Figure 33 shows another anvil block cap 1170 " ', which is configured to and anvil body 1132 " ' machinery Property interlock and upper body part 1165 can be welded to.In this embodiment, along anvil covers 1170 " ' each long side 1177 " ' are arranged using " joint tongue insertion groove ".In particular, the continuously or discontinuously tab 1195 " extended laterally ' from anvil covers 1170 " ' each long side 1177 " ' is prominent.Each tab 1195 " be formed in anvil body 1132 " ' in axial slots 1197 " ' is corresponding.Anvil block cap 1170 " ' from anvil body 1132 " ' distal end in opening (not shown) slide into, by anvil Seat cap " mechanically " is attached to anvil body 1132 " '.Tab 1195 " ' and slit 1197 " ' it can determine ruler relative to each other It is very little, to establish sliding friction cooperation between them.In addition, anvil block cap 1170 " ' can be soldered to anvil body 1132 " '.Anvil Seat main body 1132 " ' can be by being made convenient for the metal of welding with anvil block cap 1170 " '.Weld seam 1178 " ' anvil block cap can be surrounded 1170 " ' entire periphery 1172 " ' extends or it can be only along the long side 1177 " of anvil block cap 1170 " ' ' positioning.Weld seam 1178 " ' can be it is continuous or its can be it is discontinuous or intermittent.Weld seam 1178 " ' be discontinuous or intermittent In those embodiments, weld seam section can be uniformly distributed along anvil covers 1170 " ' long side 1177 " ' or weld seam section closer to Long side 1177 " ' distal end then can more densely packed be spaced apart, or closer to long side 1177 " ' proximal end then can be more Densely it is spaced apart.In other arrangement, weld seam section can anvil block cap 1170 " ' long side 1177 " ' central area in More densely packed it is spaced apart.

The anvil block embodiment with anvil block cap as described herein can provide several.For example, advantage can be with It is easier anvil block and firing member assembling process.That is, firing member can be worn when anvil block is attached to elongated passageway The opening crossed in anvil body is installed.Another advantage is, upper cover can improve anvil block rigidity and its to clamping tissue The resistance for the above-mentioned bending force that Shi Keneng is met with.By resisting such bending, it can reduce firing member 1660 and normally meet with The frictional force arrived.And hence it is also possible to reduce firing member from its initial position driving in surgery nail bin to final position The amount of required percussion force.

As described above, anvil body 1132 contacts to be cut and suture tissue, the group as anvil block 1130 starts to pivot It knits between the lower surface for being located in elongate anvil main body 1132 and the platform of surgery nail bin 1110.As anvil body 1132 is pressed It is reduced to tissue, anvil block 1130 may meet with sizable resistance.In order to continue closing course, when distal closure tube section 1430 is convex When wheel contact anvil block installation section 1150, it is necessary to overcome these resistances.These resistances can be usually applied on vertical direction V Distal closure tube segment 1430, it is envisaged that if excessive, these resistances may make distal closure tube section 1430 in vertical direction Upper expansion or elongation (the distance ID in Figure 31 may increase).If distal closure tube 1430 extends in the vertical direction, far Side closure pipeline section 1430 possibly can not effectively closed anvil 1130 and maintain in a fully closed position anvil block 1130.If gone out Existing such case, then firing member 1660 may meet with significant higher resistance, this will need distal side higher percussion force tomorrow Promote firing member.

Figure 34 and Figure 35 shows the enclosed member of the movable jaw for closed action to be applied to surgical instruments A kind of form.In the arrangement of illustration, enclosed member includes the distal closure tube segment for example with closure main part 1470 1430.As described above, a kind of form of interchangeable surgical tool component 1000 is configured to convenient for surgical end-effector 1100 carry out selective joint motions.For the ease of such joint motions, distal closure tube segment 1430 utilizes upper 1434 He of tang Lower tang 1436 and top double pivot links 1220 and lower double pivot link 1222 are moveably coupled to nearside and close Close pipeline section 1410.Referring to Figure 10.In one arrangement, distal closure tube segment 1430 can be processed or otherwise by pole material It is formed, which is made of for example suitable metal material.In the arrangement of illustration, closure body 1470 has outer surface 1431 and inner surface 1433, which limits upper wall portion 1440 with upper wall tranverse sectional thickness UWT and with lower wall thickness Spend the lower wall portion 1442 of LWT.Upper wall portion 1440 is located in above axis axis SA, and lower wall portion 1442 is located in axis axis Below line SA.The distal end 1441 of upper wall portion 1440 has the interior cam surface being formed thereon with cam angle degree Θ 1444.Equally in the embodiment of illustration, UWT > LWT, when this has even wall thickness than distal closure tube segment for providing The obtainable longer interior cam surface 1444 of interior cam surface.Long interior cam surface can be conducive to closing force The cam face being transmitted on anvil block installation section 1150.As it can be seen that being located in upper wall portion 1440 in same such as Figure 34 and Figure 35 Transition side wall 1446,1448 on every side of axis axis SA between lower wall portion 1442 includes general planar, vertical The inner side wall surfaces 1451,1453 of extension, which can be roughly parallel to each other.Transition side wall 1446, 1448 respectively have from upper wall thickness transitions to the wall thickness of lower wall thickness.

