Abstract
The invention relates to a device for joining hollow organs with an elongated holder and a needle carrier which is positioned at one end of the holder, where the needle seat extends radially, forming an overhang projecting beyond the periphery of the holder, as well as with a plurality of needles which are disposed standing vertically on the projecting overhang of the needle seat, surrounding the holder.
Claims32
Device comprising:
- a lengthy holder for joining hollow organs or for closing blood vessels,
- a needle carrier, located at one end of the holder, wherein a needle seat forming an overhanging projection projects radially beyond the periphery of the holder and wherein a sleeve with a passage extending in the axial direction of the needles is located adjacent to the holder and above the needle points, the internal diameter of which is greater than the diameter of the needle array, and wherein the sleeve possesses elements in the area facing away from the needle points to constrict its passage.
Procedure to join a first opening in a hollow organ with a second opening in a second hollow organ, comprising the steps of:
- inserting a first array of needles into the first opening, inserting a second array of needles with the ends of the needles in front into the second opening, where the end of each needle in the first array is connected to the end of a needle in the second array by means of a suture, pushing the needles of each array jointly through the wall of the particular hollow organ along its opening with the needle points in front in each case, and subsequently pulling tight the sutures and tying the two ends of each suture together.
