Abstract
A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, an incision mechanism to incise the hollow tissues, and a gap control mechanism to control gaps between the staple holder and the hollow tissues. The curvature control mechanism substantially straightens the staple pins. The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate through the hollow tissues. The staple holder prevents the ring member of the staple from expanding at least until the incision of the hollow tissues is completed.
