Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
107 words
Apparatus for positioning the body of a patient during heart surgery and the like comprising: a pair of spaced leg supports each having a leg support surface which includes: a resilient deformable thigh support surface having a sloping contour for properly positioning the thigh portion of said leg, a resilient deformable calf support surface having a sloping contour for properly positioning the calf portion of said leg, said thigh and calf support surfaces positioning said leg in an externally rotated position affording access thereto, and a knee support portion having pressure relief means for relieving pressure on said leg in the peroneal nerve area avoiding damage thereto.
Claim 2
Dependent Claim
107 words
Apparatus for positioning the body of a patient during heart surgery and the like comprising: a pair of spaced leg supports each having a leg support surface which includes: a resilient deformable thigh support surface having a sloping contour for properly positioning the thigh portion of said leg, a resilient deformable calf support surface having a sloping contour for properly positioning the calf portion of said leg, said thigh and calf support surfaces positioning said leg in an externally rotated position affording access thereto, and a knee support portion having pressure relief means for relieving pressure on said leg in the peroneal nerve area avoiding damage thereto.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein each said leg support surfaces includes a depression intermediate the thigh and calf support surfaces affording substantially zero pressure on the peroneal nerve area of the leg.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 wherein said depression is defined by a hollow cut-out portion formed in said leg supporting surface intermediate said thigh and calf supporting surfaces.
Claim 5
Dependent Claim
36 words
The apparatus of claim 1 including pressure distribution means serving to break the integrity of said thigh and calf support surfaces accommodating differences in thigh and calf shapes and weights and evenly distributing the pressure thereon.
Claim 6
Dependent Claim
24 words
The apparatus of claim 4 wherein said pressure distribution means includes elongated slits extending generally longitudinally in each said thigh and calf support surface.
Claim 7
Dependent Claim
35 words
The apparatus of claim 1 including a foot support means for supporting foot and ankle portions of said leg having an adjustable support for supporting said foot and ankle in a variety of elevated positions.
Claim 8
Dependent Claim
42 words
The apparatus of claim 1 wherein said foot support means includes a block member integral with said calf support surface, a recess opening formed in said block member, and a removable friction member received in said recess opening and vertically adjustable therein.
Claim 9
Dependent Claim
23 words
The apparatus of claim 7 wherein said friction member includes a curled strip of resilient deformable material frictionally held in said recess opening.
Claim 10
Dependent Claim
29 words
The apparatus of claim 1 including cut-out means formed in a bottom surface of each said leg support for accommodating the placement and routing of tubing and the like.
Claim 11
Dependent Claim
20 words
The apparatus of claim 1 wherein said leg supports are integrally joined by a web limiting the lateral separation therebetween.
Claim 12
Dependent Claim
19 words
The apparatus of claim 1 wherein said thigh and calf supporting surfaces have a longitudinal and lateral sloping contour.
Claim 13
Dependent Claim
137 words
Apparatus for positioning the body of a patient during surgery comprising: a pair of spaced leg supports each having a leg support surface for supporting a leg of said patient which includes; a resilient deformable thigh support surface having a longitudinally and laterally sloping contour for properly positioning the thigh portion of said leg, said laterally sloping contour of said thigh support surface sloping from a high inside edge downwardly to a lower outside edge so as to cause the thigh portion of said leg to be externally rotated when supported thereon, a resilient deformable calf support surface having a longitudinally and laterally sloping contour for properly positioning the calf portion of said leg, and said thigh and calf support surfaces positioning said leg in a proper externally rotated position affording stability and access thereto for surgery.
Claim 14
Dependent Claim
137 words
Apparatus for positioning the body of a patient during surgery comprising: a pair of spaced leg supports each having a leg support surface for supporting a leg of said patient which includes; a resilient deformable thigh support surface having a longitudinally and laterally sloping contour for properly positioning the thigh portion of said leg, said laterally sloping contour of said thigh support surface sloping from a high inside edge downwardly to a lower outside edge so as to cause the thigh portion of said leg to be externally rotated when supported thereon, a resilient deformable calf support surface having a longitudinally and laterally sloping contour for properly positioning the calf portion of said leg, and said thigh and calf support surfaces positioning said leg in a proper externally rotated position affording stability and access thereto for surgery.
Claim 15
Dependent Claim
26 words
The apparatus of claim 12 including depression means intermediate said thigh and calf support surfaces limiting the pressure on the peroneal nerve area of said leg.
Claim 16
Dependent Claim
30 words
The apparatus of claim 12 including foot support means having a vertically adjustable support means for supporting foot and ankle portions of the leg at a desired elevation and pressure.
Claim 17
Dependent Claim
29 words
The apparatus of claim 12 including adjustable foot support means affording support of the foot portion of said leg with substantially zero pressure on the ankle bone portion thereof.
Claim 18
Dependent Claim
36 words
The apparatus of claim 12 including pressure distribution means serving to break the integrity of said thigh and calf support surfaces accommodating differences in thigh and calf shapes and weights and evenly distributing the pressure thereon.
Claim 19
Dependent Claim
72 words
