An orthopedic implantation operation system includes a power drill mechanism and a linear advancing mechanism. The linear advancing mechanism includes a linear motor; the linear motor is connected with the power drill mechanism to drive the power drill mechanism to make a linear reciprocating motion to realize the advancement motion of the surgical tool. The present invention provides the driving force of the linear reciprocating motion of the power drill mechanism through a linear advancing mechanism, and combines with a power drill mechanism to clamp surgical tools such as a guide pin, reamer, tap and a vertebral pedicle screw, etc. so as to realize the operation of orthopedic implantation. Compared with artificial orthopedic implantation operations, the operation is stable, the impact on the human body is small, and the operation efficiency and accuracy of orthopedic implantation operations are higher, avoiding accidental injuries that may be caused by manual orthopedic implantation.

Systems and methods for controlling and navigating robots in a surgical environment are disclosed. The systems and methods described herein provide techniques to adjust the location of a robot, such as a surgical robot, in response to detecting movement of a patient using image-based tracking techniques. Techniques are provided that enables a robot control system to adjust a position of a surgical robot in real-time or near real-time in response to measurements from sensors coupled to the robot or a patient in a surgical environment. Techniques for initiating a collaborative control status of a surgical robot in response to detecting image alignment errors, sensor measurements, or other conditions are disclosed.

Co-manipulation robotic systems are described herein that may be used for assisting with laparoscopic surgical procedures. The co-manipulation robotic systems allow a surgeon to use commercially-available surgical tools while providing benefits associated with surgical robotics. Advantageously, the surgical tools may be seamlessly coupled to the robot arms using a disposable coupler while the reusable portions of the robot arm remain in a sterile drape. Further, the co-manipulation robotic system may operate in multiple modes to enhance usability and safety, while allowing the surgeon to position the instrument directly with the instrument handle and further maintain the desired position of the instrument using the robot arm.

Techniques for control of an instrument include a device having an actuator. To perform an operation with an instrument coupled to the actuator, the instrument is operated according to a state machine by: transitioning the instrument from a gripped state to a clamped state in response to receiving a clamp command; transitioning the instrument from the clamped state to a firing state in response to receiving a fire command; transitioning the instrument from the firing state to a pause state in response to detecting a stall in the actuator used to actuate the instrument; transitioning the instrument from the pause state to a stop firing state in response to a pause limit being reached; and transitioning the instrument from the pause state to the firing state in response to the actuator beginning to move again or after a first predetermined period of time has elapsed since entering the pause state.

[Object] To enable further suppression of the movement amount of an arm section when switching states.

[Solution] There is provided a control apparatus configured to execute a current tracking control on a basis of a measurement value of a torque sensor of an actuator provided in at least one of multiple joint sections included in an arm section of a medical support arm apparatus, the current tracking control causing a motor of the actuator to output torque by which a position and an attitude of the arm section are maintained, and switch a first state in which the motor is driven in accordance with a predetermined control method, and a second state in which the joint section is locked using a brake of the actuator.

A medical manipulator is improved in terms of invasiveness into a body tissue and an emergency avoidance difficulty. The medical manipulator includes a driving unit including a vibration-type actuator including a vibrating unit that generates a vibration wave, a moving unit movable relative to the vibrating unit in response to receiving the vibration wave, and a pressure application unit configured to apply a pressure between the vibrating unit and the moving unit. The medical manipulator further includes a manipulator unit connected to the driving unit and configured to be movable by being driven by the driving unit, a supporting unit that supports the driving unit and the manipulator unit, a driving circuit connected to the vibrating unit and configured to apply an AC voltage to the vibrating unit, and a torque control unit configured to control a holding torque with which the moving unit is held by the vibrating unit.

A device can be provided that includes a bone plate having an upper surface and a bone-facing surface, wherein the bone plate includes one or more openings extending through the bone plate from the upper surface to the bone-facing surface, and one or more sliding elements each including a fastener receiving hole. The one or more openings can at least partially surround a periphery of one of the receiving holes. Further, the one or more openings can be at least partially filled with an elastomer to support elastic suspension of the one or more sliding elements in the bone plate, thereby enabling relative displacement between the one or more sliding elements and the bone plate. At least one sensor can also be provided that is operable to assess a dynamic parameter of one of the one or more sliding elements within the bone plate.

A method for intraoperatively measuring joint contact mechanics of a patient's joint is provided. The method includes inserting a sensor between first and second bones of a joint. Then a predetermined force is applied to one of the first and second bones. Afterwards, contact mechanics such as, contact stresses, contact areas and/or forces are measured between the first and second bones in response to the applied predetermined force.

A system and method for coordinated and controlled abdominal gas insufflation includes clamp configured to engage an abdominal wall. A needle advancement control is configured to receive a needle and advance the needle toward the clamp to extend into a portion of the abdomen. A feedback device is configured to monitor the needle as it is advanced into the portion of the abdomen of the subject and provide feedback indicating that the needle has pierced the portion the abdomen.

A computer-assisted surgery system may have a robotic arm including a surgical tool and a processor communicatively connected to the robotic aim. The processor may be configured to receive, from a neural monitor, a signal indicative of a distance between the surgical tool and a portion of a patient's anatomy including nervous tissue. The processor may be further configured to generate a command for altering a degree to which the robotic aim resists movement based on the signal received from the neural monitor; and send the command to the robotic arm.
