[0036] Figure 1 This diagram illustrates a schematic structure of an endoscope device 100, which is one aspect of the technology of the present invention. The endoscope device 100 includes: an endoscope 1; a main body 2, comprising a light source device 4 and a processor device 5 connected to the endoscope 1; and a display device 7 for displaying photographic images acquired through the endoscope 1, etc. Figure 1 In the example, endoscope 1 is a bronchoscope, but it is not limited to this.

[0037] The endoscope 1 includes: an insertion part 10 that is inserted into the body of the patient and is a long strip-shaped instrument extending in one direction; an operation part 11 provided with operation components for performing observation mode switching, image storage, forceps operation, suction operation, etc., provided at the base end of the insertion part 10; an angle control lever 12 provided adjacent to the operation part 11; and a universal plug 13, including a connector part 13A that connects the endoscope 1 to the connector connection part 4A of the light source device 4 for easy attachment and detachment.

[0038] The operating section 11 is provided with a treatment instrument inlet 112 for introducing treatment instruments for collecting living tissues such as cells or polyps. Additionally, although in Figure 1 The details are omitted, but various channels, such as treatment instrument channels and suction channels, are provided inside the operation unit 11 and the insertion unit 10 for inserting treatment instruments introduced from the treatment instrument inlet 112. The operation unit 11 includes a suction button 11A, etc. A suction hose (not shown) is connected to the suction button 11A, and this suction hose is connected to a suction device. When the suction button 11A is operated, fluid or the like is aspirated from the tip of the endoscope 1 into the suction hose and recovered by the suction device.

[0039] The insertion part 10 is composed of a flexible soft part 10A, a curved part 10B provided at the front end of the soft part 10A, and a front end part 10C that is harder than the soft part 10A provided at the front end of the curved part 10B. An imaging element and an imaging optical system are built into the front end part 10C of the endoscope.

[0040] The bending part 10B is configured to bend in the up-down direction (A2 direction) by rotating the angle control lever 12 of the operation part 11 in the A1 direction. By bending the bending part 10B, the front end of the endoscope 10C can be oriented in the desired direction.

[0041] Inside the endoscope 1, a light guide, consisting of multiple bundled optical fibers, is provided from the endoscope tip 10C of the insertion section 10 to the connector section 13A. Light generated by the light source device 4 is guided from the connector section 13A to the light guide and then to the endoscope tip 10C, illuminating the subject through the illumination window provided at the endoscope tip 10C.

[0042] Furthermore, the structure of endoscope 1 is an example and is not limited to... Figure 1 The structure shown.

[0043] Figure 2 It means from Figure 1 The diagram shows a schematic cross-sectional view of the treatment system 20 used when the treatment instrument inlet 112 of the endoscope 1 is inserted into the treatment instrument channel of the endoscope 1. Figure 3 yes Figure 2A magnified view of the range X in the image. Figure 4 yes Figure 3 The cross-sectional view shown is taken from the CC direction. Figure 5 yes Figure 2 A magnified view of the range Y in the image.

[0044] The treatment system 20 includes: a treatment probe 30, which is a long strip-shaped treatment device extending in one direction; an ultrasonic probe 40, which is a long strip-shaped device extending in one direction; and an operating handle 50, configured to support the treatment probe 30 and the ultrasonic probe 40.

[0045] The treatment probe 30 has, for example, a hollow portion 31S comprising a cylindrical shape (see reference). Figure 3 and Figure 5 The tubular component 31. The treatment probe 30 has a treatment section 32, the end of which, i.e., the front end section 31A (refer to) on one end side in the axial direction of the tubular component 31. Figure 3 The treatment probe 30 is arranged circumferentially thereon, and is a treatment device capable of freezing the tissue of the subject through the treatment section 32. The treatment probe 30 preferably uses a probe in which the treatment section 32 is made of metal, for example, and the Joule-Thomson effect is used to cool the treatment section 32.

[0046] The tubular component 31 has, for example, a first space SP1 with a circular cross-section and a second space SP2 surrounding the first space SP1. An opening 31K connecting the first space SP1 and the second space SP2 is provided in the handling section 32 of the tubular component 31. The tubular component 31, except for the handling section 32, is made of, for example, resin or an elastomer.

