Kinematic couplings for affixing an end effector to a robotic arm covered in a surgical drape are provided. A kinematic coupling can include one or more attachment mechanisms for affixing the kinematic coupling to the robotic arm with or without piercing the surgical drape positioned thereover. The kinematic coupling can be configured to interchangeably engage with a number of different end effectors, including surgical instruments, cutting guides or jigs, tool holders, and so on.

Kinematic coupling

A rotary tool includes a tool body and a powered rotary cutting tooltip that is oriented and positioned relative to the tool body by a plurality of processor-controlled actuators that provide degrees of freedom. The processor uses a surgical tracking system to identify the pose of the tool body and the tooltip relative to a patient's anatomy and controls the actuators to maintain the tooltip within a predetermined cutting plan to compensate for deviation of a surgeon's hand or a robotic arm controlling the tool body during a cutting operation.

Computer controlled surgical rotary tool

Devices, systems, and methods for measuring a force applied to a joint during a surgical procedure are disclosed. The device includes an insertion tool, a handle, and one or more force indicators. The insertion tool includes an insertion end and a base end. The one or more force indicators may be attached to the insertion tool and the handle. The insertion end of the device may be inserted into a joint during a surgical procedure and used to apply a force to the joint and/or measure the force using the one or more force indicators when the force is applied.

Force-indicating retractor device and methods of use

Methods and systems of placing a medical fastener at a predetermined depth in a bone are described. A surgical tool can include an attachment assembly configured to interchangeably engage a medical fastener and a cutting element or bone removal tool and a drive assembly coupled to the attachment assembly. The attachment assembly can be configured to automatically release the medical fastener in response to the drive assembly reaching its end or distal-most position to place the medical fastener at a predetermined depth within the bone.

Methods and systems for robotic-assisted insertion of medical fasteners

A system () and method () for identifying cutting tools for use during a surgical procedure are described. For example, the system includes a cutting tool assembly () including a shaft () having a cutting element () and at least one identifying feature () that uniquely corresponds to the cutting element. The system further includes a drive assembly () including a reference pin (), a motor () mechanically connected to the drive assembly, a control unit () configured to activate the motor to move the cutting tool assembly such that the reference pin engages with the at least one identifying feature, a sensor system () configured to determine positioning information related to the reference pin when the reference pin engages the at least one identifying feature, and a computing unit () configured to receive the positioning information from the sensor system and identify the cutting element based upon the position information.

Feature-based surgical tool identification

Methods of measuring a force using a tracking system are disclosed. A first vector is determined between a first tracking array and a second tracking array on a tool. The tool has a flexible portion that has a known modulus of elasticity and moment of inertia. A force is applied to the tool, and a second vector is determined between the first tracking array and the second tracking array. An amount of deflection is determined for the tool, and the magnitude and direction of the applied force are determined based on at least the amount of deflection, the modulus of elasticity and the moment of inertia. Information pertaining to the magnitude and direction of the applied force is provided to a user.
