The helical structure that rotation shape is coiled to form, the section of the special-shaped monofilament is circle, and the upper and lower two sides of special-shaped monofilament are symmetrically arranged with
Upper clamping spiral and lower clamping spiral, the upper clamping spiral and lower clamping spiral are the triangle spiral shells of cross sectional shape matching neck
Fin is revolved, the diameter parallel of the axis and spiral chuck of the upper clamping spiral and lower clamping spiral is set, and the one of special-shaped monofilament
End is fixedly connected on the front end of push rod, and the other end of special-shaped monofilament is fixedly connected on handle；Form the monofilament of expander body
It is clamped in the gap between screw for the special-shaped monofilament for forming spiral chuck；The outer wall of the handle is fixedly connected with drag hook.
The monofilament is cylindrical structure, and the line between the bottom and the monofilament center of circle of two necks is in 150 ° --- 180 ° of folders
Angle.
Axially arranged keyway is provided with the inwall of the handle, the flower for matching the keyway is provided with the push rod
Key.
The upper and lower two sides of the special-shaped monofilament are symmetrically arranged with recessed deep-slotted chip breaker, the upper clamping spiral and lower folder
Spiral is held to be arranged in deep-slotted chip breaker.
The beneficial effects of the present invention are：Screw clamp set is clamped equally using the upper clamping spiral and lower clamping spiral of both sides
Spiral-shaped vessel dilator, the state compressed, tightened is at, caliber is smaller, facilitates the operation of implantable intravascular, implantation
Later by push rod tensile coil chuck, expander can be easily discharged again, the instrument is taken out, its simple in construction, behaviour
Work is convenient, has wide range of applications.

Embodiment
As shown in figure 1, the clipping vessel dilator assembly of spiral of the present invention include by the coiled coil of column monofilament 8 and
Into expander body and clamping device for clamping expander body, the upper and lower both sides of the monofilament 8 are symmetrically arranged with
Neck 81,82, the section of the neck 81,82 is isosceles triangle, the cylindrical helical body and the shape of monofilament 8 that neck 81,82 is formed
Into cylindrical helical body it is coaxial.And the diameter parallel of the axis of neck 81,82 and monofilament 8.
The monofilament 8 is cylindrical structure, and the line between the bottom and the center of circle of monofilament 8 of two necks 81,82 is in
150 ° --- 180 ° of angles.
As shown in Fig. 2 the clamping device includes handle 1, is inserted into the push rod 2 being axially movable in handle 1, it is described to push away
The rear end of bar 2 is provided with pressing plate 3, and handle 1 is column structure, can be slid axially by dynamic pressure plate 3, push rod 2 in handle 1.Institute
State and spiral chuck 4 is set with push rod 2, the spiral chuck 4 is the helical structure formed by special-shaped monofilament helical coil, spiral shell
The material of rotation chuck 4 is made of flexible plastics, stainless steel etc..The section of the special-shaped monofilament is circular, special-shaped monofilament
Upper and lower two sides are symmetrically arranged with clamping spiral 5 and lower clamping spiral 6, and the upper clamping spiral 5 and lower clamping spiral 6 are
Cross sectional shape matches the axis and spiral shell of the triangle spiral rib of neck 81,82, the upper clamping spiral 5 and lower clamping spiral 6
The diameter parallel for revolving chuck 4 is set.Upper clamping spiral 5 and lower clamping spiral 6 can be set directly at cylinder as shown in Figure 4
Outer surface, can also be as shown in figure 5, be symmetrically arranged with recessed deep-slotted chip breaker 10,11, institute in the upper and lower two sides of special-shaped monofilament
State clamping spiral 5 and lower clamping spiral 6 is arranged in deep-slotted chip breaker 10,11.
One end of special-shaped monofilament is fixedly connected on the front end of push rod 2, and the other end of special-shaped monofilament is fixedly connected on handle 1
On；The outer wall of the handle 1 is fixedly connected with drag hook 9.Drag hook 9 coordinates with pressing plate 3, can be promoted push rod 2 by extruding
Slided in handle 1.
As shown in figure 3, the monofilament 8 for forming expander body is clamped between the spiral for the special-shaped monofilament for forming spiral chuck 4
In gap.Upper clamping spiral 5 and lower clamping spiral 6 are correspondingly embedded in neck 81,82, though monofilament 8 has the elasticity of expansion, by different
The clamping of shape monofilament, it can not depart from.
In addition, being provided with axially arranged keyway on the inwall of the handle 1, it is provided with the push rod 2 and matches the key
The spline 51 of groove.Push rod 2 so, which can be limited, by keyway can only move axially that can not rotate, while can also be by reasonable
The length of keyway is set to limit the scope that push rod 2 moves axially.
As shown in figure 3, in use, the monofilament of spiral vessel dilator is installed on upper clamping spiral 5 and lower clamping spiral shell
Between rotation 6, because the pitch of spiral chuck 4 is less than from --- the distance between i.e. upper clamping spiral 5 and lower clamping spiral 6 ---
The diameter of spiral-expanding device monofilament, upper clamping spiral 5 and lower clamping spiral 6 are embedded in neck 81,82, and now spiral chuck 4 can
It is set not release to clamp expander, can be easily in implantable intravascular.After expander insertion patient's blood vessel, pressing pressure
Plate 3 is expanded by the tensile coil chuck 4 of push rod 2, the spiral shell spacing of spiral chuck 4, and upper clamping spiral 5 and the lower spiral 6 that clamps are from card
Depart from groove 81,82, now i.e. releasable expander, its enlarged-diameter after expander is released, be supported on patient's blood vessel wall
On, the clamping device can now be taken out.
