Abstract:
1. A hollow tissue inosculation apparatus to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins, comprising: 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, the curvature control mechanism substantially straightening the staple pins; and a gap control mechanism to control gaps of the hollow tissues with respect to the staple holder, the gap control mechanism reducing the gaps to cause the substantially straightened staple pins to penetrate the hollow tissues, the curvature control mechanism and the gap control mechanism being independent from each other; wherein the gap control mechanism includes two hollow tissue support mechanisms to support the two hollow tissues, respectively, and a mechanism to move the two hollow tissue support mechanisms in such a direction as to get closer to each other and in such a direction as to get away from each other.
