[Embodiment 1]
In the first embodiment, an example of a medical system in which the drive amount corresponding to the received operation is limited to the upper limit value or less on the operation side such as the foot controller or the operation panel will be described. The overall configuration of the medical system 1000 will be described with reference to FIG. FIG. 1 is a schematic diagram showing the overall configuration of the medical system 1000 according to the first embodiment. The medical system 1000 includes a medical device 1, a patient camera 52, an overall camera 53, and a setting device 800. The medical system 1000 is a dental medical care system used in the dental field, and supports an operator's operation so that the driving amount of the medical device 1 can be appropriately controlled at the time of medical care in dentistry.

"Practice" includes at least one of medical examination and treatment. "Medical examination" includes the surgeon searching for the patient's dental condition and etiology. "Treatment" includes at least one of the surgeon curing a patient's dental illness and the surgeon maintaining the beauty and health of the patient's teeth (aesthetic treatment).

The medical device 1 is, for example, a dental care device. The medical device 1 includes a chair 11, a basin unit 12, a tray table 13, an instrument holder 14 for holding a medical instrument 15, a foot controller 16, a display 17, an operation panel 18, and a lighting device 19. ..

The chair 11 is a chair on which the patient sits during medical treatment. The headrest 11a that supports the patient's head, the backrest 11b that supports the patient's back, the seat seat 11c that supports the patient's tail, and the footrest that supports the patient's feet. Includes 11d. The chair 11 is configured so that the inclination can be changed. The driving state of the chair 11 (the degree of inclination of the chair 11) is transmitted to the setting device 800.

The baseon unit 12 is a water supply / drainage device including a pot 12a in which a drainage port is formed, a cup stand 12b on which a cup is placed, and a water tap 12c for supplying water to the cup.

The tray table 13 is used as a storage table for medical treatment. The tray table 13 is connected to a chair 11 or an arm extending from the floor on which the chair 11 is installed. The operator can manually rotate, move horizontally, and move the tray table 13 relative to the chair 11. During medical treatment, the surgeon may place the tray 30 on the upper surface of the tray table 13. The tray 30 is loaded with one or more instruments for treating the patient, such as tweezers, mirrors, excavators, and deep needles, which are used during the procedure by the surgeon.

The medical device 15 is a dental medical instrument such as an air turbine handpiece, a micromotor handpiece, an ultrasonic scaler, and a vacuum syringe, and is driven in response to an operation received by the foot controller 16. The driving state of the medical device 15 (rotational speed of the medical device 15) is transmitted to the setting device 800.

The foot controller 16 has a plurality of switches (pedals) that receive the stepping operation of the operator. The surgeon can assign a predetermined function to each of these plurality of switches. For example, the surgeon can assign the function of driving the medical device 15 to the switch of the foot controller 16, and when the foot controller 16 accepts the stepping operation of the switch by the surgeon, the driving corresponding to the stepping operation is performed. The medical device 15 is driven by the amount.

The display 17 is attached to the tray table 13 and displays various images (for example, an image of the oral cavity of a patient undergoing medical treatment).

The operation panel 18 includes a chair 11, a lighting device 19, a valve 123 (see FIG. 2), and a switch for setting the operation of the medical device 15. For example, when the operation panel 18 receives an input operation for operating the chair 11, the chair 11 operates based on the input operation. For example, when the operation panel 18 accepts an input operation for adjusting the brightness of the lighting device 19, the brightness of the lighting device 19 is switched based on the input operation. For example, when the operation panel 18 accepts an input operation for adjusting the drive amount (opening degree) of the valve 123, the opening degree of the valve 123 is switched based on the input operation. For example, when the operation panel 18 accepts an input operation for setting the rotation speed of the medical equipment 15, the rotation speed of the medical equipment 15 is set based on the input operation. For example, when the operation panel 18 accepts an input operation for setting the drive mode of the medical device 15 (ON / OFF mode, follow-up mode, assist mode, which will be described later), the drive mode of the medical device 15 is set based on the input operation. Set.

