Abstract

A surgical apparatus (10, 10A, 10B, 10C) includes a hollow cannula (20, 20A, 20B, 20C) including least one locking aperture (34, 34A, 34B, 34C) extending therein. The apparatus (10, 10A, 10B, 10C) has a hollow tip (40, 40A, 40B, 40C, 40D, 40E, 40F, 40G, 40H, 40I) with a base portion (42, 42B, 42C, 42D, 42E, 42F, 42G, 42H, 42I) including at least one projection (50, 50A, 50B, 50C, 50D, 50E, 50F, 50G, 50H, 50I) extending within the at least one locking aperture (34, 34A, 34B, 34C) of the cannula (20, 20A, 20B, 20C) for maintaining the tip (40, 40A, 40B, 40C, 40D, 40E, 40F, 40G, 40H, 40I) in position. The tip (40, 40A, 40B, 40C, 40D, 40E, 40F, 40G, 40H, 40I) has an exposed end portion (44, 44A, 44B, 44C, 44D, 44E, 44F, 44G, 44H, 44I) extending beyond the cannula (20, 20A, 20B, 20C) and defines at least one port (48, 48A, 48B, 48C, 48D, 48E, 48F, 48G, 48H, 48I) in fluid communication with the interior of the cannula (20, 20A, 20B, 20C).

Dependent claims

A surgical apparatus, said apparatus comprising:

a hollow cannula having a proximal end, a distal end, and defining an interior passage extending from said proximal end to said distal end, said interior passage defining a central cannula axis, said cannula including at least one locking aperture extending transversely relative to said central cannula axis;
and
a hollow tip having a base portion affixed within the distal end of said cannula, said base portion including at least one projection extending within said at least one locking aperture of said cannula for maintaining said tip in position at said distal end of said cannula, said tip having an exposed end portion extending beyond said distal end of said cannula and defining at least one port in fluid communication with the interior passage defined by said cannula.
