Specific embodiment
It is right below in conjunction with the accompanying drawings in order to which those skilled in the art is made to be better understood when technical scheme of the present invention
Its specific embodiment is described in detail：
It please refers to Fig.1 to Fig. 5, highly preferred embodiment of the present invention, a kind of controllable curved conductor is led including outer conductor 1, internal layer
Pipe 2, the first handle 3 with through-hole and the second handle with through-hole 4.
Inner conductor 2 and outer conductor 1 are sequentially coaxially set from the inside to the outside, and the head end of inner conductor 2 and outer conductor 1
Head end be connected, the tail end of inner conductor 2 extends to the outside of outer conductor 1.
Offer several grooves 11 in the outside wall surface on the head of outer conductor 1 evenly and at intervals, in several grooves, first
Groove is adjacent with the head end of outer conductor 1, and the distance between first of groove and the head end of outer conductor 1 are 2mm~6mm；
It is 2mm~4mm the distance between per two adjacent grooves 11.
Inner conductor 2 is made of composite material, and the internal face of inner conductor 2 is provided with one layer of mesh grid, and mesh grid is adopted
Use helix.
The head of first handle 3 is socketed in the tail portion of outer conductor 1, and the tail portion of first handle 3 offers handle card slot 31；
The internal face of first handle 3 is provided with an annular convex platform 32, and annular convex platform 32 is located at the slot bottom of handle card slot 31, outer conductor
1 tail end and annular convex platform 32 are inconsistent.
The head of second handle 4 is socketed in the tail portion of inner conductor 2, and the head of second handle 4 is plugged on handle card slot
In 31；Its axial direction of the outside wall surface upper edge on the head of second handle 4 is provided with a convex ribs 41, is set on the internal face of handle card slot 31
The convex ribs card slot 33 being adapted with convex ribs 41 is equipped with, convex ribs 41 are connected in convex ribs card slot 33, and convex ribs 41 and convex ribs card slot 33
It is installed by clearance fit, it can be to avoid the mutually rotation of generation between first handle 3 and second handle 4.
The internal face of second handle 4 is provided with an annular step surface, and the tail end of inner conductor 2 offsets with annular step surface
It touches.The tail end of second handle 4 is provided with female Luer connector 43.
It please refers to Fig.1 again and Fig. 6, controllable curved conductor of the invention when in use, passes through two layers of conduit and two handle realities
The controlled deflection of existing conduit, concrete operating principle are as follows：The original state of controllable curved conductor is straight state, first handle 3 and the
The position being in contact of two handles 4 is convex ribs card slot 33 and convex ribs 41, and convex ribs 41 are slided along convex ribs card slot 33.By second handle 4
Certain distance is pushed forward, and 3 position of first handle remains stationary as, and the junction Forward of two handles, i.e. convex ribs 41 are along convex ribs card
Slot 33 moves forward, 2 stress of inner conductor, it is desirable to bend, but because the head end of outer conductor 1 and the head end of inner conductor 2 connect
Together, and outer conductor 1 only on head there are several grooves 11, the conduit at other positions is thus entire there is no gap
Controllable curved conductor can start to be bent at groove 11, and conduit can be bent upwards at this time, the gap enlargement of channel bottom, with second
The back-and-forth motion of 4 position of handle, the bending angle of conduit can change therewith.Such as during the forward movement of second handle 4, entirely
Controllable curved conductor starts to be bent upwards.As the increase bending angle of the forward movement distance of second handle 4 also becomes larger；It is first-hand
3 position of handle remains stationary as, and second handle 4 moves backward, and entire controllable curved conductor gradually returns to original state.
The controllable curved conductor of the present invention, workflow are：
Step 1：Conduit is in straight state, and two handles are linked together by convex ribs 41 and convex ribs card slot 33；
Step 2：3 position of holding first handle is constant, and second handle 4 moves forward, and conduit starts to be bent upwards.Bending angle
Degree changes with the displacement distance of second handle 4；
Step 3：First handle 3 remains stationary as, and second handle 4 moves backward, and conduit gradually returns to original state.
The controllable curved conductor of the present invention, the head of outer conductor 1 are provided with equidistant groove 11, and inner conductor 2 is because of second-hand
Handle 4 moves and stress, but two layers of conduit connects together in head end, because there is a groove on the head of outer conductor, during conduit stress
Channel bottom is expanded, and then conduit is made to bend, and bending angle changes with the distance between two handles, i.e., bending angle is with the
Distance between the slot bottom of the head end of two handles 4 and the handle card slot 31 of first handle 3 and changing allows conduit flexibly to pass through
Blood vessel or other lacunas, smoothly reach lesion.
In conclusion the controllable curved conductor of the present invention, bending angle can change with the distance between two handles, make conduit can
Flexibly to pass through blood vessel or other lacunas, lesion is smoothly reached.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will be all fallen in the range of claims of the present invention.
