摘要：
The utility model is aimed at shortening the postoperative healing and the elimination of inflammatory complications in the use of the inventive prosthesis by providing its reliable fixation in the bone canal. Interphalangeal prosthesis brush comprises a distal and proximal articular legs connected by a hinge. The novelty of the claimed interphalangeal prosthesis brush is that the distal articular leg has the shape of a truncated cone with an apex angle of 11-13 degrees, the height of the distal articular legs of 7,0-12,0 mm, the lower base of the distal articular leg has a circular shape with diameter d1, from the lower base leg distal articular head has a diameter d1 and a thickness of 0.5-1.0 mm and the proximal articular leg has the shape of a truncated cone with an apex angle of 5-7 degrees, the height of the proximal articular legs compiled a 7,0-12,0 mm, the lower base of the proximal articular leg has a circular shape with a diameter d2, from the lower base leg proximal articular head has a diameter D2 and 0.5-1.0 mm thickness, proximal and distal legs are joint Central non-through hole, wherein the first 1-3 mm holes have a square cross section with a side of 1.5 mm, further openings have a circular cross section with a diameter of 1.5 mm, the total depth of holes of 3-6 mm, the hinge consists of a flexible part and two pins that are built into the flexible part of the hinge, with SET ovki them into non-through holes, the dimensions of pins correspond to the dimensions of non-through holes in the proximal and distal joint legs, the flexible part of the hinge has a flat surface located on the rear side of the hinge, and a concave surface located on the palm of the hinge side, the concave surface has a recess the arcuate shape, and two limiter at the edges of the external dimensions of the flexible hinge part is a parallelepiped.
