Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method of adding a cleaning liquid to root canals, periodontal pockets, etc. in order to clean extremely narrow gaps such as root canals and periodontal pockets in dental treatment. The present invention relates to a dental ultrasonic cleaning tool that makes it possible to clean and remove foreign substances and stains inside root canals, periodontal pockets, etc. by transmitting ultrasonic vibrations to the cleaning liquid.

[Conventional technology and problems]

Conventionally, root canals, periodontal pockets, etc. have been cleaned by using a syringe or a syringe, or by wrapping absorbent cotton around a cleanser and soaking it with a medicinal solution. However, the root canal is a narrow and deep hole, and the periodontal pocket is sealed by the gingiva, and the gap between the gums and the gums is narrow, making it impossible to enter the narrow gap with a syringe, and even with a needle, the root canal cannot be inserted into the narrow gap. Only injecting a cleaning solution into the tip of the tube does not cleanse it, so cleaning these areas is difficult and requires a long time, or cleaning is insufficient and the treatment effect is not fully achieved. In addition, some scalers have a structure in which a tip is fixed to the tip of an ultrasonic vibrator, and a flow path passing through the tip has a cleaning liquid spout opening at the tip of the tip. Generally, these tips are thick and have a curved shape that does not deform in most cases, so they cannot be used in root canals. Microscopic crystals in the cleaning solution mixed with other medicinal ingredients often block the flow path of the chip, and each time the chip needs to be replaced and reattached to the ultrasonic vibrator, which is extremely troublesome work. However, there were problems that made it impossible to put it into practical use.

[Means for solving problems]

The present invention was completed as a result of research aimed at providing means for solving the above-mentioned conventional problems.

That is, in the present invention, the rear end of the tip holder is fixed coaxially to the tip of the ultrasonic transducer built into the housing, and a tip made of a metal thin tube is attached to the tip of the tip holder. Dental ultrasonic cleaning, characterized in that the tip is replaceably installed intersecting the axial direction of the tip, and a flexible cleaning liquid receiving tube for connecting to a cleaning liquid supply source is attached to one end of the tip. It's about the ingredients.

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is an explanatory sectional view of the main parts of one embodiment of the dental ultrasonic cleaning tool according to the present invention, and FIG. 2 is an overall external view.

In the drawings, reference numeral 1 denotes an ultrasonic transducer, which is housed in a housing 2. The ultrasonic transducer 1 generally includes a cone and a horn attached to an ultrasonic transducer body, and in the present invention, these are collectively referred to as the ultrasonic transducer 1. Reference numeral 3 designates a tip holding portion, the rear end of which is coaxially fixed to the front end of the ultrasonic transducer 1 as shown in FIG. This fixing is preferably done by screwing as shown in the figure, as it makes the fixing or removal work easier, but screws or the like may also be used. Preferably, the tip is positioned in the opening of the housing 2. 4 is a tip consisting of a thin tube made of metal such as stainless steel, and the outer diameter is 0.3++ to make it suitable for dental treatment.
It is preferable that it is thin with a thickness of about m to 1.0+nm, has a protrusion length of about 10 mm to 50 mm from the chip holding part 3, and has cuts at both ends substantially perpendicular to the length direction. As shown in FIG. 2, the tip 4 is replaceably attached to the tip of the tip holder 3 so as to intersect with the axial direction of the tip holder 3. Depending on the relationship between the insertion direction of the tip 4 into the affected area and the axial direction of the grip portion, that is, the housing 2, the crossing angle is preferably substantially perpendicular to the axial direction or intersects with the axial direction at an appropriate angle. One embodiment in which the tip 4 is removably attached to the tip of the tip holder 3 is that a large through hole 5 is bored at the tip of the tip holder 3, and a chuck 6 is inserted into the large through hole 5. This is the case if it is installed.

An example of this embodiment will be explained with reference to FIG. 1. The large through hole 5 has a female threaded portion 5a extending from one end to the center, and a conical hollow portion 5b that is continuous with the female screw portion 5a and opens at the top to the outer wall on the opposite side. The chuck 6 has a male threaded portion 6.
It consists of a conical portion 6b divided into two to four parts, and a small through hole 6c through which the chip 4 can be inserted is bored at the axial position. To attach the chip 4 to the chip holder 3 in the above embodiment, first insert the chuck 6 from the conical part 6b into the large through hole 5, align the conical part 6b with the conical hollow part 5b, and screw the male threaded part 6a into the female thread. After inserting the tip 4 into the plate to the extent that it forms part 5a, the tip 4 is inserted into the small through hole 6c by an appropriate length, and the chuck 6 is further screwed in to tighten it completely. By doing so, the divided pieces of the conical portion 6b are pushed toward the axis and grip the chip 4 firmly. This chip 4 is manufactured as a continuous long piece, and when used, the ultrasonic vibration frequency, the size and shape of the chip holder 3, the size and shape of the chip 4 and the chip holder 3, and the
Angle of intersection with.

It is only necessary to take various conditions such as the diameter of the chip 4 into consideration and cut it to an appropriate length. At one end of the tip 4, that is, the end on the side that is not inserted into the affected area (hereinafter referred to as the cleaning liquid inlet side), there is a flexible cleaning liquid receiving tube 7 for connecting to a separate cleaning liquid supply source 9, as shown in FIG. installed. The cleaning liquid inlet side of the chip 4 is connected to the chip holding part 3 as shown in the figure.
It is preferable to bend the tip along the outer wall of the tip because it facilitates the manipulation of the tip 1 and the positioning of the tip 4 in the oral cavity. A cord 8 for connecting to the ultrasonic oscillation circuit is attached to the rear part of the housing 2, and is controlled by a foot switch (not shown) attached to the ultrasonic oscillation circuit side as necessary. The cleaning liquid supply source 9 may be a conventional type, and the cleaning liquid supply source 9 may be supplied separately from this ultrasonic cleaning tool using a foot switch or the like, or it may be connected to a foot switch attached to the ultrasonic oscillation circuit side. You can also do it.

〔how to use〕

Connect the cleaning liquid receiving tube 7 of the above-mentioned dental ultrasonic cleaning tool to the cleaning liquid supply source 9, insert the tip 4 inside the root canal or periodontal pocket, etc., and after receiving the cleaning liquid, the tip of the tip 4 The cleaning liquid is sprayed from the root canal or periodontal pocket, and while the cleaning liquid is added to the inside of the root canal or periodontal pocket, the tip 4 applies ultrasonic vibration to this cleaning liquid to clean foreign objects and dirt inside the root canal or periodontal pocket. .

[Action and effect]

The dental ultrasonic cleaning tool according to the present invention uses a metal thin tube as the tip 4 and attaches it to the tip holding part 3 in a crosswise manner, so that it can be easily inserted into the deep part of a root canal or periodontal pocket. As the ultrasonic waves are transmitted to the tip 4, the cleaning liquid added inside the root canal or periodontal pocket is given ultrasonic vibrations from the tip 4, and the entire affected area inside the root canal or periodontal pocket, etc. can be cleaned thoroughly and in a short time. Moreover, the metal layer thin tube that can be mass-produced as the chip 4 is appropriately cut in consideration of the optimum conditions for ultrasonic vibration and is attached to the chip holder 3 in a replaceable manner, so that crystals in the cleaning solution can be removed. If the tip 4 is blocked due to.

It can be easily and inexpensively replaced with a new chip 4.
