JPH11188051A - Cleaner for tooth surface and interproximal space - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a good cleaner that can remove dental plaque, stain, nicotine and so on from tooth surfaces and interproximal spaces for dentists. SOLUTION: Cleaner 10 for dental surface consists driving shaft 11 and electromagnetic converter 12 that comes arid goes toward the direction of arrow A along the shaft 11. At the top of the driving shaft 11, blade 13 for cleaning interproximal spaces is mounted as it can rub on dental surfaces, while it can freely be attached to or detached from the driving shaft 11. The driving shaft is drawn toward the one direction of the shaft when direct current pulse voltage 16 is applied through lead wire 15, and then, a spring is expanded or constricted, so energy can be accumulated in the spring. As electric pulses are lessen, the driving shaft 11 returns to the starting position by the energy accumulated in the spring. As a result, driving shaft 11 can come and go toward the direction of the arrow A.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic diagram of a main portion for explaining an embodiment of a tooth surface cleaning tool according to the present invention.
10 is a tooth surface cleaning tool according to the present invention.
Means handpiece I, joint II, hose III
The hose unit III is connected to a control unit provided in a dental treatment unit (not shown) or a dedicated control unit for the present tooth surface cleaning tool, and is provided with a manual operation provided in the handpiece unit I. Or a foot controller (not shown).

The tooth surface cleaning tool 10 has a drive shaft 11 and an electromagnetic converter, preferably a push-pull solenoid (manufactured by Shindengen Co., Ltd.) 12 for driving the drive shaft 11 to reciprocate in the direction of arrow A. At the tip of the drive shaft 11, a tooth surface cleaning blade 1 is moved while being in contact with the tooth surface to clean the tooth surface.
3 is detachably mounted. The tooth surface cleaning blade 13 may be directly attached to the drive shaft 11. However, since the tip of the drive shaft 11 is used by being inserted into the oral cavity of a patient, the drive shaft 11 is used. 1
It is necessary to disinfect (preferably, autoclave) the tip portion of each patient. For this reason, a tip 14 for relay is detachably provided at the tip of the drive shaft 11, and the blade 13 is detachably attached to the tip 14 for relay. The blade 13 is preferably disposable, but when used repeatedly, for each patient, the relay tip 14 is removed from the drive shaft 11 together with the relay tip 14, or remains integral with the relay tip 14 or the relay tip 14, and may be autoclaved together with the relay chip 14.

When a DC pulse voltage 16 is applied to an electromagnetic converter (push-pull solenoid) 12 via a lead wire 15 by operating a hand-operated switch or a foot controller (not shown), the drive shaft 11 is moved in the axial direction. At that time, a spring (not shown) is pulled by being extended or compressed, and energy is stored in the spring. When the pulse disappears, the drive shaft 11 returns to its original position by the energy stored in the spring, and this is repeated each time the pulse arrives, and consequently,
The drive shaft 11 is reciprocated in the direction of arrow A. At this time, the reciprocating cycle, stroke, and the like of the drive shaft 11 can be changed by the cycle, amplitude, and the like of the pulse voltage 16.

FIG. 2 is a schematic diagram showing a main part of another embodiment of a tooth surface cleaning tool according to the present invention.
Reference numerals A and 12B denote push-pull solenoids each having the same function as the push-pull solenoid 12 described in the embodiment shown in FIG. 1. In the present invention, a plurality of push-pull solenoids (two in the illustrated example) are provided. 1.) The cascade connection is the same as that of the embodiment shown in FIG. Thus, if a plurality of push-pull solenoids are provided in cascade, the driving force differs between when only one is driven and when a plurality (for example, two) are driven simultaneously. By switching between the case of using one unit and the case of using a plurality of units as necessary, it is possible to widen the used power range,
A more convenient tooth surface cleaning tool can be provided.

As described above, the tooth surface cleaning tool according to the present invention applies the blade 13 to the tooth surface and reciprocates the blade 13 to remove plaque, stain, tar, tartar, etc. fixed to the tooth surface. If the blade 13 is hard, the teeth are damaged by the blade 13. Therefore, a soft material is used as the material of the blade 13 so as not to damage the teeth. Further, in the present invention, since the push-pull solenoid is used as the electromagnetic converter, the reciprocating stroke of the blade can be increased as compared with ultrasonic vibration or the like, eliminating the need for manual reciprocating movement. A cleaning tool with very good workability can be provided. Needless to say, fine vibration (ultrasonic vibration) may be applied to the drive shaft 11 additionally.

The rotary solenoid 22 is connected to the lead 2
The drive shaft 21 is driven by a DC pulse voltage 26 supplied through the motor 5 to reciprocate the drive shaft 21 in the direction of arrow B (the return operation uses a spring to store a force when going forward and uses the energy stored in the spring). A thin blade 23 is detachably attached to the tip of the drive shaft 21. This is similar to the embodiment shown in FIG.
It may be attached via a blade attachment tip 24 which is detachably attached to the drive shaft 21.

As described above, in the inter-tooth cleaning tool 20, the blade 23 is formed in a thin plate shape and reciprocates around the drive shaft 21, so that the blade 23 is inserted between the teeth. Then, when the drive shaft 21 is driven, the blade 23 reciprocates between the teeth, and the adhered matter adhered to the tooth surface between the teeth can be removed. Further, the rotary solenoid (made by Shindengen Co., Ltd.) 22 has a structure that converts the force into a linear force and a rotary motion. The tooth surface is brought into contact with the tooth surface and the tooth surface between the teeth can be more effectively cleaned.
