Abstract

A telescopic band applicator for use in applying an elastic band to a stump of tubular tissue includes an outer tubular member, a middle tubular member telescopically received within the outer tubular member, and an inner tubular member telescopically received within the middle tubular member. A plurality of concave prongs at the end of the inner tubular member are adapted and arranged to compress and capture the stump of tissue within the inner cylindrical surface of the middle tubular member for banding.

Claims

1. A telescopic band applicator for use in applying an elastic band to a stump of tubular tissue, comprising:

an outer tubular member, a middle tubular member telescopically received within the outer tubular member and having an inner cylindrical surface, and an inner tubular member telescopically received within the middle tubular member;

and a plurality of partially cylindrical prongs at the end of the inner tubular member adapted and arranged to compress and capture the stump within the inner cylindrical surface of the middle tubular member.

2. The applicator of claim 1 the prongs being arranged as first and second opposed pairs of identical prongs.

3. The applicator of claim 2 with each of the first pair of prongs having an inwardly facing forceps hook at a distal end thereof.

4. The applicator of claim 1 with each prong being formed in the shape of an elongated triangle being narrower at the end of the inner tubular member and wider at the opposing distal end of the prong.

5. The applicator of claim 4 with each prong having two elongated side edges and a short base edge at the distal end, and a forceps hook on the end of each of the first pair of prongs extending inwardly and perpendicularly from the short base edge.

6. The applicator of claim 1 with each prong having inner and outer concave surfaces, each outer concave surface having a degree of curvature approximately the same as the inner cylindrical surface of the middle tubular member, and each inner cylindrical surface being concentric with the outer cylindrical surface of a prong.

7. The applicator of claim 1 with the prongs having a predetermined width and elongated side edges of the prongs being tapered inwardly such that adjacent prongs imbricate as the inner tubular member is drawn into the middle tubular member to capture and compress a stump of tubular tissue within the interleaved prongs and draw it into the middle tubular member.

8. A telescopic band applicator for use in applying an elastic band to a stump of tubular tissue, comprising:

an outer tubular member, a middle tubular member telescopically received within the outer tubular member and having an inner cylindrical surface, and an inner tubular member telescopically received within the middle tubular member;

four prongs attached to an end of the inner tubular member, the prongs being arranged as first and second opposed pairs of identical prongs, each of the first pair of prongs having an inwardly facing forceps hook at a distal end thereof,

each prong being formed in the shape of an elongated triangle being narrower at the end of the inner tubular member and wider at the opposing distal end of the prong, with two elongated side edges and a short base edge at the distal end, the forceps hooks on the first pair of prongs extending inwardly and perpendicularly from the short base edge, and the forceps hooks having a length slightly in excess of the diameter of the middle tubular member inner cylindrical surface;

each prong having inner and outer concave surfaces, each outer concave surface having a degree of curvature approximately the same as the inner cylindrical surface of the middle tubular member, each inner cylindrical surface being concentric with the outer cylindrical surface of a prong; and

the prongs having a predetermined width, and the elongated side edges of the prongs being tapered inwardly, such that adjacent prongs imbricate as the inner tubular member is drawn into the middle tubular member to capture and compress a stump of tubular tissue within the interleaved prongs and draw it into the inner cylindrical surface of the middle tubular member.
