Than that described above, the outer staple (that is, from the row that passage 243 is farthest) in storehouse 240 can be in interior staple (that is, from passage 243 Nearest row) before.In other words, the deformation of the nail in outboard row can or the most slightly laterally adjacent in inboard row Start before the deformation of nail.In other instances, the outer staple (that is, from the row that passage 243 is farthest) in storehouse 240 can fall behind interior staple (that is, from the row that passage 243 is nearest).In other words, the deformation of the nail in inboard row can or the most slightly in outboard row Start before the deformation of laterally adjacent nail.Although additionally, two staples are disclosed in each of the passage 243 that is limited in storehouse 240 On side, but it is envisioned that go out other realities that wherein more than two staple (the most such as three staples) is present on each side of passage 243 Execute scheme.In this type of embodiment, sliding part be configured to interior staple simultaneously and outer staple simultaneously and/ Or dispose other staple in the time sequentially carried out relative to interior staple and outer staple.
As it has been described above, the first sliding part part 792 can be relative to the second sliding part part 793 of sliding part 790 Motion.Referring now to Figure 70 to Figure 72, sliding part 790 can initially, do not fire configuration (Figure 70) and second, stretch out structure Move between type (71 and Figure 72).Sliding part 790 initial, do not fire in configuration, referring especially to Figure 70, first slide Part part 792 is collapsed in Part II 793 or bounces back relative to Part II 793.In at least one this type of example, first The distal end of sliding part part 792 may not extend over the distal end of the second sliding part part 793.At other example In, although not shown, but when the first sliding part part 792 is collapsed in Part II 793, the first sliding part part 792 Distal end can extend over the distal end of the second sliding part part 793.With further reference to Figure 70, reader will manage further Solving, nail 460 is in non-firing position when it not yet promotes towards anvil block 124.After contrast Figure 70 and Figure 71, reader will note that Arriving, the first sliding part part 792 extends relative to the second sliding part part 793.In this case, the first sliding part part The distal end of 792 positions towards distally relative to the distal end of the second sliding part part 793.First sliding part part 792 from Its initially, the motion of non-firing position to its extended position can by interior ramp portion 791a of the first sliding part part 792 and/or Outslope part 791b is positioned at below one or more nail 460.In other configuration, the first sliding part part 792 is from the beginning of it Begin, interior ramp portion 791a and/or outslope part 791b can not be positioned at by the motion of non-firing position to its extended position Below one or more nails 460.In any case, as shown in Figure 71, the extension of the first sliding part part 792 can be towards anvil block 124 promote at least one nail 460 at least in part and/or make at least one nail 460 deform at least in part against anvil block 124. In some instances, the extension of the first sliding part part 792 can promote at least one nail 460 completely or make at least one nail 460 It is badly deformed against anvil block 124.In all cases, when the first sliding part part 792 moves in its extended position, second Sliding part part 793 can not advance towards distally；But, in some cases, stretch out when the first sliding part part 792 moves to it Time in position, at least some distal movement of the second sliding part part 793 can occur.
After contrast Figure 71 and Figure 72, it is also important to note that the first sliding part part 792 and the second sliding part part 793 court Distally advances, to promote nail 460 towards anvil block 124.First sliding part part 792 and the second sliding part part 793 can push away subsequently Entering the distal end of end effector 120, to complete the percussion stroke of end effector 120, this percussion stroke will below In discuss in more detail further.In any case, sliding part 790 is during the percussion stroke of end effector 120 Initial advance be shown in Figure 70 to Figure 72.Figure 70 shows the sliding part 790 being in retraction, non-firing position；Figure 71 Show be in stretch out, the sliding part 790 of part firing position；And Figure 72 show be in stretch out, firing position Sliding part 790.As it has been described above, one or more pusher bar 159 can be towards distal movement, in order to by Figure 70 to Figure 72 institute Come in advance sliding part 790 before showing.With reference to Figure 70, pusher bar 159 is shown in wherein itself and the first sliding part portion Divide the firing position initial, non-of the proximal end contact of 792.In various embodiments, pusher bar 159 can include from it remote The contact flange 155 that side end extends, contacts the engageable first sliding part part 792 of flange 155.With further reference to Figure 70, when Pusher bar 159 be in its initially, non-firing position time, pusher bar 159 can not contact with the second sliding part part 793.When When pusher bar 159 advances towards distally, pusher bar 159 can make the first sliding part part 792 towards distal movement, until contact convex Edge 155 contacts, as shown in Figure 71 with the proximal end of the second sliding part part 793.First sliding part part 792 and second just This relative motion between sliding part part 793 makes sliding part 790 extend, as discussed above.Then, pusher bar 159 can advance towards distally, in order to advance the first sliding part part 792 and the second sliding part part 793 towards distally, such as Figure 72 simultaneously Shown in.
