ERDWN Patented Apr. 26, 1938 2,115,298 UNITED I STATES PATE NT OFFICE 2,115,298 ' SUCTION TONSILLECTOME . Roderick F. Brown, Altus, Okla. . Application April 16, 6 Claims. My invention relates to certain new and useful improvements in suction tonsillectomes and it has for its primary object to provide an instrument of such compact construction and perfect cor 5 relation of parts that an operator may remove a patient’s tonsils with the greatest possible skill and safety, having at the same time in his control all equipment necessary for the operation. Further the invention has for an object to pro vide an instrument which enables the operator, with a single instrument and the use of one hand only, to draw the tonsil from its capsule or rest ing place in the throat to‘ such position that it may be severed, the tonsil remaining at all times 15 in plain sight of the operator and, ‘due to the special construction of the instrument enable a practically bloodless operation (no bleeding of the tonsil or any part of the throat occurs until the tonsil is actually severed). Other objects will in part be obvious and in 20 part generally pointed out hereinafter. 1937, Serial No. 137,347 ‘ (Cl. 128-309) The end of the air duct 2, opposite the bowl 3 is provided with a seat 2? to receive the nipple ‘I of an air suction hoseG which hose attaches to a pump or other suitable means to provide a suction (not shown). The part of the nipple ‘I I‘ which'inserts into duct 2 is tapered so as to make a friction-tight connection. It should be borne in mind that this method of attaching the instru ment to the vacuumjpump is perhaps the most 7 simple and convenient,'yet' any other form of '1 nipple and ?exible‘ conduit: may be employed in the successful operation [of the instrument. Atv such a position along the'course of the‘ air duct 2, as is mostlconlvenient to the operator, _ is placed the valve 8. This valve is intended to be " 15 operated with the index ?nger, although other positions may be found’ more convenient for dif ferent operators. Therefore the exact location of valve 8 is not considered to be a feature of this invention. The valve 8 is what is commonly 20 called arplug valve; it may be either tapered or To the attainment of the aforesaid objects and ends, the invention still further resides in those novel details of construction, combination and. arrangement of parts, all of which will be ?rst straight-bodied.’v The plug passes through the ing in which, valve is turned to one position or another. body I laterally and intersects the passage or duct 2. It has a bore I0 of approximately the same diameter as the duct 2,‘ and it is provided with fully described in the following detailed descrip a handle 9 by means of which the valve may be tion, then be pointed out in the appended claims, turned to align thebore ID with duct 2 or close reference being had-to the accompanying draw voif the passage more or less, accordingly as the Fig. 1 is a vertical longitudinal section of the instrument. ' , Fig. 2 is an assembly of the cutting members of the instrument the view being an inverted plan view of the parts mentioned. a Fig. 3 is a bottom or inverted plan view of the tonsil bowl or cup. Fig. 4 is a detail plan view of a portion of the instrument showing the valve. In the drawing in which like numerals of ref 40 erence indicate like parts in all the ?gures, I denotes the elongated body of the instrument. This entire piece may be constructed of glass or other transparent material, such as “bake-lite” for example or it may be made of metal, using a 4 transparent element for the tip or tonsil bowl (see my Patent No. 2,036,998 issued April 4, 1936). The body I has a longitudinal air duct 2. One end of the duct 2 is enlarged to such dimensions and proportions as to form a bowl or cup 3, into which the tonsil is received. The cup is more fully shown in Fig. 3 in which the general con tour is outlined by reference numbers 3. A sheath 4 is formed on the body I connecting the cup 3 with a projection IX from the body. 55 The sheath is tubular to receive the snare post 5. . The sheath 4 is an integral part of the body I and is bored to receive the snare post 5, the snare post passing through a stul?ng box of which II is a packing of suitable material which is pressed into position by gland I2. By this means loss of vacuum is prevented. The snare post 5 is secured 35 to the ?nger-bar I3 in any