As depicted in figs. 1 and 2, the adapter 100 for hysteroscope stapler that one embodiment of the invention provides comprising outer
Shell 110, the nail bin connecting rod 120 being rotatably connected with shell 110, in shell 110 and with the motor of hysteroscope stapler
The transmission component of motor axis connection, is set in nail bin connecting rod 120 the driving transfer block 130 being movably arranged in shell 110
And with driving transfer block 130 connect percussion push rod 140, be fixed at drive transfer block 130 on the first trigger member 150, with
And it is fixed at the first approach switch 160 on shell 110.Wherein, percussion push rod 140 can be synchronous with nail bin connecting rod 120
Rotation.
The power of motor is passed to driving transfer block 130 by transmission component, makes to drive transfer block 130 along nail bin connecting rod
120 axial movement；The axial movement for driving transfer block 130 to drive percussion push rod 140 along nail bin connecting rod 120.
Percussion push rod 140 is moved to the first trigger member 150 relative to nail bin connecting rod 120 and triggers the first approach switch
160, the first approach switch 160 delivers a signal to the control unit of hysteroscope stapler.
First trigger member 150 triggers the first approach switch 160, and the first approach switch 160 delivers a signal to hysteroscope kiss
The control unit of clutch, it is out of service that control unit can control motor, so that percussion push rod 140 is accurately maintained at peace
Position is filled, convenient for the installation of nail bin groupware.
It should be noted that nail bin groupware is lucky when percussion push rod 140 is located at installation position relative to nail bin connecting rod 120
It can be fixedly connected simultaneously with percussion push rod 140 and nail bin connecting rod 120.
Specifically, the first approach switch 160 is optoelectronic switch in the present embodiment.Correspondingly, the first trigger member 150 is
Block piece.Preferably, the first trigger member 150 is integrally formed with driving transfer block 130.Certain first trigger member 150 can also pass through
The modes such as threaded connection, welding are fixed in driving transfer block 130.
Further, in this embodiment the first trigger member is also possible to grating.
In a further embodiment, the first approach switch is not limited to optoelectronic switch, can also be Hall switch, condenser type
Switch etc..Correspondingly, the first trigger member is magnetic part or conductor etc..
Preferably, in the present embodiment, shell 110 is equipped with the first operation portion (not shown).When first operation portion is operated,
Control unit control percussion push rod 140 can be made mobile and keep installation position.
Specifically, the first operation portion can be with touch screen or button etc..
In the present embodiment, adapter 100 further includes being fixed on shell 110 and being located at the first approach switch 160
The second approach switch 170 close to the side of nail bin groupware.It fires push rod 140 and is located at movement relative to nail bin connecting rod 120
The second approach switch 170 is triggered to the first trigger member 150, the second approach switch 170 delivers a signal to hysteroscope stapler
Control unit.It is out of service that control unit can control motor, so that percussion push rod 140 is accurately maintained at closure position,
At this point, control unit, which can control stapler, completes firing action.It is reset to correspondingly, completing shot movement when stapler
First trigger member 150 triggers the second approach switch 170, and the second approach switch 170 delivers a signal to the control of hysteroscope stapler
Unit processed, it is out of service that control unit controls motor, is maintained on closure position so that firing push rod 140, avoids percussion
Push rod 140 causes nail bin groupware to fall off because being moved to installation position.

When being located at closure position relative to nail bin connecting rod 120, the second trigger member triggers the second approach switch 170, and the second proximity is opened
Close 170 control units for delivering a signal to the hysteroscope stapler.
At this point, the first approach switch 160 and the second approach switch 170 can be the approach switch of identical type,
The structure of adapter is simple.Certainly, the first approach switch 160 and the second touch switch 170 are also possible to different types of
Approach switch.
It should be noted that should ensure that percussion pushes away when the first trigger member 150 can also trigger the second approach switch 170
In 140 moving process of bar, the first trigger member 150 is always positioned at the rear side of the second approach switch 170, to avoid the first triggering
150 the second approach switch of false triggering 170 of part.Correspondingly, when the second trigger member can also trigger the first approach switch 160
When, it should ensure that in percussion 140 moving process of push rod, the second trigger member is always positioned at the front side of the first approach switch 160, from
And avoid second the first approach switch of trigger member false triggering 160.
It in a further embodiment, only include an approach switch and a triggering for the adapter of hysteroscope stapler
Part, respectively the first approach switch 160 and the first trigger member 150, control unit can control percussion push rod 140 and be maintained at peace
Position is filled, equally also can control the movement of percussion push rod and is maintained at closure position.Specifically, the first trigger member 150 triggering first connects
Nearly formula switch 160, the first approach switch 160 deliver a signal to control unit, and control unit control percussion push rod 140 is along nail bin
The pre-determined distance moved axially forward of connecting rod 120, so that percussion push rod 140 is accurately kept relative to nail bin connecting rod 120
In closure position, so as to start the firing action of hysteroscope stapler.
Specifically, control unit can be by controlling the modes such as the runing time of motor or the rotating cycle of motor shaft, control
System percussion push rod 140 is along axial moving distance.
In this way, the structure of adapter can be made simpler, save the cost.
Correspondingly, in a further embodiment, the adapter for hysteroscope stapler can also only include a proximity
Switch and a trigger member, respectively the first approach switch 160 and the first trigger member 150 are opened by changing the first proximity
160 position is closed, when so that the first contact 150 triggering the first approach switch 160, control unit controls motor and stops fortune
Row, so that percussion push rod 140 is maintained at closure position.Control unit can control percussion push rod 140 and be maintained at closure position, equally
It can control the movement of percussion push rod 140 and be maintained at installation position.Specifically, the first contact 150 triggers the first approach switch
160, the first approach switch 160 delivers a signal to control unit, and control unit control percussion push rod 140 is along nail bin connecting rod
120 to move axially backward control motor after pre-determined distance to installation position out of service so that percussion push rod 140 is accurate
It is maintained at installation position, convenient for the installation of nail bin groupware.
Another embodiment of the present invention also provides a kind of hysteroscope stapler, including nail bin groupware, adapter provided by the invention
And handle.Wherein the nail bin groupware is detachably connected with the adapter.Specifically, the percussion of nail bin groupware and adapter
Push rod and nail bin connecting rod are detachably connected.
