Abstract
Abstract An improved orthopedic attachment for receiving and supportably retaining the lower leg and foot of an orthopedic patient to permit traction to be applied to the leg during orthopedic operating procedures. The orthopedic device comprises a rigid support bracket for attachment to the operating end of a traction crank of an orthopedic operating table. Attached to the bracket is a tubular-shaped cuff member for receiving and surrounding the lower leg of a patient and having a fluid-activated inflatable bladder for grippingly engaging the lower leg to positively retain it therein. Also mounted on the bracket is an adjustable foot support plate which engages and positions the foot relative to the leg of the patient to positively position and retain the same so that traction force can be applied longitudinally of the leg to properly align and hold the bones of the leg in alignment during operating procedures.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
234 words
An orthopedic device to position and retain the lower portion of the leg and foot of the human body when the leg is placed in an extended position under traction during orthopedic operatory procedures, comprising: a rigid support bracket; tubular-shaped cuff means attached to the support bracket for surrounding and grippingly retaining the lower leg of the body adjacent the ankle, said cuff means including fluid-activated means for varying the size of the internal opening through the tubular-shaped cuff means to adjustably grip and retain the lower leg of the body; foot-positioning means mounted on said support bracket in spaced relation to said cuff means for positioning the foot when the lower leg is located in said cuff means, said foot-positioning means including a plantar plate extending generally transverse to the longitudinal axis of the tubular-shaped cuff means for receiving the sole of the foot, means attaching a heel-receiving portion of the plate to said support bracket for adjustable linear positioning of the heel-receiving portion toward and away from said cuff means along a line generally parallel to the longitudinal axis of the cuff means, means attaching a central portion of the plantar plate to the support bracket for adjustable positioning of the central portion linearly generally parallel to the longitudinal axis of the cuff means; and means on the bracket for supportably connecting the bracket to a force-applying member of an orthopedic table.
Claim 2
Dependent Claim
234 words
An orthopedic device to position and retain the lower portion of the leg and foot of the human body when the leg is placed in an extended position under traction during orthopedic operatory procedures, comprising: a rigid support bracket; tubular-shaped cuff means attached to the support bracket for surrounding and grippingly retaining the lower leg of the body adjacent the ankle, said cuff means including fluid-activated means for varying the size of the internal opening through the tubular-shaped cuff means to adjustably grip and retain the lower leg of the body; foot-positioning means mounted on said support bracket in spaced relation to said cuff means for positioning the foot when the lower leg is located in said cuff means, said foot-positioning means including a plantar plate extending generally transverse to the longitudinal axis of the tubular-shaped cuff means for receiving the sole of the foot, means attaching a heel-receiving portion of the plate to said support bracket for adjustable linear positioning of the heel-receiving portion toward and away from said cuff means along a line generally parallel to the longitudinal axis of the cuff means, means attaching a central portion of the plantar plate to the support bracket for adjustable positioning of the central portion linearly generally parallel to the longitudinal axis of the cuff means; and means on the bracket for supportably connecting the bracket to a force-applying member of an orthopedic table.
Claim 3
Dependent Claim
89 words
A device as defined in claim 1 where in said tubular-shaped cuff means comprises outer rigid circular means for receiving and surrounding the lower leg of the body, cushion means inside the rigid circular means for engaging the lower leg of the body; and wherein said fluid-activated means comprises an inflatable bladder positioned inside the rigid circular means to vary the size of the opening therethrough; and pump means conncected to the bladder to supply fluid to and release fluid from the bladder to expand and collapse the same.
Claim 4
Dependent Claim
29 words
A device as defined in claim 2 wherein said pump means comprises a hand-manipulated ball pump, and gauge means connected to the bladder for measuring the fluid pressure therein.
Claim 5
Dependent Claim
45 words
A device as defined in claim 2 wherein said rigid circular means comprise first and second semi-circular rigid plates pivotably hinged at one side to open and receive the leg, and fastening means for releasably securing the semi-circular plates in closed position surrounding the leg.
Claim 6
Dependent Claim
177 words
A device as defined in claim 1 wherein said support bracket comprises a rigid L-shaped member; said tubular-shaped cuff means is attached to one leg of the L-shaped member with its longitudinal axis extending generally parallel thereto; said means attaching the heel-receiving portion of the plantar plate to the support bracket includes an elongate slot in said one leg of the L-shaped member extending parallel to the longitudinal axis of the cuff means, and means pivotably mounting said heel-receiving portion of the plantar plate to said one leg of the L-shaped member for movement along the slot toward and away from the cuff means; and said means attaching the central portion of the plantar plate to the bracket includes an elongate member pivotably attached to the plantar plate and having an elongate slot therein, and means positioned in said elongate slot for adjustably securing the elongate member to the other leg of the L-shaped member to position the central portion of the foot plate means toward or away from the cuff means generally along thelongitudinal axis thereof.
Claim 7
Dependent Claim
56 words
A device as defined in claim 1 wherein said cuff means includes cushion means for grippigly retaining the lower leg of the human body, said cushion means being in surrounding engagement therewith just above the ankle of the leg and having a curved extension for engaging an arch portion of the foot of the human body.
Claim 8
Dependent Claim
28 words
A device as defined in claim 6 wherein said cushion means includes a recess for receiving the Achilles' tendon portion of the foot of the human body therein.
Claim 9
Dependent Claim
46 words
A device as defined in claim 1 including cushioning means on said plantar plate for engaging the sole of the foot of a body, and adjustable strap means for surrounding the toe end portion of the foot to secure the foot to the cushioned plantar plate.
Claim 10
Dependent Claim
58 words
A device as defined in claim 1 wherein said means for connecting the bracket to a force-applying member is located on said bracket generally on an extension of the longitudinal axis of said tubular-shaped cuff means whereby force applied by a force-applying member of an operating table will be directed along said longitudinal axis of the cuff means.
