SURGICAL INS'IBUHENT.
Application fled January- 1 a, 1925. Serial imam.
This invention relatesto surgical instruinsulated from each other and the base for ments, and more particularly to diagnostic lamps for dental and general surgical use, one object of the invention being to provide a practical and convenient instrument of this a type having a readily detachably sanitary jacket or casing so thata plurality of such casings may be provided for use interchangeably with each lam for equipping it selectively with various light projecting arrangements and also for conveniently affording a' supply of sterilized casings. Another object is to rovide such an instrument in which both t e sanitary casing and lamp are readquired from time to time in use. A further object is to provide such an instrument hav-. ing a simple, practical and economical form of construction for the base and the associated parts of the latter supporting the sanitary casing and lamp and supplying the latter with electrical power. To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.
, In the drawings Figure 1 is an external view of a lamp embod ing the present invention;
Figure 2 is a similar view but showing a different sanitary casing;
Figure 3 is a side view of the instrument 7 shown in Figure 2 with the sanitary casing insection, and
Fi re 4 is a view similar to Figure 3 with additlonal parts in sections.
Similar reference numerals throughout the several views indicate the same parts.
The present invention comprises, generally speaking, a holder or base on which are mounted elongated, rigid supporting and conducting means for the lamp, with a sanitary casing enclosing the latter and detach ably secured to the base. In the present instance the base is in the general form of an irregular metal sleeve 5 having a cylindrical portion 6 rovided with a lug or spur 7 for securin t e instrument in a suitable holder or han le as well understood in the art. At 8 is a knurled portion by which thebase may be securely gripped.
The lamp su port-ing and circuit means are carried in t e bore of the base, compris- 56 ing a pair of elongated, rigid metal elements with a bayonet slot 14 for cooperation with a supporting the lamp and sup lying the same with current. One of these ements is preferably an elongated sleeve 9, one end of which is slightly reduced in size as at 10 to a diameter less than that of the bore of the base 5 through which it extends as shown. A sleeve 11 of any-suitable insulating material is interposed between the base and the sleeve 9, the end of which projects from the base. as at 12 to form a contact for connecting the instrument in circuit. The opposite end of sleeve 9 serves as a socket for receiving and holding the lamp 13, the sleeve being formed pin 15 on the lamp so that the latter is readily detachable, as well understood in the art.
The other conducting or circuit element for the lamp is preferably in the shape of a metal post 16 mounted in a sleeve 17 of any suitable insulating material fixed within the sleeve 9 as shown and projecting beyond the latter as at 18 to form a second contact for connecting the lamp in circuit. The other end of post 16 is equipped with a conducting spring 19 arranged to contact resiliently with the other or end terminal of the lamp. It will thus be seen that the latter is supported by simple and rigid means comprising the sleeve 9 which with the post 16 and their spacing and insulatin sleeves are forced into or otherwise fixed in t e bore of the base 5 and themselves serve as the conducting means for the lamp circuit and alsothe contacts by which the latter is connected with the external circuit means.
The lamp and its supporting and circuit means areenclosed in a uid tight, sanitary casing 20 preferably constructed of opaque glass cemented at one end in one end of a 05 thimble 21, the other end' of which is internally threaded for detachable engagement with the externally threaded end 22 of the base 5. The end of thimble 21 is adapted to be turned home against a shoulder 23 on the base and is also formed with a knurled portion 24 by which it and the sanitary casing may be gripped. The sanitary casing is spaced from the lamp and its supporting means as shown to eliminate heating and is 106 provided adjacent the lamp with a transparent glass portion 25, preferably of the lenticular formation shown, for rojecting the light from the lamp on to the o ject to be examined. This lens may be incorporated with 110 the tubular casing 20 in any suitable man ner as by cementing or fuel]; the periphery of the lens to the periphery 0 an opening in the casing and preferably in such a manner thatthe casing and lens surfaces are substantially continuations of each other to aiiord a smooth casing surface. As hereafter described the lens portion may be arranged in different relations on the casing to suit various conditions of use and it is apparent thatarranged at one side of the end of the casing for. projectingl the light laterally. Casings of variousot er forms may be supplied to afford a set adapted to meet substantially any requirements in use, all of such casings being conveniently detachable from the base for use interchangeably. Such casings are well adapted for sterilizing treatment. when detached and it is convenient also to provide two or more of each form of casing for the purpose of maintaining a supply of one or more sterilized casings on hand.
It is apparent from the above description that the invention provides an exceedingly convenient and practical lamp in which the lam bulb and easing may be readily replaced by the user when worn out or broken, thus obmating the purchase of an entire new instrument when such arts become defective. The ready detachabi ity of the casing contributes convenience in sterilizing the same and provides for the use of a supply of sterilized casings as well as of different casings especially ada ted to different circumstances in use. The ase and its lamp supporting and circuit parts are rug ed and durable and economically few in num er and simple from a manufacturing standpoint.
