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; an incision mechanism to incise the hollow tissues, the staple holder preventing a ring member of the staple from expanding at least until the incision of the hollow tissues by the incision mechanism is completed; and a gap control mechanism to control gaps between the staple holder and the hollow tissues, the gap control mechanism reducing the gaps to cause the substantially straightened staple pins to penetrate through the hollow tissues.
