east. (61. est-tat) This invention relatesto surgical aspi tatols,

"aud ,;moreparticularly to improvements in an aspiratorfordental surgery. 1 t t, jGenerally dental aspirators of the typewith which; the present invention :is concerned; include ,ahandle through which apassage extendsand a hollow tip or tube removablymounted, onwone end of the handle. A set of similar tips, each of which is formed with a differently sized opening, in its operative end, is generally provided with such a handle so that the tips are inter- ,changeable and the .most suitably sized tip can be employed for removal of liquid, semi-solid and solid material, such as blood, saliva, tissue andbone chips from the mouth of the patient.

I-Ieretofore the end of the handle of such an aspirator which received the tip was formedwith a female taper into which the correspondingly tapered male end of the tip was inserted. The connection between handle and tip relied upon was therefore one of axially wedging one part into another, V r

, A dentalaspirator of the type in question is frequently used as a lip or mouth retractor incidental to removing material from the mouth of the patient and this places a mechanical stress on the connection between the tip and handle. In such use of the prior aspirator it was not uncommonfor the tip to loosen and separate from the handle and fall into the mouth of the patient whicnwas undesirable, of course, or onto the floor resulting in contamination of the tip and requiring its resterilization before being used again. Thus inconvenience and annoying delay attended use of this prior aspirator.

Further the tapering of the tip and handle of suchprioraspirator to provide the wedge connection therebetween was such as toproduce a constriction in the passage through which passed the material removed from the patients mouth. Hence when a piece of solid orsemi-solid material large enough to pass through the larger partpf the passage encountered the restriction ittco'uld not passand the passage wouldbecome plugged. This rendered the aspirator inoperative until the passagewas unblocked.

Accordingly, an object of the present invention is to provide an aspirator in which the tip is firmly connected tothe handle and so maintamed during use of the aspirator.

Another object is to provide such an aspirator in which the tip is quickly removable and interchangeable with other tips of similar form. Another object is to provide such an aspirator which will not plug up in use.

The. r en o hethaindlegis shown as b in formed with an axially projecting nipple JS. This nipple I E is adapted to beconnected to a fiegrib lefl tubing not shown) connected to a uuml i tsu t a qum H ew t i mr 'taht-f e ur timer s t nre s in the means for firmly yet duic'hly, re-

niovably mounting the tip H on the handle l0.

by loosening the nut 20.

To this end, the front end of the handle is shown as being formed with an outwardly projecting axial integral neck N5, the outer end of which is externally tapered as indicated at H. Intermediate the tapered end I1 and the main body of the handle H], the neck 16 is externally threaded to provide a male thread It The outer portion of the neck It is radially contractable and for this purpose is slit. As shown, a pair of diametrically opposite slits l9l9 extend from the outer extremity of the neck I6 axially thereof into the threaded portion l8.

A nut is arranged on the neck It. This nut 20 has an opening extending completely therethrough. One end portion of this opening is tapered corresponding to the tapered end I! on the neck [6 as represented by the numeral 2| and the opposite end portion is of enlarged diameter as indicated at 22, the portion of this opening intermediate these tapered and enlarged ends being internally threaded as indicated at 23. The female thread 23 of the nut 20 works on the male thread E8 on the neck 16 so that the tapered end 2| of the nut is engageable with the tapered end I! on the handle [9 when the nut is moved axially of the neck in one direction. The external shape of the nut 26 may be of any desired form and is shown as being bell shaped at its front end merging into a cylindrical rear end, the periphery of this cylindrical rear end portion being knurled, as indicated at 24, to facilitate manually turning the nut.

The passage M which is preferably of uniform diameter throughout extends through the neck l6 of the handle Ill. The outside diameter of the attaching end of the tip H is approximately the same as the diameter of passage l4 so that the tip can be easily inserted and removed from the neck It. To limit the depth to which the attaching end of the tip can be inserted into the neck I6, the tip is shown as being formed with an integral protuberance or collar extending radially outwardly from the exterior of the tip and spaced axially of the tip from the extremity thereof.

In the assembled condition of the parts shown in Fig. 5, the attaching end of the tip IL is arranged in the passage M of the handle it] with the rear shoulder of the collar 25 against the front end face of the nut 20, this nut being arranged on the neck [6. By turning the nut 20 in one direction its surface forming the tapered opening 2| wedges against the tapered end I 'l of the neck and thereby clamps or pinches the neck against the tip II, the slits |9l9 permitting of this radial contraction of the neck. Thus the tip is firmly held on the handle and is not subject to loosening or removal except It is merely necessary to turn the nut a fraction of a turn in the reverse direction to relieve the pressure of the tapered neck end I 1 against the taper 2| so that the tip can be withdrawn from the passage M. The opposed segmental sections of the neck [6 formed by the slits I9l9 are resilient and constantly seek a position in which they are Y concentric with the remainder of the neck. Any

other size of tip having a similar attaching end can be quickly slid into the passage l4 and held in place by tightening the nut 28.

It will be noted that there are no restrictions in the passages I2 and 14 so that any solid or semi-solid material which enters the nozzle end of the tip ll does not encounter a constriction in passing from the passage l2 into the passage 4 I4. Hence the passages l2 and M are not likely to become plugged in use.

The operative end of the nozzle l3 of the tip I l is formed to permit material to enter the passage l2 in the tip when the opening or inlet 26 in the end of the nozzle is closed off. Referring to Figs. '7 and 8, this purpose is accomplished by the provision of a pair of diametrically opposite slits 21, 21 in the operative end of the nozzle [3. Each of these slits 21 is shown as extending axially of the wall of the nozzle and opening to the end face of the nozzle. Thus, if in using the aspirator the nozzle [3 is inserted in a recess in the tissue of the patients mouth and pressed against the tissue so that the opening or inlet 26 is thereby closed, the material in the recess can be still removed by passing through the slits 2! into the passage l2. It will be understood that any number of slits can be provided in the nozzle 13.

From the foregoing it will be seen that the present invention provides an aspirator having a tip and handle in which simple clamping means are provided for firmly but quickly removably mounting the tip on the handle. Further an unrestricted passage through which the material handled by the aspirator fiows is provided by the invention.
