Application February 12, 1935, Serial No. 6,135

3 Claims.

This invention relates to improvements in surgical equipment and particularly to improvements in illuminating attachments for cautery instruments.

5 An object of the invention is to provide a new, simple and eflicient illuminating attachment for cautery instruments.

Another object of the invention is to provide an attachment of the type described of such character that it can be secured to the cautery instrument in different desired positions.

A further object of the invention is to provide an illuminating attachment for cautery instruments of such character that the attachment is completely insulated from other energized parts of the instrument.

A still further object of the invention is to provide an illuminating attachment for cautery instruments of such character that separate m sources of energy can be supplied for the tip of the instrument and for the attachment.

In carrying out the objects of the invention and in the preferred form, an attachment is provided for cautery instruments utilizing tips so formed as to have separated contact members. The attachment carries a source of light rays suitably encased, and the case itself is so shaped as to fit either directly between the spaced contact prongs of the cautery tip or between the socket members in which these contact prongs can be secured. The casing or shield of the attachment is preferably made of some good insulating material, such as flexible rubber, whereby the shield can be positioned either between the prongs of the cautery tip or between the sockets of the cautery handle holding the con tact prongs. Since this shell is of insulating material it becomes necessary toprovide means whereby the source of light rays carried thereby can be energized from a source of energy separate from that used to energize the cautery tip. Accordingly, the socket in which the source of light rays is secured can be supplied with electric conductors which can be connected to a suitable source of energy. Such an arrangement is preferable since it is desirable that a source of light rays be controlled independently of the control of the energization of the cautery tip.

Other features. objects and advantages of the invention will become apparent by reference to the following detailed description read in the light of the accompanying drawing, wherein Fig. 1 is a sideelevation of a cautery instrument having an illuminating attachment secured thereto.

Fig. 2 is a plan view of the sockets for receiving the contact prongs of a cautery tip.

Fig. 3 is a fragmentary view of a cautery tip. 6

Fig. 4 is a perspective view of the casing or shield of the illuminating attachment.

Fig. 5 is a plan view of the socket for the source of light rays, which socket is adapted to be mounted within the casing or shield. 1

Fig. 6 is a side elevation of'a modified form of cautery handle and of a modified arrangement of conductors, both for the cautery tip and for the illuminating attachment.

Fig. 7 is a plan view, partially in section, of the arrangement shown in Fig. 6.

Referring now to the drawing and particularly to Figs. 1 to 5, inclusive, Ill indicates a cautery handle provided with sockets H and i2 for receiving the contact prongs I4 and i5, respectively, of a cautery tip indicated generally by the reference character iii. A handle of the type shown in Fig. 1 has been described fully in my Patent No. 1,988,293, issued January 15, 1935. As set forth in this patent, the sockets II and I! are insulated from each vother, current being supplied to the socket Ii directly by a suitable conductor, while current is supplied to the socket l2 from anotherconductor through a spring contact 20 which can be forced into engagement with a disk-like contact member 2! by means of a trigger 22. A thumb nut 24 is utilized for tightening the sockets H and i2 suinciently to securely retain the contact prongs l4 andl5 therein. As shown in the drawing, the sockets H and I 2 are of such length as to receive the entire lengths of the contact prongs it and I5 which are held in separated position by means of an insulating spacer 25, but it will be obvious that these sockets can be shortened materially, the only requirement being that they be of such length as to securely hold parts of the contact prongs.

Since it is usually desirable to illuminate the region of the body which is being cauterized, provision is made for such illumination by the attachment of the present invention. This attachment is made up of a tubular casing or sleeve 30, preferably of some good insulating material, such as soft rubber. The sleeve 30 is provided at one end with an extension 3| in the opposite sides of which are recesses 32. This same end of the sleeve .80 is tapered off as at 34 for a purpose to be described later. Insertable within the sleeve 30 is a tubular socket member as 35 in the end 01' which is secured a light bulb 35. This light bulb 36 can be of any desired form, but in order that the rays emanating from the filament therein may be concentrated at the desired point, the bulb is provided with a condensing lens 31 as shown. The usual electric conductors 38 are attached to the socket in such manner as to permit one of them to be secured to the shell of the contact itself and the other to be secured to a central contact member insulated from the shell. Inasmuch as this particular arrangement forms no part of the present invention and has been shown in detail in my Patent No. 1,990,972, issued February 12, 1935, it is not described or illustrated herein in detail. The socket 35 is of such size as to fit snugly within the sleeve 30 so that the socket can be adjusted longitudinally of the sleeve until the light bulb attains a position for the most efficient radiation of light rays, in which position the socket is held frictionally.

