    Abstract: A mechanical interface for a robotic medical instrument permits engagement of the instrument and a drive system without causing movement of an actuated portion of the instrument. An instrument interface can include a symmetrical, tapered or cylinthical projection on one of a medical instrument or a drive system and a complementary bore in the other of the drive system or the medical instrument. Symmetry of the projection and the bore allows the projection to be compression fit to the bore regardless of the rotation angle of the drive system relative to the medical instrument.

    Abstract: A shaft for a surgical instrument comprises an outer tube having a proximal end and a distal end, a central lumen extending through the outer tube, and a plurality of stiffening rods positioned around the central lumen. The plurality of stiffening rods may comprise a nonconductive material. The shaft may form part of an electrosurgical instrument. In another embodiment, a surgical instrument may comprise an end effector and a shaft having an outer tube having a proximal end and a distal end, a drive rod, and at least four stiffening rods positioned around the drive rod, each stiffening rod being positioned substantially immediately adjacent to the drive rod. The axial stiffness of the shaft increases incrementally during actuation of the end effector.

    Abstract: A force transmission mechanism for a teleoperated surgical instrument may include a gear, a push/pull drive element, and a connection element. The push/pull drive element may be configured to transmit force to actuate an end effector of the surgical instrument and to rotate with a shaft of the surgical instrument when the shaft is rotated by the force transmission mechanism. The connection element may operatively couple the gear and the push/pull drive element. The connection element may be configured to convert rotational movement of the gear to a substantially linear movement of the push/pull drive element. The connection element may be configured to rotate with the push/pull drive element and relative to the gear.

    Abstract translation: 用于远程手术的手术器械的力传递机构可以包括齿轮,推/拉驱动元件和连接元件。 推/拉驱动元件可以被配置成传递力以启动外科器械的端部执行器,并且当轴通过力传递机构旋转时,其与外科器械的轴一起旋转。 连接元件可以可操作地联接齿轮和推/拉驱动元件。 连接元件可以被配置为将齿轮的旋转运动转换成推/拉驱动元件的基本上线性的运动。 连接元件可以被构造成随着推/拉驱动元件相对于齿轮旋转。
