23 Jul Anti-impact bone implanted artificial limb
Abstract
The invention discloses an anti-impact bone implanted artificial limb, which belongs to the manufacturing technology of artificial limbs in biomedical engineering. The anti-impact bone implanted artificial limb consists of an implant, a midbody and an outer artificial limb, wherein one end of the implant is directly inserted into the inner cavity of a residual bone of an amputated limb. After surgery for one time or two times, the residual bone is combined with a soft tissue or skin, and the interface is healed, the midbody is connected to a skin extending end of the implant and is connected with the outer artificial limb. Therefore, an acceptation cavity used for transmitting motion and power for the traditional artificial limb is eliminated; and cacosmia caused by an acceptation cavity-residual limb interface environment and poor air permeability, infection of the residual limb caused by friction, limited limb movement range, and the limit that the artificial limb cannot be arranged on a disabled man whose residual limb is too short, in the traditional artificial limb, are substantially overcome. The anti-impact bone implanted artificial limb better accords with the biological movement rule of human limbs, and people with the artificial limb move as a normal man.
