That is, when a column for a general operating table is used as a column for an ophthalmic operating table, the height of the column from the floor surface becomes high. Therefore, it is difficult to perform the operation, and as a result, the column used for the separate operating table must use a column dedicated to ophthalmology, at least, a column for general surgery and a column for ophthalmology. There was a problem that two columns were required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide a general operating table and an ophthalmic operating table with different identification codes, and use an identification code from the operating table. It is an object of the present invention to provide an operating table apparatus which can determine which operating table has been set on the column side and perform control unique to each operating table.

[0006]

SUMMARY OF THE INVENTION An operating table apparatus according to the present invention achieves the above-mentioned object, and includes a control circuit for performing a motion peculiar to an operating table, and an operating table provided by the operating table. The control circuit is provided with an identification code for identifying the type of operating table for use or for general use, and the column that enables control of the various operating tables during surgery is read by the identification code. The column is driven such that only a specific movement of the operating table is possible.

When a power supply for controlling the operating table alone is connected to a power supply for controlling the column alone, control of the operating table and control of the column can be performed using only one of the power supplies. Is performed so as to perform the above operation.

Can be controlled so that the vertical and horizontal angles can be adjusted as shown in the figure, or the entire operation table A can be moved up and down. That is, it has a function that can also be used as a column dedicated to ophthalmology and a column for an operating table for general surgery and the like, and is fixed in an operating room.

A control circuit 8 for controlling the operating table A so that the vertical and horizontal angles can be adjusted or for raising and lowering the entire operating table A is attached to the control circuit 8. A hand switch or a foot switch (not shown) is connected. Although the control circuit 8 is shown attached to the side surface of the column C in the drawing, it may be located at any position within the column C.

Next, details of the pillow device D attached to the front side of the ophthalmic operating table A will be described with reference to FIGS. 6 to 8, reference numeral 9 denotes a motor fixed to the front lower surface of the operating table A, and a screw rod 10 is attached to an output shaft 9 a of the motor 9. 11 is the screw rod 1
The nut holder 11 is a nut holder to which a nut 11 a screwed to the front end side of the nut 0 is fixed. The nut holder 11 is supported by a pair of support plates 12.

Reference numeral 13 denotes a parallel link whose one end is pivotally supported by the support plate 12, and 14 denotes a parallel link whose bent portion 14a is pivotally supported by the support plate 12. The base end is the nut. It is pivotally supported by the holder 11a. Reference numeral 15 denotes a pillow main body, and the other ends of the parallel links 13 and 14 are pivotally supported on a substrate 15a of the pillow main body 15.

With this configuration, the motor 9
When the screw rod 10 is rotated by rotating the nut, the nut holder 11 moves in the left-right direction in FIGS. 6 to 8, so that the parallel links 13 and 14 are displaced and the pillow as shown in FIG. 7 or FIG. The main body 15 is moved up and down in the vertical direction.

In FIGS. 9 and 10, reference numeral 16 denotes a pitching knob rotatably mounted between the substrates 15a of the pillow body 15, and a spiral gear 16a is fixed to an intermediate portion. A pitching screw 17 is meshed with the spiral gear 16a, and a pitching screw to which a spiral gear 17a rotating with the rotation of the spiral gear 16a is attached. A nut 18a to which the pitching screw 17 is screwed is fixed. A nut holder is rotatably supported on the substrate 15a of the pillow body 15. 19
The shaft 17b in which the thread of the pitching screw 17 is not formed is free in the rotation direction, but is a bearing that is pivotally supported so as to be restrained in the axial direction. It is rotatably supported.

With this configuration, when the pitching knob 16 is rotated, the spiral gear 17a is rotated via the spiral gear 16a, so that the pitching screw 17 is rotated. Thereby, since the pitching screw 17 is screwed with the nut 18a,
The pitching screw 17 moves in the left-right direction in FIGS.

At this time, the shaft 17 of the pitching screw 17
Since b is rotatable by the bearing portion 19 but is restricted in the axial direction, the bearing portion 19 rotates the board 15a of the pillow body 15, and accordingly, the pillow body 15 is connected to the parallel link 13 and the board 15a. Will be rotated with the shaft fulcrum as a fulcrum. That is, the head is moved up and down with the patient's neck as a fulcrum.

11 and 12, reference numeral 20 denotes a shaft fixed to the lower surface of the board 15a of the pillow body 15, and a lock metal 21 is rotatably supported by the shaft. The portion of the lock metal 21 corresponding to the shaft 20 is a slot 2
1a is formed, the lock metal 21 is rotatable with respect to the shaft rod 20 in a state where the interval between the slits 21a is widened, and the lock metal 21 is
Fixed against.

