Systems and devices may include a motor operatively coupled to a driveshaft configured to be driven in a first direction in a first mode for impaction and a second direction in a second mode for retraction. Systems and devices may include an anvil configured to be operatively coupled to an implement. Systems and devices may include an impaction cam operatively coupled to the driveshaft, wherein: the impaction cam, when in an impaction position, is configured to strike the anvil when driven by the driveshaft in the first direction to drive the anvil in an impaction direction. Systems and devices may include a retractor configured to be driven by the retraction cam in the second direction, wherein the retractor is configured to strike the anvil to drive the anvil in a retraction direction.

Surgical systems and methods for positioning a workpiece involve a first tool assembly including one of a coupler or a receiver, and a second tool assembly with an interface adapted to attach to the workpiece and including the other one of the coupler or the receiver. A tool guide is configured to mount to a surgical robot. The tool guide defines an aperture through which the first tool assembly is configured to extend. The tool guide is configured to support the first tool assembly and enable the first tool assembly to pivot relative to the tool guide to facilitate engagement between the coupler and receiver to align the first and second tool assemblies.

A motor-driven orthopedic impacting tool is provided for orthopedic impacting in the hips, knees, shoulders and the like. The tool is capable of holding a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the broach, implant, or other surgical implement from the opening. A stored-energy drive mechanism stores potential energy and then releases it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter in accordance with a patient profile.

An orthopaedic surgical instrument may include an elongated body with a broach end and an impactor end. The body may be straight or curved. A latch lever may be pivotally coupled to the elongated body. The latch lever may be moveable between an open position and a latched position in which the latch lever is retained within the body. A surgical broach may be rigidly attached to the broach end of the elongated body. An automated surgical impactor may be attached to the impactor end.

The dual-purpose orthopedic instrument includes an elongated body, an impactor block formed from a first end of the elongated body selectively couplable with a modular impactor head and a strike block formed from a second end of the elongated body including a strike surface for selectively receiving a strike force thereof. An externally accessible channel formed within the elongated body has a size and shape for pass-through reception and select retention of an extractor rod therein. As such, the elongated body is usable as a modular impactor when the impactor block is selectively coupled with the impactor head and as a weight of a slap hammer when selectively coupled with the extractor rod in slidable relation relative thereto.

Disclosed herein are linear electric surgical hammer impact tools and methods of use thereof. The linear electric surgical hammer impact tools can include a shuttle located inside a cavity of a housing. A wall of the shuttle defines a plurality of grooves extend from a first end of the shuttle to a second end of the shuttle. A piston can be located at least partially within the shuttle and arranged along the longitudinal axis of the housing. The piston includes protrusions and each of the protrusions can be arranged to travel within a respective one of the grooves of the shuttle. Motion of the piston in a first direction causes the piston to contact the first end of the shuttle and motion of the piston in a second direction causes the piston to contact the second end of the shuttle.
