Existing inside has the control key catheter control handle of two seal wire controlling seal wire to be usually all provided separately, and in use needs finger constantly to do and moves on a large scale, control different operated keys, cause and use inconvenience, finger fatiguability.
Summary of the invention
The object of this invention is to provide a kind of manipulation convenient, the simple Double-control bent electrophysiologicalcatheter catheter of structure.
Technical scheme of the present invention is, a kind of Double-control bent electrophysiologicalcatheter catheter, comprise conduit, the first seal wire of catheter interior and the second seal wire, for connecting duct handle body and be arranged on the push-and-pull control key and Spin Control key that handle body control respectively the first seal wire and the second seal wire, it is characterized in that: described push-and-pull control key and Spin Control key to be engaged on handle body synchronous slide along its length, Spin Control bond energy is enough to rotate relative 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, the control key be fixed on mandrel, mandrel can slide relative to handle body, mandrel there is the standing part for A/C, in handle body, having the fixture for fixing the first seal wire; Spin Control key is arranged on mandrel, can rotate relative to mandrel.
Preferably, the second seal wire is fixed with a linkage part, when Spin Control key rotates relative to push-and-pull control key, Spin Control key drives this linkage part to move relative 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 be arranged on mandrel.
Preferably, mandrel has a complete or annular groove partly, and Spin Control key has a screw, and the head of screw is positioned at groove, and restriction Spin 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 be arranged on mandrel.
Preferably, described linkage part also has a guiding catheter, 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, promotion push-and-pull control key and Spin Control key can directly be completed by one hand, and the multiple directions of person's controlling and adjustment conduit easy to use bend.In certain preferred embodiments, fit system between push-and-pull control key and Spin Control key is reasonably set, with the fixed position of seal wire, effectively can decompose the relative motion of the first seal wire and the second seal wire, avoid being intertwined therebetween, and it is more smooth that control key can be made to operate; In part preferred version, by rational configuration linkage parts, control key can be made more convenient when assembling, and the motion of linkage part is more smooth.
