Detailed description of the invention
As shown in Figure 1, the clipping vessel dilator assembly of spiral of the present invention includes the dilator body by column monofilament 8 coiled coil and for clamping the clamping device of dilator body, the upper and lower lateral symmetry of described monofilament 8 is provided with draw-in groove 81,82, the cross section of described draw-in groove 81,82 is isosceles triangle, and 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 axis of draw-in groove 81,82 is parallel with the axis of monofilament 8.
Described monofilament 8 is cylindrical structure, and the line between bottom and monofilament 8 center of circle of two draw-in grooves 81,82 is 150 ° of 180 ° of angles.
As in figure 2 it is shown, described clamping device includes handle 1, is inserted in handle 1 push rod 2 being axially movable, the rear end of described push rod 2 is provided with pressing plate 3, and handle 1 is column structure, can slide axially by dynamic pressure plate 3, push rod 2 in handle 1.Being set with spiral chuck 4 on described push rod 2, described spiral chuck 4 is by the helical structure of special-shaped monofilament helical coil, and the material of spiral chuck 4 adopts resilient plastics, rustless steel etc. to make.The cross section of described special-shaped monofilament is circular, 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 that the triangle spiral fin of cross sectional shape coupling draw-in groove 81,82, described upper clamping spiral 5 and the axis of lower clamping spiral 6 be arranged in parallel with the axis of spiral chuck 4.Upper clamping spiral 5 and lower clamping spiral 6 can be set directly at cylindrical outer surface as shown in Figure 4, can also be as shown in Figure 5, be symmetrically arranged with recessed arcuate groove 10,11 in the upper and lower two sides of special-shaped monofilament, described upper clamping spiral 5 and lower clamping spiral 6 are arranged in arcuate groove 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；The outer wall of described handle 1 is fixedly connected with drag hook 9.Drag hook 9 coordinates with pressing plate 3, slides in handle 1 by extruding to be promoted by push rod 2.
As it is shown on figure 3, the monofilament 8 constituting dilator body is clamped in the gap between screw of the special-shaped monofilament constituting spiral chuck 4.Upper clamping spiral 5 and lower clamping spiral 6 are correspondingly embedded in draw-in groove 81,82, though monofilament 8 has the elasticity of expansion, but are subject to the clamping of special-shaped monofilament, it is impossible to depart from.
It addition, the inwall of described handle 1 is provided with axially arranged keyway, described push rod 2 is provided with the spline 51 mating this keyway.So can only being moved axially by keyway restriction push rod 2 and can not rotate, the length that simultaneously can also pass through rationally to arrange keyway limits the scope that push rod 2 moves axially.
As shown in Figure 3, during use, the monofilament of spiral vessel dilator is installed between upper clamping spiral 5 and lower clamping spiral 6, owing to the pitch of spiral chuck 4 is from namely above clamping the diameter less than spiral-expanding device monofilament of the distance between spiral 5 and lower clamping spiral 6, upper clamping spiral 5 and lower clamping spiral 6 embed in draw-in groove 81,82, now spiral chuck 4 can be clamped dilator and makes it to get loose, it is possible to easily in implantable intravascular.After dilator inserts patient's blood vessel, pressing pressing plate 3 is by push rod 2 tensile coil chuck 4, the spiral shell spacing of spiral chuck 4 expands, upper clamping spiral 5 and lower clamping spiral 6 depart from from draw-in groove 81,82, it it is now releasable dilator, dilator be released after its enlarged-diameter, be supported on Blood of Patients tube wall, now this clamping device can be taken out.
