The present invention provides a kind of handle assemblies of new percussion for stapler.To achieve the goals above, it solves
Handle assembly is segmented by handle in the prior art, the present invention, is divided into the first in command 1 and second handle
2, the first in command can be rotated by external force, but kiss can be fired by being only only when second handle 2 is rotated along specific direction
Clutch.Wherein, the first in command and second handle have linkage status and not linkage status.The first in command and second
Handle is in not linkage status, and when the first in command is rotated in a first direction, the second handle does not rotate, and will not fire
The stapler；The first in command and second handle are in linkage status, and when the first in command is rotated in a first direction,
The first in command drives the second handle to be rotated in a first direction, to fire the stapler.
Therefore, the present invention is by being divided into the first in command and second handle, the only movement of second handle just for handle assembly
Stapler can be fired and execute cutting and suture movement；In use, no matter stapler whether reach can firing position, doctor
Life can press the first in command, however, stapler not up to can cock when, the first in command will not drive second
Hand would not also fire stapler.
The structure of handle assembly of the invention is further described below with reference to several specific embodiments.But it is intelligible
It is the structure and working condition for being described below handle assembly in order to better illustrate the present invention, only as handle of the invention
The preferred embodiment of hand component, and should not be used as the limitation of protection scope of the present invention.
First embodiment
As shown in Figure 1, the handle assembly further includes the control first in command 1 and the linkage shape of second handle 2 in the embodiment
The pointer 4 of state.Wherein:
Pointer 4 is equipped with first end 41, second end 42 and fixing end 43, and the second end 42 of pointer 4 is associated with the distal end of pulling-on piece,
The proximal end of pulling-on piece is sheathed on screw rod, and the proximal end of screw rod is connected with knob.Knob is rotated, pulling-on piece can be made to drive pointer second end 42
It is moved between first position region and second position region, wherein corresponding to first position region and the on stapler ontology
A form is equipped at two bands of position, for observing the location in use of pointer second end 42, pointer second end
42 at first position region, is in safety position, and stapler cannot fire at this time, when pointer second end 42 is in second
When the band of position, stapler can be fired, in order to correspond to can fire second on form more intuitively to doctor to prompt
Band of position L is green area, and the prior art has had announcement；
The first in command 1 is provided with elastic portion 3；The second end 42 of pointer 4 is moved to second position area from first position region
When domain, the first end 41 of pointer 4 contacts with elastic portion 3 and elastic portion 3 is driven to enter the second state, first state from first state
It is the state before elastic portion 3 is not contacted with pointer 4, the second state is state when elastic portion 3 is contacted with pointer 4；
Elastic portion 3 is in first state, and when the first in command 1 is rotated in a first direction, elastic portion 3 not with second handle 2
It contradicts, second handle 2 is in safety position, i.e., does not fire to stapler；Elastic portion 3 is located at the second state, and the first
When hand 1 is rotated in a first direction, elastic portion 3 and second handle 2 contradict and drive second handle 2 from safety position to firing position
Mobile, i.e., in this case, elastic portion 3 can push second handle 2 and then carry out the percussion of stapler.In Fig. 1, first party
To for counterclockwise.
For the second end 42 of pointer 4 at first position region and second position region, the movement of the first in command 1 is to second
Influence caused by hand 2 is different.The second end 42 of pointer 4 is at first position region, since elastic portion 3 is in the first shape
State, elastic portion 3 do not contact during the motion with second handle 2, and active force would not be also generated to second handle 2, second
Hand 2 still keeps original state, instrument will not be driven to fire；The second end 42 of pointer 4 is at second position region, due to elastic portion
3 are in the second state, when elastic portion 3 is rotated with the rotation of the first in command 1, will push the movement of second handle 2, that is, drive second
Handle 2 drives instrument percussion.Therefore, pass through the position of change pointer 4, it can the phase of the control first in command 1 and second handle 2
Mutual matching relationship.
To sum up, when stapler does not carry out percussion preparation, the second end 42 of pointer 4 is in the first position region, this
When, if doctor holds the first in command 1, the first in command 1 can be made to rotate easily, but without triggering second handle 2, because thus
