Robotic loader 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 tool for picking up a frame to which a plurality of drivers for a surgical stapling cartridge is mounted, the tool comprising:
(a) a prime mover;
(b) a first finger drivingly linked to the prime mover, the first finger having a first pair of transverse planar panels formed in an inwardly facing surface of the first finger, the first pair of transverse planar panels adapted to seat against corresponding surfaces on the driver frame; and
(b) a second finger connected to the prime mover, the second finger having a second pair of transverse planar panels formed in an inwardly facing surface of the second finger that is substantially opposed to the inwardly facing surface of the first finger, the second pair of transverse planar panels adapted to seat against corresponding surfaces of the driver frame.
2. The tool in accordance with claim 1 , further comprising a first pair of substantially parallel planar panels intersecting the first pair of transverse planar panels near an end of the first pair of transverse planar panels.
3. The tool in accordance with claim 2 , further comprising a second pair of substantially parallel planar panels intersecting the second pair of transverse planar panels near an end of the second pair of transverse planar panels.
4. The tool in accordance with claim 3 , wherein the prime mover is an electromechanical transducer.
5. The tool in accordance with claim 3 , further comprising the frame to which the plurality of drivers is mounted, said frame being clampingly gripped between the first and second fingers.
6. A tool for picking up a frame to which a plurality of swing tabs for a surgical stapling cartridge is mounted, the tool comprising:
(a) a prime mover;
(b) a first finger drivingly linked to the prime mover, the first finger having a first pair of transverse planar panels formed in an inwardly facing surface of the first finger, the first pair of transverse planar panels adapted to seat against corresponding surfaces on the swing tab frame; and
(b) a second finger connected to the prime mover, the second finger having a second pair and a third pair of transverse planar panels formed in an inwardly facing surface of the second finger that is substantially opposed to the inwardly facing surface of the first finger, the second and third pairs of transverse planar panels adapted to seat against corresponding surfaces of the swing tab frame.
7. The tool in accordance with claim 6 , further comprising a fourth pair of transverse planar panels formed in an inwardly facing surface of the first finger, the fourth pair of transverse planar panels adapted to seat against corresponding surfaces on the swing tab frame.
8. The tool in accordance with claim 7 , further comprising a first pair of substantially parallel planar panels intersecting the first and fourth pairs of transverse planar panels near an end of the first and fourth pair of transverse planar panels.
9. The tool in accordance with claim 7 , further comprising a second pair of substantially parallel planar panels intersecting the second and third pairs of transverse planar panels near an end of the second and third pairs of transverse planar panels.
10. The tool in accordance with claim 9 , wherein the prime mover is an electromechanical transducer.
11. The tool in accordance with claim 9 , further comprising the frame to which the plurality of swing tabs is mounted, said frame being clampingly gripped between the first and second fingers.
12. The tool in accordance with claim 9 , wherein the first and second fingers are forked to form legs, each of which has one of said pairs of transverse panels formed therein.
