Surgical Robotic Access Port Length Adaptation

The system dynamically adapts the access port length selection based on real-time torque measurements from patient tissue interaction. The controller adjusts the recommended port length according to the measured torque values, transforming a static system into a dynamic one that responds to patient-specific conditions.

The system changes the parameter of access port length based on torque measurements. By measuring torque at different joint positions and comparing it to threshold values, the system determines appropriate port length parameters (standard or extended) to accommodate different patient habitus.

The system implements feedback by continuously measuring torque at robotic arm joints during patient interaction and using this information to automatically determine the appropriate access port length. The measured torque values are fed back to the controller, which compares them against threshold values to make port length recommendations.

The system replaces manual assessment of patient habitus with an automated mechanical measurement system using torque sensors. Instead of relying on visual inspection or manual measurement, the system uses torque measurements from the robotic arm joints to objectively determine the appropriate port length.

The system takes preliminary anti-action by disabling instrument operation before potential harm can occur. The controller prevents instrument activation until the surgeon confirms the recommended port length is appropriate, blocking potentially harmful operations in advance while maintaining safety.

The system performs preliminary action by providing port length recommendations and requiring confirmation before instrument operation begins. This preliminary step ensures the correct port length is selected before the surgical procedure commences, preventing errors while maintaining operational efficiency through streamlined confirmation processes.
