Abstract
The invention discloses a kind of Double-control bent handle, comprise handle body and control push-and-pull control key and the Spin Control key of the first seal wire and the second seal wire respectively, 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.Double-control bent handle push-and-pull control key of the present invention and Spin Control key synchronous slide, can be controlled by one hand, and promoting push-and-pull control key and Spin Control key can directly be completed by one hand, control, easy to use.
Description
Technical field
The present invention relates to the joystick of medical catheter, especially a kind of Double-control bent handle of handled easily.
Background technology
Catheter tube is made up of pliable and tough biocompatible materials usually, such as plastics, comprises polyethylene, polyester or polyamide.Because the physiological structure of human body is complicated, the handle needing handling superior to control conduit, can control conduit accurately arrive different lesions position be have challenging.
In order to address this problem, people have employed the modular catheter of various structures, the conduit of such as a kind of dual control disclosed in U.S. Patent application US2008039918A1 and joystick, the far-end of this conduit can carry out the diameter bending or adjust spiral part, wherein diameter that is bending and adjustment spiral part is realized by two control keys on control handle respectively, in actual mechanical process, user needs to regulate respectively, is not easy to the control and the operation that directly realize conduit with a hands.
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 handle of structure.
Technical scheme of the present invention is, a kind of Double-control bent handle, comprise handle body and control push-and-pull control key and the Spin Control key of the first seal wire and the second seal wire respectively, 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.
Preferably, described push-and-pull control key comprises mandrel, the control key be fixed on mandrel, and mandrel can slide relative to handle body, mandrel has the standing part for A/C, has the fixture for fixing the first seal wire in handle body; 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 locking device inside through the pulley be arranged on mandrel, and fixing.
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 locking device inside through the pulley be arranged on mandrel, and fixing.
The invention has the beneficial effects as follows: push-and-pull control key 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.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the exploded view of the embodiment of Double-control bent handle of the present invention.
Fig. 2 be embodiment illustrated in fig. 1 in cut open after the schematic diagram of Spin Control key.
Fig. 3 is sectional view embodiment illustrated in fig. 1.
Detailed description of the invention
Specific embodiments of the invention, a kind of Double-control bent handle, 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, push-and-pull control key is formed together with mandrel 9, conduit and push-and-pull control key are fixed together, and it is inner that the first seal wire is fixed on handle body 8 through mandrel 9, when promoting push-and-pull control key, conduit and the change of the first seal wire relative position, distal end of catheter can bend, mandrel 9 has 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, relative axial position for limiting Spin Control key 2 and push-and-pull control key does not change, when finger push push-and-pull control key, Spin Control key 2 also can move thereupon, as shown in Figure 2, a spiral groove 11 is had in Spin Control key 2 inside, again as shown in Figure 1, second seal wire is fixed with a linkage part 5, linkage part 5 has one spiral helicine protruding 12, this projection 12 is positioned at spiral groove 11, mandrel 9 there is one section of recessed mating surface coordinate with linkage part 5 inner curve, second seal wire penetrates in locking device 4 by the pulley 7 be arranged on mandrel 9, and it is fixing, pulley 7 is installed with on mandrel 9 by axle 6, when Spin Control key 2 rotates, linkage part 5 slides axially along mating surface in spiral groove, thus lead the second guide wire motion, the far-end controlling conduit does bending or other motions.The handle of this structure, adjustment control key is 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, the conveniently location of the second seal wire, can increase a locking device 4, allow the second seal wire penetrate in locking device 4 on linkage part 5, and fixing.
Spin Control key 2 in the above-described embodiments and linkage part 5 one kinds of simplified ways, can be fixed on Spin Control key 2 by linkage part, when Spin Control key 2 rotates, directly draw the second guide wire motion, thus control the bending of conduit.
