Device for the alignment research, alignment and orientation of prosthesis of the lower limbs

An adjustment setting device for alignment and angular orientation of a prosthetic device for a lower limb, the prosthetic device including an upper portion and a lower portion, said adjustment setting device comprising:

• first adjustment means, connected to said upper portion and having a lower spherical surface;
• second adjustment means, connected to said lower portion, and having an upper planar surface;
• third adjustment means positioned between, and coacting with, said first and second adjustment means, said third adjustment means including an upper spherical surface and a lower planar surface;
• the lower spherical surface of said first adjustment means and the upper spherical surface of said third adjustment means being relatively displaceable in three orthogonal planes to define means for angularly orienting said lower portion relative to said upper portion,
• the upper planar surface of said second adjustment means and the lower planar surface of said third adjustment means being relatively displaceable in two orthogonal planes to define means for aligning said lower portion relative to said upper portion in any direction in the plane of coaction of the planar surfaces and means for immobilizing said orienting means after said angular orientation has been set,
• whereby upon first setting said angular orientation of sad prosthesis upper and lower portions, alignment of said upper and lower prosthesis portions in orthogonal horizontal planes may be accomplished without a corresponding simultaneous change in position of the upper and lower portions in a third, vertical plane.
