ADAPTIVE RETRACTION FORCE CONTROL

Smart overview of the Invention

The surgical system integrates a processor, a surgical cutting instrument, and a retraction instrument to enhance tissue cutting and retraction during surgery. The processor identifies surgical tasks, assesses nearby structures, and calculates appropriate retraction force direction and intensity. This calculated force guides the retraction instrument, allowing precise tissue retraction and cutting, minimizing potential harm to surrounding tissues.

Functionality

The system evaluates the movement and speed of the cutting instrument, predicting tissue response and adjusting retraction force accordingly. By considering the proximity of structures, it avoids injury by modifying the cutting instrument's movements based on potential harm indicators. Tension ranges and force limits are established to prevent tissue damage, ensuring retraction forces do not exceed safe thresholds.

Imaging and Adaptation

Imaging technology helps the system identify tissue planes and critical structures, adjusting retraction and dissection forces to minimize injury risks, especially in scarred or remodeled tissues. The system modifies control signals based on these identifications, facilitating safe navigation through the surgical area.

System Architecture

The surgical system may include various components like a surgical hub, computing devices, and cloud computing systems. It communicates with remote servers to process data in real-time, using cellular and wireless protocols. This cloud-based approach leverages shared computing resources for efficient data handling and analytics, enhancing surgical procedures.

Sensing and Communication

Sensing systems integrated into the surgical hub measure biomarkers using various sensors and protocols. These systems monitor physiological aspects of patients and surgeons, aiding in surgical planning and execution. Data is transmitted through RF protocols like Bluetooth and Wi-Fi, enabling real-time monitoring and adjustments to improve surgical outcomes.
