Filed:

Mar 26, 2021

Appl. No.:

17/213518

Inventors:

- Guaynabo PR, US

Joshua P. Morgan - Benton KY, US

International Classification:

A61B 90/50
A61B 17/34

Abstract:

A gyroscopic stabilizer configured to stabilize a surgical instrument relative to a patient includes a frame having a central axis and a hub configured to releasably couple with the surgical instrument. A first gyroscope assembly is coupled with a first frame portion and a second gyroscope assembly is coupled with a second frame portion. Each gyroscope assembly includes a gimbal pivotably coupled with the respective frame portion about a precession axis, a motor, and a rotor rotatably coupled with the motor about a spin axis perpendicular to the respective precession axis. Each gyroscope assembly is operable generate a torque in a torque plane that contains the respective spin axis and the respective precession axis. The torques are configured to resist rotation of the gyroscopic stabilizer relative to the patient about respective device axes that are perpendicular to the central axis and to one another.

Abstract:

An exemplary system and method for homing a surgical tool are provided. In general, a surgical tool can include an end effector, an elongate shaft, and a wrist that couples the end effector to a distal end of the shaft can be configured to facilitate movement of the end effector relative to the shaft. The surgical tool can be coupled to a robotic surgical system featuring an imaging device and a processor. Through the use of closed-loop feedback and machine vision techniques, the end effector can be calibrated into a home position to ensure precise and accurate movement of the end effector when in use by a surgeon.