approved way as, for example, by the “latch” arrangement shown in Figs. 1 and 2 at I4. The ?nger-bar I3 is secured to the body I by a bolt I 5 which passes between the- two loops I8 provided for the ?ngers. The under face I9'of the body I is ?at and the ?nger-bar I3 slides against such ?at surface I9, which prevents twisting the bar to'undesirable positions. The bolt I 5‘is threaded at I 5X into the body I and passes through an apertured. lug IY. ' The bolt I5 has a milled head I 6 by which it may be turned to screw it into the body at I5)‘. Beyond the head I 6 there is swivelly mounted 50 on ‘a projection of the bolt, a thumb loop I‘! (see Fig.1) . . The construction of the ?nger-bar I S and the snare 20 is most clearly'shown in Fig. 2 by ref erence to which it will be observed that the bar 2,116,298 l3 has two loops or eyes I8 into which the index and second ?ngers pass. The snare post 5 is connected to bar I3, at M, as before described. The end of the post 5 is ?attened on opposite sides and holes 2| are drilled through the ?at tened portions to receive the ends of the snare wire 20. Snare wire 20 is a ?ne gauge metal wire having enough spring quality that it will retain '10 a circular form when placed in the instrument. A groove 22 (see Figs. 1 and 3). is provided in the bowl 3 to receive the snare 20. Thus, due to the spring quality of the wire 20, it is held in air duct in connection with said bowl and hav ing provision for the connection of said duct to a suction line, a valve carried by said body to control passage through said duct, said body having a ?at underface, a ?nger-bar having ?nger loops and located in contact with said flat underface, means carried by said body beneath said ?at underface for slidably sustaining said ?nger-bar, a sheath carried by said body and extending rearwardly from said bowl parallelly, beneath said body and having a bore one’ end of which communicates with said bowl, a stuff groove 22 and allows the tonsil to pass into bowl 3. . ing box at the other end of said bore and a snare post held in said sheath and passing through said stu?‘lng box and being connected to said 15 15 In operation the instrument is ?rst made ready I ?nger-bar, said snare post adjacent said bowl for use in the following manner: Assuming the carrying a snare. 3. In a suction tonsillectome, a body having a instrument to be assembled except for the snare tonsil receiving bowl at one end and having an. wire 20 and the hose and nipple 6 and 1 respec airduct in connection with said bowl and hav 20 20 tively. The ?nger-bar l3'is exposing holes 2|. ing provision for the connection of said. duct to A piece of snare wire 20 of the proper length and Operation having the ends properly crimped to facilitate ' a suction line’, a valve carried by said body to con threading is attached to post 5 in the manner shown in Fig. 2. Finger-bar’ I3 is now pulled 25 back and adjusted to such a position that snare 20 is in its proper position in the groove 22; pack ing gland l2v is now tightened enough to insure against leakage. Hose nipple ‘l is inserted in air duct 2 and givena slight twist sothatit tightens in a position where the hose 6 willv hang in a natural and convenient position for the operator. The instrument is now held in the operating po sition, which is with the thumb extending ver tically thru thumb loop l1 and with the index and second ?ngers in loops Ill. The hose 6 should now be hanging so as to pass through the palm of the hand. . With the valve in the closed posi tion and the suction pump in operation, the in strument is passed into the patient’s throat which .40 has been properly prepared for the operation. With the ?ngers of his free hand on the outside of the patient’s throat the operatorpresses in the vicinity of the tonsil, thus assisting in rais ing the tonsil so that the cup 3 of the ‘instru . merit may be placed directly on the tonsil. When the instrument is properly placed over the tonsil the valve is opened and the tonsil allowed to be drawn into the'cup by the action of the pump. The operator can see the tonsil through the walls of the cup and can tell when the proper position is obtained to sever the tonsil, which is done by merely clinching the hand. From the foregoing description taken in con nection with the accompanying drawing it is thought the construction, operation and ad vantages of the invention will be clear to- those skilled in the art.
