximal body. The distal body is adapted to releasably attach directly to the prosthesis. The distal body is moveable relative to the proximal body for providing compliant motion of the distal body and prosthesis relative to the tool shaft in response to the impact force that is manually imparted by the user.

Abstract: A tool for positioning a workpiece with a surgical robot. The tool comprises a mount adapted to attach to the surgical robot. A first assembly is provided and extends along an axis. A pivot bearing is coupled to the mount and supports the first assembly for rotation and translation about the axis and for at least partial articulation relative to the mount. A second assembly is provided and comprises an interface adapted to attach to the workpiece. One of the first assembly and the second assembly comprises a coupler and the other of the first assembly and the second assembly comprises a receiver shaped to engage the coupler to align the second assembly and the first assembly along the axis.