In the arrangement of illustration, distal closure tube segment 1430 further includes positive jaw or anvil block opening features structure 1462, It is corresponding with each of side wall 1446 and 1448 and from wherein protruding inwardly from.As in Figure 34 and Figure 35 as it can be seen that anvil block be open Feature structure 1462, which is formed in, to be mounted laterally in main body 1460, which is set to can be received in pair In the chamber 1447,1449 that should be shaped, which is processed or adjacent to the distal end 1438 of distal closure tube segment 1430 with its other party Formula is formed in transition side wall 1446,1448.Positive anvil block opening features structure 1462 extend inwardly through transition side wall 1446, Corresponding opening 1450,1452 in 1448.In the arrangement of illustration, main body 1460 is mounted laterally with weld seam 1454 and is welded to distal side It is closed pipeline section 1430.As the supplement to welding or as the substitution to welding, machine can be passed through by being mounted laterally main body 1460 Tool/frictional fit, joint tongue insertion groove arrangement, adhesive etc. are held in place.

Figure 36 to Figure 41, which is shown, has been moved to anvil block 1130 from fully closed position using distal closure tube segment 1430 One example of full open position.Figure 36 and Figure 39 shows the position of distal closure tube segment 1430, more specifically, shows When distal closure tube segment 1430 in the fully closed position when, the position of a positive anvil block opening features structure 1462.In example In the example shown, anvil block opening slope 1162 is formed in anvil block attachment flange 1151 on the downside of each.When anvil block 1130 When being in fully closed position shown in Figure 36 with distal closure tube segment 1430, in positive anvil block opening features structure 1462 Each is both positioned in chamber 1164, and the base portion which establishes on anvil block opening slope 1162 and elongated passageway 1102 divides it Between.When at that position, positive anvil block opening features structure 1462 does not contact anvil block installation section 1150 or at least not to it Apply any significant opening action or power.Figure 37 and Figure 40 is shown on proximal direction PD at the beginning of distal closure tube segment 1430 The position of anvil block 1130 and distal closure tube segment 1430 when beginning to apply opening action.As shown in Figure 37, positive jaw opening is special Levying structure 1462, initially contact anvil block is open slope 1164 so that anvil block 1130 starts to be pivoted to open position.In the arrangement of illustration In, each of positive anvil block opening features structure 1462 has slope or circular distal end 1463, in order to more preferable Ground and corresponding anvil block are open 1162 cam contact of slope.In Figure 38 and Figure 41, distal closure tube segment 1430 has retracted to it Fully retracted position, this make positive anvil block opening features structure 1462 be driven to anvil block opening slope 1162 distal end portion Portion, so that anvil block 1130 is pivoted to fully open position wherein as shown in the figure.Other embodiments can not use just To jaw opening features structure, but when distal closure tube segment has retracted to its recent side initial position, spring can be relied on Or anvil block is biased into open position by other biass arrangement.

Figure 42 and Figure 43 shows another closure of the movable jaw for closed action to be applied to surgical instruments Component.In this example, enclosed member includes distal closure tube segment 1430', can be similar to distal closure tube segment 1430, but Without positive anvil block opening features structure.Distal closure tube segment 1430' has closure main body 1470', which has Limit the outer surface 1440' and inner surface 1433' of upper wall portion 1440' and lower wall portion 1442'.As described above, it may be desirable to Using as far as possible such as interior cam surface 1444' big interior cam surface, so as to make with it is convex on anvil block installation section 1150 The cam contact of wheel surface maximizes, thus effectively will be in closed force transfer to the cam face.Therefore, distal closure tube segment Most thick wall thickness UWT, and the low portion of distal closure tube segment 1430' can be set in the upper wall portion 1440' of 1430' It can have most thin wall thickness LWT.For reference purposes, along extend through distal closure tube segment 1430' central axis or The collective reference line of point C measures UWT and LWT.Therefore, UWT and LWT relatively diametrically in the case where, UWT > LWT.This wall Thickness arrangement advantageously forms longer interior cam surface 1444'.

