PATIENT POSITIONING SUPPORT STRUCTURE WITH TRUNK TRANSLATOR

摘要

A patient support structure includes a pair of independently height-adjustable supports, each connected to a patient support. The supports may be independently raised, lowered, rolled or tilted about a longitudinal axis, laterally shifted and angled upwardly or downwardly. Position sensors are provided to sense all of the foregoing movements. The sensors communicate data to a computer for coordinated adjustment and maintenance of the inboard ends of the patient supports in an approximated position during such movements. A longitudinal translator provides for compensation in the length of the structure when the supports are angled upwardly or downwardly. A patient trunk translator provides coordinated translational movement of the patient's upper body along the respective patient support in a caudad or cephalad direction as the patient supports are angled upwardly or downwardly for maintaining proper spinal biomechanics and avoiding undue spinal traction or compression.

主权项

1. An apparatus for supporting a patient during a medical procedure, the apparatus comprising:
a. first and second opposed end support assemblies; b. first and second patient supports, each of the first and second patient supports including an outboard end and an inboard end, each of the outboard ends connected to a respective one of the first and second end support assemblies by at least one angulation assembly, each of the at least one angulation assemblies configured to position one of the patient supports in a plurality of angular orientations; c. the patient support inboard ends forming an articulation and being moved by one or both of the at least one angulation assemblies; d. a trunk translator slidingly engaged with one of the first and second patient supports and configured to support an upper body of the patient, the trunk translator configured for translational movement relative to the one of the first and second patient supports; and e. a trunk actuator coupled with the trunk translator and operable to move the trunk translator with respect to the one of the first and second patient supports, wherein movement of the trunk translator is controlled via a controller and is independent from movement of the first and second patient supports.
