VARIABLE RESPONSE MOTOR CONTROL ALGORITHM FOR POWERED SURGICAL STAPLER
An apparatus includes an end effector, a motor, and a processing unit. The processing unit is configured to activate the motor to distally advance a firing member within a body of the end effector. The processing unit is further configured to detect an initiation condition. In response to detecting the initiation condition, the processing unit is configured to activate an algorithmic bumping mode. The bumping mode includes activating the motor to advance the firing member distally with a first plurality starting and stopping motions at a first rate and a first power level. The bumping mode further includes activating the motor to retract the firing member proximally with a second plurality of starting and stopping motions at a second rate and a second power level. The first rate is different than the second rate. The first power level is different than the second power level.
END EFFECTOR DRIVE MECHANISMS FOR SURGICAL INSTRUMENTS SUCH AS FOR USE IN ROBOTIC SURGICAL SYSTEMS
A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is configured to move the jaw members and is configured to operably couple to a torque sensor that measures the torque of the input during rotation thereof. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the movement of the jaw members. A housing having a lever operably coupled thereto, houses components therein configured to operably connect to the input such that movement of the lever correlates to movement of the jaw members. The components are configured to regulate the resistance of the lever in response to the feedback from the torque sensor.
EVALUATION OF CALIBRATION FOR SURGICAL TOOL
The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. An example computer-implemented method for evaluating calibrations of a surgical tool includes fixating a joint of the surgical tool at a first angle, the joint being driven by an actuator, measuring an actuator position corresponding to the first angle, accessing a calibrated offset corresponding to the first angle, determining an expected joint angle based on the measured actuator position and the calibrated offset, and reporting a first difference between the expected joint angle and the first angle.
Method of hub communication, processing, display, and cloud analytics
A method of displaying an operational parameter of a surgical system is disclosed. The method includes receiving, by a cloud computing system of the surgical system, first usage data, from a first subset of surgical hubs of the surgical system; receiving, by the cloud computing system, second usage data, from a second subset of surgical hubs of the surgical system; analyzing, by the cloud computing system, the first and the second usage data to correlate the first and the second usage data with surgical outcome data; determining, by the cloud computing system, based on the correlation, a recommended medical resource usage configuration; and displaying, on respective displays on the first and the second subset of surgical hubs, indications of the recommended medical resource usage configuration.
ACTIVATION OF ENERGY DEVICES
Various systems and methods for controlling the activation of energy surgical instruments are disclosed. An advance energy surgical instrument, such an electrosurgical instrument or an ultrasonic surgical instrument, can include one or more sensor assemblies for detecting the state or position of the end effector, arm, or other components of the surgical instrument. A control circuit can be configured to control the activation of the surgical instrument according to the state or position of the components of the surgical instrument.
Torsional deployment detection of a vascular therapy
A torque detection vascular therapy system employing a vascular therapy device (101) and a torque detection controller (130). The vascular therapy device (101) is operable to be transitioned from a pre-deployed state to a post-deployed state, and includes a matrix of imageable markers representative of a geometry of the vascular therapy device (101). The torque detection controller (130) controls a detection of a non-torsional deployment or a torsional deployment of the vascular therapy device (101) subsequent to a transition of the vascular therapy device (101) from the pre-deployed state to the post-deployed state by deriving a vector indication of the non-torsional deployment or the torsional deployment of the vascular therapy device (101) from a matrix orientation similarity or a matrix orientation dissimilarity between a baseline device geometry of the vascular therapy device (101) represented by the matrix of the imageable markers and an imaged device geometry of the vascular therapy device (101) represented by the matrix of imageable markers.
Intelligent holding arm for head surgery, with touch-sensitive operation
A holding arm for medical purposes, in particular for holding surgical mechatronic assistance systems and/or surgical instruments, includes a proximal end for attaching the holding arm to a base and a distal end for receiving a surgical mechatronic assistance system and/or surgical instrument; at least one first and one second arm segment, wherein the first arm segment is connected to a first joint and the second arm segment is connected to a second joint, wherein each joint is releasable and lockable. An operating unit is provided for bringing the holding arm into a desired pose, wherein the operating unit is adapted to release the associated joint upon contact between an operator and one of the first and second arm segments. A corresponding method is also provided.
Set screw sensor placement
A load sensing assembly for a spinal implant includes a set screw having a central opening that extends from a first end of the set screw toward a second end of the set screw. The second end of the set screw is configured to engage with an anchoring member. The load sensing assembly includes an antenna, an integrated circuit in communication with the antenna, where the integrated circuit is positioned within the central opening of the set screw, and a strain gauge in connection with the integrated circuit. The strain gauge is located within the central opening of the set screw in proximity to the second end of the set screw.
Electrosurgical instruments with electrodes having variable energy densities
An electrosurgical instrument comprising an end effector is disclosed. The end effector comprises a first jaw and a second jaw. At least one of the first jaw and the second jaw is movable to transition the end effector from an open configuration to a closed configuration to grasp tissue therebetween. The second jaw comprises linear portions cooperating to form an angular profile and a treatment surface comprising segments extending along the angular profile. The segments comprise different geometries and different conductivities. The segments are configured to produce variable energy densities along the treatment surface.