[0047] like Figure 5 As shown, the first space SP1 is connected to the gas supply pipe 34 for cooling the processing unit 32. Figure 2 As shown, a generally T-shaped gripping part 33 is fixed to the base end 31B on the other end side in the axial direction of the tubular component 31, and a supply pipe 34 is provided inside the gripping part 33. The supply pipe 34 is connected to the treatment probe control device 300. The treatment probe control device 300 performs various controls such as driving the treatment unit 32 (injection of cooling gas).

[0048] Gas supplied from supply pipe 34 is supplied to second space SP2 through opening 31K via first space SP1. During the flow of gas from first space SP1 to second space SP2, the treatment section 32 is cooled by the Joule-Thomson effect. Gas flowing into second space SP2 is discharged to exhaust pipe (not shown). The treatment section 32 is arranged annularly around the hollow portion 31S, thus allowing freezing of tissue within a 360-degree radius around the tip 31A of the treatment probe 30.

[0049] like Figure 3 As shown, a front opening 312A connected to the hollow portion 31S is provided on the end face 312, i.e., the front end face 312, on one end side in the axial direction of the tubular component 31. Figure 5 As shown, a base end opening 311A ​​connected to the hollow part 31S is provided on the end face 311 on the other end side in the axial direction of the tubular component 31, i.e., the base end face 311.

[0050] The ultrasonic probe 40 is used with the base opening 311A ​​of the disposal probe 30 inserted into the hollow portion 31S. The inner diameter of the tubular component 31 is preferably larger than the outer diameter of the ultrasonic probe 40.

[0051] like Figure 3 As shown, an ultrasonic transceiver 42 is provided on a portion of the outer circumferential surface of the generally cylindrical front end portion 41 at one end of the ultrasonic probe 40. The ultrasonic transceiver 42 is configured, for example, by arranging multiple ultrasonic transducers, and is capable of transmitting ultrasonic waves radially within a specific range in the radial direction of the front end portion 41. The ultrasonic transceiver 42 may also be composed of a single ultrasonic transducer.

[0052] A rotating shaft 43 is provided inside the ultrasonic probe 40, with one end connected to the ultrasonic transceiver 42. The rotating shaft 43 extends in a direction that intersects (preferably orthogonal) the emission direction of the ultrasonic waves from the ultrasonic transceiver 42 (the axial direction of the ultrasonic probe 40), and the other end is connected to a rotating component (not shown). By rotating this rotating component, the rotating shaft 43 rotates, allowing the transmission range of the ultrasonic waves based on the ultrasonic transceiver 42 to be switched by rotating circumferentially around the front end 41. In this way, by configuring the ultrasonic transceiver 42 to be rotatable, an ultrasonic image of the subject within a 360-degree range around the front end 41 can be obtained based on the echo received by the ultrasonic transceiver 42.

[0053] Furthermore, the ultrasonic transceiver 42 can be arranged in a ring shape when viewed along the axial direction of the tubular member 31. By arranging the ultrasonic transceiver 42 in a ring shape, an ultrasonic image of the subject within a 360-degree range around the front end 41 can be easily obtained based on the echo received by the ultrasonic transceiver 42. When the ultrasonic transceiver 42 is arranged in a ring shape, there is no need for a rotating shaft 43 and a rotating component.

[0054] The ultrasonic probe 40 is provided with a wiring assembly that is electrically connected to the ultrasonic transceiver 42. This wiring assembly is connected to the ultrasonic probe control device 400, which controls the ultrasonic transceiver 42, generates and displays ultrasonic images, etc.

[0055] The operating handle 50 is a long, thin cylindrical shape with a receiving space that can accommodate a portion of the treatment probe 30. The operating handle 50 has a cylindrical connecting part 51 at its front end, which can be connected to the metal mold 112A provided in the treatment instrument inlet 112 of the endoscope 1 by fitting or the like.

[0056] The operating handle 50 also has a cylindrical shaft member 52, one end of which is supported by a connecting portion 51 and extends to the side opposite to the connecting portion 51. In the shaft member 52, a flange portion 52a is provided at the end on the side of the connecting portion 51, and a flange portion 52b is provided at the end on the side opposite to the connecting portion 51. The flange portion 52a is inserted into and fixed inside the connecting portion 51. A tubular member 31 extends through the entire interior of the shaft member 52. The tubular member 31, located further forward than the flange portion 52a of the shaft member 52, passes through the interior of the connecting portion 51 and is inserted into the metal die 112A connected to the connecting portion 51.

