Nail cavity 1116 is angularly orientated relative to axis axis SA.More specifically, nail cavity 1116 relative to axis axis SA with Oblique angle orientation, and herringbone pattern is formed in platform surface 1115.This document describes the various another of the nail cavity in staple cartridge body The pattern of choosing.

The arrangement of nail in staple line and/or the variation of geometry can influence the flexibility and sealing characteristics of staple line.For example, by The staple line that linear nail is constituted can provide limited amount flexible or stretching, because staple line can bend or stretch between linear nail.Cause This, the finite part (for example, part between nail) of staple line is flexible.It can also by the staple line that the nail being angularly orientated is constituted It bends or stretches between nail.However, the nail being angularly oriented can also rotate, this provides additional stretching journey in staple line Degree.For example, the staple line being made of the nail being angularly orientated is stretchable more than 60%.In some instances, for example, by being at an angle of The staple line stretchable at least 25% or at least 50% that the nail of orientation is constituted.For example, the arrangement of nail includes the relative orientation and nail of nail Between spacing.For example, the geometry of nail includes the size and shape of nail.Arrangement and/or geometry based on nail, staple line Flexibility and sealing characteristics can change at longitudinal direction and/or lateral position.In some instances, it is desirable to along one of staple line or Change the flexibility and/or sealing characteristics of staple line at multiple positions.Such as, it may be desirable to make staple line or part thereof of flexible maximum Change.In addition to this or alternatively, it may be desirable to make staple line or part thereof of flexible minimum.It may also desire to make staple line or one portion The sealing characteristics divided maximize.In addition to this or alternatively, it may be desirable to minimize staple line or part thereof of sealing characteristics.

The arrangement of nail cavity corresponds to the arrangement of the nail in staple line caused by nail bin in nail bin.For example, the nail cavity in nail bin Spacing and relative orientation correspond to the spacing and relative orientation of the nail in the staple line generated by nail bin.In various examples, nail Storehouse may include the arrangement of nail cavity, be selected and/or designed to the flexibility and/or sealing characteristics of optimization gained staple line.For example, outer Section doctor can be specific to select to have based on the characteristic of tissue to be treated during pending surgical operation and/or surgical operation The nail bin of the nail cavity of arrangement.

In some instances, it may be desirable to generate the staple line with different nail patterns.Staple line may include for its first part First nail pattern and for its second part second follow closely pattern.First pattern and the second pattern can longitudinal biasing.For example, the One pattern can be positioned at the proximal end or distal end of staple line.In other instances, first pattern and the second pattern can Strategic Lateral Offset, and in other instances, first pattern and the second pattern can Strategic Lateral Offset and longitudinal biasing.Staple line may include to Few two different nail patterns.

In some instances, most of nail in staple line can form master pattern, and other nails in staple line can form one A or multiple secondary patterns.Master pattern may span across the pith of staple line and may include longitudinal duplicate sub-pattern.In certain realities In example, secondary pattern or irregular shape can deviate master pattern.Secondary pattern can be the one or more for example along the length of staple line Exception at position.Different pattern in staple line is configured to generate different characteristics in pre-position.For example, main Pattern can be highly flexible or the pattern of elasticity, allow the extensive stretching of the tissue of suture, and secondary pattern can be less soft Property or it is less elastic.Such as, it may be desirable to most of staple line highly flexible, and one or more finite part flexibilities are lower.? In other examples, secondary pattern is more flexible than master pattern.In some instances, the shorter part due to secondary pattern along staple line is prolonged It stretches, because the flexibility of this pattern can not influence or be not significantly affected by the overall flex of entire staple line.

Referring now to Figure 25 and Figure 26, staple cartridge body 4700 is shown.Staple cartridge body 4700 is similar to staple cartridge body in many aspects 3000.For example, staple cartridge body 4700 includes the first pattern 4720 of the nail cavity 4710 being angularly oriented, with herringbone pattern cloth It sets.Slit 4704 extends through the platform 4702 of staple cartridge body 4700 along the longitudinal axis L A of warehouse 4700.Staple cartridge body 4700 also wraps Include the nearside nail cavity 4710a-4710f being arranged in nearside pattern 4722.Nearside pattern 4722 include internal nail cavity 4710c and 4710d is oriented to be parallel to longitudinal axis L A.Nearside pattern 4722 further includes the external nail cavity 4710a being angularly oriented And 4710f, and the intermediate cavity 4710b and 4710e that are angularly oriented.External nail cavity 4710a and 4710f and intermediate nail cavity 4710b and 4710e is orientated relative to longitudinal axis L A with inclination angle.The external nail cavity 4710a and 4710f being angularly oriented also phase The cavity axis of nail cavity 4710 in first pattern 4720 is orientated with inclination angle.The angle of external nail cavity 4710a and 4710f is small The angle of nail cavity 4710 in the first pattern 4720.In other words, external nail cavity 4710a and 4710f is than the first pattern Nail cavity 4710 in 4720 is orientated closer to the angle parallel with longitudinal axis L A.In the illustration being described, nearside pattern 4722 There is smaller flexibility than the first pattern 4720.

Intermediate nail cavity 4710b and 4710e is oriented to the certain nail cavities 4710 being parallel in the first pattern 4020.For example, Intermediate nail cavity 4710b and 4710e is oriented to the nail cavity 4710 in the interior row being parallel in the first pattern 4720.Although nearside figure Certain nail cavities in case 4722 do not bias angularly with the nail cavity in the first pattern 4020, but when considered as a whole, The duplicate subregion in longitudinal direction that nearside pattern 4722 is different from the first pattern 4020 and is different from the first pattern 4020.

Nearside pattern 4722 includes three nail cavities being positioned on each side of slit 4704.In other instances, It can be arranged in the nearside pattern 4722 on the one or both sides of slit 4704 and be less than three nail cavities or more than three nail cavity.Nearside Pattern 4722 does not include longitudinal duplicate sub-pattern.In other instances, nearside pattern 4722 can be longitudinal duplicate.Separately Outside, nearside pattern 4722 is symmetrical relative to longitudinal axis L A.In other instances, nearside pattern 4722 can be relative to longitudinal axis LA is asymmetric.

Driver 4760 is positioned in the nail cavity 4710 in warehouse 4700.As described herein, the nail of the first pattern 4720 Driver 4760 in chamber 4710 is three drivers.Nearside driver 4760a, 4760b, 4760c, 4760d, 4710e and 4710f It is respectively positioned in nearside the nail cavity 4710a, 4710b, 4710c, 4710d, 4710e and 4710f of nearside pattern 4722.Nearside Driver 4760a-4760f is single driver.In some instances, the nearside driver in inner cavity 4710c and 4710d 4760c and 4760d can be single driver respectively, and nearside driver 4760a and 4760b can be the driver of connection, and Nearside driver 4760e and 4760f can be the driver of connection.In other instances, nearside driver 4760a, 4760b and 4760c may include the driver of the first connection, and distal side driver 4760d, 4760e and 4760f may include the second connection Driver.

It will be appreciate that the various patterns of nail cavity described herein can be combined and/or be exchanged.In some instances, nail cavity One or more irregular patterns can be limited at the proximal end and/or distal end of staple cartridge body.In addition to this or optionally One or more irregular patterns or secondary pattern can be clipped in or be inserted into master pattern by ground.

The angle orientation of nail in staple line can influence to suture tissue along the flexibility or compliance of staple line.For example, when nail is opposite When longitudinal axis and/or cutting line are orientated with inclination angle, the flexibility of staple line can increase.This angle orientation may be in response to edge and cut The power such as tension and/or torsion of secant and/or neighbouring cutting line and flexible or scalability is provided within certain limits.More Body, the flexibility of staple line allows stretching, bending, folding and/or the distortion of suture tissue.In general, the angle when nail is orientated phase For staple line and/or cutting line longitudinal axis close to 45 degree or 135 degree when, suture the flexible of tissue and increase.For example, by angulation The staple line that the nail of degree orientation is constituted can be considered as submissive or elastic staple line.

In some instances, the flexibility of staple line can be laterally varied relative to cutting line.For example, in the first part of staple line One or more nail can be orientated relative to cutting line with first angle, and one or more nails in the second part of staple line can It is orientated at different angles relative to cutting line.The first part of staple line can have the first flexibility, and the second part of staple line There can be different flexibilities.In some instances, first part can be with second part Strategic Lateral Offset.For example, first of staple line It point may include a part of the first staple or first row, and the second part of staple line may include the one of the second staple or second row Part.In the illustration being described, the flexibility along the staple line of the first staple may differ from the flexibility of the staple line along the second staple.

Referring now to Figure 27, a part of staple cartridge body 3200 is shown.Staple cartridge body 3200 includes that platform 3202 and longitudinal direction are narrow Slot 3204.Axis LA extends longitudinal slit 3204 along longitudinal direction.Nail cavity 3210 is limited in staple cartridge body 3200, and each nail cavity 3210 limit opening 3212 in platform 3202.Nail 3242 is positioned in each nail cavity 3210.Nail 3242 in many aspects may be used Similar to 3142 (Figure 11) of 3042 (Figure 10) of nail or nail.In some instances, the leg of each nail 3242 can be biased against nail cavity 3210 inner wall.It will be appreciate that the arrangement of the nail 3242 in nail cavity 3210 corresponds to when nail 3242 is hit from staple cartridge body 3200 Arrangement of the nail 3242 in staple line when sending out and entering tissue.More specifically, the base portion of each nail 3242 in obtained staple line It is conllinear with cavity axis CA or be substantially collinear.

