## Abstract

This invention is related to a laryngoscope used in endoscopic surgery of the larynx. The laryngoscope (1) which is the subject of this invention includes; a body (2) which is cylinder in shape and empty inside with one end placed inside the larynx, at least one handle (6) fixed with one tip to the other end of the body (2) and at least one sleeve (7) which is fixed to the other end of the handle (6) unconnected to the body (2) and facilitates the motion of the body (2). The body (2) includes; at least a canal (3)upon which the intubation tube is placed; a ridge (4)preventing the slippage of the intubation tube within the larynx; and at least two burrows (5) located on its end attached to the handle (6).

## Claims

### Claim at position 1

1-6. (canceled)

### Claim 7

A laryngoscope comprising: a body in cylinder shape with empty inside with the tip adapted to be placed within the larynx; at least one handle fixed with one tip to the other end of the body; at least one sleeve which is fixed to the other end of the handle unconnected to the body and facilitates the motion of the body; at least one canal which runs along the outer wall of the body starting from its tip placed within the larynx towards its end having the handle and upon which the intubation tube is placed; a ridge running along the outer side of the canal and preventing the slippage of the intubation tube within the larynx; and at least two burrows located on its end attached to the handle and being adapted for placement of a light source and aspiration cannula within.

### Claim 8 (depends on 7)

The laryngoscope of claim 7 wherein the canal is as large as a portion of the surface of an intubation tube can lie upon; and wherein the canal can be located on the left, right or midline of the lateral wall of the body depending on usage.

### Claim 9 (depends on 7)

The laryngoscope of claim 7 wherein the canal is semicircular in shape.

### Claim 10 (depends on 8)

The laryngoscope of claim 8 wherein the canal is semicircular in shape

### Claim 11 (depends on 7)

The laryngoscope of claim 7 further comprising a ridge wherein the ridge runs along the canal and the ridge is as long as the canal.

### Claim 12 (depends on 8)

The laryngoscope of claim 8 further comprising a ridge wherein the ridge runs along the canal and the ridge is as long as the canal.

### Claim 13 (depends on 9)

The laryngoscope of claim 9 further comprising a ridge wherein the ridge runs along the canal and the ridge is as long as the canal.

### Claim 14 (depends on 10)

The laryngoscope of claim 10 further comprising a ridge wherein the ridge runs along the canal and the ridge is as long as the canal.

### Claim 15 (depends on 11, 12, 13, 14)

A laryngoscope of any claims 11 to 14 wherein the most superior end of the ridge is on a level with the most superior end of the body placed within the larynx.

### Claim 16 (depends on 11, 12, 13, 14)

A laryngoscope of any claims 11 to 14 wherein the ridge fixes the laryngeal part of the intubation tube placed within the canal and which prevents the slippage of the intubation tube from over the body.
