FIGS. 5 to 7 relate to a fifth embodiment of the present invention. FIG. 5 is a plan view of an operating room during an endoscopic surgical operation viewed from above, and FIG. 6 is a medical equipment cart (A cart). 7A is a rear view, FIG. 7B is a side view, and FIG.
FIG. 2 is a block diagram showing a schematic configuration inside an A-cart.

In the fifth embodiment, a configuration example in the case of using two medical equipment carts will be described. As shown in FIG. 5, when performing an endoscopic surgical operation, for example, two A-carts 50 and B-carts 51 equipped with devices necessary for the operation are provided.
Place and use.

An A monitor 52 is mounted on the upper part of the A cart 50, and two carbon dioxide cylinders 13 are mounted. A B monitor 53 is mounted on the B cart 51. The A surgeon 54 holds the treatment tool in one hand and looks at the A monitor 52, and the B surgeon 55 has the endoscope and the treatment tool and has the B monitor 5.
Look at 3 and perform each procedure.

As shown in FIG. 6, the A-cart 50 has four wheels 14, a brake device 56 attached to the side of the wheels 14, a wheel driving device 15, which drives the wheels 14,
A speed detecting device 57 for detecting a moving speed of the A cart 50,
A speed control device 58 for controlling the wheel drive device 15 and the brake device 56 is provided. In addition, a start switch 59 electrically connected to the speed control device 58 by a cable and a stop switch 61 provided inside the handle 60 are provided on the upper rear part of the A-cart 50. Further, inside the root of the handle 60, a lateral force detector 58a for detecting a lateral force of the handle 60 is provided as shown by a broken line in the figure.

These wheel drive device 15, brake device 56, speed detection device 57, speed control device 58, start switch 59, stop switch 61, lateral force detection unit 58a
Are connected to each other and operate as shown in the schematic cross-sectional view of FIG. The configuration of other parts is the same as that of the above-described embodiment, and thus the same reference numerals are given and the description is omitted.

In this embodiment, when moving the A-cart 50, the operator grips the handle 60 on the back of the A-cart 50 and then turns on the start switch 59. At this time, the handle 60 grasps the lower side of the stop switch 61.

When the start switch 59 is turned on, a control signal is transmitted from the speed control device 58 to the wheel drive device 15, the wheel drive device 15 is operated, and the wheels 14 start to move.
When the A-cart 50 starts to move, the speed detecting device 57 detects the moving speed and always sends speed information to the speed control device 58. Then, the speed control device 58 activates the wheel driving device 15 if the moving speed is lower than the reference speed range, and activates the brake device 56 if the moving speed is higher than the reference speed range, so that the moving speed of the A-cart 50 is always constant. Adjust to be. If the moving speed is within the reference speed range,
Since the wheel drive device 58 and the brake device 56 do not operate, the operator can easily move or change the direction with a small amount of force by manually pushing the A-cart 50.

To urgently stop the A-cart 50 while moving, the operator turns on a stop switch 61 located above the inside of the handle 60. When the stop switch 61 is turned on, a control signal is transmitted from the speed control device 58 to the brake device 56, and the brake device 56 is operated.
Stops. To start again, the start switch 59 is turned on again.

When the A-cart 50 bends at a right angle during the movement, the operator applies a lateral force to the handle 60 to rotate the A-cart 50 by 90 °. At this time, the lateral force is detected by the lateral force detector 58a, and a detection signal is sent to the speed control device 58. Then, the speed control device 58 recognizes that the A-cart 50 bends and performs control to lower the reference speed range, thereby reducing the moving speed of the A-cart 50.

As described above, according to the fifth embodiment, the wheels are automatically driven when the cart starts or on an uphill, and the brake is activated on a downhill or a corner. Labor can be reduced significantly.
Furthermore, since the stop switch is provided, the cart can be stopped at any time, and the danger of colliding with an obstacle while the cart is moving can be reduced. Also, unlike moving all carts electrically, wheels are driven only when necessary, so that the operator can freely change directions and consume less power.

