EUGENE CARPENTER, 01? OAK BLUFFS, MASSACHUSETTS.
Specification of Letters Patent.
Patented Sept. 2, 1919.
Application filed November 21, 1917. Serial No. 203,086.
To all whom it may concern:
Be it known that I, EUGENE CARPENTER, a citizen of the United States, residing at Oak Bluffs, in the county of Dukes, State of Massachusetts, having invented a certain new and useful Improvement in Surgical Instruments, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to tools or instruments for applying cleansing or disinfecting solutions, or medications, tosores or diseased tissues located in subcutaneous portions of the body, or in inaccessible or hidden positions therein.
More especially my invention consists in an instrument of the character described by which such solutions or medications may be alternatelyintroduced into the place under treatment, and then withdrawn therefrom; with the capacity of repeating fresh applications and withdrawals as many times as desired; all these results being efl'ected without removal or shifting in position of the instrument, but merely by the manipulation of suitable means with which my instrument is provided, and preferably operable by the pressure of a finger or thumb.
My invention finds one of its principal applications in dental work for the treatment of disease in. the alveolar process or of ulcers or sores located near the base of the'tooth or in the jaw. I have in conse quence, in this application, shown and de-- scribed my invention as embodied in an instrument designed for this especial use, without, however, thereby intending to limit its use in such manner.
invention is shown in one of its preferred forms in the drawings which form apart of this application and is described in this specification by reference to such accompanying drawings.
In said drawings,
Figure 1 shows, in medial longitudinal section a-dental instrument embodying my invention.
Fig. 2 shows a side elevation of said instrument, partly in section.
Fig. 3 is a view in section on an enlarged scale showing the introducing nozzle of an instrument designed for dental work, in operativ'e'position with respect to atooth under treatment.
Fig. 4 shows an introducing nozzle more especially designed for the treatment of boils, hypodermic sores, or the like; the same being shown on a somewhat larger scale than the nozzle in Fig. 1.
Referring to the drawings,--
1 represents the body of the tool or instrument, preferably composed of pulp or other suitable material molded into shape while in a plastic condition, and thereafter allowed to set or harden. Traversing the body of the instrument are channels preferably embodied in pipes bent to shape and positioned in the proper location in the mold in which the body is shaped, so as to become permanently incorporated in the plastic mass of which the body is molded. Said channels or pipes are disposed as follows: Pipe 2 leads from an external position 2, forming 'an extension adapted to receive a flexible hose pipe 3 and emerges from the threaded boss 4 which is located in the central part of the body. Pipe 5 also emerging from the same boss 4: leads to a port, 5, opening through the wall of a valve chamber, which contains the valve 6 preferably axially located in the forward part of the body. Pipe 7 leads from port 7 also opening into said valve chamber, to an external extension 7 located preferably at the rear of the body and adapted to receive the hose 8.
Said Valve 6 is preferably arranged to slide longitudinally within, and in leakage proof relation with respect to the walls of the valve chamber, and is provided with appropriate means, hereinafter to be described in detail, by which longitudinal position of said valve in said valve chamber may.
be controlled. By preference the forward end of said valve is provided with a projecting portion 6 of reduced diameter, adapted to slide in close fitting relation within alongitud'inal hole 9 leading to the end of the tool where an introducing nozzle 10 is carried at the end of the tool by a ball and socket joint or by other means calculated to permit angular adjustment in position with respect to the body.
A passage 11 extends throughout the length of the introducing nozzle, and in forming the ball and socket joint by which said nozzle is attached to the tool end, suitable provision is -made so thatthe saidnoz- V wardly throughfacutaway portion'of the tool-body and engages within a slot 15 example 6 zle passage is in communication with said longitudinal hole 9 during its entire range of angular adjustment. V
The valve 6 is provided with an interior passage 6 traversing the valve extension 6 and extending rearwardly through the body of the valve for a portion of its length; then branching outwardly to outlets 6 and 6 located on the circumference of the valve. The location of the valve in the valve seat, and of the said branch outlets in the valve are so arranged in position with respect to the ports 5 and 7*, that at the forward limit. of movement of the'valve 6 one of said outlets, asfor example 6, is in registration with the port 5 ,]at' the rearward I limit of movement the other outlet, as for a is in registration with the port 7*. V
. The preferred mechanism for controlling the operation of the valve 6 is as follows:
A T -sha'pe'dlever 12 is pivotallyicarried onthe pin 13 mounted in ears 14: formed on forming a [part ofsaid lever, extends'downformed infthe rear end of the valve :6. The
extreme end of said arm 12? bears against a spring 16; which spring preferably has depressions formed therein. When said lever end 12 rests in the central depression on the spring the relation of operating parts 7' is such that the valve is positioned in the neutral or inoperative position. When said lever end is positioned in the depression in front of said central depression the valve is so located thereby as to bring the valve 6 outlet 6 in registration :withthe port 5' 4O H V V a V -establ1shmg; IGOIHIIlllDlCfltlOIl between pipe -5' and the passage of the introducing nozzle.
