SURGICAL INSTRUMENT.

Specication of Letters Patent.

Patented Nov. 2, M9039.,

Application filed January 2G, 1909. Serial No. 473,289.

To all 'whom it may concern:

vBe it known that l, donn Numan Korn, a citizen of the United States, residing at Fairfax, in the county ot Osage and State of Oklahoma, have invented new and useful improvements in Surgical Instruments, of which the following is a specification.

This invention appertains to surgical instruments for use by physicians, veterinarians and others to greatly facilitate the exploration of passages and cavities of the body when making examination to determine the condition or state thereof.

The invention has for its object to provide a device of this character which is so designed as to be comparatively simple and inexpensive to manufacture, readily applied or inserted and so designed as to edectively illuminate the parts to be examined.

Another object ot the invention is the provision of a device of this character which consists of an observation section of tubular form having an adjustable eye piece, in combination with a light or illuminating device including an electric bulb that is adapted to be connected in circuit with a dry or other battery by means of a push button.

With these objects in view and others, asv will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claim appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, Figure l is a longitudinal sectional view of the device with portions in elevation. Figs. 2 and 3 are transverse sections on lines 2-2 and 3 3, respectively.

Similar reference characters are employed to designate corresponding parts throughbut the views.

Referring to the drawing, A designates the tubular sight section of the device which is of suitable length to conveniently reach the parts to be observed, there being arranged on the outside of the device a scale divided into inches or other suitable units for determining the extent of penetration or insertion of the device into the cavity or passage to be examined. ln the other end of this tube is a telescopically arranged eye piece l in which is arranged a lens 2 disoutwardly for obtaining the proper focus.

In the other end of the tube is an objective t which cooperates with the lens 2 to magnify the parts to be examined. Arranged parallel with the tubular body A is a tube B of smallerdiameter which has its inner end flush with the objective carrying end of the tube A, and in the said inner end is arranged a bulls-eye lens 5. In the outer end of the tube B is an electric light bulb 6 behind which is positioned a reliector 7 whereby the rays of light are directed to and through the bulls-eye lens `which effectively illuminates the parts to be diagnosed. Secured to the tube A is a compartment C which includes a dry battery 8 which supplies current to the lamp, there being a push button 9 for connecting the lamp in circuit with the battery. The outer end of the battery has a removable cap l0 through which the battery can be inserted or removed. The tubular bodies A. and B are inclosed in a casing 1l which is perfectly smoothat all points so that the device can be positioned without tearing or lacerating a membrane.

in using the device, the objective end thereof is inserted in the cavity or passage to be examined, and when in proper position, the lamp is ignited by pressing the push button 9. The eye piece 5 is then adjusted to obtain the proper focus so that the physician or veterinarian can accurately diagnose the case.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appert-ains, and while I have described the principle of operation of the invention, together with the device which l now consider to be the best embodiment thereof, l desire to have it understood that the device shown is merely illustrative, and that suchl changes may be made when desired as are Within the scope of the claim appended hereto.

Having thus described the invention, what I claim is ln an instrument of the classY described,

the combination of a pair of tubular mem-i bers disposed side by side, a battery casing 2 eaeoee connected with the members, an electric In testimony whereof I aitix my signature lamp in one of the members, a sgitlchbfor vin presence of two Witnesses.

the outer end thereof, and a casing snr- H. N. COOK,