As discussed above, end effector 120 is configured to sew up and transecting patient tissue simultaneously.Referring again to figure 65, end effector 120 can include that firing member or knife bar 156, firing member or knife bar 156 include the edge of a knife 158, this edge of a knife quilt It is constructed to be permeable to the transecting patient tissue when knife bar 156 advances towards distally.Referring again to Figure 70 and Figure 71, one or more pusher bar The initial distal movement of 159 can be not passed to knife bar 156.In other words, knife bar 156 can keep static or the most quiet Stop, and sliding part 790 moves between its advanced position (Figure 70) and its extended position (Figure 71).In this case, At least during the initial part of end effector percussion stroke, the relative fortune between pusher bar 159 and knife bar 156 can occur Dynamic.After contrast Figure 74 and Figure 77, it can be seen that one: pusher bar 159 advances so that sliding part 790 towards distally Extend, and its two: knife bar 156 not yet towards distally advance.Knife bar 156 and the proximal end of pusher bar 159 can be paid special attention to. More particularly, pusher bar 159 may be included in the drive pin 759 extended between them, and it is narrow that drive pin 759 extends through driving Groove 757, drives slit 757 to be limited to from the drive rod 157 that knife bar 156 proximally extends.When pusher bar 159, to be in it near During the non-firing position in side, as shown in Figure 74, during drive pin 759 is positioned at the proximal end driving slit 757.Work as pusher bar 159 when advancing towards distally, and as shown in Figure 77, drive pin 759 can slide towards distally in driving slit 757, until drive pin 759 Arrive the distal end driving slit 757.In this type of position, sliding part 790 is the most fully extended and knife bar 156 not yet with push away Dynamic device bar 159 advances towards distally together.Once drive pin 759 contacts, such as Figure 78 and Figure 79 with the distal end driving slit 757 Shown in, then pusher bar 156 and knife bar 159 can together with advance towards distally.
Than that described above, knife bar 156 can include that flange 153 and 155, flange 153 and 155 are configured to connect respectively Close anvil block 124 and staple cartridge channel 123.When knife bar 156 is in its nearside, does not advances position, as shown in Figure 77, flange 153 can Proximally position relative to the slit 121 being limited in anvil block 124.In this type of position of knife bar 156, flange 155 both can be determined Position also can delocalization in the outside being limited to storehouse passage 123 and/or in slit in.When knife bar 156 advances towards distally, Flange 153 can enter anvil slot 121 and flange 155 can be positioned in the passage slot of storehouse.In this case, knife bar 156 The gap between anvil block 124 and the nail bin being positioned in storehouse passage 123 or interstice's distance can be set.In all cases, When knife bar 156 advances towards distally, knife bar 156 can control to be organized in the forming height in end effector 120 and/or compression.
Wherein before pusher bar 159 advances cutter 158, pusher bar 159 makes the above-mentioned cloth that sliding part 790 moves The mode of putting can be favourable in many cases.Such as, it is often necessary to before incision tissue, sew up tissue, and therefore, follow closely Formation cause or the most enough cause knife bar 156 transecting patient tissue.The staggered deployment of sliding part 790 and knife bar 156 can be conducive to This type of between nail shaping with tissue incision advances relatively.Additionally, sliding part 790 can bounce back with it, not fire configuration compact ground It is stored in end effector 120, in order to allow the shorter nearside of end effector 120 to distal length or longitudinal length. In other words, the sliding part that can start its percussion stroke under at least part of collapsed state may need less the most empty Between.Additionally, such as, due to longitudinal extensibility of sliding part 790, therefore compared with the sliding part of one, sliding part group The nail of part 790 promotes surface can be longer and can include more shallow or the most sharp-pointed ramp angle.In other words, sliding part The mechanical advantage of 790 can be improved because being available for the longer longitudinal length on the slope of sliding part 790.
