Relative to and/or around pod when being configured to slide in the channel 8103 in connector shell 8102 in bracket 8104
8130 movements and/or displacement.
Referring primarily to Figure 71, pod 8130 may include at least one flexible tabs 8132a, 8132b.Flexible tabs
8132a, 8132b can be inward towards 8136 biass that are open, and/or for example may include the tooth of inward bias.In certain situations
Under, flexible tabs 8132a, 8132b may include tooth 8133, for example, the tooth can be configured to insert in drive rod 8172
When entering in the opening 8136 in pod 8130, the groove 8174 in drive rod 8172 is engaged.For example, the inclined-plane of drive rod 8172
8176 can be by the tooth 8133 in open socket 8136, and can tab 8132 be bent or be deflected outward from opening 8136.
When drive rod 8172 goes successively to the opening 8136 of pod 8130, the tooth 8136 of tab 8132a, 8132b are engageable or catch
Groove 8174 in drive rod 8172.In this case, for example, the engagement of tooth 8136- groove 8174 can release drive rod 8172
It is maintained at putting in pod 8130.
In all cases, for example, pod 8130 may include groove 8134, which can be configured to receive
Spring 8150.In other cases, for example, pod 8136 may include more than one groove 8134 and coupling configuration 8100 can
To include more than one spring 8150.In addition, in some cases, pod 8130 may include more than one flexible tabs
8132a,8132b.For example, pod 8130 may include a pair of of lateral register tab 8132a, 8132b.First tab 8132a
It such as can be positioned on the first cross side of pod 8130, and the second tab 8132b for example can be positioned on the second of pod 8130
On cross side.In some cases, for example, tab 8132a, 8132b can be deflected outward from opening 8136, it is suitable for drive rod
8172 enter.In other cases, for example, pod 8130 may not include inward bias tab and/or may include more than two
Tab.
In all cases, coupling configuration 8100 may also include latch or casing 8140, and the latch or casing can be opposite
It is movably positioned in pod 8130.For example, latch 8140 may include opening 8142 (Figure 72), the size and structure of the opening
It can be configured at least part of at least partly about pod 8130.For example, latch 8140 can be positioned around pod 8130,
And it such as can movably be positioned relative to the tab 8132a of pod 8130,8132b.In all cases, for example, spring
8150 can be positioned between a part of pod 8130 and a part of latch 8140, enable spring 8150 by latch 8140
Towards pod-latch position (Figure 68) bias.For example, latch 8140 can be biased into pod-latch position (Figure 68) by spring 8150
In, in the position, latch 8140 is oriented to surround and/or constrain tab 8132a, and 8132b's is deflected outward.
In all cases, for example, when latch 8140 is oriented to limit and/or prevent tab 8132a, 8132b to
Extrinsic deflection, that is, when being in pod latch position, tab 8132a, 8132b are moved out and can be restricted far from opening 8136,
So that tab 8132a, 8132b can be prevented and/or otherwise be prevented drive rod 8172 relative to opening in pod 8130
Mouth 8136 enters and/or release.In addition, for example, when trigger 8120 moves to actuated position (figure from unactuated position (Figure 68)
67 and Figure 69) when, latch 8140 can overcome the bias of spring 8150, and can move to from pod latch position (Figure 68)
Unlatched position (Figure 67 and Figure 69).Latch 8140 is displaceable when being in unlatched position to leave flexible tabs 8132a,
8132b, so that such as flexible tabs 8132a, 8132b can be deflected outward, and for example pod 8130 can receive drive rod
8172。
In all cases, latch 8140 may include convex block or protrusion 8144.In addition, referring primarily to Figure 70, connector
Bracket 8104 in shell 8102 may include biasing member 8108.For example, biasing member 8108 may include slope or angulation
Spend surface, the slope or angled surface can be for example configured to first or pod-latch position (Figure 67 and figure
69) the bias convex block 8144 between second or latch position (Figure 68), thus bias latch 8140.For example, working as trigger
When 8120 movement causes bracket 8104 to shift relative to connector shell 8102 and pod 8130, as described herein, convex block
8144 can slide along the angled surface of biasing member 8108, so that flexible tabs 8132 of the latch 8140 relative to pod 8130
Movement.In this case, the starting of trigger 8120 can overcome the bias of spring 8150 and make latch 8140 from around holding
Pod-latch position of the flexible tabs 8132 of nest 8130 bounces back to unlatched position.In this case, when latch 8140 returns
When contracting, the deflection of flexible tabs 8132 and/or engagement drive rod 8172 are allowed.In addition, for example, when trigger does not activate, bullet
Spring 8150 can relative to and/or surround flexible tabs 8132a, 8132b bias latch 8140, so that limitation and/or preventing tab
8132a, 8132b deflection are to limit and/or prevent the engagement with drive rod 8172.
