Abstract

External discardable protector for odontological cautery-handles, these being comprised of a body with an elongated grip (2), where an end has mounted moving and settling facilities; housing on the inside the transmission mechanism and the opposite end has a fastening device for tools (3) used in odontological treatments; the aforesaid external discardable protector is comprised of a jacket (10) made up of an elastic membrane in a substantial format of a basically cylindrical and elongated bag, which is 'dressed' on the cautery-handle.

Description

External discardable protector for dental handpieces,
This invention relates to an external discardable protector for odontological cautery-handles, belonging to the field of articles used in odontology and that was developed to protect the patient against incidental contamination by infectious-contagious diseases.
As is known, the cauteryrhandle is one of the most widely used instruments in dental treatments, needing to receive a series of instruments such as burr-drills, support mandrils for polishers, grinders, and the like.
As regards the efficiency and functionality of this instrument, a problem can be attributed to it, which is the fact that during a treatment session, the carrying point of the tool not rarely touches the gums, tongue, teeth, cheeks and lips of the patient, when contamination of the same can then take place by infectious-contagious diseases such as AIDS, Hepatitis B, syphilis (third stage) and the like.
For avoiding this problem, it is necessary to take several precautions with the asepsis of the odontological cautery-handles, which requires time and a bothersome operation and it would be desirable if this could be avoided. With this problem in mind and the intention of overcoming it, the external discardable protector for odontological cauteryhandles of the present patent was developed, which is comprised essentially by an elastic membrane cap with suitable configuration and dimensions for being set around the entire surface of the cautery-handle and being fastened to it by pressure.
This form of build of the external discardable protector solves the above mentioned problem since it impedes direct contact of the point of the odontological cauteryhandle, in that it supports the tool by any surface of the patient's mouth, thus avoiding contamination.
The annexed drawing shows the external discardable protector for odontological cautery-handles of the present patent in which;
Figure 1 shows the protector separately and shows an odontological cauteryhandlc for receiving it;
Figure 2 shows the protector applied to the odontological cautery-handle from a side view and with a section cut for better understanding;
Figure S shows the applied protector from the lower angle of the cautery-handle in which an opening is provided for fastening to the tool; and
figure 4 shows an A-A cut, given in figure 2.
In accordance with what the above listed figures show, the external discardable protector of the present patent is applied to odontological cautery-handles (1) used in dental treatments and which comprises an elongated grip (2), where an end has mounted moving and settling facilities (not illustrated); on the inside the aforesaid body houses the transmission mechanism (not shown), connected to the aforesaid moving facilities and the opposite end of said body has a fastening device (not illustrated) for tools (3) used in odontological treatments such as mandrils supporting polishers, grinders and the like, this device being subject to the transmission mechanism.
Thus, the external discardable protector is comprised of a jacket (10) made up of an elastic membrane in a substantial format of a basically cylindrical and elongated bag, one end of which has a mouth (11) for "dressing" the jacket on the cautery-handle; the body (12) of the jacket has suitable configuration and dimensions for setting it and fastening it by pressure around the entire surface of the cautery-handle, particularly that part which is introduced into the mouth of the patient and the opposite end (13) of the aforesaid jacket is closed and houses the point of the cautery-handle supporting the tool (3) and is provided with a hole (14) large enough for passage of the same.
The jacket (10) can be provided with non-slip ribs
(15) for improving the grip of the operator's hand on the cautery- handle. Such jacket further can be provided with holes in suitable regions for cooling and/or fastening and releasing the drill bit and/or the like. The jacket also can have suitable curvatures for being set to cautery-handles with different shapes such as a straight line or contour made up of a grip stretch arranged at an angle in relation to the supporting point of the tool (as in the illustrations) or the like.
The jacket (10) can be made up of an clastic membrane drawn from natural material such as rubber, or from nontoxic synthetic petroleum derivatives (plastic).
In other build possibilities, the jacket (10) can be drawn from semi-hard plastic or vegetable fibre film (impermeable paper) or cloths or metallic sheets or the like separately or in combination for suitably meeting the following functions: insulation, ease of gripping the set (jacket and cautery-handle), proper adherence of the jacket to the cautery-handle, is not harmful to the mouth cavity, is nontoxic and the like required for the proper performance of the protector.
Irrespective of the material employed in making the protector, it, besides meeting the above mentioned technical functions, must be inexpensive in order to endow the protector with a discardable nature.
Thus, before beginning a treatment session, the protector is "dressed" on the odontological cautery-handle; the tool (3) to be used is mounted in the same by a hole (14) in the protector and the session is carried out normally, being that during the same, no direct contact is made between the cautery-handle and the surface of the mouth cavity, thus avoiding contamination.
At the end of the session, the final tool (30 used is dismounted from the cautery-handle in the normal manner and the protector is "undressed" from the same and thrown away, taking with it any contagious germs.
Logically, the protector with such features is supplied sterilized to the professionals in the area and in separate hermetically sealed wrappers in order to be exposes to the air only at the time of use.