For example, in the portable electronic device disclosed in Japanese Patent Application Laid-Open No. H6-125899, a caster is provided on the main body of the device, and the operator can move the portable electronic device by pushing the handle on the back, and the handle can be moved. There is disclosed a configuration in which the caster can be braked and released by rotating the. However, in such a configuration, when applied to a medical device cart, when the cart becomes large and heavy, a large amount of power is required for movement, so that the operator requires a great deal of effort and at the same time, brakes on downhill. Since the speed is difficult and suddenly rises, there is a risk of collision with another device or a person.

On the other hand, in the configuration of the present embodiment, in the cart equipped with the medical equipment, the moving speed is controlled according to the situation to assist the operator, so that the labor for moving the cart can be reduced. At the same time, it is possible to prevent problems such as collisions during the movement.

FIG. 8 is a view showing a configuration of a medical device cart according to a sixth embodiment of the present invention, wherein (A) is a side view,
(B) is a sectional view near the bottom.

The A-cart 50a according to the sixth embodiment includes a fifth cart.
Is substantially the same as that of the embodiment of FIG.
Instead of the start switch 59 and the stop switch 61, a force amount direction detection area 62 for detecting the presence or absence of the force amount and the force amount direction by the operator is provided on the entire circumference of the A-cart 50a. The force direction detection area 62 is electrically connected to a speed control device 58, and the other components such as the speed detection device 57
This is the same as the embodiment. However, the wheel drive circuit 15 further has a function of changing the direction of the wheels 14.

In this embodiment, when moving the A-cart 50a, the operator presses the force direction detection area 62 of the A-cart 50a. Then, the application of the force and the direction of the force are detected by the force direction detection area 62, and a detection signal is sent to the speed control device 58. Speed control device 58
Sends a control signal to the wheel driving device 15 to start driving the wheel 14 and to change the direction of the wheel 14 in the force detection direction. Other speed control operations are the same as in the fifth embodiment. In addition, when the operator sets the force amount direction detection area 62,
If you release your hand from the speed control device 58, the brake device 5
6, the control signal is transmitted, and the brake device 56 operates.
The A-cart 50a stops automatically.

As described above, according to the sixth embodiment, the operator can start and change the direction of the cart simply by pushing lightly with his / her hand, thereby both reducing the labor of the operator and improving the operability of the cart. It is. Then, when the operator releases the hand, the cart stops automatically, so that danger such as collision can be reduced.

9 and 10 relate to a seventh embodiment of the present invention. FIG. 9 is a perspective view showing the configuration of the upper part of the A-cart, and FIG. 10 shows the use state of the cart during an endoscopic surgical operation. FIG.

In the endoscopic surgery, as shown in FIG. 5, the A surgeon 54 performs a procedure while looking at the A monitor 52, but the surgeon may change the position during the surgery. is there.
For example, when the surgeon B moves between the surgeon A and the A monitor 52 in FIG. 5, the surgeon A cannot see the monitor screen, which may be very dangerous. At this time, it is only necessary to move the A cart 50 so that the A monitor 52 can be seen. However, the operating room usually has other devices, and in many cases, the cart cannot be easily moved. Therefore, in the present embodiment, a configuration example of a mechanism that moves only the monitor so that the operator can always see the monitor screen even when the operator moves will be described.

At the upper part of the A cart 50, a monitor base 63 on which the A monitor 52 is mounted is provided.
Is a monitor arm 64 extended from the A-cart 50 body.
Supported movably. An infrared sensor 65 for detecting an operator position is provided on the front of the monitor table 63.
, And one ultrasonic sensor 66 for detecting an obstacle in the direction in which the monitor moves in the left and right sides.

The main body of the A-cart 50 is provided with an arm drive device 68 for driving the monitor arm 64 and an arm control device 67 for controlling the drive of the monitor arm 64. The infrared sensor 65 and the ultrasonic sensor 66 are
It is electrically connected to the arm control device 67 by a cable (not shown). The arm driving device 68 is also electrically connected to the arm control device 67.

