Detecting endolumenal buckling of flexible instruments
First Claim
1. A method for detecting buckling of a medical instrument comprising an elongate body, the method comprising:
- directing a command to move an elongate body;
receiving sensor data generated from a first sensor placed in a first portion of the elongate body, the sensor data comprising information regarding a first measured status of the first portion of the elongate body;
determining a first expected status of the first sensor from command data useable to control a manipulator coupled to the elongate body to effect movement of the elongate body;
comparing the first measured status with the first expected status; and
responsive to the first measured status deviating from the first expected status relative to a first associated threshold, determining that the elongate body has buckled.

Abstract
A robotic system is described for determining whether a flexible instrument has buckled. The robotic system comprises a medical instrument comprising an elongate body, and further comprises a first sensor placed in a first portion of the elongate body, and a controller. A command is directed to the elongate body. The first sensor generates sensor data providing information regarding a first measured status of the portion of the elongate body. The controller receives sensor data generated from the first sensor, and compare the first measured status with a first expected status expected to be caused by the command; and responsive to the first measured status deviating from the first expected status one of more or less than a first associated threshold, determine that the elongate body has buckled.