Can be towards distally towards end effector 120 referring now to Figure 80 to Figure 82, sliding part 790 and knife bar 156 Distal end advances, to complete the percussion stroke of end effector 120.When sliding part 790 is close to the distally of end effector 120 During end, in various examples, the first sliding part part 792 can contact the distal end 245 of nail bin and slide relative to second Follower portion 793 and/or in the second sliding part part 793 bounce back.More specifically, distal end 245 can stop the first slip The distal movement of part part 792, and the second sliding part part 793 relative to the first sliding part part 792 towards distally advance so that Complete to fire stroke.In various examples, the second sliding part part 793 can advance towards distally, until it also contacts the remote of nail bin Side end 245, and in other instances, percussion stroke can be complete before the second sliding part part 793 contacts distal end 245 Become.In any one situation, the distal lip 155 of pusher bar 159 pushes away towards the distal end of end effector 120 wherein In the embodiment of dynamic first sliding part part 792 and the second sliding part part 793, when the first sliding part part 792 arrives far During side end, the first sliding part part 792 can be changed into and is disengaged with pusher bar 159 so that pusher bar 159 can be relative to First sliding part part 792 promotes the second sliding part part 793.In at least one this type of example, referring especially to Figure 77, nail bin Distal end can include boss 241, this boss is configured to promote the first sliding part part upwardly toward anvil block 124 792 so that pusher bar 159 can be in the first sliding part part 792 slid underneath.In this case, the first sliding part part 792 and second sliding part part 793 and pusher bar 159 be operatively disengaged from joint.In various examples, boss 241 can quilt After being positioned and arranged to so that the most having disposed and/or be transferred to the second sliding part part 793 at all nails of nail bin, first is sliding Follower portion 792 is lifted up, as discussed above.Additionally, than that described above, the distal end of nail bin can include the first boss 241 and second boss 241, the first boss 241 is configured to promote the first sliding part part 792, and the second boss 241 is by structure Cause and can promote the first other sliding part part 792.In various examples, boss 241 is configured to the most same Step ground promotes the first sliding part part 792.In some instances, boss 241 is configured to sequentially promote the first cunning Follower portion 792.
Illustrate referring now to Figure 85 to Figure 88, Figure 85 be in its initially, do not fire the sliding part 790 of configuration.Except upper Beyond stating, pusher bar 159 can contact the proximal end 789 of the first sliding part part 792 and promote the first sliding part towards distally Part 792, until the proximal end 789 of the first sliding part part 792 is neat with the proximal end 787 of the second sliding part part 793 Flat, as shown in Figure 86.Herein, the first sliding part part 792 can be fully extended relative to the second sliding part part 793.Then, Pusher bar 156 can simultaneously advance proximal end 787 and proximal end 789, to advance sliding part 790 towards distally.The most such as As discussed above, referring now to Figure 87, such as, the first sliding part part 792 can be stopped and by following closely by the distal end 245 of nail bin The boss 241 in storehouse is lifted up.Herein, the first sliding part part 792 can be convex relative to the second sliding part part 793 and distally Edge 155 raises so that the second sliding part part 793 can be relative to the first sliding part part 792 and at least in part first Sliding part part 792 slid underneath, in order to make sliding part 790 collapse, as shown in Figure 88.After contrast Figure 87 and Figure 88, It can be seen that the second sliding part part 793 is moved towards the chimb 788 in the basal surface being limited to the first sliding part part 792 Must be closer to, and the distal end 789 of the first sliding part part 792 no longer with the distal end of the second sliding part part 793 787 alignment.
After percussion stroke completes, can be proximally referring now to Figure 83 and Figure 84, knife bar 156 and pusher bar 159 Retraction.In all cases, knife bar 156 can be by pusher bar 159 proximally tractive.More specifically, pusher bar 159 can be relative Proximally bounce back in knife bar 159, until drive pin 759 contact drives the proximal end of slit 759.Herein, pusher bar 159 Can proximally tractive knife bar 156, until the flange 153 of knife bar 156 is no longer positioned in the slit 121 of anvil block 124.Then, when When Guan Bi pipe 115 is by proximally tractive, anvil block 124 is moveable in its open position.In some instances, can include can for nail bin The nail bin replaced.In such instances, the nail bin being finished can remove from storehouse passage 122, and if it is required, unspent nail bin Can be positioned in storehouse passage 122 so that surgical instruments can reuse.
