Abstract:
1. A sealing and locking adapter for attachment to an access port of a working channel of a bronchoscope to allow insertion and locking of a tool while sealing the access port when not in use, the adapter comprising: a housing configured for mating with the access port of the working channel of the bronchoscope, where the housing includes a through hole formed in a lateral wall of the housing configured to accept a key inserted therein; a sealing arrangement deployed within said housing, said sealing arrangement including an elastomeric valve elastically biased to a normally-closed state wherein said elastomeric valve forms part of the sealing arrangement for preventing passage of air through the access port of the working channel even when said elastomeric valve is in a non-deformed state, said elastomeric valve being configured to allow insertion of the tool through said valve and into the working channel; and a clamping arrangement deployed within said housing, said clamping arrangement including an elastomeric clamping block, insertable into said housing, and a tightening mechanism, said tightening mechanism being manually operable to deform said elastomeric clamping block so as to lock in position the tool inserted through said housing and into the working channel, wherein said key secures said housing, including said clamping arrangement to the bronchoscope to maintain contact pressure between said housing and said access port of the working channel; and wherein the key has a U-shaped cut-out to accept an undercut formed on the access port therein.