Nail cavity opening 3212 is arranged to three rows 3214a, 3214b and 3214c on the first side of longitudinal slit 3204. Inner opening 3212a limits the periphery of the inner cavity 3210a in interior row 3214a, and middle opening 3212b is limited in intermediate row 3214b The periphery of intermediate cavity 3210b, and outward opening 3212c limits the periphery of the exocoel 3210c in outlet 3214c.Inside nail 3242a It is positioned in the 3210a of inner cavity, centre nail 3242b is positioned in intermediate cavity 3210b, and external nail 3242c is positioned in In exocoel 3210c.Although not being shown in FIG. 27, at least one example, the nail cavity on opposite sides 3210 of slit 3204 Form the mirror reflection of the nail cavity 3210 on the first side of longitudinal slit 3204.Therefore, the nail 3242 in obtained staple line Arrangement it is symmetrical relative to cutting line.In other instances, staple line can be relative to cutting line asymmetry.

Each nail cavity opening 3212 has first end or proximal end 3216 and the second end or distal end 3218.Chamber Axis CA extends between the proximal end 3216 and distal end 3218 of each opening 3212.Nail cavity in each corresponding row is opened Mouth 3212 is parallel.For example, inner cavity 3210a is orientated relative to longitudinal axis L A with angle A.In other words, inner opening 3212a Cavity axis (for example, CA_A1And CA_A2) be orientated relative to longitudinal axis L A with angle A.Intermediate cavity 3210b is relative to longitudinal axis LA is orientated with angle B.In other words, the cavity axis of middle opening 3212b is (for example, CA_B1And CA_B2) relative to longitudinal axis L A It is orientated with angle B.Exocoel 3210c is relative to longitudinal axis L A with angle C orientation.In other words, it is limited by outward opening 3212 Cavity axis is (for example, CA_C1And CA_C2) be orientated relative to longitudinal axis L A with angle C.

Angle A, B and C are different.Therefore, inner opening 3212a is obliquely orientated relative to outward opening 3212c.Because outer The cavity axis CA of opening 3212c is (for example, axis CA_C1And CA_C2) cavity axis of inner opening 3212a is not parallel to (for example, axis CA_A1And CA_A2), the opening 3212 in staple cartridge body 3200 forms modification or inclined herringbone pattern.Middle opening 3212b's Cavity axis CA_B1And CA_B2It can be orientated normal to or be substantially perpendicular to inner opening 3212a or outward opening 3212c.For example, angle B can be the supplementary angle of angle A or angle C.In other instances, angle B may not be the supplementary angle of angle A or angle C.

Since angle A, B and C are different, the width W of the staple in staple line_A、W_B、W_CIt can be different.For example, internal nail 3242a shape At with width W_AStaple, centre nail 3242b formed have width W_BStaple, and external nail 3242c is formed has width W_CStaple.Width W_AAnd W_CIt is different, because angle A is different from angle C.In some instances, width W_BDifferent from width W_AAnd W_C.In other instances, width W_BIt can match width W_AOr W_CIn one.For example, if angle B is the supplementary angle of angle A, Then width W_BWith width W_AMatching.Similarly, if angle B is the supplementary angle of angle C, width W_BWith width W_CMatching.

Further, since angle A, B and C difference, follow closely the longitudinal length L of 3242a, 3242b and 3242c_A、L_BAnd L_CRespectively not Together.For example, internal nail 3242a has longitudinal length L_A, centre nail 3242b is with longitudinal length L_B, and external nail 3242c tool There is longitudinal length L_C.Longitudinal length L_AAnd L_CIt is different, because angle A is different from angle C.Because of longitudinal length L_AAnd L_CNo Together, so internal nail 3242a is relative to outside nail 3242c is at least partly longitudinally staggered or biasing.In other words, each inside At least one end for following closely 3242a is not aligned with the corresponding end of external nail 3242b.Because end is misaligned, relative to The longitudinal overlap of centre nail 3242b and/or gap are different between inside nail 3242a and external nail 3242c.In certain examples In, longitudinal length L_BDifferent from length L_AAnd L_C.In other instances, longitudinal length L_BIt can be with longitudinal length L_AOr L_CIn one Matching.For example, if angle B is the supplementary angle of angle A, longitudinal length L_BWith longitudinal length L_AMatching.Similarly, if angle B It is the supplementary angle of angle C, then longitudinal length L_BWith longitudinal length L_CMatching.

The length of base portion can also influence width W_A、W_BAnd W_CAnd longitudinal length L_A、L_BAnd L_C.In staple cartridge body 3200, Inside nail 3242a, intermediate nail 3242b and external nail 3242c have the base portion of equal length.For example, identical nail can be positioned In each nail cavity 3210.In other instances, as further described herein, for example, having different geometries and/or ruler The nail of the base portion of very little such as different length can be positioned in certain nail cavities in warehouse.

Referring still to Figure 27, the angle orientation of nail cavity 3210a, 3210b and 3210c and corresponding width W_A、W_BAnd W_CWith And longitudinal length L_A、L_BAnd L_CThe laterally and longitudinally lap in staple line can be influenced respectively.Longitudinally and laterally weighing between nail 3242 The folded spacing for additionally depending on nail cavity 3210.In general, the greater overlap between adjacent nail corresponds to more roundabout fluid path, this It can correspond to bigger tissue encapsulation characteristic.Bigger overlapping can also reduce the flexibility of staple line, because tissue can be in overlapping region In by more multiple constraint.In addition, bigger overlapping can correspond to the smaller spacing between nail.In some instances, it may be desirable to change Become lateral and/or longitudinal overlap the degree in staple line.As overlapping changes, the flexibility and sealing characteristics of staple line be can also change.

For example, overlapping described herein or overlapping degree can refer to plus lap or under lap.When nail and/or staple limit weight bearing When folded, nail and/or staple can be spaced, so that they are not overlapped and limit gap between them.In other instances, nail or Staple can be aligned, so that overlapping is equal to the diameter of nail.

Reader will be further understood that the overlapping degree relative to nail or staple in nail bin corresponds to relative in nail bin The overlapping degree of nail cavity or nail cavity row.For example, lateral and/or longitudinal overlap the relative different between nail or staple corresponds to nail Lateral and/or longitudinal overlap the relative different of nail cavity or nail cavity row in storehouse.In some instances, at least part of nail leg It is positioned against the inner wall of the nail cavity at the proximal end and distal end of nail cavity and/or is biased to wherein.In the example In, the distance that the outer edge relative to nail measures is equal to the distance of the inward flange measurement relative to corresponding nail cavity.In other examples In, the difference between these distances can be the smallest or inessential.

In some instances, overlapping degree can be made to minimize, such as when the end alignment of nail.When the end alignment of nail When, it is overlapped equal with the diameter of nail or is essentially equal.For example, if nail is made of the wire rod that diameter is about 0.0079 inch, Then overlapping can be about 0.0079 inch.In other instances, overlapping is smaller than the diameter of nail.For example, overlapping is smaller than about 0.0079 inch.In other instances, overlapping degree can be non-overlap or under lap, that is, space between the end of nail or Gap.In other instances, the overlapping of minimum can be equal to or less than the one third for following closely length.For example, overlapping is smaller than nail The 33% of length.In other instances, overlapping is smaller than the 25% of nail length or less than the 10% of nail length.In other examples In, for example, overlapping can be 33% or more of nail length.

In some instances, staple line may include the first overlapping degree and intermediate nail between internal staple and intermediate staple The second overlapping degree between row and external staple.Second overlapping degree can be Chong Die with first on lateral and/or longitudinal direction Degree is different.Therefore, the interior section of staple line may include the flexibility different from the exterior section of staple line.In addition, interior section Tissue encapsulation characteristic may differ from the tissue encapsulation characteristic of exterior section.

Referring again to Figure 27, angle A is less than angle C.Therefore, width W_ALess than width W_C, and length L_AGreater than length L_C.For example, angle A can be 35 degree to 40 degree, and angle C can be such as 43 degree to 47 degree.In other instances, angle A be smaller than 35 degree or greater than 40 degree and/or angle C be smaller than 43 degree or be greater than 47 degree.Difference between angle A and angle C can Between three degree to 12 degree.For example, difference can be about octave.In other instances, the difference between angle A and angle C It is smaller than three degree or greater than 12 degree.

Referring still to Figure 27, the nail 3242 in each corresponding row is aligned.More specifically, the proximal end of internal nail 3242a Longitudinally aligned, the distal end of inside nail 3242a is longitudinally aligned, and the proximal end of centre nail 3242b is longitudinally aligned, centre nail The distal end of 3242b is longitudinally aligned, and the proximal end of outside nail 3242c is longitudinally aligned, and the distal end portion of external nail 3242c Portion is longitudinally aligned.The nail 3242 of alignment in each row 3214a of nail cavity 3310,3214b and 3214c is configured to following closely The nail 3242 of multiple rows of alignment is formed in line.Due to the angle orientation of nail 3242 and the spacing between them, 3242 side of staple is to again It is folded.Inside nail 3242a passes through lateral overlap Y_A/B3242b lateral overlap is followed closely with centre, and external nail 3242c is by laterally weighing Folded Y_B/C3242b lateral overlap is followed closely with centre.Lateral overlap Y between inside nail 3242a and intermediate nail 3242b_A/BGreater than outside Follow closely the lateral overlap Y between 3242c and intermediate nail 3242b_B/C.In the illustration being described, intermediate nail is navigated to compared to inside nail, Outside nail is positioned closer to intermediate nail.In other instances, lateral overlap Y_A/BIt may be less than or equal to lateral overlap Y_B/C。

Centre nail 3242b is longitudinally staggered relative to inside nail 3242a and external nail 3242c.Specifically, each intermediate nail 3242b is longitudinal between adjacent inside nail 3242a equidistantly to be positioned and follows closely in adjacent outside longitudinal equidistant between 3242c Ground positioning.Due to the angle orientation of nail 3242 and the spacing between them, 3242 not longitudinal overlaps are followed closely.Inside nail 3242a is in Between follow closely the interval 3242b axial clearance X_A/B, and the external nail 3242c and intermediate nail interval 3242b axial clearance X_B/C.Inside nail Axial clearance X between 3242a and intermediate nail 3242b_A/BLess than the axial clearance between external nail 3242c and intermediate nail 3242b X_B/C.In other instances, axial clearance X_A/BAxial clearance X can be greater than or equal to_B/C.In some instances, intermediate nail 3242b It can be longitudinally be overlapped with inside nail 3242a and/or external nail 3242c.

