A clip or flexible handles extension facilitate simultaneous retention and operation of a bronchoscope and associated bronchoscopic tools held in one hand to allow operation by a single practitioner. Also provided is an adapter for the connection port of the working channel of a bronchoscope which performs both sealing and tool-locking functions. Also disclosed is a guide sheath arrangement with a reduced flexibility proximal portion to facilitate insertion of tools into the guide sheath.
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
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; anda 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; andwherein the key has a U-shaped cut-out to accept an undercut formed on the access port therein. 2. The adapter of claim 1, wherein said elastomeric clamping block is formed as a substantially cylindrical collar with a central clamping bore for passage of the tool. 3. The adapter of claim 2, wherein said central clamping bore features at least one inwardly projecting, circumferential ridge. 4. The adapter of claim 2, wherein said substantially cylindrical collar has at least one conical surface portion, said tightening mechanism including an axially displaceable element deployed for engaging said at least one conical surface so as to apply an inward locking pressure on said central clamping bore. 5. The adapter of claim 1, wherein said elastomeric valve and said elastomeric clamping block are implemented as a unitary elastomeric insert deployed within said housing. 6. The adapter of claim 1, wherein said elastomeric valve is implemented as an elastomeric membrane cut along a slit. 7. The adapter of claim 1, wherein the key is inserted within said through hole from an exterior position of said housing. 8. The adapter of claim 1, wherein a portion of said key remains exterior to said housing when inserted into the through hole.
