[0048] Hereinafter, embodiments of the treatment apparatus of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to these embodiments. Furthermore, in the accompanying drawings, the same or corresponding elements are appropriately labeled with the same reference numerals. Also, the drawings are schematic, and it should be noted that the dimensional relationships and proportions of the elements may sometimes differ from reality. The drawings may also sometimes include portions with different dimensional relationships or proportions.

[0049] (Implementation Method 1)

[0050] Figure 1 This diagram schematically illustrates the treatment system according to Embodiment 1 of the present invention. Treatment system 1 is a system that uses a pair of gripping plates to hold the part of a biological tissue that is the object of treatment (object part), while simultaneously applying vibration or high-frequency current to the held object part to perform ablation, coagulation, cutting, etc. The treatment system 1 includes a treatment device 2, a vibrator unit 3, a control device 4, and connecting cables 5.

[0051] The treatment device 2 applies heat to the object being held, thereby burning, solidifying, or cutting the object. The structure of the treatment device 2 is described later.

[0052] The transducer unit 3 generates ultrasonic vibrations under the control of the control device 4. The transducer unit 3 includes, for example, an ultrasonic transducer. The ultrasonic transducer has a piezoelectric element, and ultrasonic waves are generated by supplying current to this piezoelectric element. The ultrasonic transducer is directly or indirectly connected to the treatment device 2 (the probe body 201 described later), and propagates the generated ultrasonic waves towards the probe body 201. Furthermore, the transducer unit 3 is electrically connected to the control device 4 via a connecting cable 5.

[0053] The control device 4 supplies power to the oscillator unit 3 and the probe body 201, and controls the drive of the oscillator unit 3. The control device 4 is composed of general-purpose processors such as CPU (Central Processing Unit), FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), and other special-purpose processors that perform specific functions.

[0054] The treatment device 2 includes a probe part 20, a first main body part 21, a second main body part 22, and a shaft member 23.

[0055] The probe part 20 has a probe body 201 and a protective sleeve 202.

[0056] The first main body 21 has a clamping member 210, a gripped part 211, and a cover 212.

[0057] The second main body 22 has a connecting part 220 and a holding part 221.

[0058] Furthermore, in the treatment device 2, the side of the sheath 202 connected to the oscillator unit 3 along its length is designated as the "base end" side, and the opposite side is designated as the "front end" side. In addition, among the three mutually orthogonal directions (X direction, Y direction, and Z direction), the length direction of the sheath 202 of the treatment device 2 is designated as the X direction, and the direction of the central axis of the shaft member 23 is designated as the Z direction.

[0059] The probe body 201 is constructed using a rod. The probe body 201 vibrates longitudinally in a direction parallel to the length direction (in this case, the X direction) of the probe body 201 using ultrasonic waves propagating from the transducer unit 3. The heat and friction generated by this longitudinal vibration are used to burn, solidify, or cut the target area. Furthermore, high-frequency power is supplied to the probe body 201 from the control device 4. When high-frequency power is supplied, a high-frequency current is passed to the target area based on the potential difference generated between the probe body 201 and the clamping member 210, performing burning, solidification, or cutting. When high-frequency power is supplied, the probe body 201 and the clamping member 210 (holding member 210a) become electrodes for the flow of high-frequency current.

[0060] In this embodiment 1, the front end of the probe body 201 corresponds to the first gripping part.

[0061] The sheath 202 is inserted through the probe body 201 and surrounds the probe body 201.

[0062] The clamping member 210 is rotatably disposed relative to the probe portion 20. The clamping member 210 passes through the sheath 202 and rotates about an axis orthogonal to the length axis of the sheath 202. Furthermore, the clamping member 210, together with the probe body 201, grips the target portion at one end. Specifically, a gripping member 210a is provided at one end of the clamping member 210. The clamping member 210 holds the gripping member 210a in a freely oscillating position. The gripping member 210a rotates, for example, about an axis extending in a direction orthogonal to the length axis of the sheath 202. Furthermore, the clamping member 210 is connected to the gripped portion 211 at the other end.

[0063] In this embodiment 1, the front end of the clamp member 210 (gripping member 210a) corresponds to the second gripping part.

[0064] The gripping part 211 is the part that is gripped by the surgical operator. A through hole 211a is formed in the gripping part 211 to engage with a part of the surgical operator's hand (e.g., the thumb).