The lateral overlap and axial clearance generated by the arrangement of the nail cavity in Figure 27 can be enough sufficiently to stop across staple line Fluid passage is with seal tissue.In various examples, lateral and/or longitudinal overlap and/or gap are configured to select Optimize to property the sealing characteristics of staple line.In addition to this or alternatively, lateral and/or longitudinal overlap and/or gap can be configured to The flexibility of staple line can selectively be optimized.In addition, overlapping can be made to minimize.In some instances, lateral overlap is smaller than nail The one third of length, and may approximately equal at least one example the diameter of nail.

Referring now to Figure 28, a part of staple cartridge body 3300 is shown.Staple cartridge body 3300 includes that platform 3302 and longitudinal direction are narrow Slot 3304.Axis LA extends longitudinal slit 3304 along longitudinal direction.Nail cavity 3310 is limited in staple cartridge body 3300, and each nail cavity 3310 include the opening 3312 in platform 3302.Nail 3342 is positioned in each nail cavity 3310.Nail 3342 in many aspects may be used Similar to 3142 (Figure 11) of 3042 (Figure 10) of nail or nail.In some instances, the leg of each nail 3342 can be biased against nail cavity 3310 inner wall.It will be appreciate that the arrangement of the nail 3342 in nail cavity 3310 corresponds to when nail 3342 is hit from staple cartridge body 3300 Arrangement of the nail 3342 in staple line when sending out and entering tissue.More specifically, the base portion of each nail 3342 in obtained staple line It is conllinear with cavity axis CA or be substantially collinear.

Nail cavity opening 3312 is arranged to three rows 3314a, 3314b and 3314c on the first side of longitudinal slit 3304. Inner opening 3312a limits the periphery of the inner cavity 3310a in interior row 3314a, and middle opening 3312b is limited in intermediate row 3314b The periphery of intermediate cavity 3310b, and outward opening 3312c limits the periphery of the exocoel 3310c in outlet 3314c.Inside nail 3342a It is positioned in the 3310a of inner cavity, centre nail 3342b is positioned in intermediate cavity 3310b, and external nail 3342c is positioned in In exocoel 3310c.Although not being shown in FIG. 28, at least one example, the nail cavity on opposite sides 3310 of slit 3304 Form the mirror reflection of the nail cavity 3310 on the first side of longitudinal slit 3304.Therefore, the nail 3342 in obtained staple line Arrangement it is symmetrical relative to cutting line.In other instances, staple line can be relative to cutting line asymmetry.

Each nail cavity opening 3312 has first end or proximal end 3316 and the second end or distal end 3318.Chamber Axis CA extends between the proximal end 3316 and distal end 3318 of each opening 3312.Nail cavity in each corresponding row is opened Mouth 3312 is parallel.For example, inner cavity 3310a is orientated relative to longitudinal axis L A with angle A.In other words, inner opening 3312a Cavity axis (for example, CA_A) be orientated relative to longitudinal axis L A with angle A.Intermediate cavity 3310b is relative to longitudinal axis L A with angle Spend B orientation.In other words, the cavity axis of middle opening 3312b is (for example, CA_B) be orientated relative to longitudinal axis L A with angle B. Exocoel 3310c is relative to longitudinal axis L A with angle C orientation.In other words, limited by outward opening 3312c cavity axis (for example, CA_C) be orientated relative to longitudinal axis L A with angle C.

In staple cartridge body 3300, angle A is equal to angle C, and angle B is angle A and the supplementary angle of C.Therefore, inner opening 3312a is parallel to outward opening 3312c, and middle opening 3312b is respectively perpendicular to inner opening 3312a and outward opening 3312c.Nail Nail cavity opening 3312 in warehouse 3300 forms herringbone pattern.In addition, referring still to Figure 28, each row 3314a, 3314b, Nail 3342 in 3314c has the base portion BL of equal length.The width of staple is equal, and follows closely 3342 longitudinal length also phase Deng.

Longitudinal overlap X referring still to Figure 28, between inside nail 3342a and intermediate nail 3342b_A/B3342c is followed closely equal to outside Longitudinal overlap X between intermediate nail 3342b_B/C.In addition, the lateral overlap Y between internal nail 3342a and intermediate nail 3342b_A/B Equal to the lateral overlap Y between external nail 3342c and intermediate nail 3342b_B/C.In the illustration being described, intermediate nail 3342b is equidistant Ground is close to internal nail 3342a and external nail 3342c positioning.

Referring still to Figure 28, minimize the spacing between the nail cavity 3310 in warehouse 3300.For example, nail cavity opening 3312 Proximal end 3316 and distal end 3318 be positioned adjacent to other nail cavities 3312.In some instances, adjacent nail cavity can Adjacent contact.Nail cavity 3310 by minimizing the spacing between nail cavity 3310, in the density of nail cavity 3310 and the arrangement of Figure 28 Between overlapping degree be maximized.Although overlapping degree maximizes, close due to nail cavity, lateral overlap is still small In the one third of nail length.

In other instances, the angle orientation of the nail cavity at least one nail cavity row can be with the angle of the nail cavity in other rows Orientation is different.In addition to this or alternatively, during the length of the base portion at least one nail cavity row can be arranged at least another The length of base portion is different.In addition to this or alternatively, nail cavity can not with the adjacent nail cavity in each adjacent row equidistantly staggeredly or Biasing.This variation of nail bin and nail therein can generate staple line laterally with different characteristics relative to cutting line.

In some instances, for example, the nail (nail for hair of such as repelling and attacking out of nail cavity) in the interior section of staple line can have There is the base length that the nail in the exterior section from staple line is different.For example, in the interior row of the nail cavity on each side of cutter slit Nail can have base portion longer than nail in other rows of nail cavity.Longer base portion can provide bigger sealability, because Such as nail can capture more tissues.In addition to this or alternatively, longer base portion can enhance staple line and reduce its flexibility.

Referring now to Figure 29, a part of staple cartridge body 3400 is shown.Staple cartridge body 3400 includes that platform 3402 and longitudinal direction are narrow Slot 3404.Axis LA extends longitudinal slit 3404 along longitudinal direction.Nail cavity 3410 is limited in staple cartridge body 3400, and each nail cavity 3410 limit opening 3412 in platform 3402.Nail 3442 is positioned in each nail cavity 3410.Nail 3442 in many aspects may be used Similar to 3142 (Figure 11) of 3042 (Figure 10) of nail or nail.In some instances, the leg of each nail 3442 can be biased against nail cavity 3410 inner wall.It will be appreciate that the arrangement of the nail 3442 in nail cavity 3410 corresponds to when nail 3442 is fired from warehouse 3400 And arrangement of the nail 3442 in staple line when entering tissue.More specifically, the base portion of each nail 3442 in obtained staple line with Cavity axis CA is conllinear or is substantially collinear.

Nail cavity opening 3412 is arranged to three rows 3414a, 3414b and 3414c on the first side of longitudinal slit 3404. Inner opening 3412a limits the periphery of the inner cavity 3410a in interior row 3414a, and middle opening 3412b is limited in intermediate row 3414b The periphery of intermediate cavity 3410b, and outward opening 3412c limits the periphery of the exocoel 3410c in outlet 3414c.Inside nail 3442a It is positioned in the 3410a of inner cavity, centre nail 3442b is positioned in intermediate cavity 3410b, and external nail 3442c is positioned in In exocoel 3410c.Although not being shown in FIG. 29, at least one example, the nail cavity on opposite sides 3410 of slit 3404 Form the mirror reflection of the nail cavity 3410 on the first side of longitudinal slit 3404.Therefore, the nail 3442 in obtained staple line Arrangement it is symmetrical relative to cutting line.In other instances, staple line can be relative to cutting line asymmetry.

Referring still to Figure 31, the staple line generated by staple cartridge body 3600 can laterally have different spies relative to cutting line Property.Specifically, compared to from cutting line, laterally outwardly, staple line can have bigger sealing effect adjacent to cutting line.In addition, comparing In inwardly cutting line, staple line, which is laterally away from cutting line, can have bigger flexibility.For example, because nail 3642a, 3642b and The base portion BL of 3642c_A、BL_BAnd BL_CLength be respectively facing cutting line and increase laterally inward, so the interior section of staple line can have There is the sealing effect bigger than the exterior section of staple line.In addition to this or alternatively, because following closely 3642a, 3642b and 3642c Angle is oriented away from cutting line and laterally outwardly increases, thus the exterior section of staple line can have it is bigger than the interior section of staple line It is flexible.

As described herein, nail, which is removedly positioned in nail bin and during use from nail bin, is fired.Various In example, nail can be displaced from the nail cavity in nail bin and with anvil block shaping contact.For example, percussion element can be in the firing schedule phase Between translate across nail bin, will follow closely from nail bin towards anvil block drive.In some instances, nail can be supported by staple drivers, and Percussion element can promote staple drivers so that nail is projected or removed from nail bin.

Anvil block may include staple forming surface, which has nail shapes pit defined therein.In certain realities Example in, nail shapes pit can punching press in anvil block.For example, nail shapes pit is imprintable in the flat surfaces of anvil block.Reader will Understand, certain features of nail shapes pit can be the intentional consequence of moulding process.For example, at the turning of nail formed product And/or a degree of rounding of edge can be the intentional result of moulding process.It can also be designed to more preferable for these features Nail is formed as its shaping structure by ground, including becoming deflection during deployment and/or the otherwise nail that is misaligned.

