As discussed above, being trapped in the tissue between the anvil block of surgical end-effector and nail bin can exist during use It moves in end effector or is flowed relative to end effector.Also as discussed above, this movement or flowing can be held in end The firing member of row device moves toward the far side when removedly storing the nail in nail bin to fire and cut tissue as substantially distal side 's.If firing member proximally moves, then the movement or flowing organized may be substantially nearside.Nevertheless, tissue Distal side flowing can be such that nail shifts towards distal side during percussion.This phenomenon is shown in FIG. 30.Figure 30 is shown from being defined in storehouse The nail 2630 that nail cavity 2650 in body 2610 ejects.Nail 2630 is shown at least partly firing position, in this position, nail 2630 base portion 2631 is just moved upwards by staple drivers 2640 towards anvil block 20, and in this position, follows closely 2630 leg 2632a, 2632b are ejected from nail cavity 2650 and have been contacted anvil block 20.Such as reader will appreciate that, nail cavity 2650 may include being constructed At the first protruding portion 2651a and the first end wall 2652a that can support the first nail leg 2632a and similarly it is adapted to It is enough follow closely 2630 ejected by driver 2640 from nail cavity 2650 when support the second protruding portion 2651b and the of the second nail leg 2632b Two side wall 2652b.However, as shown in figure 30, nail 2630 can shift during percussion towards distal side, so that nail leg 2632a is separate First end wall 2652a is shifted and nail leg 2632b is shifted on the second protruding portion 2651b.Although nail 2630 is shifted towards distal side, 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 It has still received in the second forming cup 22b of nail pit.Although nail leg 2632a, 2632b can contact its correspondingly configured cup 22a, 22b, but the distal side displacement of nail 2630 may not cause to be symmetrically staple shown in such as Figure 31.Figure 31 is shown to be driven by nail Device 2640 is improved to greater than the position on 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 be deformed because being trapped in the tissue displacement in end effector. In all cases, nail bin is for example followed closely using the asymmetry that can compensate for this displacement, such as shown in Figure 24 and Figure 27 to Figure 29 Asymmetry nail.These asymmetry nail nail legs can be configured so that in this way when asymmetry nail towards distal side shift when, it The orientation that them can be caused to be deformed into symmetrical or at least more symmetrical percussion configuration can be shifted into.Figure 84 is shown including warehouse 4810 nail bin 4800, the warehouse include the asymmetry for being defined in multiple nail cavities 4850 therein, being located in nail cavity 4850 It follows closely and is 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 row being defined in warehouse 4810.Warehouse 4810 exists By transversal in a manner of such in Figure 84, so that showing such longitudinal nail chamber 4850.In some cases, it removedly deposits Store up nail in longitudinal nail chamber 4850 can asymmetric configuration having the same, and in other cases, as shown in Figure 84, nail can With different asymmetric configurations.For example, nail 4830' is stored in the proximal end longitudinally arranged and follows closely 4830 " and be stored in longitudinal direction In the distal end of row.Similar to above-mentioned, each nail 4830' may include the first nail leg 4832a' and the second nail leg 4832b', Described in one or both of nail leg for example may include several segments, such as segment 4833b' of the second nail leg 4832b' 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 ", wherein institute Stating one or both of nail leg for example may include several segments, such as segment 4833a " of the first nail leg 4832a " and The segment 4833b " and 4834b " of 4834a " and the second nail leg 4832b'.After comparison nail 4830' and nail 4830 ", reader will Understand, between segment 4833b' and 4834b' of the angle between the segment 4833b " and 4834b " of nail 4830 " than following closely 4830' Angle becomes apparent from or bigger.In other words, distal side nail 4830 " is less symmetrical than nearside nail 4830'.In some cases, it follows closely Histokinesis at the distal end 4813 in storehouse 4800 can be greater than the histokinesis at proximal end 4816, and correspondingly, nail takes To displacement can at the distal end 4813 of nail bin 4800 ratio it is big at proximal end 4816.Compared to be subjected to compared with tingle shift Nearside nail 4830' smaller asymmetry, distal side nail 4830 " larger asymmetry can compensate for compared with spike shift.This is One example and different nail can be compensated using the nail of any suitable species in staple and shift.For example, it is envisioned that being located at longitudinal Nail at the proximal end of row, which can have, follows closely big asymmetry than being located at the distal end longitudinally arranged.It is contemplated that longitudinal row Using more than two groups asymmetry nails.