When the lever end is positioned in the depression at the rear ofthesaid central'depression the'said' valve is positioned so'a's f;to br ng the valve outlet 6? in registration 'with. the port 17?, establishing communication between the pipe? and the passage of 5o 7. the exterlorjof the boss" 41preferablyby a the introducing nozzle. 1'- 4 g A container 17 is provided which engages -pipe thread connection, so asfto he-mounted vided and is connected with the pipe 2 by 7 upon said boss 4 ma leakage proofrelation.
"When so mounted'theends'ofjthev pipes 2 and: 5' are located in the interior of the container. The container-is preferably pro- A source of pressure (not shown in the l means of "a preferably flexible tube 3 attached to the'glextension 2 p In similar man- -'ner a vacuu-mproduc ng'source (not shown 1n'the.draw1ngs,)'1s connected by means of drawings but of any approvedtype) is pro- 7 a tube 8 engaging the extension end 7 ofx the pipe 7.
The manner of using my device is deof thealveolar'process, 19Vl0cated at the base thereofwithin the jaw;-a portion of which jaw isindicated at 20. A suitable channel 21 having been previously prepared in said tooth, leading to the diseased region, 7 the introducing nozzle 10 of the tool is in,
serted as far as possible within such. chan: nel a leakage proof connection of the introducing nozzle within saidchanneliloelng esta'lolished by the action of a packing washer 22 (which may be adjustableso that the end V of the introducing nozzle 7 may extend 3 through the packing washer or be flush with it as desired) provided at the end of the introducing nozzle.
When the tool is in the desiredposition Q the rearward end of, the controlling lever'1'2 V is depressed, throwing the valve 6 into the forward position, wherein it establishes communication with the pipe 5 and theintroducring nozzle. Thereupon, the tool being held so that the open end 5 of the pipe5 will extend downwardly into and'be submersed in sure transmitted from the source of pressure through the hose 3' and pipe 2' to the interlor "of the container 17 will force a portion of the contents of the container into'the region of the tooth under treatment; a suflicient desaid contents as is shown in Fig. 1, the pres gree Of pressure being employed to insure that the solution or medication penetrates to the place under treatment. Y i 7 ""After the expiration of the period rej quiredto allow the solution or ,medication to act, the'forward end of the controlling lever V is depressed, throwing the valve'6 into; the
position wherein it establishes communicae tion between the pipe 7 and the passage of the introducing nozzle: In su'ohvalve position the .solutionjust previously introduced will bejsuckedoutand removed from the place under treatment? Thereafter by suite 7 able manipulation of the valve controlling I lever a fresh supplyoffsolution or medication may be forced to the part :under treatment and later removed, and thisprocess of introduction and removal may be continued without disturbing the position of theinso long as a supplyiremains in the container strument. It should benotedthat the necessary manipulations can readily be effected by ment is heldin operating-position f;W here a subcutaneous'sore, as for example" a boil or ulcer pocket, is to be treated, I employ an introducing nozzle in the general-I30 form of a stiletto point terminating in a perforated end having the usual characteristics of a hypodermic needle. Said stiletto point is of such dimensions as to permit the needle end of the same to be introduced into the interior of the boil or ulcer pocket by penetrating the flesh tissues by which the same is inclosed; my idea being to obtain access through the ulcer wall to the said interior by the stretching or pressing away of the nerves and other fibers embodied in the tissues of the said wall adjacent the point of penetration as distinct from the cutting or lancing of the same, which would sever many small nerves not liable to reunite again when the cut healed. When the stiletto point has been so introduced, the boil or ulcer pocket may be interiorly flushed with cleansing solutions or treated with medications by alternate applications and subsequent withdrawals thereof, effected by the manipulating of the valve lever in the same general manner as has been hereinbefore described.