As seen in Figure 43, distal closure tube segment 1430' has outer surface 1431', which has circular cross section Shape.Distal closure tube segment 1430' can be process by solid bar.In the example of illustration, the first central axis is come from A_{It is interior}Inside radius R₁Inner surface 1433' is extended to, and comes from the second central axis A_OutsideOuter radius R₂Extend to outer surface 1431'.In the example of illustration, axis A_{It is interior}With distance OR off-axis A_Outside, and R₂>R₁。

Figure 44 shows another enclosed member of the movable jaw for closed action to be applied to surgical instruments.? In the example, enclosed member includes the distal closure tube segment 1430 " with closure main body 1470 ".Main body 1470 " is closed with outer Surface 1431' and inner surface 1433 " limit upper wall portion 1440 " with upper wall thickness UWT, with lower wall thickness LWT's Lower wall portion 1442 " and the two side walls part 1435' respectively with sidewall thickness SWT.In the example of illustration, UWT > LWT.In addition, UWT > LWT.Therefore, SWT > UWT > LWT.In the arrangement of illustration, sidewall sections 1435' side wall having the same Thickness SWT.In other arrangements, sidewall sections 1435' can have different thickness.As shown in Figure 44, each sidewall portion Divide the inner surface portion 1437' extended vertically inside 1435' restriction.In the embodiment of illustration, the interior table that extends vertically Face part is roughly parallel to each other.This thicker upright side walls part 1435' can contribute to prevent or at least minimize remote Side is closed the vertical elongation of pipeline section 1430 " in use.

Depicted in figure 45 in example, R is measured according to common central point or central axis C₁And R₂, and R₁> R₂.The distal closure tube segment 1430 " extended between upper part 1431 " and 1433 " ' closure main part 1470 " ' side Each of wall part 1435 " all has the sidewall thickness SWT for the UWT being substantially equal at the point along horizontal reference line HR. Horizontal reference line HR can be surveyed perpendicular to the vertical reference line VR for extending through central axis C along the vertical reference line VR Measure and compare UWT and LWT.Therefore, SWT=UWT.In other examples, when along horizontal reference line HR measurement, SWT can be omited Less than UWT.SWT can continue to reduce, until sidewall sections 1435' transition is the low portion with constant lower wall thickness LWT 1433'.Therefore, when according to perpendicular to horizontal reference axis HR and being parallel to the vertical axis of reference of correspondence of vertical axis of reference VR When VR' is measured, inner sidewall 1437 " is with angle A₂Extend.

Figure 46 shows another enclosed member of the movable jaw for closed action to be applied to surgical instruments.? In the example, enclosed member includes the distal closure tube segment 1430 " with closure main body 1470 ", which has circle Outer surface 1431 " and extend through rectangle inside access 1439 therein.Outer surface 1431 " be positioned to geometric center point or Central axis C distance R.It is surveyed when along the vertical axis of reference VR for extending through central point or central axis C as shown in the figure When amount, upper wall thickness UWT is equal to lower wall thickness LWT.When edge extends through central point or central axis C and perpendicular to vertical ginseng When examining the horizontal reference axis HR measurement of axis VR, the thickness SWT of sidewall sections 1437 " is greater than upper wall thickness UWT and lower wall thickness Spend LWT.Therefore, SWT is greater than UWT and LWT.In other words, it is located in distal closure tube segment 1430 " above horizontal reference line HR Part be the mirror image that the part below horizontal reference line HR is located in distal closure tube segment 1430 ".In this example, side 1437 " is thicker than upper wall portion and lower wall portion, and can tend to prevent or minimize distal closure tube segment in vertical direction The trend of upper elongation.Interior cam surface can be formed in the distal end of upper wall portion 1440 ".

In the arrangement of illustration, by towards distal side promote distal closure tube segment 1430 come make anvil block 1130 open position with It is moved between closed position.As shown in Figure 41, when anvil block 1130 is in a fully open position, anvil block is attached flange 1151 Distal end 1163 can extend above the platform surface 1116 of nail bin 1110.When by being pushed away on distal direction DD towards distal side When starting closing course into distal closure tube segment, the distal end 1163 of anvil block attachment flange 1151 extends past nail bin 1110 Platform surface 1116, to prevent from penetrating into tissue therebetween (this may interfere with closing course).Referring to fig. 40.Once distal closure tube segment Anvil block 1130 is moved to fully closed position by 1430, the distal end portion for being mounted laterally main body on distal closure tube segment 1430 Portion 1461 is further used as tissue stop to prevent tissue from penetrating into therebetween.Referring to fig. 41.

