Drop detection of ungrounded master controller for a surgical robot

Disclosed herein are methods to detect a free-falling or other non-surgical motions of the user interface device (UID) of a surgical robotic system so that the surgical robotic system may pause the robotic arm controlled by the UID to prevent the robotic arm from mimicking the unintentional movement of the UID. Contact sensors embedded in the UID may be used to detect conditions indicating that a user does not possess full control of the UID. After determining that the user does not have full control of the UID, the UID may detect if the UID is experiencing non-surgical motions using motion sensors such as inertial sensors. By conditioning analysis of the data from the motion sensors by the initial determination that the UID is not being held based on the contact sensors, the method increases the robustness of the detection of non-surgical motions and reduces the probability of false positives.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. A tool driver is coupled to a distal end of a robotic arm and includes a roll drive disk driven by a rotary motor. One or more processors are configured to detect an attachment of a surgical tool to the tool driver. The surgical tool includes a roll tool disk to be engaged with the roll drive disk of the tool driver, actuate of the roll drive disk through the rotary motor, determine that a measured torque of the rotary motor exceeds a preset torque threshold for a preset period of time since the actuation, and report a successful engagement between the roll drive disk and the roll tool disk.

MECHANICAL DEPLOYMENT DEVICE FOR HIP ALL-SUTURE ANCHOR
20230210513 · 2023-07-06 · ·

A deployment device for an all suture anchor having a braided anchor and a suture filament extending through the braided anchor. A fork extends longitudinally through the body of the device and is moveable between an extended position and a withdrawn position to position and then release the braided anchor. A ratchet wheel drives a spool coupled to the ratchet wheel by a frangible link to wind up the suture filament to deploy the braided anchor. When sufficient tension is achieved to fully deploy the braided anchor, the frangible link will break, thereby releasing the suture filament to leave the deployed braided anchor in place with the suture filament extending from the pilot hole. All operations are accomplished by one lever that selectively withdraws the fork, rotates the ratchet wheel, and then allows release of the filament with the use of just a single hand.

Constraint mechanisms, systems, and methods

A tool includes a transmission mechanism, a shaft rotatable relative to the transmission mechanism, and a stop mechanism associated with the shaft, the stop mechanism being transitionable between a first state and a second state. In the first state, the shaft is free to rotate in a first direction and in a second direction opposite to the first direction. In the second state, the shaft is constrained from rotating in one of the first direction or the second direction by a defined first endpoint of a range of rotational motion of the shaft. Devices and methods relate to rotation stop mechanisms.