[0057] When using the treatment system 20, the treatment probe 30, which extends to the outside of the connection part 51, is inserted from its front end 31A into the treatment instrument channel 1A of the endoscope 1 via the metal nozzle 112A. In this state, the connection part 51 is connected to the metal nozzle 112A. The connection part 51 is configured to connect to the treatment instrument inlet 112 when the tubular member 31 is inserted from the front end 31A side into the treatment instrument inlet 112 of the endoscope 1.

[0058] The operating handle 50 also includes a cylindrical slider 53, which is slidably connected to the outer peripheral surface of the flange portion 52a and flange portion 52b in the shaft member 52 along the axial direction of the shaft member 52. An opening is provided on the outer peripheral surface of the slider 53 at the end on the connecting portion 51 side. A fixing member 57, such as a screw, is inserted into this opening to fix (lock) the relative position of the slider 53 with respect to the shaft member 52. When the locking based on the fixing member 57 is released, the slider 53 is configured to abut against the flange portion 52b on its inner wall. Figure 2 The position shown is within a distance L1 between the position where the end face of the connecting part 51 abuts against the connecting part 51 and the position where the connecting part 51 abuts against the connecting part 51.

[0059] On the slider 53, in a state where the end face on the connecting portion 51 abuts against the flange portion 52a (the position of the shaft member 52 in this state is indicated by the dashed line in the figure), an opening 53K is provided on the outer peripheral surface further from the base end than where the flange portion 52b is located. A holding portion 33 is provided at the location where the opening 53K is provided. A portion of the holding portion 33 protrudes outward from the opening 53K. The holding portion 33 is fixed to the tubular member 31.

[0060] Inside the slider 53, on the front end side of the adjacent gripping part 33 ( Figure 2On the left side of the tubular component 31, a support mechanism 55 is provided to support the base end 31B of the tubular component 31. The support mechanism 55 includes a locking mechanism, etc., and supports the treatment probe 30 so that it can move only a predetermined distance along the axial direction of the tubular component 31. For example, the operator can hold the probe 30 by gripping the handle 33. Figure 3 Moving to the left in the middle enables the tubular component 31 (i.e., the treatment probe 30) to move only a specified distance to its front end side and maintain that state.

[0061] A support member 56 for supporting the ultrasonic probe 40 is provided in the slider 53, closer to the base end than the holding part 33. The support member 56 is made of annular rubber or the like, which fits into an opening provided on the base end face of the slider 53, and the ultrasonic probe 40 can be inserted through it. The hollow part of the support member 56 is reduced by tightening screws or the like (not shown), so that it can be fixed to and supported by the inserted ultrasonic probe 40. The ultrasonic probe 40, inserted through the support member 56, is inserted through the hollow part 31S of the tubular member 31 supported by the support mechanism 55, and is inserted to the front end of the tubular member 31.

[0062] A support mechanism 58 for supporting the ultrasonic probe 40 is provided between the holding part 33 and the support member 56 in the slider 53. The support mechanism 58 includes a snap-fit ​​mechanism, etc., and supports the ultrasonic probe 40 so that it can move only a predetermined distance along its axial direction. For example, the operator can move the support mechanism 58 towards... Figure 3 Moving the probe to the right allows the ultrasonic probe 40 to move only a specified distance toward its base.

[0063] In the treatment system 20, the treatment probe 30 and the grip 33 are preferably configured to be detachable from the operating handle 50. When using the treatment system 20, first, prepare an assembly including the treatment probe 30 and the grip 33 fixed thereto, and insert this assembly into the interior of the slider 53 through the opening 53K. At this time, the treatment probe 30 is inserted sequentially from its front end through the slider 53, the shaft member 52, and the connecting portion 51, with most of the treatment probe 30 protruding outwards from the connecting portion 51. Alternatively, the treatment system 20 may be a structure where the operating handle 50, treatment probe 30, and grip 33 are integrated, allowing only the ultrasonic probe 40 to be attached and detached.

[0064] Next, the ultrasonic probe 40 is inserted into the support member 56 from the front end 41 side, and then inserted into the hollow portion 31S of the tubular member 31 supported by the support mechanism 55. Then, to become... Figure 3 As shown in the positional relationship, the front end of the ultrasonic probe 40 is inserted into the front end of the tubular component 31.

