Patient positioning system
A patient support system may include a pelvic bolster assembly and a thoracic bolster assembly. Each of the assemblies may be attached to a conventional surgical table frame by the surgical table frame's longitudinal rails. A plurality of adjustment mechanisms and components are provided to allow for easy and safe manipulation of a patient before and during surgery.
1. A patient support system, comprising:
a pelvic bolster assembly comprising:
a base, the base having a lower portion and an upper portion, the lower portion and upper portion connected via a drive mechanism such that the upper portion is rotatable relative to the lower portion in a coronal plane, the lower portion of the base having a first channel on a first lateral side and a second channel on an opposing lateral side, the first and second channels slidably mountable on opposing rails of a surgical bed frame;
a first lateral bolster attached to a first lateral side of the upper portion of the base and a second lateral bolster attached to an opposing lateral side of the upper portion of the base, the first lateral bolster and second lateral bolster adjustable relative to the upper portion in a transverse plane; and
a thoracic bolster assembly comprising:
a base, the base having a lower portion and an upper portion, the lower portion and upper portion connected via a drive mechanism such that the upper portion is rotatable relative to the lower portion in a coronal plane, the lower portion of the base having a first channel on a first lateral side and a second channel on an opposing lateral side, the first and second channels slidably mountable with opposing rails of a surgical bed frame; and
a first lateral bolster attached to a first lateral side of the upper portion of the base and a second lateral bolster attached to an opposing lateral side of the upper portion of the base, the first lateral bolster and second lateral bolster adjustable relative to the upper portion in a sagittal plane and in a transverse plane.
2. The patient support system of claim 1 , wherein the pelvic bolster assembly further comprises at least one pelvic support pad attached to the upper portion of the base of the pelvic bolster assembly, and
wherein the thoracic bolster assembly further comprises a thoracic support pad attached to the upper portion of the base of the thoracic bolster assembly.
3. The patient support system of claim 2 , wherein the at least one pelvic support pad comprises a first pelvic support pad and a second pelvic support pad.
4. The patient support system of claim 3 , wherein the upper portion of the base of the pelvic bolster assembly further comprises a first gusset and a second gusset attached thereto, and wherein the first pelvic support pad is connected to the first gusset and the second pelvic support pad is connected to the second gusset.
5. The patient support system of claim 1 , wherein the first lateral bolster of the pelvic bolster assembly is removably attached to the first lateral side of the upper portion of the base, and wherein the second lateral bolster is removably attached to the opposing lateral side of the upper portion of the base.
6. The patient support system of claim 1 , wherein the first and second channels of the pelvic bolster assembly are C-channels and the first and second channels of the thoracic bolster assembly are C-channels.
7. The patient support system of claim 1 , wherein the drive mechanism comprises a worm gear.
8. The patient support system of claim 1 , wherein the drive mechanism is motorized.
9. A patient support system, comprising:
a pelvic bolster assembly and a thoracic bolster assembly, each comprising:
a base, the base having a lower portion and an upper portion, the lower portion and upper portion connected via a drive mechanism such that the upper portion is rotatable relative to the lower portion in a coronal plane of the patient, the lower portion of the base having a first channel on a first lateral side and a second channel on an opposing lateral side, the first and second channels slidably mountable with opposing rails of a surgical bed frame;
a first lateral bolster removably attached to a first lateral side of the upper portion of the base and a second lateral bolster removably attached to an opposing lateral side of the upper portion of the base, the first lateral bolster and second lateral bolster adjustable in a sagittal plane and in a transverse plane;
wherein the drive mechanism is a worm drive comprising a worm shaft attached to the lower portion of the base, and a worm gear attached to the upper portion of the base, the worm gear coupled to the worm shaft; and
wherein the pelvic bolster assembly further comprises a pelvic support pad attached to the upper portion of the base of the pelvic bolster assembly, wherein the thoracic bolster assembly further comprises a thoracic support pad attached to the upper portion of the base of the thoracic bolster assembly, and wherein the first lateral bolster and second lateral bolster further comprise a lateral support pad attached to each lateral bolster.
10. The patient support system of claim 9 , wherein the worm drive is motorized.
11. The patient support system of claim 9 , further comprising a coronal adjustment handle coupled to the worm shaft.
12. The patient support system of claim 9 , wherein one or more of the pelvic support pad, thoracic support pad, and lateral support pads are removable.