The lighting device 19 is provided at the tip of the arm 6 branching at the upper part of the chair 11 or the pole 5 extending from the floor on which the chair 11 is installed. The lighting device 19 can switch the brightness between a lighting state and a lighting state in a plurality of stages, and supports medical treatment by an operator by lighting. The driving state of the lighting device 19 (brightness of the lighting device 19) is transmitted to the setting device 800.

By using the medical device 1 configured as described above, the surgeon can perform dental treatment to the patient. In order to perform appropriate medical treatment, the surgeon needs to appropriately drive the medical device 1 such as the medical device 15, the chair 11, the lighting device 19, and the valve 123. Specifically, the surgeon drives (rotates) the medical device 15 at an appropriate speed, tilts the chair 11 at an appropriate angle, adjusts the lighting device 19 to an appropriate brightness, and drives the valve 123 appropriately. There is a need. In the past, the extent to which the medical device 1 was driven was entirely left to the judgment of the surgeon, but the judgment of the surgeon is not always appropriate. Therefore, in the medical system 1000, the setting device 800 collects information related to the drive of the medical device 1, and provides a technique for controlling the drive amount of the medical device 1 based on the information.

The patient camera 52 is attached to the lighting device 19 and is arranged so as to capture a moving image or a still image of the patient's oral cavity. Normally, during medical treatment, the patient's oral cavity is illuminated by the lighting device 19, so that the patient camera 52 attached to the lighting device 19 can naturally take an image of the patient's oral cavity. The image of the patient's oral cavity taken by the patient camera 52 is displayed on the display 17. The patient camera 52 may be installed at any place as long as it can photograph the inside of the patient's oral cavity.

The whole camera 53 is attached to the upper part of the pole 5. The whole camera 53 is to capture at least an area including a medical treatment space for treating a patient, that is, a large area in the medical treatment space including at least the patient and an operator such as a dentist or a dental assistant as a moving image or a still image. Have been placed. Since the general camera 53 is attached to the upper part of the pole 5, it is possible to capture the behavior of the dentist, the behavior of the dental assistant, the facial expression of the patient, the state of the chair 11, and the state of the entire medical treatment space. When the dentist who is undergoing medical treatment is looking away, the driving amount of the medical equipment 15 is reduced or the driving of the medical equipment 15 is stopped. Therefore, the behavior of the dentist during medical treatment is an element in calculating the upper limit of the driving amount of the medical device 1. When the dental assistant operating the chair 11 or the like is looking away, the driving amount of the chair 11 is reduced or the driving of the chair 11 is stopped. Therefore, the behavior of the dental assistant is an element in calculating the upper limit of the driving amount of the medical device 1. Further, even when the patient is in pain, the driving amount of the medical device 15 is reduced or the driving of the medical device 15 is stopped. Therefore, the facial expression of the patient during medical treatment is also an element in calculating the upper limit of the driving amount of the medical device 1. If the inclination of the chair 11 does not suit the patient, the inclination of the chair 11 is adjusted. Therefore, the state of the chair 11 is also an element in calculating the upper limit value of the drive amount of the medical device 1. If the medical space is too dark, the brightness of the lighting device 19 is adjusted. Therefore, the state of the entire medical care space is also an element when calculating the upper limit value of the drive amount of the medical device 1. If the amount of water injected from the medical device 15 is not appropriate, the opening degree of the valve 123 is adjusted. Therefore, the image data taken by the whole camera 53 can be said to be "image information related to the driving of the medical device 1." The image taken by the whole camera 53 is captured by the setting device 800 and referred to when the setting device 800 calculates the upper limit value of the drive amount of the medical device 1. The entire camera 53 may be installed in any place as long as it can capture an area including at least a medical treatment space for treating a patient.