Each nail in nail bin can be aligned with the nail shapes pit of anvil block.In other words, for the nail bin of end effector In nail cavity and the arrangement of nail can correspond to or the arrangement of the nail shapes pit in the anvil block of mating end actuator.More specifically The angle orientation on ground, each nail cavity can match the angle orientation of corresponding nail shapes pit.For example, when nail cavity is with herringbone pattern When arrangement, nail shapes pit can also be arranged with herringbone pattern.

When nail drive from nail bin and when with anvil block shaping contact, nail is formed as percussion and constructs.In various examples, hit Hair construction can be B shape construction, and wherein the tip of nail leg is bent towards base portion or bizet, have symmetrical top loop to be formed With the capital B of lower loop.In other instances, percussion construction can be improved B shape, and the B shape of such as deflection constructs, At least part of middle nail leg reverses out plane with base portion or asymmetric B shape constructs, and wherein capital B is upper Portion's ring and lower loop are asymmetric.It can be captured in the nail of forming or grip tissue.

The arrangement of nail and/or nail cavity in nail bin is configured to the nail shaped in surface that complementary anvil block is followed closely in optimization The corresponding arrangement of forming pit.For example, the angle orientation and spacing of the nail in nail bin may be designed to the forming surface of optimization anvil block. In some instances, the occupied area of the nail shapes pit in anvil block can be limited by the geometry of anvil block.It is shaped in nail In the case that pit is obliquely orientated relative to longitudinal axis, the width of anvil block can limit the nail shapes pit being obliquely orientated Size and spacing.For example, the width of the intermediate row of nail shapes pit can limit the first row on the side of intermediate row (outside such as Row) with the minimum range between the second row (such as in arrange) on the other side of intermediate row.In addition, rows of nail shapes pit quilt It is limited between the inside edge (such as cutter slit) of anvil block and the outer ledge of anvil block.

In various examples, pit can be adjacent to nesting along the staple forming surface of anvil block.For example, intermediate pit can be nested in Between internal pit and external pit.The angle orientation of pit can change by row in order to its nesting.For example, nail in interior row at Shape pit can be orientated with first angle, the nail shapes pit in intermediate row can at a second angle, and the nail in outlet at Shape pit can be orientated with third angle.First angle, second angle and third angle can be different, this can promote nail forming The close arrangement of pit.

Referring again to nail bin shown in Figure 27-31, the angle changing of the nail and nail cavity in each row may be selected, with optimization Nesting of the nail shapes pit in complementary anvil block.For each nail bin shown in Figure 27-31, complementary anvil block be can be configured to There can be the corresponding arrangement of nail shapes pit.In addition, the nail shapes pit in complementary anvil block is followed closely than shown in Figure 27-31 Chamber is greatly to ensure nail leg landing or fall into nail shapes pit.For example, nail leg can be outwardly biased, such as in the case where V-arrangement is followed closely (referring to Figure 11), and the larger occupied area of nail shapes pit can capture outwardly biased nail leg during percussion.Various In example, nail shapes pit is 0.005 inch to 0.015 inch long than corresponding nail cavity and/or nail.In addition to this or optionally Ground, it is 0.005 inch to 0.015 inch wide than corresponding nail cavity that cup is received in the nail joint of each nail shapes pit.In other instances, Length and/or the difference of width are smaller than 0.005 inch or greater than 0.015 inches.

(see, for example, Figure 29-31) in the example that the size of nail changes in nail bin, the size of nail shapes pit can be Correspondingly change in complementary anvil block.The size for changing nail shapes pit can further promote its nesting.For example, in intermediate row Nail shapes pit it is shorter than the nail shapes pit in interior row or outlet in the case where, can reduce nail pit intermediate row width, This can minimize the necessary spacing between interior row and outlet.

The spacing of nail shapes pit is also configured to optimize its nesting.For example, the pit being arranged in interior row can It is longitudinally staggered relative to the pit being arranged in outlet.In addition, the pit in interior row can be partly longitudinal with the pit in outlet Ground overlapping.Pit in intermediate row can be longitudinally staggered relative to the pit in the pit and outlet in interior row.For example, in intermediate row Pit can be with the equidistantly longitudinal biasing of the pit in the pit and interior row in outlet.

Referring now to Figure 80, anvil block 3700 is shown.Anvil block 3700 can be complementary with nail bin 3500 (Figure 30).For example, anvil block The arrangement of nail shapes pit 3706 in 3700 can correspond to the arrangement of nail 3542 and nail cavity 3510 (Figure 30) in nail bin 3500. Anvil block 3700 includes staple forming surface 3702 and longitudinal slit 3704.Longitudinal slit 3704 is prolonged along the longitudinal axis L A of anvil block 3700 It stretches.In some instances, longitudinal direction can be translated across during at least part of firing schedule by firing element and/or cutting element Slit 3704.Nail shapes pit 3706 is limited in staple forming surface 3702.Staple forming surface 3702 further includes around pit The 3706 non-shaped parts 3708 extended.Non-shaped part 3708 extends entirely around each pit 3706 in Figure 80.Change sentence It talks about, non-shaped part 3708 surrounds nail shapes pit 3706.In other instances, two or more adjacent pits 3706 At least part can abut contact, so that non-shaped part 3708 is not positioned between the two.

The forming ratio of staple forming surface 3702 can be optimized.By Optimize the forming scheme ratio, more nails are formable and/or are configured to Their desired constructions.In some instances, the surface region of the non-shaped part 3708 of anvil block 3700 can be shaped relative to nail Pit 3706 is minimized.In addition to this or alternatively, the occupied area of nail shapes pit 3706 is extensible or expands, with maximum Change the part for being designed to capture and formed nail of staple forming surface 3702.

Although not shown in Figure 80, at least one example, the pit on opposite sides 3706 of slit 3704 can form longitudinal narrow The mirror reflection of pit 3706 on first side of slot 3704.In other instances, the pit 3706 in staple forming surface 3702 Arrangement can be asymmetric relative to slit 3704, and in some instances, anvil block 3700 may not include longitudinal slit 3704.? In various examples, pit 3706 can be arranged on each side of slit 3704 fewer of more than three rows.

Each pit 3706 includes periphery 3716, and periphery 3716 limits the boundary of pit 3706b.Each pit 3706 also wraps Include nearside cup 3720, distal side cup 3722, and the neck portion 3724 of connection nearside cup 3720 and distal side cup 3722.When nail is driven When moving into 3702 shaping contact of staple forming surface, nearside cup 3720 is aligned with nearside nail leg, and distal side cup 3722 and distal side Nail leg alignment.The tip of nail leg is positioned and is configured to land in corresponding cup 3720,3722.In other words, closely Side cup 3720 is configured to receive nearside nail leg, and distal side cup 3722 is configured to receive distal side nail leg.Cup 3720 and 3722 are further configured to central part (such as neck portion by nail leg towards pit axis PA and pit 3806 3724) it guides or transmits (funnel), and nail leg is made to be deformed into construction formed thereby.

Geometry, spacing and/or the orientation of pit 3706 can change by row.Proximally cup 3720 prolongs pit axis PA It stretches, passes through neck portion 3724, and extend to the distal side cup 3722 of each pit 3706.Pit 3706 in every row is parallel 's.For example, inside pit 3706a is orientated relative to longitudinal axis L A with angle A.In other words, the pit of internal pit 3706a Axis is (for example, PA_A) be orientated relative to longitudinal axis L A with angle A.Intermediate pit 3706b is relative to longitudinal axis L A with angle B orientation.In other words, the pit axis of internal pit 3706b is (for example, PA_B) be orientated relative to longitudinal axis L A with angle B. External pit 3706c is relative to longitudinal axis L A with angle C orientation.In other words, the pit axis (example of internal pit 3706a Such as PA_C) be orientated relative to longitudinal axis L A with angle C.

Angle A, B and C can be different.Internal pit 3706a is obliquely orientated relative to external pit 3706c.Angle A is less than Angle C.Because the axis of external pit 3706c is (for example, axis PA_C) be not parallel to internal pit 3706a axis (for example, Axis PA_A), so the nail shapes pit 3706 in anvil block 3700 forms modification or deflection herringbone pattern.Intermediate pit The pit axis PA of 3706b_BIt is obliquely orientated relative to internal pit 3706a and outside pit 3706c.In other instances, The pit axis PA of intermediate pit 3706b_BIt can be orientated normal to or be substantially perpendicular to internal pit 3706a or external pit 3706c.For example, angle B can be angle A or the supplementary angle of C.

Internal pit 3706a has length L_A, intermediate pit 3706b is with length L_B, and outside pit 3706c has Length L_C.Length L_CLess than length L_BWith length L_A.In other words, external pit 3706c is than intermediate pit 3706b and inner-concave It is short to cheat 3706a.In some instances, length L_A、L_BAnd L_CIt can be different.In other instances, length L_A、L_BAnd L_CIt can be with It is identical.In other instances, length L_BIt is smaller than length L_AAnd/or L_BAnd/or length L_AIt is smaller than length L_AAnd/or L_C。 Selectable lengths L_A、L_BAnd L_CTo optimize the nesting of pit 3706.

The spacing of nail shapes pit 3706 is also configured to optimize its nesting.For example, internal pit 3706a can phase It is longitudinally staggered for external pit 3706c.In addition, internal pit 3706a can partly with external pit 3706c longitudinal overlap. Referring to Figure 80, the corresponding end longitudinal biasing distance X1 of the first end of internal pit 3706a and external pit 3706c_A/C.This Outside, the corresponding end longitudinal biasing distance X2 of the second end of internal pit 3706a and external pit 3706c_A/C.Distance X2_A/C Less than distance X1_A/C.In other instances, distance X2_A/CIt can be equal to or be greater than distance X1_A/C.Intermediate pit 3706b is relative to interior Portion pit 3706a and external pit 3706c are longitudinally staggered.More specifically, centre pit 3706b is in adjacent inside pit It is equidistantly longitudinally biased between 3706a and between adjacent external pit 3706c.In other instances, intermediate pit 3706b It can be biased to non-equidistant between adjacent inside pit 3706a and between adjacent external pit 3706c.

