In such situation, latching member 21780 is disposed in response to another latching member, to prevent the propulsion of nail trigger system.Change sentence Words say that latching member 21780 may include auxiliary locking part, and the auxiliary locking part and main latching member are co-operated to prevent nail percussion system The propulsion of system.

In all cases, than that described above, latching member 21780 can provide overload protection to nail trigger system.For example, nail Trigger system can block during firing schedule, and can dispose latching member 21780 to stop following closely firing schedule.In such case Under, at least part of percussion force or percussion force can be transmitted to axis 21730 rather than nail bin by latching member 21780.Therefore, it is latched Part 21780 can prevent trigger system and/or nail bin to be damaged or at least further damaged.In such cases, in response to pre- Determine the situation deployment latching member 21780 of the suturing assembly except latching member.Referring again to Figure 82 and Figure 83, rack gear 21781 is phase With length or be longer than nail trigger system first stroke so that latching member 21780 can be engaged in any point during firing schedule Rack gear 21781.

When proximally firing member 21760 falls below force threshold to the power that distal side firing member 21762 transmits, spring 21785 can flexibly by hammerlock 21782 be back to its unlocked configuration and with the driving surface of distal side firing member 21,762 21768 Engagement.At this point, if the condition for causing auxiliary locking part 21780 to activate has weakened, achievable firing schedule.Otherwise, nearside is hit Hair component 21760 can be retracted.

Turning now to Figure 92-95, loading unit includes axis 24530 and the nail trigger system for extending through axis 24530.Nail is hit Hair system includes nearside firing member 24560 and distal side firing member 24562.During the nail firing schedule of nail trigger system, Nearside firing member 24560 is pushed by such as electric motor and/or hand-crank towards distal side.Equally, distal side firing member 24562 It is pushed by nearside firing member 24560 towards distal side.Following closely trigger system further includes that proximally positioned firing member 24560 and distal side are hit Send out the latching member 24580 among component 24562.Latching member 24580 is configured to percussion force during following closely firing schedule Proximally firing member 24560 is transferred to distal side firing member 24562.Latching member is transmitted through during following closely firing schedule 24580 power is more than expected percussion force, and/or more than in the case where predetermined threshold force, latching member 24580 enters lock Configuration is determined, as shown in Figure 94 and Figure 95.

Referring primarily to Figure 93 and Figure 95, latching member 24580 includes such as generally C-shape configuration, which surrounds distal side A part of firing member 24562 extends.Latching member 24580 includes hammerlock 24584, is not activated when latching member 24580 is in it Or when unlocked configuration, these hammerlocks clamp distal side firing member 24562, as shown in Figure 92 and Figure 93.Latching member 24580 further includes When nearside firing member 24560 drives during the nail firing schedule for following closely trigger system towards distal side by nearside firing member The driving tab 24582 of 24560 contacts.When latching member 24580 is pushed by nearside firing member 24560 towards distal side, latching member 24580 abut against the driving surface 24564 limited on distal side firing member 24562 and push distal side firing member towards distal side 24562.Therefore, by hammerlock 24584, by thrust, proximally firing member 24560 is transferred to driving surface to latching member 24580 In 24564.

Referring primarily to Figure 92, drive tab 24582 not coplanar with hammerlock 24584；On the contrary, driving tab 24582 from by The plane that hammerlock 24584 limits extends laterally.More specifically, at least when latching member 24580 is in its non-actuated, driving Tab 24582 includes the raised portion overturn from hammerlock 24584.As long as latching member 24580 is configured to be transmitted through latching member 24580 thrust is just able to maintain lower than threshold force in its non-actuated.Motive force needed for completing firing schedule is lower than The threshold force.When the motive force by transmission latching member 24580 is more than threshold force, latching member 24580 is shrunk to it and activates structure Type, as shown in Figure 94 and Figure 95.For example, when the missing nail bin in the adjacent such as nail bin of distal side firing member 24562 and/or having made When with nail bin latching member, motive force can exceed that threshold force.

Referring again to Figure 94 and Figure 95, when latching member 24580 is moved to its actuated, hammerlock 24584 is radially outward Expansion is to engage axis 24530.In at least one situation, axis 24530 may include being defined in recessed portion 24534 therein, this is recessed Concave portion is configured to receive hammerlock 24584.Recessed portion 24534 is limited in axis 24530, so that working as the distal side of trigger system When the storehouse lacked and/or used storehouse latching member being promoted to prevent, hammerlock 24584 is aligned with recessed portion 24534.Once hammerlock 24584 in recessed portion 24534, and the distal side that latching member 24580 prevents from trigger system promotes.In all cases, Recessed portion 24534 is positioned and arranged to stop firing member before the cutting element incision tissue of percussion driving device 24560.When nearside firing member 24560 bounce back and be applied to latching member 24580 promotion load be brought down below threshold force when, Latching member 24580 can be resiliently return toward its non-actuated.At this point, not used storehouse can be placed in loading unit to allow The storehouse of missing and/or the failure of used storehouse latching member promote so that trigger system can follow closely firing schedule by it towards distal side.But At any point, nearside firing member 24560 can bounce back with the distal side firing member 24562 that bounces back.

If nail trigger system accelerates too quickly, the threshold force of above-mentioned latching member can be activated.In other words, nail percussion Acceleration peak value in system can lead to power peak value, which exceeds the threshold force of latching member, this makes latching member stop nail Trigger system.When the firing trigger for being mechanically coupled to nail trigger system is suddenly applied to by too fast extruding and/or power supply Such as it is possible that such situation when following closely the electric motor of trigger system.In at least one situation, acceleration peak value can be Such as be applied to electric motor power supply improperly modulated and/or when software fault occur in motor controller when hair It is raw.This acceleration peak value and power peak value be usually transient state and firing schedule can be transmitted through nail trigger system power drop Return to completion when lower than threshold force.
