[0054] Hereinafter, embodiments of the ultrasonic treatment apparatus and the method for manufacturing the ultrasonic 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 following description of the drawings, the same or corresponding elements will be 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.

[0055] (Implementation Method)

[0056] Figure 1 This diagram schematically illustrates a treatment system according to one embodiment of the present invention. The 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.

[0057] The treatment device 2 applies heat to the object being held, performing actions such as burning, solidifying, or cutting. The heat applied to the object is either frictional heat generated by vibration or Joule heating generated by the application of a high-frequency current. The structure of the treatment device 2 will be described later.

[0058] 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.

[0059] The control device 4 supplies power to the oscillator unit 3 and the probe body 201, and controls the driving of the oscillator unit 3 or the supply of high-frequency current to the probe body 201. The control device 4 is composed of general-purpose processors such as CPUs (Central Processing Units), FPGAs (Field Programmable Gate Arrays), and ASICs (Application Specific Integrated Circuits) that perform specific functions.

[0060] The structure of treatment device 2 will be described below. Figure 2 It means Figure 1 A diagram of the front end structure of the treatment device shown. Figure 3 yes Figure 2 The cross-sectional view of the front-end structure shown. Figure 4 It means Figure 2 The diagram shows the structure of the main parts of the front-end structure.

[0061] 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.

[0062] The probe part 20 has a probe body 201 and a protective sleeve 202.

[0063] The first main body 21 has a clamping member 210 and a gripped part 211.

[0064] The second main body 22 has a connecting part 220 and a holding part 221.

[0065] In addition, 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.

[0066] The probe body 201 is constructed using a rod. The probe body 201 vibrates longitudinally in a direction parallel to its length, utilizing ultrasonic waves propagating from the vibrator 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, resulting in burning or solidification. The probe body 201 acts as a vibration transmission member.

[0067] The sheath 202 is cylindrical. The probe body 201 is penetrated through the sheath 202 and surrounds the probe body 201.

[0068] The clamp member 210 is rotatable relative to the probe portion 20. The clamp member 210 passes through the sheath 202 and rotates about an axis orthogonal to the length axis N1 of the sheath 202 (the central axis N2 described later). Furthermore, the clamp 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 clamp member 210. The clamp member 210 holds the gripping member 210a in a swing-free manner. The gripping member 210a rotates, for example, about an axis extending in a direction orthogonal to the length axis N1 of the sheath 202. Furthermore, the clamp member 210 is connected to the gripped portion 211 at the other end.

[0069] 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).

[0070] The connecting part 220 retains the sheath 202 and is connected to the oscillator unit 3.

[0071] The holding part 221 is the part that is held by the surgical operator. A through hole 221a is formed in the holding part 221 to engage with another part of the surgical operator's hand (e.g., index finger, middle finger).

[0072] The second main body 22 is provided with operation buttons 22a and 22b. For example, operation button 22a is used to generate ultrasonic vibrations in the probe body 201. Operation button 22b is used to supply a high-frequency voltage 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 a high-frequency voltage to the probe body 201 based on the input signal.

[0073] The shaft member 23 is cylindrical and is disposed through the sheath 202 and the clamp member 210. The shaft member 23 is held in the sheath 202. Furthermore, clamp members 210 are installed at both ends of the shaft member 23. The clamp members 210 are slidable relative to the shaft member 23 and rotatable relative to the sheath 202. Specifically, the shaft member 23 passes through the clamp members 210 at both ends, and the clamp members 210 are configured to rotate freely about a central axis N2. The central axis N2 is the central axis of the shaft member 23, which intersects the probe body 201 and is orthogonal to the length axis N1 of the sheath 202.

[0074] Furthermore, a through hole 231 is formed in the shaft member 23 for the probe body 201 to pass through. The through hole 231 forms a space for the probe body 201 to pass through.

[0075] Here, a bushing 201a is provided on the probe body 201. The bushing 201a abuts against the sheath 202 to maintain the positional relationship between the probe body 201 and the sheath 202 or to reduce friction (see reference). Figure 4 In this embodiment, the bushing 201a is provided at a position that abuts against the rear end side of the shaft member 23. Since the bushing 201a is in contact with the shaft member 23, rotation of the shaft member 23 about the central axis N2 can also be suppressed.

