Embodiment Construction

[0061] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0062] figure 1 A possible example of an extramedullary alignment device / retention device for tibial resection guidance as provided by the present subject matter is shown in principle. The device is exemplarily (non-limitatively) composed / provided of: a telescoping rod 16, an ankle cuff affixed to the distal end of the telescoping rod 16, a bone saw / bone plate fixedly (non-detachably) affixed proximally The saw block 14 and the proximal alignment / probing device (stylus) 1 are preferably assembled at / on the bone saw plate 14 .

[0063] The alignment / probing device 1 is used for the tibial head. It generally has a probe 8 , an adjustment mechanism 6 for adjusting the distance between the probe 8 and the bone saw plate 14 , and an adjustment mechanism 4 for actuating the adjustment mechanism 6 .

[0064] By manually turning the adjustment mechanism 4 , for exam...

Abstract

The invention relates to a touch / orientation apparatus having, for orienting a saw template: an adjusting means; a moving means having a profiled indentation; a feeler, which is movable relative to the adjusting means; a scale for measuring the height of the adjusting means relative to the moving means; at least one first stop means, which is formed on the adjusting means; at least one second stop means, which is formed on the scale or acts as a scale, and which is provided and adapted to function as a resistance to the first stop means, the second stop means and / or the first stop means resiliently deflecting the other stop means.

Description

technical field [0001] The invention relates to a device or an alignment aid for aligning a bone saw plate or bone saw block for removal of the tibial head region (hereinafter referred to as tibial alignment aid) during implantation of a knee prosthesis. Background technique [0002] When implanting, for example, an artificial knee joint, the surgeon must use an oscillating bone saw to remove the defective bony portion of the tibial knee joint (tibial head, shin head). To this end, the surgeon uses an alignment device or alignment aid that enables him to affix a bone saw plate (also called a bone saw block) to the tibial head at the exact height and correct angular position relative to the tibia. [0003] At the beginning of implantation, the bone plate is retained on the tibial head by an extramedullary or intramedullary retention device with or without an alignment aid. In other words, retaining the bone plate can be performed extramedullary, i.e., by attaching the retain...
