Standard instruments are the instruments used to examine, restore and extract teeth and manipulate tissues.

Reduced area imaging device incorporated within wireless endoscopic devices

A reduced area imaging device is provided for use in medical or dental instruments such as an endoscope. In a first embodiment of the endoscope, connections between imaging device elements and between a video display is achieved by hard-wired connections. In a second embodiment of the endoscope, wireless transmission is used for communications between imaging device components, and / or for transferring video ready signals to a video display. In one configuration of the imaging device, the image sensor is placed remote from the remaining circuitry. In another configuration, all of the circuitry to include the image sensor is placed in a stacked fashion at the same location. The entire imaging device can be placed at the distal tip of an endoscope. Alternatively, the image sensor can be placed remote from the remaining circuitry according to the first configuration, and control box is used which communicates with the image sensor and is placed remotely from the endoscope. Further alternatively, the imaging device can be incorporated in the housing of a standard medical camera which is adapted for use with traditional rod lens endoscopes. In any of the configurations or arrangements, the image sensor may be placed alone on a first circuit board, or timing and control circuits may be included on the first circuit board containing the image sensor. The timing and control circuits and one or more video processing boards can be placed adjacent the image sensor in a tubular portion of the endoscope, in other areas within the endoscope, in the control box, or in combinations of these location.

Dental instruments with stress relief

The present invention relates to a unique solution for relieving repetitive stress to dental professionals during the course of a day and is directed to sets of identical instruments, having handles made with varying diameters for grasping, designed to be used interchangeably throughout the day, thus cutting down on the repetitive grasping action through the change of grasp. Therefore, even if a dental professional uses the same type of instrument throughout the day, the hands, wrists and elbows can experience varying rather than repetitive action because the positioning of the hands, wrists and elbows are interchanging throughout the day. The dental instrument may also be ergonomically designed. Additionally, the instrument may also have a vibratory module. Further, a rotator may also be implemented.

Reduced area imaging device incorporated within wireless endoscopic devices

A reduced area imaging device is provided for use in medical or dental instruments such as an endoscope. The imaging device is provided in various configurations, and connections between the imaging device elements and a video display may be achieved by wired or wireless connections. A connector assembly located near the imaging device interconnects the imaging device to an image / power cable extending through the endoscope. The connector provides strain relief and stabilization for electrically interconnecting the imager to the cable. The connector also serves as the structure for anchoring the distal ends of steering wires extending through the body of the endoscopic device. The connector includes a strain relief member mounted over a body of the connector. The connector allows a steering wire capability without enlarging the profile of the distal tip of the endoscopic device.

Methods and apparatus for simulating dental procedures and for training dental students

A training system using haptically enhanced simulations of dental procedures to provide the sensorimotor involvement needed for dental training. To provide touch feedback in combination with a realistic visual experience, the system integrates a haptic stylus interface for simulating the movement and feel of the tool-tip with a three-dimensional, stereoscopic display. The haptic stylus enables the dental student to orient and operate simulated dental tools. Working on a virtual model viewed in a stereo display, dental students can use a simulated pick to probe a tooth, or a simulated drill to prepare a tooth for cavity repair. The touch feedback is simulated by representing these dental instruments as force-to-a-point tools which map to haptic simulation procedures executed on a computer workstation that also provides the visual display.

Method of manufacturing a dental instrument

Method for manufacturing a dental instrument having a desired machined configuration, without twisting the instrument. A blank of superelastic material is brought to an annealed state comprising a phase structure including a rhombohedral phase alone or in combination with austenite and / or martensite, or a combination of martensite and austenite. In this annealed state, a portion of the annealed material is removed at low temperature, for example less than about 100° C., and advantageously at ambient temperature, to form a final machined configuration for the instrument. The instrument is then heat treated and rapidly quenched to a superelastic condition.

Apparatus and method for particle feeding by pressure regulation

The invention enables accurate control of particle flow with regard to feeding abrasive material to a surface. The unit does not employ a vibrator and may be used to remove undesired material from a surface. A particular application is in a dental air abrasion unit for both cleaning and cutting tooth surfaces. When used in an air abrasion dental instrument, the abrasive material is stored in a container which is separated from a mixing chamber by an orifice member. The flow of particles is electronically controlled by the differential in pressure in the container section above the particle level and the pressure below an orifice member in a mixing chamber. The resulting particle flow to the surface is substantially linear and less erratic than that of prior air abrasion instruments.