[0076] By operating the gripping parts 211 and 221, the processing device 2 can rotate the clamping member 210 relative to the probe body 201 around the axis member 23 (central axis N2). After the clamping member 210 is rotated and the object part is clamped by the probe body 201 and the gripping member 210a, if 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 part can be burned, coagulated, or cut.

[0077] Next, refer to Figures 5-8 The manufacturing method of the treatment device 2 is explained. Figures 5-8 Yes Figure 1 The diagram illustrates the manufacturing method of the treatment device shown.

[0078] First, prepare the protective sleeve 202 (refer to...). Figure 5 The sheath 202 has a first through hole 202a through which the probe body 201 passes and a second through hole 202b through which the shaft member 23 passes.

[0079] The clamp component 210 is configured relative to the sheath 202 (see reference). Figure 6The clamping member 210 has a first hole 210b through which the sheath 202 passes and a second hole 210c through which the shaft member 23 passes. The through directions of the first hole 210b and the second hole 210c are different and intersect each other. The second hole 210c has a hole shape extending from different sides of the first hole 210b. Here, the side of the first hole 210b corresponds to the wall portion (wall thickness) forming the hole. The clamping member 210 is positioned where the second hole 210c connects to the second through hole 202b.

[0080] Alternatively, a gripping part 211 may be installed on the clamp member 210 at this time.

[0081] Then, the shaft member 23 (see reference) is passed through the second through hole 202b and the second hole portion 210c. Figure 7 The clamp member 210 is rotatable relative to the sheath 202 by means of the shaft member 23. At this time, the shaft member 23 is configured such that the through direction of the through hole 231 is aligned with the through direction of the sheath 202.

[0082] After the shaft component 23 is installed, the probe body 201 penetrates the sheath 202 (see reference). Figure 8 At this time, the probe body 201 passes through the shaft member 23 via the through hole 231. In addition, the front end of the probe body 201 is exposed to the outside when it is disposed in the sheath 202.

[0083] Then, by attaching the gripping part 211 to the clamping member 210 and attaching the second main body part 22 to the sheath 202, the processing device 2 is manufactured.

[0084] In the embodiments of the present invention described above, a structure is provided in which the clamping member 210 is rotated about the central axis N2 by means of the shaft member 23 that passes through the sheath 202 and the clamping member 210. According to this embodiment, since the holding member 210a can be rotated freely relative to the probe body 201, which is a vibration transmission member, by means of the probe body 201, the sheath 202, the clamping member 210, and the shaft member 23, the clamping member can be installed in a rotatable manner while preventing interference between the vibration transmission member and the clamping member using a simple structure.

[0085] (Variation Example 1)

[0086] Next, refer to Figure 9 Example 1 illustrates a variation of the implementation method. Figure 9 This diagram illustrates the structure of the main components of the treatment apparatus in Modified Example 1. Furthermore, since the structure of the treatment system in this Modified Example 1 is the same as that of the treatment system 1 described above, except for the change in the arrangement of the bushing 201a, descriptions other than those of the bushing 201a are omitted. Hereinafter, structures different from the embodiment will be described.

[0087] In this modified example 1, the bushing 201a is located on the rear end side of the shaft member 23 and is located in a position that does not contact the shaft member 23.

[0088] In the modified example 1 described above, the position of the bushing 201a is changed relative to the above embodiment, but since the behavior of the processing device itself remains unchanged, the same effect as the embodiment can be obtained.

[0089] (Variation Example 2)

[0090] Next, refer to Figure 10 Example 2 illustrates a variation of the implementation method. Figure 10 This diagram illustrates the structure of the main components of the treatment apparatus in Modified Example 2. Furthermore, the structure of the treatment system in this Modified Example 2 is the same as that of the treatment system 1 described above, except for the change in the arrangement of the bushing 201a. Hereinafter, the structure differing from the embodiment will be described.

[0091] In this modified example 2, the bushing 201a is provided inside the shaft member 23. The bushing 201a abuts against the inner circumferential surface of the through hole 231 of the shaft member 23, determining the position of the probe body 201 relative to the sheath 202 and the shaft member 23.

[0092] In the modified example 2 described above, the position of the bushing 201a is changed relative to the above embodiment, but since the behavior of the processing device itself remains unchanged, the same effect as the embodiment can be obtained.

