Abstract
The utility model relates to a medical appliance, and particularly relates to a cardiovascular expansion device. The cardiovascular expansion device comprises an expansion tube. The cardiovascular expansion device is characterized in that the expansion tube is a helical tube formed by a filament in a spiral winding manner; a support rod is arranged inside an inner cavity of the helical tube; a fixed fork is arranged at the front end of the support rod; a positioning hole is arranged at the middle section of the support rod; and two ends of the filament are respectively inserted into the fixed fork and the positioning hole. The cardiovascular expansion device is small in diameter when not being embedded, thereby being convenient to carry out embedding operation; the diameter automatically expands after the cardiovascular expansion device is embedded; and the cardiovascular expansion device is simple in structure, convenient to operate, and wide in application range.
Description
Technical field
This utility model relates to a kind of medical apparatus, is a kind of cardiovascular expansion device specifically.
Background technology
At present, cardiovascular expansion operation commonly used is mainly mounting bracket or sacculus, and because the cardiovascular pipeline is thinner, in operation process, operation is pretty troublesome.The installation of support and the adjustment of position all will spend plenty of time and energy, bring difficulty and risk to operation.Chinese patent 2010202319042 discloses a kind of " cardiovascular expansion device " network has been arranged in a guide wire in advance, a tube core also is installed in guide wire simultaneously, during operation, first with the guide wire implantable intravascular, the recycling tube core is released network.This " cardiovascular expansion device " is although can simplify to a certain extent operation technique, improve the accuracy that network puts in place, but due to the diameter of the guide wire diameter greater than network, its scope of application is restricted, and sometimes also can increase the difficulty of operation.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, cardiovascular expansion device of having wide range of applications.
In order to reach above purpose, this utility model adopts following technical scheme: this cardiovascular expansion device comprises convergent divergent channel, it is characterized in that: described convergent divergent channel is to be wound around by single thread spiral the serpentine pipe that forms, be provided with support bar in the inner chamber of described serpentine pipe, the front end of described support bar is provided with fixation fork, the stage casing of support bar is provided with locating hole, and the two ends of monofilament are inserted into respectively in fixation fork and locating hole.
The two ends of described monofilament are respectively arranged with draw-in groove.
The beneficial effects of the utility model are: the diameter of this cardiovascular expansion device when not implanting is less, facilitates implant procedure, and after implanting, its diameter is expanded automatically, and it is simple in structure, easy to operate, have wide range of applications.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the structural representation of monofilament end.
The specific embodiment
As shown in Figure 1, cardiovascular expansion device described in the utility model comprises convergent divergent channel, described convergent divergent channel is the serpentine pipe that is formed by monofilament 1 spiral winding, be provided with support bar 2 in the inner chamber of described serpentine pipe, the front end of described support bar 2 is provided with fixation fork 3, the stage casing of support bar 2 is provided with locating hole 4, and the two ends of monofilament 1 are inserted into respectively in fixation fork 3 and locating hole 4.
As shown in Figure 2, the two ends of described monofilament 1 are respectively arranged with draw-in groove 5.The cross section of described monofilament 1 can make circle, ellipse or square.The cross section of support bar 2 can make circle, ellipse or square.
