The shell 74 of clutch and the first in command 1.
In order to realize the linkage of the first in command 1 and second handle 2, sliding slot 41 and sliding block are additionally provided on the first in command 1
42, sliding slot 41 includes the first segment 411 and second segment 412 being connected, and second handle 2 includes handle abutting portion 25；When sliding block 42
Positioned at the first segment 411 of sliding slot 41, and the first in command 1 is held when rotating in a second direction, sliding block 42 not with handle abutting portion
25 contradict, and second handle 2 is located at safety position, although that is, the first in command 1 rotates, but not fires stapler, in failure shape
State.In this embodiment, second direction is counter clockwise direction, however, the present invention is not limited thereto shown in figure.Therefore, doctor holds
When the first in command 1, the first in command 1 can be made to rotate easily, but without triggering second handle 2, simultaneously as being empty at this time
Cock, it is very small for holding the power of the first in command 1.Doctor can also recognize current stapler by this operating experience
State be that and not will cause the casing rupture of stapler in non-cock.
When sliding block 42 is located at the second segment 412 of sliding slot 41, and the first in command 1 is held when being rotated in the counterclockwise direction, sliding
Block 42 and handle abutting portion 25 contradict and second handle 2 are driven to rotate from safety position to firing position.When second handle 2 is along inverse
It when clockwise rotates, can push ejector pin bar 75 mobile to the distal end of stapler simultaneously, and then drive percussion stapler.
It should be noted that the first segment 411 and second segment 412 of heretofore described sliding slot 41 are a relative concepts,
And being not necessarily two ends of sliding slot 41, i.e., in visual angle shown in figure, the first segment 411 of sliding slot 41 is located at second segment
412 right side.Sliding block 42 holds the first in command 1, sliding block 42 and handle when being located at the first segment 411 and second segment 412 of sliding slot 41
The relationship of abutting portion 25 is different:, will not be dry with handle abutting portion 25 when sliding block 42 is located at the first segment 411 of sliding slot 41
When relating to, and being located at the second segment 412 of sliding slot 41, it will interfere with handle abutting portion 25.
In order to realize sliding of the sliding block 42 in sliding slot 41, the handle assembly of the embodiment further includes pointer.In the implementation
In example, pointer includes the first pointer 81 and the second pointer 82, and the first end 821 of the first pointer 81 and the second pointer 82 passes through pointer
Resetting structure is rotatably connected, and the first end 811 of the first pointer 81 is rotated from first position region to second along first direction
When setting region, the second end 822 of the second pointer 82 is driven to be rotated in a clockwise direction, and push sliding block 42 from the first of sliding slot 41
Section 411 is moved to the second segment 412 of sliding slot 41.In the embodiment, first direction be shown in figure clockwise, but this hair
It is bright without being limited thereto.Wherein correspond on stapler ontology and be equipped with a form at first position region and second position region, uses
In observing the first end 811 of the first pointer 81 the location of in use, the first end 811 of the first pointer 81 is first
It is in safety position when the band of position, stapler cannot fire at this time, when the first end 811 of the first pointer 81 is in the
When two bands of position, stapler can be fired, and in order to more intuitively to doctor to prompt, can fire the is corresponded on form
Two bands of position are green area.
The present invention can be applied not only to conventional circular-pipe anastomat, can also be applied to prepuce anastomat.Such as Fig. 3
It is shown, show the structure of the prepuce anastomat ontology 9 using the handle assembly.The distal end of prepuce anastomat ontology 9 includes nail
Storehouse component 91 is additionally provided with the glans penis cap assembly (not shown) cooperated with nail bin groupware 91.Using prepuce anastomat
When, second handle 2 is movably attached to one end of prepuce anastomat, the second end of second handle 2 and the ejector pin portion of prepuce anastomat
Part matches, and when condition can be fired by meeting, second handle 2 will push ejector pin component, realize the percussion of prepuce anastomat.
