More Information
Summary:The present disclosure relates generally to a simplified transesophageal echocardiography (TEE) probe mid-handle assembly for actuating the pull cables that control the flexion of the distal end of the gastroscope portion of a TEE probe. The assembly includes a containment frame, two control wheels, two coaxial shafts each coupled to one of the control wheels, with an elongated flexible member wrapped around each shaft. The elongated flexible members may be friction belts, timing ladders, pulley cables, timing belts, or drive tapes to translate the rotational motion of the control wheels into linear motion of the gastroscope pull cables. The assembly may also include a brake switch that, when engaged, applies a resistance to rotation of the shafts and control wheels. In some embodiments, control wheels and containment frame are made of molded plastic, and the elongated flexible members are made of elastomeric compounds moulded over Kevlar, nylon, or metal reinforcement members to reduce stretch and increase life.