The setting device 800 drives the medical device 1 based on at least one of the drive state of the medical device 1 transmitted from the medical device 1 and the image information related to the drive of the medical device 1 taken by the overall camera 53. The upper limit of the amount is calculated, and the calculated upper limit is transmitted to the medical device 1. In the medical device 1, the foot controller control device 160 or the input control device 180, which will be described later, receives the upper limit value sent from the setting device 800. The foot controller control device 160 controls the drive amount of the medical device 15 based on the drive amount corresponding to the operation received by the foot controller 16 within a range not exceeding the upper limit value received from the setting device 800. The input control device 180 controls the drive amount of the chair 11, the lighting device 19, or the valve 123 based on the drive amount corresponding to the operation received by the operation panel 18 within the range not exceeding the upper limit value received from the setting device 800. do.

FIG. 5 is a flowchart showing the drive control of the medical device 15 according to the first embodiment. The process shown in FIG. 5 is a process performed by the foot controller control device 160, and is realized by the CPU executing a control program. The process shown in FIG. 5 is started when the power of the medical device 1 is turned on, and is repeated until the power of the medical device 1 is turned off.

First, the foot controller control device 160 (specifically, the specific unit 164) determines whether or not the operation has been accepted by the foot controller 16 (step S505). When the operation is accepted by the foot controller 16 (YES in step S505), the foot controller control device 160 (specifically, the specific unit 164) specifies the medical device 15 to which the drive is instructed and the drive amount thereof. (Step S510).

Next, the foot controller control device 160 (specifically, the generation unit 166) determines whether or not the upper limit value of the drive amount of the medical device 15 specified in step S510 has been received from the setting device 800 (step S515). .. The foot controller control device 160 receives the upper limit value of the drive amount of the medical device 15 specified in step S510, which is transmitted from the setting device 800. When the upper limit value of the drive amount of the medical device 15 specified in step S510 is received from the setting device 800 (YES in step S515), the foot controller control device 160 (specifically, the generation unit 166) performs the process. The process proceeds to step S520. On the other hand, when the upper limit of the drive amount of the medical device 15 specified in step S510 is not received from the setting device 800 (NO in step S515), the foot controller control device 160 (specifically, the generation unit 166). Moves the process to step S530.

In step S520, the foot controller control device 160 (specifically, the generation unit 166) has an upper limit of the drive amount (drive amount specified in step S510) corresponding to the operation received by the foot controller 16 received from the setting device 800. Determine if the value is exceeded. When the drive amount corresponding to the operation received by the foot controller 16 exceeds the upper limit value received from the setting device 800 (YES in step S520), the foot controller control device 160 (specifically, the generation unit 166). Moves the process to step S525. On the other hand, if the drive amount corresponding to the operation received by the foot controller 16 does not exceed the upper limit value received from the setting device 800 (NO in step S520), the foot controller control device 160 (specifically, the generation unit). 166) shifts the process to step S530.

In step S525, the foot controller control device 160 (specifically, the generation unit 166) generates a control signal instructing that the medical device 15 specified in step S510 is driven by the upper limit value received from the setting device 800. ..

After step S525 or step S530, the foot controller control device 160 (specifically, the communication unit 165) transmits the control signal generated in step S525 or step S530 to the instrument control device 150 (step S535).

After step S535, the foot controller control device 160 returns the process to step S505. The series of processes shown in FIG. 5 is repeatedly executed by detecting a predetermined cycle or a predetermined event unless the power of the medical device 1 is turned off.

When the drive amount corresponding to the operation received by the foot controller 16 exceeds the upper limit value of the drive amount sent from the setting device 800 by the series of processes shown in FIG. 5, the drive amount is from the setting device 800. It is set to the upper limit sent. On the other hand, if the drive amount corresponding to the operation received by the foot controller 16 does not exceed the upper limit value of the drive amount sent from the setting device 800, the drive amount corresponds to the drive received by the foot controller 16. Set to quantity. As a result, the driving amount of the medical device 15 is controlled to an appropriate driving amount that respects the intention of the operator.

Of the processes shown in FIG. 5, the "foot controller 16" is used as the "operation panel 18", the "medical device 15" is used as the "chair 11, lighting device 19, or valve 123", and the "device control device 150" is used. When the input control device 180 executes the process read as "control device 200", the drive amount of the chair 11, the lighting device 19, or the valve 123 is controlled to an appropriate drive amount that respects the intention of the operator. To.

