Definitions

  • a dental x-ray sensor holder is provided.
  • the sensor holder has a geometry conducive to receive and secure a digital sensor of the type physically connected to another device such as a computer or the like via a connecting cable.
  • a traditional dental x-ray procedure includes exposing an x-ray film to x-ray energy after it has passed through the target site. The film is developed and an image of the target site is achieved. It has also long been known that in order to obtain a useful image, the dental x- ray film must be positioned relative to the target site in a predetermined and secure manner. Many numbers of x-ray film holders and positioning devices have been developed, including for example, that shown in U.S. Pat. No. 3,473,026 which is hereby incorporated by reference for background purposes. [0004] More recently, many dental professionals have used digital x-ray sensors in place of traditional x-ray films.
  • a traditional problem with sensor holders is that connecting cable affixed to the sensor itself is cumbersome to position such that it does not interfere with the imaging procedure. Patient comfort is always a prime consideration in any dental procedure, and the positioning of the connecting cable is no different.
  • the holder should easily yet securely position and hold not only the sensor but also the connecting cable.
  • a holder for a digital dental x-ray sensor of the type having a connecting cable comprising a bite block affixed to an upstanding frame.
  • the frame is provided with at least one void area at least partially bound by said frame.
  • the frame is further provided with a plurality of latch fingers configured to resiliently receive the sensor in a snap-fit relation so as to removeably secure the sensor to said frame.
  • the connecting cable is positioned through said void area.
  • securing a digital dental x-ray sensor of the type having a connecting cable comprising the steps of providing a holder as above, and inserting the sensor through said void area such that the sensor is positioned on one side of said frame while the connecting cable is positioned through said void area.
  • the inventive method further includes if necessary, turning the sensor such that it is aligned with said latch fingers and snap-fitting the sensor to said frame and into a snap-fit receiving relation with said latch fingers.
  • Fig. 1 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in anterior imaging procedures.
  • Fig. 2 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in bitewing imaging procedures.
  • Fig. 3 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in posterior imaging procedures.
  • Fig. 4 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in endodontic imaging procedures.
  • Fig. 1 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in anterior imaging procedures.
  • Fig. 2 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in bitewing imaging procedures.
  • Fig. 3 is a perspective view of a sensor holder according to the concepts of the present invention, and configured for use particularly in posterior imaging procedures.
  • FIG. 5 is a perspective view showing an exemplary step in removeably affixing a sensor having a connecting cable to a sensor holder according to the present invention, and showing a support arm supporting both the inventive holder and a collimator ring for environmental purposes.
  • Fig. 6 is perspective view showing another exemplary step in removeably affixing a sensor to an inventive holder as in Fig. 5 and being sequential to the step of Fig. 5.
  • Fig. 7 is perspective view showing another exemplary step in removeably affixing a sensor to an inventive holder as in Fig. 5 and being sequential to the step of Fig. 6.
  • Fig. 8 is a perspective view of another embodiment of the invention.
  • FIG. 9 is a perspective view of another embodiment of the invention.
  • Fig. 10 is a perspective view of another embodiment of the invention.
  • FIG. 11 is a perspective view of another embodiment of the invention.
  • Fig. 12 is a perspective view of another embodiment of the invention.
  • Fig. 13 is a perspective view of another embodiment of the invention.
  • Fig. 14 is a perspective view of another embodiment of the invention.
  • a sensor holder 10 according to the present invention is shown by way of example on the drawing figures and is generally designated by the number 10. While the invention has application to any digital dental sensor, holder 10 is particularly adapted for use with sensors of the type having connecting cable. For environmental purposes, an exemplary sensor is shown on the drawings (Figs. 5-7) and is generally designated by the number 11. Sensor 11 is connected by an attached cable 12 to a peripheral device (not shown) of some kind, such as a computer or the like. Although the present invention has application to any shape or size of sensors, the invention is exemplified herein with reference to a sensor having a generally rectangular configuration, such shape being standard in the industry.
  • holder 10 is preferably provided with a bite block 13 of any configuration.
  • holder 10 is provided with an upstanding frame 20, preferably affixed to or formed contiguously with bite block 13.
  • upstanding it is meant that frame 20 is positioned at some angle to bite block 13.
  • bite block 13 will be held by a clamping action caused by the patient biting upon the bite block itself.
  • the bite block 13 is at least somewhat parallel to the patient's occlusal plane (not shown).
  • the upstanding frame is positioned to image either an upper or lower arch target site. An angle of about 90 degrees is often suitable although not necessarily a limitation of the present invention.
  • Frame 20 preferably bounds or delimits a void area 21.
  • An exemplary frame 20 includes a base frame member 30 which is positioned proximate to bite block 13.
  • Two spaced and opposed side frame members 31 and 32 extend from base frame member 30 and may be joined by a distal frame member 33.
  • frame members 30, 31, 32 and 33 lie in a similar plane.
  • At least one frame member carries a resilient latch finger 40.
  • side frame members 31 and 32 are shown to carry opposed latch fingers 50 and 51 respectively.
  • resilient it is meant that fingers 50 and 51 can move slightly with respect to their respective frame members in a resilient manner.
  • fingers 50 and 51 are each provided with means to accept a sensor 11 in a snap-fit relation, and thereby to receive a sensor cooperatively therebetween.
