Abstract
The utility model relates to a cardiovascular operation, concretely relates to cardiovascular expansion device, including cylindric shell and vascular support, the head of cylindric shell just is cylindrical in the middle part for the toper, the inside of cylindric shell is equipped with the cavity, conical head and columniform bottom all are equipped with the through -hole, the through -hole all communicates with the cavity, blood vessel bracket rails is equipped with annular gasbag, the lateral wall of annular gasbag is equipped with the cylindrical arch that prevents vascular support and drop, the annular gasbag passes through the trachea and is connected with external air pump, the utility model provides a cardiovascular expansion device utilizes annular gasbag to aerify the support to vascular support, and the gasbag design circularizes, and the problem that blood circulation can be blocked in the vasodilatation operation of existing design center is solved in the convenient inside blood circulation that makes.
Description
Technical field
This utility model relates to operation on vessels of heart, is specifically related to a kind of cardiovascular expansion device.
Background technology
Heart is the muscular organ of a hollow, is positioned at the middle part in thoracic cavity, and be divided into two chambers in left and right by an interval, each chamber is divided into again ventricle two parts of superposed atrium and bottom.Atrium is collected into heart blood, and Ve goes out the heart.Import and the outlet of ventricle have valve, ensure blood one-way flow.Cardiovascular is made up of the heart and blood vessel, and blood vessel comprises again tremulous pulse, vein and blood capillary.When carrying out cardiovascular expansion to patient clinically, majority mounting bracket or sacculus in patient's cardiovascular, but because cardiovascular pipeline is thinner, craft loads support or sacculus is just more difficult, and complete occlude blood circulation in process of expansion, Ink vessel transfusing vegetation attrition crushing cannot be completely removed, and adds work difficulty to medical worker.
In prior art, comparatively ideal dilating sacculus is aboveground sacculus, be recognized any polyethylene balloon be better than for equal object, but aboveground sacculus is complete occlude blood circulation in process of expansion, easily cause the symptom such as hypotension, loss of consciousness, tic, add great work difficulty to medical worker.
Utility model content
For solving the problem, this utility model provides a kind of cardiovascular expansion device, and concrete technical scheme is as follows:
A kind of cardiovascular expansion device, comprise cylindrical outer casing and intravascular stent, the head of described cylindrical outer casing is taper and middle part is cylindrical, the inside of described cylindrical outer casing is provided with cavity, head and the columniform bottom of described taper are equipped with through hole, and all and cavity connects, described intravascular stent inwall is provided with annular air-pocket to described through hole, the lateral wall of described annular air-pocket is provided with the cylindrical protrusions preventing intravascular stent from coming off, and described annular air-pocket is connected with extraneous air pump by trachea.
Preferably, described intravascular stent is metallic elastic network.
Preferably, described cavity and annular air-pocket size adapt.
Preferably, described annular air-pocket inside is shiny surface.
Beneficial effect:
This utility model provides a kind of cardiovascular expansion device, this utility model utilizes annular air-pocket to carry out inflated supporting to intravascular stent, airbag design circularizes, and facilitates inside to make blood circulation, solves the problem of existing design centre vasodilation operation meeting occlude blood circulation.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is cardiovascular expansion device structural representation;
Fig. 2 is cardiovascular expansion device generalized section;
Fig. 3 is cardiovascular expansion device top view.
Detailed description of the invention
For making the object of this utility model embodiment, technical scheme and advantage clearly, below the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Embodiment 1:
As Fig. 1, Fig. 2, a kind of cardiovascular expansion device shown in Fig. 3, comprise cylindrical outer casing 1 and intravascular stent 2, the head of described cylindrical outer casing 1 is taper and middle part is cylindrical, the inside of described cylindrical outer casing 1 is provided with cavity 3, head and the columniform bottom of described taper are equipped with through hole 4, described through hole 4 is all communicated with cavity 3, described intravascular stent 2 inwall is provided with annular air-pocket 5, the lateral wall of described annular air-pocket 5 is provided with the cylindrical protrusions 6 preventing intravascular stent from coming off, described annular air-pocket 5 is connected with extraneous air pump by trachea 7, described intravascular stent 2 is metallic elastic network, described cavity 3 adapts with annular air-pocket size, described annular air-pocket inside is shiny surface.
It should be noted that, when carrying out vascular surgery, cylindrical outer casing is inserted in patient vessel, observes angiemphraxis position by angiography, when arriving closed position, promote trachea, make annular air-pocket enter into blood vessel, open air pump, intravascular stent struts by annular air-pocket inflation, now because the design of annular air-pocket makes inner blood to circulate, can not circulate by occlude blood; Cylindrical protrusions on annular air-pocket lateral wall prevents intravascular stent from dropping while can blocking mobile annular air-pocket, increases the success rate of operation.
This utility model provides a kind of cardiovascular expansion device, this utility model utilizes annular air-pocket to carry out inflated supporting to intravascular stent, airbag design circularizes, and facilitates inside to make blood circulation, solves the problem of existing design centre vasodilation operation meeting occlude blood circulation.
This above embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
