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.

An electrosurgical device includes jaw members, a thermal cutting element coupled to one of the jaw members. When the jaw members are in an approximated position, power is delivered to the thermal cutting element to maintain the temperature of the thermal cutting element at an operating temperature for cutting sealed tissue grasped between the jaw members. When the jaw members are in the spaced apart position, power is delivered to the thermal cutting element to maintain the temperature of the thermal cutting element at a standby setpoint temperature. In response to a determination of contact between tissue and the thermal cutting element when the jaw members are in the spaced apart position, power is delivered to the thermal cutting element to increase the temperature of the thermal cutting element from the standby setpoint temperature to a cutting setpoint temperature for dissecting tissue.

A measuring method for optically determining a distance (z) of a surface located in a medium from an end of an optical waveguide is described and has the following steps: emitting electromagnetic measuring radiation of a first wavelength (λ1) and of a second wavelength (λ2) from the end of the waveguide towards the surface, wherein the medium more strongly absorbs the electromagnetic measuring radiation of the second wavelength (λ2) than the electromagnetic measuring radiation of the first wavelength (λ1); measuring a first reflection signal (I.sub.1) of the electromagnetic measuring radiation of the first wavelength (λ1) reflected from the surface, and measuring a second reflection signal (I.sub.2) of the electromagnetic measuring radiation of the second wavelength (λ2) reflected from the surface, and determining the distance (z) from a ratio (I.sub.2:I.sub.1) of the second and the first reflection signal. Furthermore, a measuring device and a laser lithotripsy device are described.

A method of operating a modular surgical system including a control module, a first surgical module, and a second surgical module is disclosed.

Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.