[0065] The cover 212 covers the connection portion where the clamp member 210 is connected to the gripped part 211.

[0066] The connecting portion 220 retains the sheath 202 and is connected to the oscillator unit 3. The connecting portion 220 has a guide portion 220a, which guides the rotational direction of the first main body portion 21 by clamping the gripped portion 211. The guide portion 220a has a concave shape that is opposite to the gripped portion 211 when the gripped portion 211 moves to the side of the second main body portion 22.

[0067] The gripping part 221 is the part that is gripped by the surgical operator. A through hole 221a is formed in the gripping part 221 to engage with other parts of the surgical operator's hand (e.g., index finger, middle finger).

[0068] Operation buttons 22a and 22b are provided on the second main body 22. For example, operation button 22a is used to generate ultrasonic vibrations in the probe body 201. Operation button 22b is used to supply high-frequency power to the probe body 201 to deliver a high-frequency current to the target area. Each button outputs a signal to the control device 4 when pressed by the surgical operator. The control device 4 drives the transducer unit 3 or supplies high-frequency power to the probe body 201 in response to the input signal.

[0069] The shaft member 23 is cylindrical and is disposed through the sleeve 202 and the clamping member 210. Both ends of the shaft member 23 are held in place by the clamping member 210. Therefore, the clamping member 210 can slide relative to the shaft member 23 and rotate freely relative to the sleeve 202. Specifically, the shaft member 23 passes through the clamping member 210 at both ends, holding the clamping member 210 so that it can rotate freely about a central axis. This central axis is the central axis of the shaft member 23, along... Figure 1 It extends in the Z direction and is orthogonal to the length axis of the sheath 202.

[0070] The treatment device 2 can rotate the clamping member 210 relative to the probe body 201 about the axis member 23 (central axis) by operating the gripping parts 211 and 221. At this time, the gripping member 210a moves along the trajectory L as the clamping member 210 rotates, approaching or abutting against the probe body 201. This trajectory L is the path that the clamping member 210 (gripping member 210a) passes through at a predetermined position when the gripping part 211 approaches or moves away from the gripping part 221.

[0071] After the clamping member 210 is rotated and the object is clamped by the probe body 201 and the holding member 210a, and the operation buttons 22a and 22b are pressed, energy generated by ultrasonic waves or high-frequency electricity is supplied to the probe body 201 under the control of the control device 4. By supplying energy to the probe body 201, the object can be burned, solidified, or cut.

[0072] Next, refer to Figure 2 , Figure 3This section describes an example of adjusting the relative positions of the probe body 201 and the clamping member 210 of the treatment device 2, particularly when gripping the object. Figure 2 It means Figure 1 A diagram showing the structure of the main parts of the treatment device. Figure 3 It means Figure 1 A cross-sectional view of the structure of the main parts of the treatment device shown. Figure 3 This is a cross-sectional view showing the structure of the holding part 211 and the connecting part in a cross-section obtained by cutting through the plane of the protrusion 211b, which will be described later.

[0073] For example, in the factory that manufactures disposal device 2, the following position adjustment is performed during the inspection process before the disposal device 2 leaves the factory.

[0074] The gripped portion 211 has a protrusion 211b that slides relative to the guide portion 220a. The protrusion 211b protrudes relative to the main body of the gripped portion 211. The protrusion 211b determines the position of the first main body portion 21 relative to the second main body portion 22 by contacting the inner wall surface of the guide portion 220a when the gripped portion 211 is housed in the guide portion 220a. In this embodiment 1, the protrusion 211b corresponds to an adjustment mechanism.

[0075] The protrusion length of the protrusion 211b is set based on the relative position when the probe body 201 and the clamp member 210 (holding member 210a) are brought close together. By adjusting the protrusion amount of the protrusion 211b, the position of the holding part 211 relative to the connecting part 220 is adjusted in the direction of arrow Q1. Here, the protrusion 211b is provided on the side that is offset relative to the body of the holding part 211, depending on the offset direction of the probe body 201 and the clamp member 210.

[0076] Furthermore, the holding portions 211 and 221 are formed, for example, by molding. Additionally, if the required amount of protrusion can be predicted in advance based on deviations of the part, the protrusion 211b can be provided during molding. In this case, for example, by setting the molding die to a nested structure, it can be configured to be adjustable to any protrusion length.

