The center line or axis axis location set, and for providing support during joint movement for percussion beam.This, which is different from using, " blows
Those of plate or lateral support plate construct out ", and in those constructions, these lateral support plates are located in the lateral side of percussion beam,
And thus from axis axis offset, their drawing forces experienced in joint motions process and compressing force are increased.Shown in
In example, can the flexible percussion beam assembly 2280 of longitudinal movement include lamination girder construction, which includes at least two
Beam layer, the lateral side that wherein at least one beam layer is configured to adjacent central percussion beam supporting member pass through, and
Another lateral side that at least one another beam is configured to adjacent central percussion beam supporting member passes through.Shown
Example in, every side that two laminate layers 2282 and 2284 are configured to neighbouring flexible tension bearing carrier passes through.Ginseng
See such as Figure 35 and Figure 36.In various embodiments, laminate layers 2282 and 2284 may include such as stainless steel band, these are stainless
Steel band is for example, by together interconnected amongst one another in the welding of its proximal end or pin joint, while their own distal end does not connect
It is connected together to allow layered product or band to open relative to each other when end effector does joint motions.Every a pair of laminate layers
Or band 2282,2284 is represented as the lateral percussion band component 2285 of percussion beam assembly 2280.Therefore, as shown in figure 36, one
Lateral percussion is supported in each lateral side of central joint motions stick 2286 with component 2285, passes through a series of sides to realize
It axially advances to load carrying component 2290 relative to it.Each lateral load bearing carrier 2290 can by such as stainless steel, aluminium,
Titanium, liquid crystal polymer material, plastic material, nylon, acronitrile-butadiene-styrene (ABS), polyethylene etc. are made, and are formed with
Opposite arcuate end 2292.Each lateral load bearing carrier 2290 also has the axial passageway 2294 extended through from it,
To receive component of the lateral percussion with component 2285 and central joint motions stick 2286.Such as it can most specifically see in Figure 38
As, each axial passageway is limited by two opposite arcuate surfaces 2295, the two arcuate surfaces 2295 are convenient for lateral negative
Lotus bearing carrier 290 is can movement on the flexible percussion beam assembly 2280 of longitudinal movement.Lateral load bearing carrier 2290 is gone here and there
It is arranged in connection on lateral percussion band component 2285 and central joint motions stick 2286, so that opposite arcuate end 2292 is adjacent
The correspondence arcuate end 2292 of adjacent side load carrying members 2290.See, for example, Figure 36 and Figure 37.
Referring again to Figure 37, it can be seen that the proximal end part 2288 of central joint motions stick 2286 extend downwardly with
It is attached to distal spine 2212.For example, the distal end 2287 of percussion beam assembly 2280 is attached to the percussion of the above-mentioned type and construction
Component 2900.As in this view, it may be seen that firing member 2900 includes hanging down with tissue cutting surface or blade 2904 on it
The fighting member body 2902 directly extended.In addition, wedge-shaped slides 2910 are mountable in surgery nail bin 2304, to drive and hit
Send out the contact of component 2900.When passing through warehouse 2304 towards distal side driving firing member 2900, the wedge shape of wedge-shaped slides 2910
Surface 2912 contacts staple drivers, thus upward actuator and the surgical staples being supported in nail bin 2304.Percussion
Beam assembly 2280 by it is above-mentioned it is various in a manner of operate.When percussion beam assembly 2280 is promoted around joint motions coila towards distal side,
Lateral load bearing carrier 2290 can help to resist the bending load on percussion beam assembly 2280.Lateral load bearing carrier 2290
The amount of power needed for making end effector can also be reduced, and may be used also compared with other actuated articulation joints construction
Accommodate bigger articulation angle.Fixed center percussion beam supporting member 2286 is for being carried on joint motions and percussion phase
Between the tensioning load that generates.
As described above, percussion beam assembly includes lamination girder construction, which includes at least two beam layers.Work as percussion
When beam assembly (during percussion) is promoted towards distal side, percussion beam assembly is substantially divided into two by center percussion beam supporting member
Point, so that a part (that is, laminate layers) of percussion beam assembly passes through on the two sides of center percussion beam supporting member.
