Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Fig. 2 and Fig. 3 is the schematic diagram of different conditions embodiment illustrated in fig. 1.
Fig. 4 is assembly drawing embodiment illustrated in fig. 1.
Detailed description of the invention
Specific embodiments of the invention, as shown in Fig. 12, a kind of three control curved hand grips and use the conduit of this device, comprising:
In this manual, term conduit refers to and comprises conduit (but not limited) and similar medical apparatus and instruments.In FIG, conduit is divided into substantially: electrode 1, far-end 2, catheter tube 3 and control handle (i.e. the grip of propulsion plant, the first push-and-pull key and the second push-and-pull key 5), control handle entirety is used for controlling the relative position of seal wire and catheter tube, thus control the bending of far-end 2 or deflection, or control length and the spiral size of spiral section.
Above-mentioned grip comprises the handle upper cover 2 and handle lower cover 1 combined.At handle upper cover 2 and handle lower cover 1 built with sliding shoe 10, lumen tube 13, wheel 16, lock-screw 19, second push-and-pull key 5, wherein the first push-and-pull key comprises push-and-pull key 6 and Pushpulll locking key 7, first push-and-pull key is enclosed within outside grip, be connected with sliding shoe 10 by pin 71, sliding shoe 10 has the lock-screw 19 for fixing the first traction steel wire 21; First traction fiber 21 is changed direction by wheel 16, wraparound is locked on sliding shoe 10, grip have for passing through and the bar hole allowing pin to slide wherein, Pushpulll locking key 7 there is one or more groove, skewed slot from deep to shallow, coordinates with push-and-pull key 6 inwall salient point, when push-and-pull key 6 rotates, the salient point of push-and-pull key 6 slides from the depths of Pushpulll locking key 7 groove toward superficial part position, reaches locking effect.The push-pull shaft of the second push-and-pull key 5, this push-pull shaft is slidably arranged in lumen tube 13, and on push-pull shaft, cover has the elastic ring 14 for controlling damping.On the rotatable push-pull shaft being arranged on the second push-and-pull key 5 of second traction fiber 15, passed by push-pull shaft inside exactly specifically in this example, be fixed on a rotatable gear 16, this gear 16 is arranged on push-pull shaft can the groove of axial location, and there is part tooth to be exposed at outside push-pull shaft, rotation key 8 inwall engages with gear 16, and driven gear 16 and the second traction fiber 15 rotate, wire 17 tail end being extended to control handle by push-pull shaft inside process too of catheter interior.More preferably, rotation key 8 is coordinated with gear 16 by the rotational lock key 9 being arranged on its inwall, and the tail end band tooth of rotation key 8, turns right when rotation key 8 and pull, the tooth of rotation key 8 tail end and the tooth of rotational lock key 9 can be made to be in engagement, to reach locking object.Rotational lock key 9 is connected with the second push-and-pull key 5 by pin, makes rotational lock key 9 become retainingf key.
The structural principle of the control handle of conduit of the present invention as shown in Figure 4.
Control handle different operating state of the present invention as shown in Figure 1 to Figure 3, Fig. 1 is original state, then regulate by shown in Fig. 2, the right side draws the second push-and-pull key 2, second traction fiber to be tightened up, spiral far-end furthers lopping, driving the second traction fiber to rotate by rotating rotation key again, changing the size of spiral distal end convolutions circle, after completing, can press shown in Fig. 3 and regulate the first push-and-pull key, change the relative position of catheter tube and the first traction fiber thus the bending of control distal end of catheter.
