Abstract
A fail-safe release mechanism for use with patient positioning support apparati having a base structure and a patient support structure, to prevent collapse of the patient support during disconnection of the patient support structure from the base structure.
Claims20
A method of supporting a patient support structure relative to a base structure, the method comprising
- providing the base structure having a first end support for supporting the patient support structure at a first end of the patient support structure, and a second end support at an opposite second end of the patient support structure, the first end support and the second end support spacing the patient support structure above an operating room floor when the patient support structure is supported thereby, and portions of each of the first end support and the second end support being moveable between a first lowered position and a second raised position;
- rotatably supporting a first rotatable support portion by the first end support, and rotatably supporting a second rotatable support portion by the second end support;
- tiltably attaching the first end of the patient support structure to the first end support via attachment of an attachment bracket of the patient support structure to the first rotatable support portion using a pin, and tiltably attaching the second end of the patient support structure to the second end support via attachment to the second rotatable support portion;
- and
- moving at least one engagement member moveably attached to the first rotatable support structure from a first position to a second position to prevent removal of the pin and disattachment of the attachment bracket from the first rotatable support portion;
- one of raising and lowering the first end of the patient support structure via movement of the portion of the first end support, and one of raising and lowering the second end of the patient support structure via movement of the portion of the second end support;
- rotating the patient support structure by rotating the first rotatable support portion and the second rotatable support portion;
- and
- tilting the first end of the patient support structure one of upwardly and downwardly via tiltable adjustment of the first end of the patient support structure relative to the first rotatable support portion, and tiltable adjustment of the second end of the patient support structure relative to the second rotatable support portion to angle the patient support structure from a neutral position parallel to the operating room floor to one of a Trendelenburg position and a reverse Trendelenburg position;
- wherein the patient support structure can be positioned and repositioned during surgery to provide desired heights, rotational angles, and tilt angles for the patient support structure.

- and
- tilting the first end of the patient support structure one of upwardly and downwardly via tiltable adjustment of the first end of the patient support structure relative to the first rotatable support portion, and tiltable adjustment of the second end of the patient support structure relative to the second rotatable support portion to angle the patient support structure from a neutral position parallel to the operating room floor to one of a Trendelenburg position and a reverse Trendelenburg position.

- tilting the first end of the patient support structure one of upwardly and downwardly via tiltable adjustment of the first end of the patient support structure relative to the first rotatable support portion, and tiltable adjustment of the second end of the patient support structure relative to the second rotatable support portion to angle the patient support structure from a neutral position parallel to the operating room floor to one of a Trendelenburg position and a reverse Trendelenburg position;
- articulating a first portion and a second portion of the patient support structure hingedly attached to one another adjacent a midpoint of the patient support structure;
- and
- one of raising, via relative articulation of the first portion and the second portion, the midpoint of the patient support structure above the first end and the second end of the patient support structure, and lowering, via relative articulation of the first portion and the second portion, the midpoint of the patient support structure below the first end and the second end of the patient support structure.