The arrangement of pit 3706 is configured to nested pit 3706, so that the cooperation of pit 3706 is in predetermined space. For example, in some instances, the width of anvil block can be minimized or otherwise limit with cooperate in surgery trochar and/ Or in narrow confined surgical areas, and the arrangement (and corresponding arrangement of nail and/or nail cavity) of nail shapes pit 3706 can Cooperation is in narrow anvil block.

Referring now to Figure 32-35C, the nail shapes pit 3806 in a part of anvil block 3800 is shown.Anvil block 3800 wraps Include staple forming surface 3802 and longitudinal slit 3804.Longitudinal slit 3804 extends along the longitudinal axis L A of anvil block 3800.Certain In example, longitudinal slit 3804 can be translated across during at least part of firing schedule by firing element and/or cutting element. Nail shapes pit 3806 is limited in staple forming surface 3802, further includes around the non-shaped part that pit 3806 extends 3808.Non-shaped part 3808 extends entirely around each pit 3806.In other words, non-shaped part 3808 is around nail forming Pit 3806.In other instances, at least part of two or more adjacent pits can abut contact, so that non-shaped portion Divide and is not positioned between the two.In some instances, non-shaped part 3808 may extend across one or more in pit 3806 It is a.

" forming ratio " (non-shaped part 3808 and shaped portion (i.e. pit 3806) of staple forming surface 3802 can be optimized Ratio).By Optimize the forming scheme ratio, more nails are formable and/or are configured to their desired constructions.In some instances, anvil The surface region of the non-shaped part 3808 of seat 3800 can be minimized relative to nail shapes pit 3806.In addition to this or optionally Ground, the occupied area of nail shapes pit 3806 is extensible or expands, and is designed to catch to maximize staple forming surface 3802 Obtain and formed the part of nail.For example, this arrangement can prevent unintentionally deformity nail, no matter for which kind of reason, nail was being fired All it can lack or fall in except their corresponding forming pits during journey.

Pit 3806 shown in Figure 32 is arranged to three rows 3814a, 3814b on the first side of longitudinal slit 3804 And 3814c.First row 3814a is interior row, and second row 3814b is intermediate row, and third row 3814c is outlet.Internal pit 3806a is located into row 3814a, and intermediate pit 3806b is positioned in intermediate row 3814b, and external pit 3806c It is positioned in outlet 3814c.Although not being shown in FIG. 32, at least one example, slit 3804 it is on opposite sides Pit 3806 can form the mirror reflection of the pit 3806 on the first side of longitudinal slit 3804.In other instances, nail forming The arrangement of pit 3806 in surface 3802 can be asymmetric relative to slit 3804, and in some instances, anvil block 3800 can It does not include longitudinal slit 3804.In various examples, pit 3806 can be arranged on each side of slit 3804 to be less than Or it is more than three rows.

Pit 3806 shown in Figure 32 is identical.The each pit 3806 being limited in staple forming surface 3802 has Identical geometry.In other instances, the geometry of pit 3806 can along anvil block 3800 length it is by row and/or longitudinal Ground variation.For example, in some instances, the depth of pit 3806 or part thereof can change along the length of anvil block 3800, to adapt to Clearance distance between anvil block and nail bin along end effector and/or the length of flow of tissue variation, as described herein.

Exemplary crater 3806b is shown in Figure 33-35C.Pit 3806b has 3810 He of first end or proximal end The second end or distal end 3812.Pit axis PA is between the proximal end 3810 and distal end 3814 of pit 3806b Extend.Referring again to Figure 32, the pit 3806 in each corresponding row is parallel.For example, the pit axis of internal pit 3806a (for example, PA_A) parallel to each other, the pit axis of intermediate pit 3806b is (for example, PA_B) parallel to each other, and external pit 3806c Pit axis (for example, PA_C) parallel to each other.Pit axis PA is obliquely orientated relative to slit 3804.In addition, intermediate pit The axis PA of 3806b_BIt is respectively oriented to the axis PA perpendicular to internal pit 3806a and external pit 3806c_AAnd PA_C.In this way, Pit 3806 is arranged to herringbone arrangement along staple forming surface 3802.

Pit 3806b includes periphery 3816, and periphery 3816 limits the boundary of pit 3806b.Pit 3806b further includes nearside Cup 3820, distal side cup 3822, and the neck portion 3824 of connection nearside cup 3820 and distal side cup 3822.When nail be driven into When 3802 shaping contact of staple forming surface, nearside cup 3820 is aligned with nearside nail leg, and distal side cup 3822 and distal side nail leg pair It is quasi-.The tip of nail leg is positioned and is configured to land in corresponding cup 3820,3822.In other words, nearside cup 3820 are configured to receive nearside nail leg, and distal side cup 3822 is configured to receive distal side nail leg.3820 Hes of cup 3822 are further configured to the central part (such as neck portion 3824) by nail leg towards pit axis PA and pit 3806 Guidance or transmission (funnel), and nail leg is made to be deformed into construction formed thereby.

Pit 3806 includes the extension touch-down zone for nail leg.The pit 3806b with reference to shown in Figure 33, pit 3806b Extend touch-down zone 3830 and distal side including nearside and extends touch-down zone 3832.Nearside extends touch-down zone 3830 and is positioned in nearside cup In 3820 portions of proximal, and distal side extends touch-down zone 3832 and is positioned in the distal part of distal side cup 3822.It extends Land area 3830 and 3832 limits substantially triangular periphery.In addition, it is whole along pit axis PA to extend touch-down zone 3830 and 3832 A point is terminated in form the turning of pit 3806b.

In other instances, for example straight and/or wave-like perimeter can be limited by extending touch-down zone 3830 and 3832, and can phase For the pit side axis PA to and/or longitudinal extend.In the example of deflection, extend and land during percussion in nail or part of it Area 3830,3832 can save or at least attempt to save the forming of the nail of deflection.

Referring primarily to Figure 34, each cup 3820,3822 of pit 3806b limits inlet slope 3840 and exit ramp 3842.Exit ramp 3842 is steeper than inlet slope 3840.When forming nail, the tip of nail leg can enter along inlet slope 3840 Corresponding cup 3820,3822 and corresponding cup 3820,3822 is left along exit ramp 3842.In inlet slope 3840 and outlet At vertex 3846 between slope 3842, the tip of nail leg is deformed towards base portion the construction of forming, such as such as B shape is presented Or the B shape of modification.Nearside cup 3820 limits the non-shaped part 3808 relative to staple forming surface 3802 at its vertex 3846 The proximal depth D of measurement₁, and distal side cup 3822 limits at its vertex 3846 relative to the non-shaped of staple forming surface 3802 The distal side depth D that part 3808 measures₂.In pit 3806b, proximal depth D₁With distal side depth D₂It is equal.In other examples In, proximal depth D₁With distal side depth D₂It can be different.

Pit 3806b limits bridgeware in the neck portion 3824 also between nearside cup 3820 and distal side cup 3822 3844.The non-shaped part 3808 of bridgeware 3844 and staple forming surface 3802 biases.More specifically, bridgeware 3844 is positioned It is recessed below non-shaped part 3808 or relative to non-shaped part 3808.In other instances, bridgeware 3844 can with it is non- Shaped portion 3808 is aligned and/or can be prominent towards the opposed jaws of end effector from non-shaped part 3808.

Referring primarily to Figure 35 A-35C, pit 3806b includes side wall 3850.Side wall 3850 is oriented to shape perpendicular to nail The non-shaped part 3808 on surface 3802.The central area 3821 of side wall 3850 towards each cup 3820,3822 broadens, and from The central area 3821 of each cup 3820,3822 narrows towards neck portion 3824.The central area 3821 widened provides and is used for Receive the widened occupied area at the tip of nail leg.Extend touch-down zone 3830,3832 and also expands the phase for receiving nail tip end Answer the occupied area of cup 3820,3822.When cup 3820,3822 narrows towards neck portion 3824, cup 3820,3822 is constructed At can towards and/or along pit axis PA transmission and/or guidance nail leg tip and enter shaping structure.With cup 3820 It broadens with 3822 and then narrows towards neck portion 3824, the periphery 3816 of pit 3806b limits profile or curved profile. In other instances, the periphery 3816 of pit 3806b can extend along the linear non-wavy profile with non-fillet.

Pit 3806b limits fillet 3852 (Figure 35 A-35C) between the side wall 3850 and bottom surface of pit 3806b.Circle Angle 3852 is configured to the guidance nail leg of the expected path in pit 3806b.For example, if nail leg is landed along fillet 3852 Or being transferred to fillet 3852, then fillet 3852 can smoothly guide nail leg towards pit axis PA.

Referring again to Figure 33, pit 3806b is symmetrical about pit axis PA.For example, the periphery 3816 of pit 3806b about Pit axis PA is symmetrical.In addition, pit 3806b is about across neck portion 3824 and perpendicular to the central axis of pit axis PA CA is symmetrical.For example, the periphery 3816 of each pit 3806 is symmetrical about central axis CA, and nearside cup 3820 has and distal side 3822 identical geometries of cup.

In other instances, nearside cup 3820 can be different from distal side cup 3822.For example, referring again to Figure 34, distal side depth D₂It is smaller than proximal depth D₁.In various examples, between the variation of the depth of nail shapes pit is suitable between anvil block and nail bin Stand-off distance from clamp tissue between the two when along end effector length variation.For example, working as anvil block close to end effector Distal end when, anvil block can be from nail bin warpage or bending.The variation of the depth of nail shapes pit 3806 is configured to Ensure to keep forming height appropriate in view of the expection of anvil block 3800 or desired warpage or bending.

