Technical field
The present invention relates to the field of medical instrument technology, more specifically, it relates to which a kind of antisitic defect medical vein blood vessel expands
Prop.
Background technique
Internal arteriovenous fistula is one of surgical operation, is mainly used for hemodialysis.Arteriovenous internal fistula formation is a kind of blood vessel
Forearm is made a suture close to the artery of wrist and neighbouring vein by identical minor operation, makes to flow in the vein after coincideing
Arterial blood is moved, an internal arteriovenous fistula is formed.The blood vessel of internal arteriovenous fistula can provide sufficient blood for hemodialysis,
It is provided safeguard for the adequacy of dialysis treatment.
Currently, vascular conditions difference becomes one of the problem of manufacture internal fistula.Forearm Autogenous arteriovenous internal fistula is because wound is small, operation
Simply, the low advantage of the death rate becomes first choice.As far as possible protect distal vessels and improve success rate of operation be save it is limited itself
Blood vessel necessary condition, the standard of existing vein efferent tract are that internal arteriovenous fistula lumen diameter is more than or equal to 2.5mm, and vein diameter is small
In 2mm.During the patient to vein internal diameter less than 2mm carries out internal fistula art, vascular bundles arm is done frequently with ureteral catheter
Expansion expands blood vessel diameter, to achieve the purpose that improve success rate of operation.
But during ureteral catheter expands blood vessel, blood vessel is often because suddenly by biggish expansionary force
And damaged and vessel inner blood constantly squeezes blood vessel with protruding into for ureteral catheter, causes vasculature part inner wall damaged.Cause

Outer wall is equipped with the punching hole 14 being connected to injection canal 13, and each second level expands body 12 and is correspondingly arranged at least one punching hole 14.
In the present embodiment, each second level expansion body 12 is correspondingly arranged on a punching hole 14.Taper expand body 11 free end protrude into
It expands in blood vessel, taper expands body 11 and tentatively expanded to blood vessel to be expanded；Meanwhile spaced second level expands body 12 and treats expansion
Blood vessel intermittence quadratic extension, reduce blood vessel to be expanded because suddenly by biggish expansionary force due to damaged situation occurs.?
During treating expansion of veins blood vessel dilatation, by syringe 2, into injection canal 13, injecting heparin salt water, heparin saline are passed through
The hydraulic pressure that punching hole 14 flows into intravascular generation expands vein blood vessel to be expanded, reduces blood vessel to be expanded in process of expansion
Frictional dissipation；Meanwhile the heparin saline diffused in blood vessel to be expanded can prevent blood clotting at generation the case where thrombus.
As shown in Fig. 2, syringe 2 and cylindricality expand the end grafting of body 1, so that syringe 2 absorbs heparin saline operation side
Just.
As shown in Figures 1 and 2, it is to expand the ellipsoid that 11 outer wall of body is bonded with taper that second level, which expands body 12,.Using ellipsoid, make
It obtains second level expansion body 12 to expand blood vessel to be expanded since side, enhances second level and expand the reliability that body 12 uses.
As shown in Figure 2 and Figure 3, the outlet end of punching hole 14 is located at corresponding second level and expands on body 12, convenient for by heparin saline
The expansion effect that expansion effect expands body 12 with second level is overlapped, and improves the expansion effect of vein blood vessel expander.
As shown in Figure 2 and Figure 3, the outlet diameter of punching hole 14 is greater than inlet diameter, convenient for slowing down heparin in punching hole 14
Salt water goes out pressure.
As shown in Figure 2 and Figure 3, the outbound course setting at an acute angle of the pressing direction Yu injection canal 13 of punching hole 14, just
It is expanded in unexpanded section of blood vessel to be expanded.
As shown in Fig. 2, the length that taper expands body 11 is 5-8cm, the length that cylindricality expands body 1 is 40-45cm.In the present embodiment
In, taper expand body 1111 length be 8cm, cylindricality expand body 11 length be 40cm so that vein blood vessel to be expanded expansion after at
Type is stablized.
As shown in Fig. 2, the maximum gauge that taper expands body 11 is greater than the diameter that cylindricality expands body 1.Cylindricality expand body 1 diameter be
Any one in 1.5mm, 1.8mm, 2.0mm, 2.2mm, to adapt to the demand of different blood vessel size.
As shown in Fig. 2, syringe 2 includes injection tube 21, injecting cavity 22 is equipped in injection tube 21, injecting cavity 22 is flexibly connected
There is sealing piston 24,21 end of injection tube is equipped with the injection handle 23 being fixedly connected with sealing piston 24.It is stored in injecting cavity 22
There is heparin saline.Injection canal 13 is connected to setting with injecting cavity 22, so that the implant operation of heparin saline is convenient.
As shown in Figure 1, in the present embodiment, cylindricality expands body 1, taper expands body 11 and second level expands body 12 by flexible macromolecule
Material is made, and enables vein blood vessel expander to comply with vein blood vessel trend and is expanded.
Working principle: protruding into blood vessel to be expanded in the free end that taper expands body 11, and taper expands body 11 to blood vessel to be expanded
Tentatively expanded；Meanwhile spaced second level expands body 12 to blood vessel intermittence quadratic extension to be expanded, reduces blood to be expanded
Pipe because suddenly by biggish expansionary force due to damaged situation occurs.During treating expansion of veins blood vessel dilatation, pass through
The injecting heparin salt water into injection canal 13 of syringe 2, the hydraulic pressure that the stamped hole 14 of heparin saline flows into intravascular generation will be to
Expansion of veins blood vessel dilatation reduces frictional dissipation of the blood vessel to be expanded in process of expansion；Meanwhile it diffusing in blood vessel to be expanded
Heparin saline blood clotting can be prevented at generation the case where thrombus.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
