BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates generally to a holder and a sheath and more specifically to a dental X-ray sensor holder and a corresponding dental X-ray sensor sheath for removably securing a sensor in said sheath to a backing plate of said holder for X-ray acquisition.

Related Art

A conventional dental X-ray acquisition can be performed by positioning an X-ray source on one side of a patient and transmitting X-rays through a site in the oral cavity to be irradiated, and toward an x-ray detector located in the oral cavity.

U.S. Pat. No. 3,473,026 discloses a device for positioning dental X-ray film within the mouth for producing radiographs. It is hereby incorporated by reference for background purposes.

In a manner similar to the use of x-ray films, holding and positioning devices have been developed for x-ray sensors and phosphor imaging plates.

One way Dental X-rays sensors have been positioned for image acquisition is through the use of adhesives. More specifically adhesives are used to bond a holder to an encapsulated film or sensor as disclosed in U.S. Pat. No. 6,811,312.

U.S. Pat. No. 7,004,627 discloses a barrier and cushioning apparatus for use with sensors as a means to avoid contamination of the sensor while providing reduced discomfort through the use of a cushion cover that may incorporate an integrated adhesive section for securing to a positioning accessory such as a sensor holder.

However these holders can be bulky and accompanying adhesives may be time consuming to apply to holders when multiple radiographs are needed. Moreover, some adhesives may not be suitable to be used in the oral cavity. It is therefore desired to create a holder that is compact, inexpensive, simple and eliminates the use of adhesives to hold X-ray detectors.

Multiple types of X-ray detectors exist. A dental X-ray film for example is positioned relative to the target site in a predetermined and secure manner in order to obtain a useful image.

More recently, traditional X-ray films have been replaced with X-ray sensors. An example of such a sensor is shown in U.S. Pat. No. 6,652,141 which is hereby incorporated by reference for background disclosure of X-ray sensors.

Phosphor imaging plates are also used in the dental industry. The imaging plate is irradiated and the x-ray shot is stored onto the imaging plate to be read later by a scanning machine or the like and the data is transferred to a storage or display device, such as a computer.

These and other type of devices that receive dental X-rays for dental purposes are hereinafter collectively referred to as dental X-ray imaging media, X-ray sensors, sensors, imagers, image media or the like. Any such devices that are sensitive to such X-rays is within the scope of the invention. It is envisioned that in the future, other type of dental imaging media will be developed using similar or perhaps completely different technologies. These all have at least some commonality in that they generally must fit within the oral cavity and they must be securely held in a desired location during the x-ray procedure.

It will be appreciated from the above discussion that the different image media holders while all accomplishing similar purposes, all operate in different manners. However, the need still exists to create a device that is compact, inexpensive, simple and eliminates the use of adhesives to hold X-ray detectors.

BRIEF SUMMARY OF THE INVENTION

Existing limitations associated with the foregoing, as well as other limitations can be overcome by a method and system for removably securing a sensor to a backing plate of a dental X-ray sensor holder using a sheath provided with a strap wherein the strap can receive the backing plate of the holder to physically impinge on it and thereby secure the sensor in position relative to the backing plate. The invention thus comprises a sensor holder with a backing plate, having one or more spring arms and affixed to or formed contiguously with a proximal end of a bite block of the holder, and a sensor sheath adapted to removably secure a sensor in said sheath to the backing plate of said holder for X-ray acquisition.

There has thus been outlined, rather broadly, some of the features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter.

In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction or to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.

An object is to provide a Dental X-ray sensor Holder and Sheath for operably affixing a sensor to a backing plate of said holder. The sheath also acts as a contamination barrier for the sensor.

Another object is to provide a Dental X-ray Sensor Holder and Sheath that eliminates the use of conventional adhesives to affix a sensor to a backing plate of a sensor holder.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the sheath is provided with a strap that is permanently affixed to the sheath to provide a means for attaching the sensor in the sheath to a backing plate of the sensor holder.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the backing plate of the holder, provided with spring arms, which when slid under the strap of the sheath causes the strap to pull on the sheath to tighten it around the sensor.

Another object is to provide a Dental X-ray Sensor Holder and Sheath that for use with different sizes of sensors by having a backing plate with spring arms wherein the arms can extend outwardly to tighten the sheath around the different sized sensors.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the holder is configured for anterior teeth X-ray acquisitions.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the holder is configured for posterior teeth X-ray acquisitions.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the holder is configured for bitewing horizontal X-ray acquisitions.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the holder is configured for bitewing vertical X-ray acquisitions.

Another object is to provide a Dental X-ray Sensor Holder and Sheath wherein the holder is configured for bitewing endodontic X-ray acquisitions.