As described above, the histokinesis or flowing at the distal end of end effector can be greater than end in all cases Histokinesis or flowing at the proximal end of actuator.Such case can be transported because of distal side of the firing member in end effector It moves and occurs.Although firing member is configured to move toward the far side with it and progressively suture and cut tissue, hit Tissue can also be promoted or push towards distal side by sending out component.This push or propulsion efficiency can since the proximal end of end effector and It can be moved toward the far side with firing member and compound, so that realizing maximum promotion at the distal end of end effector or pushing away Into effect.Therefore, than that described above, histokinesis can be compensated using the gradient of nail asymmetry in longitudinal staple and nail moves The gradient of position.

In addition to or replace it is above-mentioned, nail bin can using have different height protruding portion be woven in end effector to control group Movement.In all cases, nail bin can be reduced from the protruding portion disclosed herein that the platform of nail bin extends and end executes Gap between the anvil block of device.Therefore, compared to the embodiment of not protruding portion, protruding portion can be to being located in anvil block and nail bin Intermediate tissue applies bigger local pressure.In all cases, with high height protruding portion can to tissue apply compared with Big compressing force or pressure and the protruding portion with lower height can apply relatively small compressing force or pressure to tissue.Along These lines, compared with lower protruding portion, higher protruding portion can provide histokinesis bigger control.If reader can remember, end Histokinesis at the proximal end of portion's actuator is smaller than the histokinesis at the distal end of end effector, and because This, referring again to Figure 84, nail bin 4800 can utilize lower protruding portion 4851' and the distal side at the proximal end 4816 of warehouse 4810 Higher protruding portion 4851 " at end 4813.In at least one situation, lower protruding portion 4851' can be from the flat of warehouse 4810 4811 extended distance 4855' of platform surface and higher protruding portion 4851 " can be from lower protruding portion 4851' extended distance 4855 ".At certain In a little situations, the protruding portion extended from warehouse may include the height ladder extended between the proximal end and distal end of warehouse Degree.In at least one situation, as discussed above, the highest protruding portion of the gradient can at the distal end of warehouse institute The minimum protruding portion for stating gradient can be at the proximal end of warehouse.In other cases, the highest protruding portion of the gradient can be At the proximal end of warehouse and the minimum protruding portion of the gradient can be at the distal end of warehouse.

As discussed above, histokinesis can make to follow closely and shift with it from cartridge deployment.In all cases, with it is lower Protruding portion is compared, and higher protruding portion can provide bigger control to this displacement.It is and lower more specifically, referring again to Figure 84 Proximal projections 4851' is compared, and higher distal projections 4851 " can be such that nail pit 4850 extends more, so that nail 4830 " is by remote The control of side protruding portion 4851 " is controlled longer distance by proximal projections 4851' than nail 4830'.It is being followed closely compared to nail 4830' The distance that the leg of 4830' is lifted up before the ejection of chamber 4850, higher protruding portion 4851 " can also increase nail 4830 " and follow closely The distance that 4830 " leg is lifted up before the ejection of chamber 4850.This arragement construction can shorten such as nail 4830 " in nail bin Distance and/or the time of larger histokinesis are exposed at 4800 distal end.

Surgical stapling device uses in the prior art, to cut longitudinal cut in the tissue simultaneously and by rows of nail It is applied to the opposite side of notch.This instrument generally includes the jaw member of a pair of of collaborative work, if be intended to the instrument For endoscope type or laparoscopic type application, then the jaw member can pass through pipe path.One of jaw member receives nail Storehouse, the nail bin have at least two staples being laterally spaced apart.Another jaw member limits anvil block, and the anvil block has and storehouse In staple alignment nail shapes pit.Instrument includes multiple reciprocating wedges, the multiple reciprocal when present dynasty distal side drives Formula wedge piece passes through the opening in nail bin and engages the driver of support nail, to realize the percussion of nail towards anvil block.

Tissue is cut off simultaneously when forming staple on the every side of notch, can reduce and bleed and simplify surgical operation.It is more and more Ground, endoscopic surgery and laparoscopic surgery are better than abdominal, because they reduce post-operative recovery time and further advantage. Endoscope type suture and cutting off apparatus use the elongated nip component often upward deflected when being clamped in thick tissue.In thickness Tissue, freedom (distal side) end of jaw this upward deflect can because the distant gap between anvil block and storehouse be greater than nearside gap And lead to the difference in height of forming nail.To ensure that nearside more evenly follows closely forming to distal side, anvil block usually inward towards nail bin flare or Bending.This flare is preferable for thick tissue and can lead to when using on thin tissue relatively tight at distal end Nail form.To overcome this close distal side closure, sells or swell to the clamping surface addition in the storehouse of the distal end in neighbouring storehouse Block.Closure on anvil block to pin ensures the minimum clearance at distal end.However, surgeon's concern causes the pin of tissue trauma Or bump.

