METHOD distal locking intramedullary nail in the osteosynthesis of long bones AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method of locking rods at the distal intramedullary osteosynthesis of long bones, comprising a closed reposition bone fragments of a long bone, the introduction into the medullary canal cannulated intramedullary rod of a predetermined length, for the formation of locking screws in bone biological tissue tubular bone holes which coincide with an upper and downstream holes at the working end of the intramedullary rod, and the introduction of controlled via inhibiting the K-wire their screws through holes formed, characterized in that after introduction into the medullary canal cannulated intramedullary rod of a predetermined length in a longitudinal bore of the intramedullary rod with the acousto-optical waveguide is introduced laser tip at its distal end; rotates between the mechanical and optical soyustirovku transceiver aperture acousto-optic laser tip with the perpendicular passing through the center of the downstream openings of the working end of the intramedullary rod and lowered to the plane in which lies the hole, which is irradiated with the downstream opening of the working end of the intramedullary rod measuring pulsed laser signal wavelength λ1, is received by the scattered radiation receiver measuring pulsed laser signals at the wavelength λ1 wavelength and are formed in a circumferential dimensional Fourier image Ir (x, y) opening downstream of the working end of the intramedullary rod determines the distance from the exit aperture of the two-frequency priemoperedayuscheg
