Problems solved by technology

[0003] Among the existing root canal treatment instruments, some treatment instruments have a reciprocating rotation mode. At this time, the motor of the root canal treatment instrument drives the file part of the root canal treatment instrument to rotate in reverse and forward direction in turn; some treatment instruments have a dental gear motor It also has the dual function of root apex locator and real-time monitoring and alarm function. However, the root canal treatment instruments in the prior art only have one or two functions. If you want to realize the operation of multiple functions, On the other hand, multiple instruments need to be used together, the operation is complicated and troublesome to use

Embodiment 1

[0081] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0082] Such as Figure 1-Figure 11 A root canal motor measuring treatment instrument shown includes a main handle (1) and a deceleration bender (2), wherein,

[0083] The main handle (1) is provided with a control unit (11) and a motor (31), and the main handle (1) is provided with a display screen (12), and the head of the main handle (1) is connected to a deceleration bending machine (2); Described control unit (11) comprises motor control unit (111), CPU (112), root canal test unit (113), and described motor control unit (111), root canal test unit (113) and CPU (112) connect;

[0084] The deceleration bending machine (2) is provided with a deceleration ...

Embodiment 2

[0098] The root canal motor measuring therapeutic instrument can be set to enter the root canal length test mode. The operation steps include:

[0099] The CPU (112) transmits signals of different frequencies to the measuring part, and reads signals of different frequencies at the same point of the root canal from the measuring part to measure the impedance value, and compares the impedance value reaching the position of the apical foramen according to the measured impedance value;

[0100] The CPU (112) reads the different frequency signals from the measuring part in real time to measure the impedance value from the needle tip of the expanding needle to the same point of the root canal, and compares the ratio and difference of the measured impedance value with the preset value at the position of the apical foramen, and calculates The distance between the tip of the enlarged needle and the position of the root tip of the tooth is calculated, and then the result is sent to the d...

Embodiment 3

[0102] The root canal motor measurement therapy instrument can be set to enter the root canal length test and current monitoring mode. The operation steps include:

[0103] The CPU (112) sends a forward working command to the motor, so that the motor rotates in the positive direction, and at the same time, the CPU sends signals of different frequencies to the measuring part, and detects the current value passing through the motor while the motor is rotating;

[0104] The CPU (112) reads the impedance value of different frequency signals at the same position of the root canal when the motor is running from the measuring part, and compares the impedance value reaching the position of the apical foramen according to the measured impedance value;

[0105] judging whether the measured impedance value is close to a predetermined range, and if it is greater than the predetermined range, keep sending a forward working instruction to the motor; and

[0106] Judging whether the current ...

Abstract

The invention discloses a root canal motor measurement therapy apparatus. The root canal motor measurement therapy apparatus is characterized by comprising a main machine handle and a speed-reducing bending machine, wherein the main machine handle is internally provided with a control unit and is externally provided with a display screen; the head of the main machine handle is connected with the speed-reducing bending machine; the control unit comprises a motor control unit, a CPU (Central Processing Unit) and a root canal testing unit; the motor control unit and the root canal testing unit are connected with the CPU. According to the root canal motor measurement therapy apparatus, a measurement function in the root canal therapy apparatus and an operation function of a motor are integrated; the motor is intelligently controlled to operate in a measurement process, and an operation mode is converted into a reciprocating motion mode when the motor meets great resistance in an operationprocess and the motor reaches a root tip position; then the motor is automatically stopped or is inversed to an inversion mode so that automatic starting, automatic speed reduction, automatic stoppingand automatic inversion functions of the motor are realized; a 'root measurement function' root canal preparation function, an automatic root canal preparation function and a reciprocating rotation function at present are integrated, so that root canal therapy is more intelligent and automatic.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a root canal motor measuring instrument. Background technique [0002] In international oral treatment, root canal treatment is the most commonly used treatment method for pulp disease and periapical disease. The principle of root canal therapy is to remove most of the infected matter in the root canal by mechanical and chemical methods, carry out proper disinfection, and prevent the occurrence of periapical disease or promote the occurrence of periapical disease by filling the root canal and sealing the crown. sickness healing. Root canal therapy is a very effective means to treat pulp necrosis, apical inflammation, irreversible pulpitis, etc. and to preserve the affected teeth. Root canal treatment instrument, also called root canal motor, is used for root canal treatment in dentistry. It is a precision instrument for removing diseased root canal nerves and trimming...