The use and operation of the arrangement just described is substantially as follows: Inasmuch as the sockets I l and I2 are of such length as to receive practically the entire expanse of contact prongs I4 and IS, the sleeve 30 with the socket 35 and light bulb 36 properly positioned therein, is secured to the socket by seating the sockets in the two recesses 32, either with the sleeve positioned beneath the sockets as shown in heavy lines in Fig. l, or with the sleeve positioned above the sockets as shown in dotted lines in Fig. 1. With the attachment in place, a suitable cautery tip may be introduced into the sockets and locked in place. The sleeve 30 is inclined slightly so that the rays from the source of light 38 are projected toward the remote end of the cautery tip to properly illuminate the portion of the body being treated. Should on the other hand the sockets b shorter than shown in the drawing. or should the cautery tip be secured to the handle in any other fashion, it will be evident that the attachment can be shaped and sized to permit the recesses 32 to receive the contact prongs l4 and i5 of the tip directly. Either arrangement will operate efficiently, since the attachment of necessity moves with the cautery tip in its pivotal movement relative to the handle.

In Figs. 6 and '7 a slight modification of the invention is shown. In this modification the spring contact 20 is eliminated. and in lieu thereof. the trigger 22' is provided with a contact member 50 movable to good electrical engagement with the disk contact 2!. This arrangement is made possible by having one of the conductors 54 connected in such fashion as to lead to a socket H (in Fig. 2) while the other conductor 55 is connected to the trigger 22 in some suitable fashion, for example, a connection with the shaft 56 of the trigger arrangement will sufiice.

The modification shown also incorporates another slight change in construction in that a single cable 50 is utilized entering the hollow handle Hi. This cable 60 is made up of two cords 62 and 64, the cord 62 containing the conductors 54 and 55, while the cord 54 contains the conductors 65 utilized for energizing the source of light rays 36'. The cable 65 is so fashioned that an expanse of cord 54 beyond the end of the cord 62 is provided. This expanse passes through an opening 10 in the hollow handle and is formed into a loop H of such size as to permit the sleeve 30' to be attached to the sockets, either in the position shown in heavy lines in Fig. 6, or in the position shown in dotted lines in Fig. 1.

It will be apparent, of course, that the cable arrangement of Figs. 6 and 7 can be used in connection with the handle arrangement shown in Fig. 1, and at the same time the separate cord arrangement shown in Fig. 1 can be used in connection with the contact arrangement of the handle of Figs. 6 and 7.

The tapered portion 34, before referred to, is provided to permit ready introduction of the cord connected to the socket 35 into the sleeve.

It will be apparent from the foregoing that the present invention in any form shown provides a new. simple and efficient arrangement for illuminating the area of a body so that this area can be cauterized. The provision of separate energization circuits for the illuminating device and for the cautery tip permits control of either one of these energized devices independently of the other. Since the sleeve is of insulating material, it may be secured readily either directly to contact prongs of a cautery tip or to the socket receiving these prongs without interfering with the energization of the tip. The arrangement shown in l, naturally, has the advantage that the illuminating attachment can be entirely removed from the cautery instrument should the use thereof become unnecessary. Under certain circumstances, however, the arrangement of electric cable shown in Figs. 6 and '7 may be desirable.

While the present invention has been described with particular reference to cautery instruments it is to be understood that the invention is not to be so limited, s nce the illuminating attachment can be used equally well with other types of electrically energized surgical instruments so long as the instruments employ electrodes or other devices having a work portion. The attachment is designed to illuminate the portion of the body to be effected by the work portion of the electrically energized surgical instrument whether this instrument utilizes heat or any other results which may be obtained from the electrical energization. Accordingly, any limitations imposed upon the invention are to be such as are set forth in the following claims.

I claim:
