SPECULUM.

SPECIFICATION forming part of Letters Patent No. 605,715, dated June 14, 1898.

Application filed December 4, 1897. Serial No. 660,795. (No model.)

To a/ZZ whom it may concern:

Be it known that I, KARL'HOHMANN, physician, a subject of the Emperor of Germany,

residing at Neukirchen, district of Ziegenhain, Germany, have invented certain4 new and useful Improvements in Surgical Instruments for Use in Intranasal Operations, of which the following is a specication.

My invention has reference to improvements in surgical instruments for use in intranasal operations; and it consists principally in a hook-shaped forkto draw up the nostrils and in a spring to distend the nostrils in a lateral direction, so as to afford the 0perator an unobstructed view into the nasal cavity and the largest possible opening for the introduction of his instruments.

In order to make my invention more easily understood, I have illustrated it in the accompanying drawings, in which- Figure 1 is a side view of the device for drawing up the nostrils. Fig. 2 is this instrument in position on the head of the person to be operated upon. Fig. 3 shows a front view of this device, while Figs. 4 and 5 show a front view and side view ofthe spring device.

A' hook-shaped double-ended fork-like curved piece of metal a is guided with its upper narrowed part Zin a guide-piece b, fastened on a band of india-rubber or a like material d. A thumb-screw@ in the'guide-piece `l b serves to hold the fork in the desired position.` The band is fastened by a buckle or a like device around the head of the person to be operated upon in such a way that the guidevpiece rests upon the' forehead. The fork is h. These two ends are pressed together by the .fingers of the operator and are thus inserted into the nostril, when by letting go the vfingers they will press outwardly the outer wall of the nostril. Asthe coil-spring is resting upon the upper lip, it does not in any way interfere with-the work of the operator.

Having now fully described and ascertained the nature of my said invention and in what manner the same is to be used, I declare that what I claim is- In combination the curved fork a, having ftwo hook-shaped ends t' and a narrowed upper part Z, the guide-piece b, with the thumbas set forth.

KARL HOHMANN.