Figure 47 depicts a part of surgical end-effector 110', the surgical end-effector can be similar to Fig. 1 and The surgical end-effector 110 of the interchangeable surgical tool component 100 of Fig. 2.In the example shown in Figure 47, anvil block 114 is wrapped Include elongated body portion 190 and anvil block installation section 192.Anvil block installation section 192 includes that two anvil block installations spaced apart are convex Edge 194 is proximally protruded from elongated body portion 190.Each anvil block mounting flange 194 has outwardly extending ear on it Axis 196.Trunnion 196 is respectively movably received in the correspondence kidney shape slit or elongate arcuate trunnion provided in elongated passageway 112 In slit 197.When anvil block 114 is in " fully opening " position, trunnion 196 is usually located at elongate arcuate gudgeon slit 197 In bottom part 198.It can be by promoting distal closure tube segment 142 towards distal side on distal direction DD, so that distal closure tube The end 148 of section 142 is mounted on the cam face 193 formed on the anvil block installation section 192 of anvil block 114, to make anvil block 114 It is moved to closed position.When the cam face 193 on anvil block installation section 192 promotes distal closure tube segment 142 towards distal side When distal end 148, distal closure tube segment 142 make the main part 190 of anvil block 114 relative to surgery nail bin 116 axially It pivots and mobile.When distal closure tube segment 142 reaches the terminal of its closing stroke, the distal end of distal closure tube segment 142 The precipitous anvil block protrusion 191 of 148 adjoining/contacts, and for positioning anvil block 114, so that the forming in the downside of main part 190 Pit (not shown) is properly aligned with the nail in storehouse.Anvil block protrusion 191 is limited to the cam face on anvil block installation section 192 Between 193 and elongate anvil main part 190.In other words, in this arrangement, cam face 193 does not extend to anvil body 190 outmost surface 195.After distal closure tube 142 arrived the fully extended position, anvil block 114 is further applied Any closed action/power can lead to anvil block and/or closed system parts damages.As shown in Figure 47, in this arrangement, it closes Resultant force F_HIt is parallel to axis axis SA.Pass through the axis or plane T at the center of trunnion 196_AWith closing force vector F_HThe distance between It is expressed as distance X_R.Distance X_RMultiplied by closing force F_HIndicate the closure torque C for being applied to anvil block 114_M。

Figure 48 and Figure 49 shows the anvil block 1130 of the surgical end-effector 1100 for interchangeable tools component 1000 Closing force configuration.As described above, anvil trunion 1158 is pivotally mounted in the hole 1154 in elongated passageway 1102.With it is above-mentioned Anvil block 114 is different, and anvil block 1130 does not axially move.On the contrary, anvil block 1130 is confined to pivot only around anvil block axis AA.When In horizontal closed power F_H1Under inside when promoting distal closure tube segment 1430 on distal direction DD, on distal closure tube segment 1430 The interaction between cam face 1152 on cam face 1444 and anvil block installation section 1150 is so that distal closure tube segment The vertical closure force component V of 1430 experience_F.The resultant force vector F undergone by the cam face 1152 on anvil block installation section 1150_N" just Meet at " or perpendicular to interior cam surface 1444.Angle Θ in Figure 48 and Figure 49 indicates cam face 1152 and inner cam The angle of surface 1440 with respect to the horizontal plane.By resultant force vector F_NWith the axis at the center that extends through anvil trunion 1158 or Plane T_AThe distance between be expressed as moment arm M_A.Moment arm distance M_AMultiplied by resultant force vector F_NExpression is applied to anvil block 1130 Closure torque C_M1.Therefore, in horizontal closed power F_H=F_H1Application in, be applied to anvil block 1130 practical closure torque capacity will Greater than the closure torque capacity for being applied to anvil block 114, because of M_A>X_R, and the closure torque for being thus applied to anvil block 1130 will be greater than applying It is added to the closure torque of anvil block 114.Figure 49 also shows the resistance as caused by organizing during closing course.F_TIt indicates to work as tissue quilt The power generated when being clamped between anvil block and nail bin by tissue.Be applied to anvil block 1130 is somebody's turn to do " reversed " torque M_TEqual to power of organization T_FWith the axis or plane T at the center for extending through anvil trunion 1158_AThe distance between X_TMultiplied by power of organization T_F.Therefore, in order to Realize the anvil block closure of desired amount, C_M1Have to be larger than M_T。

