VACUUM TONS ILLECTOME Filed July 5, 1932 mferw/bo l du/afd ijf m 8 Claims'.
The invention relates to improvements in Vacuum tonsillectomes and more particularly to an improved structure and adjustable mounting for the tonsil receiving cup. v
An object of the invention is to provide'an effective device to facilitate a thorough enucleation of a patients tonsil with the capsule intact, without unnecessary injury to or excessive bleeding by the patient.
Another object is to provide an improved instrument of the character described which is well balanced-and easy to manipulate, thus giving a maximum eiciency, and readily adjusted to different positions to the convenience of the operator, permitting use of one hand leaving the other hand free.
Another object is to provide a slidable and pivotal mounting for the tonsil receiving cup whereby said cup may be adjusted relative to the loop or snare associated therewith and improved means to adjust the position of said cup and retain it adjusted. 0 f
The kforegoing and such other objects of the invention as will appear hereinafter as the description proceeds will be more readily understood from a perusal of the following specification, reference being had to the accompanying drawing', in which:
Fig. 1 is a lside elevational View of the improved vacuum tonsillectome.
Fig. 2 is an enlarged longitudinal sectional View of the tonsillectome. Y
Fig. 3 isa vertical transverse sectional view taken on line 3-3 of Fig. 2.
rIhe'instrument described is adapted for use to remove tonsils, the operation being made extremely simple and safe in that almost no blood is lost by the patient and the enucleation thereof is quickly accomplished and thorough. As shown in the accompanying drawing, the improved instrument preferably embodies a sleeve 11, preferably substantially square in cross section, of the known type having a finger ring or grip 12 at one end and suitable means (not ishown) at its other end to receive detachably one end of a cannula 13. slidable Within the cannula is a stem 14, preferably of heavy Wire, having a fine Wire loop or snare 15 at one end extending normally beyond the free end of the cannula. The other end of the wire 14 is attached to a collar 16 slidable on sleeve 11, said collar having finger rings or grips 17 adapted to be engaged to move the collar toward the grip 12 on the sleeve 11 and draw the snare 15 into the cannula 13 for a purpose to be described later.
PATENT OFFICE 1,931,740 VACUUM ToNsILLECToME Edward S'Ryan, Sheboygan, Wis. l i Application July 5, 1932.L serial No. 620,762
(Cl. 12S-309) A bracket 18 consisting of a square tubular body 19 and spaced longitudinal flanges 21 is slidably mounted on cannula 13.
A tonsil receiving cup`22r, including a tubular stem 23, has spaced ears 24 thereon pivotally connected with flanges 21 by a pin 25 whereby said cup may be moved toward and awayfrom the plane of the snare as shown in full and dotted'v lines in Fig. 2. Pivotal and longitudinal adjustment of said cup relative to the snare is necessary to facilitate Working of the tonsil to be remo-vedinto the cup."
In operation the snare 15 is slipped about the tonsil and the tonsil is then worked into the cup with the ngers of one hand, the operator holding the instrument with the other hand by means of loops 12 and 17. While the .tonsil is being pres/sed into the cup said cup is moved, in a manner to be described, toward the snare until the cup completely embraces the tonsil leaving only the base exposed. The finger grips are then squeezed to move the collar Y16 toward the loop 12 and the snare, upon being drawn into the cannula, completely enucleates the tonsil. Asit is desirable. to collect' the blood and secretions in the cup 22 it is necessary to produce a rarecation of air therein and to this end the stem 23 of the cup is connected with a suitable vacuum pump (not shown) by a flexible tube 26.
Adjustment of the cup relative to the plane of the snare preferably is accomplished by manipulation of means operable-by the same hand holding the instrument. This is desirable since such a structure leaves the other hand free to press and hold the tonsil in the cup while said cup is being moved into position and during enucleation.
As shown the ears 24 on the stem 23 preferably extend rearwardly of the bearing pin 25 and carry therein a rotatable pin 27 having a triggelg'comprising parts 28-29, fixed thereon. The part 28 of said trigger is arcuate and has teeth 31 adapted to cooperate with serrations 32 on the Abody 19A of sleeve 18 and the other trigger portion 29 provides a iinger piece which extends to within reach of the hand holding the instrument. A spring 33 normally holds the teeth 31 lno sie"
obtainable with this structure, as reflected in the work accomplished thereby, is far superior to that obtained with other known devices since complete insertion of the tonsil into the cup is readily accomplished, and clean enucleation is possible. With prior devices, because of the difculty encountered in working the entire tonsil into the cup, fragments of the tonsil very often remain necessitating, for their removal, further operation with a knife, with increased injury and discomfort to as well as loss of blood by the patient.
Although an exemplary embodiment of the improved tonsillec'tome is disclosed in the accompanying drawing and described in detail herein, it is to be understood that the instrument may embody such modifications and variations as vwill fall within 'the spirit of the invention and the scope of the appended claims.