In addition to this or alternatively, the variation of the depth of nail shapes pit is suitable for transporting relative to the tissue of end effector Dynamic or flowing.More specifically, the fluid in clamped tissue can when between the jaw that tissue is clamped at end effector Towards adjacent non-grip tissue flowing or movement.Tissue can be towards the longitudinal side lateral flow of anvil block 3800, towards anvil block 3800 distal end is flowed towards distal side, and/or is proximally flowed towards the proximal end of anvil block 3800.In some instances, When cut edge is advanced through tissue towards distal side, tissue can be flowed relative to anvil block 3800.In the illustration being described, tissue can Laterally, it is flowed towards distal side and/or proximally, but due to the distal movement of cut edge, so tissue is mainly flowed towards distal side. It is proximally moved in the example with incised tissue in cut edge, the movement or flowing of tissue are usually court during cutting stroke Nearside.Different depth D in pit 3806₁And D₁It is suitable for the distal side flowing of tissue, this can make the nail leg being embedded towards remote Side displacement or deflection.

In various examples, histokinesis or flowing at the distal end of end effector can be greater than end effector Histokinesis or flowing at proximal end.This example can occur due to the distal movement of firing member in end effector. Although firing member is configured to move toward the far side with it and progressively suture and cut tissue, firing member can also Tissue is promoted or pushed towards distal side.This is pushed or propulsion efficiency can be since the proximal end of end effector and can be with percussion Component moves toward the far side and compound, so that realizing maximum promotion or propulsion efficiency at the distal end of end effector.Cause This, tissue flowing can increase towards the distal end of end effector.In order to adapt to this increase of tissue flowing, pit is followed closely Geometry can along row length it is longitudinally varying.In the nearside cup of nail bin and the different examples to adapt to tissue flowing of distal side cup In, the gradient in pit asymmetry can be in row's pit using to compensate the gradient in histokinesis and nail displacement.

In some instances, different nail geometries can be used together from different pit geometries.In June, 2014 Entitled " the FASTENER CARTRIDGES INCLUDING EXTENSIONS HAVING DIFFERENT submitted for 30th It is described in the U.S. Patent Application No. 14/318,996 of CONFIGURATIONS " using different nails to adapt to execute along end The tissue of the length of device flows, which is incorporated by reference accordingly is incorporated herein.It in other instances, can be along anvil block Length use with different pit geometries identical nail.

Referring again to Figure 33, neck portion 3824 limits width W_N, and nearside cup 3820 and distal side cup 3822 limit width Spend W_C.Width W_NLess than width W_C.Therefore, the central part of pit 3806b is narrower than nearside cup 3820 and distal side cup 3822.Neck The a part of the periphery 3816 of pit 3806b at part 3824 to narrow in a part of nearside cup 3820 and distal side cup 3822 Between limit receive half island portion 3826.Due to the symmetry of pit 3806b, symmetrical half island portion 3826 that receives is positioned in pit On each side of 3806b.Half island portion 3826 is received by the periphery 3816 and tangent line axis of pit 3806b (for example, T_A、T_B1、T_B2 And T_C) define, the widest portion of the tangent line axis and nearside cup 3820 and distal side cup 3822 on the side of pit 3806 is tangent. First tangent line axis T_B1It is positioned on the first side of pit 3806b, and the second tangent line axis T_B2It is positioned in pit On the opposite side of 3806b.First tangent line axis T shown in Figure 33_B1With the second tangent line axis T_B2With pit axis PA_BIn parallel.

Referring again to Figure 32, the periphery 3816 of pit 3806 is nested along staple forming surface 3802 or interlocks.Specifically, each Pit 3806 extends in half island portion 3826 of reception of adjacent pit 3806.For example, centre pit 3806b is nested in internal pit Between 3806a and external pit 3806c.In other words, intermediate pit 3806b extends to the reception of adjacent inner pit 3806a In half island portion 3826 and extend in half island portion 3826 of reception of adjacent external pit 3806c.In addition, internal pit 3806a It is nested with centre pit 3806b with external pit 3806b.More specifically, inside pit 3806a extends to adjacent intermediate pit In half island portion 3826 of reception of 3806b, and outside pit 3806c extends to half island portion of reception of adjacent intermediate pit 3806b In 3826.

The distal side cup 3822 of intermediate pit 3806b extends across tangent line axis T_AAnd enter adjacent inner pit 3806a's Receive half island portion 3826.In addition, the nearside cup 3820 of intermediate pit 3806b extends across tangent line axis T_CAnd enter adjacent external Half island portion 3826 of reception of pit 3806c.In addition, the distal side cup 3822 of internal pit 3806a extends across tangent line axis T_B1And Into half island portion 3826 of reception of adjacent intermediate pit 3806b.In addition, the nearside cup 3820 of external pit 3806c extends across Tangent line axis T_B2And enter half island portion 3826 of reception of adjacent intermediate pit 3806b.In various examples, intermediate pit 3806b Distal side extend touch-down zone 3832 be positioned in half island portion 3826 of reception of internal pit 3806a, intermediate pit 3806b's is close Side extends touch-down zone 3830 and is positioned in half island portion 3826 of reception of external pit 3806c, and the distal side of internal pit 3806a is prolonged It stretches touch-down zone 3832 to be positioned in half island portion 3826 of reception of intermediate pit 3806b, and the nearside of external pit 3806c prolongs Touch-down zone 3830 is stretched to be positioned in half island portion 3826 of reception of intermediate pit 3806b.

The geometry of pit 3806 is convenient for nesting of the pit 3806 in staple forming surface 3802.For example, because pit 3806 include the neck portion 3824 to narrow between two widened cups 3820 and 3822, so another pit 3806 One in widened cup 3820,3822 may be positioned to the neighbouring neck portion 3824 to narrow.For example, widened cup 3820, One in 3822 can be aligned and/or be received with a part of adjacent pit 3806.In the illustration being described, can optimize by The surface region for the staple forming surface 3802 that pit 3806 covers.For example, the staple forming surface 3802 covered by pit 3806 Surface region is maximized." the forming ratio " of staple forming surface 3802 is non-shaped portion 3808 and shaped portion (that is, pit 3806) ratio.Shaping ratio is about 1.7:1.In other instances, forming is than being smaller than 1.7:1 or being greater than 1.7:1.For example, In at least one example, 50% or more of staple forming surface 3802 can be covered with nail shapes pit 3806.

The nesting for the nail shapes pit being discussed herein can refer to the nesting on adjacent pit periphery.For example, being limited in the first pit In the case where inward profile, i.e., profile extends internally towards pit axis, and adjacent second dimple can protrude towards and/or enter The region adjacent with inward profile.In addition to this or alternatively, the end of a part of second dimple such as second dimple can be with The narrowed areas of first pit is aligned.Therefore, it is aligned and compares with the wider region of the first pit with the end of second dimple, second Pit may be positioned to the pit axis closer to the first pit.

Referring now to Figure 36-39C, the nail shapes pit 3906 in a part of anvil block 3900 is shown.Anvil block 3900 wraps Include staple forming surface 3902 and longitudinal slit 3904.Longitudinal slit 3904 extends along the longitudinal axis L A of anvil block 3900.Certain In example, longitudinal slit 3904 can be translated across during at least part of firing schedule by firing element and/or cutting element. Nail shapes pit 3906 is limited in staple forming surface 3902.Staple forming surface 3902 further includes around the non-of the extension of pit 3906 Shaped portion 3908.Non-shaped part 3908 extends entirely around each pit 3906 in Figure 36.In other words, non-shaped portion 3908 are divided to surround nail shapes pit 3906.In other instances, at least part of two or more adjacent pits 3906 can Adjacent contact, so that non-shaped part 3908 is not positioned between the two.

The forming ratio of staple forming surface 3902 can be optimized.By Optimize the forming scheme ratio, more nails are formable and/or are configured to Their desired constructions.In some instances, the surface region of the non-shaped part 3908 of anvil block 3900 can be shaped relative to nail Pit 3906 is minimized.In addition to this or alternatively, the occupied area of nail shapes pit 3906 is extensible or expands, with maximum Change the part for being designed to capture and formed nail of staple forming surface 3902.

Pit 3906 shown in Figure 36 is arranged to three row 3914a on the first side of longitudinal slit 3904, 3914b, 3914c.First row 3914a is interior row, and second row 3914b is intermediate row, and third row 3914c is outlet.It is internal Pit 3906a is located into row 3914a, and intermediate pit 3906b is positioned in intermediate row 3914b, and external pit 3906c is positioned in outlet 3914c.Similar to anvil block 3800, staple forming surface 3902 cloth of the pit 3906 along anvil block 3900 It is set to herringbone arrangement.Although not being shown in FIG. 36, at least one example, the pit on opposite sides of slit 3904 3906 can form the mirror reflection of the pit 3906 on the first side of longitudinal slit 3904.In other instances, staple forming surface The arrangement of pit 3906 in 3902 can be asymmetric relative to slit 3904, and in some instances, anvil block 3900 can not wrap Include longitudinal slit 3904.In various examples, pit 3906 can be arranged on each side of slit 3904 to be less than or more In three rows.

Pit 3906 shown in Figure 36 is identical.The each pit 3906 being limited in staple forming surface 3802 has Identical geometry.In other instances, the geometry of pit 3906 can along anvil block 3900 length it is by row and/or longitudinal Ground variation.For example, in some instances, the depth of pit 3906 or part thereof can change along the length of anvil block 3900, to adapt to Clearance distance between anvil block and nail bin along end effector and/or the length of flow of tissue variation, as described herein.

