Description

  TECHNICAL FIELD The present invention relates to an instrument with a camera, and more particularly, with a camera in which a camera unit is mounted on an instrument main body that can be operated by hand to facilitate the sterilization (autoclave) processing of the instrument main body. It is about instrumentation.

  For example, in the case of dental instruments such as scalers, handpieces, and photopolymerizers that are often used in the field of dental treatment, it is possible to observe the treatment area with high-quality images and from the viewpoint of hygiene. The simplicity of the sterilization (autoclave) treatment to be performed is extremely important.

  Conventionally, various instruments with a camera for realizing observation of an image of a treatment site have been proposed.

  For example, in Patent Document 1, a diagnosis or treatment using a treatment tool provided in a periodontal examination treatment tool is performed via a diagnosis of a periodontal portion or an image of a treatment part using a micro camera attached to the examination or treatment tool. Thus, a periodontal examination treatment tool with a camera, which is configured to be able to conduct examination or treatment, is disclosed.

In the periodontal examination treatment tool with a camera of Patent Document 1, since the camera and the cable of the camera are exposed to the outside of the handpiece, the visual field of the operator is obstructed, and the tip of the handpiece becomes complicated. And included problems in terms of usability.
In addition, a small camera, which is a high-priced part, is provided at the tip, but when performing sterilization (autoclave) processing, the small camera is temporarily removed or sterilization means other than autoclave such as chemical treatment is used. Had to do.

  In Patent Literature 2, a handpiece body in which a cutting tool is attached to the head portion and a light receiving port is provided in the vicinity of the cutting tool, a grip portion that is detachably connected to the handpiece body, A camera built-in handpiece having a small camera module built in the handpiece body is disclosed.

  In the case of the handpiece with a built-in camera disclosed in Patent Document 2, a photographing optical system in which a camera module is built in the tip of a grip portion housed in the handpiece body and an optical transmission body such as a rod fiber is used up to the tip of the handpiece head. Is used.

  Therefore, when the handpiece body is sterilized, the camera module is not sterilized, but an image of the treatment site is transmitted using an optical transmission body having a certain optical path length. However, it is difficult to obtain an image having high resolution image quality.

  Patent Document 3 includes a photopolymerization LED, a CCD sensor, and a half mirror prism that transmits light from the photopolymerization LED and refracts and reflects an image of an observation site to guide the CCD sensor. In addition, a photopolymerizer with a camera is disclosed in which a photopolymerization resin is cured by light from the LED, and an image of an observation site is picked up by the CCD sensor.

  However, although the photopolymerizer with a camera of Patent Document 3 has both a function of curing the photopolymerization resin and a function of imaging the observed portion, an LED, a CCD sensor, and a half are provided in the photopolymerizer body. It is a configuration with a built-in mirror, and does not take into account the simplicity of sterilization (autoclave).

The imaging surface formed by the condensing lens 73 faces the position of the opening 68 so as to face the diagnostic region, and the camera side connector 77 faces the rear end side of the camera unit loading / unloading guidance area 69. Instead, the connecting cylinder portion 67 is attached to the probe 62 itself, and the camera side connector 77 and the connector 70 are electrically connected.

  Thereby, when performing a dental pulp diagnosis of a patient by the electric dental pulp diagnosing device 1F, an image of the diagnosis part is taken by the camera unit 71, and the image is acquired to improve the reliability of the dental pulp diagnosis. Can be stored in memory.

  Further, by detaching the camera unit 71 from the probe 62, the probe 62 can be sterilized (autoclave) easily without damaging the function of the camera unit 71, which is a high-priced part. The sterilization (autoclave) process of the probe 62 can be simplified.

  Further, the probe 62 functions as a cover body of the camera unit 71 and exhibits the protective function of the camera unit 71, which is a high-priced part, as in the fifth embodiment.
