With the existing capabilities of the ISU, surgeons have machine vision-powered control of the camera via responses to commands and identification of some objects and sites in the surgical field.

Surgeons can also alter the visualised field of view by moving their instruments.

The expanded ISU features offer advanced capabilities, such as 3D measurement, digital tagging and enhancement of images. In addition, more camera control is enabled through the use of real-time data from anatomical structures during surgical procedures.

Asensus noted that this marks the first clinical availability of these augmented intelligence features in soft-tissue abdominal surgery.

Asensus Surgical president and CEO Anthony Fernando said: “The addition of these pioneering digital capabilities on our existing surgical platform provides real-time intraoperative digital tools to surgeons and underscores our commitment to delivering our vision for Performance-Guided Surgery.”

The new 3D measurement capability can be leveraged by surgeons to mark points on the tissue floor and throughout the abdominal cavity to obtain precise, real-time measurements of the distances between the marked points.

This provides an alternative option to the estimations or sterile measuring tapes used during conventional minimally invasive surgery.

Meanwhile, digital tagging facilitates notes on the live surgical camera view, allowing real-time guidance and planning.

Image enhancement regulates the surgical scene’s brightness and contrast to deliver a clear and reliable image, as well as enabling the acquisition of quality video.

Based on current instrument-based camera control techniques, the newly enhanced camera control feature guides the alignment of the camera depending on the tracked location of various instruments in the surgical scene.

Asensus Surgical expects the newly added features to support surgeons across various specialities and procedures.