Various arragement constructions have been developed to cope with this challenge.One arragement construction is true for example including being configured to " E mast " cutting head or trigger shaft that anvil block is spaced apart with the elongated passageway of support nail cartridge on the spot.This E mast cutting head and Trigger shaft arragement construction is disclosed in for example following patent: the entitled " surgery suturing appliance including E mast firing lock The beauty of (SURGICAL STAPLING INSTRUMENT INCORPORATING AN E-BEAM FIRING MECHANISM) " In state's patent 6,978,921, the entire disclosure of the patent is hereby incorporated by reference.

For example, tissue cutting head includes the E column that can be translated in end effector 16 as shown in Fig. 2 and Fig. 3 herein Bar 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 Extend through narrow longitudinal anvil block slot 58 of the tissue contacting surface 60 in anvil block 20, the narrow vertical slit in nail bin 42 62 and elongate staple channel 40 in narrow longitudinal channel 64.Anvil block slot 58 can extend up in anvil block 20 and It may include the end for being passed through the vertical passage 66 laterally widened, the size and construction of the vertical passage laterally widened are set The upper pin 54 extended laterally at reception from vertical portion 52.Similarly, passage slot 64 can extend downwardly into channel 40 simultaneously And may include the end being passed through in the vertical passage 68 laterally widened, the size and configuration quilt of the vertical passage laterally widened It is set to receive from foot 70 under the one or more that vertical portion 52 extends laterally.E mast 50 may also include one or more Intermediate pin 72, the intermediate pin can extend laterally from vertical portion 52 and be configured to hold in the palm along the bottom of nail bin 42 The top surface of disk 74 slides.In certain embodiments, intermediate pin 72 is configured to nail bin 42 being placed in channel 40 In or ensure that nail bin 42 remains disposed in channel 40.The longitudinal direction percussion formed in nail bin 42 above bottom tray 74 is recessed The permission intermediate pin 72 that is sized to of slot 75 translates across nail bin 42.

Various elongated passageway arragement constructions include elongated or longitudinal slit, and described elongated or longitudinal slit is cut in E mast Head and prolongs at the starting position in the portions of proximal of elongated passageway between the end position adjacent with the distal end of elongated passageway It stretches.The vertical portion of E mast cutting head extends through the lower foot portion of the longitudinal slit and E mast along elongated passageway Bottom surface operation.Foot portion can help to be spaced apart anvil block relative to elongated passageway and be also used as facing What bed doctor found out position of the cutting head in elongated passageway facilitates device.By observation when cutting head is advanced through storehouse towards distal side When cutting head foot position, the position that clinician will accurately know that cutting head is located in storehouse.When offer is for being spaced apart When anvil block and the efficient apparatus of position for monitoring cutting head, this arragement construction not in elongated passageway use can reduce it is logical The longitudinal slit of the warp resistance and resistance to scalability in road rigidity and channel.

For this extension for avoiding elongated passageway, it may be desirable to which it is resistance to when suturing thick tissue to improve to eliminate longitudinal slit Warping property and resistance to scalability.However, this arragement construction can eliminate surgeon by observing the position of knife foot to understand seam Close the ability for having proceeded to which kind of degree.Figure 32, which is shown, can be similar to disclosed herein include for example in addition to following differences The elongated passageway 6022 of the various elongated passageways of elongated passageway 22 and 302.Elongated passageway 6022 can be by suitable polymer material It is molded and/or is process and/or formed in other ways and including substantially solid bottom surface portion 6024.Carefully Long-channel 6022 is configured to be operably supported surgery nail bin (not shown) wherein.Elongated passageway 6022 may include by The elongated interior slit 6026 that two chimb parts 6028 to extend internally limit.The chimb part 6028 to extend internally further defines Elongated interior access 6030 between chimb part 6028 and solid bottom part 6024.Although elongated interior slit 6026 Extend up to most of length of elongated passageway 6022, but its bottom surface 6024 for not extending across elongated passageway 6022.It is internal Being sized to be slidably received on cutting head for access 6030 forms or is otherwise affixed to cutting head One or more foots.

