JOHN SKLAR, OF BROOKLYN, NEW YORK.

TONSILOTOME.

Speccaton of Letters Patent.

Patented Oct. 25, 1921.

Application led August 5, 1920. Serial No. 401,295.

r To all fw 7mm t may concern Be it known that I, JOHN SKLAR, a citizen of the United States, residing at New York city, borough of Brooklyn, State of New York, have invented new and useful Improvements in Tonsilotomes, of which the following is a specification.

This invention relates essentially to a device for cutting tonsils and it includes means for readily operating theV cutter.

The invention is designed to provide means controlled by the operator for rapidly moving the cutter to its initial position after it has cut the follicles projecting into the throat.

An object of the invention is to provide the rack pawl with a releasing device which simultaneously forces the cutter forward to be ready for the next operation.

Another object of the invention is to provide means for connecting the ends of the wire cutter so that it can be easily removed when desired and at the same time securely locked to the cutter carrying slide.

The novel features of the invention are more fully described in the following specication and claims, and illustrated in the accompanying drawing, in which Figure 1 represents a side elevation of an instrument embodying this invention.

Fig. 2 is a plan view of the forward portion of Fig. 1.

Fig. 3 is a vertical longitudinal section of Fig. 1.

Fig. 4 is a detailed horizontal section on a larger scale showing the method of connecting the cutter.

Fig. 5 is a plan view of the rear portion of Fig-1.

In the drawing, the numeral 6 designates a holder having a handle 7 projecting from its lower portion. On the forward end of the holder is arranged a grooved tubular guide 8 having an opening 9 at its front end. The guide is preferably mounted on the holder by means of a coupling consisting of a spring pressed locking ring 10, normally forced into engagement with an annular groove 11 located in the stem of the guide. By means of this arrangement the guide can be removed by pushing the ring out of engagement with the groove and a guide with dierent sized opening can be substituted.

The holder is provided with a longitudinal slot 12 adjacent to a bore 13 and it has ratchet teeth 14 located on the upper parallel rim portions of the slot. A slide 15 is fitted into the slot and it has a tubular stem 16 slldingly mounted in the bore of the holder. A spring pawl 17 attached at 18 to a stud fixed on the slide enages the teeth of the rack.

The tubular stem of the slide loosely carries a rod 19 having a threaded end made to engage the threads of a finger cap push button 20 screwed on the end of the rod. T he front end of the rod has a transverse pin 21 normally supported on the parallel rims of the slide and normally positioned 1n a recess in the spring pawl.

By pushing the linger button it compresses the spring 22 moving the rod forward and the pin rides out of the recess along the top of the rim to lift the spring pawl out of engagement with the teeth of the ratchet. In order to move the slide from its forward to its rearward position when the pawl engages the teeth of the ratchet a grip 24 for the fingers secured to the bottom of the slide is provided.

At the front end of the slide projects a threaded stem 25 having a tongue 26 with a pair of apertures as indicated in Fig. 4. A cutter 27 preferably made of thin steel wire suitably bowed is attached to the tongue by hooking the ends of the wire through the apertures. A sleeve 28 with an interior thread to engage the threads of the stem prevents the ends of the cutter from being unhooked while covered by a portion of the sleeve. When it is desired to detach the cutter the sleeve is screwed backward uncovering the apertures so that the ends of the wire can be easily straightened and drawn out of the apertures. The bowed or looped portion of the cutter normally fits into the groove or channel of the opening 8 and the parallel portions of the wire are guided in the tubular stem to the tongue.

When it is desired to bring the cutter into action the handle 7 is gripped by the hand and thumb and the other fingers utilized to draw the grip 24 toward `the handle. The slide and the cutter thus move with the grip and the pawl clicks over the teeth of the rack until the knife has severed the object. In order to quickly get the cutter back to its normal position as indicated, in Fig. 1, the handle 7 is grasped and the push button cap is pressed to move the spring pawl out of engagement with the teeth. The pressure on the button is at the same time transmitted to the slide which y is propelled forward to place the cutter in position for the next operation. A device consisting of a capstan sereT 30 arranged on the tubular stem of the slide can/be used to actuate the slide When greater leverage is required to cut any tough substance.

I claim:

l. A tonsilotome comprising a holder having a rack, a cutter carrying slide with a pawl engaging the rack, and means connected -to the slide for moving the paivl out of action to actuate the slide.

2. A tonsilotome comprising a holder ha"- ing a rack, a cutter carrying slide With a pavvl engaging the rack, and a push button mounted on the slide for moving the pavvl out of action to simultaneously actuate the slide.

3. A tonsilotome comprising a holder having a rack, a cutter carrying slide with a pawl engaging the rack, a tubular stem projecting from the slide, a rod arranged in the stem coacting with the paWl, and a push button cap connected to the rod for moving the pavvl out of action and simultaneously operate the slide.

4. In a tonsilotome the combination with a holder having aslideyof a tongue having apertures carried by the slide7 a Wire cutter, having its ends hooked into V the apertures,

' and means mounted on the tongue covering the apertures for locking the ends of the Wire.

5. In a tonsilotome the combinationy With a holder having a slide, of aV tongue with apertures projecting from the slide, a Wire cutter having' its ends hooked into the apertures, and a sleeve adjustably mounted on the tongue covering the apertures to prevent the hooked ends from being drawn out of the apertures. i

In testimony whereof I have hereunto set myhand in the presence of tvvo subscribing Witnesses. V y
