SAIS is a surgical AI system that decodes surgical activity based exclusively on surgical videos. This system was first introduced in a 2023 Nature Biomedical Engineering paper.
SAIS has the ability to decode the following elements of surgery:
- surgical steps (e.g., dissection vs. suturing)
- suturing sub-phases (e.g., needle handling vs. needle driving vs. needle withdrawal)
- four distinct suturing gestures
- six distinct tissue dissection gestures
- needle handling binary skill level
- needle driving binary skill level
To demonstrate the utility of SAIS, we have developed an interface that allows users to upload a brief surgical video (on the order of 10-20 seconds) and identify:
- six distinct tissue dissection gestures
- binary skill level of suturing activity