[0077] Figure 4 and Figure 5 This is a diagram illustrating the adjustment method of Embodiment 1 of the present invention. Figure 4 This diagram shows the state in which the gripping member 210a and the probe body 201 are joined together, and shows the positions of the probe body 201 and the clamping member 210 (gripping member 210a) when the gripped part 211 does not have the protrusion 211b. Figure 5This diagram shows the state in which the gripping member 210a and the probe body 201 are joined together, and shows the positions of the probe body 201 and the clamping member 210 (gripping member 210a) when the gripped part 211 has a protrusion 211b.

[0078] exist Figure 4 In the illustrated state, the position of the holding member 210a is offset relative to the probe body 201. Specifically, the distance d between an outer edge of the probe body 201 and the outer edge of the holding member 210a is... 10 The distance d between the outer edge of the probe body 201 and the outer edge of the holding member 210a is smaller than the distance d between the outer edge of the probe body 201 and the outer edge of the holding member 210a. 20 The holding member 210a is offset from the probe body 201. At this time, the trajectory L passing through the central part of the holding member 210a is offset from the probe body 201. In addition, the central part referred to here is the center of gravity position of the original position of the holding member 210a relative to the probe body 201.

[0079] In contrast, Figure 5 In the shown configuration, the holding member 210a is centrally located relative to the probe body 201. Specifically, the distance d between an outer edge of the probe body 201 and the outer edge of the holding member 210a is... 11 The distance d between the other outer edge of the probe body 201 and the outer edge of the holding member 210a 21 The same applies. The trajectory L of the holding member 210a as it approaches the probe body 201 is adjusted by using the protrusion 211b to adjust the position of the holding part 211 relative to the guide part 220a. When adjusting the trajectory L, the relative positions of the probe body 201 and the holding member 210a when they are close together can also be adjusted. The trajectory L can be clamped into the object area as long as its extension line passes through the probe body 201, but from the viewpoint of ensuring characteristics such as cutting and durability, it is preferable to pass through the center of the probe body 201.

[0080] In Embodiment 1 of the present invention described above, the relative position of the first main body 21 with respect to the second main body 22 is adjusted by providing a protrusion 211b that slides relative to the second main body 22. According to Embodiment 1, by adjusting the protruding length of the protrusion 211b, the positions of the gripping part, the probe body 201, and the clamp member 210 (gripping member 210a), which are the objects to be gripped, facing each other can be adjusted with high precision.

[0081] Alternatively, in Embodiment 1, the structure can be configured such that the protrusion 211b is threaded on one side of the gripped portion 211, allowing the amount of protrusion of the gripped portion 211 from the main body to be adjusted according to the amount of rotation of the protrusion 211b. By making the amount of protrusion of the protrusion 211b adjustable, the surgeon or other personnel can make adjustments on-site.

[0082] In addition, in embodiment 1, a protrusion may be provided on the front end side of the clamp member to abut against the guide portion provided on the sheath 202 and used to guide the rotation trajectory of the clamp member 210, and the position of the probe body 201 and the gripping member 210a may be adjusted by abutting.

[0083] (A variation of Implementation Method 1)

[0084] Next, refer to Figure 6 A variation of Implementation Method 1 is described. Figure 6 This diagram shows the structure of the main parts of the treatment device in a modified embodiment of Embodiment 1 of the present invention. Furthermore, the overall structure of the treatment system in this modified embodiment is the same as that of the treatment system 1 described above, except for a change in the structure of the protrusion; therefore, description is omitted. Hereinafter, structures different from those in Embodiment 1 will be described.

[0085] In the modified example, the protrusion 220b is provided on the guide portion 220a side and abuts against the gripped portion 211. The protrusion 220b protrudes relative to the main body of the connecting portion 220. The position of the first main body portion 21 relative to the second main body portion 22 is determined by the protrusion 220b contacting the outer peripheral surface of the gripped portion 211 when the gripped portion 211 is housed in the guide portion 220a. The protruding length of the protrusion 220b is set in the same way as that of the protrusion 211b.

[0086] In the modified examples described above, the structure of the protrusion was changed compared to Embodiment 1, but since the behavior of the processing device itself remained unchanged, the same effect as Embodiment 1 could be obtained.

