Abstract
It the utility model is related to operation on vessels of heart, and in particular to a kind of cardiovascular expansion device.A kind of cardiovascular expansion device, including air bag and intravascular stent, the air bag are olive shape, and this 3~5 grooves are uniformly distributed on the air bag of olive shape, and the thickness of the groove is more than air bag high spot surface thickness；The gasbag outer surface of the olive shape is set with intravascular stent, and the air bag is connected by tracheae with extraneous air pump.The beneficial effects of the utility model are：Support is inflated to intravascular stent using annular air-pocket, airbag design olive shape, it is provided with groove, conveniently make blood circulation, solve the problems, such as that the expansion operation of existing design central vessel can block blood circulation, because not directly improved on air bag, original scaling is not reduced, in blood vessel transport, compared with can also be passed through in thin vessels, reduce operation risk.
Description
Technical field
It the utility model is related to operation on vessels of heart, and in particular to a kind of cardiovascular expansion device.
Background technology
Heart is a hollow flesh sexual organ, positioned at the middle part in thoracic cavity, is divided into left and right two chambers by an interval, each
Chamber is divided into the ventricle two parts in superposed atrium and bottom again.Atrium is collected goes out the heart into heart blood, Ve.Ventricle
Inlet and outlet have a valve, ensure blood one-way flow.Angiocarpy is made up of the heart and blood vessel, blood vessel again include artery,
Vein and capillary.When clinically carrying out painstaking effort enlargement of pipe to patient, majority mounting bracket or ball in patient's angiocarpy
Capsule, but because painstaking effort pipeline is thinner, support or sacculus are manually loaded with regard to relatively difficult, and blood is blocked in process of expansion completely
Liquid is circulated, and intravascular neoplasm attrition crushing can not be completely removed, and work difficulty is added to medical worker.
Comparatively ideal dilating sacculus be well on sacculus, be recognized better than be used for the purpose of any polyethylene balloon,
But sacculus blocks blood circulation completely in process of expansion on well, easily causes the symptoms such as low blood pressure, the loss of consciousness, twitch, to doctor
Business personnel add great work difficulty.
The patent of Patent No. 201521062780.9 discloses a kind of cardiovascular expansion device, it is characterised in that including
Cylindrical outer casing and intravascular stent, the head of the cylindrical outer casing is taper and middle part is cylindrical, the inside of the cylindrical outer casing
Provided with cavity, the head of the taper and the bottom of cylinder are equipped with through hole, and the through hole connects with cavity, the blood vessel
Rack inner wall is provided with annular air-pocket, and the lateral wall of the annular air-pocket is provided with the cylindrical protrusions for preventing that intravascular stent from coming off, institute
Annular air-pocket is stated to be connected with extraneous air pump by tracheae.This patent solves in above-mentioned process of expansion substantially blocks blood to follow completely
Ring, the problem of easily causing low blood pressure, but appoint Shortcomings, and during device reaches focus, smaller easier transport, but by
In the presence of through hole, the scaling of cardiovascular expansion device is caused to be much worse than greatly in the past, when device is not up to focus point just
Occur due to device is excessive and cause be difficult in compared with thin vessels by the problem of, add operation risk.
Utility model content
For the deficiency in structure in the prior art, the utility model provides a kind of cardiovascular expansion device
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of cardiovascular expansion device, including air bag
It is described recessed and intravascular stent, the air bag are olive shape, and this 3~5 grooves are uniformly distributed on the air bag of olive shape
Thickness at groove is more than air bag high spot surface thickness；
The gasbag outer surface of the olive shape is set with intravascular stent, and the air bag passes through tracheae and extraneous air pump
Connection.
The beneficial effects of the utility model are：Support, airbag design olive are inflated to intravascular stent using annular air-pocket
Olive shape, provided with groove, conveniently make blood circulation, the central vessel expansion operation of solution existing design can block sanguimotor
Problem, because not directly improved on air bag, original scaling is not reduced, in blood vessel transport, compared with thin vessels
In can also pass through, reduce operation risk.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the intravascular stent is metallic elastic network.
Further, the projection of the olive shape air bag and the outer surface of groove part are shiny surface.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is AA diagrammatic cross-sections of the present utility model；
In the accompanying drawings, the list of designations represented by each label is as follows：1st, air bag；2nd, intravascular stent；3rd, groove；4、
It is raised；5th, tracheae.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Fig. 1~2, including air bag 1 and intravascular stent 2, the air bag 1 is olive shape, olive shape it is described
It is uniformly distributed this 3~5 grooves 3 on air bag 1, the thickness at the groove 3 is more than surface thickness at air bag projection 4；
The outer surface of the air bag 1 of the olive shape is set with intravascular stent 2, and the air bag 1 passes through tracheae 5 and the external world
Air pump connects.
The intravascular stent 2 is metallic elastic network.
The projection 4 of the olive shape air bag 1 and the outer surface of the part of groove 3 are shiny surface.
Operation principle of the present utility model is：When carrying out vascular surgery, olive-type shell is inserted into patient vessel,
Angiemphraxis position is observed by angiography, when reaching closed position, tracheae is promoted, air bag is entered in blood vessel, beat
Drive air pump, airbag aeration expansion struts intravascular stent, now due to the design of olive shape air bag enable inside blood
Enough circulations, will not block blood circulation, increase the success rate of operation.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
