Auxiliary device for a puncture needle

Abstract

An auxiliary device for a puncture needle allowing an easier manipulation of puncture needles as well as being capable of improving the suture stability. The auxiliary device for a puncture needle comprises a plate-shaped auxiliary device main body on the surface of which parallel guide grooves were formed, and a plate-shaped rotating-sliding contact part rotatably attached to one of the edge parts of the auxiliary device main body. Moreover, a stabilization plate was provided at the lower end part of the auxiliary device main body. And, a window part for confirming an insertion-puncture needle-outer needle and a pullout-puncture needle were provided at the lower part side portion of the auxiliary device main body. Moreover, a projecting edge part was formed at the upper end part of the auxiliary device main body, and an opening side width of a portion located at the projecting edge part of the guide grooves was made wider than the width of the other portion of the guide grooves.

1 . An auxiliary device for puncture needle used when plural puncture needles employed in securing an organ to the skin portion with surgical suture make a puncture in the aforementioned skin portion through to the aforementioned organ, the auxiliary device comprising an auxiliary device main body, on the surface of which plural parallel guide grooves are formed so as to be able to install the aforementioned plural puncture needles movable in the axial direction, and the rotating-sliding contact part slidingly contacting to the peripheral surface of the aforementioned puncture needles installed in the aforementioned guide grooves by being rotatably attached to one of the edges approximately parallel to the extending direction of the aforementioned guide grooves in the aforementioned auxiliary device main body and by rotating to the surface side of the aforementioned auxiliary device main body. 
   
   
       2 . An auxiliary device for puncture needle according to  claim 1 , wherein at least the aforementioned auxiliary device main body out of the aforementioned auxiliary device main body and the aforementioned rotating-sliding contact part is formed in a plate-shape, and the aforementioned guide grooves are formed from one end to the other end of the aforementioned auxiliary device main body. 
   
   
       3 . An auxiliary device for puncture needle according to  claim 1 , wherein a stabilization plate, the bottom surface of which is formed on a plane perpendicularly intersecting with the extending direction of the aforementioned plural guide grooves, is provided at a portion placed to the aforementioned skin portion side in the aforementioned auxiliary device main body. 
   
   
       4 . An auxiliary device for puncture needle according to  claim 1 , wherein the projecting edge part protruding toward the aforementioned surface side is formed at a portion opposite to the portion placed at the aforementioned skin portion in the aforementioned auxiliary device main body so that the aforementioned rotating-sliding contact part is positioned inside the aforementioned projecting edge part when being rotated to the surface side of the aforementioned auxiliary device main body, and at the same time, the opening side width of a portion constituting the aforementioned guide grooves in the aforementioned projecting edge part is larger than the width of the other portion of the aforementioned guide grooves. 
   
   
       5 . An auxiliary device for puncture needle according to  claim 1 , wherein a confirmation window part for confirming the puncture needle placement is provided at a portion placed to the aforementioned skin portion side of at least either one of the aforementioned auxiliary device main body and the aforementioned rotating-sliding contact part.