[0087] (Implementation Method 2)

[0088] Next, refer to Figures 7-11 Description of Implementation Method 2. Figures 7-10 This diagram shows the structure of the main parts of the treatment device according to Embodiment 2 of the present invention. Furthermore, the overall structure of the treatment system in Embodiment 2 is the same as that of Treatment System 1 described above, except for the adjustment mechanism that changes the relative position of the probe body and the clamp member; therefore, its description is omitted. Hereinafter, a structure different from Embodiment 1 will be described.

[0089] The treatment device of this embodiment 2 replaces the first main body 21 of the treatment device 2 described above and has a first main body 21A. The first main body 21A has a clamping member 210A and a gripped part 211. In addition, the clamping member 210A has a gripping member 210a at its front end, but... Figure 7 The diagram shows the structure with the holding member 210a disassembled.

[0090] The clamping member 210A rotates around the central axis of the shaft member 23, and together with the probe body 201, grips the object part. The clamping member 210A is connected to the gripped part 211 at the other end.

[0091] The clamping member 210A has a protrusion 210b connected to the gripped part 211. The protrusion 210b extends in a direction parallel to the XY plane and can move freely in the Z direction (see reference). Figure 8 and Figure 9 The protrusion 210b is fixed after its position has been adjusted based on the positional relationship between the probe body 201 and the holding member 210a. For example, the protrusion 210b is fixed after adjusting its position from... Figure 9 The initial position shown in (a) is adjusted to Figure 9 The position shown in (b) is then fixed to the adjusted position.

[0092] Here, the gripping part 211 has a connecting part 211c that connects to the clamping member 210A. A hole 211d for receiving the protrusion 210b of the clamping member 210A is formed in the connecting part 211c (see reference). Figure 10 Additionally, the connecting part 211c is covered by the cover 212 during the assembly of the handling device.

[0093] Figure 11 This diagram illustrates the adjustment method according to Embodiment 2 of the present invention. By inserting and fixing the protrusion 210b of the clamping member 210A into the hole 211d, the clamping member 210A is connected to the gripped portion 211. At this time, the clamping member 210A is adjusted relative to the gripped portion 211 in the direction of arrow Q2 according to the position of the protrusion 210b. Through this adjustment, the trajectory L of the gripping member 210a changes, adjusting the relative position of the probe body 201 and the gripping member 210a. In this Embodiment 2, the adjustment mechanism is constituted by the protrusion 210b and the hole 211d.

[0094] In Embodiment 2 described above, the position adjustment structure of the probe body 201 and the holding member 210a is changed compared to Embodiment 1. However, since the behavior of the treatment device itself remains unchanged after the adjustment, the same effect as Embodiment 1 can be obtained.

[0095] (A variation of Implementation Method 2)

[0096] Next, refer to Figure 12and Figure 13 A variation of implementation method 2 is described. Figure 12 This diagram shows the structure of the main parts of the treatment device in a modified embodiment 2 of the present invention. Furthermore, the overall structure of the treatment system in this modified embodiment is the same as that of treatment system 1 described above, except for the adjustment mechanism that changes the relative position of the probe body and the clamp member; therefore, its description is omitted. Hereinafter, a structure different from that of embodiment 1 will be described.

[0097] In this modified example, the treatment device replaces the first main body 21 of the treatment device 2 described above and has a first main body 21B. The first main body 21B has a clamping member 210 and a gripped part 211A. Furthermore, the clamping member 210 has a gripping member 210a at its front end, but... Figure 12 The diagram shows the structure of the holding member 210a after it has been disassembled.

[0098] The gripping portion 211A is the part that is gripped by the surgical operator. A through hole 211a is formed in the gripping portion 211A to engage with a part of the surgical operator's hand (e.g., the thumb). Furthermore, the gripping portion 211A has a connecting portion 211c that connects to the clamp member 210. And, the connecting portion 211c is provided with a rotating shaft portion 211e that connects the clamp member 210 to rotate freely. The rotating shaft portion 211e extends in a direction orthogonal to the length direction of the gripping portion 211A and the central axis of the shaft member 23 (in this case, the Y direction).

[0099] The clamping member 210 is supported on the rotating shaft 211e and connected to the gripped part 211A. The clamping member 210 can rotate freely about the rotating shaft 211e. The rotating shaft 211e causes the clamping member 210 to move on a plane that intersects the direction in which the probe body 201 and the clamping member 210 face each other. Here, the direction in which the probe body 201 and the clamping member 210 face each other is a direction parallel to the XY plane, and the plane intersecting this direction is the XZ plane.

