Disposable Gynecologic Instrument For Dilation Of Body Cavities By Fluid Injection

Abstract

Disposable gynecologic instrument for dilation of body cavities by fluid injection, the construction according to the invention, include the instrument body ( 1 ) to which it has from the bottom tightly fixed a handle ( 2 ) with the reservoir ( 3 ) whilst is on the frontal part −θ f the instrument body ( 1 ) projected is the trigger ( 4 ) positioned slidingly and designed for pressing with two fingers, which is by screw ( 41 ) connected to the main piston ( 42 ) movable within the cylinder, around which is placed a bigger spring ( 43 ) and where the outlet of cylinder is connected to one branch of the three-way pipeline ( 44 ), the other two of which are connected, one on the upper irreversible valve ( 12 ), and the other to the lower irreversible valve ( 22 ); and where is also on the front side of the instrument body ( 1 ) by screw thread and sealingly attached the main pipe ( 5 ), formed with longitudinal ribs ( 51 ) positioned crosswise and a series of aslope placed ribs ( 52 ) of circular perimeter, which increase the stiffness of the main pipe ( 5 ) in which projected part is by screw thread fixed the support ( 6 ) for the body ( 100 ) of the dilation probe with the holding fixture ( 7 ) of the dilation balloon, and where on the body ( 1 ), on the upper right side is the button ( 8 ) of a squeezer with vent protector ( 9 ), while in front of it is the holder ( 10 ) for the small spring ( 11 ) of the upper irreversible valve ( 12 ).

1 . Disposable gynecologic instrument for dilation of body cavities by fluid injection, characterised in that, the instrument body ( 1 ) has from the bottom tightly fixed a handle ( 2 ) with the reservoir ( 3 ) whilst is on the frontal part of the instrument body ( 1 ) projected the trigger ( 4 ) slidingly positioned and designed for pressing with two fingers, which is by screw ( 41 ) connected to the main piston ( 42 ) movable within the cylinder around which is placed a bigger spring ( 43 ) and where the outlet of cylinder connected to one branch of the three-way pipeline ( 44 ), which other two branches are connected, one on the upper irreversible valve ( 12 ), and the other to the lower irreversible valve ( 22 ); and where is also on the front side of the instrument body ( 1 ) is by screw thread and sealingly attached the main pipe ( 5 ), formed with longitudinal ribs ( 51 ) positioned crosswise and a series of aslope placed ribs ( 52 ) of circular perimeter, which increase the stiffness of the main pipe ( 5 ) in which projected part is by screw thread fixed the support ( 6 ) for the body ( 100 ) of the dilation probe with the holding fixture ( 7 ) of the dilation balloon, and where on the body ( 1 ), on the upper right side is the button ( 8 ) of a squeezer with vent protector ( 9 ), while in front of it is the holder ( 10 ) for the small spring ( 11 ) of the upper irreversible valve ( 12 ). 
     
     
         2 . Disposable gynecologic instrument for dilation of body cavities by fluid injection, according to  claim 1 , characterised in that, the handle ( 2 ) is attached to the body ( 1 ) from the bottom, by screw ( 24 ) within the cavity ( 25 ), whilst on the entire perimeterof the upper edge of handle ( 2 ) is positioned the gasket ( 26 ) of the reservoir ( 3 ) where within the reservoir ( 3 ) is extended the lower cannula ( 21 ) for passing incompressible fluid from the reservoir ( 3 ) in the body ( 1 ), where the cannula ( 21 ) on its upper end has a irreversible-valve ( 22 ), which has, in the seat of the sealing ball, positioned a sealing ball pushed downwards by a small spring ( 23 ) for the closing of irreversble valve ( 22 ) disabling return of incompressible fluid into the reservoir ( 3 ). 
     
     
         3 . Disposable gynecologic instrument for dilation of body cavities by fluid injection, according to the  claims 1  and  2 , characterised in that, the vent arrangement is located on the upper rear end of the body ( 1 ) and consists of button ( 8 ) of a squeezer with vent protector ( 9 ), while along the axis below the O-ring ( 81 ) is placed stopper ( 82 ) of exhaust valve, piston ( 83 ) of the vent, movable within the vent piston cylinder below which is located the special gasket ( 84 ) under which is lock ( 85 ) of the vent piston, whilst at the bottom is positioned a special gasket ( 86 ). 
     
     
         4 . Disposable gynecologic instrument for dilation of body cavities by fluid injection, according to the patent requirements  1 ,  2  and  3 , characterised in that, the incompressible fluid in gynecologic instrument for dilation of body cavities is used a distilled water. 
     
     
         5 . Disposable gynecologic instrument for dilation of body cavities by fluid injection, according to the  claims 1 ,  2 ,  3  and  4 , characterised in that, the dilation probes body ( 100 ) is closed with a closure ( 110 ) through which is dragged a top ( 120 ) of the dilation probe for implanting in the body cavity, and that on the holding fixture ( 7 ) of hollow cannulla, of mandrel ( 160 ) is locked a catheter balloon of the dilation probe by lock ( 71 ) providing the stiffness of the arrangement. 
     
     
         6 . Disposable gynecologic instrument for dilation of body cavities by fluid injection, according to the  claims 1  to  5 , characterised in that, the top of the probe ( 120 ) is made so that is arround the hollow cannulla of the mandrel ( 160 ) wrapped an inner-rubber layer ( 170 ) which all over itself has a strengthened layer made of woven material ( 180 ), and that is all over enwrapped the outer rubber layer ( 190 ).
