Abstract: Surgical systems and methods involving a reamer tool and a surgical robotic arm. The reamer tool has a shaft, a tool engagement surface coupled to the shaft, and a reamer head attached to the shaft. The surgical robotic arm supports a guide that can receive the reamer tool. The guide has a pair of arms, each arm extending to an arm end and the arm ends being spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms. The guide enables a portion of the shaft to move through the opening between the arm ends such that the shaft portion can enter and exit the channel. The arms define a guide engagement surface that is arc-shaped and that enables contact with the tool engagement surface to facilitate alignment of the reamer tool and the guide.

Abstract: Surgical systems and methods involve a robotic arm with a first mounting portion that releasably receives a sterile barrier assembly and a second mounting portion associated with a surgical component. An illumination device is coupled to the robotic arm. Controller(s) detect, using one or more sensors, a condition associated with installation of one or more of the sterile barrier assembly and the second mounting portion to the first mounting portion. The controller(s) control the illumination device to indicate the condition to a user.

Abstract: An assembly for a surgical arm includes a tool to position a prosthesis and an end effector. The tool has a tool shaft extending along a tool axis and a tool engagement surface. The end effector has a mount attachable to the surgical arm, a body portion extending from the mount, a distal end, and a guide portion is at the distal end of the body portion to receive the tool. The guide portion has a pair of arms, each arm extending to an arm end and the arm ends are spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms and extends along a guide axis. The arms define an arc-shaped guide engagement surface to enable contact with the tool engagement surface for facilitating alignment of the tool axis and the guide axis.

Abstract: A robotic surgical system includes a robotic arm comprising a plurality of links and joints, an end effector, and a mounting assembly for coupling the end effector and the robotic arm. The mounting assembly includes a robot mount associated with the robotic arm and an end effector mount associated with the end effector. The mounting assembly also includes a sterile barrier assembly including a coupling and kinematic couplers. A first lock assembly releasably secures the coupling to the robot mount and a second lock assembly releasably secures the end effector mount to the coupling. A tensioner associated with either mount is movable between a first position and a second position such that the kinematic couplers engage with, and provide a kinematic coupling between, the mounts through the sterile barrier assembly to constrain six degrees of freedom of movement between the mounts.

Abstract: A mounting system for coupling first and second surgical components. The mounting system comprises a first mounting portion associated with the first surgical component, a second mounting portion associated with the second surgical component and comprising a tensioner movable between a first position and a second position, and a sterile barrier assembly.

Abstract: A surgical instrument system for use in a surgical procedure is disclosed. The surgical instrument system may include an instrument configured to puncture the tissue of a patient and detect when the instrument has entered a lumen of the patient's body. The surgical instrument system may include one or more capacitive sensors near a tip of a needle and electrical circuitry to monitor the capacitance of the capacitive sensors. The capacitance of the capacitive sensors may change as the needle is inserted into different tissue of lumens of the patient's body, allowing for the position of the needle to be determined based on analysis of the capacitance of the capacitive sensors.