Exemplary crater 3906 is shown in 37-39C.Pit 3906b has first end or proximal end 3910 and the Two ends or distal end 3912.Proximal end 3910 and distal end 3912 of the pit axis PA (Figure 37) in pit 3906b Between extend.Pit 3906b includes periphery 3916, and periphery 3916 limits the boundary of pit 3906.Pit 3906b further includes nearside Cup 3920, distal side cup 3922, and the neck portion 3924 of connection nearside cup 3920 and distal side cup 3922.When nail be driven into When 3902 shaping contact of staple forming surface, nearside cup 3920 is aligned with nearside nail leg, and distal side cup 3922 and distal side nail leg pair It is quasi-.Cup 3920 and 3922 is configured to central part (such as neck by nail leg towards pit axis PA and pit 3906 Part 3924) it guides or transmits, and nail leg is made to be deformed into construction formed thereby.

Referring primarily to Figure 38, each cup 3920,3922 of pit 3906b limits inlet slope 3940 and exit ramp 3942.Exit ramp 3942 is steeper than inlet slope 3940.When forming nail, the tip of nail leg can enter along inlet slope 3940 Corresponding cup 3920,3922, and corresponding cup 3920,3922 is left along exit ramp 3942.In inlet slope 3940 and go out At vertex 3946 between mouth slope 3942, the tip of nail leg is deformed towards base portion the construction of forming, such as such as B is presented Shape or the B shape of modification.Nearside cup 3920 limits the non-shaped part relative to staple forming surface 3902 at its vertex 3946 The proximal depth D of 3908 measurements₁, and distal side cup 3922 limits at its vertex 3946 relative to the non-of staple forming surface 3902 The distal side depth D that shaped portion 3908 measures₂.In pit 3906, proximal depth D₁With distal side depth D₂It is equal.In other realities In example, proximal depth D₁With distal side depth D₂It can be different.Pit 3906b also nearside cup 3920 and distal side cup 3922 it Between neck portion 3924 in limit bridgeware 3944.The non-shaped part 3908 of bridgeware 3944 and staple forming surface 3902 is inclined It sets.More specifically, bridgeware 3944 is positioned in non-shaped 3908 lower section or recessed relative to non-shaped part 3908 of part.

Internal pit 5106a is identical, and intermediate pit 5106b is identical, and external pit 5106c is identical；However, inner-concave It is different from centre pit 5106b and outside pit 5106c to cheat 5106a, and centre pit 5106b and external pit 5106c are not Together.In other words, the pit 5106 in each row 5114a, 5114b and 5114c is different.In other instances, in row Pit 5106 in two or more can be identical.For example, internal pit 5106a can be identical as external pit 5106c. The extension touch-down zone 5130 and 5132 of pit 5106a, 5106b and 5106c described herein can help to its different geometry knot Structure.In addition, the shape and size for extending touch-down zone 5130 and 5132 are limited by the periphery 5116 of adjacent nested pit 5106.? Land area 5130 and 5132 limits curved profile.In other instances, touch-down zone 5030 and 5032 can be polygon and/or packet Include one or more linear and/or wavelike segmentss.

Although each row 5114a, the pit in 5114b and 5114c is different, and pit 5106 is configured to It is enough that nail is formed as into identical or substantially the same shaping form.In other instances, pit 5106 is configured to make Nail is configured to nail of different shapes, such as different height and/or construction.In some instances, pit 5106 can be in each row It is longitudinally varying in 5114a, 5114b and 5114c.For example, in some instances, the depth of pit 5106 or part thereof can be along anvil block 5100 length variation, to adapt to the clearance distance between anvil block and nail bin along the length of end effector and/or flow of tissue Variation, as described herein.

Exemplary intermediate pit 5106b is shown in Figure 68-71C.Pit 5106b has first end or proximal end 5110 and the second end or distal end 5112.Pit axis PA (Figure 69) is in the proximal end 5110 of pit 5106b and distal side Extend between end 5112.Pit 5106b includes periphery 5116, and periphery 5116 limits the boundary of pit 5106b.It wraps on periphery 5116 Include linear segment and wavelike segmentss.More specifically, wavy turning of the periphery 5116 including linear segment and therebetween, linear segment Change direction in the corner.Referring again to Figure 68, at least part on the periphery 5116 of each pit 5106 is closely tracked Or it is parallel at least part on the periphery of one or more adjacent pits 5106.The circular periphery 5116 of pit 5106b can mention For smoother profile, for example, its with have angular pit compared to can be imprinted more easily in staple forming surface 5102 with/ Or punching press.

Pit 5106b includes nearside cup 5120, distal side cup 5122, and is prolonged between nearside cup 5120 and distal side cup 5122 The neck portion 5124 stretched.When nail is driven into 5102 shaping contact of staple forming surface, nearside cup 5120 and nearside nail leg Alignment, and distal side cup 5122 is aligned with distal side nail leg.Cup 5120 and 5122 is configured to nail leg towards pit axis The guidance of the central part (such as neck portion 5124) of PA and pit 5106 or transmission, and nail leg is made to be deformed into structure formed thereby It makes.

Referring primarily to Figure 70, each cup 5120,5122 of pit 5106b limits inlet slope 5140 and exit ramp 5142.When forming nail, the tip of nail leg can be into corresponding pit 5120,5122 and oblique along outlet along inlet slope 5140 Leave corresponding pit 5120,5122 in slope 5142.At vertex 5146 between inlet slope 5140 and exit ramp 5142, nail The tip of leg is deformed towards base portion the construction of forming, such as the B shape of such as B shape or modification is presented.Pit 5106b is also close Bridgeware 5144 is limited in neck portion 5124 between side cup 5120 and distal side cup 5122.Bridgeware 5144 and non-shaped part 5108 biasings.More specifically, bridgeware 5144 is positioned in non-shaped 5108 lower section of part or relative to non-shaped part 5108 It is recessed.

Referring primarily to Figure 71 A-71C, pit 5106b includes side wall 5150, and side wall 5150 extends from non-shaped part 5108. Side wall 5150 includes linear segment and wavelike segmentss.Central area 5121 (figure of the side wall 5150 towards each cup 5120,5122 69) it broadens, and narrows from the central area 5121 of each cup 5120,5122 towards neck portion 5124.The center widened Domain 5121 provides the widened occupied area at the tip for receiving nail leg.When cup 5120,5122 is towards neck portion 5124 When narrowing, cup 5120,5122 is configured to transmit and/or guide its nail leg and tip towards and/or along pit axis PA And enter shaping structure.

Plane ALL interception of Figure 71 A in Figure 69, corresponds to the expection landing position of nail leg.Such as, it is contemplated that nail leg Tip plane ALL and pit axis PA infall and/or nearby land in nearside cup 5120.It is recessed at plane ALL It cheats 5106b and limits width W_AWith depth D_A.Transition of the cross section between nearside cup 5120 and neck 5124 in Figure 71 B is cut It takes.Figure 71 B, which is shown, limits width W_BWith depth D_BPit 5106b.Width W_BLess than width W_A, and depth D_BGreater than depth D_A.In other words, plane ALL of the pit 5106b proximally in cup 5120 narrows and deepens towards neck 5124.At plane ALL Relatively large width W_AIt is configured to provide the wide basin or container for receiving nail leg.Cross section in Figure 71 C across Neck portion 5124 intercepts.Figure 71 C, which is shown, limits width W_CWith depth D_CPit 5106b.Width W_CLess than width W_B, and And depth D_CLess than depth D_B.In other words, pit 5106b continues to narrow, and in the neck 5124 across bridgeware 5144 Become more shallow.

The bottom surface 5158 of pit 5106b is flat surfaces.In other instances, bottom surface 5158 can have along it at least The groove that a part limits.In other implementations, bottom surface 5158 can form slot and/or may include along its at least part (example As such as across bridgeware 5144) protuberance or ridge.

Referring now primarily to Figure 69, pit 5106b includes that nearside extends touch-down zone 5130 and distal side extension touch-down zone 5132. Nearside extends touch-down zone 5130 and is positioned in the portions of proximal of nearside cup 5120, and distal side extends touch-down zone 5132 and positioned In the distal part of distal side cup 5122.More specifically, extending the expection landing position that touch-down zone 5130 and 5132 is positioned in nail Except setting.For example, nearside extends the nearside that touch-down zone 5130 is positioned in plane ALL, and land at the tip of nail leg flat In example except the ALL of face, nearside, which extends touch-down zone 5130, can capture nail leg and be conducted towards pit axis PA and/or court To neck portion 5124.

The geometry for extending touch-down zone 5130 and 5132 is limited by the periphery 5016 of adjacent nail shapes pit 5106.Example Such as, extending touch-down zone 5130 and 5132 can extend towards one or more adjacent nail shapes pits and/or almost be adjacent Contact.The other parts for extending touch-down zone 5130 and 5132 and/or pit 5106b can be parallel to adjacent nail shapes pit 5106 Extend.In other instances, one or more adjacent nail shapes pits 5106 can be abutted by extending touch-down zone 5130 and 5132.

Referring again to Figure 69, pit 5106b is asymmetric about pit axis PA.For example, the periphery 5116 of pit 5106b is closed It is asymmetric in pit axis PA.In addition, pit 5106b is about across neck portion 5124 and perpendicular to the center of pit axis PA Axis CA is asymmetric.For example, the periphery 5116 of pit 5106b is asymmetric about central axis CA, and nearside cup 5120 has From distal side 5122 different geometries of cup.Although nearside cup 5120 and distal side cup 5122 are different, pit 5106b can It is configured to form symmetrical nail.For example, referring again to Figure 70, distal side depth D₂It is smaller than proximal depth D₁, to adapt to anvil The variation of seat and the clearance distance between nail bin and/or flow of tissue, as described herein.Therefore, the proximal leg and far leg of nail The forming height in portion can be equal.In other instances, pit 5106 is configured to form asymmetric nail.

