Abstract

A surgical fastener apparatus is provided with a reinforcement material holder, where the holder positions a sheet of reinforcement material adjacent body tissue that is sutured by a plurality of surgical staples dispensed by the apparatus.

Claims

1. A surgical fastener dispensing apparatus comprising:

a surgical fastener dispensing member on the apparatus that is operative to dispense at least one surgical fastener;

a surgical fastener receiving member on the apparatus that is positioned opposite the surgical fastener dispensing member and is operative to receive a surgical fastener dispensed from the surgical fastener dispensing member and to alter the surgical fastener received;

a reinforcement material holder on the apparatus that is positioned between the surgical fastener dispensing member and the surgical fastener receiving member;

reinforcement material that is removably mounted on the reinforcement material holder and is positioned between the surgical fastener dispensing member and the surgical fastener receiving member;

the reinforcement material holder having a pair of arms that are positioned at opposite sides of the surgical fastener receiving member for removably holding the reinforcement material on the pair of arms extending across the surgical fastener receiving member;

the reinforcement material having opposite side edges;

the pair of arms being removably attachable to the opposite side edges of the reinforcement material;

the pair of arms being a pair of elongate, narrow rods with one end of each rod being connected to the apparatus by a pivot connection for movement of each rod relative to the apparatus; and

,

the reinforcement material having a pair of openings that receive the pair of rods inserted into the openings in removably holding the reinforcement material on the pair of arms.

2. The apparatus of claim 1, further comprising:

the surgical fastener dispensing member having a dispensing surface with a plurality of fastener holes containing a plurality of surgical fasteners;

the surgical fastener receiving member having a receiving surface with a plurality of fastener contact areas that alter the surgical fasteners received by the surgical fastener receiving member; and

,

the reinforcement material holder holding the reinforcement material extending across the plurality of holes and across the plurality of fastener contact areas.

3. The apparatus of claim 2, further comprising:

a cutter that is movable across the surgical fastener receiving member and is positioned to cut through the reinforcement material removably mounted on the reinforcement material holder.

4. The apparatus of claim 1, further comprising:

a cutter that is movable across the surgical fastener receiving member and is positioned to cut through the reinforcement material removably mounted on the reinforcement material holder.

6. The apparatus of claim 1, further comprising:

the reinforcement material holder being permanently attached to the apparatus by a pivot connection and being movable to pivot with the reinforcement material relative to the surgical fastener dispensing member and relative to the surgical fastener receiving member.

5. A surgical fastener dispensing apparatus comprising:

a surgical fastener dispensing member on the apparatus that is operative to dispense at least one surgical fastener;

a surgical fastener receiving member on the apparatus that is positioned opposite the surgical fastener dispensing member and is operative to receive a surgical fastener dispensed from the surgical fastener dispensing member and to alter the surgical fastener received;

a reinforcement material holder on the apparatus that is positioned between the surgical fastener dispensing member and the surgical fastener receiving member;

reinforcement material that is removably mounted on the reinforcement material holder and is positioned between the surgical fastener dispensing member and the surgical fastener receiving member;

the reinforcement material holder having a pair of arms that are positioned at opposite sides of the surgical fastener receiving member for removably holding the reinforcement material on the pair of arms extending across the surgical fastener receiving member;

the reinforcement material having opposite side edges;

the pair of arms being removably attachable to the opposite side edges of the reinforcement material;

the pair of arms being a pair of elongate, narrow rods;

the opposite side edges of the reinforcement material having a pair of openings that receive the pair of rods inserted into the openings in removably holding the reinforcement material on the pair of arms; and

the reinforcement material having a pair of tubes with the pair of openings being to the pair of tubes.

7. A reinforcement for a surgical fastener dispensing apparatus having a surgical fastener dispensing member and a surgical fastener receiving member positioned on opposite sides of a reinforcement material holder, the reinforcement comprising:

a sheet of reinforcement material having a length between opposite end edges of the sheet and a width between opposite side edges of the sheet, the opposite side edges of the sheet being adapted for removable attachment to the reinforcement material holder of the surgical fastener dispensing apparatus;

the sheet of reinforcement material having a pair of tubes dimensioned to receive a pair of arms of the reinforcement material holder in removably attaching the sheet to the reinforcement material holder.

8. The reinforcement of claim 7, further comprising:

the length and width of the sheet of reinforcement material being dimensioned to cover over a plurality of fastener holes in the surgical fastener dispensing member.

9. The reinforcement of claim 7, further comprising:

the sheet of reinforcement material having a pair of openings dimensioned to receive a pair of arms of the reinforcement material holder in removably attaching the sheet to the reinforcement material holder.

10. The reinforcement of claim 7, further comprising:

the pair of tubes extending along the opposite side edges of the sheet.

11. The reinforcement of claim 7, further comprising:

the pair of tubes being parallel.
