Abstract: An apparatus including a tendon-driven device such as an endoscope comprising a bendable body, a tendon attached to and extending a length of said body, and an actuator that will actuate said tendon based on a control signal from a controller. The controller is configured to send said control signal to said actuator and comprises a forward-kinematic-mapping unit that estimates an angular displacement, wherein the kinematic-mapping unit is configured for: providing a tension value of the tendon to obtain a desired angular displacement wherein the tension has a nonlinear relationship with the desired angular displacement based on information of friction where the tension is greater that would be calculated without including the effect of friction. The friction coefficient may be determined as it changes over time.
Abstract translation: 一种包括腱驱动装置的装置，例如内窥镜，其包括可弯曲本体，附接并延伸所述主体的长度的腱，以及将基于来自控制器的控制信号致动所述腱的致动器。 控制器被配置为将所述控制信号发送到所述致动器并且包括估计角位移的前向运动学映射单元，其中所述运动映射单元被配置为：提供所述腱的张力值以获得期望的角位移 其中所述张力与基于摩擦信息的所需角位移具有非线性关系，其中所述张力大于将被计算的张力，而不包括摩擦的影响。 摩擦系数随着时间的推移可以确定。

IPC: A61B34/00
Abstract: The present application relates to a flexible manipulator including at least one flexible member (bend) controlled by an input device in the form of a joystick. Specifically, to prevent the flexible manipulator inserted into a narrow space from contacting surrounding objects, the flexible manipulator according to the present invention is configured to maintain the shape when the operator releases the joystick. However, when the flexible manipulator is shaped to be at a target position and subsequently needs to be returned to the original shape, the operator manipulates the joystick using complicated and time consuming manipulation techniques. A control device in communication with the flexible manipulator is configured to allow the operator to select an input method for maintaining the shape of the flexible manipulator after the joystick is released. In addition, an input method for returning the flexible manipulator to the original shape may be selected. This enables the operator to use an appropriate input method in accordance with the purpose of a medical procedure.
