As discussed above, tissue of the capture between the anvil block and nail bin of surgical end-effector can held during use It moves in portion's actuator or is flowed relative to end effector.As also discussed above, this movement or flowing can generally be Towards distal side, because the firing member of end effector is moved distally to fire the nail being removedly stored in nail bin and cut Enter tissue.If firing member proximally moves, the movement or flowing organized be will be substantially proximally.But it organizes Nail can be made to shift during percussion process towards distal side towards distal side flowing.This phenomenon is as shown in figure 30.Figure 30 is shown from being defined in The nail 2630 that nail cavity 2650 in warehouse 2610 ejects.Nail 2630 is shown at the position at least partly fired, wherein following closely Driver 2640 moves up the base portion 2631 of nail 2630 towards anvil block 20, and the wherein leg 2632a of nail 2630, 2632b appears from nail cavity 2650 and has contacted anvil block 20.Such as it will be appreciate that, nail cavity 2650 may include the first protruding portion 2651a and the first end wall 2652a, first protruding portion and the first end wall are configured to the first nail leg 2632a of support, and And similarly, it may include the second protruding portion 2651b and second sidewall 2652b, second protruding portion and second sidewall are constructed The second nail leg 2632b is supported at when can be ejected by driver 2640 from nail cavity 2650 following closely 2630.However, as shown in figure 30, Nail 2630 can be shifted towards distal side so that nail leg 2632a is shifted far from the first end wall 2652a and nail leg during percussion process The second protruding portion 2651b is crossed in 2632b displacement.Although nail 2630 is shifted towards distal side, the first leg 2632a has still been received In first forming cup 22a of the nail pit being defined in anvil block 20 and the second leg 2632b has still been received the of nail pit In two forming cup 22b.Although nail leg 2632a, 2632b can contact its corresponding forming cup 22a, 22b, nail 2630 towards distal side Displacement may not obtain symmetrically shaped nail, as shown in such as Figure 31.Figure 31, which is shown, to be promoted by staple drivers 2640 to height In the storehouse platform surface 2611 of warehouse 2610 position and be deformed into the nail 2630 of its complete firing configuration.

As discussed above, due to the tissue displacement being trapped in end effector, symmetrical nail can asymmetrically become Shape.In all cases, the asymmetric nail that for example can compensate for this displacement, such as Figure 24 and Figure 27 to Figure 29 institute can be used in nail bin The asymmetric nail shown.The nail leg of these asymmetric nails can be constructed in the following manner: when asymmetric nail is shifted towards distal side, they can It is displaced in the orientation that them can be made to be deformed into symmetrical or at least more symmetrical percussion configuration.Figure 84 shows nail bin 4800, should Nail bin includes: warehouse 4810, which includes being defined in multiple nail cavities 4850 therein；It is located in asymmetric in nail cavity 4850 Nail；And it is configured to eject multiple drivers 4840 of nail from nail cavity 4850.Warehouse 4810 may include distal end 4813 and proximal end 4816, wherein nail cavity 4850 can be arranged to the longitudinal row being defined in warehouse 4810.Warehouse 4810 exists By transversal at longitudinal direction nail chamber 4850 as to show one in Figure 84.In some cases, it is removedly stored in vertical Nail into nail chamber 4850 can have identical asymmetric configuration, and in other cases, as shown in Figure 84, nail can have There is different asymmetric configurations.For example, nail 4830 ' is stored in the proximal end longitudinally arranged, and follows closely 4830 " and be stored in longitudinal row Distal end in.Similarly as described above, each nail 4830 ' may include the first nail leg 4832a ' and the second nail leg 4832b ', Wherein one or both of nail leg may include several segments, such as the segment 4833b ' and 4834b ' of the second nail leg 4832b '. It is also similarly to described above, each nail 4830 " may include the first nail leg 4832a " and the second nail leg 4832b ", wherein in nail leg One of or both may include several segments, such as the segment 4833a " and 4834a " and the second nail leg of the first nail leg 4832a " The segment 4833b " and 4834b " of 4832b '.Comparison nail 4830' and nail 4830 " after, it will be appreciate that, nail 4830 " segment Angle between the segment 4833b' and 4834b' of angle between 4833b " and 4834b " than following closely 4830' becomes apparent from or bigger. In other words, distal side nail 4830 " is less symmetrical than nearside nail 4830 '.In some cases, the distal end of nail bin 4800 The tissue that tissue movement at 4813 can be greater than at proximal end 4816 is mobile, and correspondingly, the displacement in nail orientation is being followed closely Than bigger at proximal end 4816 at the distal end 4813 in storehouse 4800.Compared to the nearside nail for being subjected to shifting compared with tingle 4830 ' lesser asymmetry, the biggish asymmetry of distal side nail 4830 " can compensate for biggish nail displacement.This is one A example and different nail can be compensated using the nail of any suitable species in staple and shift.For example, it is contemplated that being located in vertical There is bigger asymmetry than the nail being located at the distal end longitudinally arranged to the nail at the proximal end of row.It is contemplated that Longitudinal row, which can be used, is more than two groups of asymmetric nails.

