摘要:
An adjustable knee brace for fitting a variety of leg sizes and adjustable to limit flexion or extension motion of a knee. The knee brace includes an adjustable length provided by a strut that telescopes within a receiver. A latch assembly mounted on the receiver selectively applies a frictional force to lock the strut member and the receiver against relative telescoping movement. An adjustable range of motion hinge is operatively associated with the telescoping strut. The hinge includes a hinge plate connected to the strut member and having a semi-circular peripheral edge defining a plurality of uniformly spaced apart keys. A range of motion stop is movably positionable relative to the semi-circular peripheral edge and includes a movable latch having teeth. The latch is movable away from the keys to an unlocked position in which the stop is movable relative to the keys, and the movable latch is movable toward and into engagement with the keys to a locked position in which the range of motion stop is not movable relative to the keys. The range of motion stop defines a limit of rotational movement of the range of motion hinge to limit extension or flexion motion of the knee.

An orthopedic device includes an elongate and rigid or semirigid strut assembly, an arcuate cuff pivotally secured to the strut assembly, and a strap securing to the cuff and forming an adjustable circumferential configuration therewith. A tensioning device may be mounted on the cuff and coupled to the strap in order to incrementally adjust the tensioning device among a plurality of preselected levels such that a first end of the strap secures to the tensioning device and a second end of the strap couples to the cuff. A soft-good assembly connects to the strut assembly and has a flexible stay embedded within with a plurality of layers. The soft-good assembly is adapted to form an adjustable circumferential loop with the stay only located within a segment short of the circumference of the loop.

There is shown an artificial joint (1), which joint has a first part (11) adapted to be attached at a wearer's first body part or substitute body part, and a second part (12) adapted to be attached to a second body part or substitute body part, wherein the first part (11) and the second part (12) can be rotated relatively each other and are connected to each other by means of at least four shafts (21, 22, 23, 24) and corresponding links (13, 14, 15). The joint (1) is characterised in that it is freely moveable when the joint is unloaded by the wearer, and in loaded position the same joint is geometrically locked.

An ankle foot orthosis includes a leg member, a foot member, and a drive member. The drive assembly includes a link member which may be hingedly secured to the foot member at a hinge location adjacent to the posterior end of the foot member. The drive assembly may be operable to selectively impart pivotal movement between the foot member and the link member about a first pivot axis, and pivotal movement between the foot member and the leg member about a second pivot axis at the hinge location. The leg member and the foot member strut may be selectively movable in a medial-lateral direction relative to a base of the foot member and the drive assembly. The inferior-superior location of the second pivot axis may be selectively adjustable for substantially aligning the second pivot axis with an axis of rotation of an ankle joint of the wearer.

An orthopedic device has first and second elongate struts each having a strap coupling member, and a flexible strap securing to the first and second struts by the strap coupling members. A semi-rigid and resiliently bendable expander is connected to and spans a predetermined length between the struts. The expander provides two main configurations for the orthopedic device including maintaining the first and second struts in a generally flat configuration relative to one another and a curved configuration upon application of a load on the first and second struts. The expander reverts to a flat configuration upon removal of a load or from the first and second struts.

An orthotic device includes an upper arm section for receiving an upper portion of an arm of a subject, a forearm section for receiving a forearm section of the arm, and at least one elbow joint rotatably coupling the upper arm section and the forearm section. In the orthotic device, the forearm section includes a release control operatively coupled to the at least one elbow joint, where the release control is configured to transition the at least one elbow joint from a restricted motion state to a free motion state when the release control is activated.

An articulated joint for orthopedic orthoses or braces, where the brace comprises rods for the tibia (51) and rods for the femur (52) and an articulated hinge (53) provided with four pivots designed to ensure the necessary mobility obtained by the presence of multiple centres of rotation, and where the articulated hinge (53) comprises two plates (55, 56) reciprocally connected by means of four quadrilaterally positioned hinging means such as rivets (57) or similar, in order to enclose the ends of the rods (51, 52) which face each other, wherein between the ends of the two rods (51, 52) there are spacers or stops (63), and where the outer plate (55) of the articulated hinge (53) presents openings (61, 62) in which are inserted pairs of stops (63) which limit the ROM of the joint.

The invention relates to a join mechanism of a knee orthosis or knee prosthesis, having a first part (14), a second part (15), which is pivotable relative to the latter, and attachment means (2) for securing the joint mechanism (1) to a user of the knee orthosis or knee prosthesis, and having a locking mechanism (4, 40) with which a pivoting of the two parts (14, 15) relative to each other in a flexion direction is prevented by a form-fit element (4) which is arranged movably on the second part (15) and which, in the locking state, engages with a form fit in a recess (40) assigned to the first part (14), wherein the form-fit element (4) is mounted rotatably on the second part (15) and has a contour which, in the locked position, protrudes into the recess (40) and, in the released position, allows the first part (14) to pivot past the bearing of the form-fit element (4).

A hinge for an orthopedic brace includes: a pivot shaft; a lower leg plate pivoted to the pivot shaft; an upper leg plate; a catch plate having a toothed peripheral edge; and two position adjusting units, each of which includes a rotatable limiting seat, a limiting pin, and a slider body. The rotatable limiting seat defines a housing chamber therein, and is formed with a wall slot. The slider body is slidably disposed in the housing chamber. The limiting pin extends from the slider body through the wall slot for engaging and disengaging the toothed peripheral edge. The catch plate is formed with a guiding groove. The rotatable limiting seat has a tongue protruding into the guiding groove.

An angle-adjustable rehabilitation device includes first and second racks between two lateral covers, a locking unit of the second rack is capable of switching the first rack between an adjustable position and a nonadjustable position. When in the adjustable position, the rotatable angle of the first rack can be freely adjusted. The control members of the two angle-adjustment positioning members protrude out of the two lateral covers, therefore, angle adjustment can be easily done without removing any components. Furthermore, the arc-shaped angle scale on the two lateral covers makes the angle adjustment more readable and controllable, and the first rack can be moved back into the non-adjustable position automatically after angle adjustment is done.