Referring again to Figure 69, neck portion 5124 is narrower than nearside cup 5120 and distal side cup 5122.At neck portion 5124 The periphery 5116 of pit 5106b to narrow limits between a part of nearside cup 5120 and a part of distal side cup 5122 and receives Half island portion 5126.Half island portion 5126 is received to be positioned on each side of pit 5106b.Half island portion 5126 is received by pit The periphery 5116 of 5106b and tangent line axis are (for example, T_B1Or T_B2) define, on each side of the tangent line axis and pit 5106 Nearside cup 5120 and distal side cup 5122 widest portion it is tangent.First tangent line axis T_B1It is positioned in the first of pit 5106b On side, and the second tangent line axis T_B2It is positioned on the opposite side of pit 5106b.First tangent line axis shown in Figure 69 T_B1With the second tangent line axis T_B2Relative to pit axis PA deflection.In other instances, tangent line axis T_B1And T_B2In one or Two can be parallel with pit axis PA.

Referring again to Figure 68, the periphery 5116 of pit 5106 is nested along staple forming surface 5102 or interlocks.Specifically, each Pit 5106 extends in half island portion 5126 of reception of adjacent pit 5106.For example, centre pit 5106b is nested in internal pit Between 5106a and external pit 5106c.In other words, intermediate pit 5106b extends to the reception of adjacent inner pit 5106a In half island portion 5126 and extend in half island portion 5126 of reception of adjacent external pit 5106c.In addition, internal pit 5106a It is nested with centre pit 5106b with external pit 5106b.More specifically, inside pit 5106a extends to adjacent intermediate pit In half island portion 5126 of reception of 5106b, and outside pit 5106c extends to half island portion of reception of adjacent intermediate pit 5106b In 5126.In various examples, the distal side of intermediate pit 5106b extends touch-down zone 5132 and is positioned in internal pit 5106a's It receives in half island portion 5126, the nearside of intermediate pit 5106b extends the reception that touch-down zone 5130 is positioned in external pit 5106c In half island portion 5126, the distal side of internal pit 5106a extends the reception peninsula that touch-down zone 5132 is positioned in intermediate pit 5106b In portion 5126, and the nearside of external pit 5106c extends the reception peninsula that touch-down zone 5130 is positioned in intermediate pit 5106b In portion 5126.

The geometry of pit 5106 is convenient for nesting of the pit 5106 in staple forming surface 5102.For example, because pit 5106 include the neck portion 5124 to narrow between two widened cups 5120 and 5122, so another pit 5106 One in widened cup 5120,5122 may be positioned to the neighbouring neck portion 5124 to narrow.For example, widened cup 5120, One in 5122 can be aligned and/or be received with a part of adjacent pit 5106.In the illustration being described, can optimize by The surface region for the staple forming surface 5102 that pit 5106 covers.For example, the staple forming surface 5102 covered by pit 5106 Surface region is maximized." the forming ratio " of staple forming surface 5102 is non-shaped portion 5108 and shaped portion (that is, pit 5106) ratio.In at least one example, for example, forming ratio can be at least 1:1.In some instances, staple forming surface 60% or more of 5102 or 75% or more can be covered by nail shapes pit 5106.

Referring now to Figure 72-76C, the nail shapes pit 5206 in a part of anvil block 5200 is shown.Similar to anvil block 3800, pit 5206 is arranged to herringbone arrangement along the staple forming surface 5202 of anvil block 5200.Anvil block 5200 includes nail forming table Face 5202 and longitudinal slit 5204.Longitudinal slit 5204 extends along the longitudinal axis L A of anvil block 5200.In some instances, it fires Element and/or cutting element can translate across longitudinal slit 5204 during at least part of firing schedule.Nail shapes pit 5206 are limited in staple forming surface 5202.Staple forming surface 5202 further includes around the non-shaped part that pit 5206 extends 5208.Non-shaped part 5208 extends entirely around each pit 5206.In other words, non-shaped part 5208 is around nail forming Pit 5206.In other instances, at least part of two or more adjacent pits 5206 can abut contact so that it is non-at Shape part 5208 is not positioned between the two.

The forming ratio of staple forming surface 5202 can be optimized.By Optimize the forming scheme ratio, more nails are formable and/or are configured to Their desired constructions.In some instances, the surface region of the non-shaped part 5208 of anvil block 5200 can be shaped relative to nail Pit 5206 is minimized.In addition to this or alternatively, the occupied area of nail shapes pit 5206 is extensible or expands, with maximum Change the part for being designed to capture and formed nail of staple forming surface 5202.

Pit 5206 shown in Figure 72 is arranged to interior row 5214a, intermediate row on the first side of longitudinal slit 5204 5214b and outlet 5214c.Internal pit 5206a is located into row 5214a, and intermediate pit 5206b is positioned in intermediate row In 5214b, and outside pit 5206c is positioned in outlet 5214c.Although not shown in Figure 72, at least one reality In example, the pit on opposite sides 5206 of slit 5204 can form the mirror image of the pit 5206 on the first side of longitudinal slit 5204 Reflection.In other instances, the arrangement of the pit 5206 in staple forming surface 5202 can be asymmetric relative to slit 5204, and In some instances, anvil block 5200 may not include longitudinal slit 5204.In various examples, pit 5206 can be in slit 5204 It is arranged on each side fewer of more than three rows.

Pit 5206 shown in Figure 72 is identical.The each pit 5206 being limited in staple forming surface 5202 has Identical geometry.In other instances, the geometry of pit 5206 can along anvil block 5200 length it is by row and/or longitudinal Ground variation.For example, in some instances, the depth of pit 5206 can change along the length of anvil block 5200, to adapt to anvil block and nail Clearance distance between storehouse along end effector and/or the length of flow of tissue variation, as described herein.

Pit 5206 is configured to that the shaping form for being formed as identical or substantially the same will be followed closely.Such as this paper institute It states, pit 5206 is configured to each nail being formed as identical asymmetrically shape.In other instances, pit 5206 It is configured to that nail is made to be configured to nail of different shapes, such as different height and/or construction.

Exemplary intermediate pit 5206b is shown in Figure 73-76C.Pit 5206b has first end or proximal end 5210 and the second end or distal end 5212.Pit axis PA (Figure 72) is in the proximal end 5210 of pit 5206b and distal side Extend between end 5212.Pit 5206b includes periphery 5216, and periphery 5216 limits the boundary of pit 5206b.It wraps on periphery 5216 Include linear segment and wavelike segmentss.

Pit 5206b further includes nearside cup 5220, distal side cup 5222, and between nearside cup 5220 and distal side cup 5222 The neck portion 5224 of extension.When nail is driven into 5202 shaping contact of staple forming surface, nearside cup 5220 and nearside are followed closely Leg alignment, and distal side cup 5222 is aligned with distal side nail leg.Cup 5220 and 5222 is configured to nail leg towards pit axis The guidance of the central part (such as neck portion 5224) of line PA and pit 5206 or transmission, and nail leg is made to be deformed into structure formed thereby It makes.In other instances, cup 5222 can be in the nearside of cup 5220.

Referring primarily to Figure 70, each cup 5220 and 5222 of pit 5206b limits inlet slope 5240a and 5240b respectively And exit ramp 5242a and 5242b.When forming nail, the tip of nail leg can enter corresponding along inlet slope 5240a, 5240b Pit 5220,5222 and leave corresponding pit 5220,5222 along exit ramp 5242a, 5242b.Respectively in entrance At vertex 5246a between slope 5240a, 5240b and exit ramp 5242a, 5242b, 5246b, the tip direction nail of nail leg Base portion is deformed so that the construction of forming, such as the B shape of such as B shape or modification is presented.Pit 5206b is also in nearside cup 5220 and distal side Bridgeware 5244 is limited between cup 5222.Bridgeware 5244 and non-shaped part 5208 bias.More specifically, 5244 quilt of bridgeware It is located in non-shaped 5208 lower section or recessed relative to non-shaped part 5208 of part.

Referring again to Figure 73, pit 5206b is symmetrical about pit axis PA.For example, the periphery 5216 of pit 5206b about Pit axis PA is symmetrical.In addition, pit 5206b is about across neck portion 5224 and perpendicular to the central axis of pit axis PA CA is asymmetric.For example, the periphery 5216 of pit 5206b is asymmetric about central axis CA, and nearside cup 5220 have with it is remote Side 5222 different geometries of cup.The asymmetry of cup 5220 and 5222 is configured to form asymmetric nail.For example, Referring again to Figure 74, distal side depth D₂Less than proximal depth D₁, proximal depth D₁It is configured to be formed at proximal leg and has There is the nail of the forming height bigger than at the leg of distal side.Distal side depth D₂Than proximal depth D₁It is about 0.002 inch small.At it In his example, distal side depth D₂With proximal depth D₁Between difference can be greater than and/or less than 0.002 inch.In certain examples In, difference can be the 1% to 10% of nail diameter.For example, difference can be about the 2% of nail diameter.In other instances, nail Forming height is at the leg of distal side than bigger at proximal leg.The length of each cup 5220,5222 is also different.For example, remote Side length D₂Greater than the proximal length D in Figure 74₁.In addition, the inclination of inlet slope 5240a and 5240b in pit 5206b are Different, and the inclination of the exit ramp 5242a and 5242b in pit 5206b are also different.

In various examples, the reduced depth in a part of pit 5206b can improve the rigidity of anvil block.For example, because For distal side depth D₂Less than proximal depth D₁, so anvil block 5200 is made of more materials, this can increase its rigidity.In addition, because Increased material is located in the distal part of anvil block 5200, so this part can have increased rigidity, this can limit anvil block Towards the warpage or deformation of distal end.
