Abstract

Claims (32)

1. A laryngoscope, comprising:

a laryngoscope blade;

a laryngoscope handle coupled to the laryngoscope blade;

an electronic display;

an adjustable display mechanism that adjustably couples the electronic display to the laryngoscope handle, the adjustable display mechanism providing relative rotation of the electronic display relative to the laryngoscope handle about a first axis and a separate second axis different than the first axis,

wherein the adjustable display mechanism includes a fixed sleeve coupled to the laryngoscope handle, a top rotatably coupled to the fixed sleeve for rotation relative to the fixed sleeve about the first axis, a pull connector slidably movable with respect to fixed sleeve and coupling the adjustable display mechanism to the laryngoscope handle.

2. The laryngoscope of claim 1 , wherein the pull connector includes a pull sleeve.

3. The laryngoscope of claim 2 , wherein the laryngoscope handle includes a receiving end, the adjustable display mechanism includes a connection shaft that is received by the receiving end of the laryngoscope handle, and the pull connector is used to connect the connection shaft to the receiving end of the laryngoscope handle.

4. The laryngoscope of claim 3 , wherein the adjustable display mechanism includes a dowel pin and the pull sleeve is slidably disposed along the connection shaft and is coupled to fixed sleeve via the dowel pin.

5. The laryngoscope of claim 4 , wherein the fixed sleeve includes a receiving hole and the connection shaft is received with the receiving hole of the fixed sleeve.

6. The laryngoscope of claim 5 , wherein the adjustable display mechanism includes a top and the fixed sleeve includes a shaft extending through the fixed sleeve and into the top.

7. The laryngoscope of claim 6 , further including a stop ring circumferentially surrounding the shaft in the top, the stop ring including stops for providing 180 degree rotation about the first axis in either direction, preventing binding or breaking of electrical wires within the adjustable display mechanism.

8. The laryngoscope of claim 1 , wherein the adjustable display mechanism includes a pivot for rotatably coupling the electronic display to the top for rotation relative to the top about the second axis.

9. The laryngoscope of claim 8 , wherein the relative rotation about the second axis is between 0 degrees and 90 degrees relative rotation about the second axis.

10. The laryngoscope of claim 8 , wherein the pivot is lockable to lock the electronic display in a fixed position relative to the top.

11. The laryngoscope of claim 1 , wherein the relative rotation about the first axis is between 0 degrees and 180 degrees relative rotation about the first axis.

12. The laryngoscope of claim 1 , wherein the laryngoscope handle and the adjustable display mechanism are coaxial.

13. The laryngoscope of claim 1 , wherein the electronic display includes a rear and the adjustable display mechanism adjustably couples the rear of the electronic display to the laryngoscope handle.

14. The laryngoscope of claim 1 , wherein the adjustable display mechanism includes several locking points, providing tactile feedback at the locking points and incremental movement without locking down the rotation.

15. An adjustable display mechanism for adjustably coupling an electronic display to a laryngoscope handle of a laryngoscope, comprising:

a fixed sleeve coupleable to the laryngoscope handle; and

a top rotatably coupled to the fixed sleeve for providing relative rotation of the electronic display relative to the laryngoscope handle about a first axis and including a pivot for providing relative rotation of the electronic display relative to the laryngoscope handle about a separate second axis different than the first axis,

wherein the adjustable display mechanism includes a fixed sleeve coupled to the laryngoscope handle, a top rotatably coupled to the fixed sleeve for rotation relative to the fixed sleeve about the first axis, a pull connector slidably movable with respect to fixed sleeve and coupling the adjustable display mechanism to the laryngoscope handle.

16. The laryngoscope of claim 15 , wherein the relative rotation about the first axis is between 0 degrees and 180 degrees relative rotation about the first axis.

17. The laryngoscope of claim 15 , wherein the relative rotation about the second axis is between 0 degrees and 90 degrees relative rotation about the second axis.

18. The laryngoscope of claim 15 , wherein the pivot is lockable to lock the electronic display in a fixed position relative to the laryngoscope handle.

19. A method of using the adjustable display mechanism of claim 15 , comprising:

rotatably coupling the top of the fixed sleeve to the electronic display;

coupling the fixed sleeve to the laryngoscope handle;

rotating the electronic display relative to the laryngoscope handle about the first axis;

rotating the electronic display relative to the laryngoscope handle about the separate second axis different than the first axis;

viewing the electronic display while performing laryngoscopy.
