BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
In the present embodiment, a dental treatment unit used for dental treatment will be described as an exemplary form of an operator's chair on which an operator sits. The operator's chair will be mainly described for dentistry, but it can also be applied to any medical treatment such as ophthalmology, otorhinolaryngology, radiology, and veterinary medicine. Treatment also includes diagnosis and treatment.

In conventional dental practice, a patient sits on a chair for dental practice, and with the patient's upper body upright, the operator (dentist) twists the patient's body to look into the patient's oral cavity. However, it is a burden for the operator to perform medical treatment in an unnatural posture such as twisting the body, and there is a problem that the operator cannot achieve stable finger control and secure the visual field. there were. After that, an American dentist, Dr. Darryl R. At Beach's suggestion, a dental treatment unit was developed that enables horizontal treatment, in which the patient is placed horizontally and the operator sits behind the head.

The idea underlying the development of this dental treatment unit is a concept called "pd" ("proprioceptive derivation"), which means "deduction based on proprioception". In other words, it is a “human-centered design and layout”, and the idea is to provide a friendly medical environment for all people, including not only physical movement and flow lines, but also mental health.

The concept of "pd" was incorporated into the dental examination unit (especially the operator's chair) described in the present embodiment, and was developed. This enables the operator to maintain stable hand control and visual field. A dental treatment unit according to this embodiment will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the external configuration of a dental diagnostic unit. FIG. 2 is a schematic diagram showing the configuration of the appearance of the operator's chair.

As shown in FIG. 1 , the dental treatment unit 1 includes an operator's chair 10 , a treatment chair 20 (dental treatment chair), a basin unit 30 , and an illumination device 40 .

Moreover, although not shown, the dental treatment unit 1 includes functional units that perform various functions, and these functional units perform their functions based on the operator's operation. These functional units and the control unit that controls each functional unit include a CPU (Central Processing Unit) and memory (ROM (Read Only Memory) and RAM (Random Access Memory) (not shown) mounted on the board. ), etc.

As shown in FIG. 2, the operator's chair 10 is a chair that the operator sits on when performing medical treatment. ), a footrest 13 for supporting the operator's feet, a support section 14 for supporting the seat 12, casters 15 (rotating section) provided on the support section 14, and a tray table 16 ( medical tray), a foot controller 17, and a monitor 18 (display unit). The backrest 11, the seat 12, and the footrest 13 may be driven by a seat driving section (not shown). The operator's chair 10 may have a shape in which the operator sits on the seat 12 without the backrest 11 and the footrest 13 or a shape with the backrest 11 and the seat 12 .

Further, the support portion 14 has a structure in which a portion connected to the seat 12 supports the seat 12 rotatably. Therefore, the operator sitting on the seat 12 can freely change its orientation within a horizontal plane with respect to the floor surface. The structure for rotatably supporting the seat 12 may be any structure.

The casters 15 are provided on the support portion 14 on the side opposite to the side supporting the seat 12 . In other words, the operator's chair 10 is in contact with the floor via the casters 15 . Since the casters 15 have wheels that rotate, the seat 12 can be moved with respect to the floor. That is, the operator's chair 10 can be freely moved on the floor using the casters 15 .

The tray table 16 is used as a storage stand during medical treatment. The tray table 16 is connected to an arm 14a (tray moving mechanism) extending from the supporting portion 14 of the operator's chair 10, and is manually rotated and horizontally moved with respect to the operator's chair 10 within a predetermined range. , and can move vertically. FIG. 3 is a schematic diagram showing how the tray table 16 moves. It should be noted that the arm 14a may extend from the seat 12 instead of from the support portion 14 . That is, the tray table 16 may be attached to the seat 12 or the support portion 14 . Note that the tray table 16 may be detachable from the seat 12 or the support portion 14 .

A controller 16 a is provided on the bottom surface of the tray table 16 . A plurality of medical instruments 16b (dental medical instruments), an operation panel 16c, an instrument holder 16d, and a monitor 18 are connected to the control unit 16a. The control unit 16a performs control for driving these components.

The medical instrument 16b is an instrument used for medical treatment, such as an air turbine handpiece (high speed handpiece), a micromotor handpiece (low speed handpiece), a scaler, a three-way syringe, a vacuum syringe, and the like. The medical instrument 16b is not limited to these, and may be an intraoral camera, a photopolymerization irradiator, a root canal length measuring instrument, a root canal expander, or a non-driven instrument such as a mirror or a syringe. There may be.

For example, three types of medical instruments 16b are used. A high-speed handpiece (also called HS), a low-speed handpiece (also called LS), and a scaler (also called SC) are used as the medical instrument 16b. These medical instruments 16b are held by an instrument holder 16d. When the medical instrument 16b to be used is removed from the instrument holder 16d, the holding by the instrument holder 16d is released. When the holding of the medical instrument 16b is released by the instrument holder 16d, the medical instrument 16b is in a selected state.

A high-speed handpiece is, for example, an air turbine handpiece. The air turbine handpiece has a function of spraying water onto the heat-generating part to suppress the heat generated when cutting ivory, which is the enamel of teeth, and a function of spraying water or the like to blow away dust. Therefore, the air turbine handpiece includes a tube including a supply pipeline for supplying water, a discharge pipeline for discharging water, an air supply pipeline for supplying driving air, and an exhaust pipeline for discharging driving air. is connected. On the other hand, micro-motor handpieces and scalers, which are low-speed handpieces, do not require air supply lines for supplying driving air, but power supply wiring for supplying power and supply lines for supplying water are tubes. connected to

Thus, each medical instrument 16b is connected to a plurality of tubes 16e. The plurality of tubes 16e are connected to the control unit 16a and also connected to the air source and the water source. If the plurality of tubes 16e are arranged on the floor, not only will the operator's chair 10 be prevented from moving freely, but there is also a danger that the operator will stumble over the tubes 16e and fall.

Therefore, in the present embodiment, a penetrating portion is provided in the support portion 14 of the chair 10 for the operator, and a plurality of bundled tubes 16e are passed through the penetrating portion to prevent the chair 10 from moving freely. It is configured so that it does not occur. FIG. 4 is a schematic diagram showing how a plurality of tubes 16e pass through the through portion 14b provided in the support portion 14 of the chair 10 for the operator. As shown in FIG. 4, the penetrating portion 14b is provided in the support portion 14 so as to penetrate from the side of the seat 12 (the side facing the backrest 11) to the backrest 11 side. Therefore, the plurality of tubes 16e extending from the control portion 16a of the tray table 16 can be pulled out from the side of the backrest 11 from the backrest 11 side. The penetrating portion 14b may be provided in the support portion 14 so as to penetrate from one side surface of the backrest 11 to the other side surface. In this case, the plurality of tubes 16e can be pulled out from the side of the backrest 11 opposite to the tray table 16 through the through portion 14b. In this way, by providing the through portion 14b in the support portion 14 so that the bundled tubes 16e can be pulled out from the backrest 11 side of the seat 12 or the side surface of the seat 12, the side where the operator moves is provided. Since a plurality of tubes 16e are not arranged in the tube 16e, it is possible to reduce the risk that the operator or the like will trip over the tubes 16e and fall.

The control unit 16a drives each medical instrument 16b based on a user's operation received by the foot controller 17. FIG. For example, a cutting tool held in the head of the HS rotates under the control of the control unit 16a and can be used for dental treatment.