As described above, in all cases, the tissue at end effector distal end is mobile or flowing can be greater than end Tissue at actuator proximal end is mobile or flows.Such situation can due in end effector firing member towards distal side move It moves and occurs.Although firing member is configured to progressively suture and cut tissue when it is moved distally, percussion Component can also plough dynamic or promotion tissue towards distal side.This promotion or the dynamic effect of plough may begin at the proximal end of end effector simultaneously And it can be aggravated when firing member is moved distally so that realizing maximum promotion or plough at the distal end of end effector Dynamic effect.Therefore, in addition to described above, can be compensated in longitudinal staple using the gradient in nail asymmetry tissue it is mobile and Gradient in nail displacement.

In addition to or replace it is described above, nail bin the protruding portion with different height can be used control group be woven in end execute Movement in device.In all cases, the protruding portion disclosed herein extended from the platform of nail bin can reduce end effector Nail bin and anvil block between gap.Therefore, compared to the embodiment of not protruding portion, protruding portion can be located in anvil block with Tissue among nail bin applies bigger local pressure.In all cases, the protruding portion with high height can be applied to tissue Add biggish compressing force or pressure, and the protruding portion with shorter height can apply relatively small compressing force or pressure to tissue Power.Along these lines, shorter protruding portion is compared, higher protruding portion mobile to tissue can provide biggish control.As reader will remember It rising, the mobile tissue being smaller than at end effector distal end of the tissue at end effector proximal end is mobile, and because This, referring again to Figure 84, nail bin 4800 can at the proximal end 4816 of warehouse 4810 using shorter protruding portion 4851 ' and Higher protruding portion 4851 " is used at distal end 4813.In at least one situation, shorter protruding portion 4851 ' can be from warehouse 4810 4811 extended distance 4855 ' of platform surface, and higher protruding portion 4851 " can from shorter protruding portion 4851 ' extend away from From 4855 ".It in some cases, may include prolonging between the proximal end and distal end of warehouse from the protruding portion that warehouse extends The gradient for the height stretched.In at least one situation, as discussed above, the highest protruding portion of gradient can be located at the distal side of warehouse End, and the shorter protruding portion of gradient can be located at the proximal end of warehouse.In other cases, the highest protruding portion of gradient It can be located at the proximal end of warehouse, and the shorter protruding portion of gradient can be located at the distal end of warehouse.

As discussed above, when just following closely from cartridge deployment, tissue movement can be such that nail shifts.In all cases, it compares Shorter protruding portion, higher protruding portion can provide biggish control to such displacement.More specifically, comparing referring again to Figure 84 Short proximal projections 4851 ', higher distal projections 4851 " can make nail pit 4850 extend more, so that compared to nail 4830 ' It is controlled by proximal projections 4851 ', nail 4830 " controls longer distance by distal projections 4851 ".Compared to following closely wherein 4830 ' the distances being lifted up are followed closely in 4830 ' leg before appearing from chamber 4850, higher protruding portion 4851 " can also increase wherein 4830 " the distances being lifted up are followed closely before appearing from chamber 4850 in the leg of nail 4830 ".Such arrangement, which can be reduced, wherein follows closely 4830 " cruelly Reveal the distance and/or time mobile to the larger tissue at such as 4800 distal end of nail bin.

