The present invention provides a surgical robot system which includes a workstation, a robotic arm, a scanning module, a guiding module and the like. Fast registration may be completed by means of the scanning module. The system improves the speed and accuracy of registration and shortens the period of the operation.

A robotic arm assembly includes a robotic arm and an instrument drive unit coupled to the robotic arm. The instrument drive unit is configured to provide five degrees of rotational freedom and includes a motor housing, motors supported in the motor housing and rotatable with the motor housing, and gear box assemblies coupled to the motors and configured to transmit drive power from the motors to a surgical instrument. The robotic arm may include a mounting arm that extends to an annulus for supporting a surgical port that selectively receives the surgical instrument.

[Object] To make it possible to perform gravity compensation with a more compact and lightweight configuration. [Solution] There is provided a medical support arm apparatus including: an arm section including multiple joint sections, and configured such that a medical tool is provided on a front end; an actuator at least provided in a compensated joint section that is a target of gravity compensation among the joint sections, and including a torque sensor that detects a torque acting on the compensated joint section; and a gravity compensation mechanism that imparts to the compensated joint section a compensating torque in a direction that cancels out a load torque due to a self-weight of the arm section acting on the compensated joint section.

Embodiments pertaining to a medical construct are disclosed. The medical construct may include a set screw extending along a longitudinal axis between a proximal portion and a distal portion, for example. In various embodiments, the set screw may have an outside thread form and an interior socket, for example. In various embodiments, the socket may extend parallel to the longitudinal axis and have a circular lower surface, for example. In various embodiments, a first strain gauge, a second strain gauge, a third strain gauge, a fourth strain gauge, and a fifth strain gauge may be provided. In at least some embodiments, each of the first, second, third, and fourth strain gauges may be symmetrically disposed with respect to the lower surface, for example. Additionally, in at least some embodiments, the fifth strain gauge is disposed within a center portion of the lower surface, for example.

A surgical manipulator is disclosed which includes a surgical instrument, an arm comprising a plurality of links and being configured to support and move the surgical instrument, and at least one controller. The at least one controller is configured to model the surgical instrument as a virtual rigid body. Forces and torques are applied externally to the surgical instrument. The at least one controller determines a commanded pose of the surgical instrument based on evaluation of the forces and torques and controls movement of the arm to place the surgical instrument according to the commanded pose.

Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position. The instrument may further include a stapler cartridge including an annular pin configured to be engaged by a drive member at a an axial position to create a detectable resistance for reload detection by a control unit to identify the type of stapler cartridge present in the surgical stapling instrument.

Embodiments of a system and method for surgical tracking and control are generally described herein. A system may include a robotic arm configured to allow interactive movement and controlled autonomous movement of an end effector, a cut guide mounted to the end effector of the robotic arm, the cut guide configured to guide a surgical instrument within a plane, a tracking system to determine a position and an orientation of the cut guide, and a control system to permit or prevent interactive movement or autonomous movement of the end effector.

A robotically enabled teleoperated system can include a controller and an instrument capable of manipulation by the controller. The instrument can be a medical instrument. The controller can include a handle configured for actuation by an operator. The handle can be attached to a gimbal configured to allow manipulation of the handle in multiple rotational degrees of freedom. The gimbal can include a load cell. The gimbal can be configured for impedance control. The controller can also include a positioning platform coupled to the gimbal and configured to allow manipulation of the handle in multiple positional degrees of freedom. The controller can be configured for admittance control based at least in part on an output signal of the load cell in the gimbal.

Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

Described herein is a device and method used to effectively remove volume inside a patient in various types of surgeries, such as spinal surgeries (e.g. laminotomy), neurosurgeries (various types of craniotomy), ENT surgeries (e.g. tumor removal), and orthopedic surgeries (bone removal). Robotic assistance linked with a navigation system and medical imaging it can shorten surgery time, make the surgery safer and free surgeon from doing repetitive and laborious tasks. In certain embodiments, the disclosed technology includes a surgical instrument holder for use with a robotic surgical system. In certain embodiments, the surgical instrument holder is attached to or is part of an end effector of a robotic arm, and provides a rigid structure that allows for precise removal of a target volume in a patient.
