SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed January 14, 1918. Serial No. 211,859.

To all whom it may concern.

' Be it known that I, FRANK BOHN, a citizen of the United. States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Surgical Instruments, of which the following is. a specification.

y inventlon relates to surgical instruments, and more particularly to such a device adapted for insertion within the nose to cut and remove portionsof bone, cartilage, or. the like, while not necessarily restricted to this use. 7

An important object of the invention is to provide instruments of the above'mentioned character, embodying a cutting element which is removable, thereby allowing of the use of. any number of cutting elements, of different shapes and sizes. 7

A further object of the invention is to provide an instrument of the above mentioned character, so constructed that the cutting element is operated positively and powerfully, to cut and remove the bone, cartilage or the like. v

Other objects and advantages of the invention will be apparent during the course numerals are employed. to designate like of the following description.

In the accompanying drawing, forming a part of this specification, and in which like parts throughout the same,

Figure 1 is a side elevation of an instrument embodying my invention,

Fig. 2 is a central longitudinal sectional view through the same, in elevation,

Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2, Fig. 4 is a similar view taken on line H of Fig. 2,

Fig. 5 is a similar view taken on l1ne 5-5 of Fig; 2, and

Fig. 6 is a similar view taken on line 66 of Fig. 2. p In the drawings, wherein for the purpose A of illustration is shown a preferred embodiment of my invention, the numeral 10 desigparts being shown nates the tubular body portion of the instrument, which is preferably circular in cross-section throughout the greater portlon of its length, as shown. At its forward end,

this tubular body portion is preferably flattened, providing an elliptical forward end portion 11, for a purpose to'be described.

Formed upon the rearend of the tubular body portion are pairs of apertured ears or knuckles 12, preferably integral therewith. These pairs of knuckles are disposed in the plane of the elliptical portion 11.

Extending rearwardly from the knuckles 12 are extensions 13, adapted to serve as stops, for handles or hand grips, to; be described.

The numeral 14 designates a pair of handles or hand grips, preferably longitudinally curved, and provided at their forward ends with enlargements 15, having recesses 16 formed therein, providing spaced ears or knuckles 17. The enlargements 15 are provided with reduced forwardly projecting extensions 18, extending between the cars 12, and pivoted thereto by pins or -pintles 19, as shown.

The numeral 20 designates an operating element, provided with a longitudinally extending screw-threaded opening 21. The operating element is provided at its forward end with pairs ofspaced ears or knuckles 22, receiving links 23, pivoted thereto, as shown at 24. The forward end of these links project into the recesses 16, and are pivoted to the ears 17, as shown at 25. The links 23 and associated elements constitute a toggle joint to move the operating element longitudinally, as is obvious.

Mounted to reciprocate within the tubular body portion 10 is a rod 26, the rear end of which is screw-threaded, as shown at 27, for insertion within the screw-threaded opening 21. The forward end of the rod is suitably tempered to render it resilient, and this forward end is provided with a longitudinal opening formed therein, providing spaced resilient arms 28. These arms carry oppositely arranged jaws 29, having rear cam surfaces 30. The cam surfaces 30, as more clearly'shown in Fig. 4, operate within the elliptical portion 11, and when the rod 26 is moved rearwardly, such cam surfaces will function to move the jaws 29 toward each other. The cam surfaces 30, operating within'the elliptical portion 11, prevent improper rotation of the rod 26.

The rod 26 may be readily removed by turning the same in the proper direction, whereby its screw-threaded end 27 is re moved from the opening 21.

While I have shown the jaws 29 curved in cross-section, as illustrated in Fig. 6, for providing longitudinal cutting edges, it is to be understood that. the invention is not r!) In threaded opening restricted to this particular type of cutter, asl contemplate employing cutters of different shapes and sizes, an for this reason the rod 26 is made removable, as above indicated.

A particular advantage of my construction is that when the rod 26. is moved rearwardly through the tubular body portion 10, in inserting a new cutting element upon contacting with the operating element 20, the rod at once shifts the operating element 20 to the central position, in alinement with the rod 26, whereby the screw-threaded end of the rod will properly enter the screw- In the operation of the instrument, the spaced resilient arms 28 urge the cam surfaces outwardly, which in turn cause the rod 26 to move forwardly, thereby retaining the several parts in the expanded position, as clearly shown in Fig. 1. The forward end of the tubular body portion 10 may now be inserted within the nose, and the jaws 29 brought into contact withthe bone, cartilage or the like, to be out. When the handles 14: are pressed inwardly, as indicated in Fig. 2, the rod 26 is moved rearwardly, and cam surfaces 30 coact with the extension 11, and force jaws 29 toward each other. These jaws have cutting edges extending around their longitudinal edges and forward ends, and the bone or the like is thereby cut.

it is to be understood that. the form of my invention herewith shown and described is nearest to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

An instrument of the character described, comprising a tubular body portion provided at its forward end with a portion which is approximately elliptical in cross-section, a rod mounted. to reciprocate within the tubular body portion and adapted to be removed therefrom and having its rear end screw- -threaded, resilient arms carried by the forward end of the rod and provided with oppositely arranged jaws having cutting edges, said jaws being provided upon their outer sides with cam faces to contact with the forward portion of the tubular body portion which is approximately elliptical in crosssection, handles pivoted to the rear end of the tubular body portion, an operating element having a screw-threaded openin to receive the rear screw-threaded end of 51 and links pivotally connecting the operating element and handles.

in testimony whereof I aflix my signature in presence of two witnesses.

FRANK BOHN.
