Referring to FIG. 1, an automatic switching dental treatment apparatus 10 according to the present invention includes a medical treatment unit, a suction unit 200 for suction, a difference between parameters of the medical treatment unit and the suction unit 200, And a control unit 300 for controlling the driving.

The medical examination unit is a device for diagnosing and treating the condition of the teeth, and a scaler, a drill handpiece, and the like can be applied.

In this embodiment, a scaling unit is described as an example of a medical treatment unit for explaining the structure of the present invention, taking an ultrasonic scaler that removes calculus by applying ultrasonic waves. Of course, the medical treatment unit is not limited to the scaling unit, and all the medical care means combining the dental operation tool with the handpiece including the drill can be applied.

The scaling unit 100 includes a handpiece 120 to which the scaler tip 110 and the scaler tip 110 are connected.

The scaler tip 110 is for removing dental plaque between the teeth and between the teeth and the gums, and is detachably coupled to the handpiece 120. The scaler tip 110 is replaced with a consumable part as the end of the tip wears as the scaling progresses.

The scaler tip 110 is formed of a conductive material so that a difference or a change of a parameter with the suction unit 200 can be detected in a control unit 300 described later.

In addition, the handpiece 120 is formed so that the operator can grasp the scissors in the process of scaling. Although not shown, a switch or a button for operation may be provided. And a signal transmission unit formed of a conductive material so as to be electrically connected to the scaler tip 110 (not shown).

The suction unit 200 includes a suction tip 210 and a suction pipe 220 coupled to the suction tip 210. The suction unit 210 sucks body fluid or scaling water used for scaling by the suction unit 200, .

The suction tip 210 is opened at an end thereof to suck body fluids and wash water, and the body fluid or the wash water sucked through the suction pipe 220 connected to the suction tip 210 moves. The suction pipe 220 may be formed of a flexible synthetic resin material so as to be bent.

In addition, the suction pipe 220 is provided with a shape holding member 230 extending along the pipe. The shape retaining member 230 may cause the suction unit 200 to be hooked to the mouth portion of the recipient or to bend the body fluid or the wash water in the corner portion of the mouth to facilitate suction. When the suction pipe 220 is bent, the suction pipe 230 is maintained in a bent shape so that the bending shape of the suction pipe 220 can be maintained.

For this, the shape holding member 230 is formed of a conductive material so as to be able to sense the difference between the parameters of the suction unit 200 and the scaling unit 100, . In order to satisfy such a condition, the shape retaining member 230 may be any one selected from the group consisting of copper, aluminum, a cobalt alloy, and an aluminum alloy.

The shape retaining member 230 having a predetermined diameter is in a state where one end of the shape retaining member 230 is in contact with the body fluid or the wash water when the suction tip 210 is in contact with the suction tip 210 in the vicinity of the suction tip 210, And is connected to the inner wall of the suction pipe 220 and extends to the lower end of the suction pipe 220 along the suction pipe 220. The shape retaining member 230 may be adhered to the inner wall of the suction pipe 220 through an adhesive and a separate coupling pipe through which the shape retaining member 230 can be inserted may be formed on the inner wall of the suction pipe 220 It is possible.

The control unit 300 senses a difference or a change in parameters between the suction unit 200 and the scaling unit 100 and controls the driving of the scaling unit 100 through the detection.

Here, the parameter difference may be a difference between any one of a resistance, an inductance, a capacitance, and an impedance formed between the scaler tip 110 and the suction tip 210. In this case, the reference range is a range for a difference between any one of the resistance, inductance, capacitance, and impedance that may appear when the scaler tip 110 contacts the teeth and the suction tip 210 contacts the inside of the mouth .

If the scaler tip 110 is not in contact with teeth, gums, or the like, the impedance difference between the scaler tip 110 and the suction tip 210 may be infinite. The impedance difference between the scaler tip 110 and the suction tip 210 becomes smaller than infinity when the scaler tip 110 contacts the teeth or the gums with the suction tip 210 in contact with the inside of the mouth. The controller 300 can read the change in the impedance difference when the scaler tip 110 is changed from a state in which the scaler tip 110 is not in contact with teeth, gums, or the like to a contact state, or vice versa.

The reference range may be set to correspond to the type of parameter sensed by the controller 300 as a reference for operating the scaler tip 110 and the suction tip 210. Therefore, when the controller 300 senses the impedance difference between the scaler tip 110 and the suction tip 210, the reference range may be set to an impedance difference value.

For example, when the scaler tip 110 contacts the tooth or the gum with the suction tip 210 in contact with the inside of the mouth, the impedance difference formed between the scaler tip 110 and the suction tip 210 is 2M If it is below Ohm, it can be set as the reference range.

Since the impedance is represented by the combined effect of resistance, inductance, and capacitance, even when the type of the parameter difference sensed by the controller 300 is resistance, inductance, and capacitance, the impedance can be implemented similarly to the implementation example of impedance described above.

