Description

Detailed Description of the Invention ((a) Industrial Application Field The present invention is provided with a table that is placed on a base and on which a patient is placed, and that the table can be moved vertically and vertically by remote control. This relates to the improvement of a table-operated operating table that is configured to be able to move and roll over at will using electric power or the like.0 (B) Prior Art This type of operating table has a floor-operated operating table, as shown in FIG. It has a base 1 which is vertically disposed on one surface, and a retaining part 2 for removably mounting a table on the base 1.

The head portion IH of the base 1 is movable in the vertical direction H by a driving means provided inside the base 1, and the engaging portion 2 is held in this vertically movable head portion IH. This engaging portion 2 is held against the head portion IHt so that it can perform a vertical rotation motion β and a horizontal rotation slow motion θ relative to the head portion IH.

The driving means for the vertical movement (H%), the vertical movement (β), and the horizontal movement (θ) will be described later, but the driving source for these is an electric motor, and the electric power therefor is supplied from the power source 8 via the lead wire γ. The on/off operation of each electric motor is performed by a switch provided in a remote control operation switch box 6. 5 is a lead wire.

As shown in FIG. 2, the tape/I/4 is engaged with the retaining portion 2t which is electrically constructed and moves as described above. That is, an engagement tube (not shown) protruding below the table 4 is inserted into the hole 2H of the engagement portion 2 and engaged. The tape /L/4 is moved up and down by the vertical movement H1 of the engaging portion 2, and the table 4 is rotated vertically by the vertical rotation movement β, and horizontally by the horizontal rotation movement θ.

In this way, the table 4 is in various states (postures...
...It is constructed so that the patient's strength and body position can be obtained, and the surgery can be performed in each condition.

However, as mentioned above, when operating the operating table according to the surgical requirements, even if remote control is possible, it is necessary to press each switch on the operation switch box and operate while observing the movement of the tape ρ. Become. Therefore, when operating on a table (when a patient is placed on the table and the table cannot be seen, or when operating from a position too close to the operating table), it is difficult to perform the desired operation.

Although it has been proposed to display the operating angle on the top surface of the operation switch box, it is difficult to recognize the overall status of the operating table just by displaying the angle. Additionally, when operating the switches in an operation switch box, there is a drawback that if there are a large number of switches, operation errors are likely to occur.

(/P) Purpose The present invention aims to solve these conventional problems and provide a table-operated operating table that allows the table to be operated as desired.

B) Construction The table-operated operating table of the present invention is characterized by the fact that the table of the operating table can be operated using a smaller operating table model that has substantially the same shape as the operating table.

In other words, an output means is provided for electrically outputting the motion amounts of the table's -1 downward motion, vertical rotation motion, and sideways motion. A model motion output means is provided for electrically outputting the amount of motion of the table in the model, such as vertical motion, vertical rotation motion, and horizontal motion. The structure is such that each of the seven drive means is controlled so that the output values match.

It is operationally advantageous to provide the model motion output means within the operating table model, and the structure of the entire operating table can be made simple and compact.

(In the illustrated embodiment, the operating table model is installed on the operation switch box to improve operability and simplify the configuration. In addition, the operation table model is installed on the operation switch box to improve operability and simplify the configuration. A switch is shown to enable the table to bend at an intermediate position in the longitudinal direction, but only the drive mechanisms for vertical, vertical, and horizontal movement of the table are shown. .

The relationship between these drive mechanisms and output means for outputting the amount of operation in each drive mechanism will be explained with reference to FIGS. 3 to 5.

FIG. 3 is a schematic diagram (not shown) of the drive mechanism for vertical movement, and the solid line indicates the drive mechanism, which is mounted on the base 1.

Reference numeral 9 denotes a base frame of the drive mechanism, which is fixed on the base 1 side, an integral cylinder portion 9Y is formed on the upper right side, and a guide frame 10 is vertically provided on the left side. The axes of the guide frame 100 guide groove 10M and the V cylinder 9Y are both aligned with the above-mentioned vertical movement direction. .

