<p>The proposed surgical instrument for stitching organs with the aid of metal staples in the "end-to-end", "end-to-side" and "side-to-side" methods, with the working part of the instrument disposed exeriorly of the organs being stitched, comprises two clamps each having two jaws for clinching and fixing the organs being stitched and pivotally interconnected at one end so that, when joined together, the joint line of the jaws of each clamp is perpendicular to the joint line of the clamps. The clamp jaws mount magazines with slots for staples, staple pushers, dies with recesses for bending the staples, as well as a device for aligning the organs being stitched longitudinallywith respect to the jaws, and a means for grasping the walls of the organs being stitched. The means for grasp ing the walls of the organs being stitched comprises cases with built-in toothed plates, said cases being mounted on each of the jaws in guides providing for a limited movability of each of said cases in a plane perpendicular to the joint line of the jaws and to the joint line of the clamps in such a manner that each of said cases may be set to either one of two extreme positions; with the cases set to one extreme position corresponding to the instant the walls of the organs being stitched are clamped and grasped, the tips of the plate teeth are disposed between the butt surfaces of the clamp jaws and a certain distance in front of the butt surfaces of the clamps in their set-apart condition, while, with the cases set to the other extreme position corresponding to the instant of organ suturing with the clamps being joined, the tips of the plate teeth lie a certain distance from the butt surfaces of the clamp jaws and approximately in the planes of the butt surfaces of the clamps.</p> |