Next, with reference to FIGS. 6 and 7, the motor handpiece 15a (see FIG. 2) is used as an example to determine how the driving amount of the medical device 15 changes when the above control is performed. explain. FIG. 6 is a diagram showing a transition of the rotation speed of the motor handpiece 15a when the drive mode is the ON / OFF mode in the first embodiment.

The transition of the value is shown, and the solid line shows the transition of the actual drive amount of the motor handpiece 15a when the above-mentioned control is performed.

With reference to FIG. 6, the ON / OFF mode is a mode in which the motor handpiece 15a reaches the maximum rotation speed as long as the foot controller 16 is depressed, regardless of the depression amount of the foot controller 16. From timing t0 to timing t1 and from timing t2 to timing t3, the drive amount of the motor handpiece 15a corresponding to the operation received by the foot controller 16 and the upper limit value of the drive amount sent from the setting device 800 are one. Therefore, the drive amount of the motor handpiece 15a is controlled by the drive amount of the motor handpiece 15a corresponding to the operation received by the foot controller 16. On the other hand, from timing t1 to timing t2, since the drive amount of the motor handpiece 15a corresponding to the operation received by the foot controller 16 exceeds the upper limit value of the drive amount sent from the setting device 800, the motor hand The drive amount of the piece 15a is limited to the upper limit value of the drive amount sent from the setting device 800.

With reference to FIG. 7, the follow-up mode is a mode in which the rotation speed of the motor handpiece 15a changes according to the amount of depression of the foot controller 16. From timing t0 to timing t1 and from timing t2 to timing t3, the drive amount of the motor handpiece 15a corresponding to the operation received by the foot controller 16 exceeds the upper limit value of the drive amount sent from the setting device 800. Therefore, the drive amount of the motor handpiece 15a is limited to the upper limit value of the drive amount sent from the setting device 800. On the other hand, from timing t1 to timing t2, since the drive amount of the motor handpiece 15a corresponding to the operation received by the foot controller 16 does not exceed the upper limit value of the drive amount sent from the setting device 800, the motor hand The piece 15a is driven by the driving amount of the motor handpiece 15a corresponding to the operation received by the foot controller 16.

Another drive mode of the medical device 15 is an assist mode. The assist mode is a mode in which the drive amount of the motor handpiece 15a is controlled according to the upper limit value of the drive amount sent from the setting device 800, and is a mode useful for an inexperienced operator. In the assist mode, the operator needs to keep stepping on the foot controller 16 to the maximum. As a result, the upper limit of the drive amount sent from the setting device 800 is equal to or less than the drive amount (maximum drive amount) of the motor handpiece 15a corresponding to the operation received by the foot controller 16. Therefore, in the assist mode, it is always The drive amount of the motor handpiece 15a is controlled according to the upper limit value of the drive amount sent from the setting device 800. Therefore, when the drive mode is the assist mode, the transition of the rotation speed of the motor handpiece 15a is the same as that of FIG.

When the drive amount corresponding to the operation received by the foot controller 16 exceeds the upper limit value received from the setting device 800, the foot controller control device 160 instructs to drive the medical device 15 with the received upper limit value. A control signal is generated, and the control signal is transmitted to the instrument control device 150. On the other hand, when the drive amount corresponding to the operation received by the foot controller 16 does not exceed the upper limit value received from the setting device 800, the foot controller control device 160 has a drive amount corresponding to the operation received by the foot controller 16. Generates a control signal instructing to drive the medical device 15 and transmits the control signal to the device control device 150.

Further, when the drive amount corresponding to the operation received by the operation panel 18 exceeds the upper limit value received from the setting device 800, the input control device 180 uses the received upper limit value as the drive unit (chair 11, lighting device). 19. Generates a control signal instructing to drive the valve 123), and transmits the control signal to the control device 200 (chair control device 110, light control device 190, or valve control device 120).
