A surgical instrument assembly includes a surgical instrument having an instrument body, an elongate member with a distal end configured to be inserted into an anatomical passageway of a patient, a sensor operable to generate a signal corresponding to a location of the elongate member, and a first electrical connector electrically coupled with the sensor. The assembly further includes a cable assembly having a cable that communicates with a processor, and a coupling that releasably couples with the instrument body. The coupling includes a coupling body having first and second lateral sides that extend parallel to one another and are configured to extend parallel to a side of the instrument body when the coupling is coupled with the instrument body. The coupling includes a second electrical connector that electrically couples with the first electrical connector to transmit the signal from the sensor proximally through the cable and toward the processor.

Embodiments described herein provide various techniques and systems for building machine-learning surgical tool presence/absence detection models for processing surgical videos and predicting whether a surgical tool is present or absent in each video frame of a surgical video. In one aspect, a process for ensuring patient safety during a laparoscopic or robotic surgery involving an energy tool is disclosed. The process can begin receiving a real-time control signal indicating an operating state of an energy tool during the surgery. Next, the process receives real-time endoscope video images of the surgery. The process simultaneously applies a machine-learning surgical tool presence/absence detection model to the real-time endoscope video images to generate real-time decisions on a location of the energy tool in the real-time endoscope video images. The process then checks the real-time control signal against the real-time decisions to identify an unsafe event and takes a proper action when an unsafe event is identified.