[0100] Figure 13 This diagram illustrates the adjustment method of a modified embodiment 2 of the present invention. The clamping member 210 is rotated about the rotation axis 211e to adjust the positions of the probe body 201 and the gripping member 210a. At this time, the clamping member 210 is adjusted relative to the gripped portion 211A in the direction of arrow Q3. Through this adjustment, the trajectory L of the gripping member 210a changes, thereby adjusting the relative positions of the probe body 201 and the gripping member 210a.

[0101] In the modified example described above, the position adjustment structure of the probe body 201 and the holding member 210a is changed compared to the above-described embodiment 2. However, since the behavior of the treatment device itself remains unchanged after the adjustment, the same effect as embodiment 2 can be obtained.

[0102] (Implementation Method 3)

[0103] Next, refer to Figures 14-16 Description of Implementation Method 3. Figure 14 This diagram shows the structure of the main parts of the treatment device according to Embodiment 3 of the present invention. Furthermore, the overall structure of the treatment system in Embodiment 3 is the same as that of Treatment System 1 described above, except for the adjustment mechanism that changes the relative position of the probe body and the clamp member; therefore, its description is omitted. Hereinafter, a structure different from Embodiment 1 will be described.

[0104] In this embodiment 3, the treatment device replaces the clamping member 210 of the treatment device 2 described above and includes a clamping member 210B. The clamping member 210B rotates about the central axis of the shaft member 23 and, together with the probe body 201, grips the target portion. The clamping member 210B is connected to the gripped portion 211 at its other end.

[0105] The clamping member 210B has spacers 210c and 210d disposed between the clamping member 210B and the shaft member 23. Spacer 210c is disposed at one end of the shaft member 23 in the direction of the central axis. Spacer 210d is disposed at the other end of the shaft member 23 in the direction of the central axis.

[0106] The spacers 210c and 210d are partially open annular (C-shaped) loops formed by bending the strip-shaped members. Alternatively, protrusions may be provided on the inner circumferential side. The spacers 210c and 210d move the clamp member 210B along the central axis of the shaft member 23 by adjusting the length (hereinafter referred to as "width") of the portion corresponding to the central axis direction of the shaft member 23. The position of the clamp member 210B relative to the sheath 202 is adjusted by the arrangement of the spacers 210c and 210d. In this embodiment 3, the spacers 210c and 210d function as an adjustment mechanism.

[0107] Figure 15 and Figure 16 This is a diagram illustrating the adjustment method of Embodiment 3 of the present invention. In the presence of, for example... Figure 15 In the case of spacers 210c and 210d shown, the probe body 201 and the holding member 210a become Figure 4 The position shown. At this time, the width d of the spacer 210c. 30 and the width d of spacer 210d 40 The same. At this point, for example, by adjusting the width of spacer 210c to width d... 31 Adjust the width of spacer 210d to width d. 41 (>d 31 This adjusts the trajectory L of the holding member 210a (the relative position of the probe body 201 and the holding member 210a) to, for example... Figure 5The positional relationship is shown.

[0108] In Embodiment 3 described above, the position adjustment structure of the probe body 201 and the holding member 210a is changed compared to Embodiment 1. However, since the behavior of the handling device itself remains unchanged during use, the same effect as Embodiment 1 can be obtained.

[0109] (Implementation Method 4)

[0110] Next, refer to Figures 17-19 Description of Implementation Method 4. Figure 17 and Figure 18 This diagram shows the structure of the main parts of the treatment device according to Embodiment 4 of the present invention. Furthermore, the overall structure of the treatment system in Embodiment 4 is the same as that of Treatment System 1 described above, except for the adjustment mechanism that changes the relative position of the probe body and the clamp member; therefore, its description is omitted. Hereinafter, a structure different from Embodiment 1 will be described.

[0111] The treatment device of this embodiment 4 replaces the first main body 21 of the treatment device 2 described above and has a first main body 21C. The first main body 21C has a clamping member 210C and a gripped part 211. In addition, the clamping member 210C has a gripping member 210a at its front end, but... Figure 17 The diagram shows the structure with the holding member 210a disassembled.

[0112] The clamp member 210C rotates around the central axis of the shaft member 23, and together with the probe body 201, grips the object part. The clamp member 210C is connected to the gripped part 211 at the other end.

