Description

The present invention relates to a dental treatment unit.

As is well known, in dental treatment, the patient sits on the seat of a dental chair and leans his back against the backrest to receive treatment. The surgeon inverts the backrest to put the patient in a posture that is easy to treat, and performs treatment such as cutting teeth. A foot controller is usually installed on the floor surface on the backrest side with respect to the lower table that supports the seat surface, and the operator operates the dental treatment equipment such as a handpiece by the foot controller.

When operating the dental treatment chair, there is a risk that the patient may have an unexpected accident, and measures are provided to avoid this. For example, Patent Document 1 is provided with a sensor for detecting an intruding object, and detects an intruding object including a human body in a non-contact manner with respect to a gap generated by movement of a backrest or the like during attitude control, and the gap becomes particularly narrow. A dental chair unit that can prevent accidents in which the human body is sometimes pinched is disclosed.

Further, Patent Document 2 is provided with a camera for photographing a patient supported by a medical table, detects that the patient is in an abnormal posture other than the originally intended posture, and is between the backrest and the seat surface of the medical table. There is disclosed a medical medical device capable of preventing a patient's hand or foot from being pinched or caught when a movable part is driven.

By the way, in dental treatment, an operator usually treats a patient who is seated in a dental treatment chair from the side having a backrest with respect to the lower table. However, if the backrest is tilted to make the patient easier to treat, it becomes a blind spot of the collapsed backrest, and the operator keeps the treatment position on the floor surface on the backrest side. The installed foot controller and the operator's own foot (particularly toe) that operates the foot controller cannot be visually recognized.

Therefore, the surgeon needs to temporarily break the treatment position and directly visually recognize the foot controller, and each time the backrest is tilted, the operator must frequently take his eyes off the patient, which reduces work efficiency. .. In order to avoid this, the surgeon searches for the foot without changing the treatment position, and when trying to identify the position of the foot controller by the feel of the foot, the foot controller makes an incorrect operation due to a mistake in pressing the switch. There was a risk of doing this, and there was a problem in ensuring the accuracy and safety of the treatment.

In recent years, as the number of treatment opportunities using a microscope has increased, a monitor has been installed near the dental treatment chair at a position visible to the operator, and the monitor includes dental treatment including images of the microscope. The necessary information can be displayed. In the treatment using a microscope, the surgeon often performs the treatment while keeping the posture fixed, and there is an increasing demand for a technique that can confirm the position of the foot controller only by moving the line of sight without changing the treatment posture. However, both the dental chair unit described in Patent Document 1 and the medical medical treatment device described in Patent Document 2 prevent accidental accidents of a patient seated on a medical table provided with a movable part and ensure its safety. It improves, but does not solve these problems.

The present invention has been made in view of such a situation, and it is possible for the operator to confirm the position where the foot controller and his / her own foot are placed only by moving the line of sight without disturbing the treatment posture. Its purpose is to provide a dental treatment unit.

In order to solve the above problems, the invention of claim 1 is a dental treatment chair provided with a seat surface, a backrest foldably attached to the seat surface, and a lower base supporting the seat surface, and a monitor. A dental treatment unit having a foot controller for operating a dental treatment device, a camera having a camera on a part of the outer surface of the dental treatment chair, and an image taken by the camera. The monitor displays, and the camera captures the relative positional relationship between the foot controller installed on the floor surface on the backrest side with respect to the lower platform and the feet of the person who operates the foot controller so as to be discriminating. When the backrest starts to fall down from a substantially upright state, the monitor displays an image captured by the camera .

The invention of claim 2 is characterized in that, in the invention of claim 1, the camera is provided on the back surface side of the backrest or the side surface of the lower table on the backrest side.

The invention of claim 3 is characterized in that, in the invention of claim 1 or 2 , when the operation by the foot controller is started, the image displayed by the monitor is switched to an image other than the image captured by the camera. It is to be.

The invention of claim 4 is the invention of claim 1 or 2 , wherein the image displayed by the monitor is switched to an image other than the image captured by the camera by an operation other than the operation by the foot controller. It is a feature.

According to the present invention, the image taken by the camera provided in a part of the dental treatment chair allows the operator to only move the line of sight while maintaining the treatment position even if the foot controller is in the blind spot of the backrest. You can check the position of the foot controller and your own foot with, and concentrate on the treatment without lowering the work efficiency. At the same time, search for the foot controller with the feel of your feet and try to operate it to prevent erroneous operation. It is possible to prevent and fix the treatment position by using a microscope or the like.

Hereinafter, preferred embodiments of the dental treatment unit of the present invention will be described with reference to the drawings. In the following description, it may be assumed that the members with the same reference numerals are the same in different drawings, and the description thereof may be omitted.

FIG. 1 is an overall view of the dental treatment unit 10 according to an embodiment of the present invention. The dental treatment unit 10 has a dental treatment chair 20, a foot controller 30, and a monitor 40, and the dental treatment chair 20 is rotatably attached to the seat surface 22 and the seat surface 22. It is provided with a backrest 21 and a lower base 23 for supporting the seat surface 22. The foot controller 30 is usually installed on the floor surface on the backrest 21 side with respect to the lower base 23, and is via a unit control system (not shown) and a connection cable 31 built in a part of the dental treatment unit 10 such as the lower base 23. Be connected. The connection between the foot controller 30 and the unit control system is not limited to such wired communication, and may be configured without a connection cable 31 by using wireless communication using infrared rays or the like.

