Supplementary technology scheme of the present invention is as follows:

Preferably, described first fixture is first adjustment screw, and described second fixture is second adjustment screw, and first adjustment screw is parallel with rotating shaft with second adjustment screw, and traction fiber is wrapped on the adjustment screw.

Preferably, described rotary part cooperates by guide rail and guide pillar with grip.

Preferably, on described grip, have and two sections circular-arc guide rails, the guide pillar that cooperates with guide rail is arranged on rotary part.

Preferably, described guide pillar is an adjustment screw.

Preferably, a passage along the grip length direction is arranged on rotary part, this width of channel is arranged to, when rotary part around rotating shaft ± 60 ° of whens rotation, the both sides of passage can not surpass the grip centrage.

Preferably, described rotary part comprises the driving loam cake that is positioned at the grip outside and drives lower cover, and the drive block that is positioned at grip inside, adjustment screw is passed hole, the guide rail on the grip, the hole on the drive block that drives loam cake and is driven the hole that covers down several parts are installed together, between driving loam cake and grip, be provided with elastic seal ring, between driving lower cover and grip, be provided with elastic seal ring.

Preferably, be fixed with regulating handle in the both sides that drive loam cake or driving lower cover.

The invention has the beneficial effects as follows:

1, can control two traction fiber routing motions, the far-end of control conduit bends towards a plurality of directions, operates more flexible;

2, in some preferred embodiments, the design of grip and rotary part meets the human engineering principle, and palm can be held the handle of rotary part fully, in the operating process, the finger, the palm indefatigability, and in the user operating process smooth operation;

3, in some preferred embodiments, grip and rotary part assembly relation are reasonable, make that the structure of whole device is more simple, rationally, are easy to the processing assembling.

Description of drawings

The present invention will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the sketch map of the embodiment of the invention.

Fig. 2 is the assembly drawing of the embodiment of the invention.

Fig. 3 is the cutaway view of the rotating part of the embodiment of the invention.

The specific embodiment

Specific embodiments of the invention, as depicted in figs. 1 and 2, a kind of pair of bending of the hand handle, comprise: conduit (in this manual, the term conduit refers to and comprises conduit and similar medical apparatus and instruments), shown in Fig. 1, conduit is divided into substantially: electrode 5, far-end 4, catheter tube 1, and control handle 2(is the grip and the operating element of propulsion plant), control handle 2 integral body are used for controlling the relative position of traction fiber 6 and catheter tube 1, thereby the bending or the deflection of control far-end 4, the lead 7 of transmission of electric signals or energy passes rotary part 22 in catheter tube 1, arrive the afterbody joint 8 of control handle 2.

The structural principle of the control handle of conduit of the present invention is shown in Fig. 2 and 3.Wherein, grip 2 and the operating element that is rotatably installed in the grip, catheter tube 1 is connected with operating element 2, the traction fiber 6 of catheter interior is connected with operating element, operating element is adjusted the length of traction fiber 6 by rotation, and then the bending of control distal end of catheter 4.Described grip and operating element comprise: the handle lower cover 23 and the handle loam cake 21 that constitute grip 2, the loam cake of driving 19 is arranged and drive lower cover 24 at the handle lower cover 23 and handle loam cake 21 outsides, in the position that drives loam cake 19 and drive between the lower cover 24 one spill spin block 22 is arranged, and this spill spin block 22 is positioned at handle lower cover 23 and handle loam cake 21 inside.On driving loam cake 19 and driving lower cover 24, be respectively equipped with through hole, be used to pass first and second adjustment screw 18, first and second adjustment screw 18 are passed the hole that drives on the loam cake 19 successively, through corresponding groove guide rail on the handle loam cake 21, hole on the spill spin block 22, groove guide rail on the handle lower cover 23, driving hole on the lower cover 24 cooperates with lock-screw 25 several parts is fixed together, on driving, 19 and grip between be provided with elastic seal ring 20, drive between lower cover 24 grips and be provided with elastic seal ring 20.In spill spin block 22 inside one passage is arranged, be used for by lead 7, this width of channel is arranged to, when rotary part around rotating shaft at ± 60 ° or more during the polarizers of big angle scope internal rotation, the both sides of passage can not surpass the grip centrage, can guarantee that like this lead can not scratched.
