A surgical system includes a surgical robot with an end effector that supports a drive assembly, a manual interface, and a trigger assembly. A cutting tool is attached to the drive assembly and rotatable about a cutting axis. A method includes positioning, with the surgical robot, the cutting tool relative to a surgical site to align the cutting axis with a predetermined trajectory. A user engages the trigger assembly for rotating the cutting tool about the cutting axis with the drive assembly and advancing the cutting tool along the predetermined trajectory at the surgical site to a first depth. A user applies force to the manual interface for rotating the cutting tool about the cutting axis and advancing the cutting tool along the predetermined trajectory to a second depth greater than the first depth.

A device for ligament balancing includes a mount at a first end of the device and a head portion at a second end of the device, the head portion having a substantially planar surface, a first paddle, and a second paddle, wherein the first and second paddle are rotatable about a first longitudinal axis and a second longitudinal axis, respectively, relative to the substantially planar surface. The device further includes a stem extending from the head portion and a shaft extending between the stem and the mount. The mount includes a coupling portion configured to couple the device to a robotic device such that movement of the device is controlled by the robotic device.

System and method for ligament balancing using robotically held device

Disclosed herein are gear shifters to reverse an output shaft rotation and a method for using the same. A gear shifter in accordance with the present invention may include a housing, an input shaft, an output shaft and an idler shaft. The input shaft may have input gears, the output shaft may have output gears and the idler shaft may have idler gears. The output shaft may be slidably coupled with the input shaft and the idler shaft to rotate in a first direction in a first position and in a second opposite direction in a second position. A method of reversing an output shaft direction using a gear shifter may include the steps of pushing the gear shifter in a first direction to rotate the output shaft in a first direction and pushing the gear shifter in a second direction to rotate the output shaft in a second direction.

End effectors for driving tools at surgical sites along trajectories maintained by surgical robots. A tool has interface and working ends. An end effector has a mount to attach to the surgical robot, and an actuator configured to generate torque. A drive assembly with a geartrain translates rotation from the actuator into rotation of a drive conduit supported about an axis. A rotational lock operatively attached to the drive conduit releasably secures the tool for concurrent rotation about the axis, and an axial lock releasably secures the tool for concurrent translation with the drive conduit along the trajectory maintained by the surgical robot. The axial lock is operable between a release configuration where relative movement between the drive assembly and the tool is permitted along the axis, and a lock configuration where relative movement between the drive assembly and the tool is restricted along the axis.
