Abstract
An orthopedic walking boot includes a housing configured to encompass at least a user's foot, a mechanically adjustable ramp insert including a ramp surface and disposed in the housing, and an adjusting mechanism configured to adjust an elevation angle of the ramp surface. The mechanically adjustable ramp insert includes a base, a threaded shaft secured to the adjusting mechanism at a first end and configured to rotate with the adjusting mechanism, a first slider nut including internal threads, a bracket in physical contact with the ramp surface, a first support coupled to the first slider nut at a first end and to the bracket at a second end, and a second support coupled to the base at a first end and to the bracket at a second end.
Claims19
An orthopedic walking boot, comprising:
- a housing configured to encompass at least a user's foot;
- a mechanically adjustable ramp insert disposed in the housing and comprising:
- a ramp surface,
- a base,
- a threaded shaft secured to an adjusting mechanism at a first end and configured to rotate with the adjusting mechanism,
- a first slider nut comprising internal threads, the first slider nut configured to move along the threaded shaft as the threaded shaft is rotated,
- a bracket in physical contact with the ramp surface,
- a first support coupled to the first slider nut at a first end and to the bracket at a second end, and
- a second support coupled to the base at a first end and to the bracket at a second end, wherein the first end of the first support is configured to move toward the first end of the second support, thereby causing mechanically adjustable ramp insert to elevate the ramp surface;
- and
- the adjusting mechanism configured to adjust an elevation angle of the ramp surface.
A method for adjusting an orthopedic walking boot, comprising:
- adjusting an adjusting mechanism disposed on a housing of the orthopedic walking boot thereby achieving a desired elevation angle of a ramp surface of a mechanically adjustable ramp insert of the orthopedic walking boot;
- and
- inserting a user's foot into the housing and disposing the user's foot on the ramp surface such that the user's foot is supported in a position of plantarflexion determined at least in part by the desired elevation angle of the ramp surface, wherein, within the mechanically adjustable ramp insert, adjusting the adjusting mechanism causes:
- a threaded shaft secured to the adjusting mechanism at a first end to rotate with the adjusting mechanism;
- a first slider nut comprising internal threads in physical contact with the threaded shaft to move along the threaded shaft as the threaded shaft is rotated;
- and
- a first end of a first support coupled to the first slider nut to move toward a first end of a second support coupled to the base, wherein a second end of the first support and a second end of the second support are both coupled to a bracket in physical contact with the ramp surface thereby causing mechanically adjustable ramp insert to elevate the ramp surface.
