Abstract
The utility model patent discloses a kind of two-tube sacculus of expansion, and in particular to the technical field of Medical Devices.A kind of two-tube sacculus of expansion, including conduit and balloon body, pressurizing channel is equipped in the conduit, the balloon body is located at the distal end of conduit, it is linked with bifurcated sacculus on the balloon body, the guiding wire for adjusting bifurcated sacculus angle is additionally provided in the conduit.Existing single saccule conduit is overcome using technical solutions of the utility model and is unable to satisfy the problem of expanding to blood vessels adjacent, can be used in cardiovascular blood vessel dilatation operation.
Description
Technical field
The utility model relates to the technical field of Medical Devices, in particular to a kind of two-tube sacculus of expansion.
Background technique
According to the statistics of the World Health Organization, heart disease chronic diseases have become the most important cause of death of the mankind, account for annual dead
Dying total number of persons is more than 60%, wherein especially in the majority with patients with coronary heart disease.Angioplasty (PCI) is then effectively to treat all kinds of blood vessel diseases
The method of disease expands narrow diseased region by percutaneous puncture patient peripheral arterial insertion foley's tube to lesion vessels,
A kind of minimal invasive techniques for dredging lesion vessels.
Sacculus dilating catheter by distal end there is the sacculus of expanding ability and proximal end pipeline section to form.When sacculus dilating catheter
When balloon portion pushes to lesion, balloon dilatation is made by fluid pressure, so that lesion vessels are open-minded, restoration of blood flow is normal,
Operation terminates, then pumpback liquid sacculus pressure release takes out conduit from patient body's blood vessel.
Single saccule expansion pipe is generally adopted by current operation, if blood vessels adjacent needs to expand, then using two
Single saccule conduit is performed the operation, that is, increases the difficulty of operation, also increases the wound to patient.
Utility model content
The utility model is intended to provide a kind of two-tube sacculus of expansion, is unable to satisfy with solving existing single saccule conduit to phase
The problem of adjacent blood vessel is expanded.
In order to achieve the above object, the base case of the utility model is as follows: a kind of two-tube sacculus of expansion, including conduit and
Balloon body, the conduit is interior to be equipped with pressurizing channel, and the balloon body is located at the distal end of conduit, connection on the balloon body
There is bifurcated sacculus, the guiding wire for adjusting bifurcated sacculus angle is additionally provided in the conduit.
The principle and effect of base case: when being treated using this programme to patient, by guiding wire by sacculus sheet
Body and bifurcated sacculus are separately directed to the lesion of blood vessels adjacent, are able to rotate bifurcated sacculus by guiding wire, so as to divide
Fork sacculus accurately send the effect that treatment is improved to the lesion of blood vessels adjacent.Then by inflator to pressurizing channel into
Row pressurising, so that balloon body bulges to the height of setting, due to balloon body and bifurcated sacculus connection, therefore bifurcated sacculus energy
It bulges simultaneously, so that two adjacent vascular openings so that the blood vessel of blocking restores to normal caliber, and then are combined other
Drug treats lesion.Expansion while this programme is realized by the bifurcated sacculus on balloon body to blood vessels adjacent
, and only need to introduce a conduit, to reduce the difficulty of operation and the wound to patient.
Further, bellows is connected between the bifurcated sacculus and balloon body.
Bifurcated sacculus can be extended in the course of surgery by bellows, to enhance the effect of bifurcated sacculus in this programme
Range improves the applicability of the application.
Further, the balloon body is equipped with window and miniature electron mirror for visable indicia, the electronics
Mirror is fixed on guiding wire.
By window and electron mirror convenient for the lesion situation of observation and label vascular, greatly improve treatment efficiency and
Effect.
Further, the surface of the balloon body and bifurcated sacculus is coated with taxol drug layer.
Vascular endothelial cell can be effectively protected by taxol drug layer, reduce the injury to human body.
Detailed description of the invention
Fig. 1 is a kind of main view expanded when two-tube sacculus is closed of the utility model.
Specific embodiment
The utility model is described in further detail below by specific embodiment:
Appended drawing reference in Figure of description includes: conduit 1, balloon body 2, bifurcated sacculus 3, guiding wire 4, bellows
5, window 6.
Embodiment is substantially as shown in Fig. 1: a kind of two-tube sacculus of expansion, including conduit 1 and balloon body 2, opens in conduit 1
There is pressurizing channel, balloon body 2 is located at the distal end of conduit 1, bifurcated sacculus 3, bifurcated sacculus 3 and ball are linked on balloon body 2
It is connected with bellows 5 between capsule ontology 2, the sphere of action of bifurcated sacculus 3 can be extended by bellows 5, enhance this programme
Applicability.The guiding wire 4 for adjusting 3 angle of bifurcated sacculus is additionally provided in conduit 1, guiding wire 4 is slidably connected at pressurising
In channel.It is installed on balloon body 2 there are two the window 6 and miniature electron mirror for being used for visable indicia, two windows 6 distinguish position
In the distal end of balloon body 2 and bifurcated sacculus 3, by window 6 and miniature electron mirror convenient for observation and label, miniature electronics
Mirror is mounted in pressurizing channel；The surface of balloon body 2 and bifurcated sacculus 3 is coated with taxol drug layer, passes through taxol drug
Vascular endothelial cell can be effectively protected in layer, reduce the injury to human body.
In the present embodiment, when being treated using the two-tube sacculus of this programme to patient, by guiding wire 4 by sacculus sheet
Body 2 and bifurcated sacculus 3 are separately directed to the lesion of blood vessels adjacent, if the curtailment of bifurcated sacculus 3 is to reach lesion, energy
Bellows 5 is affected to stretch by guiding wire 4, so that bifurcated sacculus 3 reaches lesion.Then by inflator to pressurising
Channel carries out pressurising, so that balloon body 2 and bifurcated sacculus 3 bulging to the height of setting simultaneously, thus by adjacent two
Blood vessel struts simultaneously, so that the blood vessel of blocking restores to normal caliber, and then treats in conjunction with other drugs to lesion.
In the course of surgery, the case where if desired observing lesion, the case where by means of miniature electron mirror and window 6 to lesion into
Row observation and label, to improve the efficiency and accuracy of operation.The application is realized by bifurcated sacculus 3 to blood vessels adjacent
While expand, and only need to introduce a conduit 1, to reduce the difficulty of operation and the wound to patient.
The above are merely the embodiments of the present invention, the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It should be pointed out that for those skilled in the art, under the premise of not departing from the utility model structure, also
Several modifications and improvements can be made, these also should be considered as the protection scope of the utility model, these all will not influence this reality
With the effect and patent practicability of novel implementation.This application claims protection scope should be with the content of its claim
Standard, the records such as specific embodiment in specification can be used for explaining the content of claim.
