FINN J, BRONNER, 0F BRADFORD, PENNSYLVANIA.

DENTAL INSTRUMENT.

Application filed June 4,

To all ywlw/n t may concern.'

Bc it known that I, FINN J. BizoNNiin, a subject of the King of Norway, and iesident oi'' Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Dental Instruments, of which the -following is a specification. j

This invention relates to dentistry, and particularly to a hollow drill adapted for use in penetrating bone structures such as v the jaws or mastoid processes of a patient in order to provide drainage (in abscesses) or to inject anaesthetics or other fluids into the nerve canals or. interior structure of the bones where such internal treatment is desired. y

It is an object of this invention to produce a device which can be operated by a dental engine as an auxiliary to the hand pieces of such dental engine; and the said invention comprises what might be termed a chuck to which a hollow drill is connected, the said device being associated with novel means for preventing fouling of the passage in the hollow drill'through which suction oi' drainage can be established or the medicated fluid is to be forced after the drill has cut its way into that part of the anatoniy to be treated, drained or anaesthetized.

It is a further object of this invention to produce a hollow drill or needle such as is employed for hypodeimic injections and the like, associated with novel means for pre-` venting cuttings from entering the orifice in the drill or needle; the said device being intended to be employed in association withv a syringe or liquid forcing agent whereby the medicated liquid will be injected to the point where local. treatmentis desired.

1With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination o'l parts t-o bc hereinafter more `fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this invention wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation of a device embodying the invention illus- 1923.

trated as associated with a hand piece ofy a dental engine and a liquid forcing device;v

Figure 2 illustrates la sectionall view of the said device;

Figure 3 illustrates a sectional view showing the partsV in different positions of adjustment; l

Figure 4 illustrates a sectional view Lon a line corresponding with the line 4-4 of Fig. 3;

Figure 5 illustrates a View in `elevation partly in section, showing' a device applied as an attachment for a hypodermic appaiatus; 'i l. Figure 6 illustrates a view in elevation of said device; and f Figure 7 illustrates a view in. elevation of the handle and cleaner embodying a slightly modified construction. i In these drawings, 10 denotes an' ordinary hand piece of a dental`engine,'and l1l a liquid forcing device, such as a syringe, that are conventionally showna'nd need not be described in detail; The attachment comprises a shank 12 that is applied ytothe hand piece, although any other `suitable means may be provided 'for its rotation; and the said shankextends into a cylinder 13 through the aperture 14 of a removable head 15, which hea-d is preferably threadedin place. The shank has an annular flange 16 seated at the end vof the cylinder, and a packing 17 is interposed between the flange and the inner wall of the head to prevent leakage when the device is in operation.

The shank` extends through an opposite head 18 on the cylinder, Vand the'said shank tained in the end of the vsaid shank, the said plug constituting an anchorage for the cleaning pin 2 0 that `is used for preventingr the accun'uilation of Yfoi'eigi'i substances in the hollow drill, as will presently appear. The plug has a plurality ot' longitudinally disposed grooves 21 in its outer surface that forni clearances or channels for the passage of the medicated fluid which is to be injected through the hollow drill into the cavity to be treated. That portion of the shank within the cylinder has ak longitudinally disposed slot 23 in which a pin 24 is slidable, the said pin being anchored to the head 25 of a tube 26 that is slidable through 90 has an apertured plug 19 frictionallyfrethe saidconnection 29 may be employed. for

Any suitable connection may be a means. for effieeting`A` connnuthe .source of medicated fluid with the cylinder, and the inventoi'does not wish to be limited with respect kto* ,these detailsbuuias illustrateda when the-.syringe is applied .to .the connectionand fluid is. forced into the cylinder, it Will result inmoving yas the.y Vparts .of the positions in` which 4they are shown in Eig. ,3 of the drawing.

The cleaning needle 38 of the form p shown inv Fig. 7 is of the same general type astliat lieretofoI-'edescribed, and the only difference between the device of Fig. 7 and that 'of Fig. 5 is that .provision is madefnA a more secure `connection between `the s hanlcof theliandle and the socketjofthe head.
