BENT vROTATABLE eAsTRoscoPE.
SPECIFICATION forming part of Letters Patent No. 598,787, dated February 8, 1898. Application niet March 20,1897. stanno. 628,491. ciovmoaei.)
To all tzr/tom t may concern.- i
Be it known that I, GEORG EMIL KELLING,
of Dresden, in the Kingdom of Saxony, in the German Empire, have invented a new and useful Bent Rotatable Gastroscope, of which the following is a specification, reference being had therein to the accompanying draW-.
ings.
This invention relates to surgical instruments, and is an improved gastroscope or instrument for visu all y inspecting interior parts of the body, especially the human stomach,
.straight apparatus touches the back membrane of the stomach, which in consequence cannot be inspected. The bent gastroscopes heretofore devised have to be duplicated for the right and left half of the stomach, and not even with these could the lower part nor the back part of the stomach be inspected. This invention avoids these inconveniences and produces an adjustable rotatable gastroscope which allows of the inspection of all parts of the stomach.
In the annexed drawings the new invention is shown.
Figure l represents a section onfr of Fig. 2. Fig. 2 is a longitudinal sect-ion through the greater portion of the apparatus. Fig. 3 is a longitudinal section through the illuminating portion of the apparatus, and Fig. 4t represents transverse sections of Fig. 3.
The outer casing R of the instrument is preferably a metallic tube bent as indicated in the drawings, so as to adapt it to be more readily inserted into the stomach, the upper end of said casing being attached to a headblock B', of insulating material, provided with a bow B, which serves as a handle for the instrument. Vithin the upper straight part of the casing is a smaller tube R2,which projects through a stuffing-box S on the headblock and is provided with a finger-piece u, by which it can be rotated. The inner end of tube R2 is provided with teeth Z, meshing wit-h teeth Z on the upper end of another tube R2,which projects slightly beyond the end of casing R, and on it is secured a hollow rotatable head-section K, which is insulated from tube R2, however, by an interposed insulating-ring j, as shown in Fig. 3. Tube-l R2 is insulated from the casing'by rings jj2 J2, Fig. 2, and tube R2 is insulated therefrom by rings j* j, asi indicated in Fig. 3, these tubes being preferably lacquered between the insulating-rings.
Within tube R2 is a smaller pipe R2,which projects through a stufIing-box S2on the keypiece-u and through a suitable opening in bow B, and has in its outer end an objectglass L', secured by a removable cap D. The inner end of said tube is provided with a tongue Rigwhich extends to the junction of- To magnify the object, lenses L3 and L2 i may be employed, the former being located in a ring H2, secured in tube R2 near prism P, and the latter being secured in a ring H', secured in tube R3, as shown.
Current is supplied to lamp G as follows: On head-block B are opposite set-screws S2 VS3, and the positive wire is connected to S3 and the current conducted through contact-spring F to the casing R', along which it is carried to the head-section K, a conducting ring or strip C3 being located at the j unction of the casing and head-section to facilitate the passage of the current. In the headsection the current is directed through a spring F, arranged in the hollow head K' of the section, to one terminal of the lamp-filament, while the other terminal of the lament IOS is connected to a wire D', which in turn connects With a Wire G2, insulated from the head K and head-section, but contacting With the inner end of tube R'2, through Which the current flows to tube R2, and thence through pipe R3 and bovs B to a variable contact S', and thence through the contact-spring F3 to the binding-post S2. Thus the casing and tubes are made to act as conductors for the electric current.
Air can be admitted through the valve L5 into the casing, the rings j j2j3j4j5, mirror M, and plug jg being suitably notched to allow it to pass on into the hollow head K', whence it enters the stomach through opening O4, or other suitable air-passages may be provided, so as to alloW the air to freely circulate to head K', the stuffing-boxes S S'2 preventing it escaping externally.
From the foregoing description and drawings it Will be understood that after insertion of the instrument the head-section can be rotated so as to direct the rays of light into any part of the stomach, and that the latter can be expanded by compressed air, so as to facilitate the inspection thereof.
Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-
1. In a gastroscope, the combination of the casing, having a rotatable head-section; and an illuminating device in said head-section; With means for rotating said section While inserted in the stomach, for the purpose and substantially as described.
2. In a gastroscope, the combination of the casing, the mirror and lenses therein, and passages for conducting air into the stomach to expand the same When the instrument is inserted in the stomach, substantially as described.
' 3. In a gastroscope, the combination of the casing, a rotatable head-section, reflecting lenses and mirrors, and means for rotating said head-section While inserted in the stomach; and an electric incandescent lamp in said head-section, substantially as described.
6. In a gastroscope, the combination of the casing, the mirrorand lenses therein, and passages for conducting air into the stomach to expand the same when the instrument is inserted in the stomach; With an electric lamp inthe inner end of said gastroscope, substantially as described.
7. In a gastroscope, the combination of the casing, an electric lamp therein electrically connected therewith, with a tube Within the casing electrically insulated therefrom, but electrically connected to the lamp, and electrical connections between said tube and casing and an electrical supply, for the purpose and substantially as described.
8. In a gastroscope, the combination of the outer bentcasin g having a rotatable head-section and an electric lamp in said section; With the rotatable tubes in said casing electrically insulated therefrom, said casing and tubes forming conductors for the electric current, substantially as described.
9. In a gastroscope, the combination of the casing, the rotatable head-section, the lamp in said head-section having one terminal electrically connected to the casing; the insulated rotatable tubes in said casing electrically connected With the other lamp-terminal; the fixed pipe in the inner tube, the mirrors, prisms and lenses, substantially as described, and the insulating-supports for the outer ends of said casing and tubes, and the binding-posts on said supports, all substantially as and for the purpose described.
lO. In a gastroscope, the combination of the outer bent casing, having a rotatable head-section,and an electric lamp in said section; with the rotatable tubes in said casing electrically insulated therefrom, said casing and tubes forming conductors for the electric current; the non-rotatable pipe in the outer tube, the object-glass, lenses, prisms, and reiiectors,ar ranged substantially as described, and means for conducting air through the gastroscope to expand the stomach, all substantially as and for the purpose set forth.
In Witness whereof I have hereunto set my hand in presence of two Witnesses.
GEGRG EMIL KELLING.
