Abstract
A limb prosthesis which via coupling means is adapted to be connected to an implant in the form of an osseointegrated shaft projecting from an amputated stump. The coupling means comprises a flexible joint and the prosthesis further comprises at least one force transmitting device secured to and extending from a prosthetic member connected to the coupling means up to a position on the amputated stump or body portion to which the stump connects. The force transmitting device is adapted to be secured to the stump or other body portion in such a way that it relieves the implant from at least part of the bending and/or rotational forces exerted to the prosthetic member.
Claims10
A limb prosthesis which via coupling means is adapted to be connected to an implant in the form of an osseointegrated shaft projecting from an amputated stump, wherein a prosthetic member defines an upper terminal end of said limb prosthesis, wherein said coupling means comprises a flexible joint adapted to permit tilting of said implant with respect to the prosthetic member in one, more, or all directions, wherein a force transmitting device is secured to and extends from the prosthetic member up to a position on the amputated stump or body portion to which the stump connects, said force transmitting device comprises a socket adapted to accommodate the stump, said socket having one end portion secured to the prosthetic member and an opposite end portion secured around at least a substantial part of the circumference of the stump or other body portion, wherein the two end portions of the socket are interconnected by at least one rigid arm member, and wherein the implant is allowed to tilt with respect to the socket and to the prosthetic member so that the implant is relieved from at least part of the bending forces exerted to the prosthetic member.
A limb prosthesis having a prosthetic member leading to a prosthetic joint, said prosthetic member being connected by a coupling means to an implant in the form of an osseointegrated shaft projecting from an amputated stump, said coupling means comprising a first coupling member secured to a free end of said osseointegrated shaft, and a second coupling member secured to said prosthetic member, said first and second coupling members being interengaged and movable with respect to each other in a manner permitting said implant to tilt with respect to said prosthetic member in one, more or all directions, and a force transmitting device secured to and extending from said prosthetic member up to a position on the amputated stump or body portion to which the stump connects, said force transmitting device comprising a socket adapted to accommodate the stump, said socket having one end portion secured to said prosthetic member and an opposite end portion secured around at least a substantial part of the stump or other body portion, wherein the two end portions of the socket are interconnected by at least one rigid arm member, and wherein said implant is allowed to tilt with respect to the socket and to the prosthetic member.
A limb prosthesis adapted to be connected to an amputated stump having an implant in the form of an osseointegrated shaft projecting therefrom, said limb prosthesis comprising:
- a prosthetic member defining a terminal upper end of said limb prosthesis;
- a force transmitting device secured to and extending from said prosthetic member up to a position on the amputated stump or body portion to which the stump connects, said force transmitting device comprising a socket adapted to accommodate the stump, said socket having one end fixed to said prosthetic member and an opposite end secured around at least a substantial part of the stump or other body portion, with at least one rigid arm member connecting the two ends of said socket;
- and
- coupling means for connecting said osseointegrated shaft to said prosthetic member, said coupling means comprising a first coupling member secured to a free end of said osseointegrated shaft and a second coupling member secured to said prosthetic member, said first and second coupling members being interengaged and movable with respect to each other in a manner permitting said osseointegrated shaft to tilt with respect to said prosthetic member and said force transmitting device in one, more or all directions.
