OBTURATOR WITH INSTRUMENT RETENTION

摘要

A surgical device having an obturator that includes a sidewall having an arcuate outer surface is disclosed. The sidewall may have an arcuate inner surface that defines a central longitudinal channel into which an instrument may be inserted. The sidewall may also define at least one bore extending between the arcuate inner and outer surfaces of the sidewall. An instrument retention element engages the arcuate outer surface of the obturator such that the instrument retention element extends radially into the bore. At least a portion of the instrument retention element may extend radially inward of the arcuate inner surface so as to engage, and restrict relative movement of, an instrument inserted into the central longitudinal channel of the obturator.
