Abstract:
1. A gas-assisted electrosurgical accessory connector formed by two mating pieces connectable to one another with a relative connection movement along an axis toward one another, comprising: a sealing surface formed on one mating piece and extending generally parallel with the axis for a distance along the axis; a resilient radial sealing member carried on the other mating piece at a location which contacts and seals against the sealing surface with radial force upon the two mating pieces connecting with relative connection movement; a retention mechanism operative between the mating pieces when connected with relative connection movement, the retention mechanism restraining the connected mating pieces against separation from one another with movement away from one another along the axis, wherein the retention mechanism further comprises: a recess formed on one of the mating pieces; and a retention member carried on the other one of the mating pieces, the retention member moving into the recess upon the two mating pieces connecting with relative connection movement, the retention member moving out of the recess with manual force applied between the two connected mating pieces to separate the connected mating pieces from one another.
