Description

[Detailed description of the invention] The treatment table used in dental clinics etc. has two types of handpieces, one for high speed and one for low speed, for cutting teeth, and these two handpieces are movable by being suspended from the ceiling or side wall. It was locked to the side edge of the tray.

However, since the handpiece holder is attached to a movable tray, it is rarely in a fixed position and moves with the tray, making it difficult for the operator to visually check where the handpiece is during treatment. If the device is far away, it must be pulled to a nearby location and fixed in place, making it difficult to perform medical treatment using consistent, natural hand movements.

In this invention, the handpiece locking means is separated from the tray and fixed directly to the treatment table so that it is always held in a constant position.This allows the surgeon to always use a constant hand movement to hold the handpiece. The tray can be easily handled, improving work efficiency, and the tray can be carried freely separately from the handpiece, making it possible to quickly clean up after the work is completed.

An embodiment of the present invention will be described below based on the drawings.
Reference numeral 1 designates a treatment table whose upper surface is a substantially horizontal plane, 2 a headrest attached to one side of the table, 3 a light that illuminates the patient's oral cavity from above, and a support for the treatment table, which is approximately L. The lower end of the letter-shaped frame 4 is locked to a support 5 attached to one bent portion of the treatment table 1 on the headrest side.

Reference numeral 6 denotes a ring-shaped tray support fixed to the lower end of the L-shaped frame 4, and a holder 7 is integrally provided on the upper surface of the ring-shaped tray support.
One side of the tray 8 is inserted between the ring-shaped tray support 6 and the holder 7, and is locked by its own weight.

Reference numeral 9 denotes a handpiece locking means provided at the lower part of the tray support, which includes a support rod 10 that protrudes laterally from the lower end of the L-shaped frame 4, and upper and lower 2 that are attached to the tip of the support rod 10.
It consists of a locking tool 11 having an engaging portion at the step.

The upper retaining part 11a of the locking tool 11 locks the high-speed handpiece 12, and the lower engaging part 1lb locks the low-speed handpiece 13, with their tip working points facing the treatment table 1 side. For the operator located between the headrest 2 and the handpiece locking means 9, the lower end retaining part 11
b is closer to the upper engaging portion 11a than the upper engaging portion 11a, and is designed to make it easier to take out the respective handpieces 12 and 13.

And the cord 12' of each of these handpieces 12, 13
, 13' are drawn out from the side edge of the treatment table where the headrest 2 is provided.

In addition, switches 14 are protruded from the bottom of each of the upper and lower stages of the locking tool 11, and when one of the high and low handpieces used for work is taken out, the switch on the side from which the handpiece was taken out is turned on, and the handpiece is turned on. Operates automatically.

Therefore, the foot switch 15 has two separate pedals for high-speed and low-speed operation as in the past, and there is no need to press the corresponding pedal depending on the handpiece that is taken out to operate it. However, since it is automatically activated by the switch 14, only one pedal is required, and depending on the handpiece taken out, if the speed is high, water will be sprayed out just by pressing the pedal, and if the speed is low, the water will be spouted by pressing the same pedal. This enables high-speed rotation in the handpiece for use.

Further, in the figure, 16 indicates a vacuum, and 17 indicates a syringe.

Note that the handpiece locking means 9 is not limited to being fixed to the lower end of the L-shaped frame as in the above embodiment;
It may be made to protrude from the side or bottom of the treatment table 1.

In this way, the dental treatment table of the present invention is provided with a removable tray locking means on one bent part of the treatment table on the side where the headrest is provided, and one end of the tray locking means is attached to the side of the tray locking means. Since the fixed handpiece locking means is designed to hold two types of handpieces, one for high speed and one for low speed, with a step above and below, it is difficult to separate the handpiece from the tray and it is uniquely attached to the side of the treatment table. This makes it possible to lock it in a fixed position.

Since the handpiece is thus always held in a fixed position, the operator can take out the high-speed and low-speed handpieces from the optimal position for treating the patient's oral cavity using only natural hand movements.

Moreover, since the handpiece locking means has a step above and below, each handpiece can be easily taken out, and the handpiece held by the locking means is near the tray, and other handpieces placed on the tray can be easily removed. Since it is approximately parallel to the treatment instruments, the hand can be moved in the same direction and at the same angle as when using other treatment instruments, reducing the degree of fatigue even during long hours of work.

Furthermore, since each handpiece operates seven times when it is taken out from its respective locking part, only one foot switch is required to perform the functions of spouting water and switching between high and low speeds.
Operability using the foot is simplified and safer treatment is possible.

Furthermore, since the tray itself is configured to be detachable from the tray locking means, when the work is finished, the tray can be removed from the locking means and carried to the washing section with the treatment instruments on it, allowing the instruments, etc. The time required to clean up can be shortened and work can be done efficiently.
