As discussed above, being trapped in the tissue between the anvil block of surgical end-effector and nail bin can exist during use Moved in end effector or flowed relative to end effector.Also as discussed above, this motion or flowing can hold in end The firing member of row device is moved when store the nail in nail bin with can removing and cut tissue firing as substantially remote towards distally Side.If firing member is proximally moved, then the motion organized or flowing may be substantially nearside.Even so, tissue Distally flowing can make during percussion nail towards distally shift.This phenomenon figure 30 illustrates.Figure 30 is shown from being defined in The nail 2630 of the ejection of nail cavity 2650 in warehouse 2610.Nail 2630 is shown at least part of firing position, in the position, The base portion 2631 of nail 2630 is just moved upwards by staple drivers 2640 towards anvil block 20, and in the position, the leg of nail 2630 2632a, 2632b have been ejected from nail cavity 2650 and have been contacted anvil block 20.As reader will appreciate that, nail cavity 2650 may include to be constructed It is adapted into the first protuberance 2651a and the first end wall 2652a that can support the first nail leg 2632a and similarly It is enough follow closely 2630 ejected from nail cavity 2650 by driver 2640 when support the second protuberance 2651b and the of the second nail leg 2632b Two side wall 2652b.However, as shown in figure 30, nail 2630 can during percussion towards distally shift so that nail leg 2632a away from First end wall 2652a is shifted and nail leg 2632b is shifted on the second protuberance 2651b.Although nail 2630 is shifted towards distally, First leg 2632a has still been received in the first forming cup 22a of the nail pit being defined in anvil block 20 and the second leg 2632b Still receive in the second forming cup 22b of nail pit.Although nail leg 2632a, 2632b can contact its correspondingly configured cup 22a, 22b, but nail 2630 distally displacement may not cause to be symmetrically staple for example shown in Figure 31.Figure 31 is shown and driven by nail Device 2640 is improved to greater than the position of the storehouse platform surface 2611 of warehouse 2610 and is deformed into the nail 2630 of its complete firing configuration.

As discussed above, symmetrical nail can asymmetrically deform because being trapped in the tissue displacement in end effector. In all cases, for example available asymmetric nail that can compensate for this displacement of nail bin, such as shown in Figure 24 and Figure 27 to Figure 29 Asymmetric nail.The nail leg of these asymmetric nails can be configured so that in this way when it is asymmetric nail shifted towards distally when, it Displaceable into the orientation that them can be caused to be deformed into symmetrical or at least more symmetrical percussion configuration.Figure 84 is shown including warehouse 4810 nail bin 4800, the warehouse include be defined in multiple nail cavities 4850 therein, be positioned at it is asymmetric in nail cavity 4850 Follow closely and be configured to that the multiple drivers 4840 ejected from nail cavity 4850 will be followed closely.Warehouse 4810 may include distal end 4813 and proximal end 4816, wherein nail cavity 4850 can be arranged to the longitudinal direction row being defined in warehouse 4810.Warehouse 4810 exists By transversal in such mode in Figure 84 so that show such longitudinal nail chamber 4850.In some cases, can remove ground Storing the nail in longitudinal nail chamber 4850 can have the asymmetric configuration of identical, and in other cases, as shown in Figure 84, nail There can be different asymmetric configurations.For example, follow closely 4830' storages follows closely 4830 in the longitudinally proximal end of row " store vertical In distal end to row.Similar to above-mentioned, each nail 4830' may include the first nail leg 4832a' and the second nail leg 4832b', One of wherein described nail leg or both for example may include some fragments, the such as fragment of the second nail leg 4832b' 4833b' and 4834b'.It is also similar to above-mentioned, each nail 4830 " may include the first nail leg 4832a " and the second nail leg 4832b ", One of wherein described nail leg or both for example may include some fragments, such as the first nail leg 4832a " fragment The fragment 4833b of 4833a " and 4834a " and the second nail leg 4832b' " and 4834b ".In contrast nail 4830' and nail 4830 " Afterwards, reader will appreciate that, nail 4830 " fragment 4833b " and 4834b " between angle than follow closely 4830' fragment 4833b' and Angle between 4834b' becomes apparent from or bigger.In other words, distally nail 4830 " is less symmetrical than nearside nail 4830'.One In the case of a little, the histokinesis at the distal end 4813 of nail bin 4800 can be more than the histokinesis at proximal end 4816, and Correspondingly, nail orientation displacement can at the distal end 4813 of nail bin 4800 ratio it is big at proximal end 4816.Compared to warp The smaller asymmetry of 4830', distally nail 4830 are followed closely by the nearside that is shifted compared with tingle " larger asymmetry can compensate for compared with spike Displacement.This is an example and can be compensated different nails displacements using the nail of any suitable species in staple.For example, setting Wanting to be located at the nail at the proximal end that longitudinal direction is arranged can have than following closely big asymmetry at the distal end of longitudinal direction row.Also Longitudinal direction row is envisioned using more than two groups of asymmetric nails.