Back to example discribed in Figure 47, it can be seen that trigger shaft 170 is attached to firing member 174, the percussion structure Part is located in elongated passageway 112 when in starting or non-firing position, and more particularly, is fully located in distal side and is closed The distal side for closing pipeline section 142, the position that the top section 175 in wherein firing member 174 is contacted with a part of anvil block 114 Place.Since when anvil block 114 is moved to closed position, firing member 174, which is positioned in its top section 175, can contact anvil At the position of seat, anvil block 114 is moved to by the closing force that this arrangement may make needs bigger is totally or fully closed position It sets.In addition, when starting trigger system, it may be necessary to bigger percussion force come overcome the top section 175 of firing member 174 with Frictional interference between anvil block 114.On the contrary, as shown in Figure 48, in end effector 1100, firing member 1660 " is parked " In the firing member parking area 1154 in distal closure tube segment 1430.When firing member 1660 is located in distal closure tube segment When in the firing member parking area 1154 in 1430, significant frictional force can not be generated with anvil block.Therefore, by the way that structure will be fired Part 1660 is parked in one of the advantages of may be implemented in distal closure tube segment 1430 completely can be, and reduces and is closed into anvil block The amount of closing force needed for fully closed position, and/or reduce firing member from the start bit in end effector Set the amount of percussion force needed for being advanced to final position.In other words, firing member 1660 is parked, so that firing member 1660 is complete Interior cam surface 1444 close to the distal end of distal closure tube segment 1430 and thereon entirely, and it is in initial position, Wherein any CONTACT WITH FRICTION between firing member and anvil block is eliminated or reduced, finally may need to generate it is lower closure and Percussion force carrys out operation end actuator.

As described above, the overbending of anvil block may undesirably to need bigger hit during closure and percussion process It has an effect.It is therefore generally desirable to which more rigid anvil block is arranged.Back to Figure 20 and Figure 21, can be retouched by anvil block 1130 and wherein Another advantage that the elongated passageway 1102 drawn provides is, the anvil block installation section 1150 of anvil block 1130 is usually more steady and therefore It is more more rigid than other anvil blocks and elongated passageway arrangement.Figure 50 shows more rigid gusset 199 in anvil block mounting flange Use between 194 and elongate anvil main part 190.It can also be in the anvil block master of anvil block attachment flange 1151 and anvil block 1130 It is arranged between body 1132 using similar gusset, to further enhance anvil block rigidity.

Another asymmetric nature of forming pit arrangement 11200 is related to the touch-down zone of each pit and going out for each pit The size of mouth region.For example, nearside pit includes touch-down zone more smaller than the touch-down zone of distal side pit and outlet area and outlet area.This Outside, the center " C " of the arrangement is not corresponding with the geometric center of crown.Adjustment forms certain features of pit arrangement with preferably suitable The tissue flowing being contemplated that, this finally can differently influence nearside and distal side nail leg, for example, can lead to asymmetry but may be most Good forming pit arrangement.

It may be advantageous for being intended to be formed the difference of forming case depth between two pits in the pit arrangement individually followed closely 's.Turning now to Figure 126 to Figure 129, shows two different suturing assemblies and arrange 11300 and 11300'.Arrangement 11300 it One (Figure 126) includes forming the pit with identical forming surface or trench, depth.Another arrangement 11300'(Figure 128) packet It includes to form the pit with differing formed case depth.Arrangement 11300,11300' are not clamped to be basically parallel to nail in anvil block It is shown in the case where the top surface or platform in storehouse.

Suturing assembly 11300 shown in Figure 126 includes: the first jaw 11310 comprising nail bin 11311；Second jaw 11320 comprising anvil block 11321；And nail 11301, it is removedly stored in storehouse 11311, is configured to pass through Sliding part 11312 is projected from storehouse 11311.Sliding part 11312 includes cam or pusher surface 11313, is configured to contact stud 11301 driving surface 11303, and nail 11301 is pushed towards the formation pit 11323 of anvil block 11321, to be formed from each nail The nail leg 11304 (near leg) and 11305 (far legs) that 11301 nail foundation 11302 extends.As described above, the arrangement 11300 forming pit 11323 includes identical forming case depth.The depth is plane anvil face 11322 and pit 11323 The distance between trench or paddy.When anvil block is at an angle of θ relative to storehouse platform 11314, using arrangement 11300 anvil block 11321 at When staple 11301, far leg 11305 will shape (Figure 127) with the forming height bigger than near leg 11304.This can also be retouched State for far leg 11305 it is not fully formed because anvil block 11321 is not clamped to so that plane anvil face 11322 is parallel to storehouse The fact that the position of platform 11314.

Other than the second jaw 11320, the suturing assembly 11300' described in Figure 128 includes and suturing assembly 11300 Identical all elements.Suturing assembly 11300' includes that the second jaw 11320', the second jaw 11320' includes anvil block 11321', Anvil block 11321' includes plane anvil face 11322' and multiple forming pits 11323A, 11323B for being limited in anvil block 11321'. As described above, forming pit 11323A, 11323B of arrangement 11300' includes different forming case depth.It is adapted to Enough formed nearside nail leg (such as nearside nail leg 11304) nearside pit 11323A include than distal side pit 11323B deeper at Shape case depth.It is configured to form distal side nail leg, the distal side pit 11323B of such as distal side nail leg 11305 includes than close The shallow forming case depth of the forming case depth of side pit 11323A, to consider potential angled jaw 11320'.When Anvil block is at an angle of θ relative to nail bin platform 11314, when using the anvil block 11321' forming nail 11301 for arranging 11300', near leg 11304 and far leg 11305 can form identical or essentially identical forming height (Figure 130).