[0093] (Variation Example 3)

[0094] Next, refer to Figure 11 and Figure 12 Example 3 illustrates a variation of the implementation method. Figure 11 and Figure 12 This diagram illustrates the structure of the main components of the treatment device in Modified Example 3. Furthermore, the structure of the treatment system in this Modified Example 3 is the same as that of the treatment system 1 described above, except that shaft member 23 is replaced by shaft member 23A. Hereinafter, a structure different from the embodiment will be described.

[0095] The shaft member 23A is cylindrical. A notch 232, formed by cutting off the central portion, is formed in the shaft member 23A. The notch 232 forms a space through which the probe body 201 passes. The notch 232 is formed by cutting the central portion of the shaft member 23A into a partially connected state.

[0096] In the modified example 3 described above, the structure of the shaft member 23A is changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0097] (Variation Example 4)

[0098] Next, refer to Figure 13 Example 4 illustrates a variation of the implementation method. Figure 13 This diagram illustrates the structure of the main components of the treatment device in Modification 4. Furthermore, the structure of the treatment system in this Modification 4 is the same as that of the treatment system 1 described above, except that the shaft member 23 is replaced with shaft member 23B and the position of the bushing 201a is changed. Hereinafter, the structure different from the embodiment will be described.

[0099] The shaft member 23B is cylindrical. A through hole 231 is formed in the shaft member 23B for the probe body 201 to pass through. In addition, one end of the shaft member 23B is convex. Specifically, the shaft member 23B has a protrusion 233 at one end that extends cylindrically with a diameter smaller than that of the other parts. When assembling the handling device, the protrusion 233 passes through the clamp member 210 (the second hole 210c at one end in the direction of the central axis N2), holding the clamp member 210 in a position to rotate freely. In addition, in the modified example 4, the second hole 210c has a shape corresponding to the connecting portion of the shaft member 23B.

[0100] Furthermore, in this modified example 4, the bushing 201a is located on the front end side of the shaft member 23B. The bushing 201a abuts against the inner circumferential surface of the sheath 202 at the front end side of the shaft member 23B, thus determining the position of the probe body 201 relative to the sheath 202.

[0101] In the modified example 4 described above, the structure of the shaft member 23B and the position of the bushing 201a are changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0102] Furthermore, the configuration of bushing 201a in Modified Example 4 can be applied to the Implementation Method and Modified Example 1.

[0103] (Variation Example 5)

[0104] Next, refer to Figures 14-16 Example 5 illustrates a variation of the implementation method. Figure 14 This is an exploded perspective view illustrating the structure of the main parts of the treatment device in Modified Example 5. Figure 15 and Figure 16 This diagram illustrates the structure of the main parts of the treatment device in Modification 5. Furthermore, the structure of the treatment system in this Modification 5 is the same as that of the treatment system 1 described above, except that the shaft member 23 is replaced by the shaft member 23C and the sheath 202 is replaced by the sheath 202A. Hereinafter, a structure different from the embodiment will be described.

[0105] The shaft member 23C is columnar. The shaft member 23C has a main body portion 234 through which the probe body 201 passes, a first end portion 235 located at one end of the main body portion 234 and holding the clamp member 210, and a second end portion 236 located at the other end of the main body portion 234 and holding the clamp member 210. A through hole 234a for the probe body 201 to pass through is formed in the main body portion 234. Furthermore, the main body portion 234 extends in a prismatic shape along the central axis N2 direction. In modified example 5, the second hole portion 210c has a shape corresponding to the first end portion 235 and the second end portion 236 of the shaft member 23C.

[0106] The sheath 202A is cylindrical. A first through hole 202a for the probe body 201 to pass through and a second through hole 202c for the shaft member 23C to pass through are formed in the sheath 202A. The second through hole 202c has a prismatic inner wall surface that corresponds to the shape of the body 234.

[0107] If the shaft member 23C penetrates the sleeve 202A, then the main body 234 is fitted with the second through hole 202c (see reference). Figure 15 This engagement suppresses the rotation of shaft member 23C about the central axis N2.

[0108] After the shaft component 23C is installed, the probe body 201 penetrates the sheath 202A (see reference). Figure 16 At this time, the probe body 201 passes through the shaft member 23C via the through hole 234a.

