  • Patent number: 6058534
    Abstract: A surgical boot assembly for an operating room table includes a surgical boot, an adjustable support arm securable to the table, and an adjustable clamping assembly attaching the surgical boot to the adjustable support arm. The adjustable support arm includes an attachment, a support rod having an end pivotally attached to the attachment such that the support rod is pivotable about the end relative to the attachment, and a locking cylinder having a first end pivotally attached to the attachment and a second end pivotally attached to the support rod. The locking cylinder is infinitely adjustable over a range and can provide an assisting lift force. The locking cylinder preferably includes a cylinder, a piston within the cylinder and having an integral valve, and a separating piston within the cylinder. The piston and the separating piston divide the cylinder into first, second, and third portions.

  • Patent number: 5961085
    Abstract: An adjustable support arm for an operating room table includes an attachment, a support rod having an end pivotally attached to the attachment and pivotable about a lithotomy axis, and a lithotomy locking cylinder operably attached to the support rod. The lithotomy locking cylinder can be unlocked to raise or lower the support rod about the lithotomy axis and locked to retain the support rod in the desired lithotomy position. The lithotomy locking cylinder is infinitely adjustable over a range and can provide an assisting lift force. The support rod can also be pivotable about an abduction axis with an abduction locking cylinder operably attached to the support rod. The abduction locking cylinder can be unlocked to laterally pivot the support rod about the abduction axis and locked to retain the support rod in the desired abduction position. The abduction locking cylinder is infinitely adjustable over a range and can provide a bias force to a minimum abduction position.

  • Patent number: 5940912
    Abstract: An armboard assembly that is X-ray translucent and includes a board pivotably connected to a latching assembly. A locking assembly, which is disposable inside the board, is connected to the latching assembly and the board. The locking assembly is operable to selectively secure the board from movement relative to the latching assembly. The board defines a handle opening within which is disposed a grip for controlling the locking assembly.

  • Patent number: 5802641
    Abstract: A leg holder system for simultaneously positioning in the abduction and lithotomy dimensions including a support device for supporting a leg cradle; a clamping device for mounting the proximate end of the support device to a mounting device having a first axis and selectively clamping and releasing motion of the support device about the first axis and about a second axis transverse to the first axis. An actuator device for actuating the clamp to selectively clamp and release simultaneously the support device and the mounting device; and an operator device remote from the clamping device and actuator device for operating the actuator device to enable the support device to move simultaneously about the first and second axis in both the lithotomy and abduction dimensions.

  • Patent number: 4898491
    Abstract: A pivot assembly including a rotating member, a mounting member for supporting the rotating member, and a pivotal interconnection for the members. The interconnection enables rotation about a pivot axis and inhibits translation of the rotating member relative to the mounting member along the pivot axis. There are also structure enabling tilting of the rotating member about a tilt axis transverse to the pivot axis, and gripping elements for inhibiting relative rotation about the pivot axis. The gripping elements increase grip between the adjacent sections when the rotating member is tilted about the tilt axis in a first direction, and decrease grip when the rotating member is tilted about the tilt axis in a second and opposite direction to enable rotation of the rotating member.

  • Patent number: 4736959
    Abstract: A convertible carriage including a superstructure with a seat for carrying a person to be transported, and a number of wheels. The wheels are rollably supported by wheel support structure which is movably interconnected with the superstructure. The superstructure is rollably transportable when the wheel support structure and wheels are in an extended position. The carriage further includes a device for relocating the wheels concurrently between the extended position and a retracted position in the superstructure.

  • Patent number: 4698837
    Abstract: An armboard mounting assembly including an armboard having a proximate and a distal end, an armboard mount, and a joint for pivotably interconnecting the armboard and the armboard mount for enabling rotation of the armboard about a pivot axis. The rotatable armboard and armboard mount have at least one pair of adjacent sections, and the assembly further includes friction members (or alternate grippers) for providing gripping between said adjacent sections, said friction members being responsive to a downward force on the armboard between the pivot axis and the distal end for increasing gripping between the adjacent sections and inhibiting relative rotation about the pivot axis. Depending on the materials used, the armboard mounting assembly is radiologically translucent, NMR (nuclear magnetic resonance)-compatible, or both.
