Figure 12 is a cross :section online |2|2 of My invention rel-ates to new and useful ,improvements in suction tonsillectomes and has for its primary object to provide an effective device which will enable a surgeon to enucleate a patients tonsils safely and with as Vlittle inconvenience as possible to the patient and to the surgeon. Another object of my invention is to provide a simple, rsmall and practical instrument vwhich is 1o so constructed that it may be operated entirely by one hand, thereby leaving the-operators other hand -free to assist him in .doing other necessary things.

A further object of the invention is to provi-de 15 an instrument which may be 'used lby either a right-hand or a left-hand operator.

A further object is to provide an instrument of the kind specied whichcombi-nes in oneoompact structure .the itonsil snare mechanism and 20 a suction mechanism for holding the tonsil in the instrument while the tonsil is being removed; also to provide the instrument Withaf swivelthumb yeye and with -a suction controlling valve that can be operated bythe thumb While the thumb is in thek 25 eye and While `the index and second fingers of the hand are being `used to operate the snare.

Other objects will in part beobvious and lin part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends `the invention still further resides yin the novel `details of construction,combination and arrangement of parts., all of -Whichwill befi-rst fully described in the followingfdetailed `*description and then be particularly pointed out in the appended 35 claims, reference being had to the accompanying drawings, in Which:-

Figure ,11i :is .an enlarged longitudinal ksection-of the .air-valve.

Figure A15 isa `crosssection on the line `|5|li of Figure AIn the-drawings in which like numerals of reference indicate like parts in all of thegures, v| is an elongated cannula body yhaving .a tonsil-receiving loop 2 at one end which is Iprovided with a'snarereceiving Vgroove 3. The body .I is bored at 4 -for the reception of vthe snare-operating rod l2, the bore extending :from the -loop i2 to a :transverse slot 5 in the lbody I. A :sliding block 'or cross head Goperates intheslot 5 and .projectstoieither side .ofthebody :I where it is'provided Withnger holes The zblock .6. isv .dove-tailed at 8 :so as `to t the body I and prevent lateral displacement of the block. As twill .appear most clearly in Figure 11, the block 6 jhas .a recess 9 to receive the head :and a recess I'qto ,receive the .adjacent portion :of the :rod |12.

v.At .its frontend the rod -.|.-2 has :grooves -I3 in its side and cross holes I4 to receive :the ends of the snare |5, the snare I5 being a exible, resilient, iine Wire.

The loop 2 has a recess I6 to receive the -flange |'8 of the cup Il 'the'lcup -being -composed of glass or other .suitable transparent material. It is formed with a suction nozzle |-9 whose'passage 2,0 registers with the-port 22 at the forward 7end `oif the suction duct 2| that ypasses longitudinally through the .body fl -toadjacent its rear end. At the rear end of the duct 2| the body is provided with a bore 23 for the valve 25 which controls the suction in the -duct'2|. The body I at the bore 23 is provided with a nipple 24 to which a suction line from a suitable vacuum pump, or other suction source, may be connected. The valve 25 has a port 3| to effect communication with the duct 2| when the valve is pressed in against the tension of the spring that is housed in the collar 28 which is welded, or otherwise secured, to the body The movement of the valve is limited by a pin 21 and slot 26 connection.

32 is the coupling member which, as will best appear from Figures 3 and 4, is provided with recesses 33 to receive the end of the body .to which it is secured by a screw 34. The coupling 32 has a swivel stub 35 that is riveted over in the swivel bearing 31 of the thumb eye 36. The cup Il is held in place by cement or other suitable means.

From the foregoing it will be seen that to use the instrument the thumb is thrust through the loop or eye 36 so that the ball of the thumb rests well over the head 29 of the valve 25. The index and second iingers are placed in the loops 1 respectively of the sliding block 6 and by pulling with the ngers in the loops 1 the block 6 will slide toward the thumb eye 36, pulling the rod I2 backward and drawing the snare I5 into the small hole occupied by the rod I2. It should, of course, be understood that before the snare is dravvn in the instrument is placed over the tonsil and the valve 25 is moved to cause suction to draw the tonsil well into the cup I1. Pulling back the rod I2 as above described produces astrangulation or cutting eect upon the 'tonsil which is surrounded by the snare. As soon as the snare has been drawn in and the tonsil severed the instrument may be removed from the patients throat and mouth and, by allowing the valve 25 to close, the suction is cut off and the severed tonsil may be removed from the cup.

As the entrance to the port or duct 20 is located at the upper portion of the cup the suction tends to draw in a direction along the axis of the tonsil rather than in a lateral direction, as would be the case if the port were at the base of the cup. 'Ihis action pulls the tonsil well into the cup and the inside contour of Vthe cup is such that once the tonsil is inside it will be somewhat gripped in the small opening to the port 20 and held securely in the cup.

The instrument may be used with either the right hand or the left hand as the surgeon may desire. It should also be understood that the rod I2 is made to t the bore 4 air-tight so that suicient suction can be established in the cup I1 and the loop 2 at the beginning of the operation to insure the tonsil being drawn up into the cup.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the complete construction, arrangement, operation and advantages of my invention will be clear to those skilled in the art to which it appertains. What I claim is:

l. A tonsillectome comprising an elongated body having at one end a tonsil-passing loop, a cup held on said loop to receive the tonsil, means operable in said body for severing the tonsil, said body and cup containing a suction duct, a suction valve in said body to control said duct, and a thumb-engaging member at the other end of said body, said means including an operating member having finger-engaging portions, said operating member, said valve and said thumb-engaging member being located in positions permitting simultaneous operation in virtue of which the instrument may be operated by one hand.

2. A tonsillectome comprising an elongated body having at one end -a tonsil-passing loop and at the other end a swivel thumb eye, said body having a transverse slot, a cross-head mounted on said slot and having finger openings, said body having a bore extending from said slot to said loop, a rod in said bore, and having a connection to said cross-head, an end of said rod being projectable linto said loop, a snare in said loop and connected to said end of said rod, a tonsil-receiving cup mounted on said loop, said cup and said body containing a suction duct, a suction valve carried by said body to control passage through said suction duct, said cross-head, said valve and said eye being located in cooperative position for actuation by one hand.

3. A tonsillectome comprising an elongated bodyl having at one end a tonsil-passing loop and at the other end a swivel thumb eye, said body having a transverse slot, a cross-head mounted on said slot and having iinger openings, said body having a bore extending from said slot to said loop, a rod in said bore, and having a connection to said cross-head, an end of said rod being projectable into said loop, a snare in said loop and connected to said end 'of said rod, a tonsil-receiving cup mounted on said loop, said cup and said body containing a suction duct, a suction valve carried by said body to control passage through said suction duct, said connection comprising a head on said rod and a recess in said cross-head to receive said rodhead and the adjacent portion of said rod. 4. A tonsillectome comprising an elongated body having at one end a tonsil-passing loop, a cup held on said loop to receive the tonsil, means operable in said body for severing the tonsil, said body and cup containing a suction duct, .a suction valve in said body to control said duct, and a thumb-engaging member at the other end of said body, said means including an operating member having nger-engaging portions, the entrance to said suction duct Within the cup being located at the crown of the cup in virtue of which the suction tends to draw in a direction along the axis of the tonsil.