[0065] exist Figure 3In this example, the ultrasonic transceiver 42 is positioned on the side opposite to the base end face 311, closer to the axial direction of the tubular member 31 than the processing unit 32. Thus, the ultrasonic probe 40 is supported by the support member 56 and the support mechanism 58, with the ultrasonic transceiver 42 protruding from the front opening 312A towards the outside of the hollow portion 31S. The processing probe 30 can move along the axial direction within the slider 53 via the support mechanism 55. Therefore, by operating the handle 33, the position of the ultrasonic probe 40 can be changed, and the processing probe 30 can be moved only a predetermined distance towards the front end.

[0066] Figure 6 This indicates that the control department 33 is from Figure 3 The diagram shows the state in which the tubular component 31 is moved towards its front end. This is achieved by the gripping part 33 from... Figure 2 The position shown is moved a distance L2 towards the front end, as shown. Figure 6 As shown, it is possible to obtain a state in which the ultrasonic transceiver 42 retracts from the front opening 312A into the hollow portion 31S. Furthermore, in Figure 6 In the state shown, when viewed radially along the tubular component 31, the processing section 32 and the ultrasonic transceiver 42 have an overlapping portion, and the positions of the processing section 32 and the ultrasonic transceiver 42 in the axial direction of the tubular component 31 are approximately the same.

[0067] In addition, Figure 6 In the state shown, a portion of the front end 41 protrudes from the front opening 312A, but the tubular member 31 can also be movably supported by the support mechanism 55 in such a way that the front end 41 is entirely recessed into the hollow portion 31S.

[0068] Furthermore, the ultrasonic probe 40 can move along the axial direction within the slider 53 via the support mechanism 58. Therefore, by operating the support mechanism 58, the ultrasonic probe 40 can be moved only a distance L3 relative to the treatment probe 30 towards the base end (see reference). Figure 7 ).

[0069] Figure 7 This indicates that the ultrasonic probe 40 is from Figure 6 The diagram shows the state of the ultrasonic probe 40 moving towards the base end. The ultrasonic probe 40 is moved a distance L3 towards the base end by operating the support mechanism 58, as shown... Figure 7 As shown, it is possible to obtain a state in which the ultrasonic transceiver 42 is located closer to the base end face 311 than the processing unit 32. Figure 7 In the state shown, when viewed radially along the tubular component 31, preferably, the ultrasonic probe 40 is movably supported by the support mechanism 58 in such a way that the processing section 32 and the ultrasonic transceiver section 42 do not overlap.

[0070] Thus, the support mechanism 55, support component 56, and support mechanism 58 support the tubular component 31 and the ultrasonic probe 40 in a manner that allows for changing the relative position of the ultrasonic transceiver 42 of the ultrasonic probe 40 and the processing part 32 of the processing probe 30.

[0071] In the initial state where the support mechanisms 55 and 58 are not operated, the ultrasonic transceiver 42 protrudes from the front opening 312A of the tubular component 31. Alternatively, the processing system 20 may be provided with a limiting part that restricts the amount of protrusion of the ultrasonic transceiver 42 from the front opening 312A in this initial state.

[0072] For example, such as Figure 8 As shown, an annular protrusion 31T is provided on the inner circumferential surface of the front end portion 31A of the tubular component 31, and a protrusion 40T that abuts against the protrusion 31T is provided on the outer circumferential surface near the front end portion 41 of the ultrasonic probe 40. If the ultrasonic probe 40 is inserted into the hollow portion 31S of the tubular component 31, the protrusion of the ultrasonic transceiver 42 from the hollow portion 31S is maximized when the protrusion 31T abuts against the protrusion 40T, thus limiting the amount of protrusion. Figure 8 In the shown state, the ultrasonic probe 40 is fixed by the support member 56, allowing the positional relationship between the treatment probe 30 and the ultrasonic probe 40 to be controlled at the desired position. Figure 8 In the structure shown, the first limiting part is composed of the protrusion 31T and the protrusion 40T.

[0073] Furthermore, in the operating handle 50, the support position of the tubular component 31 can be fixed (the support mechanism 55 supports the tubular component 31 in a structure that prevents it from moving along the axial direction), or it can be configured to support only the ultrasonic probe 40 in a structure that allows it to move along the axial direction of the tubular component 31. Even with this configuration, by moving the ultrasonic probe 40 relative to the disposal probe 30, it is possible to achieve [the desired movement from the handle]. Figure 3 The state shown Figure 6 The transition from the state shown Figure 6 The state shown Figure 7 The transition of the state shown.