  • an exemplary finger 50 is shown as having a base portion 60 and at least one curved portion 61 contiguous therewith. It is preferred though not necessary that base portion 60 and curved portion 61 be integrally formed with the rest of holder 10.
  • finger 51 has a base portion 62 and a curved portion 63.
  • curved portion it is meant that base portions 60 and 62 are positioned at some angle with respect to their respective curved portions 61 and 63. The angle can be sharp or curvilinear and can be any suitable angle.
  • a pair of fingers 50 and 51 are positioned in an opposing spaced relation as discussed above, such that curved portions 61 and 63 are inwardly directed toward each other. Because fingers 50 and 51 are resilient, fingers 50 and 51 can receive a sensor 11 therebetween by slightly flexing and away from each other due to physical contact with the sensor 11. Once the sensor 11 has traveled sufficiently between fingers 50 and 51, curved portions 61 and 63 "close” upon sensor 11 and hold sensor 11 therebetween.
  • any number of fingers such as fingers 50 and 51 can be employed. For example, it is possible that only one finger is used wherein it is carried by distal frame member 33; base frame member 30 may also carry a finger similar to finger 50 or 51; or all frame members may carry similar fingers (these embodiments not being shown).
  • frame 20 and its frame members such as frame members 30, 31, 32 and 33 preferably bound or delimit a void area 21.
  • frame members 30, 31, 32 and 33 preferably bound or delimit a void area 21.
  • the invention is preferred and exemplified with a complete frame around void 21, it is not necessary that frame 20 completely surround void area 21 (this configuration not being shown but which will be understood).
  • the inventive configuration of void 21 and frame 20 is such that when a sensor is so secured in place by said latch fingers, the connecting cable is positioned through said void area (Figs. 5-7).
  • a sensor 11 with a connecting cable 12 is inserted through frame 20 void area 21 from a side opposite the operational side of the holder 10 when sensor 11 is held therein for use.
  • the operational side of the holder 10 when sensor 11 is held therein for use it is meant that the sensor has a side 70 which is positioned to receive x-ray energy during an imaging procedure and a side 71 opposite side 70 which normally carries an attachment point 72 for cable 12.
  • the side of sensor 11 that receives x-ray energy in use is the operational side of sensor 11.
  • the operational side of the holder 10 when sensor 11 is held therein for use is the same side when sensor 11 is received and held in holder 10.
  • sensor 11 when sensor 11 is inserted through void area 21, cable 12 trails behind and through void area 21. At this point, sensor 11 can be turned an rotated if needed, such that it properly aligns with frame 20 and fingers 50 and 51 (Figs. 6-7). It will also be appreciated that the steps of turning or rotating are not necessarily required. Once sensor 11 is properly aligned it is physically received by and snap-fit into place by fingers 50 and 51 as above described. It is to be appreciated that when sensor 11 is so positioned and held by holder 10, cable 12 is also secured and positioned by being held within void area 21. Thus the cable 12 is out of the way or at least in a known position for the patient and the dental professional during an imaging procedure. [0030] For environmental purposes, holder 10 is shown in Figs. 5-7 as being affixed to a support arm 100 and a collimator ring 101 as it would be in actual use during an imaging procedure.
  • Figs. 1 and 3 show holders 10 suitable for use in imaging procedures for anterior and posterior positions respectively.
  • Fig. 4 shows a holder 10 suitable for use in endodontic procedures wherein a bite block is formed by first and second spaced and opposing legs 80 and 81. The space between legs 80 and 81 allows the placement and use of endodontic equipment such as files during the imaging procedure.
  • Fig. 2 shows a bitewing holder 10 and which also has a cable conduit 90 positioned thereon. It will be appreciated that according to the invention, conduit 90 is useful to position and secure a cable 12 during imaging procedures.
  • Figs. 8, 9 and 10 show a digital sensor holding device.
  • Said device designed to securely retain, centrally align, and perpendicularly align said sensor to an x-ray source.
  • Sensor retention by means of tension pinch applied by integrated and opposing clamping arms of sufficient distance apart. Perpendicular alignment by means of this pinch in conjunction with making the contact surface of the clamping arms a sufficient length.
  • Assembly of the sensor facilitated by means of a flex slot between said clamping arms which allows the unit to dynamically overcome the clamp arm tension pinch without putting excessive loading on said sensor.
  • Central alignment of said sensor to the x-ray source facilitated by means of a stiffening rib to minimize deflection of the holding device relative to an attached alignment bar and ring.
  • Cord retention of said sensor by means of an integrated cord clip.
  • FIGs. 11 and 12 show a radiographic imaging medium holding device. Said device designed to securely retain multiple sizes of x-ray film, phosphor plate, or similar medium in the same device. Medium retention by means of two or more pairs of slots of sufficient distance apart to capture by friction a variety of industry standard sizes of said medium.
  • a typical use of this invention would be to facilitate the capture of optimally aligned digital dental radiography images.
  • Figs. 13 and 14 show a holding device designed to accommodate thin materials of varying thicknesses by means of an integrated dynamic pinching element.
  • Said pinching element configured in a flexible radial shape so as to isolate contact with the material to the tangent of the radius of the element.
  • Said radial element configured to facilitate the inserting and removing of material and to minimize surface damage to the inserted or removed material.
  • a typical use of this invention would be to facilitate the use of x-ray film or x-ray phosphor plates in radio graphical imaging. Another possible application would be the securing of developed x-ray film to an inspection light box.
