Description

for placement of the compression-distraction apparatus.

For the implementation of the method proposed tools that are interconnected by a single inventive concept

At the same time, in the cutting tool for the treatment of articular condo, made in the form of a chisel of an arcuate profile with P5gchka, the distinctive feature is that the chisel on a convex and concave surface has notches, and a hole is made in the handle.

Besides; The center finder is an aviCK with an arc-shaped slot and a hole in the center of the slot arc.

FIG. 1 shows the cutting tool for processing the articular ends, general view; in fig. 2 - centro-detector, general view; in fig. 3, section A-A in FIG. one. ,

 the tool is made in the shape of the chisel 1 of the arcuate profile with the handle 2. The chisel on the convex and concave surfaces has notches 3, and in the handle there is a hole 4 under the sapice 5. The price of the trisigal is a disk b with an arc-shaped slot 7 and a hole 8 in the center arc slotted.

The method is carried out as follows.

After opening the joint and placing its articular ends between them, a hollow half-cylinder of the bit 1 is inserted into the gap on the side of the joint so that its distal part is convex waxed into the concavity of one end of the joint and its concave part lies on the other end (proximal). Then the reciprocating movements of the bit 1 for its handle 2, the surgeon treats immediately the distal and proximal articular surfaces, cutting the bone and cartilage tissue into the desired veline.

Next, the tool remains in a fixed position on the newly formed joint, then on the end of the hollow half-cylinder of the bit 1 is put on an arcuate slot 7. The center-finder and through its hole 8 and hole 4 2 lead the needle of the distraction-compression apparatus.

Further, the distraction-compression apparatus is used to further develop the joints. .

The application of the method and device for its implementation allows to significantly improve the quality of treatment of joint ends, reduce the operative time and at the same time ensure accurate determination of the axis of flexion of the joint and the axial spoke of the distraction-compression apparatus.

Claims (3)

1. Method of preparing the joint for development, including the processing of the articular ends and holding the spokes along the flexion axis the joint is processed by exposing the joints of the ends and inserting the cutting tool into the joint slot so that its convex and concave parts match the joint and convexity of the joint, characterized in that with a chain of time reduction and precision, reciprocating movements Both articular surfaces are machined simultaneously with the cutting tool, then a centro-detector is placed on it coaxially with the cutting tool and a needle is drawn through the holes of the cutting tool and the prices of the three-cutter l accommodating compression-distraction device. 2. A cutting tool for processing the articular ends, made in the form of a chisel of an arched profile with a handle, characterized in that, in order to reduce time, the chisel on the convex and concave surfaces has notches, and a hole is made in the handle. 3. The center-finder, which is a disk with an arcuate slot and a hole in the center of the arc of the slot. Sources of information taken into account in the examination 1. Sivasch K.M.
