Abstract: A tool member is rotatably coupled to a distal end portion of a shaft and includes a drive pulley and a coupling spool. A mechanical structure is coupled to a proximal end portion of the shaft and includes first and second capstans. The first and second capstans each include a first portion and a second portion. A distal portion of the cable is wrapped at least one revolution about the coupling spool. A first proximal end of the cable is wrapped about the second portion of the first capstan such that a second portion crosses over a first portion of the first proximal end of the cable. The second proximal end of the cable is wrapped about the second portion of the second capstan such that a second portion of the second proximal end of the cable crosses over a first portion of the second proximal end of the cable.

Abstract: A medical device includes a chassis component having a bottom and an opening defined in the bottom, and a capstan including an upper portion, a lower portion, and a spool between the upper and lower portions. The upper portion of the capstan is supported within the opening of the chassis component. The spool comprises a cable wrap surface and a side wall opposing the bottom of the upper chassis. The side wall of the spool can optionally slope away from the bottom of the chassis component. The medical device can further include a cable guide and a cable. The cable extends from the cable guide to the cable wrap surface of the spool.

Abstract: A medical device includes a blade support, a blade supported by the blade support, and a pin. The blade support includes a bore with an inner portion oriented toward the blade and an outer portion oriented away from the blade. A discontinuity is located at a boundary between the inner and outer portions of the bore. The pin includes a longitudinal axis and a yaw plane is defined perpendicular to the longitudinal axis. A rotational yaw degree of freedom is defined about the longitudinal axis of the pin. The blade support is operable to rotate about the pin in the yaw degree of freedom, contact the pin at the discontinuity of the bore, and tilts away from the yaw plane at the discontinuity of the bore in response to a force applied in a lateral direction.
