Abstract

An obturator tip for a trocar is disclosed. The obturator comprises a shaft having a distal or penetration end for insertion into a patient and a handling or proximal end for gripping by a surgeon. The penetration end of the shaft comprises a tip having an upper flat face and a lower flat face which taper away from the shaft toward the distal end. The tip further comprises flat side faces which also taper or slope from the shaft toward the distal end. A glide tip has a rounded end and extends outwardly along the side faces.

Claims

1. A tip for an obturator which is used in a trocar, said obturator having a distal or penetration end, a proximal or handling end, and a shaft between the distal and proximal ends, said tip comprising:

(a.) upper and lower flat faces which slope from the shaft of the obturator toward the distal end of the obturator;

(b.) side faces which are flat, which are between the upper and lower flat faces, and which slope from the shaft toward the distal end of the obturator; and

(c.) a glide tip which extends outwardly from the side faces in a plane substantially equidistant between the upper and lower faces and radially along the side faces, the glide tip having a rounded portion at the distal end of the obturator and a beveled portion along the side faces, the beveled portions having a downward bevel.
