ABSTRACT:
The two-part surgical fastener is composed of an annular stapling part having projecting prongs and an annular retaining part having an annular gap which receives the prongs. The anvil assembly on which the retaining part of the fastener is mounted has fingers which can be collapsed radially inwardly after stapling to permit ease of removal. During stapling, the annular stapling part is driven through the tubular ends of the tissue into retained engagement with the retaining part. At the same time, the clamped ends of the tissue are cut on a circular line and, thereafter, the anvil assembly is collapsed radially inwardly to permit withdrawing of the stapling apparatus.