Reference numeral 11 denotes an electric motor mounted on the base frame 9, and its rotational output rotates a worm 13 via a shaft 12, thereby rotating a worm gear 14 meshing with the worm 13. The rotation of the worm lI actuator 14 is transmitted via the transmission shaft 15 and the gears 16 and 17 to the threaded rod 18 extending through the cylinder portion 9Y, causing the threaded rod 18 to rotate.

The threaded portion 1B' of the threaded rod 18 is the nut 1 attached below the reciprocating body 20 inserted into the cylinder portion 9Y.
9 are screwed together, and therefore, the rotation of this threaded rod 18 causes the reciprocating body 20 to be vertically displaced. The upper end portion of this reciprocating body 20 is fixed to the head portion IH of the base 1, and the head portion IH moves up and down with respect to the main body portion of the base 10. A roller 21 attached to the tip of the arm portion 2OR of the reciprocating body 20 engages with the groove 10M of the guide frame IO, thereby stopping the rotation of the reciprocating body 20 and guiding the reciprocating motion.

The vertical movement of the head part IH causes the retaining part 2 held by it to move up and down, and this vertical movement amount is used as a rotation speed transmitter! is detected and output by That is, 22 is a pinion gear that meshes with the gear 16, and manually inputs the rotation of the gear 16 to a rotation speed transmitter. The rotation speed transmitter 1 outputs a pulsed electric signal proportional to the input rotation speed. In other words, a pulsed electrical signal is output in proportion to the amount of vertical movement of the head portion IH.

Next, the tape/I/4 is rotated vertically, that is, the tape/L/4
A driving mechanism for vertically moving the longitudinal direction of the engaging portion 2 (in the direction of the arrow β) will be described with reference to FIG. In the figure, 23 is an electric motor whose output is transmitted to a rotating shaft 25 via a clutch and a reducer 24, and a bevel gear 26.
, 2'7 to the drive shaft 2 through the transmission system.

The rotation of the transmission shaft 2 is transmitted to the worm 31 via the gear system 29, 30, and the engagement part 2 with which this worm 31 meshes is transmitted.
The power is transmitted to the worm gear 2G.

This worm gear 2G is rotatably housed in the engagement portion chi 72K, and rotates the shaft 2s, thereby rotating the frame body having the retaining hole 2H in the β direction. In this way, the retaining part 2 rotates vertically due to the 230 rotations of the electric motor, and the tape/I
/4 is rotated vertically.

At the same time, the 1'WL motor 230 rotation output is gear system 33.3
The rotation speed transmitter 2 is inputted to the rotation speed transmitter 2 via 4, and outputs a bar/L'-shaped electrical signal proportional to the amount of vertical rotation of the engaging portion 2.

The rolling motion of the engaging portion 2 is performed by a drive mechanism shown in FIG. That is, as shown in Figure 4,
A rotating support shaft 2R protrudes from the engaging portion chi 72K, and this support shaft 2R is rotatably supported by the fixed frame 1) 1/ of the head portion. One end of a rotating lever 35 is attached to this support shaft 2R, and this lever 35
By moving the other end up and down by the electric motor 38,
The support shaft 2R is rotated. The rotational output of the electric motor 391 rotates the screw n42 through a worm gear transmission system consisting of a worm 40 fixed to its output shaft 391 and a worm gear 41. screw! 42t This pin 36 is attached to the other end 35/ of the lever 35.
A nut 37 held through the screw is screwed together, so that each rotation of the screw $1!42 moves the nut 37 up and down and rotates the lever 35.

In this manner, the rotation of the electric motor 38 causes the lever 35 to rotate and the support shaft 2R to rotate, and the rotation of the support shaft 2H causes the engaging portion 2 to perform a rollover motion θ, thereby imparting a rollover motion to the cheagle 4.

At the same time, the gear 43 is meshed with the gear 41, and the engaging portion 2
The amount of rollover operation (the amount of rotation proportional to this is the amount of rotation speed transmitter Ks)
f is input, and a pulse-like electric signal corresponding to this amount of rotation is output.

As described above, the vertical movement of the table 4 m! Each of the IIIJ machine vertical rotation operation drive mechanism and horizontal rotation operation drive mechanism is provided with an output means for electrically outputting the amount of operation thereof. The outputs 1 to 5 to each of these output means are the 7th output.
As shown in Figure t, it is input to the control circuit SB in the base l and counted by a counter (not shown).

