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, and a gap control mechanism to control gaps of the hollow tissues with respect to the staple holder. 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 the hollow tissues. The curvature control mechanism and the gap control mechanism are independent from each other.
