Hot and cold pen device for oral diagnosis and treatment and uses thereof

Abstract

The invention discloses a hot and cold pen device for oral diagnosis and treatment. The device includes a main body and a working part which is arranged at an end part of the main body, and also includes a regulation button and a control switch which are arranged on a surface of the main body. The main body is also provided with a control system, a regulation system, a refrigeration circuit and a heating circuit therein. The control system and the control switch are connected, and the control switch turns on and off the control system, and the control system controls the refrigeration circuit and the heating circuit to work. The regulation system is connected to the regulation button, and sets temperature through the regulation button, and transmits a regulation temperature signal to the regulation system. The regulation system and the control system are connected, and the control system receives the regulation temperature signal which is output by the regulation system and controls the refrigeration circuit and the heating circuit to work to a set temperature. According to the invention, the cold and hot pen device can accurately regulate temperature of a cold and hot stimulus source, and controls variation of cold and hot temperatures and temperature constancy, and is characterized by convenience, safety, and low error rate.

Description

technical field [0001] The invention relates to the technical field of dental aids, in particular to a cold and hot pen device for oral cavity diagnosis and treatment and its application. Background technique [0002] At present, with the improvement of living standards, people's awareness of oral health care continues to increase, objectively putting forward higher requirements for stomatologists, and at the same time, there is an increasing demand for oral diagnosis and treatment equipment and instruments. [0003] In the process of oral diagnosis and treatment, it is often necessary to perform operations such as pulp vitality test, root canal filling with gutta-percha, cutting off the gutta-percha, taking out the gutta-percha or root canal fixation screw path pretreatment. [0004] Dental pulp is the soft tissue located in the pulp cavity, which is surrounded by hard tissues such as dentin and enamel, and has important physiological functions. When there are external sti...

AI Technical Summary

Problems solved by technology

The popsicle method is easy to operate, but the water will flow to the adjacent teeth, which will affect the judgment. It melts quickly in hot weather, so it is not suitable for operation

The method of injecting cold water with a syringe needs to use a rubber tent to isolate the affected tooth, which not only increases the operation of the rubber dam, but also increases the cost; when the affected tooth is uncertain, or several adjacent teeth may be affected teeth, the operation is time-consuming and laborious

The carbon dioxide snow method is inconvenient to use

There is also a hot gutta-percha injection method, which requires special equipment, which will cause overfilling, high cost, high technical requirements for operation, and limited wide application and promotion.

[0010] In the prior art, in the cold and hot diagnosis test of pulp vitality test and the hot gutta-percha filling method of root canal treatment, there are still large errors in cold and hot temperature adjustment and control, and the constant temperature control effect is poor, which is easy to cause misdiagnosis, Missed diagnosis affects the doctor's judgment on the patient's condition, and there is also a hidden danger of harm to the patient
