PROSTHESIS CARRING BARREL SUCTION-ATTACHING JOINT WITH LOCKING FUNCTION
20170333225 · 2017-11-23 ·

A prosthesis carrying barrel suction-attaching joint with locking function, particularly a joint specifically for suction-attachment to a carrying barrel, includes a positioning mechanism, which forms, in a center thereof, a positioning pin hole for receiving a positioning pin to dispose therein. The positioning mechanism is provided, in a lateral direction, with a penetration passage and a vacuum release passage in communication with the positioning pin hole. The penetration passage has two ends on opposite sides of the positioning pin hole. One of the ends is provided with a regulation assembly and another one provided with a locking assembly. The locking assembly includes a constraint block for retaining the positioning pin so that a chamber for vacuum regulation is formed in the site where the regulation assembly is arranged. Pressing down the locking assembly allows external air to flow through the vacuum release passage into the chamber to release the vacuum.

Method and apparatus for a prosthetic stand
09791094 · 2017-10-17 ·

Various embodiments of a prosthetics stand having a base with a post that extends upwardly from the base and a holder component coupled to the post and having a pair of holders configured to secure and store one or more lower-extremity prosthetics are disclosed. The pair of holders each defines a circular portion that forms an opening slot configured to allow a lower-extremity prosthetic pass through and be retained within the confines of each respective holder. The prosthetic stand includes a plurality of wheels that allow the prosthetic stand to be mobile and a securing means operable to allow the prosthetics stand to be attached to a structural element, such as a bed or bathtub, to prevent inadvertent movement of the holder component. In some embodiments, the base may have an angled portion that allows the lower-extremity prosthetic to be attached and reattached to an individual in a more natural and convenient manner.

Hands-free apparatus to apply a liner to an amputated appendage
11253378 · 2022-02-22 ·

A liner to an appendage of a user includes a base member, a bracket adjustably mounted to the base member to a desired height position, and a plurality of arms pivotably mounted to the bracket. Each arm can include a rotating member, such as a roller ball, coupled to a top end of the arm. The plurality of arms can extend from the bracket in a generally upright position and can support the liner thereon in an inside out position so that the application of downward pressure by the appendage of the user within the plurality of arms permits the arms to pivot outward, thereby allowing the plurality of arms and roller balls to slide the liner around the appendage of the user.

Alignment adapter for prosthetic sport feet
09737420 · 2017-08-22 · ·

An alignment adapter for prosthetic sport feet, such as running feet, includes a male pyramid plate having a male pyramid, a female connector plate having a female connector, and a back plate. For use during alignment of a prosthetic running foot, the male pyramid plate is coupled to the back of a user's socket and the female connector plate and back plate are clamped about the foot. The male pyramid and female connector are coupled and adjusted relative to one another to achieve a desired alignment. The socket and foot are locked in an alignment fixture to maintain the alignment and the male pyramid, female connector, and back plates are removed. A laminated plate is coupled to the socket to maintain alignment during normal use.

Prosthetic attachment device for osseointegrated implants

Technology is described for easy and safe attachment of a prosthetic limb to a percutaneous post that has been osseointegrated into the remnant limb of an individual with limb loss. A quick-disconnect device for a prosthetic limb can comprise a percutaneous post support assembly comprising a post locking assembly attached to a percutaneous post. A roller support can be coupled to the percutaneous post support assembly and can support torsional breakaway rollers. A release housing assembly can be coupled to the percutaneous post support assembly, and can comprise a limb support housing supporting a limb attachment structure to support a prosthetic limb. The release housing assembly comprises a torsional breakaway spring. The plurality of torsional breakaway rollers are each biased to the torsional breakaway spring to generate a spring force to restrict or limit rotation of the percutaneous post support assembly. Other breakaway springs and rollers are provided for bending release and axial release.

Suspended sleeve assembly comprising a compression sleeve and a suspension stand
11331206 · 2022-05-17 · ·

A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.
