Abstract
The utility model discloses a rotary-operated high electrode cardiac catheter, which is composed of a catheter, conducting wires and an operation handle. A relative soft flexible catheter is arranged on one end of the catheter, and the other end of the catheter is connected to the front end of the operation handle, and the conducting wires are arranged in the operating handle and the catheter. An adjusting mechanism is installed on the operation handle, and the adjusting mechanism comprises a rotating shaft and the circular disc which is positioned on the rotating shaft, and the edge of the rotating shaft has a spline and is tied with a steel wire; the position fixing tooth which is cooperated with the spline is fast pressed in the spline which is positioned on the edge of the rotating shaft by a spring and adjusting screws. The other end of the steel wire is welded on the relative soft flexible catheter to act the function that the relative soft flexible catheter is positioned after be bent by pulling the steel wire by a rotary circular disc.
Description
This utility model relates to a kind of accessory of medical apparatus and instruments, is the disappear accessory of turbid instrument of radio frequency.
Existing be used for radio frequency the large electrode operated on the turbid instrument turbid cardiac catheter that disappears that disappears and form employing syringe construction and plug-type regulative mode by conduit, lead and operating handle.Thisly disappear that turbid cardiac catheter degree of regulation is poor, the push-and-pull vibration is big, positioning time is long, accuracy is low.
The purpose of this utility model provides the turbid cardiac catheter that disappears of a kind of large electrode operated that rotates regulative mode, and its degree of regulation height, vibration be little, make short, accurate performance height positioning time.
The purpose of this utility model is achieved in that it is made of conduit, lead and operating handle, and the top of conduit is connected to the operating handle front end for softer flexible conduit, the other end.Lead passes in operating handle and the conduit, links to each other with electrode on the softer flexible conduit.Governor motion is installed on the operating handle, and governor motion includes the disk in rotating shaft and the rotating shaft, and there is teeth groove at the rotating shaft edge, and the positioning tooth that matches with teeth groove is pressed in the teeth groove at rotating shaft edge by spring and adjustment screw.Around being that steel wire is arranged, the other end of steel wire is welded on the electrode of the softer flexible conduit in conduit front portion in the rotating shaft.
Below in conjunction with drawings and Examples, structure of the present utility model is further described in detail.
Accompanying drawing is cutaway view of the present utility model.
Referring to accompanying drawing, this utility model mainly includes conduit 3, lead 14, operating handle 5 and governor motion 7.Conduit is a polyethylene containing metal powder conduit, and an end is softer flexible conduit 2, and the other end inserts the front end of operating handle 5, and fastening by pyrocondensation conduit 4.Operating handle is made hollow garden column type shape with nylon.Lead 14 places in operating handle and the conduit, and outfan links to each other with gold-plated electrode 1 on the softer flexible conduit 2, and input passes from the hole slot 12 of operating handle afterbody, links to each other by plug 13 and the radio frequency turbid instrument that disappears.On the governor motion 7 fitting operation handles 5.Governor motion is by the disk in rotating shaft 15 and the rotating shaft 11, and adjustment screw 9 constitutes.Rotating shaft 15 edges are processed with teeth groove 16 and the binding in wire 6 in the rotating shaft, and the positioning tooth 8 that matches with teeth groove 16 is by spring 10 with adjust screw 9 positioning tooth is pressed abd fixed in the teeth groove at rotating shaft edge.Steel wire 6 other ends are welded on the gold-plated electrode on the softer flexible conduit via in operating handle 5 and the conduit 3.The leading portion and the end of softer flexible conduit are provided with gold-plated electrode, the gold-plated electrode of softer flexible conduit leading portion in the form of a ring and discontinuous distribute.During operation, rotary disk 11 drives rotating shaft 15 and makes the steel wire rotation, and the softer flexible conduit 2 of steel wire pulling bends to desired location.Locate mode is: regulate adjustment screw 9 pressure of spring 10 on positioning tooth 8 can not slided for the operator unclamps rotation disc 11 back rotating disks 11.And the operator gives certain power rotation, and rotating disk 11 can overcome the pressure of positioning tooth 8 and freely rotate.
Outstanding effect of the present utility model is: adopt the rotation regulative mode, make simple to operate, the operating time short, regulate accurately.
Claims (2)
1, the turbid cardiac catheter that disappears of a kind of rotatable operated large electrode, by conduit 3, lead 14, operating handle 5 constitutes, operating handle 5 usefulness nylon are made hollow column type shape, conduit 3 is a polyethylene containing metal powder conduit, the top of conduit is softer flexible conduit 2, the other end inserts operating handle 5 front ends, and it is fastening by the pyrocondensation conduit, lead places in operating handle and the conduit, outfan links to each other with gold-plated electrode on the softer flexible conduit, input passes by plug 13 and the radio frequency turbid instrument that disappears from operating handle afterbody hole slot 12 and links to each other, it is characterized in that being equipped with on the operating handle 5 governor motion 7, governor motion includes rotating shaft, on the axle disk is arranged, and the rotating shaft edge is processed with teeth groove 16 and around being that steel wire 6 is arranged, what cooperate with teeth groove is a positioning tooth 8, positioning tooth is pressed in the teeth groove at rotating shaft edge by spring 10 and adjustment screw 9, and the other end of its steel wire is welded on the gold-plated electrode 1 of softer flexible conduit via in operating handle and the conduit.
2, according to the turbid cardiac catheter that disappears of the said rotary operation type large electrode of claim 1, it is characterized in that the leading portion of softer flexible conduit and end are provided with gold-plated electrode, the gold-plated electrode of leading portion in the form of a ring and discontinuous distribute.
