Abstract

A tongue blade (retractor) with fenestrated suction ports along the length of the blade to remove (suction) smoke, fluid and/or particulate from the oral cavity during surgery (e.g. tonsillectomy, adenoidectomy, oral cavity/tongue/airway procedures). This blade can connect to routine mouth retractors and commonly available suction tubing. It has a groove along the length of the blade to accommodate endotracheal tubes for stabilization and to minimize pressure against the tongue during retraction.

Claims (26)

1 . A surgical retractor for evacuation of a surgical site, and which is connectable to a pneumatic evacuation device, comprising:

a tongue blade comprising a proximal end and a distal end,

a conduit associated with the tongue blade, wherein the conduit extends along the tongue blade in a tongue blade proximal end to tongue blade distal end direction, and the conduit comprising a row of apertures;

a receiving port that pneumatically communicates with said conduit; and

a handle comprising a distal end, a proximal end, wherein the distal end of the handle is connected to the proximal end of the tongue blade;

wherein the receiving port connects to the pneumatic evacuation device;

wherein the row of apertures are pneumatically connected to the pneumatic evacuation device by the receiving port; and

wherein the tongue blade defines a rearward concave space that serves as a channel for airway equipment.

2 . The retractor of claim 1 , wherein the conduit is integral to the tongue blade.

3 . The retractor of claim 1 , wherein the tongue blade has a length of about 60 mm to about 110 mm.

4 . The retractor of claim 1 , wherein the tongue blade has a width of about 20 mm to about 40 mm.

5 . The retractor of claim 1 , wherein the tongue blade is curved.

6 . The retractor of claim 1 , wherein the row of apertures comprises at least 2 apertures.

7 . The retractor of claim 1 , wherein the handle comprises a curved tip at the proximal end of the handle.

8 . The retractor of claim 1 , wherein the surgical retractor can evacuate liquid, aerosol, or airborne matter from a surgical site.

9 . The retractor of claim 1 , wherein the handle further comprises an attachment component for a surgical device.

10 . The retractor of claim 9 , wherein the surgical device comprises a second retractor or a mouthpiece.

11 . The retractor of claim 1 , wherein the receiving port is affixed to the conduit at an angle between about 90° and about 180°.

12 . A surgical retractor for evacuation of a surgical site, and which is connectable to a pneumatic evacuation device, comprising:

a tongue blade comprising a proximal end and a distal end,

a conduit associated with the tongue blade, wherein the conduit extends along the tongue blade in a tongue blade proximal end to tongue blade distal end direction;

a handle comprising a distal end, a proximal end, wherein the distal end of the handle is connected to the proximal end of the tongue blade; and

a mouthpiece connected to the handle via a mouthpiece attachment component; and

a receiving port that affixes to and pneumatically communicates with said conduit.

13 . The surgical retractor of claim 12 , wherein the conduit is a pneumatic tube comprising a row of apertures and a receiving port at the proximal end, wherein the tube is secured to the tongue blade by an attachment component on the tongue blade.

14 . The retractor of claim 13 , wherein the tube is comprised of a flexible or rigid material.
