Abstract:
1. A method of manufacturing a constricting mechanism for use with a surgical access device to limit transverse movement of a surgical instrument inserted therethrough, comprising the steps of: providing a proximal member including a first plurality of pins extending outwardly therefrom; providing a distal member including a second plurality of pins extending outwardly therefrom; providing a plurality of rods including structure adapted to receive one of the first plurality of pins and one of the second plurality of pins; and positioning the plurality of rods between the proximal and distal members such that the plurality of rods each receive one of the first plurality of pins and one of the second plurality of pins to permit relative rotation between the proximal and distal members such that the constricting mechanism is repositionable between a first state, in which the constricting mechanism is adapted to permit insertion of the surgical instrument, and a second state, in which the constricting mechanism is adapted to engage the surgical instrument to limit transverse movement thereof.
