20220008147 · 2022-01-13 ·

Devices, systems, and methods for providing a degree of freedom to a guide tube associated with a robotic surgical system. The surgical robot system may be configured to have six degrees of freedom associated with a vertical lift, rotation about a shoulder, rotation about an elbow, roll of a forearm, pitch of the end-effector, and rotation of a guide tube independent from the end-effector. The robotic surgical system allows for the proper orientation of an instrument in the guide tube along a trajectory to the operational site of a patient.

Arthroscopic devices and methods

An arthroscopic device is used with a hand piece having a motor drive with a rotating drive shaft. An elongate probe extending along a longitudinal axis and includes a proximal hub on a proximal end. The proximal hub detachably couples to the hand piece, and an openable-closeable jaw structure is disposed on a distal end of the elongate probe. A conversion mechanism carried by the hub converts a rotational motion of the motor drive shaft to a longitudinal motion of an actuator member. The actuator member drives the jaw structure between jaw-open and jaw-closed positions to resect bone and other hard tissues.

Surgical tool

A surgical tool for removing a portion of an implant is provided that includes a housing, a motor contained within the housing and coupled to the housing, and an output shaft having a distal end and a proximal end opposite the distal end, wherein the proximal end is coupled to the motor and the distal end has an opening configured to rotateably engage an implant. The surgical tool further includes a counter-torque sleeve extending around the output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the housing and the distal end is configured to couple to the implant relative to the counter-torque sleeve. Upon a rotational force to the implant, the forces transmitted by the output shaft and the counter-torque sleeve are balanced by the coupling of the output shaft and counter-torque sleeve through the housing.

Adjustable drill guide and methods of use thereof

Drill guide assemblies are adjustable for proper alignment of drill holes in the glenoid with the drill holes in the coracoid during a Latarjet procedure. The drill guide has an aimer arm extending from the body of the drill guide which has a fixed angle with respect to a drill sleeve inserted through the guide. The aimer arm can move up or down relative to the drill sleeve while maintaining the fixed angle relative to the drill sleeve by actuation of a translation member on the body.

11166829 · 2021-11-09 · ·

A cutting device is provided that includes an expandable tube having a base and a hollow interior for receiving the implant therein. The expandable tube includes cutting segments extending from the base and terminating to form a distal end of the expandable tube. At least one of the cutting segments has a cutting end with cutting teeth at the distal end of the expandable tube. Spring shaped sections are provided that extend the cutting segments. A method for removing an implant from a target bone is also provided based on the cutting device. A system for removing material directly surrounding an outer surface of an implant in an intramedullary canal of a target bone is also provided based on the cutting device and a sheath. A retractable opening is formed of leaflets at a distal end of the sheath, and a proximal end opposite the distal end.

Method for closed loop control of motor velocity of a surgical stapling and cutting instrument

A control circuit usable with a surgical instrument including a displacement member, a motor configured to translate the displacement member, and a position sensor configured to monitor a position of the displacement member is provided. The control circuit includes logic configured to provide a motor set point velocity to the motor and display a first indicia on a display indicative of the motor set point velocity.

NAVIGATED SURGICAL SYSTEM INCLUDING OVERRIDE OPTION

A surgical system including a surgical tool and a navigation system for tracking the position of the surgical tool. The surgical tool comprising a housing including a variable speed motor and control module disposed within the housing. The navigation system comprising a navigation console in communication with the control module of the surgical tool, the navigation console may be configured to communicate instructions to the control module of the surgical tool based on the position of the surgical tool relative to a defined zone. The navigation console may be configured to deactivate the surgical tool based on the position of the surgical tool relative to the defined zone. The navigation console may also be configured to provide a user-selectable override option to allow continued operation of the surgical tool within the defined zone.

11786259 · 2023-10-17 · ·

Systems and methods for ultrasonically-assisted placement of orthopedic implants is described herein. An example method may comprise delivering ultrasonic energy to a surgical instrument such as a screw driver, Jamshidi needle, awl, probe, or tap that is in contact with the bone region targeted for removal and/or being prepared for implant placement. The method may further comprise delivering the ultrasonic energy via a probe passed through a cannulated surgical instrument and/or implant. An example system may comprise an ultrasonic generator coupled to a transducer, a probe or surgical instrument coupled to the transducer, a cannulated surgical instrument that allows passage of the probe, and a computing device configured to control the ultrasonic generator and take input from the user.

TECHNIQUES FOR ADAPTIVE CONTROL OF MOTOR VELOCITY OF A SURGICAL STAPLING AND CUTTING INSTRUMENT

A method of controlling motor velocity in a surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer coupled to the control circuit. The method includes receiving a first position of a displacement member from a position sensor, starting a timer, advancing the displacement member to a second position by setting a motor velocity to a first velocity, receiving the second positon from the position sensor, stopping the timer when the displacement member reaches the second position, receiving elapsed time from the timer, wherein the elapsed time is the time taken by the displacement to move from the first position to the second positon, and controlling, by the control circuit, velocity of the motor based on the elapsed time.

Burring devices, systems, and methods