[0109] Then, by attaching the gripping part 211 to the clamping member 210 and attaching the second main body part 22 to the sheath 202A, a treatment device is manufactured.

[0110] In the modified example 5 described above, the structure of the shaft member 23C and the sleeve 202A is changed compared to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0111] In modified example 5, since the shaft member 23C is fitted with the sleeve 202A, the rotation of the shaft member 23C relative to the sleeve 202A is suppressed, thus further suppressing the misalignment of the through hole 234a during assembly.

[0112] (Variation Example 6)

[0113] Next, refer to Figure 17 Example 6 illustrates a variation of the implementation method. Figure 17This is an exploded perspective view illustrating the structure of the main parts of the treatment device in Modified Example 6. Furthermore, the structure of the treatment system in this Modified Example 6 is the same as that of the treatment system 1 described above, except that the shaft member 23 is replaced by the shaft member 23D and the sheath 202 is replaced by the sheath 202B. Hereinafter, a structure different from the embodiment will be described.

[0114] The shaft member 23D is columnar. The shaft member 23D has a main body portion 237 through which the probe body 201 passes and holds the clamp member 210 at one end; an end portion 238 located at the other end of the main body portion 237 and holding the clamp member 210; and a prismatic portion 239 located between the main body portion 237 and the end portion 238 and is prismatic in shape. A through hole 237a is formed in the main body portion 237 through which the probe body 201 passes. Furthermore, in Modification 6, the second hole portion 210c has a shape corresponding to the main body portion 237 and the end portion 238 of the shaft member 23D.

[0115] The sheath 202B is cylindrical. A first through hole 202a for the probe body 201 to pass through and a second through hole 202d for the shaft member 23D to pass through are formed in the sheath 202B. One end of the second through hole 202d has a prismatic inner wall surface that corresponds to the shape of the prismatic portion 239.

[0116] When assembling the handling device, as the shaft member 23D passes through the sleeve 202B, the prism portion 239 engages with the second through hole 202d. This engagement suppresses the rotation of the shaft member 23D about the central axis N2.

[0117] In the modified example 6 described above, the structure of the shaft member 23D and the sleeve 202B is changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0118] In Modification 6, since the shaft member 23D is fitted with the sleeve 202B, the rotation of the shaft member 23D relative to the sleeve 202B is suppressed, thus further suppressing the misalignment of the through hole 237a during assembly.

[0119] (Variation Example 7)

[0120] Next, refer to Figure 18 and Figure 19 Example 7 illustrates a variation of the implementation method. Figure 18 and Figure 19 This diagram illustrates the structure of the main components of the treatment device in Modification 7. Furthermore, the structure of the treatment system in this Modification 7 is the same as that of the treatment system 1 described above, except that shaft member 23 is replaced by shaft member 23E. Hereinafter, a structure different from the embodiment will be described.

[0121] The shaft member 23E is cylindrical. A flat portion 240 is formed in the shaft member 23E by cutting a portion of the side surface of the cylinder. When disposed in the sleeve 202, the flat portion 240 abuts against a pin 241 that penetrates a portion of the sleeve 202. By the flat portion 240 abutting against the pin 241 inside the sleeve 202, rotation of the shaft member 23E about the central axis is suppressed.

[0122] In Variation 7 described above, the structure of the shaft member 23E is changed compared to the embodiment described above. However, since the behavior of the handling device itself remains unchanged, the same effect as in the embodiment can be obtained.

[0123] In modified example 7, since the shaft member 23E abuts against the pin 241, the rotation of the shaft member 23E relative to the sleeve 202 is suppressed, thus further suppressing the misalignment of the through hole 231 during assembly.

[0124] Alternatively, in variation 7, pin 241 may not be used, and the rotation of shaft member 23E may be suppressed by making the shape of the second through hole 202b match the shape of shaft member 23E.

[0125] (Variation Example 8)

[0126] Next, refer to Figure 20 Example 8 illustrates a variation of the implementation method. Figure 20 This diagram illustrates the structure of the main parts of the treatment device in Modified Example 8. Furthermore, Modified Example 8 replaces Shaft Member 23E of Modified Example 7 with Shaft Member 23F.

[0127] The shaft member 23F is columnar. A recess 240A is formed on the side of the shaft member 23F for the pin 241 to abut.

