ABSTRACT:
The present disclosure relates to a surgical access member for establishing percutaneous access to a surgical worksite within tissue. The surgical access member includes a constricting mechanism that is adapted to removably receive a surgical instrument and resiliently transition between an open state and a constricted state. In the open state, insertion of the surgical instrument through the constricting mechanism is substantially uninhibited. In the constricted state, the constricting mechanism substantially limits transverse movement of the surgical instrument, and may facilitate the creation of a substantially fluid-tight seal therewith.
