PERFORATOR DEVICE Russian patent published in 2002 - IPC

FIELD: medical engineering. SUBSTANCE: device has body with cutting roller, supporting roller and driving unit. The driving unit is kinematically coupled with the supporting roller and cutting roller which longitudinal axes are parallel to each other and belong to a plane making an acute angle with the horizontal perforator base plane. Distance from the horizontal perforator base plane to the longitudinal cutting roller axis or the distance from the horizontal perforator base plane to the horizontal supporting roller axis is greater at least by 1/8 of the external diameter of the cutting roller than the distance from perforator base plane to the longitudinal axis of the cutting roller. The external supporting roller diameter mounted on greater distance from the horizontal perforator base plane is equal to at least 0.5 of the external roller diameter set on lesser distance from the horizontal perforator base plane. EFFECT: advantageous transplant positioning when setting it into the perforator device. 10 cl, 2 dwg
