In order to address this problem, people have adopted conduit and its joystick of various structures, for example conduit and the joystick of disclosed a kind of dual control in U.S. Patent application US2008039918A1, the far-end of this conduit can carry out bending or adjust the diameter of spiral part, wherein diameter crooked and that adjust spiral part is to realize by two control keys on control handle respectively, in actual mechanical process, user need to regulate respectively, is not easy to directly realize with a hands control and the operation of conduit.
It is all minute to be arranged conventionally that there is the control key of controlling seal wire on the conduit joystick of two seal wires existing inside, in use needs finger constantly to do on a large scale and move, and controls different operated keys, causes and uses inconvenience, finger fatiguability.
Summary of the invention
The object of this invention is to provide a kind of controlling conveniently, the curved electrophysiologicalcatheter catheter of dual control simple in structure.
Technical scheme of the present invention is, the curved electrophysiologicalcatheter catheter of a kind of dual control, the first seal wire and the second seal wire that comprise conduit, catheter interior, be used for the handle body of connecting duct and be arranged on push-and-pull control key and the Spin Control key of controlling respectively the first seal wire and the second seal wire on handle body, it is characterized in that: described push-and-pull control key and Spin Control key are engaged on handle body synchronous slide along its length, Spin Control bond energy is enough to rotate with respect to push-and-pull control key.
Preferably, described Spin Control key is arranged on push-and-pull control key, described push-and-pull control key comprises mandrel, is fixed on the control key on mandrel, mandrel can slide with respect to handle body, on mandrel, be useful on the standing part of A/C, in handle body, be useful on the fixture of fixing the first seal wire; Spin Control key is arranged on mandrel, can rotate with respect to mandrel.
Preferably, be fixed with a linkage part on the second seal wire, when Spin Control key rotates with respect to push-and-pull control key, Spin Control key drives this linkage part to move with respect to push-and-pull control key.
Preferably, a described linkage part part is arranged in the chute of mandrel length direction, and another part is positioned at the chute of Spin Control key internal coiling shape, and the second seal wire penetrates catheter interior through the pulley being arranged on mandrel.
Preferably, have a complete or annular groove partly on mandrel, have a screw on Spin Control key, the head of screw is positioned at groove, and restricting rotation control key slides along mandrel.
Preferably, described linkage part is fixed on Spin Control key, and the second seal wire penetrates catheter interior through the pulley being arranged on mandrel.
Preferably, also have a guiding catheter on described linkage part, the second seal wire is inner from locking device, and fixing.
Preferably, described distal end of catheter has two or more bending sections.
The invention has the beneficial effects as follows: the push-and-pull control key on modular catheter and Spin Control key synchronous slide, can be controlled by one hand, promoting push-and-pull control key and Spin Control key can directly be completed by one hand, facilitates user to control and adjust the multiple directions bending of conduit.In part preferred embodiment, fit system between push-and-pull control key and Spin Control key is reasonably set, fixed position with seal wire, the relative motion that can effectively decompose the first seal wire and the second seal wire, avoid being intertwined between the two, and can be so that control key operation is more smooth; In part preferred version, by rational configuration linkage parts, can be so that control key to be more convenient when assembling, the motion of linkage part is more smooth.

Fig. 2 is the schematic diagram of the Spin Control key after cutting open in handle shown in Fig. 1.
Fig. 3 is the cutaway view of handle portion shown in Fig. 1.
Fig. 4 to 7 is embodiment of the curved electrophysiologicalcatheter catheter of dual control of the present invention schematic diagrams under different using states.
The specific embodiment
Specific embodiments of the invention, the handle of the curved electrophysiologicalcatheter catheter of a kind of dual control, as shown in Figure 1, comprise handle body 8, mandrel 9 is arranged in handle body 8, can slide along handle body 8, and control key 1 is fixed on mandrel 9, form push-and-pull control key together with mandrel 9, conduit and push-and-pull control key are fixed together, and the first seal wire is fixed on handle body 8 inside through mandrel 9, when promoting push-and-pull control key, conduit and the first seal wire relative position change, and distal end of catheter can bend, on mandrel 9, there is the annular groove of a section, Spin Control key 2 is arranged on mandrel 9, screw 3 is through Spin Control key 2, the head of screw 3 is positioned at annular groove, for limiting the relative axial position of Spin Control key 2 and push-and-pull control key, do not change, when finger push push-and-pull control key, Spin Control key 2 also can move thereupon, as shown in Figure 2, in Spin Control key 2 inside, there is a spiral groove 11, again as shown in Figure 1, on the second seal wire, be fixed with a linkage part 5, on linkage part 5, have one spiral helicine protruding 12, this projection 12 is positioned at spiral groove 11, on mandrel 9, there is one section of recessed mating surface to coordinate with linkage part 5 inner curve, one end of the second seal wire is fixed on linkage part 5, then by pulley 7 its other ends that are arranged on mandrel 9, penetrate in conduit, and fixing, pulley is by axle 6 installations and mandrel 9, when 2 rotation of Spin Control key, linkage part 5 endwisely slips along mating surface in spiral groove, thereby lead the second guide wire movement, control the far-end of conduit and do bending or other motions.The handle of this structure, adjusts control key convenient, and user indefatigability, and its reasonable in internal structure, move between seal wire smooth and easy, and handle is convenient to assembling assembling.
Preferably, in order to facilitate the location of the second seal wire, can on linkage part 5, increase a locking device 4, allow the second seal wire in locking device 4, and fixing.
5 one kinds of simplified ways of Spin Control key 2 in the above-described embodiments and linkage part, can be fixed on linkage part on Spin Control key 2, during 2 rotation of Spin Control key, directly draw the second seal wire motion, thereby control the bending of conduit.
