Network is released by core.This " cardiovascular expansion device ", although operation technique can be simplified to a certain extent, improves net
The degree of accuracy that shape support puts in place, but because guide wire is with diameter greater than the diameter of network, its scope of application is restricted, and has
When also can increase the difficulty of operation；Another Chinese patent 2013200482005 discloses one kind《Cardiovascular expansion device》, its
The helix tube type expander being wound using single thread spiral, and it is provided with support bar in the inner chamber of helix tube, in support bar
Front end be provided with fixation fork, the stage casing of support bar is provided with location hole, and monofilament is wound around on support bar, the two of monofilament
End is inserted in fixation fork and location hole respectively, after putting blood vessel into, unclamps the two ends of monofilament, extracts support bar, filament diameter out
Automatically expand, play the effect of expansion and support blood vessels wall, its structure is simple and convenient to operate, has wide range of applications.But due to it
Support bar is the fixed structure of integral type, installs and the operation at release monofilament two ends is extremely difficult, prop up extracting out on support bar
Easily the monofilament of half release conditions is brought out during strut, cause operative failure.
Content of the invention
The purpose of this utility model is a kind of special plant of the spiral vessel dilator providing structure to be simple and convenient to operate
Enter operation tool.
In order to reach object above, the utility model is adopted the following technical scheme that：This spiral vessel dilator bag
Include the expander body being coiled to form by column single thread spiral, the upper and lower both sides of described monofilament are symmetrically arranged with draw-in groove, described card
The section of groove is isosceles triangle, and the cylindrical helical body that draw-in groove is formed is coaxial with meristogenetic cylindrical helical body.
Described monofilament is cylindrical structure, and the line between the bottom of two draw-in grooves and the monofilament center of circle is in 150 ° 180 ° folders
Angle.
For the special implant surgery instrument of spiral vessel dilator as mentioned above, including handle, plug-in mounting in the handle
The push rod being axially movable, the rear end of described push rod is provided with pressing plate, and described push rod is set with spiral chuck, described screw clamp
Set is that special-shaped monofilament is upper and lower by the helical structure of special-shaped monofilament helical coil, the rectangular cross-section of described special-shaped monofilament
Two sides are symmetrically arranged with clamping spiral and lower clamping spiral, and described upper clamping spiral and lower clamping spiral are cross sectional shapes
Join the triangle spiral fin of draw-in groove, the axis of described upper clamping spiral and lower clamping spiral is set with the diameter parallel of spiral chuck
Put, one end of special-shaped monofilament is fixedly connected on the front end of push rod, and the other end of special-shaped monofilament is fixedly connected on handle.
Axially arranged keyway is provided with the inwall of described handle, described push rod is provided with the flower mating this keyway
Key.
The beneficial effects of the utility model are：Screw clamp set is clamped using the upper clamping spiral of both sides and lower clamping spiral
So as to the state that is in compression, tightens, caliber is less, facilitates the operation of implantable intravascular for equally spiral-shaped vessel dilator,
Pass through push rod tensile coil chuck after implantation, can easily discharge expander again, this instrument is taken out, its structure letter
Single, easy to operate, have wide range of applications.
Brief description
Fig. 1 is the structural representation of an embodiment of the spiral vessel dilator of the utility model.
Fig. 2 is the structural representation of special implant surgery instrument.
Fig. 3 is the structural representation of the operation tool of clamping vessel dilator.
Fig. 4 is the cross section view of special-shaped monofilament.
Specific embodiment
As shown in figure 1, spiral vessel dilator described in the utility model is included by column monofilament 8 coiled coil
Expander body, the upper and lower both sides of described monofilament 8 are symmetrically arranged with draw-in groove 81,82, and the section of described draw-in groove 81,82 is isosceles
Triangle, the cylindrical helical body that draw-in groove 81,82 is formed is coaxial with the cylindrical helical body that monofilament 8 is formed.And the axle of draw-in groove 81,82
Line and the diameter parallel of monofilament 8.
Described monofilament 8 is cylindrical structure, and the line between the bottom of two draw-in grooves 81,82 and monofilament 8 center of circle is in
150 ° of 180 ° of angles.
As shown in Fig. 2 for the special implant surgery instrument of spiral vessel dilator as mentioned above, including handle 1, inserting
It is contained in the push rod 2 be axially movable in handle 1, the rear end of described push rod 2 is provided with pressing plate 3, handle 1 is column structure, presses
Pressing plate 3, push rod 2 can slide axially in handle 1.Spiral chuck 4 is set with described push rod 2, described spiral chuck 4 be by
The helical structure of special-shaped monofilament helical coil, the material of spiral chuck 4 adopts resilient plastics, stainless steel etc. to make
Become.The rectangular cross-section of described special-shaped monofilament, the upper and lower two sides of special-shaped monofilament are symmetrically arranged with clamping spiral 5 and lower clamping
Spiral 6, described upper clamping spiral 5 and lower clamping spiral 6 are the triangle spiral fins that cross sectional shape mates draw-in groove 81,82, institute
State clamping spiral 5 and the lower axis of clamping spiral 6 is arranged with the diameter parallel of spiral chuck 4, one end of special-shaped monofilament is fixed
It is connected to the front end of push rod 2, the other end of special-shaped monofilament is fixedly connected on handle 1.
In addition, axially arranged keyway is provided with the inwall of described handle 1, described push rod 2 is provided with this key of coupling
The spline 51 of groove.So can only be moved axially by keyway restriction push rod 2 and can not rotate, simultaneously can also be by rationally
