DEVICE FOR LIGATION IN MINIMALLY INVASIVE SURGERY WITH THREAD RESECTION OF TIGHT LOOP Russian patent published in 2008 - IPC A61B17/125 

FIELD: medicine; surgery.

SUBSTANCE: device for ligation in minimally invasive surgery with thread resection of a tight loop contains a catheter installed in the endoscope. The thread with a loop is installed in the catheter. The loop is placed from the operative side of the catheter. On the opposite side of the catheter there is a handle for moving and tightening the loop. Two parts of a resector with claw and groove are fixed in the operative end of the catheter. The parts are interlinked along the slope and have holes for the thread with sharp edges on the interlinked surfaces. One half of the resector with a claw is furnished with a cavity for the blocking device. The latter is located on the half of the resector with groove with possibility of taking the loop out from the cavity and resecting the thread of the tight loop by shifting the sharp edges of the holes.

EFFECT: reliable ligation of tubular structures; reliable resection of the thread with a tight one-piece unit; convenient work during ligation; reduced time of surgery operation and prevention from traumatising nearby organs and tissues.