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 may also be incorporated on the bottom of cutting head and be cut using the various differences of single foot or multiple foots Cut an arragement construction come using.Referring to fig. 42, cutting head 6050 includes perpendicular with the two lower foots 6070 extended laterally terminations Straight part 6052.Vertical portion 6052 is configured to across elongated slot 6026, so that lower foot 6070 receives 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 be provided to clinician and be opened when cutting head 6050 is in The foot 6070 of cutting head 6050 or the view of at least one of 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 latched position that will such as discuss in further detail below The location of 6050 is corresponding.Similarly, distal channel opening 6042 be set in the distal end of bottom part 6024 with to Clinician provide when cutting head 6050 be in its " complete fire " or " end position " foot 6070 of cutting head 6050 or The view of at least one of one or more of the other part.This arragement construction is provided to clinician for finding out cutting head It is to be in its end position in its starting position while providing compared to the bottom for extending longitudinally through elongated passageway The method of the relatively harder elongated passageway in other channels of the longitudinal slit in portion.Proximal channel opening 6040 and distal channel opening 6042 can shape in a manner of shown in Figure 32 to be conducive to such as light installation of the cutting head 6050 into elongated passageway 6022 and (pass through Proximal channel opening is 6040) and cutting head 6050 is from the removal of elongated passageway 6022 (passing through distal channel opening 6042).Therefore, Elongated passageway 6022 has the closure including opening 6040,6042 corresponding with the beginning and end of cutting head firing schedule respectively Bottom.This arragement construction allows to see the beginning and end of percussion and allows cutting head to such as will in further detail below The latched position of ground discussion moves downward.

Elongated passageway 6022 can effectively with the cutting head assembly that manually advances or use motor operated type trigger system The cutting head assembly of propulsion is used together.For example, surgical instruments 10 described above includes passing through actuating trigger 32 manually The cutting head 50 of propulsion.In various arragement constructions, cutting head 50 can be and activating firing trigger 32 since it three times Position is advanced to its end position.Thus, for example, one-shot trigger 32 can be such that cutting head transports in elongated passageway towards distal side Move the one third (" the first firing position ") of the distance between starting position and end position.Second of startup trigger can be led Cause 2/3rds (" the second firing positions ") of the distance between 50 traveling starting position of cutting head and end position and third time Startup trigger 32 can lead to propulsion of the cutting head 50 from the second firing position to end position.Therefore, when 6050 energy of cutting head When enough being seen by distal channel opening 6042, clinician will be appreciated by cutting head 6050 and be fired completely.It is this elongated logical Also in combination with operated type surgical instruments 1010, (Figure 19 to Figure 22) is used in road 6022.

Figure 33 to Figure 35 shows another elongated passageway cloth that elongated passageway 6022 is similar in addition to the difference being previously mentioned Set structure 6122.Being identical to those of elongated passageway arragement construction 6122 of the part of elongated passageway arragement construction 6022 part will Share identical element number.In particular, a series of indicators openings 6144 spaced apart are set as can be seen in Figure 33 It sets in bottom part 6124.Indicator opening 6144 can be upper different at quantity, size and interval, but at least one cloth It sets in structure, indicator opening 6144 is of the same size and is equally spaced apart by a row, so that it is passed through in elongated Portion's access 6030.As can be seen in those figures, indicator opening 6144 be circular shape.Also as can be seen in Figure 33, light Source 6160 is mountable in the proximal end of elongated passageway 6122, so that light source 6160 projects light onto internal path 6030 (being indicated by the dotted line " L " in Figure 33 and Figure 34).Light source 6160 may include for example one or more light emitting diodes (" LED ") or Other light source arragement constructions of electric power can be received by conductor 6164, the conductor is connected to surgical instruments or robot system etc. Shank, elongated passageway 6122 is operably attached to the shank.When light source 6160 is powered, light be would be projected to inside In access 6030.When cutting head 6050 is in starting position, cutting head 6050 can prevent any light " L " from passing through any indicator It is open 6144 visible.Therefore, when not having light " L " visible by any indicator opening 6144, clinician will be appreciated by cutting First 6050 are in starting position.When cutting head 6050 is advanced through indicator opening 6144 towards distal side, light " L " will be mapped to cutting As it can be seen that as shown in figure 34 on first 6050 and at least through the unobstructed indicator opening 6144 close to cutting head 6050.Cause This, this arragement construction allow the clinician to monitoring cutting head 6050 with its in elongated passageway 6122 from its start bit Set the process for moving toward the far side its end position.This elongated passageway arragement construction also extends fully through elongated lead to than having Those of most elongated slot of the bottom surface in road elongated passageway arragement construction is harder and more rigid.It is tied in an arrangement In structure, since there will be no the light for shining through the indicator opening that cutting head is located therein, clinician can determine cutting head Position.All other indicator opening will have the light for shining through it.Therefore, in an arragement construction, " black " or Non-luminous indicator opening is cutting head whereabouts.In other embodiments, light source can be omitted.Clinician still may be used Position of the cutting head 6050 in elongated passageway 6122 is monitored by the position through 6144 observation foot 6070 of indicator opening It sets.
