A laryngoscope with a handle, at the distal end of which a blade is arranged at an angle to the longitudinal axis of the handle, wherein a channel for receiving an image carrier of a video endoscope is formed in the handle and in the blade such that the channel, in a transition area from the handle to the blade, merges in a radius from the handle into the blade. In order to provide a laryngoscope which, while being easy to handle, ensures insertion of the image carrier into the channel in a way that protects material, in the transition area from the handle into the blade, at least one run-on bevel is formed in the interior of the channel.
1. A laryngoscope, comprising:
a handle;
a blade at a distal end of the handle, the blade arranged at an angle to a longitudinal axis of the handle; and
a channel for receiving an image carrier of a video endoscope, the channel formed in the handle and in the blade such that the channel, in a transition area from the handle to the blade, merges in a radius from the handle into the blade;
wherein in the transition area from the handle into the blade, which is formed as the radius, at least one run-on bevel is formed in an interior of the channel and on an inner wall of the channel; and
wherein the at least one run-on bevel is composed of several ribs arranged at a distance from one another.
2. The laryngoscope according to claim 1 , wherein the ribs are arranged parallel to one another.
3. The laryngoscope according to claim 1 , wherein the ribs, viewed in a direction of insertion of the image carrier, are arranged on the inner wall of the channel at a location proximal from a portion of the radius at which curvature of the radius is greatest.
4. The laryngoscope according to claim 1 , wherein the ribs, facing into the channel, are oriented at an angle with respect to the longitudinal axis of the handle.
5. The laryngoscope according to claim 1 , wherein the ribs have an increasing radial thickness along their axial length, from proximal to distal.
6. The laryngoscope according to claim 1 , wherein the ribs are formed all the way round an entire circumference of the inner wall of the channel.
7. The laryngoscope according to claim 1 , wherein the ribs are formed only in sections about a circumference of the inner wall of the channel.
8. The laryngoscope according to claim 1 , wherein the angle at which the blade is angled with respect to the longitudinal axis of the handle is 70° to 90° .
9. The laryngoscope according to claim 1 , wherein the handle and the blade are connected to each other releasably.
10. The laryngoscope according to claim 2 , wherein the ribs, viewed in a direction of insertion of the image carrier, are arranged on an inner wall of the channel at a location proximal from a portion of the radius at which curvature of the radius is greatest.
11. A laryngoscope, comprising:
a handle;
a blade at a distal end of the handle, the blade arranged at an angle to a longitudinal axis of the handle; and
a channel for receiving an image carrier of a video endoscope, the channel formed in the handle and in the blade such that the channel, in a transition area from the handle to the blade, merges in a radius from the handle into the blade;
wherein in the transition area from the handle into the blade, which is formed as the radius, at least one run-on bevel is formed in an interior of the channel;
wherein the at least one run-on bevel is composed of several ribs arranged at a distance from one another; and
wherein the ribs have an increasing radial thickness along their axial length, from proximal to distal.