Figure 40 to Figure 43 shows a part for being attached to another percussion beam assembly 2280' of firing member 2900.From that
As can be seen that percussion beam assembly 2280 includes laminar structure in a little figures, which includes respectively having to be designated as " a "
The two outer layer curb girders or layer 2282' of thickness, and respectively there are four central core 2284' of the thickness for being designated as " b ".Example
Such as, at least one construction, " a " can be about 0.005-0.008 inches, and even more preferably from 0.008 inch, and " b " can
To be about 0.008-0.012 inches, even more preferably from 0.010 inch.However, other thickness can be used.In the example shown,
" a " is less than " b ".In other constructions, " a " is greater than " b ".For example, layered product can be by three kinds of different thickness in alternative configuration
" a ", " b ", " c " composition are spent, wherein " a "=0.006 inch, " b "=0.008 inch, and " c "=0.010 is inch (most thick
Layered product or band are at the center of component).In various constructions, it is understood that there may be odd number layered product or band, wherein " c " is at center
Locate the most thick layered product of single layer.
The composition of layered product has significant role, because the amount for the strain being applied on beam assembly is based on its thickness and apart from curved
The distance of bent center line.Closer to center line compared with thick-layer laminate or with possible experience and relatively thin layered product farther from center line
Or with identical strain level, since it is considered that the fact that they stack together, they must be more curved.Curve from center
Radius of curvature on the farther inside of line is bigger.Identical radius of curvature is given, thicker layered product or band tend to than relatively thin
Layered product be subjected to more internal stress.Therefore, relatively thin side layered product or band with the smallest radius of curvature may have with
Close to the plastic deformation possibility identical compared with thick-layer of center line.In other words, when end effector closes in one direction
When section movement, layered product or band far from joint motion direction positioning have maximum bending radius, near joint motions side
To layered product or band have most tight bending radius.But, when end effector does joint motions in the opposite direction, feelings
Condition is exactly the opposite.Layered product stacks internal layered product and undergoes identical deviation, but their bending radius will be fallen in always
In the range of external layer lamination body.Therefore, in order to keep flexibility, it may be necessary to which relatively thin layered product is located in the outer layer stacked
On.But in order to improve rigidity and bending resistance to the maximum extent, internal thicker material can bring additional benefit.Optionally
Ground, if end effector only needs to do joint motions in a single direction, the layered product far from joint motion direction positioning
Or band will undergo maximum bending radius, and be located in the layered product in joint motion direction or band with most tight bending half
Diameter.But, since end effector does not do joint motions in the opposite direction, inversion condition is no longer set up, so layered product
It stacks and needs not be symmetrical.Therefore, in such configuration, it is desirable to which most thin layered product or band will will undergo most tight bending
The layered product or band (layered product or band on joint motion direction side) of radius.
In other constructions, layered product or band can be made of the different metal with varying strength and modulus.For example, outer
Portion's layered product or band can have thickness identical with the thickness of internal layered product or band, wherein internal layered product or band are by 300
Series stainless steel is made, and external layered product or band are made of titanium or Nitinol.
As in Figure 42 and Figure 43 it can also be seen that distal side percussion beam assembly 2280' can be with a series of above-mentioned lateral loads
Lotus bearing carrier 2290 is effectively used together.It should be appreciated that distal side percussion beam assembly 2280 can also in the above described manner with center
Joint motions stick 2286 is used in combination, so that its some layers or curb girder (or band or layered product) are along central joint motions stick
Side axial promotes.In some embodiments, the layer promoted on every side of central joint motions stick 2286 can have phase
Same thickness, composition, shape and configuration.In other constructions, one or more passed through along the side of central joint motions stick
A layer can have with the thickness of one or more layers and/or composition passed through along central joint motions stick opposite side and/or
Variform thickness and/or composition and/or shape to realize desired travel range and flexibility, while keeping it is expected
Rigidity amount to avoid the buckling during percussion.