The control circuit SB also has the function of controlling the drive of each electric motor using signals from the operation switch box 6, as will be described later. As shown in FIG. 6, indicators D1 to D4 for digitally displaying the operating amount of the tape/I/4 operating switches S1 to S4 and SI' to S4'1 are arranged in parallel. That is, the switches S, , 81' switch the tape/
With the rollover operation amount switch of I/4, press switch S1, the tape/L/4 will roll over with the left side raised, and switch S1 will be pressed.
When you press the button, Table 4 will roll over with its right side raised.

Thereafter, the operations shown on the upper surfaces of the switches S1 to S4 and S to S4' are performed in the same manner. This means that the operation signals from each switch in A are as shown in Figure 7.
This is because the signal is inputted to the control circuit SRt and controls the forward and reverse rotation of each electric industrial machine. 1. Is the amount of movement of each drive mechanism transmitted? The electric signal F is converted from rK1 to rK5 and input to the counter OB, and its output is transmitted to each display D1 to D4 of the operation switch box 6 via the lead m5 and displayed.

The display Dot shows the roll motion angle θ, the display D2 shows the vertical roll motion angle β, the display D5 shows the bending (buckling) motion angle d of the cheagle, and the display D4 shows the table vertical motion. The quantity (6M) is displayed digitally. The structure of the digital displays D1 to D4 includes various types of display units such as mJjl, and their WP#l is omitted. As is clear from FIG. 6, the operation switch box 6t is also juxtaposed with an on/off switch made by Tape IfJh.

Although the configuration and operation of the operation switch are roughly as described above, the feature of the present invention is not in the configuration of the operation switch box 6, but rather in the operation table tape/I without depending on the switch group of the operation switch box 6. There is one point where you can manipulate /4.

That is, as is clear from FIG. 6 showing the operation switch box 6, this kind of switch box 6 is equipped with an operating table model MD which is approximately the same shape as the operating table and is miniaturized. Identical does not include anything that is exactly the same as an operating table, but it also includes a shape that is within the range of the configuration of the tape ρ, which is the main part of the operating table, that is, the vertical movement mechanism, vertical rotation mechanism, and horizontal rotation mechanism of the table. means.

The above-mentioned vertical movement, vertical roll F1, and horizontal roll movement of the operating table model MD are performed manually (with fingertips) by the operator (doctor, nurse, etc.)
The operation was performed on the operating table ν! Type MD is so constructed. Furthermore, a model motion output means Kw'sK2'sK5' is passed to this frame MD, which outputs the motion amount of each of these motions as an electric signal. In the output means, ' corresponds to 1 in the 1,000 □ stage of the operating table, and similarly K 2' is 2 t, and ni.
/ corresponds to KS. It is preferable that the output signal from - to 5' to the output means be a binary code signal that can be compared with other digital signals.
is an engoder, requires a decoder, and is outputted via the decoder.

The operating table of the present invention can freely operate the tape/I/4 of the operating table as desired by means of the operating table model MD.A schematic of this operation control system is shown in FIG.

The basic feature of this operation control is that each drive mechanism of the operating table is controlled so that the output value from the output means of the operating table matches the output value from the output means of the operating table model.

There are three output means, so each corresponds to ff.
The surface output values are compared. In the control system shown in FIG. 8, only the configuration for the overturning operation of the table 4 on the operating table is representatively shown.

Therefore, a control system similar to that shown in FIG. 8 is provided for both the vertical movement and the vertical rotation movement. These are the control box OB at the base of the operating table as shown in Figure 7.
It's hard to be fucked inside. Of course, three of the systems shown in FIG. 8 may be arranged in parallel as they are, but parts that can be used for the same purpose can be used for the same purpose, and parts that can be combined as the same part in terms of control function can also be combined as the same member. A part of the control system having such a configuration is shown in FIG. Four structures are shown, and on the left side is shown the rollover motion output means K s / in the operating table frame type MDt.

In the control box (3B), 44 is a memory circuit which has the function of storing the signal input by the command signal from the operation switch box 6.4
5 is a command signal t from switch D of switch box 6 which is operated in the same manner. When the relay is operated, the selector switch 46 is switched from the illustrated terminal T1 to T2.

