Solution Overview
Problem
Current surgical robotic systems lack an effective method to indicate the state of patient anatomy during surgical procedures, particularly in minimally invasive surgeries where direct visualization is limited.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If minimally invasive surgery is performed using endoscope and robotic arm, then patient trauma is reduced and recovery is accelerated, but direct visualization of surgical site is limited and anatomical state assessment becomes difficult
Solution Approach 1:
The patent introduces an intermediary indicator system that translates internal anatomical state changes into visible external indicators. The system uses sensors to detect physiological parameters (temperature, pressure, flow) and converts them into visual or tactile signals that surgeons can observe, thereby mediating between the minimally invasive approach and the need for information about surgical site conditions
Solution Approach 2:
The patent replaces direct mechanical visualization (surgeon's eyes directly observing the surgical site) with an electronic sensing and signaling system. Sensors detect anatomical state changes and transmit this information through electronic indicators, substituting the mechanical line-of-sight requirement with an electronic information transmission system
2Device complexity
If traditional surgical monitoring methods are used, then equipment complexity is low, but real-time detection of anatomical state changes is insufficient
Solution Approach 1:
The patent segments the monitoring function into multiple independent sensors that detect different physiological parameters (temperature, pressure, flow rate) separately. Each sensor focuses on a specific parameter, allowing for high precision measurement of individual anatomical states while keeping each sensor component relatively simple
Solution Approach 2:
The indicator system is designed to monitor multiple anatomical parameters simultaneously using a integrated platform. The system can detect temperature changes, pressure variations, and fluid flow rates through a unified sensing and display mechanism, providing multi-functional monitoring capability
3Measurement precision
If spatio-temporal analysis of video data is performed to detect anatomical changes, then measurement precision of anatomical state is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary processing of video data by pre-defining regions of interest and pre-configuring detection algorithms for specific anatomical structures. This preliminary setup allows the system to focus computational resources on critical areas, reducing real-time processing requirements while maintaining high measurement precision
Solution Approach 2:
The patent applies partial analysis by focusing computational effort only on specific pixel regions that contain anatomical structures of interest, rather than analyzing the entire video frame. This selective approach reduces processing time while maintaining precision for the critical anatomical areas being monitored

AI summary
An indicator system for a surgical robotic system for indicating a state of at least a portion of patient anatomy, the surgical robotic system comprising a robot having abase and an arm extending from the base, the arm holding an endoscope at an end of the arm distal from the base, the endoscope being configured for insertion into a body cavity of the patient for observing a surgical site internal to a body of the patient, the indicator system comprising: a receiver configured to receive video data of at least a portion of patient anatomy at the surgical site from the endoscope; and a processor configured to:detect a spatio-temporal change in a pixel region of the received video data; identify, in response to the detected spatio-temporal change, a parameter of the patient anatomy; generate a health indicator indicative of the identified parameter or indicative of a profile of the identified parameter; and output the generated health indicator.