FIG. 10 actually shows the monitor arm 6 in the operating room.
FIG. 4 is a diagram illustrating a state when the image pickup No. 4 is driven. Here, A
The surgeon 54 wears glasses equipped with an infrared light emitter 65a so that the position of the operator 54 can be detected from the infrared sensor 65 of the monitor base 63.

When the operator B is located in front of the cart A and the screen of the monitor A is covered, the line of sight from the operator A to the monitor 52 is blocked by the infrared sensor 65 of the monitor base 63. Then, an operator detection signal is sent to the arm control device 67. The arm control device 67 receives the operator detection signal, activates the arm driving device 68, drives the monitor arm 64 until the A surgeon 54 is detected by the infrared sensor 65, and controls the A monitor 52 to operate the A surgeon 54. Move to a position visible from At this time, the ultrasonic sensor 66
Informs the arm control device 67 of the presence or absence of an obstacle in the monitor movement direction by an obstacle detection signal, and the arm control device 67 moves the A monitor 52 in the direction without the obstacle.

As described above, according to the seventh embodiment, since the monitor screen is always observable without being interrupted by another operator, the operation can be performed safely. In addition, since only the monitor can be automatically moved when necessary, the labor required for a nurse or the like to move the monitor manually can be eliminated. Disappears.

For example, Japanese Patent Application Laid-Open No. Hei 2-226873 discloses a television screen direction control device in which the direction of a remote controller is identified and the television is rotationally driven. If there is an obstacle in the rotational direction, the rotational driving is performed. An obstacle detecting means for stopping is provided. However, in such a configuration, when applied to a medical device cart, when the screen of the observation monitor used during surgery is hidden, if there is an obstacle in the monitor rotation direction, the rotation drive stops, so the monitor screen remains hidden. It would be very dangerous because the procedure would have to be performed up to that point.

On the other hand, in the configuration of the present embodiment, a monitor base having a mechanism for automatically moving according to the position of the operator is provided on the cart, and the monitor base moves so as to avoid obstacles. Therefore, it is possible to prevent the monitor screen from being hidden, and at the same time, to prevent a problem of colliding with an obstacle.

The cart body 1a has a mode setting mechanism 105 that can select and operate a traveling mode such as a moving speed according to the use of the operator.
Are arranged.

When using the cart body 1a of the present embodiment, the traveling mode is first set by the mode setting mechanism 105 before traveling. As this traveling mode, when traveling relatively long distances such as movement between examination rooms,
Depending on the application, such as moving in a relatively narrow range at a very low speed, such as moving in an examination room, manually moving by an operator, or completely stopping without accepting any traveling commands, It has various modes such as "movement mode", "inspection room movement mode", "manual mode", and "complete stop mode".

For example, when the cart body 1a is moved between the examination rooms, the operator sets the traveling mode to the "inter-laboratory movement mode" by the mode setting mechanism 105. Then
When the cart main body 1a is oriented in the direction intended by the operator and a force is applied to the portion of the piezoelectric element 100 of the cart main body 1a, the wheel driving device 15 is operated by the control of the drive control unit 104 in response to the pressing operation, and 14 is driven, the cart body 1a starts to move in the direction in which the operator applies the force, as if pressed with a force several times greater than that, and gradually accelerates until reaching a certain speed within a certain safe range. Cart body 1
When a reaches a certain speed, the certain speed is maintained until a deceleration instruction by the brake operation from the operator is detected. It is assumed that such a series of traveling control is performed by the drive control unit 104.

When the “inspection room movement mode” is set by the mode setting mechanism 105, the cart body 1a
In order to prevent collision with nearby people or objects, the cart main body 1a is not driven except when the operator is touching the piezoelectric element 100, and the running speed is set to a minimum when driving the cart. The travel control is performed by the drive control unit 104. Thus, the cart main body 1a moves at a very small speed only when the operator is pressing the piezoelectric element 100. As described above, the “inspection room movement mode” is suitable as a traveling mode when it is desired to move at a very low speed in a limited range such as an inspection room.