47 is a comparison circuit which receives the output value (digital signal) outputted from 3 to the output means via the decoder 49;
When the changeover switch 46 is in the normal state shown, the output value from the decoder 49 is written f,! to circuit 44. Therefore, when the storage circuit 44 receives the command signal from the switch M, it stores the output value from the comparison circuit 47 (the output value from the decoder 49) at that time. Although this storage function is not directly related to the features of the present invention, when a certain state is stored and desired to be reproduced, the table state of the stored state is reproduced by a command signal from the reproduction switch R.

In this reproduction state, the comparator circuit compares the stored value of the memory circuit 44 and the output value of the decoder 49, and provides the difference signal (large/small signal) O8 to the selection circuit 5. The selection circuit 5o selects the Mg driving source 38.39.40 due to the difference signal t.
．． 41. Selects in which direction 43 should be operated and instructs the drive control circuit SB to operate. 0 Through this operation, the output value from 5 approaches the stored value in the output means, and when the two match, a match signal ES is sent. is output and input to the flip-flip circuit 48.

The flip-flop circuit 48 operates in response to a command signal from the switch R, and provides an operation stop signal to the selection circuit 5o in response to the input of the coincidence signal ES.

Then, the operation of the drive control circuit SB is stopped, the rollover operation is stopped, and the memorized state is reproduced. The state of the table 4 to be stored may be manipulated by operating a group of switches on the operation switch box 6, or by operating the operating table model MD, which will be described next.

When operating the table 4 using the operating table model MD, which is a feature of the present invention, the switch D on the operation switch box 6 is pressed to operate the relay 45 and switch the changeover switch 46 to the terminal T2 side.

The output from 3' is connected to the terminal T2 through the decoder 51 to the model motion output means, that is, the output means corresponding to the rollover motion. The output value from the operating table model MD will be compared with the output value from the operating table model MD.

This comparison operation is performed when one of the command signals from switch D is also input to the Fligfrodde circuit 4.

That is, the comparison result by the comparison circuit 47,
The difference signal OS is inputted to the selection circuit 5o in the same manner as in the reproduction operation of the memory state. And the same as above, this drive source 3
8 to 41. The operating direction of 43 is selected and the drive control circuit S
An instruction is given to the operating table model MD, and the drive mechanism operates so that the output value from the decoder 49 approaches the output value t from the operating table model MD.

In this way, the tape /l/4 on the operating table is operated along with the movement of the model MD. Vertical rotation and vertical movements are also operated in the same way.

The present invention is not limited to the illustrated example, but includes various modified embodiments. In the illustrated example, an electric motor is used as a means for driving the table, but a hydraulic drive method may also be used. Also, the means for electrically outputting the amount of operation by each of these driving means is not limited to the encoder. Although it is desirable to output the signal as a digital signal, it is also possible to output the signal as an analog signal. In addition to the encoder, something like Magnescale may also be used.

The size of the operating table model is not limited to the illustrated example, and may be smaller or slightly larger. Also, it is not an essential condition that it be installed on the operation switch box. Furthermore, the model motion output means in the operating table model is as follows:
By installing the model, the overall size can be reduced and operability can be improved, but it is not limited to being installed on the model.

Furthermore, the control means for controlling each drive means to make the output value from the output means of the operating table match the output value from the model motion output means of the operating table model is not limited to that shown in FIG. do not have. Even in the case of the circuit configuration as shown in FIG. 8, the memory function can be omitted. The illustrated example of the configuration of the operation switch box is only one example. In particular, a display that digitally displays the tilt angle of the table is also not an essential requirement. The format, type, and configuration of the operating table is not limited to the illustrated example, and various types can be used. For example, the present invention can be applied to a double-layer treatment table (treatment chair) and an X@medical treatment table.

(f) Effects The present invention provides an operating table with excellent operability in terms of table movement.

In other words, it is best to operate the table while observing the condition of the table, but in reality, when a patient is on board for surgery, it is difficult to accurately grasp the condition of the table, so operations that require frequent observation of the table are unnecessary. Although possible, according to the invention the operating table 8! Since operation using molds becomes possible, a surgical table with good operability can be obtained.
