METHOD OF PARACENTETIC TRANSDERMIC CHOLECYSTOTOMY AND DEVICE FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: medicine, for drainage of gallbladder at acute cholecystitis. SUBSTANCE: the method of paracentetic transdermic cholecystotomy consists in transdermic puncture of the gallbladder at monitoring by ultrasonic scanning. First, the gallbladder is punctured in the plane of ultrasonic scanning by a thin needle, and the contents is removed is removed through the needle duct; diagnostic manipulations are carried out and drugs or antiseptics are injected in the gallbladder cavity, the needle duct is obturated by mandrin, after which puncture and drainage of the gallbladder are accomplished in parallel with the thin needle is removed from the gallbladder. The device for cholecystotomy has a bracket with a guide to pass the puncture element, for example, the needle or trochar. The bracket uses a clamp for attachment of the ultrasonic scanning apparatus to the primary transducer, and a fork installed for turning in the plane of scanning and hinge-joined to the clamp with the aid of a hinge with a retainer of the fork angular position relative to the clamp; a bush is installed in the fork grooves for longitudinal movement and angular turn; at least two parallel to each other guide holes for the puncture elements are made in the bush in the plane of ultrasonic scanning. The fork is furnished with retainers of the bush longitudinal and angular positions. EFFECT: facilitated procedure. 2 cl, 2 dwg
