Abstract

A gripping handle for a diagnostic instrument, such as an intraoral dental camera, in which the instrument includes an elongate body having an integral camera head and a protective sheath having a transparent window which overlays the camera head. The gripping handle is a unitary hollow section of an elastomeric material which is fitted over a portion of the instrument body and clamps the sheath in a predetermined position to prevent the sheath and the transparent window form being twisted during use. Preferably, the gripping handle and the instrument body can each be made from a biodegradable and recyclable material allowing one time use of each.

Claims

1. A diagnostic instrument assembly comprising:

an elongated instrument body having a distal camera head;

a flexible protective sheath for loosely covering at least a portion of said instrument body including said distal camera head, said sheath including at least one transparent window for allowing viewing access by said camera head; and

a gripping handle made from a single section of an elastomeric material, said gripping handle being releasably attachable to at least a portion of said elongated instrument body for clamping said protective sheath in a predetermined position, so as to prevent said at least one transparent window from being shifted relative to said camera head wherein said gripping handle is a hollow tubular member having an inner diameter which is smaller than the outer dimension of said elongated instrument body such that said gripping handle is expandably form fitted over said sheath and said body.

2. An assembly as recited in claim 1, wherein said instrument body is that of an intraoral dental camera.

3. An assembly as recited in claim 1, wherein said gripping handle is disposable.

4. An intraoral dental camera assembly comprising:

an elongated instrument body section including a distal camera head fixedly attached thereto;

a flexible protective sheath for loosely covering at least a portion of said body section, including said camera head; and

a unitary sleeve member releasably attachable to at least a portion of said body portion for clamping said protective sheath in a predetermined position so as to prevent twisting of said sheath during use, said sleeve member being made from a tubular section of an elastomeric material having an inner dimension which is no larger than an outer diameter of said elongated instrument body to allow form fitting thereto.

5. A camera assembly as recited in claim 4, wherein said gripping handle is disposable.