[0128] In the modified example 8 described above, the structure of the shaft member 23F is changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0129] Furthermore, in Modification 8, since the recess 240A of the shaft member 23F abuts against the pin 241, the rotation of the shaft member 23F relative to the sheath 202 is suppressed, thus preventing misalignment of the through hole 231 during assembly. Moreover, since Modification 8 only has a flat portion (recess 240A) formed at the abutment portion of the pin 241, compared to the flat portion 240 of Modification 7, it further ensures sliding relative to the clamp member 210 and watertightness relative to the sheath 202.

[0130] (Variation Example 9)

[0131] Next, refer to Figure 21 Example 9 illustrates a variation of the implementation method. Figure 21This diagram illustrates the structure of the main components of the treatment device in Modification 9. Furthermore, the structure of the treatment system in this Modification 9 is identical to that of the treatment system 1 described above, except that shaft member 23 is replaced by shaft member 23G; therefore, the description is omitted. Hereinafter, a structure different from the embodiment will be described.

[0132] The shaft member 23G is cylindrical. Bearings 242 are provided at both ends of the shaft member 23G. When the shaft member 23G is assembled into the handling device, the bearings 242 are held in place by the clamp member 210. Therefore, the clamp member 210 rotates smoothly using the bearings 242. Alternatively, as long as the rotation centers of the bearings are aligned and the clamp member can be mounted to rotate freely, a structure with bearings of different sizes at both ends can also be provided.

[0133] In the modified example 9 described above, the structure of the shaft member 23G is changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0134] In Modification 9, the bearing 242 is used to suppress the rotation of the shaft member 23G, excluding the bearing 242, caused by the rotation of the clamp member 210. This suppresses friction between the shaft member 23G and the sleeve 202, improving the durability of the handling device.

[0135] (Variation Example 10)

[0136] Next, refer to Figure 22 and Figure 23 Example 10 illustrates a variation of the implementation method. Figure 22 This is a cross-sectional view illustrating the structure of the main parts of the treatment device in Modified Example 10. Figure 23 This is a perspective view illustrating the structure of the main parts of the treatment device in Modified Example 10. Furthermore, the structure of the treatment system in this Modified Example 10 is the same as that of the treatment system 1 described above, except that the shaft member 23 is replaced by the shaft member 23H. Hereinafter, a structure different from the embodiment will be described.

[0137] The shaft member 23H is columnar. A through hole 231A is formed therethrough for the probe body 201 to pass through. The through hole 231A forms a space through which the probe body 201 passes. An insulating film is formed on the inner wall surface of the through hole 231A. Therefore, the probe body 201 is insulated from the sheath 202 and the clamp member 210. Furthermore, the through hole 231A is not limited to an insulating film, as long as its inner wall surface is insulating. For example, an insulating cylindrical member can be installed on the shaft member 23H, and the hole in this cylindrical member can be designated as the through hole 231A.

[0138] In the modified example 10 described above, the structure of the shaft member 23H is changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0139] In Modification 10, since the probe body 201 is insulated from the sheath 202 and the clamp member 210, it is possible to reliably insulate the probe body 201, which forms one electrode when a high-frequency current is applied, from the clamp member 210 (and the sheath 202), which forms the other electrode, thereby enabling the treatment.

[0140] (Variation Example 11)

[0141] Next, refer to Figure 24 Example 11 illustrates a variation of the implementation method. Figure 24 This diagram illustrates the structure of the main parts of the treatment device in Modification 11. Furthermore, the structure of the treatment system in this Modification 11 is the same as that of the treatment system 1 described above, except that the shaft member 23 is replaced by shaft member 23I. Hereinafter, a structure different from the embodiment will be described.

[0142] The shaft member 23I is columnar. It has a through hole 231B through which the probe body 201 passes. The through hole 231B forms a space through which the probe body 201 passes. The diameters of the openings at the two ends of the through hole 231B are different. Specifically, the diameter d1 of the opening located at the front end of the probe body 201 is larger than the diameter d2 of the opening located at the base end of the probe body 201. Furthermore, the inner circumferential surface connected to the openings at both ends can be either of progressively different diameters or conical.

