A puncturing needle assisting tool. A first rotating portionrotates from an open to a closed position, around a first hinge connecting portionas the rotating center, to the surface side of an assisting tool main unitto close the surface opening of a first guide groove. A second rotating portionrotates from an open position to a closed position, around a second hinge connecting portionas the rotating center, to the surface side of an assisting tool main unitto close the surface openings of second guide groovesthrough. The puncturing needles move along the guide grooves to puncture into the body in a proper state, without shifting. Locking protrusionsmaintain the closed positions of the first and second rotating portionsrespectively.

Puncturing needle assisting tool

A suture tool for fixing the gastric wall to the abdominal wall includes a first puncture needle for insertion, a suture thread, a second puncture needle for removing the suture thread, a linear grasping member and one or more anchor member. The tip end portion of the suture thread is inserted into the first puncture needle and a hook of the linear grasping member is inserted into the second puncture needle for removing the suture thread inserted into the first puncture needle for securing the gastric wall to the abdominal wall.

Medical suturing tool with multiple puncture needles

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.
