Danger button 1 is in off-position, as shown in fig. 6, now, ratchet 31 will be sent out before the tooth bar 21 with actuator 2 is engaged with safety fastener 1
Raw interference；When close connecting rod 5 by nearside distal direction movement carry out shutoff operation when, safety fastener 1 with close connecting rod 5 distad
Direction is moved, and safety fastener 1 is moved to open position after the end effector for closing the driving surgical operating instrument of connecting rod 5 is closed, such as
Shown in Fig. 7, now, ratchet 31 can be realized to be engaged with tooth bar 21.
Mode three, the closing connecting rod 5 of safety fastener 1 and surgical operating instrument is connected, and safety fastener 1 drives in closing connecting rod 5
It can switch over, can also be accomplished in the following manner between its open position and off-position under dynamic：
As shown in figure 8, passing through leading that at least one pair of is slidably matched between safety fastener 1 and the fixed handle of surgical operating instrument
Connected to groove and sliding block, by taking Fig. 8 as an example, gathering sill 6 is arranged on fixed handle, and sliding block 15 is formed on safety fastener 1, gathering sill
6 length direction is vertical with the axial line of surgical operating instrument slender bodies；Pass through a pair of pin between safety fastener 1 and closing connecting rod 5
Axle and pilot hole drive connection.
By taking orientation shown in Fig. 8 as an example, being slidably matched between sliding block 15 and gathering sill 6 makes the safety fastener 1 can only be relative to fixation
Handle is moved along the vertical direction；In structure shown in Fig. 8, close connecting rod 5 and closing motion now is not carried out to end effector, now
Safety fastener 1 is in off-position；When needing to close the driving end effector closing of connecting rod 5, the side shifting to the left of connecting rod 5, insurance are closed
Button 1 by the cooperation of pilot hole 51 and bearing pin when closing under the driving of connecting rod 5 under guiding of the safety fastener 1 along gathering sill 6 upwards
Open position is moved to, switching of the safety fastener 1 by off-position to open position is realized；In addition, when safety fastener 1 is in open position, now closing connecting rod 5
In the state for closing end effector, when closing connecting rod 5 is acted by distal side proximal direction, safety fastener 1 is in pilot hole
51 and bearing pin driving under and be moved downward to off-position under the guide effect of sliding block 15 and gathering sill 6, realize safety fastener 1 by
Open position to off-position switching.
In aforesaid way three, sliding block can also be arranged on fixed handle, and gathering sill is formed on safety fastener (in figure not
Show).
Preferably, in mode three, between safety fastener 1 and closing connecting rod 5, bearing pin can be arranged on safety fastener 1, pilot hole
51 are arranged on closing connecting rod 5, and bearing pin stretches into pilot hole 51.
It is, of course, also possible to be that pilot hole is arranged on safety fastener 1, and bearing pin is arranged on closing connecting rod 5, and bearing pin is stretched into
Pilot hole (not shown).
Obviously, those skilled in the art can carry out various changes and modification without departing from this hair to the embodiment of the present invention
Bright spirit and scope.So, if these modifications and modification of the present invention belong to the claims in the present invention and its equivalent technologies
Within the scope of, then the present invention is also intended to comprising including these changes and modification.
