Abstract
FIELD: medical engineering. ^ SUBSTANCE: device has movable branches with frame-shaped working members. The frame-shaped working members have pressure surfaces for holding tissues, branch stopper member and additional longitudinally movable and fixable member. The additional member is mounted in front of the working parts and is distinguished in that the branches are connected to each other allowing movement to meet each other or run in parallel. The additional member is shaped as spatula of special purpose design and has T- or L-shaped form or frame shape. The internal transverse dimensions of frame-shaped working members are not less than 0.3 mm greater than the maximum transverse size exceeding in this way the maximum auxiliary member. The pressure surfaces for holding the tissues are arch-shaped. ^ EFFECT: improved tissue engagement conditions. ^ 3 cl, 5 dwg
