Abstract
A laryngoscope having a blade with various motion functions. The motion functions can be invoked by pushbutton type controls on the handle of the laryngoscope, and can be accomplished mechanically, electrically, or in combination. In addition to one motion suitable for lifting the tongue, the blade can also be adjusted as to its direction of projection from the handle and distance from the handle.
Claims60
A laryngoscope comprising:
- a handle having a front side, a proximal end, and a distal end;
- a blade movably coupled to the handle and projecting from the front side of the handle proximate the distal end of the handle;
- and
- a mechanism for moving the blade relative to the handle, the mechanism further comprising:
- a guide linkage constraining the blade to move in at least one predetermined path relative to the handle, wherein the at least one predetermined path is selected from a group consisting of:
- a first predetermined path, wherein the first predetermined path comprises a first designated path traveled on a flat plane by the blade, the flat plane simultaneously bisecting a handle length and a blade length, wherein during the travel an angle between the handle length and the blade length remains constant while the blade translates along the handle length,
- a second predetermined path wherein the second predetermined path comprises a second designated path traveled on a flat plane by the blade, the flat plane simultaneously bisecting a handle length and a blade length, wherein the blade pivots about a fulcrum positioned on the flat plane where the handle and the blade intersect, the pivoting causing a plurality of inclination angles between the blade length and the handle length on the flat plane,
- a third predetermined path wherein the third predetermined path comprises a third designated path traveled on a flat plane by the blade, the flat plane simultaneously bisecting the handle along a substantially widthwise direction thereof and a blade length, wherein during the travel the blade pivots about an axis through the handle length while maintaining a constant angle to the handle, and
- a fourth predetermined path extending transversely relative to a length of the handle, wherein the fourth predetermined path further comprises a fourth designated path traveled on a flat plane by the blade, the flat plane simultaneously bisecting a handle length and a blade length, wherein during the travel an angle between the handle length and the blade length remains constant while the blade moves transversely toward or away from an axis through a center of the blade;
- at least one motor housed in the handle, the at least one motor having a motion output when the motor is operating;
- and
- at least one transmission for each one of the at least one motors, wherein said at least one transmission moves the blade in the at least one predetermined path responsive to operation of at least one motor.
