GEORGE E. PEDDLE, OF PERRY, NEW YORK.

SURGEONS SCISSORS.

Application filed January 25, 1910.

Specification of Letters Patent.

Patented Oct. 18, 1.910.

Serial No. 540,100.

To all whom it may concern:

Be it known that I, GEORGE H. PEDDLE, citizen of the United States, residing at Perry, in the county of Wyoming and State of New York, have invented certain new and useful Improvements in Surgeons Scissors, of which the following is a specification.

This invention relates to surgical instruments and more particularly to that class of instruments known as surgeons scissors.

The object of the invention is to provide an instrument of simple and durable construction, especially designed for cutting or removing turbinated bodies from the nasal cavity.

A further object is to provide a pair of scissors, one cutting blade of which is extended longitudinally beyond the other and provided with a curved or rounded terminal which serves to direct or guide the instrument when inserted in the nasal cavity, and

at the same time prevent cutting or lacerating the olfactory membrane and soft tissues of the nose.

A further object is to form the cutting edge of one blade with teeth or serrations to prevent slipping of the blades during the cutting operation.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency, as well as to reduce the cost of manufacture.

Further objects and advantages will appear in the following description, itbeing understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge ofthe details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a perspective view of a pair of scissors constructed in accordance with my invention; Fig. 2 is a side elevation looking at the opposite side of the scissors; Fig. 3 is a perspective view of a portion of the scissors showing the cutting blades thereof in closed position; Fig. 4 is a detail perspective view illustrating a modified form of the invention.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The surgeons scissors forming the subject matter of the present invention comprises cutting blades 5 and 6 pivotally connected at 7 and each having one end thereof bent laterally at S and provided with a terminal finger loop 9. The cutting edge of the lower blade 6 is toothed and serrated, at 10 to prevent slipping during the cutting operation, the free end of the upper blade 5 being projected longitudinally beyond the adjacent end of the lower blade 6 to form a relatively thin flexible extension or guide 11, the terminal of which is slightly thickened and curved or rounded, as indicated at 12. By extending the free end of the blade 5 longitudinallybeyond the blade 6, the extended or projected portion 11 of the blade 5 serves to direct or guide the instrument when introduced within the nasal cavity, while the curved or rounded terminal 12 serves to prevent cutting or lacerating the soft tissues or membrane of the nasal cavity when positioning the instrument on or beneath the turbinate bones of the nose. It will here be noted that the extension or guide 11 is curved laterally so that the instrument may readily follow the contour of the nasal passages, while the opposite edges of said extension are rounded, thus to present a smooth unobstructed surface.

The serrations on the cutting edge of the blade 6 may be of the construction shown in Fig. 1 of the drawings or in the form of scallops, as indicated at 14 in Fig. 4 of the drawings. It will of course be understood thatthe curvature of the blades 5 and 6 may be varied so as to allow the instrument to fit beneath any of the turbinated bodies of the nasal cavity, the angle of the blades corresponding with the anatomy of the turbinate bones or bodies. Attention is here called to the fact that the cutting edge of the blade 5 terminates at the end of the serrated cutting edge of the blade 6, the walls of the extension or guide 11 being devoid of surface projections throughout the entire length of said guide.

Having thus described the invention, what is claimed as new is:

1. A pair of scissors including pivotally connected blades, one of which is provided 1 cutting edge of the mating blade to form an extension constituting a guide, the Walls of which are curved and the terminal thereof blunt and rounded.

In testimony whereof I afl iX my signature in presence of two Witnesses.

tioned blade and curved laterally to form an extension constituting a guide, upper and lower longitudinal edges of the guide being curved and the terminal thereof blunt and rounded.

2. A pair of scissors including pivotally connected blades, one of Which is provided with a serrated cutting edge and the other With a straight cutting edge, the end of the blade having the straight cutting edge being projected longitudinally beyond the serrated l
