    摘要: A tension mechanism for a robotically-controlled medical device measures the tension applied to an actuation tendon to provide feedback to a robotic controller. In one embodiment, the device comprises an elongated instrument, an elongated member, and a base. The elongated member is coupled to the distal end of the elongated instrument, configured to actuate the distal end of the elongated instrument in response to tension in the elongated member. The base is located at the proximal end of the elongated instrument, and comprises a first redirect surface that redirects the elongated member. The first redirect surface is coupled to a lever element that is configured to exert a reactive force on a sensor in response to tension in the elongated member.

    摘要: An Active Ankle Foot Orthosis (AAFO) is provided where the impedance of an orthotic joint is modulated throughout the walking cycle to treat ankle foot gait pathology, such as drop foot gait. During controlled plantar flexion, a biomimetic torsional spring control is applied where orthotic joint stiffness is actively adjusted to minimize forefoot collisions with the ground. Throughout late stance, joint impedance is minimized so as not to impede powered plantar flexion movements, and during the swing phase, a torsional spring-damper (PD) control lifts the foot to provide toe clearance. To assess the clinical effects of variable-impedance control, kinetic and kinematic gait data were collected on two drop foot participants wearing the AAFO. It has been found that actively adjusting joint impedance reduces the occurrence of slap foot, allows greater powered plantar flexion, and provides for less kinematic difference during swing when compared to normals.
