Dynamic wobble component.Input shaft is extend out to outside shell 1, for connecting with the extraneous driving device such as motor.Gear-box 7 can make
In the case where with a motor, while driving wheel 2 and wobble component being driven to work.
Since conduit driving mechanism provided in this embodiment is mainly used for medical operating field.When being performed the operation,
Medical instrument is asked to need to reach enough disinfection standards.Part is more in the shell 1 of existing some conduit driving mechanisms, can not
Thoroughly disinfected, so belong to disposable products.And the motor of existing conduit driving mechanism is all mounted to inside shell 1
's.So operation is at high cost, will cause very big waste.
And conduit driving mechanism provided in this embodiment, it is not provided with the driving devices such as motor in shell 1, but by by tooth
The input shaft of roller box 7 is extend out to outside shell 1, and external motor is arranged in connection.In this way, after surgery, only shell 1 need to be handled
Fall.It does not need together to discard motor, reduces operation cost, reduce waste.
Simultaneously as the required precision that glaucoma glues small Tuboplasty opponent art operation is high, and existing conduit drives
Mechanism, since motor is arranged inside shell 1, and the parameter of the motor in the device of different batches is not also identical, so it is each
Secondary operation consent, which has, re-scales motor, to guarantee the demand to the precision of surgical procedure.It is provided in this embodiment to lead
Pipe driving mechanism, due to being not provided with motor inside shell 1, but the motor outside using.So can be every time using same
A motor is operated.In this way, avoiding the problem of each operation consent will demarcate motor.Considerably increase operation
Efficiency.
Further, in the present embodiment, the axis of the first output shaft 6 is parallel with the axis of input shaft.Specific first
Output shaft 6 and input shaft can be same axis, be called main shaft in this implementation, be the first input close to one end of driving wheel 2
Axis, extending out to one end outside shell 1 is input shaft, rotates synchronously the first output shaft 6 and input shaft.Specific connection
When, driving wheel 2 is connect by drive shaft 5 with the first output shaft 6.
The axis axis of second output shaft 8 is vertical with the axis of input shaft.Second output shaft 8 and main shaft be two separation and
Orthogonal axis is provided with bevel gear structure between the two, so as to be able to drive the rotation of the second output shaft 8 when main axis.
Bevel gear structure includes two mutually identical bevel gears, and one of bevel gear is set on main shaft, another is set to the
End of two output shafts 8 close to main shaft one end.Above-mentioned 7 structure of gear-box enables gear-box 7 in the feelings using a motor
Under condition, while driving wheel 2 and wobble component being driven to work.
Further, in the present embodiment, wobble component includes sliding rack 14 and the cam set being set to inside shell 1
Part, driven wheel 3 are rotatably dispose on sliding rack 14, and sliding rack 14 can be followed to move together.Second output shaft 8 and cam pack
Connection, for driving cam pack, cam pack is able to drive sliding rack 14 and moves back and forth along the axial direction of driven wheel 3.
Driven wheel 3 is rotatably dispose on sliding rack 14, and cam pack is able to drive sliding rack 14 along the axial direction side of driven wheel 3
To reciprocating motion.When conduit delivers in the blood vessels, the blood vessel of fork can be encountered, but conduit itself does not have the ability of steering, therefore
And need to rotate by making conduit, so that conduit is able to enter within the blood vessel of fork.In the present invention, driving wheel 2 and driven wheel 3
After conduit is clamped, sliding rack 14 and cam pack cooperate, and drive driven wheel 3 to move back and forth along axis, due to actively
Wheel 2 will not be swung, and driven wheel 3 can generate frictional force to conduit, this frictional force can be such that conduit rotates when swinging.Most
It is enabled the duct within the blood vessel by being rotated into figure fork eventually.
Further, in the present embodiment, 14 bottom of sliding rack be equipped with guidance set, the guide direction of guidance set with from
The axis of driving wheel 3 is parallel.Specifically, guidance set includes slideway 12 and sliding block 13, slideway 12 is set on the inner wall of shell 1,
Sliding block 13 is set on slideway 12, and is fixedly connected with the bottom of sliding rack 14, the glide direction of sliding block 13 and the axis of driven wheel 3
Line is parallel.Slideway 12 and sliding block 13 can play guiding role to sliding rack 14, prevent sliding rack 14 to be detached from when swinging default
Track influences the delivering effect of conduit.
Further, in the present embodiment, cam pack includes cam 10 and support base 9, and cam 10 is rotatably dispose in branch
It supports on seat 9.Second output shaft 8 is connect with the axle center of cam 10, and when the second output shaft 8 rotates, band moving cam 10 is rotated together.It is sliding
Moving frame 14 is equipped with the top pillar 11 abutted with cam pack, the end of top pillar 11 and the curved surface of cam 10 close to the side of cam pack
It abuts together, so that cam 10 is pushed when rotating and withstand to drive sliding rack 14 mobile.Side far from cam pack is set
Flexible part.One end of elastic component is connect with sliding rack 14, and the other end is abutted with the inner wall of shell 1.When cam 10 will be withstood
It moves to top, elastic component can apply one towards 10 direction screen resilience of cam to sliding rack 14, make sliding rack 14 will not be
Original place can not be returned to when moving to distalmost end.
Further, in the present embodiment, top pillar 11 is equipped with idler wheel close to cam pack one end, and idler wheel is supported with cam pack
It connects.Keep cam 10 more smooth when pushing top pillar 11, promotes fluency when driven wheel 3 is swung.