In some cases, latch 8140 may include a pair of laterally opposed convex block 8144, this to convex block slideably
Engage the laterally opposed biasing member 8108 of bracket 8104.In addition, in coupling configuration 8100 in shank 8170 and surgical end
When coupling more than one drive system between actuator, for example, bracket 8104 may include multiple biasing members 8108 and/or more
To biasing member 8108.For example, each pod 8130 may include the convex block 8144 of a pair of of lateral register, and such as bracket
8104 may include the biasing member 8108 for each convex block 8144.
Referring primarily to Figure 68, before startup trigger 8120 and/or when discharging trigger 8120, trigger 8120 can be determined
In distal side unactuated position, bracket 8104 can be located in raised position, and latch 8140 relative to connector shell 8102 for position
It can be positioned on pod-latch position.In such construct, for example, latch 8140 can prevent drive rod 8172 from entering pod
It 8130 and/or is engaged with pod 8130.In all cases, for example, spring 8150 and/or different springs and/or biasing member
Trigger 8120 can be biased into unactuated position, bracket 8104 can be biased into raised position, and/or can will fastened with a bolt or latch
Lock 8140 is biased into pod-latch position.In order to one in drive rod 8172 be connected and/or be attached in pod 8130
One, referring now to Figure 67, for example, trigger 8120 is moveable to nearside actuated position, this can be shifted bracket 8104
To more lower position, so as to which latch 8140 is displaced to unlatched position.In such construct, for example, drive rod 8172 can
To be configured to enter pod 8130 and/or be received by the pod.
Hereafter, if release trigger 8120, referring now to Figure 68, for example, spring 8150 can be inclined by trigger 8120
Distal side unactuated position is pushed back, bracket 8104 can be biased to return to raised position, and latch 8140 can be biased to return to pod-
Latch position.Thus, for example, 8172 lockable of drive member is at engaging socket 8130, because latch 8140 can prevent flexibility
Tab 8132a's, 8132b is deflected outward, and therefore drive member 8172 can be fixed in pod 8130.Therefore, existing
Referring to Figure 69, in order to separate drive member 8172 with pod 8130, caused for example, trigger 8120 can move to nearside again
Dynamic position, bracket 8104 can be displaced to more lower position by this, so as to which latch 8140 is displaced to unlatched position.Herein
In class construction, that is, when pod 8130 is not latched, for example, drive member 8172 can be removed from pod 8130.
In all cases, surgical instruments may include the drive system for being attached to motor.In some cases, the motor
Various surgical functions can be influenced with drive system.For example, the motor and drive system can influence surgical end-effector
It opens and/or is closed, and can for example influence cutting and/or firing schedule.In some cases, the motor and drive system
It can influence a variety of different surgical functions.For example, the opening and/or closure of surgical end-effector can independently of or be different from come
From the cutting and/or percussion of the fastener of surgical end-effector.In this case, drive system may include transmission and/
Or clutch pack, for example, the transmission and/or clutch pack can move being bonded between different output systems for drive system
Position.
In all cases, surgical instruments may include drive system, which has multiple output shafts and be used for
The clutch shifted between different output shafts.In some cases, which can correspond to different surgical functions.For example,
First output shaft can correspond to end effector closing motion, and such as the second output shaft can correspond to end effector percussion
Movement.In all cases, for example, drive system can engaged with the first output shaft and cut between engaging with the second output shaft
It changes, so that surgical function is separated and different and/or independent.For example, end effector closing motion can independently of and
It fires and moves different from end effector.For example, causing closing motion and causing individually percussion when completing closing motion
Movement can be preferred.In addition, for example, controlling and/or driving using the single drive system that may be coupled to electric motor and is only
Vertical closing motion and percussion movement can be preferred.In other cases, first output shaft and the second output shaft can
