Distraction apparatus for plastic reconstruction of hand

Claim 1

A distraction apparatus for plastic reconstruction of a hand, comprising: at least two supports, a proximal support of said supports being made as a cramp-shaped plate carrying two parallel fixing pins secured at ends of said plate, and a distal support of said supports carrying distraction pins secured within the distal support with a possibility of longitudinal motion, as well as two distraction threaded rods on which the proximal support and the distal support are fitted so as to perform relative longitudinal motion, the fixing pins of the proximal support being arranged in a plane perpendicular with a plane of the cramp-shaped plate, the distal support being shaped as a bar having perforations spread along a longitudinal axis of the bar, said longitudinal axis of the bar being parallel to the plane of the cramp-shaped plate, additional distraction threaded rods being fitted in the perforations of the bar of the distal support with a possibility of individual longitudinal motion, said additional distraction threaded rods being directed towards the proximal support, distal ends of the distraction pins being fastened on proximal ends of the additional distraction threaded rods.

Claim 5

An apparatus as claimed in any one of the preceding claims, further comprising an additional fixing pin, the distraction threaded rods comprising two articulately interconnected portions, ends of the additional fixing pin being secured on respective distal portions of the distraction threaded rods.
