Problems solved by technology

The diameter and length of the transducer in the existing ultrasonic scaler are relatively large (generally 10-12mm in diameter and 28-34mm in length), although it can meet the performance requirements in the actual operation process, but due to the The large size of itself and the characteristics that the transducer must be installed inside the handle will inevitably make the size of the final product handle larger, thus affecting the feel and maneuverability of the handle

Embodiment Construction

[0021] Such as Figure 1~3 As shown, the ultrasonic scaler transducer with optimized structural size of the present invention includes a coaxially connected horn 1, a piezoelectric ceramic 2 and a main rod 3, and the horn 1 includes a piezoelectric ceramic 2 The round table 1-1 coaxially connected, the anti-rotation body 1-2 coaxially connected with the round table 1-1 and the working tip connecting rod coaxially connected with the anti-rotation body 1-2, the total of the horn 1 The length is 27~29mm, of which:

[0022] The diameter of the round table 1-1 is 8-10 mm, and the distance from the upper end surface to the bottom end face of the horn 1 is 2-4 mm. An annular groove 1-5 is provided on the side of the round table 1-1, and the The groove is filled with silica gel to achieve better waterproof performance. The depth of the annular groove 1-5 is 0.1-0.4mm, and the width is 0.5-0.7mm;

[0023] The anti-rotation body 1-2 is a regular hexahedral prism, the distance between ...

Abstract

The invention discloses an ultrasonic dental descaler transducer with an optimized structural size. The ultrasonic dental descaler transducer comprises an amplitude transformer, a piezoceramic and a main rod which are connected in a coaxial manner; the amplitude transformer comprises a round platform, an anti-rotation body and a work tip connecting rod; the round platform is connected with the piezoceramic in a coaxial manner; the anti-rotation body is connected with the round platform in a coaxial manner; and the work tip connecting rod is connected with the anti-rotation body in a coaxial manner. The ultrasonic dental descaler transducer is characterized in that the overall length of the amplitude transformer ranges from 27 to 29 mm. Compared with the prior art, the ultrasonic dental descaler transducer has a small structural size, and the performances equal to a prior transducer with a larger size; in addition, the size of the ultrasonic dental descaler transducer is decreased, so that a handle that is equipped with the ultrasonic dental descaler transducer in an encapsulation manner becomes smaller, the handling property is good, and the hand feel is good.

Description

technical field [0001] The invention relates to an ultrasonic dental scaler, in particular to a transducer for an ultrasonic dental scaler with an optimized structural size. Background technique [0002] The transducer is the main part of ultrasonic medical equipment such as ultrasonic dental scaler. It is installed inside the handle and is usually divided into upper, middle and lower parts. Specifically, it is the upper horn, the middle piezoelectric ceramic and the lower main part. pole. The structural size of the transducer is closely related to the output characteristics such as tip vibration frequency and main vibration offset of the working tip. The diameter and length of the transducer in the existing ultrasonic scaler are relatively large (generally 10-12mm in diameter and 28-34mm in length), although it can meet the performance requirements in the actual operation process, but due to the The large size of itself and the fact that the transducer must be installed i...
