A surgical kit includes an instrument and two or more cartridges. The instrument includes a body, a shaft assembly, and a cartridge receiving assembly. The cartridge receiving assembly has a movable output feature, which is configured to move in response to activation of the actuation input feature. The cartridges may include a first suturing cartridge and a second suturing cartridge, with first and second suture needles, respectively. The second suture needle may extend along an arc that has a larger radius of curvature than an arc associated with the first suture needle. The cartridges may also include a drive assembly that is operable to drive the needle along an orbital path in response to movement of the actuation input feature. The cartridges may also include features that are operable to apply clips or staples. The cartridges may also include features that are operable to grasp or cut. |

1. A surgical kit comprising:
(a) a surgical instrument, wherein the surgical instrument comprises:
(i) a body, wherein the body comprises an actuation input feature,(ii) a shaft assembly extending distally from the body, and(iii) a cartridge receiving assembly located at a distal end of the shaft assembly, wherein the cartridge receiving assembly comprises a movable output feature, wherein the movable output feature is configured to move in response to activation of the actuation input feature; (b) a first suturing cartridge, wherein the cartridge receiving assembly is operable to removably receive the first suturing cartridge, wherein the first suturing cartridge comprises:
(i) a first curved needle, wherein the first curved needle extends along an arc defined by a first radius of curvature,(ii) a first drive assembly, wherein the first drive assembly is operable to drive the first curved needle along an orbital path through a plurality of revolutions, and(iii) a first input feature, wherein the first input feature is configured to couple with the movable output of the cartridge receiving assembly, wherein the first input feature is configured to actuate the first drive assembly in response to movement of the movable output; and (c) a second suturing cartridge, wherein the cartridge receiving assembly is operable to removably receive the second suturing cartridge, wherein the second suturing cartridge comprises:
(i) a second curved needle, wherein the second curved needle extends along an arc defined by a second radius of curvature, wherein the second radius of curvature is larger than the first radius of curvature,(ii) a second drive assembly, wherein the second drive assembly is operable to drive the second curved needle along an orbital path through a plurality of revolutions, and(iii) a second input feature, wherein the second input feature is configured to couple with the movable output of the cartridge receiving assembly, wherein the second input feature is configured to actuate the second drive assembly in response to movement of the movable output. |