Although anvil block is intended to be clamped to the position for the platform for making anvil face be arranged essentially parallel to storehouse, this is not always hair It is raw.For example, thicker organizing segments may be final due to unexpected organizational behavior and/or the property of surgical stapling process (this, which is likely to occur in the tissue being sutured and is finally clamped in end again, holds in the distal end section of end effector With for subsequent percussion, the percussion is than the group at the distal end for the next segment organization to be sutured in the proximal section of row device When knitting thinner and more compact).Therefore, anvil block possibly can not be clamped into substantially parallel configuration relative to storehouse.Therefore, nail can To be formed such as the nail 11301 in Figure 127, the leg 11305 and a leg 11304 formed completely formed with a part. Instead of design anvil block to ensure clamping Shi Yucang parallel alignment, a possibility that a solution may include non-parallel alignment And forming pit arrangement is designed, or forming pit pair as described above.In addition, if in the arrangement 11300' described in Figure 128 Shown anvil block is clamped at least substantially parallel to platform 11314, then the far leg followed closely can cross forming.In some cases, Crossing forming nail may be more advantageous than in lower section or partly forming (Figure 127) nail.There is provided trench depth difference between pit pair can To prevent the modification between the near leg and far leg of non-magnetic shim.

Turning now to Figure 134, table 12000 is shown, determines the feature of various forming pit arrangements.Table identification is used for The feature of forming pit arrangement 10100 and forming pit arrangement 10200.The table is also identified to be tested in finite element analysis environment Other forming pits arrangement feature, the finite element analysis environment can be similar in many aspects forming pit arrangement 10100, 10200.Forming pit arrange A1, A2 be similar to forming pit arrangement 10100, and forming pit arrangement B1, B2 be similar at Shape pit arrangement 10200.Table 12000 also identifies the feature of forming pit arrangement 12100.

Figure 135 is seen also, according at least one embodiment, feature 12001,12003,12005,12007 and 12009 is joined Carry out reference according to some and another forming pit arrangement in the forming pit arrangement identified in table 12000.From Figure 135 Top-to-bottom shows forming pit arrangement 10100, forming pit arrangement 12100, forming pit arrangement 10200 and forming The viewgraph of cross-section of pit arrangement 10400.Feature 12001 indicates that the longitudinal direction of each forming pit enters radius.12003 table of feature Show longitudinal exit radius of each forming pit.The distance between the trench of the expression forming pit pair of feature 12005.In other words It says, feature 12005 indicates the distance between the deepest point of pit in each forming pit arrangement.Feature 12007 indicates each The ridge of forming pit arrangement or the width of bridge.Feature 12009 indicates the ridge of each forming pit arrangement or the depth of bridge.

Figure 136 depict three forming pits arrangement 10100,10200,10400 and follow closely accordingly 10100', 10200', 10400' uses 10100,10200,10400 forming of forming pit arrangement respectively.Pit arrangement 10200 needs minimum Power follows closely 10200' to be formed completely.In other words, maximum, force needed for arranging 10200 forming nail 10200' with forming pit is less than The maximum, force needed for forming pit arrangement other nails of 10100,10400 forming 10100', 10400'.This can be advantageous, Because overall percussion force of following closely is made to minimize the stress and strain minimum that can make on the other component in surgical stapling component.Most A possibility that smallization mechanical stress and strain can reduce element premature failure.Necessary percussion force is reduced to also contribute to passing through requirement So strong small parts are not needed to reduce the size of shaft diameter.For example, being hit when attempting to minimize the size of shaft diameter The buckling for sending out component is generally acknowledged problem.

Figure 137 is the table 12200 of the supplementary features of determining above-mentioned various forming pit arrangements.The identification of column 12201 has been used for It is formed with the various maximum, forces of the nail of differing formed pit arrangement entirely.The mark of column 12203 with different forming pit arrange come The various maximum, forces of hypervelocity driving nail.

