摘要：
A compliant surgical device such as a flexible entry guide employs tendons to operate or steer the device and attaches asymmetric or constant force spring systems to control tension in the tendons. As a result, the surgical device can be compliant and respond to external forces during a surgical procedure without rapidly springing back or otherwise causing a reaction that damages tissue. The compliance also permits manual positioning or shaping of the device during or before insertion for a surgical procedure without damaging the tendons or connections of the tendons within the device or to a backend mechanism.