[0143] Here, when the probe body 201 is bent while holding the object, the deflection on the front end side of the probe body 201 is greater than the deflection on the base end side. By making the diameter d1 of the opening on the front end side of the probe body 201 in the through hole 231B larger than the diameter d2 of the opening on the base end side, the difference in deflection of the probe body 201 can be accommodated.

[0144] In the modified example 11 described above, the structure of the shaft member 23I is changed relative to the above embodiment, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0145] Furthermore, in modified example 11, since the diameter d1 of the opening on the front end side of the probe body 201 in the through hole 231B is larger than the diameter d2 of the opening on the base end side, the interference between the shaft member 23I and the probe body 201 caused by the difference in deflection can be suppressed.

[0146] (Variation Example 12)

[0147] Next, refer to Figure 25 and Figure 26 Example 12 illustrates a variation of the implementation method. Figure 25 This is a diagram illustrating the structure of the main parts of the treatment device in Modified Example 12. Figure 26 This is a cross-sectional view illustrating the structure of the main parts of the treatment device in Modified Example 12. Furthermore, the treatment system in this Modified Example 12 also includes a cover 250 that partially covers the clamp member 210. Apart from this cover 250, it is the same as the treatment system 1 described above, and therefore its description is omitted. Hereinafter, a structure different from the embodiment will be described.

[0148] The cover 250 extends from the end on the side of the gripped portion 211 to cover a portion of the clamping member 210, thereby covering the second hole portion 210c. Furthermore, the cover 250 covers both ends of the shaft member 23 (see reference). Figure 26 ).

[0149] In the modified example 12 described above, the structure is changed to include a cover 250, but since the behavior of the handling device itself remains unchanged, the same effect as the embodiment can be obtained.

[0150] Furthermore, in Modification 12, since the cover 250, which is installed on the clamp member 210 and covers a portion of the clamp member 210, covers both ends of the shaft member 23, it is possible to prevent the shaft member 23 from detaching.

[0151] (Variation Example 13)

[0152] Next, refer to Figures 27-30 Example 13 illustrates a variation of the implementation method. Figure 27 and Figure 28 This is a diagram illustrating the structure of the main parts of the treatment device in Modified Example 13. Figure 29 This is a cross-sectional view illustrating the structure of the main parts of the treatment device in Modified Example 13. Figure 30 It is magnification Figure 29 A partial diagram of the structure is shown. Furthermore, the treatment system of this modified example 13 also includes a watertight component 251, which is identical to the treatment system 1 described above, except for the watertight component 251; therefore, its description is omitted. Hereinafter, a structure different from the embodiment will be described.

[0153] Watertight components 251 are respectively provided at both ends of the second through hole 202b of the sheath 202 (refer to...) Figure 29 The watertight component 251 is annular (see reference). Figure 28 The watertight component 251 is pressed against the shaft component 23 and the sheath 202, making the space between the shaft component 23 and the sheath 202 watertight. Specifically, the outer peripheral surface of the watertight component 251 and the inner peripheral surface of the sheath 202 are at position P. 11 P 21 Close contact. Furthermore, the inner circumferential surface of the watertight member 251 and the outer circumferential surface of the shaft member 23 are at position P.12 P 22 Close contact. The watertight component 251 is in close contact with each component through line contact or surface contact.

[0154] In manufacturing the treatment device of Modified Example 13, firstly, a watertight component 251 is disposed on the sheath 202. Then, in accordance with the embodiment (see...),... Figures 6-8 )same.

[0155] In the modified example 13 described above, the structure is changed to include a watertight component 251, but since the behavior of the treatment device itself remains unchanged, the same effect as the embodiment can be obtained.

[0156] Furthermore, in modified example 13, since the watertight member 251 makes the shaft member 23 and the sleeve 202 watertight, it is possible to prevent liquids (such as body fluids, blood) from seeping into the sleeve 202.

[0157] 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. Embodiments and variations can be appropriately combined.

[0158] Furthermore, in the above embodiments, an example of supplying ultrasonic waves or high-frequency power to the probe body was described, but it is also possible to have a structure that only supplies ultrasonic waves without supplying high frequency.

[0159] Furthermore, in the above embodiment, an example was described where the shaft member passes through the second hole of the clamp member, but it could also be a structure that blocks one end of the second hole. In this case, the shaft member is disposed to abut against the blocking portion of the second hole of the clamp member.