[0113] The clamping member 210C has a first main body 210e connected to the gripped part 211, a second main body 210f rotatable relative to the first main body 210e, and a rotating shaft 210g that connects the second main body 210f rotatably relative to the first main body 210e. The length axis N1 (rotation axis) of the rotating shaft 210g is parallel to the central axis of the shaft member 23. Figure 18 The axis N2 shown extends in different directions. For example, the length axis of the rotating shaft 210g extends in a direction perpendicular to the central axis of the shaft member 23. The second main body 210f is rotatable about the rotating shaft 210g and is fixed in a set position. The rotating shaft 210g moves the first main body 210e in a plane that intersects the directions of the probe body 201 and the clamp member 210 facing each other and is orthogonal to the rotating shaft 210g. In this embodiment 4, the first main body 210e, the second main body 210f, and the rotating shaft 210g constitute an adjustment mechanism.

[0114] Figure 19This diagram illustrates the adjustment method according to Embodiment 4 of the present invention. When the second main body portion 210f is rotated about the rotation axis portion 210g, the second main body portion 210f is displaced relative to the first main body portion 210e in the direction of arrow Q4. This displacement adjusts the relative position between the probe body 201 and the holding member 210a, and the second main body portion 210f is fixed at the desired positional relationship.

[0115] In Embodiment 4 described above, the position adjustment structure of the probe body 201 and the holding member 210a is changed compared to Embodiment 1. However, since the behavior of the treatment device itself remains unchanged after the adjustment, the same effect as Embodiment 1 can be obtained.

[0116] (Other implementation methods)

[0117] Next, refer to Figures 20-23 Other implementation methods will be described. Figure 20 and Figure 21 This is a diagram showing the structure of the main parts of the treatment device in other embodiments. Figure 22 and Figure 23 This is a cross-sectional view showing the structure of the main parts of the treatment device in other embodiments. Figure 22 It means Figure 20 The diagram shows the cross-section of line A-A. Figure 23 It means Figure 20 The diagram shows the cross-section along line B-B. Furthermore, the overall structure of the treatment system in this embodiment is the same as that of treatment system 1 described above, except for the adjustment mechanism that changes the relative position of the probe body and the clamp member; therefore, its description is omitted. Hereinafter, a structure different from the embodiment will be described.

[0118] The gripping member 210a includes: an electrode portion 2101, which is mounted on the main body of the clamping member 210 and functions as an electrode to supply electricity to the object portion when gripping it; and a cover 2102, which is mounted on the electrode portion 2101. An adhesive area R for attaching the cover 2102 is provided on the electrode portion 2101. 10 Bonding area R 10 It is set accordingly to the outer edge of the cover 2102.

[0119] In the side of the cover 2102 opposite to the electrode part 2101, its bonding area R 10 The corresponding outer edge is bonded to the electrode portion 2101. On the other hand, the cover 2102 is in the bonding area R 10 An internal space is formed between the electrode portion 2101 and the cover 2102. Specifically, the electrode portion 2101 and the cover 2102 are formed internally. Figure 22 The space R shown 20Therefore, the peripheral surfaces of the electrode portion 2101 and the cover 2102 are tightly sealed, making the interior a sealed state, and a space R is formed inside. 20 At this time, the bonding surface of the electrode portion 2101 to the cover 2102 is the same as the forming space R of the electrode portion 2101. 20 The forming surface forms an angle of 90° or more.

[0120] In other embodiments described above, liquid can be prevented from seeping into the cover 2102 by sealing the electrode portion 2101 and the outer peripheral surface of the cover 2102 in a tight manner, and by forming a space R inside... 20 This makes it difficult for the heat conducted to the electrode section 2101 to be conducted to the cover 2102.

[0121] Furthermore, a cover formed of a porous body can be provided on the main body of the clamp member 210. This cover has multiple independent internal spaces (air trapping). By installing this cover on the clamp member 210, heat conduction from the main body of the clamp member 210 to the cover can be suppressed. The cover (or the clamp member body and the cover) is formed using foam molding or a 3D printer.

[0122] This concludes the description of methods for implementing the present invention, but the present invention should not be limited to the embodiments described above. The present invention may include various embodiments not described herein.

[0123] Furthermore, in the above embodiments, examples of applying ultrasonic waves or supplying high-frequency power to the probe body were described, but this can be applied to structures that only apply ultrasonic waves without supplying high frequencies, as well as to handling devices that neither supply high frequencies nor apply ultrasonic waves.
