FIELD: medicine.
SUBSTANCE: invention relates to medicine. Inducer for introduction of circular sewing instrument into patient's includes hollow flexible envelope. Flexible envelope has distal end and open proximal end, size of which makes it possible to store part of sewing head of circular sewing instrument. Rigid cap unit can be fixed to distal end of hollow flexible envelope. Rigid cap unit can be made with possibility of selective travel between closed position, in which distal surface of sewing head is covered, and open position, in which distal surface of sewing head is open.
EFFECT: part of rigid cap unit has shape, in fact, copying shape of perimeter of part of sewing head, which makes it possible for rigid cap unit to pass proximally through sewing head when introducer is being removed from patient's organism.
