System and method for controlling a manipulator in response to backdrive forces
A system and method for controlling a manipulator are provided. A manipulator controller measures an actual torque and calculates an expected torque for at least one joint motor of the manipulator. The manipulator controller computes a backdrive force for the at least one joint motor based on the actual torque and expected torque. A surgical tool of the manipulator is modeled as a virtual rigid body. The manipulator controller computes a total force or torque to apply to the virtual rigid body based on the backdrive force. The manipulator controller determines a target position of the surgical instrument based on the total force or torque and commands positioning of the joint motors to advance the surgical instrument to the target position.
BONE PLATE FOR ELASTIC OSTEOSYNTHESIS
Embodiments provide a method and device for plate osteosynthesis of a bone fracture that allows angle-stable fixation of the bone fracture, while permitting elastic axial motion at the fracture site in a controlled, symmetric manner to stimulate fracture healing. Embodiments pertain to a bone plate having an outer surface and a bone-facing surface. The bone plate incorporating internal sliding elements containing a threaded receiving hole for bone screws that have a correspondingly threaded screw head. The sliding elements undergo controlled displacement parallel to the longitudinal axis of the plate but are substantially constrained against displacement perpendicular to the longitudinal axis of the plate. The bone screws with threaded heads may be rigidly fixed to the threaded receiving holes in the sliding elements without compressing the bone plate onto the hone surface. Sliding elements are elastically suspended inside the bone plate and undergo dynamic motion.
Wrist joint performance measuring device
A wrist joint performance measuring device includes a base having a seat and two positioning arms on two sides of the seat. A switching device is pivotably mounted to the base. A forearm support is connected to the switching device. A measurement device includes a pivotal seat, a torque meter, a first handle, and a second handle. The pivotal seat is pivotably connected to the forearm support. The torque meter is mounted to the pivotal seat. The first handle or the second handle is connected to a force receiving end of the torque meter. The forearm support and the measurement device are movable by the switching device to one of the two positioning arms and are positioned by the one of the two positioning arms.
Notched apparatus for guidance of an insertable instrument along an axis during spinal surgery
Described herein is a surgical instrument guide for use with a robotic surgical system, for example, during spinal surgery. In certain embodiments, the guide is attached to or is part of an end effector of a robotic arm, and provides a rigid structure that allows for precise preparation of patient tissue (e.g., preparation of a pedicle) by drilling, tapping, or other manipulation, as well as precise placement of a screw in a drilled hole or affixation of a prosthetic or implant in a prepared patient situation.
Robotic System and Method for Reorienting a Surgical Instrument Moving Along a Tool Path
Robotic system and method for positioning an energy applicator extending from a surgical instrument. The robotic system includes a surgical manipulator operable in a manual mode or a semi-autonomous mode. The surgical manipulator moves the energy applicator along a tool path in the semi-autonomous mode and reorients the surgical instrument.
SURGICAL DEVICE WITH SMART BIT RECOGNITION COLLET ASSEMBLY TO SET A DESIRED APPLICATION MODE
A surgical device of a drill/driver with bit recognition to set a desired application mode and a method of utilization thereof is provided. Various operating modes of the drill/driver are automatically set by a sensor which recognizes the bit applied to the drill/driver. A method of utilizing the drill/driver allows the drill driver to apply surgical screws at very high speeds while automatically preventing excessive torque levels that would strip out the surgical screw from the patient's bone.
TORQUE-BASED CATHETER ARTICULATION
A robotic surgical system configured for the articulation of a catheter comprises an input device, a control computer, and an instrument driver having at least one motor for displacing the pull-wire of a steerable catheter wherein the control computer is configured to determine the desired motor torque or tension of the pull-wire of a catheter based on user manipulation of the input device. The control computer is configured to output the desired motor torque or tension of the pull-wire to the instrument driver, whereby at least one motor of the instrument driver implements the desired motor torque to cause the desired pull-wire tension to articulate the distal tip of the catheter. The present embodiment further contemplates a robotic surgical method for the articulation of a steerable catheter wherein an input device is manipulated to communicate a desired catheter position to a control computer and motor torque commands are outputted to an instrument driver. The robotic system may further comprise a torque sensor. The robotic system may also incorporate closed loop feedback in which data from the torque measuring device is used to ensure that the torque in the motor or tension in the pull-wire closely matches the motor torque command from the control computer.
POWERED MEDICAL DEVICE INCLUDING MEASUREMENT OF CLOSURE STATE OF JAWS
A powered surgical instrument including an end effector, which includes jaws that are configured to transition between various closure states. The surgical instrument includes a sensor configured to measure the closure state of the jaws and a display configured to display information indicative to the detected closure state. The surgical instrument further includes a firing member movable between a first position and a second position to transition the end effector between the plurality of closure states and a motor configured to drive the firing member between the first position and the second position.
DISPLAY ARRANGEMENTS FOR ROBOT-ASSISTED SURGICAL PLATFORMS
Various surgical systems are disclosed. A surgical system comprises a robotic tool, a robot control system, a surgical instrument, and a surgical hub. The robot control system comprises a control console and a control unit in signal communication with the control console and the robotic tool. The surgical hub comprises a display. The surgical hub is in signal communication with the robot control system. The surgical hub is configured to detect the surgical instrument and represent the surgical instrument on the display.
METHOD OF HUB COMMUNICATION WITH SURGICAL INSTRUMENT SYSTEMS
A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.