Figure 138 is depicted in B shaped configuration 12300 and is driven structure using the hypervelocity of 10100 forming of forming pit arrangement Nail 12301 in type 12300'.Nail 12301 includes base portion 12302 and a pair of of nail leg 12303 from the extension of base portion 12302. Each nail leg 12303 includes nail tip 12304, is configured to the contact forming when following closely 12301 and driving towards the anvil block of surgical instruments Pit.Nail 12301 includes that various bending regions or region 12305,12306 can when arranging forming by certain forming pits Bend to predictable crooked outline.Forming pit arrangement 10100 makes bending region 12305,12306 bend to discrete wheel It is wide.For example, including box like structure without the structure that is continuously formed in the nail 12301 for being fully formed configuration.It is bent region 12305,12306 include sharp bending part.Therefore, there are significant gaps between the bending part 12306 of leg 12303 Distance 12307.In addition, the clearance distance 12308 between the tip 12304 of leg 12303 is significant.It is fastened in various tissues In scene, these gaps 12307,12308 between bending part 12606 and nail tip 12304 can be less effective ground seal tissue.

Power F needed for arranging 10100 forming nails 12301 with forming pit is shown in the curve graph 12310 of Figure 138. Power distribution curve includes specific region and peak 12302,12303,12304,12305,12306.Initial peak 12302 indicates right with it The tip for the forming pit answered is hit or nib contacts.Once nail tip depression stricken is simultaneously sticked in the outlet area of pit, leg 12303 just will be bent and start to be bent at bending region 12306.The bending in these bending regions 12306 corresponds to curve graph 12310 part 12313.Once bending region 12306, which wholly or largely shapes and is bent region 12306, contacts pit Inlet region shape surface, then leg 12303 proceeded to for the second buckling stage.Once it is recessed to be bent the contact forming of region 12306 Buckling is entered B and forms shape bending region 12305 by hole, leg 12303.The second buckling stage generates the second power peak 12314.

When nail 12301 forms over its B shaped configuration 12300, nail is in hypervelocity driving configuration 12300'.Such case Generation there are many reason.One reason may be that nail 12301 is thus lifted to above the platform of nail bin to pop up completely from nail bin Nail 12301.Hypervelocity about nail 12301 drives configuration 12300', and gap 12308 is significant in the distance between nail tip 12304 Increase.It is added in addition, the leg 12303 of nail 12301 has begun to be formed between base portion 12302 and bending region 12305 Hypervelocity driving bending region.When the region bends, forming nail height can be reduced, this may also lead to the efficiency drop of seal tissue It is low.In addition, the bending " B " of nail leg 12303 can occur when the region bends.The bending " B " includes width, which is increasing Added-time can make nail 12301 be less effective ground seal tissue.Referring to curve graph 12310, the second power peak 12316 indicates hypervelocity driving Power needed for nail 12301.The power is noticeably greater than the power needed for B forming nail 12301 at peak 12314.

Figure 139 is depicted in B shaped configuration 12320 and is driven structure using the hypervelocity of 10200 forming of forming pit arrangement Nail 12321 in type 12320'.Nail 12321 includes base portion 12322 and a pair of of nail leg 12323 from the extension of base portion 12322. Each nail leg 12323 includes nail tip 12324, is configured to when nail 12321 is driven towards the anvil block of surgical instruments Contact corresponding forming pit.Nail 12321 includes various bending regions or region 12325,12326, when by certain forming pits It is flexible at predictable crooked outline when arrangement forming.Forming pit arrangement 10200 makes to be bent region 12325,12326 Bend to bending region 12305, the 12306 more continuous profiles of the nail 12301 than using forming pit arrangement 10100 to shape. In other words, the nail 12321 of B shaped configuration includes practical " B " more closer than the discrete curved configuration of nail 12301 being fully formed Follow closely the profile of configuration.Bending region 12325,12326 includes the bending curvature radius bigger than bending region 12305,12306. Therefore, the clearance distance 12327 between the bending part 12326 of leg 12323 is less than clearance distance 12307.In addition, leg Clearance distance 12328 between 12323 tip 12324 is less than clearance distance 12308.It is curved in various tissues fastening scene Small gap 12327,12328 between bent portions 12626 and nail tip 12324 can help to more effectively seal than nail 12301 Tissue.The tissue capture ability of nail 12321 can be increased by minimizing these clearance distances.

Power F needed for arranging 10200 forming nails 12321 with forming pit is shown in the curve graph 12330 of Figure 139. Power distribution curve includes specific region 12333,12335 and peak 12332,12334,12336.Initial peak 12332 indicates right with it The tip for the forming pit answered is hit or nib contacts.Once nail tip depression stricken is simultaneously sticked in the outlet area of pit, leg 12323 just will be bent and start to be bent at bending region 12326.The bending in these bending regions 12326 corresponds to curve graph 12330 part 12333.Once bending region 12326 wholly or largely shapes and is bent region 12326 in pit Inlet region, which shapes, to be contacted and is slided in surface, then leg 12323 proceeded to for the second buckling stage.Once being bent region 12326 Forming pit is contacted, buckling is entered B and forms shape bending region 12325 by leg 12323.The second buckling stage generates the second power Peak 12334.Compared with nail 12301, using forming pit arrangement 12321 forming nail 10200 need lesser power come completely at Shape.

