## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application No. 61/466,224, filed on Mar. 22, 2011. The entire disclosure of the above application is incorporated herein by reference.


FIELD OF THE INVENTION
This invention relates to adjustable dental tools and more particularly, to a novel apparatus where the head of the tool includes an accordion section which allows the tool to be bent and twisted for maximum adjustability.
BACKGROUND OF THE INVENTION
Often, a dentist's view and working environment in a patient's mouth is obstructed because of lack of adjustability of his dental mirror and/or instrument. A problem with current designs is that the adjustability, if any, is restricted to the location of the hinges or the orientation of the mirror and instrument.
SUMMARY OF THE INVENTION
The present invention contemplates an adjustable dental tool in which the working portion of the tool can be manipulated relative to the tool handle to position the head in a desirable configuration to carry out a task or to provide a better viewing angle within a patient's mouth. In one form, the present disclosure provides a dental tool that may include a head and a handle. The head may include a working portion and a neck. The neck may include a first end and a second end, and the working portion may extend from the first end. The handle may include a clamp and a socket. The socket may be configured to receive the second end of the neck. The second end may pivot within the socket to move the working portion and the neck relative to the handle. The clamp may be adapted to selectively fix the second end relative to the handle.
In another form, the present disclosure provides a dental tool that may include a working portion and a neck. The neck may include a proximal end and a distal end. The working portion is coupled to the distal end of the neck. A sleeve couples to the distal end of the neck and is movable between a first position allowing the working portion to rotate relative to the neck and a second position restricting rotation of the working portion relative to the neck.
In another form, the present disclosure provides a dental tool that may include a working portion and a neck. The neck may include a proximal end, a distal end and a first longitudinal axis extending between the proximal and distal ends. The working portion may be coupled to the distal end of the neck. A handle may include a first end, a second end and a second longitudinal axis extending between the first and second ends. The first end may be coupled to the proximal end of the neck, and the neck may be movable relative to the handle between a first position in which the first and second longitudinal axes are substantially collinear and a second position in which the first longitudinal axis is angled relative to the second longitudinal axis.
The design offers the advantages of allowing different dental heads to be used with the same handle which will allow the tool to be sold in kits, thereby reducing the cost of the tool since only a single handle is needed for a multitude of dental heads. Further, the handle can include a single coupling portion on its proximal end for attachment of a single dental head, or it can include a plurality of coupling portions on both ends for attachment of a plurality of dental heads.
The design offers an additional advantage of maximum adjustability of the dental head. The adjustable portion of the neck of the dental head provides for pivoting movement of the dental head relative to the proximal end of the dental head and radial twisting movement of the dental head relative to the longitudinal axis of the neck. The adjustable dental tool provides the dentist with the capability to adjust the dental head to a multitude of positions for optimal viewing or operation within a patient's mouth.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
FIGS. 1-15 illustrate various views of an adjustable dental tool 10 including a handle 12 and a head 14 that can be placed in a patient's mouth. Referring to FIGS. 1-5, the head 14 includes a neck 16 having a distal end 26 and a proximal end 27. The neck further includes a ball 18 located on the proximal end 27 of the neck 16 and a working portion 20 on the distal end 26 of the neck 16, which is in the form of a mirror 22 according to this embodiment. As will be discussed in greater detail below, the ball 18 can be pivoted to affix the head 14 and ultimately the working portion 20, e.g. the mirror 22, in a desired position. The head 14 additionally includes a male coupling portion 24 or female coupling portion on the distal end 26 of the neck, which is a male threaded portion 24 in this embodiment. The proximal end 28 of the working portion 20 includes a complementary female coupling portion 30 or male coupling portion, which is a female threaded portion 30 in this embodiment that is in engagement with the coupling portion 24 of the neck 16.
Referring specifically to FIG. 2, the handle 12 includes a clamp 32 and a socket 34 coupled to a distal end 36 of the handle 12 for attaching the head 14 to the handle 12 and adjusting the neck 16 to a desired angle relative to the longitudinal axis of the handle 12. The clamp 32 includes a male coupling portion 38, 40 or female coupling portion on both its proximal 42 and distal 44 ends, which is a male threaded portion 38, 40 in this embodiment. The distal end 36 of the handle 12 and a proximal end 42 of the socket 34 both include complementary female coupling portions 46, 48 or male coupling portions, which are female threaded portions 46, 48 in this embodiment that are in engagement with the coupling portions 38, 40 of the clamp 32.
The socket 34 further includes a receptacle 50 for receiving the ball 18 on the head 14 of the adjustable dental tool 10. As discussed in greater detail below, the ball 18 fits within the receptacle 50 so that the neck 16 exits through a slot 52 located in a distal end 54 of the socket 34. The slot 52 allows the neck 16 to pivot in a range of 0° to 90° from the longitudinal axis of the handle 12, in conjunction with the ball 18 as the ball 18 is rotated within the receptacle 50, altering the position of the working portion 20 relative to the distal end 54 of the socket 34 (further demonstrated in FIG. 5). Further, the ball 18 may be twisted in a range of 0° to 360° both clockwise and counterclockwise in the radial direction along the longitudinal axis of the handle 12, altering the position of the working portion 20 relative to the axis running the length of the handle 14. The neck 16 may also be rotated and twisted simultaneously. The coupling of the clamp 32 and the socket 34 may be tightened such that the distal end 44 of the clamp 32 contacts the ball 18 and increases a compressive force on the ball 18 from the clamp 32 and the walls of the receptacle 50. The application of the compressive force will cause the ball 18 to remain in its set position thereby temporarily fixing the position of the working portion 20.
As Illustrated in FIGS. 6 and 7, the adjustable dental tool 10 may include a variety of working portions 20.
