Abstract

This high-frequency heating treatment apparatus (10) comprises lower and upper electrode devices (100, 200). The lower electrode device (100) comprises an electrode plate (101). The upper surface of the electrode plate (101) is covered with a flexible thin film (102) made of a resin. A pipe (110) is annularly arranged between the electrode plate (101) and the thin film (102). A plurality of holes (110A) are formed in the pipe (110). The upper electrode device (120) is configured similarly to the lower electrode device (100). A biological part (R) is placed between the electrode devices (100, 120), and high frequency power is applied between electrode plates (101, 121), whereby an affected part in the biological part (R) is dielectrically heated. Water introduced in the pipe (110) blows out from the holes (110A) to produce water streams (Q1, Q2). Thus, water (W) between the electrode plate (101) and the thin film (102) is stirred. Accordingly, heat generated on the surface (Ra, Rb) of the biological part (R) is efficiently absorbed by the water (W) through the thin film (102) in contact with the surface (Ra, Rb).

[Operation]
Next, the operation of the high-frequency warming therapy system 11 configured as described above will be described.

First, the treatment bed 20 is moved to the position shown in FIG. 1, and the patient is laid on the treatment bed 20 such that the affected part of the patient (not shown) as a living body is located at the opening 21 of the treatment bed 20. For example, the patient's shoulders are placed on the mat 20B and the patient's waist is placed on the mat 20A such that the chest and abdomen are located at the opening 21.

Next, the operation unit (not shown) of the gantry 30 is operated to move the treatment bed 20 along the guide rails 23 to the position shown in FIG. By this movement, the lower electrode device 100 of the gantry body 32 is located below the opening 21 of the treatment bed 20, and the upper electrode device 120 is located above the opening 21.

Then, the lower electrode device 100 is raised and the upper electrode device 120 is lowered to sandwich a living body part having a diseased part. The patient identification information, the treatment time, the output value of the high frequency power, the first high frequency or the second high frequency used for the treatment, and the like are input in advance by the operation of the operation unit 61.

Next, the start switch (not shown) of the operation unit 61 is turned on. As a result, the high frequency power of the selected first high frequency or second high frequency is output from the high frequency voltage generator 80 and applied between the

electrode plates

101 and 121. As a result, the affected area is dielectrically heated and heating treatment is performed.

On the other hand, when the start switch is turned on, the cooling device 70 shown in FIG. 3 operates and the cooled water is fed to the

water supply pipes

103, 123 by the pumps P1, P2 via the hoses H1a, H2a. The water supplied to the

water supply pipes

103 and 123 is introduced into the

pipes

110 and 130 and is further jetted out from the

holes

110A and 130A of the

pipes

110 and 130 as shown in FIGS. 4 to 7. By this spouting, the water W in the

cooling pads

102, 122 is stirred, and the generated heat of the surface of the living body part in contact with the

cooling pads

102, 122 is efficiently absorbed.

By the way, as shown in FIG. 8, the cooling pad 102 presses the living body portion R, whereby the

recesses

102A and 102B are formed along both sides of the cooling pad 102 along the shape of the living body portion R, for example. Even in such a case, the water W in the cooling pad 102 is agitated by the jet of water upward from the plurality of holes 110A of the pipe 110, so that the arrows Q1 and Q1 in the

concave portions

102A and 102B. As indicated by Q2, water flow does not occur, and water does not stagnate in the

recesses

102A and 102B. Therefore, the generated heat of the surfaces Ra and Rb of the living body portion R in contact with the recessed

portions

102A and 102B can be efficiently absorbed.

Similarly, as shown in FIG. 8A, even if the recessed

portions

122A and 122B are formed on both sides in the cooling pad 122 by the living body portion R, the inside of the cooling pad 122 is jetted downward by the water from the plurality of holes 130A of the pipe 130. When the water W is stirred, water flows in the

concave portions

122A and 122B as shown by arrows Q3 and Q4, and water does not stagnate in the

concave portions

122A and 122B. Therefore, the generated heat of the surfaces Rc and Rd of the living body portion R in contact with the

concave portions

122A and 122B can be efficiently absorbed.

Incidentally, as shown in FIG. 8, the diameter (= r) of the electrode plate is small in the related art, and in the case of this small electrode plate, the depths of the recesses 102A 'and 102B' formed on both sides in the cooling pad 102 'are It is shallow, so that the stagnation of water does not occur so much in the recesses 102A 'and 102B'. For this reason, the problem that the water in the recessed portions 102A 'and 102B' becomes high temperature does not occur. However, when the diameter of the electrode plate 101 is increased, deep

concave portions

102A and 102B are formed on both sides in the cooling pad 102, and the water in the

concave portions

102A and 102B is stagnant to become high temperature. However, according to this embodiment, such a problem will be solved. Even if the

deep recesses

122A and 122B are formed in the cooling pad 122, the same problem does not occur.