Surgical stapler uses in the prior art, to cut longitudinal cut in the tissue simultaneously and by rows of suture Nail is applied to the opposite sides of notch.This instrument usually includes a pair of jaw member to cooperate, if be intended to instrument For endoscope type or laparoscopic type application, then jaw member can pass through sleeve channel.The reception of one of jaw member has nail bin, The nail bin has at least two nails being spaced laterally apart.Another jaw member limits anvil block, which has and the staple pair in storehouse Quasi- nail shapes pit.Instrument includes multiple reciprocating wedges, and when present dynasty distal side drives, the multiple reciprocating wedge is worn The driver being open and engage support nail in nail bin is crossed, to realize the percussion of nail towards anvil block.

Tissue is cut off while by forming staple on the every side of notch, it is possible to reduce is bled and is simplified surgical operation.By In endoscope type and the post-operative recovery time of laparoscopic surgery be less and further advantage, therefore abdominal is compared, these Operation is more and more preferred.Endoscope type suture and cutting off apparatus, which use, often to be upward deflected when being clamped in thick tissue Elongated nip component.In thick tissue, upward deflect can be because between anvil block and storehouse for this of freedom (distal side) end of jaw Distant gap leads to the difference in height of forming nail greater than nearside gap.To ensure that more consistent nearside follows closely forming, anvil block to distal side It inwardly arches upward or is bent generally toward nail bin.This arch upward relatively is suitable for thick tissue and can make when on thin tissue relatively tight Nail formed at the distal end.To overcome this close distal side closure, increase to the clamping surface of the neighbouring storehouse distal end in storehouse If pin or bump.Closure on anvil block to pin ensures the minimum clearance at distal end.However, surgeon worries pin Or bump will lead to tissue trauma.

To cope with such challenge, various arrangements have been developed.For example, a kind of arrangement includes " E mast " cutting head or percussion Bar, " the E mast " or trigger shaft are configured to effectively be spaced apart anvil block with the elongated passageway of support nail cartridge.It is such E mast cutting head or trigger shaft are arranged in for example entitled " SURGICAL STAPLING INSTRUMENT It is disclosed in the United States Patent (USP) 6,978,921 of INCORPORATING AN E-BEAM FIRING MECHANISM ", the United States Patent (USP) Complete disclosure be hereby incorporated by reference.

For example, tissue cutting head includes the E mast that can be translated in end effector 16 as shown in Fig. 2 and Fig. 3 of this paper 50.As described above, E mast 50 may include vertical portion 52, the vertical portion can be passed through when E mast 50 is promoted towards distal side prolongs Extend through narrow longitudinal anvil block slot 58 of the tissue contacting surface 60 in anvil block 20, the narrow vertical slit 62 in nail bin 42, And the narrow longitudinal channel 64 in elongate staple channel 40.Anvil block slot 58 can be extended up in anvil block 20 and can be wrapped The end being passed through in the vertical passage 66 of lateral widening is included, the vertical passage 66 of the lateral widening is sized and configured so that it Receive the upper pin 54 being laterally extended from vertical portion 52.Similarly, passage slot 64 can extend downwardly into channel 40 and It may include the end being passed through in the vertical passage 68 of lateral widening, the size and construction of the vertical passage 68 of the lateral widening make It obtains it and receives the one or more lower legs 70 being laterally extended from vertical portion 52.E mast 50 may also include one or more Intermediate pin 72, the intermediate pin can be laterally extended from vertical portion 52 and be configured to the chassis 74 along nail bin 42 Top surface sliding.In certain embodiments, intermediate pin 72 is configured to fixed nail bin 42, or ensures nail bin 42 remain in channel 40.The size for the longitudinal percussion groove 75 being formed in the nail bin 42 of 74 top of chassis is set to allow for Intermediate pin 72 translates across nail bin 42.