A rectangular guide hole 21b is formed in the lock metal 21, and a prismatic guide in which a wrist rest 22 for supporting a wrist when a doctor performs an operation is mounted in the guide hole 21b. The shaft 22a is slidably mounted. The wrist rest 22 includes an upright shaft 22b fixed to the guide shaft 22a, and a vertically movable rod 22d attached to the upright shaft 22b by a screw 22c so as to be vertically movable.

Further, the lock metal 21 has a shaft 21.
c, a screw 21e for fixing the guide shaft 22a,
e and a nut 21f screwed to the lock lever 21d and fixed to the lock lever 21d.

With this configuration, the screw 21
When e is loosened, the guide shaft 22a inserted into the guide hole 21b becomes free, so that the wrist rest 22 can be shifted in the front-rear direction with respect to the pillow body 15. In this state, the slot 2 of the lock metal 21
Since the interval of 1a is wide, it is possible to rotate the lock metal 21 with respect to the shaft 20.
The wrist rest 22 can also be rotated.

In this state, when the screw 21e is tightened, the tip of the screw 22e comes into contact with the side surface of the guide shaft 22a, so that the movement of the guide shaft 22a is prevented. In addition, the nut 21f is retracted by the reaction of the screw 22e when the screw 22e is tightened, so that the nut 21f rotates counterclockwise in FIG. 11 around the lock lever 21d or the shaft 21c to which the nut 21f is fixed. At this time, since the tip of the lock lever 21d rotates in a direction to narrow the gap between the slits 21a, the gap between the slits 21a is narrowed, and the metal lock 21 is fixed to the shaft 20.
Therefore, the rotation of the wrist rest 22 is also prevented.

Next, the overall operation will be described based on the above-described configuration. First, the operation table A is set on the stretcher B, and is placed on the drip, anesthesia, disinfection and pillow device D in order to shorten the operation time in the anterior room and in preparation while the power supply is connected to the connector 3. By operating the operation surface 4a of the patient's head, the patient's head is set in a state suitable for surgery.

That is, the pillow body 15 is driven by driving the motor 9.
Is moved vertically to move the patient's head up and down, and the pitching knob 16 is rotated to rotate the pillow body 15 to rotate the patient's head around the neck as a fulcrum. Set the head at the desired angle. Screw 2 in operating room
By loosening 1e, the wrist rest 22 is moved in the front-rear direction, and the wrist rest 22 is turned in the left-right direction to be set at a position desired by the operator.

After the preparation is completed, the operating table A is removed from the stretcher B and set on the column C. At this time, the control circuit 4 set in the operating table A transmits an identification code indicating that the operating table is an ophthalmic operating table A to the control circuit 8 set in the column C. Recognizing that the operating table A is for operation, for example, the operation is performed so that the maximum operation angle of the vertical rotation operation shown in FIG. An operation to prohibit the rollover operation is performed.

Incidentally, a general operating table may have an identification code different from that of the ophthalmic operating table A, or only the ophthalmic operating table A may have an identification code as described above. Only when the identification code is read, it may be determined that the operating table A is an ophthalmic operating table.

Although a power source is connected to the column C in advance, a power source is also connected to the operating table A. Therefore, when the operating table A is set on the column C, the power source of the column C itself is not connected. The power supply of the operating table A is connected.

When the two power supplies are connected to the column C, the power supply of the operating table A and the power supply of the column C collide with each other, causing a problem. Therefore, in the present invention, FIG.
The circuit shown in FIG. That is, the relay R is connected to the power supply unit on the operating table A side, and when the power supply unit is connected to the power supply, the relay R operates and the contact r is switched to the state shown in FIG. The control circuit 4 and the motor 9 of the operating table A are operated by the power supply. Of course, the motor and the like built in the column C are also driven by the power supply on the column side.

[0030]

As described above, the present invention provides a control circuit for performing a motion peculiar to an operating table, and an identification code for identifying the type of operating table, such as an ophthalmic or general operating table. In the control circuit, read the identification code in a column that enables control of the various operating tables at the time of surgery, and drives the column so that only a unique movement of each operating table is possible. As a result, each operating table performs only a specific movement due to the column, and thus a medical error due to an incorrect operation during the operation can be prevented.

When a power supply for independently controlling the operating table is connected to a power supply for independently controlling the column, control of the operating table and control of the column are performed using only one of the power supplies. Since the switching is performed as described above, it is possible to prevent the control failure due to the collision of the power supplies, and so forth.