Here, in the case where the pipe 110 is made of soft resin and is a so-called rubber hose etc., if it is arranged, for example, on a chain line in FIG. 5 at the time of assembly, water is first introduced into the pipe 110 The water pressure causes the pipe 110 to spread in the planar direction and move to the position shown by the solid line. Thereafter, water can be ejected from the hole 110A of the pipe 110 which has moved to this position each time treatment is performed. When the pipe 110 is a hard resin, it is disposed at the position indicated by the solid line.
Second Embodiment
9 and 10 show the configuration of the lower electrode device 200 of the second embodiment. The lower electrode device 200 is provided with a pipe 210 having an elastic force instead of the pipe 110.

The pipe 210 has an axial pipe portion 211 connected to the inlet 103A of the water supply pipe 103, and a pivoting pipe portion 212 located along the surface of the lower electrode plate 101 from the upper portion of the axial pipe portion 211. There is. The axial pipe portion 211 is orthogonal to the surface of the lower electrode plate 101, and the pivoting pipe portion 212 forms a plurality of holes 212A. The orientation of each hole 212A is set at an angle of approximately 45 ° upward with respect to the horizontal direction, as shown in FIG.

Since the upper electrode device 220 (not shown) is similarly configured, only the lower electrode device 200 will be described below.

When water is spouted from the plurality of holes 212A of the rotation pipe portion 212, the rotation pipe portion 212 spouts water from the holes 212A because the holes 212A face obliquely upward 45 ° with respect to the horizontal direction. As the force rotates clockwise as shown in FIG. 10, the water spouted from the hole 212A is directed to the back surface of the cooling pad 102, so the heat generated on the surface of the living body portion coming in contact with the cooling pad 102 Are absorbed efficiently.

When the pivoting pipe portion 212 pivots to the dashed line position, the water spouting is stopped. Thus, the pivoting pipe portion 212 returns to its original position by the elastic force. Again, water is spouted from the plurality of holes 212A of the turning pipe portion 212. That is, by intermittently ejecting water, the pivoting pipe portion 212 reciprocates between the position of the solid line and the position of the dashed line. By the reciprocation, the water W in the cooling pad 102 is efficiently stirred, and as shown in FIG. 8, even if the

recess

102A, 102B is formed in the cooling pad 102, the water is in the

recess

102A, 102B. The heat generated on the surfaces Ra and Rb of the living body portion R can be efficiently absorbed without stagnation.

When the change in the water pressure of the water jetted from the hole 212A of the turning pipe portion 212 is increased, a larger injection output can be obtained, and the turning pipe portion 212 can be easily deformed.
Third Embodiment

The water spouts directly upward from the plurality of holes 310A, and the spouted water stirs the water W in the cooling pad 102, and the spouted water directly strikes the back surface of the cooling pad 102. Therefore, the heat generated on the surface of the living body portion in contact with the back surface of the cooling pad 102 is efficiently absorbed. Moreover, since the water W in the cooling pad 102 is agitated by the jet of water in the plurality of holes 310A, as shown in FIG. 8, even if the

recesses

102A and 102B are formed in the cooling pad 102. Thus, the generated heat of the surfaces Ra and Rb of the living body portion R can be efficiently absorbed without water stagnating in the

concave portions

102A and 102B.

The upper electrode device 320 (not shown) has a similar configuration, and the same effect can be obtained.

When water is spouted obliquely upward in four directions from the spouts 402A to 402D of the diffusion member 401, the spouted water W in the cooling pad 102 is agitated by this spout, and the spouted water is cooled Since the back surface of the pad 102 is in direct contact with the back surface of the cooling pad 102, the heat generated on the surface of the living body portion in contact with the back surface is efficiently absorbed.

Further, since the water W in the cooling pad 102 is agitated by the ejection of water from the ejection ports 402A to 402D, as shown in FIG. 8, the recessed

portions

102A and 102B are formed in the cooling pad 102. However, water does not stagnate in the

concave portions

102A and 102B, and the generated heat of the surfaces Ra and Rb of the living body portion R can be efficiently absorbed.

