GUIDE FOR LATARJET OPERATION Russian patent published in 2021 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to orthopedics, and can be used in open-ended operation of Latarjet. Guide for operation of Latarjet has handle and working part. Guide plate is a non-separable structure with hollow guides. Working part of guide consists of base, guiding device for articular process of blade, guides of cylinders for bone block and guide hole for provisory wire. Total length of guide makes 162.4 mm. Length of guide handle 130.4 mm, length of working part 32 mm, at 100.4 mm from beginning of working part handle has bend, which is 100-140°. Thickness of handle after bending towards working part is 5.60 mm, and width 16 mm, at that angle of inclination of working part relative to handle makes 120-150°. Along the handle rear surface there are grooves with radius of 0.85 mm to guide holes of the working part. Handle diameter extends from bend to handle beginning from 8 mm to 11.2 mm. Base has thickness of 5.6 mm and width of 12.35 mm; at the inlet holes of the cylinder guides there is a projection with radius of 1.5 mm at the base. Guide device for the articular process of the blade has the shape of a parabola with height of 27 mm and width of 16 mm, at that the thickness of parabola is 2.5 mm. Parallel to the rear part of the parabola there is a graduation scale of 10 to 24 mm with pitch of 1 mm. Guide cylinders are located at distance of 6 mm from each other and 6-8 mm from the guide device for the glenoid. Diameter of cylinders is 3.50 mm, are cannulated with hole diameter of 1.70 mm. Orifice for the tamper-operated wire is located between guide cylinders at equal distances from them of 3 mm and has diameter of 1.7 mm.

EFFECT: use of the invention makes it possible to facilitate positioning and installation of the instrument, to control the position, to ensure stability during the canal, to accurately visualize the bone block, to reduce the time of setting the pins to a greater depth and to provide different angles of inclination.