As described above, the histokinesis or flowing at the distal end of end effector can in all cases be more than end Histokinesis or flowing at the proximal end of actuator.Such case can be transported because of distally of the firing member in end effector Move and occur.Although firing member is configured to, as it is progressively sutured towards distally motion and cuts tissue, hit Hair component also can be advanced or promoted and organize towards distally.This promote or propulsion efficiency can since the proximal end of end effector and Can be combined as firing member is moved towards distally so that the promotion of maximum is realized at the distal end of end effector or is pushed away Enter effect.Therefore, than that described above, histokinesis and nail shifting can be compensated using the gradient for following closely asymmetry in longitudinal staple The gradient of position.

Except or replace above-mentioned, nail bin can utilize the protuberance with different height control to be organized in end effector Motion.In all cases, the protuberance disclosed herein for extending from the platform of nail bin can reduce nail bin and be performed with end Gap between the anvil block of device.Therefore, compared to the embodiment without protuberance, protuberance can be to being positioned at anvil block and nail bin Middle tissue applies bigger local pressure.In all cases, the protuberance with high height can to tissue apply compared with Big compression stress or pressure and the protuberance with lower height can apply relatively small compression stress or pressure to tissue.Along These lines, compared with relatively low protuberance, protuberance higher can provide bigger control to histokinesis.As reader can remember, hold Histokinesis at the proximal end of portion's actuator is smaller than the histokinesis at the distal end of end effector, and because This, refers again to Figure 84, and nail bin 4800 can utilize relatively low protuberance 4851' and the distally at the proximal end 4816 of warehouse 4810 Protuberance higher 4851 at end 4813 ".In the case of at least one, relatively low protuberance 4851' can be from the flat of warehouse 4810 The extended distance 4855' of platform surface 4811 and protuberance higher 4851 " can be from relatively low protuberance 4851' extended distances 4855 ".At certain In the case of a little, the protuberance extended from warehouse may include the height ladder extended between the proximal end and distal end of warehouse Degree.It is as discussed above in the case of at least one, the highest protuberance of the gradient can at the distal end of warehouse institute The minimum protuberance for stating gradient can be at the proximal end of warehouse.In other cases, the highest protuberance of the gradient can be At the proximal end of warehouse and the minimum protuberance of the gradient can be at the distal end of warehouse.

As discussed above, histokinesis can be such that nail is shifted from cartridge deployment with it.In all cases, with it is relatively low Protuberance is compared, and protuberance higher can provide bigger control to this displacement.It is and relatively low more specifically, refer again to Figure 84 Proximal projections 4851' is compared, distal projections higher 4851 " nail pit 4850 can be made to extend more so that nail 4830 " by remote Side protuberance 4851 " control ratio nail 4830' is controlled longer distance by proximal projections 4851'.Compared to nail 4830' in nail The distance that the leg of 4830' is lifted up before being ejected from chamber 4850, protuberance higher 4851 " can also increase nail 4830 " in nail 4830 " distance that leg is lifted up before being ejected from chamber 4850.This arrangement can shorten for example follows closely 4830 " in nail bin Distance exposed to larger histokinesis and/or time at 4800 distal end.