As Figure 10~12 show structure of the pointer under different conditions.The effect of pointer resetting structure is to maintain the first finger
When needle 81 rotates clockwise, the second pointer 82 can be driven to rotate clockwise simultaneously, i.e., pointer can rotate to dotted line in Figure 11
The position shown.It, then can be inverse relative to the first pointer 81 and when the second end 822 of the second pointer 82 is by active force to the right
Hour hands rotation, i.e. the second pointer 82 can rotate to position shown in phantom in Figure 12, however after active force to the right releases,
Second pointer 82 can return to initial solid line position by the restoring force of pointer resetting structure again.The purpose being arranged in this way is
In order to avoid referring to that the movement routine for sliding block 42 is formed and hindering when the first in command 1 and the linkage of second handle 2 rotate.When
When sliding block 42 is located at the second segment 412 of sliding slot 41 and the first in command 1 and rotates counterclockwise, sliding block 42 is rotated with, and is directed at this point, referring to
Sliding block 42 still has power to the left, and sliding block 42 can avoid pointer, and as the first in command 1 continues to rotate, sliding block 42 is supported with handle
After contact portion 25 contradicts, sliding block 42 cannot continue to avoid pointer due to being stopped by second handle 2, at this time if using can not deformation
Whole pointer, pointer will to the movement routine of sliding block 42 formed hinder so that second handle 2 rotation percussion process have some setbacks
Freely, user experience is bad.
Therefore, pointer is divided into two parts by the present invention: the first pointer 81 and the second pointer 82, sliding block 42 cannot continue to keep away
Allow pointer when, under the action of sliding block 42, the second pointer 82 can be rotated counterclockwise to avoid sliding block 42, this rotary course can make to refer to
Needle resetting structure is deformed, and after unclamping the first in command 1, under the restitution of pointer resetting structure, the second pointer 82
It can rotate clockwise again and return to initial position.Therefore, it adopts the structure, solves using whole pointer and cause stapler
The problem of handle motion has some setbacks when percussion, pointer at various locations when all will not influence the normal percussion of second handle 2, allow
In stapler design, pointer is interfered with other component, therefore the structure of small and exquisite stapler more compact may be implemented.
Figure 13~14 show a kind of specific structure of pointer in the embodiment.First pointer 81 includes first end 811, dashes forward
Portion 813, positioning region 814 and second end 812 out.Protruding portion 813 is corresponding with 61 position of drag hook of a pulling-on piece 6, and positioning region 814 can
The shell 74 of stapler is fixed in rotation.The tail portion 62 of pulling-on piece 6 is fixed on a screw rod 76 and can be with the movement of screw rod 76
And it moves.When knob 71 is rotated along a direction, screw rod 76 can be moved to the near end, and drive pulling-on piece 6 to move to the near end, the drawing of pulling-on piece 6
Hook 61 can drive the first pointer 81 to be rotated in a clockwise direction by protruding portion 813, so that the second equally rotation of pointer 82,
And then it is mobile from the first segment 411 of sliding slot 41 to the second segment 412 of sliding slot 41 with movable slider 42.

It is located at structure when failure state such as handle assembly that Figure 15~17 show the embodiment.Under the state, pulling-on piece 6
The first pointer 81 is not pulled, therefore the position of the first pointer 81 does not change, the first end 811 of the first pointer 81 is in first
Region is set, the second pointer 82 does not have active force to sliding block 42.Sliding block 42 is still located on the first segment 411 of sliding slot 41, in the first
In the rotating path of hand 1, sliding block 42 and the handle abutting portion 25 of second handle 2 are not interfered.It is noted that initial position
When sliding block 42 under the action of sliding block reseting pressuring spring 45 positioned at 41 first segment of sliding slot separate second segment the end illustrate the right side
End position.Can certainly be limited by the second end 822 of the second pointer 82 to the initial position of sliding block 42.In the reality
It applies in example, the first end 11 of the first in command 1 is grip part, and second end 12 includes interconnecting piece；The first end 21 of second handle 2 is located at
The inside cavity of interconnecting piece, second end 22 and ejector pin bar 75 contradict.At this point, instrument is in safety position.Due to the second torsional spring 34
Torsion it is much smaller compared with percussion force, the first in command 1, can be inverse around the first pin shaft 31 in curable grip lesser by operator
Hour hands rotation, second handle 2 go successively to the inside cavity of the first in command 1, i.e. the first in command 1 and second handle 2 is in and does not join
Dynamic state, second handle 2 do not rotate.Operator hold with a firm grip the first in command 1 when, can make easily the first in command 1 rotate, but
It is also just to be unable to complete the percussion of stapler without the rotation for driving second handle 2.It is anti-that operator can also obtain tactile at this time
Feedback, it is thus understood that current first pointer 81 do not reach can firing position, do not fire.When external force releases, the first in command 1 is second
It is resetted under the action of torsional spring 34.
Simultaneously as shown in figure 17, although sliding block 42 is contradicted with the second pointer 82 at this time, due to sliding block reseting pressuring spring 45
