    • A prosthetic foot includes an adapter element securable to a residual limb, a foot plate having a heel portion and a toe portion along the length thereof, at least one toe spring connected between the adapter element and the toe portion of the foot plate, and a heel spring connected between the adapter element and the heel portion. The heel spring may be a leaf spring or a tube type shock absorber. The concave side of the leaf spring exhibits a plurality of transverse ribs. Alternatively, a tubular pylon may have a collar mounted thereon for movement along the length of the pylon. A toe spring and a heel spring extend from the collar to form toe and heel portions of the prosthetic foot. A further heel spring is connected between the heel portion and another end of the pylon, and a non-extensible band extends between the heel portion and the collar. As another alternative, a tubular pylon has one end securable to a residual limb, and a collar is mounted to the pylon for movement along the length of the pylon. At least one toe spring is connected between the collar and the toe portion of a foot plate, while a heel spring is connected between the heel portion of the foot plate and another end of the pylon.
    • 辅助脚包括可固定到残肢的适配器元件,具有脚跟部分的脚板和沿其长度的脚趾部分,连接在适配器元件和足板脚趾部分之间的至少一个趾形弹簧,以及 脚跟弹簧连接在适配器元件和跟部之间。 脚跟弹簧可以是板簧或管式减震器。 板簧的凹面呈多个横向肋。 或者,管状塔架可以具有安装在其上的轴环,用于沿着塔架的长度移动。 脚趾弹簧和脚跟弹簧从套环延伸以形成假脚的脚趾和脚跟部分。 后跟弹簧连接在脚跟部分和塔架的另一端之间,并且不可延伸的带在脚后跟部分和颈圈之间延伸。 作为另一替代方案,管状塔架具有一个可固定到残肢的端部,并且将套环安装到塔架上以沿着塔架的长度移动。 至少一个脚趾弹簧连接在脚踏板的凸缘和脚趾部分之间,而脚跟弹簧连接在脚踏板的后跟部分和挂架的另一端之间。

    • A system and method for releasably securing a prosthetic limb to a residual limb. The system and method utilizes a lanyard for drawing the residual limb into a receiving portion of the prosthetic limb and for helping to maintain attachment of the prosthetic limb to the residual limb. The lanyard is routed through a releasable ratchet mechanism, which allows tension to be incrementally applied to the lanyard and further prevents the lanyard and the residual limb connected thereto from moving in an opposite direction. A suction cup may also be employed within the receiving portion of the prosthetic limb for aiding in retention of the residual limb. The ratchet mechanism allows the system to be used without maintaining constant tension on the lanyard, thereby reducing the amount of effort required of the user. The system and method also reduces or even eliminates pistoning of the residual limb within the prosthetic limb during movement of the user.
    • 用于将假肢可释放地固定到残肢的系统和方法。 该系统和方法利用挂绳将剩下的肢体拉到假肢的接受部分中并帮助维持假肢与残肢的连接。 挂绳穿过可释放的棘轮机构,其允许张力被递增地施加到挂绳上,并且进一步防止连接到其上的系索和残肢沿相反方向移动。 也可以在假肢的接收部分内使用吸盘来辅助残留肢体的保留。 棘轮机构允许使用系统而不保持挂绳上的恒定张力,从而减少用户所需的努力。 该系统和方法还减少或甚至消除使用者移动期间肢体肢体残留肢体的活动。
