Abstract:
1. An adjustable access device, comprising: a housing having a cannula extending distally therefrom, the housing including a rotatable knob, the housing and the cannula defining a working channel extending therethrough for receiving an instrument, and the knob being rotatable relative to the cannula; and at least one cutting mechanism extending from at least one depressible tab coupled to the housing, the at least one cutting mechanism being movable relative to the cannula between a first position in which the at least one cutting mechanism puctures a sidewall of the cannula and a second position in which the cutting mechanism does not puncture the sidewall of the cannula; wherein rotating the knob when the cutting mechanism is in the first position causes the cutting mechanism to cut around a perimeter of the cannula to adjust a length of the cannula; and wherein the at least one cutting mechanism is configured to be depressed to move the cutting mechanism from the second position to the first position to puncture the cannula.
