Abstract
The utility model discloses a kind of band sacculus adjustable bending sheath for Coronary venography, including：Double-deck body, annular balloon, traction fiber and handle；Wherein described bimetallic tube body has proximally and distally, and the distal end is provided with stretch section, and near-end connection handle simultaneously passes through handle；The double-deck body includes the cavity between inner and outer tubes, inner and outer tubes with closing, inner tube of the traction fiber through handle and double-deck body；The outer tube is provided with annular opening groove, annular opening groove connection annular balloon in the position close to distal tip.The utility model structure is novel, easy to use, and coronary vein oral area is blocked by annular balloon, the fully development of coronary vein distal end can be made, it is easy to clear and definite coronary venous system, improves coronary venous system radiography efficiency and operation precision, be prevented effectively from complication.
Description
Technical field
The utility model belongs to field of medical device, more particularly to a kind of band sacculus adjustable bending for Coronary venography
Sheath.
Background technology
Current coronarography be diagnose coronary atherosclerotic heart disease (coronary heart disease) one kind it is conventional and
Effective method.Selective coronary arteriography is exactly to utilize angiography machine, passes through the cardiac catheter percutaneous puncture of special sizing
Enter lower limb femoral artery, driven in the wrong direction along descending aorta to root of ascending aorta, then seek the insertion of left or right coronary ostium, injection is made
Shadow agent, makes coronary artery develop.Thus can be clearly by whole left or right trunk coronarius and its lumen of vessels of branch
Show, it will be appreciated that blood vessel whether there is stenotic lesions presence, to diseased region, scope, the order of severity, situation of vascular wall etc.
Make and clarifying a diagnosis, determine therapeutic scheme (intervention, operation or medical treatment), may further be used to judge curative effect.This be it is a kind of more
Safe and reliable invasive diagnostic techniques, has been widely used in clinic, it is considered to be " goldstandard " of diagnosis of coronary heart disease.
But during the existing approach adjustable bending sheath row Coronary venography through femoral vein, coronary artery ostium venosum cordis is blocked due to a lack of sacculus
Portion, most of contrast agent backflows, it is difficult to make the fully development of coronary vein distal end.
Utility model content
The purpose of this utility model is that there is provided a kind of band sacculus for Coronary venography for the defect of prior art
Adjustable bending sheath.
To achieve these goals, the utility model uses following technical scheme：A kind of band for Coronary venography
Sacculus adjustable bending sheath, including：Double-deck body, annular balloon, traction fiber and handle；Wherein described bimetallic tube body has near-end and remote
End, the distal end is provided with stretch section, and near-end connection handle simultaneously passes through handle；The double-deck body includes inner and outer tubes, interior
There is the cavity of closing, inner tube of the traction fiber through handle and double-deck body between pipe and outer tube；The outer tube is close
The position of distal tip is provided with annular opening groove, annular opening groove connection annular balloon.
Outer tube stretches out handle peripheral hardware in near-end and is equipped with breather valve.
The maximum volume of the annular balloon is 1.5~2mL.
The distance of the annular opening slot distance distal tip is 1.5cm.
Adjustable bending sheath of the present utility model uses the structure of double-deck body, and in the position close to stretch section termination 1cm
It is provided with the annular balloon that the cavity between inner and outer tubes is connected.During radiography, adjustable bending sheath is extend into coronary vein mouthful
Portion, charger is connected by breather valve, and annular balloon is inflated, prominent after annular balloon inflation to block coronary vein mouthful
Portion, can make the fully development of coronary vein distal end, be easy to clear and definite coronary venous system, catheter guidance precise manipulation.After radiography, pass through
Gas valve bleeds off annular balloon, annular balloon is restored to the original state, you can take out adjustable bending sheath.
The utility model structure is novel, easy to use, blocks coronary vein oral area by annular balloon, can make coronary vein
Distal end fully development, is easy to clear and definite coronary venous system, improves coronary venous system radiography efficiency and operation precision, effectively
Avoid complication.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the utility model with sacculus adjustable bending sheath.
Embodiment
The application is described further with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the utility model with sacculus adjustable bending sheath, including：Double-deck body, annular balloon 1, lead
Draw silk 2 and handle 3.
Wherein double-deck body has proximally and distally, is distally provided with stretch section 4, and near-end connection handle simultaneously passes through handle.
Double-deck body includes the cavity between inner tube 5 and outer tube 6, inner and outer tubes with closing.Traction fiber passes through handle and bimetallic tube
The inner tube of body.
Outer tube is provided with annular opening groove, annular opening groove connection annular balloon, ring in the position close to distal tip 1cm
The maximum volume of shape sacculus is 2mL.Outer tube stretches out handle peripheral hardware in near-end and is equipped with breather valve 7.
Adjustable bending sheath using double-deck body structure, and be provided with the position close to stretch section termination 1.5cm with it is interior
The annular balloon that cavity between pipe and outer tube is connected.During radiography, adjustable bending sheath is extend into coronary vein oral area, by breather valve
Charger is connected, annular balloon is inflated, protrusion blocks coronary vein oral area after annular balloon inflation, can make coronal quiet
The fully development of arteries and veins distal end, is easy to clear and definite coronary venous system, catheter guidance precise manipulation.After radiography, bled off by gas valve
Annular balloon, makes annular balloon restore to the original state, you can take out adjustable bending sheath.
It is described above, only it is preferred embodiment of the present utility model, any type of not is done to the utility model
Limitation.Every any simple modification, equivalent change substantially made according to technology of the present utility model and method to above example
Change with modification, in the range of still falling within technology of the present utility model and method scheme.
