Application led March, 19,17. Serial No. 152,564.

To aZZ whom t may concern:

Be it known that I, JACQUES .GREEN- BERGER, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a certain new Instrument, of which' specification.

My invention relates to surgical instruments, and is adapted more particularly to an" instrument for performing operations for removalof the tonsils, they soft palate `or other minute and readily accessible organs, or growths, such as adenoids and thelik'e.

The objects of my invention are minor operations to be performed in such a manner that a minimum ofhemorrhage will occur, and by means of which such hemorrhage as does occur will take place after the organs have been removed and the operation completed.

A further object is to provide means for placing the instrument in position, and securing it to the part of'the organ to be am-` putated before the cuttingoperation is commenced.

Another object is to provide means to facilitate the removal ,ofthe organs desired to be amputated, with a minimum expenditure of energy onthe physician, and minimizing the pain Vof the patient by enabling the operation to be perskill and despatch than now practised.

Another obj ect is-to -provide means for the ready removal ofthe severed organs.

These and further objects will more fully appear in the following-specification and accompanying dra-wings considered together.

or separately.

I have illustrated one embodiment of my invention in the accompanying drawings, in which like parts are designated by similar reference characters, and in which?- Figure 1 is a top plan view ofan instrument i embodying ymy invention Fig. 2 is a side elevationpartly in central longitudinal section;

Fig. 3 isa section on the line 8-3 of Fig. l;

Eig. 4 is a section on rthe line of Fig. l;

Fig. 5 is a section .on the ilineur-'S of Fig. 6 is a section Aon the line {6l-f6 of and useful Surgical the vfollowing is a i The slide is working in slots in the slide, and is held in part of the operating Fig. Y is Fig. 2; and

Fig. 8 is a detail sectional view of the slide accommodating a snare portion of the apparatus.

In carrying out my invention, I employ a been modified to a section on the line 7-7 of tonsilectome which has forma base or clamp for A snare may be detachably mounted on the clamp and movable relatively therewith; the saidsnare performing the cutting operation when desired. n

In the drawings,`A designates the modied snare, and B the baseor clamp formed of a modified 'tonsilectome The base `or clamp comprises a handle l by means of which it may be supported in position. The handle carries a base plate 2, the outer extremity 3 of which is of a spatula form with a U shaped rim 4, provided onthe inner surface with a groove or recess 5; the said spatula `having an'opening 6 therein.

A slide y7 is mounted on `the face of the base plate and is lmovable relatively thereto. guided by studs on the base Contact .with'the base by means of a spring member 8 carried by one of the studs. The front end 8a of the slide is flattened to tongue shape, and its forward edge is so rounded andshapedfso as not yto come into contact with the recess 5 at the front of the spatula, :but is so adjusted and limited in movement by the `action vof the spring member v8 as to prevent cutting the tonsil or other organ, but have a sufficient forward movementto securelyhold/in position the organ upon which the operation is to be performed. The `recessy 1,5 acts as a receptacle for sthe wire 16 when `it is desired Yto adjust the same preparatory'to performing the cuttingfoperation. The rear end ofthe slide is provided with .gripping means having an opening therein, by means of which it may be moved ,relatively to the ,base plate.

ySecured to the base plate is a U shaped guide9, the sides of whichextend above the slide 7. The inner portion of each side of the ,guide is provided with a groove l0.

being inclinedlrelativelyto the slide 7.- They able, asahereinafter described. The rearend side of the guide is proinclined face 1l and a carrying a snare.

Y portion lo,

"Sti

of the rod is provided with a screw threaded and its forward, reduced eX- tremity is provided with the usual means foi` attaching the wire loop 16, by means of which the cutting is accomplished. rlhe rear portion of the tube 13 is slotted for a considerable portion of its length on diametrically opposite sides, as at 1T, and iinger pieces 17a are secured to the rod 1i and project through the slots, and prevent rotation of the rod. rlhe forward end of the tube is flared, as at 1S, and is provided with teeth or prongs 19.

The tube 13 is provided with trunnions 20, which are adapted to engage the grooves 10 of the guide 9.

A. spring 21 carried by the stud lof the base plate engages the under side of the tube 13, and holds the snare in properan gular relation to the base plate.

A nut 23 engages the threaded portion of the rod, and a thumb piece 24C is provided at the rear end of the tube 13,Y the said thumb piece having a threaded portion so as to permit its removal for the purpose of enabling the removal ofthe tube 13 for cleaning or otherwise.

The operation is as follows:

rfhe slide 7 is moved to the rear until the opening 6 is disclosed. The snare er with the loop 16 attached to thek end of the rod le which projects al short distance from the forward end of the tube 13, is placed in position between the sides of the guide 9 with the trunnions 2O resting in the notches 1Q., and in line with the grooves 10. The spring 21 will retain the tube in position.y The loop 16, by its own flexibility,

is distended, and its forwardend vrests with-- in therecess 5.

The instrument is thenplaced in position with a tonsil, for example, projecting through the opening 6. Theslide 7 is now pushed forward and presses the neck of the tonsil against the base of the U shaped rim i.

The thumb piece '2e is pushed forward, which moves the tube 13 so as to draw the end of the rod into the tube, closing1 the loop of the wire 16, and withdrawing it from the recess 5, and engages the neclr of the tonsil rbetween thewire and the end of the tongue 8am The tube is pushed forward until that portion of the tonsil which is to be removed, is impaled upon the teeth or prongs 19 on the end of the tube. When the tube has reachedL this position, the trunnions 2O have traversed the entire length of the grooves 10, and the base or clamp B is automatically released from the snare er, leaving it attached to the tonsil and in proper position to sever the saine. No blood has been shed, and the entire operation has been plainly7 visible to the operator, and has been per- Leeenai formed without discomfort or pain to the patient.

lf it is desired to remove the other tonsil, the snare A is held in position by suitable means, or by an assistant. A new snare is placed in position on the base or clamp, and the above described operation is repeated.

llhen both tonsils are securely heldin the snares, the nut 23 is wound up on the threads 17, the rod is withdrawn farther intothe tube, drawing the loop 16 entirely within theV tube, and severing the tonsil which will remain impaled on the end of the tube by the prongs 19, so that there will be no danger of its dropping into the throat of the patient. The operation just described is performed with the utmost despatch, greater than now in practice, and with a corresponding benefit to the patient.

TWhen an assistant is present, the two tonsils may be removed simultaneously.

lVhile l have illustrated the teeth or prongs 19 as an integral part of the tube, they may be so constructed as to be independent thereof, and be so arranged as to be movable relative to the tube, so that the prongs will not protrudefromthe end of i the tube unless and until desired for use in the operation.

ln accordance with the provisions of the patent statute, l have described the principlc of my invention together with the apparatus which sent the best embodiment thereof, but I del now consider to repre-4 sire it understood that my invention is not confined to the particular form ofapparatus V. herein shown and described, and, therefore, f

l claim broadly .the right. to employ all equivalent instrumentalities coming `within the scope of the claims, and by'means of which objects of my invention are attained, and the new results accomplished, as herein set forth, as itis obvious that the `particular embodiment herein shown and described is only one of many that can be employed to attain these object-s and accomplish these results.
