Current robotic surgical systems require extensive manual control and monitoring, with surgeons spending up to 30% of procedure time managing tool transitions and camera positioning. These inefficiencies compound across thousands of procedures annually, impacting both surgical team workflow and operating room utilization.

The core challenge lies in automating routine surgical tasks while maintaining absolute precision and safety in a dynamic operating environment where split-second decisions have critical consequences.

This page brings together solutions from recent research—including AI-powered tissue recognition systems, automated surgical state detection, machine learning for instrument tracking, and intelligent workflow optimization. These and other approaches focus on enhancing surgical efficiency while maintaining surgeon control over critical decision points during procedures.

1. Network-Based Robotic Surgery System with Timestamp-Synchronized Input Signal Transmission

Sovato Health, Inc., 2025
