Abstract
The utility model relates to a heart mitral valve expansion saccule pipe which can be used for adjusting the degree of curvature on a handle. A directional traction device is arranged in a near a saccule segment on the existing outer sleeve pipe and is extended to the handle. A traction pipe on the handle is operated to make a near sacculus segment pipe do bending with different degrees for making a sacculus easier to enter a mitral valve mouth. When the utility model is not used, a patent inner pipe can be simultaneously used for measuring the pressure of a left ventricle.
Description
This utility model relates to a kind of heart Bicuspid valve dilating sacculus pipe that can manipulate flexibility on handle by traction apparatus directly.At present, it is to be right after by internal and external casing and sacculus to form that the purchasing of the balloon tube of known InoueShi and domestic imitation product made, during operation technique, before passing through mitral orifice, must in inner sleeve, insert a terminal crooked bougie earlier, regulate the flexibility of nearly sacculus section pipe with this, difficult sometimes two lobe mouths by severe stenosis cause operation unsuccessful.And, the inner sleeve that is stopped up by bougie, not energy measurement left ventricular pressure, desire will be surveyed left ventricular pressure, calculates the lobe of striding of dilatation front and back and presses, as an important indicator of instant judgement operative effect, must do Arterial system intubate (Chinese magazine 1994,2 phases, 95 pages) in addition.
The purpose of this utility model provides a kind of adjustable flexure type heart Bicuspid valve dilating sacculus pipe, can handle its camber on the handle of pipe, makes sacculus be easy to enter the mitral orifice of severe stenosis; Can utilize open interior tube chamber to carry out the left ventricle pressure measurement simultaneously again,, remove the purpose of many formalities of arterial cannulation pressure measurement and expense to reach the shortening operating time.
The purpose of this utility model is achieved in that in the nearly section of sacculus trocar sheath inserts elongated spring, it is to traction steel wire of side, extend on the handle, make the traction tube of withstand voltage leakproof, draw this traction tube can handle its flexibility, tube chamber also easily makes sacculus enter left ventricle in inserting without bougie.
Owing to adopt such scheme, open interior tube chamber just can be used for measuring left ventricular pressure.
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is the vertical section structural map of embodiment.1. little becket 2. steel wire patchholes 3. traction steel wires 4. camber springs 5. traction tubes among the figure.
Specific implementation method is, the lower end of little becket (1) and elongated (wide 2.5mm, long 200mm) camber spring (4) weld, and sidetracking one aperture (2) is inserted thin traction steel wire (3) and fastens.Steel wire extends outside the handle, makes the traction tube (5) of withstand voltage leakproof.
Claims (2)
1. heart Bicuspid valve dilating sacculus pipe, be linked in sequence by sacculus, little becket, internal and external casing, handle, it is characterized in that: the little becket lower end that links to each other with sacculus links to each other with elongated camber spring, and offside embeds traction steel wire, extends the outer flexibility that can handle sacculus end pipe of handle.
2. balloon tube according to claim 1 is characterized in that: the traction tube that increases a withstand voltage leakproof on the handle of balloon tube.
