ILLUMINATING ATTACHMENT FOR SURGICAL INSTRUMENTS.
Application filed June 14, 1926. Serial No. 115,724
The present invention relates to illuminating attachments for surgical instruments and an object thereof is to provide a construction which may be readily at"tched to speculums and other surgical instruments where an illumination of the field of operation is desirable. 'Anothcr object of the invention is to so connect the illuminating attachment to the V instrument that, while it may be readily disconnected or detached at will, 1n use, detachment is prevented.
""ld t' onthese and other one s, t 1c 1D en ion c sists of certain parts and combinations of parts, all of which will be hereinafter described the novel features being in the appended claims.
In the drawings: j v Fig. l is a side view of a speculum with the illuminating attachment secured'thereto;
Fig. 2 is an enlarged view of the illuminatattachment partially in'section; and Fig. 3 is a fragmentary view partially in section. r i
The form of material. In this instance, a speculum 1 of known construction is employed, the only change in the construction beingthe provision of an opening2 in the upper pivoted .iember 3 of the speculum 1 adjacent a free edge l on such upper member. The lllllllll? nating device is in the form of a small incane descing lamp Shaving a disbursing lens 6 associated therewith, this lamp being secured in a. socket T from which a tubing 8 extends. At the end of this tubing is formed, one
member of a coupling or connector 9 of known.
construction; The coupling member 9 has a central contact 10 insulated from the outer surface thereof by insulation 11. From the contact 10 a conductor extends through the tubing 8 to a contact 12 in the socket 7 being insulated from the tubing 8 and the socket by insulating material 13. This forms one of the conducting means fromthe contact 10 to the central terminal of the lamp 5. The-casing of the lamp 5 is a conductor andv connects electrically with the socket 7 connects with the tube 8 and the terminal 9.
' The feature of this invention is the manner of supporting the lamp upon the surgical instrument. This supporting means embodies, in this instance, two cooperating elements,
one being rigid with the lamp socket 7 and pointed out the surgical instrument is imwhich in turn shoulders 16 on opposite side s of thehook for a purpose to be described. The other member of the securing means is movable and, in this instance, is in the form of-a plunger 17 having a transverse notch or groove 18 in one end. In this instance, this plunger is mountedto reciprocate in a casing or cylinder 19 which is supported by an arm 20 from the lamp socket 7. In the illustrated construction, the axis of this cylinder is at a slight angle to the axis ofthe lamp socket. This is desirable as the outer portion of the speculum to which this device is attached flares and if the axis or the line of movement otfthe plunger 17 were parallel with the lamp socket, the lamp socket would 7 not throw its rays in the direction of the line may have a st'em 21 secured thereto and extending through the opposite end of the cylinder 19 where it is provided with a knob 22. The stem 21 is guided through a bushing 23. The latter is fitted in the end of the cyl- 7 setscrew' 24. A helical spring 25 surrounds the stem 21 between the bushing 23 and the end; of the plunger 17 and serves normally to project the plunger toward the rigid securing ho'okl la- The bushing 23 has a longi tudinally extending slot 25 in which is adapted toop'erate alateral projection or pin 27 on the stem .21. This pin is also adapted to be withdrawn from the outer end of the slot and the bushing as illustrated in Fig.2 so that it may be turned with the stem 21 and the plunger 17 to engage the end of the bush ing 23 in order to hold the spring 25 under compression to facilitate the ready attachment of the illuminating device to the surgical instrument. The terminal supporting arm 8 with which the usual electrical cord connects is deflected laterally with reference to the socket 7 under. the cylinder 19 and thence upwardly so'that the electrical cord connects with the illuminating device above the cylinder 19 and above the surgical instrument.
In the use'of the invention, the instrument is provided with the opening 2 and the hook 141 is introduced into this opening while the ,plunger is moved'to the position illustrated in Fig. 2 with the spring 25 compressed. The shoulders 16' cooperate. with the inner .inder and is secured against movement by a face of the member 3 of the instrument and with the hook limit the movement of the illuminating device on the instrument. plunger 17 is now released by turning the stem 21 until the projection 27 aligns with the slot 26. As the plunger moves-forwardly under the action of the spring 25, the slotted end 18 engages on opposite sides of the edge 4 of the instrument adjacent the opening 2 and this slotted end with the hook effectively secured the illuminating attachment in place.
hat I claim as my iuvention and desire to secure by Letters Patent is:
1. In combination with a lamp socket, two cooperating securing devices supported by the socket to one side thereof, one of said securing devices being rigid with the socket and the other of said securing devices being in the form of a plunger movable toward and from the first mentioned securing device in a line at an angle tothe longitudinal axis of the socket.
2. In combination with a lampv socket, means for securing said lamp socket to a suitable instrun'ient, comprising a rigid arm extending laterally from the socket and provided with a hooked end, and a plunger supported by the socket and movable toward 7 and from the hooked end oi the arm, said plunger having a groove for the reception of the edge of the instrument.
4. In combination with a lamp socket, means for securing said lamp socket to a suitable instrument, comprising a rigid arm extending laterally from the socket and provided with a hooked end, and a plunger sup ported by the socket and movable toward and from the hooked end of the arm, said plunger being movable on a line at an angle to the longitudinal axis of the lamp socket.
5. In combination with an illuminating device, an arm extending laterally from the device and provided with a hooked end and. a shoulder adjacent said hooked end, a cylinder supported to one side of the device, a plunger movable in said cylinder toward and from the hooked end of the arm and formed. with'argroove, a spring in the cylinder operating to move the plunger toward 7 The said plunger to move the latter "against the action of the spring. 7 'L .6. In combination with an illuminating device, a hook rigidly supported by the device, a cylinder rigidly supported by the device, a plunger movably in the cylinder toward and from the hook and provided with a groove atitsend adjacent hook, a stem secured to said plunge T, a slotted bushsecured in the cylinder and through which the stem operates, a springsurrounding said stem and abutting the plunger and said bushing, a knob secured to the stem, and a projection on thestem arranged to operate in the groove of the bushing and to be with drawn from the groove in the bushing to cooperate with the outer end of the bushing when the plunger is moved to compress the .X'Pl'lllg in order to lock the plunger against movement toward the hook. v
7. In combination with an illun'iinating device, means for securing said device to a suitable instrun'ient embodying two devices, one rigid with the socket and the other in the form of a plunger formed with a groove in its end adjacent the first mentioned securing device, a. spring "for moving said plunger tovi'ard the first mentioned securing device, a stem for moving said plunger to compress the spring, and means carried by the stem 'iermittingthe reciprocating movement of the'plunger and movable with the stem upon the turning of the latter to hold the spring under compression and the plunger away from the firsti'i'ientioned de *ice.
8. In combination with an incandescent lamp socket, a rigid securing device sup ported at one side'oi the socket, a cylinder supported at one side of the socket and extending rearwardly therefrom, a plunger movable in the cylinder toward and from the rigidsccuringdevice, a rigid conductor arm extending rearwardly trom'the socket and outwardly beneath'the cylinder, and a terminal at the free end of the rigid arm.
' 9. In combii'iation with an incandescent lamp socket, of two cooperating securing devices supported by-the socket to one side thereof, one of said devices being rigid'with the socket and extending outwardly there CHRISTIAN C. BOEHM,