For example, if the parameter difference sensed by the controller 300 is a resistance difference, if the scaler tip 110 is not in contact with a tooth or a gum, the resistance difference between the scaler tip 110 and the suction tip 210 is infinite The resistance difference between the scaler tip 110 and the suction tip 210 becomes smaller than infinity when the scaler tip 110 contacts the tooth or the gum with the suction tip 210 in contact with the inside of the mouth .

If the controller 300 determines that both the suction tip 210 and the scaler tip 110 are in contact with the tooth or gum through the difference in parameters between the suction tip 210 and the scaler tip 110, The generator 310 is operated to apply the ultrasonic vibration to the scaler tip 110. At the same time, the water injection driving unit 320 is driven so that the washing water can be supplied while the scaling progresses.

Referring to FIGS. 2 and 3, the suction unit 200 further includes a switching unit 240.

The switching unit 240 is configured to limit the driving of the scaling unit 100 by preventing the control unit 300 from sensing a difference or a change in parameters between the suction tip 210 and the scaler tip 110.

The switching unit 240 includes a main body 241 formed at the lower end of the suction piping 220 and a switching unit 240 installed at an end of the suction piping 220. The switching unit 240 includes a main body 241, A connecting member 243 connected to the rotating shaft 242 and connected to or separated from the shape holding member 230 in accordance with rotation of the rotating shaft 242, And an operation lever 245 installed to be connected to the rotation shaft 242 on the outer side and rotating the rotation shaft 242 such that the connection member 243 is connected to or separated from the shape holding member 230.

The main body 241 is connected to the drain line so that the body fluid and the wash water flowing through the suction pipe 220 can be moved to the drain line, and a flow path is formed in the body 241 at the lower end of the suction pipe 220.

A rotation shaft 242 is formed in the main body 241. The rotation shaft 242 extends across the inside of the main body 241 and is supported by the main body 241 at both ends thereof.

The operating lever 245 is connected to the rotating shaft 242 and can rotate the rotating shaft 242 in the forward or reverse direction by moving the operating lever 245 up and down.

The connection member 243 is formed on the rotation shaft 242. The connection member 243 includes a shape holding member 230 extending to the lower end of the suction pipe 220 in accordance with the rotation direction of the rotation shaft 242, And can be separated from the shape retaining member 230. [

The connection member 243 is formed of a conductive material and connected to the control unit 300 through a signal transmission line 246. Therefore, when the connection member 243 contacts the shape holding member 230, when the suction tip 210 is in contact with the tooth or gum in the state where the suction tip 210 is positioned in the mouth of the controller 300, Lt; / RTI >

The connection member 243 contacts the shape holding member 230 and the suction tip 210 of the suction unit 200 is positioned in the oral cavity The resistance is infinite while the scaler tip 110 is not in contact with the tooth or the gum. However, when the scaler tip 110 comes into contact with the tooth or the gum, the resistance is lowered so that the controller 300 senses a change in resistance . At this time, the controller 300 applies ultrasonic vibration through the ultrasonic generator 310 and supplies washing water.

Conversely, when the connecting member 243 is separated from the shape holding member 230 by rotating the rotating shaft 242 through the operating lever 245, the driving of the scaler unit is restricted in a state in which the resistance becomes infinite. In this case, even if the scaler tip 110 is brought into contact with the tooth or the gum, the shape retaining member 230 and the connecting member 243 are separated from each other, so that the resistance difference sensed by the control unit 300 does not change, I never do that.

Thus, the driving of the scaler unit can be restricted even if the scaler tip 110 contacts the tooth or the gum through the switching unit 240. The switching unit 240 may be used when it is necessary to contact a tooth with a scaler tip without ultrasonic vibration in order to confirm the internal state of the teeth or the mouth during the scaling procedure.

4, a retaining groove 231 is formed in the shape retaining member 230 to maintain the engaged state of the connecting member 243 and the shape retaining member 230 and a retaining groove 244 is formed in the connecting member 243 May be formed.

In this process, the connection member 243 and the shape retaining member 230 may be in contact with each other regardless of the intention of the operator. The connection member 243 and the shape retaining member 230 can be firmly coupled through the retaining groove 231 and the retaining ring 244 in order to prevent such unintentional separation .

In the automatic switching dental treatment apparatus 10 according to the present invention, the ultrasonic vibration is automatically applied only by bringing the scaler tip 110 into contact with the teeth or gums without using the foot switch, and the washing water is sprayed, A scaling procedure can be performed.

In particular, when the ultrasonic vibration and the washing water are not sprayed when the scaler tip is brought into contact with the tooth or the gum, the driving of the scaling unit 100 can be simply restricted through the switching unit 240 installed in the suction unit 200 Effective dental care and management can be achieved.

The shape retaining member 230 is electrically connected to the control unit 300 when the shape retaining member 230 is coupled to the terminal connection unit 252 by being coupled to the suction pipe 220, 210 < / RTI > and the scaler tip.

When the detachable member 251 is separated from the suction pipe 220, the switching unit 250 of the present embodiment releases the connection between the shape retaining member 230 and the terminal connection unit 252, and even if the scaler tip contacts the tooth or the gum, .