Various elongated passageways arrangement includes elongated or longitudinal slit, described elongated or longitudinal slit E mast cutting head in Extend between starting position and the end position adjacent with the distal end of elongated passageway in the portions of proximal of elongated passageway.E The vertical portion of mast cutting head extends through longitudinal slit, and the lower leg part of E mast is along the bottom of elongated passageway Surface extension.Pin portions can help to effectively be spaced anvil block relative to elongated passageway, and also act as clinician Find out the convenient manner of position of the cutting head in elongated passageway.By observing the cutting when cutting head is advanced through storehouse towards distal side The position of head pin, clinician will definitely instruct position of the cutting head in storehouse.For interval anvil block and monitoring cutting head While position provides effective means, such to be arranged in elongated passageway using longitudinal slit, which can reduce channel Rigidity and channel are to torsion and the resistance extended.

For the such extension for avoiding elongated passageway, it may be necessary to eliminate elongated passageway to enhance when suturing thick tissue to torsion The resistance for turning and extending.However, such arrangement may make surgeon that can not check seam by observing the position of knife pin Conjunction have been carried out how far.Figure 32 show can be similar with various elongated passageways disclosed herein in addition to following difference it is elongated Channel 6022, the elongated passageway 6022 include such as elongated passageway 22 and 302.Elongated passageway 6022 can be by suitable polymeric material Material moulds and/or is machined and/or is formed in other ways, and including substantially solid bottom surface portion 6024. Elongated passageway 6022 is configured to support surgery nail bin (not shown) wherein.Elongated passageway 6022 may include from two to The elongated interior slit 6026 that the chimb part 6028 of interior extension limits.The chimb part 6028 to extend internally is also in chimb part Internal path 6030 is limited between 6028 and solid bottom part 6024.Although elongated interior slit 6026 extends up to elongated passageway 6022 most of length, but its bottom surface 6024 for not extending across elongated passageway 6022.The ruler of the internal path 6030 It is very little to be set to slidably receive the one or more pins for being formed in or being otherwise affixed to cutting head.

Figure 42 shows the E mast cutting head 6050 for example used in combination with elongated passageway 6022.However, will such as become aobvious And be clear to, elongated passageway 6022 can also be arranged with a variety of different cutting heads and is used in combination, a variety of different cutting head cloth It sets on the bottom of cutting head using single pin or multiple pins.Referring to fig. 42, cutting head 6050 includes laterally being prolonged with two The vertical portion 6052 that the lower leg 6070 stretched terminates.Vertical portion 6052 is configured to across elongated slot 6026, So that lower leg 6070 is received in corresponding 6028 lower section of chimb part.

Referring again to Figure 32, elongated passageway 6022 may also include the close of the bottom part 6024 that elongated passageway 6022 is arranged in Proximal channel opening 6040 in side end.Proximal channel opening 6040 can allow clinician that can be in cutting head 6050 and open At least one of the pin 6070 of observation cutting head 6050 or one or more of the other part when beginning or non-firing position.This " starting position " can also be with the cutting head when cutting head 6050 is in the locked position of coupler that will such as discuss in further detail below The location of 6050 is corresponding.Similarly, distal channel opening 6042 is equipped in the distal end of bottom part 6024, this is remote Wing passage opening can allow clinician being capable of the observation cutting when cutting head 6050 is in its " percussion completely " or " end position " At least one of first 6050 pin 6070 or one or more of the other part.This arrange provides to clinician for visiting Know that cutting head is to be in its end position in its starting position while providing elongated compared to extending longitudinally through The method of the relatively harder elongated passageway in other channels of the longitudinal slit of the bottom in channel.Proximal channel opening 6040 and distal side Access portal 6042 can be configured with light into elongated passageway 6022 conducive to such as cutting head 6050 in a manner of shown in Figure 32 Installation (passing through proximal channel opening 6040) and cutting head 6050 (are open from the removal of elongated passageway 6022 by distal channel 6042).Therefore, elongated passageway 6022 has including opening corresponding with the beginning and end of cutting head firing schedule respectively 6040,6042 closing bottom.It is this to arrange the beginning and end for allowing to see percussion and allow cutting head to such as be under The latched position that text is discussed in further detail moves downward.

