Abstract

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.

First claim

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.

2 . The surgical kit of claim 1 , further comprising a clip applier cartridge, wherein the cartridge receiving assembly is operable to removably receive the clip applier cartridge, wherein the clip applier cartridge comprises:
(i) a clip, wherein the clip is configured to transition from an open configuration to a closed configuration, wherein the clip is configured to remain in the closed configuration upon transitioning from the open configuration to the closed configuration, (ii) a third drive assembly, wherein the third drive assembly is operable to drive the clip from the open configuration to the closed configuration, and (iii) a third input feature, wherein the third input feature is configured to couple with the movable output of the cartridge receiving assembly, wherein the third input feature is configured to actuate the third drive assembly in response to movement of the movable output.

3 .- 5 . (canceled)

6 . The surgical kit of claim 2 , wherein the third drive assembly comprises a pair of jaws and a collar, wherein the collar is configured to transition between a proximal position and a distal position, wherein the jaws are configured to close in response to longitudinal movement of the collar to thereby transition the clip from the open configuration to the closed configuration.

7 .- 8 . (canceled)

9 . The surgical kit of claim 6 , wherein the third drive assembly further comprises a rack and pinion assembly operable to drive the collar longitudinally.

10 . (canceled)

11 . The surgical kit of claim 2 , wherein the clip applier cartridge further comprises a plurality of clips, wherein the third drive assembly is operable to drive a succession of the clips from the open configuration to the closed configuration.

12 . The surgical kit of claim 11 , wherein the clip applier cartridge further comprises a retainer, wherein the retainer is operable to selectively retain one or more of the clips as the third drive assembly drives the succession of clips from the open configuration to the closed configuration.

13 . The surgical kit of claim 12 , wherein the third drive assembly further comprises a pair of jaws, wherein the jaws are configured to close in response movement of the third input feature to thereby transition the clip from the open configuration to the closed configuration.

14 . The surgical kit of claim 13 , wherein the retainer is configured to reciprocate longitudinally in response to movement of the third input feature to thereby successively index the clips in the succession relative to the jaws.

15 . The surgical kit of claim 14 , wherein the clip applier cartridge further comprises a rack and pinion assembly, wherein the rack and pinion assembly is configured to reciprocate the retainer longitudinally in response to rotary movement of the third input feature.

16 . The surgical kit of claim 1 , further comprising a grasper cartridge, wherein the cartridge receiving assembly is operable to removably receive the grasper cartridge, wherein the grasper cartridge comprises:
(i) a pair of grasping jaws, wherein the grasping jaws are configured to transition from an open configuration to a closed configuration, (ii) a third drive assembly, wherein the third drive assembly is operable to drive the grasping jaws from the open configuration to the closed configuration, and (iii) a third input feature, wherein the third input feature is configured to couple with the movable output of the cartridge receiving assembly, wherein the third input feature is configured to actuate the third drive assembly in response to movement of the movable output.

17 . The surgical kit of claim 16 , wherein the third drive assembly comprises a pair of links pivotably coupled with the pair of grasping jaws, wherein the links are operable to drive the grasping jaws from the open configuration to the closed configuration, wherein each of the links has a distal end and a proximal end, wherein the third drive assembly further comprises an actuator, wherein the distal end of each of the links is pivotably secured to a proximal end of a corresponding grasping jaw of the pair of grasping jaws, wherein the proximal end of each of the links is pivotably coupled with the actuator, wherein the actuator is configured to translate longitudinally in response to rotation of the third input feature to thereby drive the links.

18 .- 20 . (canceled)

21 . The surgical kit of claim 1 , further comprising a scissor cartridge, wherein the cartridge receiving assembly is operable to removably receive the scissor cartridge, wherein the scissor cartridge comprises:
(i) a pair of scissor blades, wherein the scissor blades are configured to transition from an open configuration to a closed configuration, (ii) a third drive assembly, wherein the third drive assembly is operable to drive the scissor blades from the open configuration to the closed configuration, and (iii) a third input feature, wherein the third input feature is configured to couple with the movable output of the cartridge receiving assembly, wherein the third input feature is configured to actuate the third drive assembly in response to movement of the movable output.

22 . (canceled)

23 . The surgical kit of claim 1 , further comprising a stapling cartridge, wherein the cartridge receiving assembly is operable to removably receive the stapling cartridge, wherein the stapling cartridge comprises:
(i) a plurality of staples, (ii)
