Patent number: 11911299Abstract: A prosthetic attachment system and corresponding lock assembly for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket. The lock assembly includes a base arranged to be supported by the distal end of the prosthetic socket, and defining a bore. An attachment pin is arranged to be carried by the prosthetic liner and insertable through the bore. A lock mechanism is arranged to be carried by the base and is rotatable about a rotation axis. The lock mechanism includes a control knob extending outwardly from a side of the base. The attachment pin is arranged to interact with the lock mechanism cause the control knob to spin at least one projection of the control knob about the rotation axis.Type: GrantFiled: October 22, 2021Date of Patent: February 27, 2024Assignee: OSSUR ICELAND EHFInventors: Sigurdur Hannesson, Andrew Bache, Dadi Granz

Publication number: 20230058917Abstract: A prosthetic attachment system and corresponding lock assembly are provided for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket, by combining vacuum suspension and mechanical suspension. An attachment pin extends from a distal end of the prosthetic liner. A connector assembly secures to a distal end of the prosthetic socket and is adapted for receiving and locking to the attachment pin. A lanyard assembly has a first end secured to the connector assembly and a second end extending outwardly from the distal end of the prosthetic socket and adapted to secure to an exterior surface of the prosthetic socket by an external securing system.Type: ApplicationFiled: August 18, 2022Publication date: February 23, 2023Inventors: Hafsteinn JONASSON, Sigurdur HANNESSON, Oskar Thor LARUSSON, Margret Sol RAGNARSDOTTIR, Halldor ALBERTSSON

Publication number: 20220142794Abstract: A ventilated prosthetic socket includes a rigid, structural and load-bearing socket body forming an inner volume adapted to receive a residual limb, and a wall thickness extending from an inner wall surface bordering the inner volume to an outer wall surface. The socket body defines an opening extending through the wall thickness. At least one vent element communicates the inner wall surface to the outer wall surface and extending therebetween in the opening along the socket body to thereby permit a transfer of air from the inner volume to outside of the socket through the opening. The at least one vent element is separately formed from the socket body and discretely insertable into the opening and secured against the inner surface and the outer wall surface. A method and kit are provided to adapt the socket in a ventilated form.Type: ApplicationFiled: November 5, 2021Publication date: May 12, 2022Inventors: Sigurdur HANNESSON, Oskar Thor LARUSSON, Margret Sol RAGNARSDOTTIR, Dadi GRANZ

Publication number: 20170360580Abstract: A prosthetic knee includes a housing and a brake member pivotally connected to the housing at a first location point. The brake member defines a first pair of slots along a posterior surface of the brake member. A knee shaft extends through the brake member and is secured within a cavity defined by the housing. The knee shaft defines a second plurality of slots along a posterior surface of the knee shaft corresponding in location to the first slots. An extension assist system includes an extension assist link with a body portion and a plurality of arm portions situated in the first slots defined in the brake member and in the second slots defined in the knee shaft. The arm portions are pivotally connected to the knee shaft at a second location point located within the second slots and a distance from the first location point.Type: ApplicationFiled: September 1, 2017Publication date: December 21, 2017Inventors: Sigurdur Gisli KARLSSON, Sigurdur OLAFSSON, Sigurdur HANNESSON

Patent number: 9844448Abstract: A prosthetic knee for active users has a locking head generally parallel to a vertical axis of the prosthetic knee, a chassis, and a plurality of links connecting the locking head to the chassis. The knee includes a swing control mechanism having a flexion stop connected to the chassis and arranged to control the flexion angle of the knee. The flexion stop extends outwardly from the chassis and obliquely relative to the vertical axis. The knee has an audible feedback mechanism for providing the user with information about the location of the knee. The knee may also have a block lock forming a manually activated mechanism allowing load bearing in a flexed position.Type: GrantFiled: August 31, 2015Date of Patent: December 19, 2017Assignee: OSSUR HFInventors: Sigurdur Gisli Karlsson, Sigurdur Hannesson, Sigurdur Olafsson
