The present teachings provide for a hand-held robotic system for use with a saw blade or other surgical tool. The hand-held robotic system also includes an instrument with a hand-held portion, a blade support coupled to the hand-held portion by a plurality of actuators, the actuators configured to move the blade support or tool support in a plurality of degrees of freedom relative to the hand-held portion. The system includes a localizer and a control system coupled to the localizer and the plurality of actuators. The control system is configured to control each of the plurality of actuators and/or the tool drive motor.

A surgical system includes a power module, a first handpiece, a first energy applicator, a second handpiece, and a second energy applicator. The power module includes a rechargeable cell, a motor, and a controller configured to connect the rechargeable cell to the motor. The first handpiece, being a first type having a first power requirement, and comprising a first shell defining a first void and a first opening for receiving the power module. The first energy applicator is configured to perform a first medical task. The second handpiece, being a second type and having a second power requirement, and comprising a second shell defining a second void and a second opening for receiving the power. The second energy applicator is configured to perform a second medical task. The controller is configured to control the power module based on the type of handpiece identified.

A sensor system includes a first member that extends along a rotational axis and has a surface disposed circumferentially about the rotational axis. A conductive element is disposed on the surface of the first member and disposed about the rotational axis. A second member extends along the rotational axis. A rotational position between the first member and the second member is adjustable. A target is mounted to and rotatable with the second member and is movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is spaced further from the conductive element in the second position compared to the first position. The conductive element detects a change in movement of the target from the first position to the second position for any rotational position between the first member and the second member.

A drill for driving a drill bit into a solid object such as bone. The drill includes a rotor with a bore that transmits rotational movement to the drill bit. The drill bit extends through the rotor bore. A probe extends forward from the drill to measure bore depth. The probe is moveably mounted to the drill so as to extend into the rotor bore. As the drill and drill bit advance forward the probe remains static. As a result of the advancement of the drill the rotor extends over the proximal end of the probe.

Disclosed is an assembly for holding a tool. The assembly may selectively reduce and/or eliminate vibrations received and felt by a user. Reducing vibrations may reduce or eliminate chatter at a working end of a tool.

An end effector is disclosed for use with a surgical robotic manipulator and a cutting accessory. The end effector comprises a nose tube for receiving the cutting accessory and an actuator for driving the cutting accessory. The end effector may also comprise a mounting fixture for coupling the end effector to the surgical robotic manipulator and a handle for gripping by the user. The handle may be coupled to the nose tube and configured to rotate about the axis of the nose tube. The end effector may also comprise a lever coupled to the handle and moveable between depressed and released positions. The end effector may further comprise an activator coupled to the lever and configured to interact with a sensor for sensing the position of the lever.

A re-usable medical procedure power tool includes enclosed housing including a tool attachment portion, a handle portion connected to a tool attachment portion and a power portion. A removable, single use, contamination-blocking cover substantially covering the housing, the handle portion the power portion. The cover also includes an opening adjacent an exposed first end of the tool attachment portion, whereby a tool accessory is selectively attached to and removed from the first end of the tool attachment portion during a medical procedure.

A surgical guidance device is cannulated for passage of a guidewire or pin and includes a hand grip and differential control assembly for driving the guidewire or pin and differentially driving a screw, such as but not limited to a pedicle screw, into bone. The differential control assembly resides in a housing, and includes a differential control assembly for gripping and locking or releasing the guidewire or pin and effecting directional movement (relative to the user holding the surgical guidance device) either distally into the bone or proximally away from bone to thereby drive or retract the guidewire. The differential control assembly also allows distal or proximal drive of a screw, such that one or both the guidewire and screw can be passed proximally or distally alone or together.

A handheld surgical system includes an instrument, a depth measurement attachment, and a controller. The instrument includes a housing and a motor that is positioned within the housing. The depth measurement attachment is removably coupled to the instrument. The depth measurement attachment includes a first sensor that is configured to provide a vibration signal associated with a vibration of the motor during a drilling process, a second sensor that is configured to provide a displacement signal associated with a displacement of a drill bit during the drilling process, and a controller. The controller is configured to receive the vibration signal and the displacement signal. The controller is also configured to determine a characteristic of the motor based on the vibration signal using an algorithm and determine a breakthrough event based on the motor characteristic and the displacement signal.

A surgical device is disclosed for attachment to a body of a surgical tool usable to manipulate a desired tissue in a surgical site within a patient, the surgical device may include a housing with at least one each of a projecting device, an imaging device and/or an illuminating device. The housing may be removably attachable to the body in an operatively-aligned orientation relative to the body. The projecting device(s) may emit an optical targeting marker from the exit port in a targeting direction onto the surgical site. The illuminating device(s) may illuminate the surgical site. The one imaging device(s) may obtaining an image of the surgical site.
