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 pointer 81 and the second pointer 82 are integrally formed or first refers to
Needle 81 is fixedly connected with the second pointer 82, and the second pointer 82 is elastic pointer.When the first end 811 of the first pointer 81 is along
When one direction is rotated from first position region to second position region, drive the second end 822 of the second pointer 82 along side clockwise
To rotation, and sliding block 42 is pushed to be moved to the second segment 412 of sliding slot 41 from the first segment 411 of sliding slot 41.In the embodiment, first
Direction is clockwise direction, however, the present invention is not limited thereto shown in figure.Wherein correspond to first position on stapler ontology
A form is equipped at region and second position region, the first end 811 for observing the first pointer 81 is locating in use
Position, the first end 811 of the first pointer 81 is in safety position, stapler cannot at this time at first position region
Percussion, when the first pointer 81 is in second position region, stapler can be fired, in order to more intuitively to doctor to prompt,
The second position region that corresponding on form can fire is 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

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 Fig. 7~10 show structure of the pointer under different conditions.It, can be simultaneously when first pointer 81 rotates clockwise
The second pointer 82 is driven to rotate clockwise, i.e., pointer can rotate to position shown in phantom in Fig. 8.And when the second pointer 82
It, then can be relative to the first rotation counterclockwise of pointer 81, so that the second pointer 82 generates when second end 822 is by active force to the right
Flexible deformation, i.e. the second pointer 82 can rotate to position shown in phantom in Fig. 9, however after active force to the right releases,
Second pointer 82 can restore the reset condition as shown in solid line in Fig. 9 by the elastic characteristic of itself again.It is arranged in this way
Purpose is in order to avoid in the first in command 1 and the rotation of second handle 2, referring to that the movement routine for sliding block 42 is formed and hindering.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 that can not generate
Elastically-deformable entirety pointer, pointer, which will be formed the movement routine of sliding block 42, to be hindered, so that the rotation of second handle 2 fires
Process has some setbacks, and 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 end 822 of the second pointer 82 can be rotated counterclockwise to avoid sliding block 42, this rotation
Turning over journey can make the second pointer 82 generate flexible deformation, and after unclamping the first in command 1, in second pointer 82 elastic characteristic itself
Under the action of, the second pointer 82 can rotate clockwise again returns to initial position.Therefore, it adopts the structure, before solving
The problem of handle motion has some setbacks when causing stapler to fire using whole pointer, pointer at various locations when all will not influence
The normal percussion of second handle 2 allows when stapler designs, and pointer is interfered with other component, therefore may be implemented more
Step up to gather the structure of small and exquisite stapler.Second pointer 82 can be made of elastic resin, rubber material or metal material, but
Without being limited thereto, other are with certain rigidity and there is the material of elastic characteristic also can according to need selection.
Figure 11~12 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,

Plus-pressure makes it generate deformation.
It is located at structure when failure state such as handle assembly that Figure 13~14 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.
