TONGUE DEPRES SOR Filed Jan. 7, 1948 .La, wham Patented Sept. 20, 1949 Jl ll'l'ED STATES PATENT OFFICE TONGUE DEPRESSOR Charles R. Lanahan, Hot Springs, Ark. Application January 7, 1948, Serial N6. 913 1 claim. (01. 128-15) (Granted under the act of March 3, 1883, as
The invention described hereinmay be manufactured and used by or for the Government for governmental purposes, without payment to me of any royalty thereon.
In ear, nose, and throat surgery, considerable diificulty may be experienced in retaining the tongue in position so that it will not form a pharyngeal obstruction during the course of the surgery. The usual type of tongue depressors do not obviate this danger, which is particularly serious where the patients are children. When such obstruction occurs, as when the patient swallows his tongue, only very prompt action on the part of the surgeon will obviate suffocation. The obstruction is due largely to the complete relaxation of the oral and throat muscles from anaesthesia.
The usual type of tongue depressors is essentially only a flat spatula, which may be provided with a handle for facilitating manipulation thereof, but which does not enable an operator to manipulate the tongue to any essential extent, with the aforesaid danger of obstruction resulting.
The present invention provides an improved tongue depressor which obviates the above-mentioned danger, and which permits the tongue to be lifted forwardly and maintained thus during the course of the surgery, or manipulated otherwise for maintaining the tongue in desired unobstructing position, the improved depressor of this invention providing a completely open airway during tonsillectornies and adenoidectomies and other surgeries f the mouth, nose, and throat.
Generally speaking, the tongue depressor of the present invention comprises a flat, hollow spatula portion for application to the tongue, the spatula portion communicating with a tubular handle, and having a relatively large aperture and the handle being adapted to be connected to a source of suction, whereby suction may be applied to the tongue to hold the tongue against the depressor. An aperture is provided in the handle for regulating the amount of $110- tion by closing and opening the aperture by application of the operators thumb.
The invention will be understood more readily by reference to the accompanying drawings wherein Fig. 1 is a side elevation, partially in section, showing the improved depressor in use;
Fig. 2 is an axial sectional elevation of the improved tongue depressor of this invention;
amended April 30, 1928; 370 O. G. 757) Fig. 3 is a front elevation of the improved depressor;
Fig.4 is a fragmentary perspective View showing the suction means for the tongue;
Fig. 5 is a transverse sectional view taken on the lin V-V of Fig. 2, l0oking in the direction of the arrows.
Referring more particularly to the drawings, the improved tongue depress-or of the present invention is composed of a substantially flat, hollow, tongue-engaging portion 1 opening into a tubular handle 9 that is provided at a convenient location with an opening II for controlling suction applied to the depressor through tube l3 attached to end [5 of the handle 9, the source of suction to which the tube 13 is attached being not shown.
The tongue-engaging portion 1 is provided with an enlarged aperture ll adjacent to its outer end, which is adapted to be inserted in the mouth of the patient. The aperture I! is enlarged at its inner tongue-engaging portion H which engages the back part of the tongue, and tapers as shown at I!) to conform generally to the configuration of the tongue. A sealing flange 2i surrounds the aperture l1, so that when suction is applied through handle 9, the area, of the tongue enclosed by the aperture I! will be sucked up into the opening, the flange 2! sealing the contact between the tongue and depressor portion I. The depressor portion l thereby forms a suction cup for enabling manipulation and retention of the tongue in any desired position. The opening H is provided at a convenient location for the operator to hold the instrument while controlling the opening II with his thumb for regulating the amount of suction applied to the tongue. It will be observed also that the tongueengaging depressor portion 1 and the handle 9 are at approximately right angles for facilitating the manipulation of the instrument. It will be apparent that, with the proper degree of suction, the tongue is brought into intimate and sealed engagement with the depressor portion of the instrument, and, consequently, the tongue can be held firmly in any desired position, without any tendency to drop back to form a pharyngeal obstruction with attendant danger of sufiocation to the patient.
Any suitable source of suction may be utilized; for example, if no other source of suction is available, a spring-actuated plunger and a suitable valve can be installed in the handle 9 in an obvious manner that requires no illustration.
It will be apparent from the foregoing that the implement of the present invention may be varied in structural details without departing from the inventive concept; and accordingly it will be understood that it is intended and desired to embrace within the scope of this invention such modifications and changes that may be required toadapt it to varying conditions and uses, as defined by the appended claim.
What is claimed is:
A suction tongue depressor for use in oral and nasal surgery, which comprises a substantially flat tubular tongue-depressor portion, a tubular handle portion disposed at approximately right angles to the tongue-depressor portion for ready application of the tongue-depressor portion to the tongue-depressor portion, means for connecting the handle portion to a source of suction, a sealing flange surrounding the opening to prevent entry of air between the opening and the tongue responsively to application of suction to the opening, and means in the handle portion for enabling control of the amount of suction at the suction opening, the suction opening defining a suction cup for retaining the tongue against the depressor portion for enabling manipulation and l holding of the tongue in any desired position.
a tongue to be manipulated, the depressor portion and handle portion having a continuous air passage therethrough, the depressor portion being provided with an inwardly directed and expanded tongue-engaging end provided with a suction opening substantially coextensive with the area of the expanded tongue-engaging end for engaging a' substantial area, of the tongue, the said suction opening being on the underside of CHARLES R. LANAHAN.
