U. 8. SMITH TONSILLECTOME May 24, 1932.

Filed Sept. 25, 1931 Inventor flllorney Patented May 24 1932 PATEN'B rice ULYssns soorr'rpsnrrrr, or HANNIBA MISSOURI TQNSILLEGIQME' Application filed September 25, 1931. serial No. 565,173.

The present invention relates generally to surgical instruments and more particularly to a tonsillectome and has for its primary objectto provide, in a manner as hereinafter ""45 set forth, an instrument of this character embodying a novel construction, combination and arrangement of parts through the medium ofawhich 'theftonsil is crushed off, thereby limiting hemorrhage resulting from the operation. v i

*Another important object of the invention is to provide a tonsillectome including a manually operable slidable snare of heavy wire and further including novel means for mounting the snare on its carrier.

"Another very important ob'ec't of the invention is to provide a tonsillectome embodying novel means for engagement by the digits of the hand formanipulating the instrument and controlling and actuating the same.

Other objects of the invention are to provide'a tonsillectome of the character 'described which will be simple in construction, strong, durable, eflicient and reliable in use and which may be manufactured at low cost. All ofthe foregoingandstill furtherob jects and advantages of the invention will become apparent from a study of the following specification, taken in connection-with the accompanying drawings wherein like characters of reference designate corresponding parts throughout 'theseveral; views, and wherein:- 7' l l Figurel is a top plan view of the tonsillectome constituting the present invention;

' is in use.

it Will be seen that the tonsillectome constituting the present invention comprises an elongated metallic bar 1 having a longitudi- At its inner end the slot 2 merges with a polygonal opening 3 pro- 55. vided in the bar 1. Formed integrally with the inner end of the bar 1 is a depending, arcuate finger 4; for abutting engagement with the ball portion of the hand adjacent the base of the thumb when the instrument Risingfrom the inner end portion of the bar 1 is an upwardly and rearwardly curved finger 5 for engagement be tweenthe base of the thumb and the base of the index finger when the. instrument is in'66 use. The base portion of the finger 5 is provided with alongitudinal opening 6 the purpose of which will be presently set forth.

On the outer end portion of the bar 1 is a guide 7 through which the snare to be previ sently described is operable. The outer end of the guide 7 is formed to-provide anarcuate jaw 8 for. cooperation withthe aforemen? tioned snare. All-of the surfaces of the jaw 8 are rounded so that no cutting edges are present. e p a l Disposed beneath the jaw 8 is a bowl 9 for the reception of the severed tonsil. A. web 10 bridges a lower portion of the slot 2 at an intermediate point in the bar 1. Rising from an intermediate portion of the bar 1 on op posite sides of the slot 2 are the posts 11, the purpose of which also will be presently set forth. 1 A carrier12 is operable.longitudinally in the slot 2, said carrier having its forward portion upwardly offset, as at 13, and'operable above the web 10. At its inner end the carrier has formed integrally thereon an upstanding head 14 having a longitudinal threaded opening 15 therein which is aligned with the opening 6. The head 14 is passed through the opening 3 when mounting the carrier 12 in position or When removing said carrier.

The reference numeral 16 designates a raised intermediate portion of the carrier 12. At its forward end the raised portion or rib 16 terminatesin a point andformed integrallythereon is a guard 17; The guard 17 is raised with respect to the bar 1 and is substantially of the configuration of an arrow head.

The reference numerals 18, 19 and 20 designate longitudinally spaced upstanding posts on the outer end portion of the carrier 12. The posts 19 and 20 are substantially T- shaped, as illustrated to advantage in Figure 5 of the drawings. The reference numeral 21 designates a snare of heavy wire which is bent to define a loop and'theend portions of which are engaged with the posts 18, 19 and 20 and the guard 17 in the manner best seen in Figure 3 of the drawings. The heads of the substantially T-shaped posts 19 and 20 prevent the wire from accidentally slipping off. The guard '17, in addition to retaining the free ends of the wire constituting the snare, also shields these ends to prevent injury by contact therewith. The snare 21 is thus mounted on the carrier 12 for reciprocation longitudinally in the guide 7 Extending from a rear portion of the carrier 12 is a finger 22 which constitutes the main means for actuating the carrier. tending upwardly from the carrier 12 at a point slightly forward of the finger 22 is a finger 23 which also is for engagement by a finger of the hand for actuating the carrier. A stop 24 rises from the carrier 12 in forwardly spaced relation to the finger 23.

The reference numeral 25 designates an auxiliary carrier operating device or member which includes a threaded shank 26 which is engagement in the opening 15 of the head 14 for operatively connecting said auxiliary actuator to the carrier. The actuator 25 .is provided with an enlargement defining a shoulder 27 which is engageable with the finger 5. The reference numeral 28 designates a handle in the form of an eye for actuating the member 25. A threaded shank 29 rises from a rear portion of the carrier 12 and has threaded thereon a nut 30. The nut 30 travels above the bar 1 and prevents downward movement of the rear end portion of the carrier 12 through the slot 2' when the instrument is in use. 5

When in use, the finger 4 is engaged with the ball portion of the hand adjacent the base of the thumb and the crotch portion of the hand which is between the. base of the to properlyengagethesnare 21 overthe tonsil. During this operation the disposition of the index finger between the stop 24 and the posts 11 will prevent accidental or unintentional actuation of the carrier 12 rearwardly. After the tonsil has been properly engaged, the index finger is removed from between the stop 24 and the posts 11, and, if desirable, or necessary, may be engaged with the upper portion of the finger 23 to assist in pulling the carrier rearward- The snare 21 co-acts with the arcuate aw 8to crush and then sever the tonsil. The construction of the device is such that the use of a comparatively large wire is permitted which is an important feature of the invention. This comparatively large wire forming the snare 21, in conjunction with the rounded surfaces, of the jaw 8 will result in first'crushing the tissue and then severing the tonsil, thus completing a substantially bloodless operation. 1

In those comparatively rare" cases where even greater power on the carrier12 is necessary or desirable and can be applied by engaging the fingers of the hand with the fingers 22 and 23, the shank 26 of the actuator 25 is inserted through the opening 6 and engaged in the threaded opening 15 of the head 1.4 on the carrier. .The actuator 25 is then rotated and, with the shoulder 27 abutting the finger 5 the carrier 12 will be, drawn rearwardly, as will be'apparent.

It is believed that the many advantages of a tonsillectome constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction, and in the combination'and arrangement of parts maybe resorted to which will fall within the scope of the invention asclaimed.

4. A tonsillectome comprising an elongated bar having a longitudinal slot therein, a jaw on one end of the bar, a carrier mounted on the bar and slidably operable in the slot, a snare mounted on one end of the carrier for'coaction with the aw, a head on the other end of the carrier having a threaded opening therein, an upstanding finger on the other end of the bar having an opening thereinin longitudinal alignment with the opening'in thehead, an actuator rotatably insertable through the second named opening for threaded engagement'with the head for actuating the carrier in one direction, and a shoulder on the actuator for abutting engagement with the finger.

In testimony whereof I affix my signature.