When water is supplied to the water supply pipe 103, it is introduced into the rotary pipes 603 to 606 through the axial pipe 601 and the cap member 602, and the water is spouted from the holes 603A to 606A of the rotary pipes 603 to 606. The jets rotate the rotary pipes 603 to 606 together with the cap member 602 clockwise in FIG. The water W in the cooling pad 102 is largely stirred by the ejection of water from the holes 603A to 606A of the rotary pipes 603 to 606 and the rotation of the rotary pipes 603 to 606.

The generated heat of the surface of the living body portion in contact with the back surface of the cooling pad 102 is efficiently absorbed by the stirring.

Further, as shown in FIG. 8, even if the recessed

portions

102A and 102B are formed on both sides in the cooling pad 102, the rotating pipes 603 to 606 are rotated, so that the rotating pipes are rotated in the recessed

portions

102A and 102B. The water spouted from each of the holes 603A to 606A of 603 to 606 surely enters. Therefore, a water flow is generated in the

concave portions

102A and 102B, and the heat generated on the surfaces Ra and Rb of the living body portion R in contact with the

concave portions

102A and 102B can be absorbed.

Furthermore, since the water W in the cooling pad 102 is greatly stirred by the rotation of the rotary pipes 603 to 606, the water flow can be reliably generated in the

concave portions

102A and 102B, and the surface of the living body portion R The generated heat of Ra and Rb can be absorbed more reliably.

The upper electrode device 620 (not shown) has a similar configuration, and similar effects can be obtained.

In this embodiment, the four rotary pipes 603 to 606 are provided, but the present invention is not limited to this, and other plural ones may be provided.
Seventh Embodiment
FIG. 22 shows the lower electrode device 610 of the seventh embodiment. The lower electrode device 610 has pipes 613 to 616 similar to those of the sixth embodiment, and the pipes 613 to 616 are designed not to rotate. A plurality of holes 613A to 616A are formed in the pipes 613 to 616 as in the sixth embodiment.

Further, the

pipes

613 and 615 in the width direction of the living body portion R are set longer than the

pipes

614 and 616. This is because the recessed

portions

102A and 102B (see FIG. 8) are formed on both sides in the cooling pad 102 in the width direction of the living body portion R, so that water flows in the recessed

portions

102A and 102B. In addition, since the recess is not formed in the cooling pad 102 in the upper and lower portions in the vertical direction (in FIG. 22), the

pipes

614 and 616 may be short.

In the lower electrode device 610 of the seventh embodiment, when water is ejected from the holes 613A to 616A of the pipes 613 to 616 in the direction indicated by the arrows, a counterclockwise vortex is formed in the cooling pad 102, and cooling is performed. Heat generated from the surface of the living body portion R in contact with the pad 102 is absorbed more efficiently than efficiency.
Eighth Embodiment
FIG. 23 shows a lower electrode device 700 of the eighth embodiment. In this lower electrode device 700, a heat exchange film 701 is provided in the cooling pad 102, a cooling chamber 702 is formed by the heat exchange film 701 and the lower electrode plate 101, and a heat absorbing chamber is formed by the heat exchange film 701 and the cooling pad 102. In the cooling chamber 702, a cooling liquid G such as an antifreeze liquid is sealed, and in the heat absorption chamber 703, the water W is sealed.

The coolant G is cooled by the cooling device 70 shown in FIG. 3 and is supplied to the cooling chamber 702 in the cooling pad 102. In addition, the coolant G in the cooling chamber 702 is discharged to the cooling device 70.

According to the seventh embodiment, since the coolant G can be set to a low temperature, the entire water W in the heat absorption chamber 703 can be efficiently absorbed through the heat exchange film 701. For this reason, as shown in FIG. 8, even if the

recesses

102A and 102B are formed on both sides in the cooling pad 102, the temperature of the water W of the

recesses

102A and 102B can be lowered. The generated heat of the surface Rb of the living body part R in contact can be absorbed efficiently.

The upper electrode device 720 (not shown) has a similar configuration, and similar effects can be obtained.
[Other example]

Although the space which encloses the water W by each is formed, you may form the space which encloses the water W only with cooling pad 102,122. In this case, it may not be attached to each

electrode plate

101, 121.

In the first and third to sixth embodiments, water is continuously fed into the

cooling pads

102 and 122 during the treatment, but the feeding may be interrupted as in the second embodiment. By doing this, the water W in the

cooling pads

102 and 122 can be efficiently stirred.

Further, in the above embodiment, although the lower electrode devices 100 to 700 and the upper electrode devices 120 to 720 have the same configuration, they need not necessarily have the same configuration. For example, the upper electrode with respect to the lower electrode device 100 Any of the devices 220-720 may be employed.
