Abstract

A positioning frame for supporting a patient to facilitate different surgical approaches to the spine includes a main support beam, first and second support structures, a torso-lift support, and a pelvic-tilt support. The main support beam has a first end, a second end, and a length extending between the first and second ends. The main support beam defines an axis of rotation relative to at least a first support structure and a second support structure, and the axis of rotation substantially corresponds to a cranial-caudal axis of the patient when the patient is supported on the positioning frame. The first and second support structures support the main support beam, and space the main support beam from the ground. The torso-lift support is attached to the main support beam, and is configured to pivot a chest support plate between at least a first position and a second position to move the torso of the patient between an unlifted position and a lifted position. The pelvic-tilt support is attached to the main support beam, and is configured to support the thighs and the lower legs of the patient. Portions of the pelvic-tilt support are pivotal with respect to one another to facilitate adjustment of the hips of the patient.

First claim

The positioning frame of claim 1 , wherein the torso support includes a chest support being configured to support the chest of the patient, the torso support being pivotally connected to the single main beam, the torso support being configured to pivot the chest support between at least a first position and a second position to move the torso of the patient between an unlifted position and a lifted position.

3. The positioning frame of claim 1 , wherein the pelvic support includes a thigh cradle and a lower leg cradle, the thigh cradle being configured to support thighs of the patient, and the lower leg cradle being configured to support lower legs of the patient, the thigh cradle and the lower leg cradle being pivotal with respect to one another to facilitate adjustment of hips of the patient.

4. The positioning frame of claim 1 , wherein the third portion of the single main beam includes a portion substantially parallel to the axis of rotation of the single main beam. leg cradle being configured to support lower legs of the patient, the thigh cradle and the lower leg cradle being pivotal with respect to one another to facilitate adjustment of hips of the patient.

5. The positioning frame of claim 1 , wherein, during rotation of the single main beam, the single main beam is configured to support the patient in a prone position in the first rotational position thereof, and is configured to support the patient in a lateral position in the second rotational position thereof.

6. The positioning frame of claim 1 , wherein the pelvic support is configured to manipulate the patient to open at least one space between adjacent vertebral bodies of the patient to facilitate placement of an interbody device in the at least one space.

7. The positioning frame of claim 1 , further comprising a head support and arm supports connected to the chest support, the head support and the arm supports being configured to support a head and arms of the patient during pivotal movement of the chest support.

8. The positioning frame of claim 1 , further comprising at least one actuator for articulating at least one of the single main beam, the torso support, and the pelvic support.

9. A positioning frame for supporting a patient, the positioning frame comprising:
a first support structure at a first positioning-frame end of the positioning frame, and a second support structure at an opposite second positioning-frame end of the positioning frame;
a single main beam having a first main-beam end, a second main-beam end, and a length extending between the first and second main-beam ends, the first support structure supporting the single main beam at the first main-beam end, the second support structure supporting the single main beam at the second main-beam end, the first support structure and the second support structure spacing the single main beam from the ground, the single main beam being rotatable about an axis of rotation between at least a first rotational position and a second rotational position,
