Abstract

A bronchoscope locking mechanism includes a clamping member and a nut. The clamping member includes a threaded portion and a clamping surface that defines a compressible channel. The compressible channel is configured for communication with a tracheal tube. The nut has an inner threaded surface configured to cooperate with the threaded portion of the clamping member. The compressible channel is compressed from a first position defining a first diameter to a second position defining a second diameter when the nut is advanced over the threaded portion. The second diameter is smaller than the first diameter.

Claims

1. A bronchoscope locking mechanism comprising:

a clamping member including a threaded portion and a clamping surface, the clamping surface defining a compressible channel, the compressible channel configured for communication with a tracheal tube; and

a nut having an inner threaded surface and an outer surface;

the inner threaded surface configured to cooperate with the threaded portion of the clamping member, wherein the compressible channel has a first position defining first diameter and a second position defining a second diameter smaller than the first diameter, wherein as the nut is advanced over the threaded portion the nut interferes with the clamping member such that the compressible channel is moved from the first position towards the second position.

2. The locking mechanism of claim 1, wherein the nut is advanced proximally over the threaded portion to transition the compressible channel from the first position to the second position.

3. The locking mechanism of claim 1, wherein the nut is advanced distally over the threaded portion to transition the compressible channel from the first position to the second position.

4. The locking mechanism of claim 1, wherein the clamping member includes two or more lobes.

5. The locking mechanism of claim 1, wherein the clamping member includes a cantilevered member, the cantilevered member including the clamping surface.

6. The locking mechanism of claim 1, wherein the outer surface of the nut is configured to enhance tactile feel.

7. The locking mechanism of claim 6, wherein the outer surface of the nut includes at least one of rounded protrusions, petal-shaped protrusions, star-shaped protrusions, wings, or knurling.

8. A tracheal tube adaptor assembly comprising:

a bronchoscope;

an elongated tube having a proximal portion and a distal portion; and

a locking mechanism positioned proximal of the elongated tube, the locking mechanism defining a longitudinal axis, the locking mechanism comprising;

a clamping member including a threaded portion and a clamping surface, the clamping surface defining a compressible channel, the compressible channel axially aligned with the proximal portion of the elongated tube; and

a nut having an inner threaded surface and an outer surface;

the inner threaded surface configured to cooperate with the threaded portion of the clamping member, the compressible channel having a first position defining first diameter, wherein the bronchoscope is free to slide within the compressible channel, and a second position defining a second diameter smaller than the first diameter, wherein the bronchoscope is longitudinally fixed within the compressible channel, wherein as the nut is advanced over the threaded portion the nut interferes with the clamping member such that the compressible channel is moved from the first position towards the second position.

9. The assembly of claim 8, wherein the locking mechanism is positioned about the proximal portion of the elongated tube.

10. The assembly of claim 8, wherein the elongated tube has a proximal flange positioned near a proximal end of the elongated tube.

11. The assembly of claim 8, wherein the nut is advanced proximally over the threaded portion to transition the compressible channel from the first position to the second position.

12. The assembly of claim 8, wherein the nut is advanced distally over the threaded portion to transition the compressible channel from the first position to the second position.

13. The assembly of claim 8, further including an elbow portion, a first connector, and a second connector, the elbow portion includes a sidewall opening and is positioned distal to the locking mechanism and the second connector is positioned distal to the elbow portion, the elbow portion and second connector axially aligned with the locking mechanism, the second connector is positioned between the locking mechanism and elongated tube, the first connector includes an elongated body, an end of the elongated body coupled to the sidewall opening of the elbow portion.

14. The assembly of claim 13, wherein the elbow portion defines a first passage and the second connector defines a second passage in fluid communication with the first passage.

15. The assembly of claim 14, wherein the elongated body of the first connector defines a first lumen, the first lumen in fluid communication with the first and second passages through the sidewall opening of the elbow portion.

16. The assembly of claim 15, wherein the elongated body of the first connector further defines a second lumen adjacent to the first lumen, the second lumen in fluid communication with the first and second passages through the sidewall opening of the elbow portion.

17. The assembly of claim 16, wherein the first lumen is configured to permit fluid to flow into the first and second passages and inhibit fluid from flowing from the first and second passages and the second lumen is configured to permit fluid to flow from the first and second passages and inhibit fluid from flowing into the first and second passages.

18. The assembly of claim 13, wherein the elongated body of the first connector is orthogonal to the longitudinal axis.

19. The assembly of claim 13, wherein the clamping surface of the locking mechanism forms a seal with the bronchoscope.

20. A method for securing a bronchoscope comprising:

inserting a bronchoscope into a compressible channel of a locking mechanism; and

securing the bronchoscope in the locking mechanism by advancing a nut over a threaded portion of the locking mechanism, the nut compressing a clamping surface to reduce a diameter of the compressible channel.

21. The method of claim 20 further comprising inserting an instrument through the bronchoscope after the bronchoscope is secured in the locking mechanism.
