Abstract
An orthopedic system wherein a patient's brain is operably coupled to an actuation assembly for voluntarily moving a brace/limb of the patient between a number of desirable positions. An orthopedic brace, or one of more components thereof, which can be utilized with the orthopedic system.
Claims27
An orthopedic device comprising
- an orthopedic brace configured to be worn by a user, the orthopedic brace including an upper portion, a lower portion, and a multi-axial mechanical joint extending between and interconnecting the upper portion and the lower portion of the brace, the upper portion of the brace configured to be selectively attached to an upper portion of a limb of the user and the lower portion configured to be selectively attached to a lower portion of the limb of the user such that the multi-axial joint is proximate to a joint of the user between the upper and lower portions, and the multi-axial joint configured to rotate between a plurality of predetermined arrangements,
- an assembly coupled to the multi-axial joint of the brace and configured to move the upper and lower portions of the brace between the plurality of predetermined arrangements, the assembly including a first actuator coupled to the multi-axial joint and configured to move the upper and lower portions of the brace in a flexion direction and an extension direction between the plurality of predetermined arrangements, and
- a control unit coupled to the assembly and configured to selectively actuate the assembly to move the orthopedic brace to a predetermined arrangement included in the plurality of predetermined arrangements in response to a signal associated with the predetermined arrangement,
- wherein the multi-axial joint is a ball and socket joint, the ball and socket joint including a rotatable ball portion including a ball arm extending along a center ball axis and coupled to the lower portion of the orthopedic brace and a ball coupled to one end of the ball arm with a center located on the center axis, and a socket portion including a socket arm that extends along a center socket axis and coupled to the upper portion of the orthopedic brace and a socket housing coupled to one end of the socket arm that forms a ball socket, the socket housing including at least two prongs, wherein the ball is located in the at least two prongs of the ball socket to couple the rotatable ball portion to the socket portion.

An orthopedic brace configured to be worn by a user, the orthopedic brace comprising:
- an upper portion configured to be selectively attached to an upper portion of a limb of the user, a lower portion configured to be selectively attached to a lower portion of the limb of the user, and a multi-axial joint extending between and interconnecting the upper portion and the lower portion of the brace and proximate to a joint of the user between the upper and lower portions, the multi-axial joint configured to rotate between a flexed arrangement, an extended arrangement, a supinated arrangement, and a pronated arrangement,
- wherein the multi-axial joint is a ball and socket joint, the ball and socket joint including a rotatable ball portion including a ball arm extending along a center ball axis and coupled to the lower portion of the orthopedic brace and a ball coupled to one end of the ball arm with a center located on the center axis, and a socket portion including a socket arm that extends along a center socket axis and coupled to the upper portion of the orthopedic brace and a socket housing including at least two prongs coupled to one end of the socket arm that forms a ball socket, wherein the ball is located in the ball socket to couple the rotatable ball portion to the socket portion.
An orthopedic system, comprising:
- a brace configured to be placed around an inoperable limb of a patient, the limb having an anatomical joint and at least one inoperable muscle, wherein the brace includes a first component and a second component attached by a mechanical joint, the mechanical joint including a ball and socket joint, the ball and socket joint including a rotatable ball portion including a ball arm, the rotatable ball portion coupled to the first component of the orthopedic brace and a ball coupled to one end of the ball arm, and a socket portion including a socket arm coupled to the second component of the orthopedic brace and a socket housing including at least two prongs coupled to one end of the socket arm that forms a ball socket, wherein the ball is located in the ball socket to couple the rotatable ball portion to the socket portion,
- an actuation assembly operably coupled to the first and second components of the brace so that activation of the actuation assembly causes movement of at least one of the components around the joint,
- a control unit interfaced with the actuation assembly so the control unit can send an instruction signal to the actuation assembly, and
- a sensor configured to be in communication with (i) the control unit and (ii) at least one of the patient's operable muscles, wherein the sensor has a predetermined threshold of detecting contraction of the at least one operable muscle.

A method of operating an orthopedic system having
- (i) a brace that includes a first component and a second component attached by a joint, the joint including a ball and socket joint, the ball and socket joint including a rotatable ball portion including a ball arm, the rotatable ball portion coupled to the first component of the orthopedic brace and a ball coupled to one end of the ball arm, and a socket portion including a socket arm coupled to the second component of the orthopedic brace and a socket housing including at least two prongs coupled to one end of the socket arm that forms a ball socket, wherein the ball is located in the ball socket to couple the rotatable ball portion to the socket portion,
- (ii) an actuation assembly operably coupled to the first and second components so that activation of the actuation assembly causes movement of at least one of the components around the joint,
- (iii) a control unit interfaced with the actuation assembly so the control unit can send a signal to the actuation assembly,
- (iv) a sensor operatively coupled to the control unit, the sensor capable of sensing a signal from a voluntary muscle contraction and sending a signal to the control unit to activate the actuation assembly, the method comprises steps of:
- positioning the brace in contact with a limb of a patient wherein the limb has
- {i) a first bone component and a second bone component attached by a joint and
- {ii) at least one muscle operably coupled to the first bone component and/or second bone component but is incapable of generating a signal;
- and positioning the sensor on the skin of the patient so the sensor can communicate with a muscle capable of generating a signal, wherein the muscle is not operatively coupled to the first or second bone component.