When the cart body 1a is not desired to be moved at all, the "complete stop mode" may be selected, and when the cart moving operation is manually performed, the "manual mode" may be selected. In the “complete stop mode”, the drive control unit 1
04 is wheel 1 without accepting any driving commands from the operator.
4 is locked to completely stop the cart body 1a.
In the "manual mode", the drive control unit 104 sets the wheels 14 in a free state, and enables the cart body 1a to be moved by manual operation by an operator. When the cart body 1a is driven, charging is performed by connecting the battery 106 to a commercial power supply for a certain time in advance.

In this embodiment, as shown in FIG. 16, a plurality of piezoelectric elements 100 provided on the cart surface
In addition to detecting the amount of force applied to the cart body 1a by the operator, it is possible to recognize up to the moving direction of the cart body 1a intended by the operator as the vector sum of the force components in each direction. For this reason, the cart body 1a
The cart travels as if pressed by the operator. At this time, the cart body 1a is driven semi-automatically by the driving assistance of the wheel driving device 15, so that the amount of force pushing the cart body 1a is much lighter than the amount of force necessary for actual driving. Thus, the burden on the operator can be greatly reduced.

Then, by the mode setting mechanism 105,
The traveling mode of the cart body 1a can be freely selected according to the use of the operator. For example, the “inter-laboratory movement mode” is for performing complete and rapid inter-laboratory movement, and the “inspection room movement mode” is for moving at very low speed and extremely safely in a narrow range such as moving in an examination room. ,
Each is useful. Further, in the “complete stop mode”, the cart main body 1 a is moved by locking the wheel driving device 15 even if the operator accidentally touches the piezoelectric element 100 or unexpected vibration or collision occurs. Can be taken into consideration, and safety can be improved. The "manual mode" in which manual operation can be performed is useful when it is necessary to manually move a cart or when an operator prefers manual operation.

As described above, according to the eleventh embodiment, it is possible to perform semi-automatic traveling in the form closest to the operator's intention when moving the cart, and to realize safe traveling on top of that. The labor of the operator can be greatly reduced.

Further, as shown in FIGS. 18A and 18B, the cart body 1b has a balance detecting mechanism 111 for detecting the equilibrium state of the cart body 1b, and the unevenness of the ground detected by the balance detecting mechanism 111. An actuator 112 is provided as a balance holding mechanism for keeping the load horizontal according to the slope of the vehicle or the slope.

When moving the cart body 1b of the present embodiment, the operator operates the control switch 107 to give a traveling instruction, and drives the cart body 1b in the intended direction. At this time, the running of the cart body 1b,
The stop, steering in the running direction, adjustment of acceleration and deceleration, and the like can all be instructed by the control switch 107, and the running can be controlled by the control unit 109.

The caterpillar 110 of the cart body 1b travels while absorbing the impact due to steps or irregularities up to a certain level on the floor of the course. Further, as shown in FIGS. 18A and 18B, when the cart body 1b approaches a slope or the like during traveling, the balance detection mechanism 1 is used.
11, the inclination angle of the floor surface is detected in real time, and based on the detection result, the control unit 109 controls the actuator 112 so that the device mounting part of the cart body 1b is always horizontal. When driving the driving device 114 and the actuator 112, the battery 1
06 is connected to a commercial power source for a predetermined time to perform charging.

In this embodiment, by adopting the caterpillar as the traveling means, it is possible to absorb steps, irregularities and the like on the traveling road. Also, by using the balance detection mechanism 111 and the actuator 112, the equipment mounting portion on the cart body 1b can be always kept horizontal, so that even if the cart body 1b
Since the mounted devices and accessories mounted on the vehicle are not affected by the angle of the slope or the like, problems such as dropping and the like are eliminated. Furthermore, due to the nature of a caterpillar, the contact area with the floor surface is larger and the weight is larger than a general cart that uses casters as the traveling means, so that the sense of stability during traveling is improved, such as falling over There are no problems.

As described above, according to the twelfth embodiment, when the cart is moved, the equipment mounting portion can always be kept horizontal even when traveling on a slope without receiving an impact from the floor or the like.
