  • Publication number: 20240058080
    Abstract: An instrument driver comprises a base and a jaw assembly coupled to the base. The jaw assembly includes a first jaw having a gripping surface and a second jaw having a gripping surface. The instrument driver further comprises a driver assembly operably coupled to the jaw assembly to advance an elongated member relative to the base by translating the first and second jaws toward each other, thereby closing the jaw assembly and gripping the member between the respective gripping surfaces of the first and second jaws, translating the jaw assembly in a first axial direction when the jaw assembly is closed, translating the first and second jaws away from each other, thereby opening the jaw assembly and releasing the member from between the respective gripping surfaces of the first and second jaws, and translating the jaw assembly in a second axial direction when the jaw assembly is opened.

  • Patent number: 11660153
    Abstract: Various exemplary drive apparatuses and associated methods are disclosed for driving an elongated member, e.g., a catheter, sheath, or guidewire. An exemplary drive apparatus may include a first component and a moveable component, each configured to selectively grip the elongated member. In some examples, the first and moveable components may each include a gripping device. The moveable component may be configured to selectively move axially and rotationally with respect to a support surface to effect axial movement and rotation movement, respectively, of the elongated member with respect to the support surface within a range of motion of the moveable component. The moveable component may be configured to move the elongated member across a predetermined movement having a magnitude greater than the range of motion.

  • Publication number: 20230108161
    Abstract: An instrument driver comprises opposing rotatable gripping pads. Each of the gripping pads includes an outer circular rim and a center hub. The pads are configured for applying a gripping force to an elongated member. The instrument driver further comprises shafts affixed to the center hubs, and a driver assembly configured for rotating at least one of the shafts, thereby causing the pads to rotate in opposite directions to linearly translate the gripped member. Each of the pads further includes a framework for partially collapsing in response to the gripping force, such that portions of the rims flatten to contact each other. Each rim has a concave gripping surface in order to facilitate vertical centering of the member between the pads. Each of the pads further includes a pair of upper and lower sprockets for interlacing with each other to prevent the elongated member from slipping out between the pads.

  • Patent number: 8146874
    Abstract: An adapter plate assembly which provides a convenient interface between a mounting support assembly for suspending an instrument driver robotic instrument system above a operating table. The adapter plate securely mounts to the operating table, and may be adjustable so that it can be adjusted to fit various sizes and models of operating tables. The adapter plate assembly comprises a main plate which rests on the surface of the operating table. A first clamp assembly which removably attaches to the operating table is mounted on one or more horizontal adjustment rods which are slidably received in one of the main plate in order to provide adjustability to the width of the adapter plate assembly. On the opposing end of the main plate, a second clamp assembly is coupled main plate. In order to secure the support assembly of a robotic instrument system, an adapter rail is also coupled to the main plate.
