METHOD FOR IMPLANTING ELECTROMYOGRAPHIC ELECTRODES INTO STRIATED MUSCLES UNDER EXPERIMENTAL CONDITIONS Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: method involves immobilizing an animal after a period of fastening, fixing it with its cheek upward, shorn and shaved cheek is treated with 5% iodine solution in ethyl alcohol and layer-by-layer cutting tissues in the cheek area near the upper one-third of chewer muscle close to anterior edge under local transverse section anesthesia with 2% Novocain solution. Fascia is cut with 7 mm long incision in parallel to muscle fibers, separating the muscle fibers bluntly to build muscle pocket of 4mm x 4mm dimensions to which electrode is brought. Then, atraumatic needle is introduced into the muscle 2-3 mm proximal relative to muscle pocket apex and to the right and left of the muscle pocket. The needle is brought out through the pocket into the incision in the muscle. Needle pierce out is carried out through the muscle pocket 2 mm far from pierce in place. Electrode substrate is pulled in into the muscle pocket. Three isolated sutures are tied on muscle surface. Wires are brought out by means of trocar to cranium surface scalped in advance. The wires are soldered to standard connection unit and sealed with fast-hardening plastic.

EFFECT: high reliability of obtained experimental results.