On the back side of the backrest 21, a range including a part of the foot controller 30 and a part of the operator's foot (at least the toe part) trying to operate the foot controller 30 when the backrest 21 is tilted is photographed. The camera 24 is provided at a position where the camera 24 can be used. If the range can be photographed, the position where the camera 24 is provided is not limited to the back side of the backrest 21, but may be, for example, the side surface of the lower base 23 on the backrest 21 side.

A water supply / drainage box 60 having a shadowless lamp 61 and a spitton 62 is installed on the left hand side of the lower stand 23 when viewed from the patient seated on the seat surface 22, and a monitor 40 is located below the support column that movably supports the shadowless lamp 61. An arm 42 is attached to support the arm 42. The arm 42 has a movable portion, and the monitor 40 attached to the tip of the arm 42 can be moved to a position where the operator can easily check it. However, the monitor 40 may be installed at a position where it is easy for the operator to check by itself, instead of being supported by the arm 42.

FIG. 2 is a diagram showing a state in which the monitor 40 included in the dental treatment unit 10 according to the embodiment of the present invention displays the foot controller 30 and a part of the operator's foot. Originally, when the monitor 40 displays the image captured by the camera 24 as it is, the captured image 41 is inverted 180 degrees, and the operator's foot is displayed on the upper part of the screen in a left-right inverted state. However, in such an image, it becomes difficult for the operator to move his / her eyes to the monitor 40 and instantly grasp the relative positional relationship between the foot controller 30 and his / her own foot.

Therefore, the monitor 40 reverses the image captured by the camera 24 when the backrest 21 is raised by 180 degrees and displays the foot controller 30 so that the switch of the foot controller 30 comes to the lower part of the screen of the monitor 40. The relative positional relationship between the 30 and the operator's foot is made easier for the operator to grasp. Such a display can be realized electronically by image processing, but it is physically achieved by simply installing the camera 24 on the back side of the backrest 21 or the like, contrary to the vertical position when the backrest 21 is erected. It can also be realized.

Further, as described above, the captured image 41 is sufficient as long as the operator can grasp the relative positional relationship between the foot controller 30 and his / her own foot. For example, the camera 24 is used for wide-angle imaging. A fisheye lens may be provided, and the captured image 41 may be displayed in a distorted manner as a whole, or may be highlighted in some way in order to facilitate confirmation by the operator.

FIG. 3 is a block diagram of a system configuration for monitor display in the dental treatment unit 10 according to the embodiment of the present invention. First, it is assumed that the image data taken by the microscope imaging device 51 through the microscope 50 used by the surgeon is transmitted to the image switching interface 12 in the dental treatment unit 10 and output to the monitor 40. explain. The image displayed on the monitor 40 when the backrest 21 is standing may be information necessary for other dental treatment such as an roentgen image.

In the present embodiment, when the backrest 21 stands up, the image data taken by the camera 24 attached to the back side of the backrest 21 or the like is also transmitted to the image switching interface 12, but at this point, it is output to the monitor 40. Not done. However, the camera 24 may not be operated when the backrest 21 is upright, and the camera 24 may be operated when the backrest 21 is tilted.

Then, when the unit control system 11 detects that the backrest drive unit (not shown) has started the operation of tilting the backrest 21, the unit control system 11 transmits an image switching signal to the image switching interface 12 and receives the signal. The image switching interface 12 switches the image output to the monitor 40 to an image based on image data captured by the camera 24. The unit control system 11 transmits an image switching signal to the image switching interface 12 when it detects that the backrest 21 has fallen to a certain angle from the same state even immediately after it starts to fall from a substantially upright state. It may be.

When the operator operates the foot controller 30 in this state, the foot controller 30 transmits a foot controller input signal to the unit control system 11, and the unit control system 11 that receives the signal sends an image switching signal to the image switching interface 12. Send. Upon receiving the signal, the image switching interface 12 switches the image output to the monitor 40 to an image based on the image data captured by the original microscope photographing device 51.

Further, in an emergency or the like, when it is necessary to switch the image output to the monitor 40 to an image based on image data other than the image data taken by the camera 24 without waiting for the operator to operate the foot controller 30. There is also. In that case, switching of the image output to the monitor 40 by an operation other than the operation by the foot controller 30 may be possible by a switch or the like (not shown). The image data other than the image data captured by the camera 24 has been described on the premise of the image data captured by the microscope photographing device 51, but this is merely an example and is not limited thereto.

FIG. 4 is a side view of the dental treatment unit 10 according to the embodiment of the present invention, showing the state before and after the backrest 21 is tilted up and down. As shown in the figure, when the backrest 21 is substantially upright and the patient 70 is in a state of being able to stand up from the dental treatment chair 20, the operator 71 can visually recognize the positions of the foot controller 30 and his / her feet. ..

On the other hand, once the backrest 21 is tilted so that the surgeon 71 can easily treat the patient 70, a blind spot is created by the backrest 21, and the surgeon 71 does not lose the treatment posture and the foot controller 30. And you will not be able to see the position of your own foot.

However, since the camera 24 provided on the back side of the backrest 21 can capture a range of blind spots, the surgeon 71 moves his / her eyes to the monitor 40 while maintaining the treatment posture. The position of the foot controller 30 and its own foot can be confirmed only by itself.

As described above, in the dental treatment unit, the operator is in a treatment position even if the foot controller is in the blind spot of the backrest by the image taken by the camera provided in a part of the dental treatment chair. You can check the position where the foot controller and your own foot are placed by just moving your eyes while keeping the above, and you can concentrate on the treatment without lowering the work efficiency, search for the foot controller with the feel of your feet, and operate it. It is possible to prevent the occurrence of erroneous operation by trying the above, and to cope with the immobilization of the treatment position by using a microscope or the like.
