Abstract

Abstract An adapter 10 and a mating trocar element 20 for use in a trocar assembly 30. The adapter 10 is cylindrical in shape with a continuous bore 12 running therethrough. A first end 14 of the adapter 10 has a reduction in diameter and a second end 16 of the adapter 10 is internally threaded 18 along the bore 12. The first end 14 is sized so as to allow frictional engagement with the end of a mating flexible tube 32. The reduction in diameter of the first end 14 preferably corresponds to the wall thickness of the mating flexible tube 32, so as to maintain a continuous outer surface between the adapter 10 and the mating tube of constant outer diameter. The second end 16 is internally threaded 18 along the bore 12 so as to allow fastenable engagement with a threaded end 24 of the mating trocar element 20. The mating trocar element 20 has the shape of a rod with a first end 22 being formed with or machined to a sharp point and a second end 24 having a reduction in diameter which is threaded 26 so as to mate with the threaded bore 18 of the adapter 10. The reduction in diameter of the second end 24 preferably corresponds to the wall thickness of the threaded bore portion 18 of the adapter 10, so as to maintain a continuous outer surface between the trocar element 20 and the adapter 10 of constant outer diameter.
