Pallet for surgical stapling cartridge
View Patent ↗A means and method for inserting drivers into a surgical stapling cartridge, including a pallet that holds the cartridge firmly. The pallet has a central slot and laterally positioned lip members that are biased toward the slot. The cartridge is positioned in the slot and the lip members are released to extend their lips over the lateral flanges on the cartridge, thereby holding the cartridge in position. A finger extends into a recess formed at one end of the cartridge, thereby positively positioning the cartridge in the slot. The cartridge is released for removal by a tongue inserted between the lip members, thereby separating them by displacement.
1. A moveable pallet for firmly holding a surgical stapling cartridge as drivers are inserted therein, the pallet comprising:
(a) a base having a lower surface for seating on a conveyor, and an upper surface having an elongated cartridge region;
(b) a first cartridge-retaining lip member movably mounted to the base on a first side of the cartridge region, said first lip member being biased toward the cartridge region and having a lip extending from the lip member into the cartridge region; and
(c) a second cartridge-retaining lip member mounted to the base on a second side of the cartridge region, said lip member having a lip extending from the lip member into the cartridge region.
2. The pallet in accordance with claim 1 , wherein the cartridge region is an elongated slot formed between the lip members for holding the cartridge.
3. The pallet in accordance with claim 2 , wherein the second cartridge-retaining lip member is movably mounted to the base and biased toward the slot.
4. The pallet in accordance with claim 3 , further comprising a gap formed between the first and second lip members and adapted to receive a tongue that is inserted upwardly through an aperture in the base and seating against opposing surfaces of the lip members and displacing the lip members away from the slot.
5. The pallet in accordance with claim 3 , further comprising a finger mounted to the base near a first longitudinal end of the slot, said finger extending upwardly from the base for seating in a recess of said cartridge.
6. The pallet in accordance with claim 5 , wherein the lip members are slidably mounted within chambers formed in the base.
7. The pallet in accordance with claim 6 , further comprising chamber cover panels mounted to the base over the chambers, said chamber cover panels having upper surfaces.
8. The pallet in accordance with claim 7 , wherein said cover panel upper surfaces define seating surfaces for seating against stops and vertically positioning the pallet.
9. The pallet in accordance with claim 5 , further comprising at least one tapered cavity formed in the lower surface of the base for receiving a tapered tip and horizontally positioning the pallet.
10. A moveable pallet for firmly holding a surgical stapling cartridge as drivers are inserted therein, the pallet comprising:
(a) a base having a lower surface for searing on a conveyor;
(b) an elongated slot formed in an upper surface of the base for holding the cartridge;
(c) a first cartridge-retaining lip member movably mounted to the base on a first side of the slot, said first lip member being biased toward the slot and having a lip extending into the slot;
(d) a second cartridge-retaining lip member movably mounted to the base on a second side of the slot, said second lip member being biased toward the slot and having a lip extending into the slot;
(e) a gap formed between the first and second lip members and adapted to receive a tongue inserted upwardly through an aperture in the base, for seating against opposing surfaces of the lip members and displacing the lip members away from the slot; and
(f) a finger mounted to the base near a first longitudinal end of the slot, said finger extending upwardly from the base for seating within a recess of said cartridge.
11. The pallet in accordance with claim 10 , further comprising first and second chambers formed in the base on first and second sides of the slot, respectively, said first and second chambers housing the first and second lip members, respectively.
12. The pallet in accordance with claim 11 , further comprising at least one tapered cavity formed in the lower surface of the base for receiving a foot for positively positioning the pallet horizontally.
13. The pallet in accordance with claim 12 , further comprising at least one vertical registration surface for seating against at least two registration arms for positively positioning the pallet vertically.
14. The pallet in accordance with claim 13 , further comprising chamber cover panels mounted to the base over the chambers, wherein upper surfaces of the cover panels comprise said at least one vertical registration surface.
