Device for the positioning of a proximal extremity of a tibia against a cutting guide including an adjusting handle

Abstract

Equipment for the positioning of a proximal extremity of a tibia against a cutting guide (1), including a support bracket is shown. Devices are provided for distally immobilizing a tibia, which will immobilize the distal extremity of a tibia in a given position. These devices are mounted on the support bracket and can slide and be blocked in position following two directions perpendicular to the support bracket. It also includes devices (8, 9, 10, 11, 12, 13, 14) for proximally immobilizing a tibia which are mounted and can slide along the support bracket, a cutting guide (1) mounted on the support bracket frame, a gun handle (32) fixed to the support bracket, the hammer of which acts on devices (6) that enable the adjustment of the relative position of devices (8, 9, 10, 11, 12, 13, 14). This provides proximal immobilization with regard to the support bracket, the trigger of which acts on devices that enable the adjustment of the angle (posterior slope) between the support bracket and the tibia in the sagittal plane.
