Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A surgical apparatus for suturing soft tissues, comprising: two guides interhinged at one end; a tie spring between the guides which normally maintains the guides at the other end in a spaced-apart position; a magazine for storing a plurality of Ushaped suturing staples therein disposed at the free end of one of the guides; a pusher adapted to slide along said latter guide for ejecting the staples from said magazine points first; twin needleshaped dies disposed on the free ends of said guides for seizing therebetween, as the guides are brought together, the tissue to be staple-sutured; a means for controlling said magazine by displacing the magazine and feeding new staples to the working position; a means for cutting the vessels and ducts of said tissue being sutured in the area between said applied staples, said vessel-cutting means being disposed on the free ends of said guides; and a member for detaching the vessels and ducts located outside of the suturing and cutting zone, said member being disposed on the free end of one of the guides.
Claim 2
Dependent Claim
177 words
A surgical apparatus for suturing soft tissues, comprising: two guides interhinged at one end; a tie spring between the guides which normally maintains the guides at the other end in a spaced-apart position; a magazine for storing a plurality of Ushaped suturing staples therein disposed at the free end of one of the guides; a pusher adapted to slide along said latter guide for ejecting the staples from said magazine points first; twin needleshaped dies disposed on the free ends of said guides for seizing therebetween, as the guides are brought together, the tissue to be staple-sutured; a means for controlling said magazine by displacing the magazine and feeding new staples to the working position; a means for cutting the vessels and ducts of said tissue being sutured in the area between said applied staples, said vessel-cutting means being disposed on the free ends of said guides; and a member for detaching the vessels and ducts located outside of the suturing and cutting zone, said member being disposed on the free end of one of the guides.
Claim 3
Dependent Claim
128 words
The apparatus as claimed in claim 1, wherein the tissue-cutting means is provided by two cooperating knives, one of which, defined by a plate, is fixed on the end of the guide which carries the member for detaching vessels and ducts, while the other knife, a movable member, is defined by a lever with a cutting edge mounted on the other guide and normally spring-loaded so that the cutting edge is withdrawn from the immovable cutting edge, and the distal end of the lever is Provided with a projection which cooperates with the staple pusher so that, as the pusher is executing a backward movement, the knife lever turns against the action of the spring, thus causing the two knives to be brought together and cut the tissue.
Claim 4
Dependent Claim
104 words
The surgical apparatus as claimed in claim 1, wherein the staple pusher is provided with a lever member boosting the pushing action at the instant staples are bent, which member is defined by an L-shaped lever interhinged with the rear end of the pusher so that one comparatively long arm of the lever is adapted to be hand-moved along one guide together with the pusher, while the other guide includes a stop cooperating with the other arm of the lever, when the long arm of the lever is completing the movement thereof, whereupon the lever turns, exerting an additional pushing effort on the pusher.
Claim 5
Dependent Claim
61 words
The surgical apparatus as claimed in claim 1, wherein the member for detaching vessels and ducts is defined by an L-shaped plate or gib secured flush with plate of the immovable knife between the protruding ends of the needle-shaped dies which are rounded at the tips, just as the latter L-shaped plate or gib, lest vessels and ducts be pierced thereby.
Claim 6
Dependent Claim
55 words
The surgical apparatus as claimed in claim 2, wherein the pusher portion which cooperates with the projection on the distal end of the movable knife for turning the same, is defined by a separate countersinking stop, so that with the latter stop in a sunk position the pusher is barred from cooperating with the knife.
