Surgical Screwdriver

摘要

Various embodiments include a device for driving a fastener into tissue, including a handle having a first and second end. A shank extends from the first end of the handle and terminates in a head. An inertial measurement unit (“IMU”) is disposed at the second end of the handle. At least one torque sensor is incorporated in the device. At least one of an indicator or a transmitter is operably coupled to the IMU and the torque sensor. A method of driving a fastener into a tissue with a driver includes recording a previous state and a current state, and using the previous state and current state to predict mechanical properties of the tissue and the optimal torque to be applied. In various embodiment the device predicts a future state of the fastener. The driver notifies the user if the optimal torque has been reached or whether another state has been detected.

主权项

1. A device for driving a fastener into tissue, the device comprising:
a handle having a first end and a second end; a shank extending from the first end of the handle and terminating in a head; one or more sensors; an output device; and a processor, in which the processor executes instructions to:
receive a first set of readings from the one or more sensors during a first interval when the fastener is receding from the tissue; andcause the output device to output a first signal indicative of the first set of readings.