In the case where the forming of nail 12321 is more than its B shaped configuration 12320, it is referred to alternatively as hypervelocity driving configuration 12320'. Hypervelocity relative to nail 12321 drives configuration 12320', and clearance distance 12328 has increased in the distance between nail tip 12304 Add, still, the gap is unlike in the clearance distance in its driving configuration 12300' that exceeds the speed limit between the point 12304 of nail 12301 Significantly.The clearance distance 12327 being bent between region 12326 is reduced.In addition, the leg 12323 of nail 12321 has begun Additional hypervelocity driving bending region is formed between base portion 12322 and bending region 12325.But with follow closely 12301 phases Than the bending " B " of nail leg 12323 is less than bending " B " of the nail leg 12303 in its driving configuration 12300' that exceeds the speed limit.Referring to Figure 139 In curve graph 12330, power needed for another power peak 12336 indicates hypervelocity driving nail 12321.Power 12336 is similar to B forming nail Power 12334 needed for 12301.Therefore, in the case that exceed the speed limit driving percussion nail 12321 power for the rest part of instrument It is important not as good as the power of percussion nail 12301 when exceeding the speed limit driving.

Forming pit arrangement 10100 and nail 12301 are shown at tip impact phase in Figure 140 and Figure 141 12400, first bending stage 12400', second bending stage 12400 " and B or be fully formed the stage 12400 " '.At tip During impact phase 12400, the leg for following closely 12301 is configured to buckling into the first bending stage 12400'.In buckling Later, leg curvature forms the first bending region.Leg is configured to make contact to the entrance of shape pit in the first bending region Second time of buckling when the second bending stage 12400 ".After the second time of buckling, leg is formed by bending the second bending again Region.Then, nail 12301 complete forming, and it is desirable that realize be fully formed the stage 12400 " '.As in Figure 141 as it can be seen that complete Full shaping stage 12400 " ' shows the nail 12301 with discrete bending leg.

Forming pit arrangement 10200 and nail 12321 are shown at tip impact phase in Figure 142 and Figure 143 12500, first bending stage 12500', second bending the stage 12500 " and be fully formed the stage 12500 " '.It is hit at tip During stage 12500, the leg for following closely 12501 is configured to buckling into the first bending stage 12500'.After buckling, Leg curvature forms the first bending region.First bending region of nail 12321 includes bigger than the first bending region of nail 12301 Radius of curvature.Leg is configured to when the first bending region makes contact to shape pit and entered for the second bending stage 12500 " Second time of buckling.After the second time of buckling, leg is formed by bending the second bending region again.The second of nail 12321 is curved Bent region includes the radius of curvature bigger than the second bending region of nail 12301.Since the bending region of nail 12321 includes than nail The bigger radius of curvature in 12301 bending region, the leg for following closely 12321 includes the nail leg more continuously shaped.Then, it follows closely 12321 complete forming, and it is desirable that realize be fully formed the stage 12500 " '.As in Figure 143 as it can be seen that being fully formed the stage 12500 " ' show the nail 12321 with the nail leg than following closely 12301 more progressive formings.Therefore, nail 12321 is than following closely 12301 more Similar real " B " structure.

Compared with nail 12301 and its corresponding forming pit arrangement 10100, nail 12321 is formed to have than nail 12301 more Small tissue pathway or surface area.During forming nail, big tissue pathway surface area may cause excessive tissue and draw It stretches and/or tears.Since the profile of forming nail 12321 has more continuous curvature, compared to leg 12303 and tip 12304, Leg 12323 closer to tip 12324 path formation and follow.

Figure 144 and Figure 145 depicts the nail 12301,12321 formed from its tip impact phase to part shaping stage. The part shaping stage is referred to as tip adhesion phase.As in Figure 144 as it can be seen that leg 12303 is configured to buckling Region 12306 is bent to be formed.When forming leg 12303 using forming pit arrangement 10100, leg load experienced Including first degree of eccentricity.As in Figure 145 as it can be seen that leg 12323 is configured to buckling to form bending region 12326.When When forming leg 12323 using forming pit arrangement 10200, leg load experienced includes second degree of eccentricity.Due at Shape pit arranges that 10100,10200 pit shape has differences, and second degree of eccentricity is greater than first degree of eccentricity.This relationship makes Inflection point is different.For example, leg 12303 is at bending region 12306 from benchmark D deflection distance D1.Leg 12323 is being bent From benchmark D deflection distance D2 at region 12326.Distance D2 is less than distance D1.Reducing amount of deflection or reducing bending region 12326 makes It obtains leg 12323 with bigger radius of curvature buckling and to shape, to form the nail leg of more progressive forming.