Elongated passageway 6022 can effectively with cutting that is manually advancing or being promoted by motro drivien trigger system Head assembly is used together.For example, surgical instruments 10 described above includes the cutting manually advanced by actuating trigger 32 First 50.In various arrangements, cutting head 50 can be advanced to stop bits from its starting position by activating firing trigger 32 three times It sets.Thus, for example, cutting head can be moved distally starting position and stop bits by an actuating trigger 32 in elongated passageway The one third (" the first firing position ") the distance between set.Second of startup trigger can lead to the traveling of cutting head 50 and start 2/3rds (" the second firing positions ") and third time startup trigger 32 of distance between position and end position can lead to Propulsion of the cutting head 50 from the second firing position to end position.Therefore, when cutting head 6050 can be open by distal channel 6042 when seeing, clinician will be appreciated by cutting head 6050 and be fired completely.Such elongated passageway 6022 can also be with electric power type (Figure 19 to Figure 22) is used in combination surgical instruments 1010.

Figure 33 to Figure 35 shows another elongated passageway that elongated passageway 6022 is similar in addition to the difference being previously mentioned Arrangement 6122.The part those of identical as the part of elongated passageway arrangement 6022 of elongated passageway arrangement 6122 will share identical Element number.In particular, as shown in Figure 33, a series of indicator openings spaced apart are provided in bottom part 6124 6144.Indicator opening 6144 can change in quantity, size and spacing, but at least one arrangement, indicator opening 6144 have identical size and evenly-spaced in a row so that they lead in elongated interior access 6030.It such as can be at that Seen in a little figures, indicator opening 6144 is circular shape.It is same as shown in Figure 33, it can be in the proximal end of elongated passageway 6122 Light source 6160 is installed in portion projects light onto light source 6160 in internal path 6030 (with dotted line " L " in Figure 33 and Figure 34 It indicates).Light source 6160 may include for example one or more light emitting diodes (" LED ") or other light sources arrangement, it is one or Multiple light emitting diodes or other light sources arrangement can receive across conductor 6164 electric power, the conductor be connected to surgical instruments or The shank of robot system etc., elongated passageway 6122 are operatively attached to the shank.When light source 6160 is powered, light will It projects in internal path 6030.When cutting head 6050 is in starting position, cutting head 6050 can stop any light " L " to pass through Indicator opening any one of 6144 and it is visible.Therefore, when there is no light " L " to pass through indicator opening any one of 6144 It can be seen that when, clinician will be appreciated by cutting head 6050 and be in starting position.When cutting head 6050 is advanced through indicator towards distal side Be open 6144 when, light " L " will be mapped on cutting head 6050 and at least through the unobstructed indicator close to cutting head 6050 Opening 6144 is as it can be seen that as shown in figure 34.Therefore, such arrangement enable the clinician in cutting head in elongated passageway 6122 from Its starting position monitors the process of cutting head 6050 when being moved distally its end position.This elongated passageway arrangement is also than tool There is those of the most elongated slot for the bottom surface for extending fully through elongated passageway elongated passageway arrangement more firmly and more Rigidity.In one arrangement, clinician can determine the position of cutting head, because no illumination was shot through where cutting head Indicator opening.All other indicator opening by have from its irradiation across light.Therefore, in one arrangement, " black " Or not bright indicator opening is the position where cutting head.In other embodiments, light source can be omitted.Clinician can be still Position of the cutting head 6050 in elongated passageway 6122 is monitored by the position by 6144 observation pin 6070 of indicator opening It sets.
