Abstract: A computer-implemented method of assessing operator behavior during a medical procedure involving medical equipment, is provided. The method includes: receiving operator interaction data representing operator interactions with the medical equipment during the medical procedure; inputting the operator interaction data into a machine-learning model; and outputting a characteristic of the operator behavior based on a position of a latent space encoding of the operator interaction data generated by the machine-learning model, with respect to a distribution of latent space encodings of training data representing operator interactions with the medical equipment having known characteristics of the operator behavior.

Abstract: A surgical suction device is disclosed that includes a suction tube having a first longitudinal axis, a proximal opening, and a distal opening; a guide tube that is substantially coextensive with and parallel to the suction tube, and has a second longitudinal axis, a proximal opening, and a distal opening; a stylet having a proximal end and a distal end; and a junction point having a proximal opening and a distal opening; wherein the stylet is disposed along the second longitudinal axis and encircled by the guide tube, and urging the stylet through the guide tube along the second longitudinal axis through the junction conduit translates the distal end of the stylet to the distal opening of the junction point. The guide tube may effectively cut the length of the handle member in half.

Abstract: A self-cleaning tissue removal instrument is disclosed and described herein. The self-cleaning tissue removal instrument generally comprising: a handle operably coupled with a proximal end of a rail portion; a jaw portion operably coupled to a distal end of the rail portion, a longitudinal axis running along the proximal portion to the distal portion of the self-cleaning tissue removal instrument; wherein the jaw portion is moved from an open position to a closed position by operation of the rail portion translating along the longitudinal axis of the self-cleaning tissue removal instrument, and the jaw portion clamps down and removes tissue in the closed position; and a cleaning mechanism operably coupled with the rail portion, whereby the cleaning mechanism disengages any tissue attached to the jaw portion when the jaw portion longitudinally translates to the open position.