[0074] The ultrasonic probe 40 is inserted into the treatment probe 30 to obtain... Figure 3 After the state shown (the ultrasonic transceiver 42 protruding from the front opening 312A), the treatment probe 30, with the ultrasonic probe 40 inserted, is inserted from its front end into the treatment device inlet 112, and then the connecting part 51 is connected to the treatment device inlet 112. In this state, as... Figure 9As shown, the treatment probe 30 and ultrasonic probe 40 are recessed to a position closer to the interior of the endoscope front end 10C than the treatment instrument outlet 10Ca formed on the end face of the endoscope front end 10C. Additionally, the structure of the operating handle 50 can be modified to allow it to be positioned as... Figure 6 With the front end of the ultrasonic probe 40 inserted through the front end of the tubular component 31 in the positional relationship shown, the treatment probe 30 is inserted into the treatment device inlet 112 from its front end side.

[0075] Support mechanisms 55 and 58 are supported by slider 53. Therefore, if slider 53 is moved along shaft member 52 without support mechanisms 55 and 58 being operated, the treatment probe 30 and ultrasonic probe 40 can be moved from... Figure 9 The states shown move simultaneously. As a result, the treatment probe 30 and the ultrasonic probe 40 can be protruded from the treatment device outlet 10Ca, or the treatment probe 30 and the ultrasonic probe 40 can be retracted to the treatment device outlet 10Ca.

[0076] Thus, the moving mechanism is composed of shaft component 52, slider 53, support mechanism 55, support component 56 and support mechanism 58. While maintaining the relative position of ultrasonic transceiver unit 42 and processing unit 32, the moving mechanism moves tubular component 31 and ultrasonic probe 40 along the axial direction of tubular component 31.

[0077] The slider 53 can only move between the position abutting against the connecting part 51 and the position abutting against the flange part 52b. Therefore, the amount of protrusion of the tubular component 31 and the ultrasonic probe 40 from the treatment device outlet 10Ca is limited by the shaft component 52, the slider 53, and the connecting part 51. The shaft component 52, the slider 53, and the connecting part 51 constitute the second limiting part.

[0078] An example of a procedure using the endoscope 1 and procedure system 20 configured as described above will be described. First, the surgeon inserts the insertion part 10 of the endoscope 1 into the bronchus of the patient and moves the tip 10C of the endoscope to the desired location. Then, the procedure probe 30 and the ultrasound probe 40 of the procedure system 20, prepared as described above, are inserted into the procedure instrument inlet 112, and the connecting part 51 is connected to the procedure instrument inlet 112. Alternatively, the procedure system 20 can be installed on the endoscope 1 before the endoscope 1 is inserted into the patient.

[0079] Next, the surgeon slides the slider 53, causing the treatment probe 30 and the ultrasound probe 40 to protrude from the treatment device outlet 10Ca and advance into the bronchus. While confirming the ultrasound images generated by the output of each ultrasound transceiver 42, the surgeon aligns the ultrasound transceiver 42 with the target site P of the bronchial OS (see reference). Figure 10 ).exist Figure 10 In the state shown, the object part P and the ultrasonic transducer are aligned. Alternatively, it can also be made... Figure 6 The treatment probe 30 and ultrasonic probe 40, as shown, protrude from the treatment device outlet 10Ca and advance into the bronchus. After reaching the desired position, they change to... Figure 3 The state shown is such that the ultrasonic transceiver 42 is aligned with the target portion P of the bronchial OS.

[0080] Next, in Figure 10 In the indicated state, the surgeon slides the handle 33 towards the front end, as shown. Figure 11 As shown, while maintaining the position of the ultrasonic transceiver 42, the tubular component 31 is moved towards the front end 31A side to align the ultrasonic transceiver 42 with the processing unit 32.

[0081] Next, the surgeon operates the support mechanism 58, such as... Figure 12 As shown, the ultrasonic probe 40 is moved toward its base end.

[0082] Next, the surgeon operates the treatment unit 32 to treat the target site P. Specifically, the treatment unit 32 is cooled to freeze the target site P. Then, the surgeon maintains... Figure 12 With the treatment probe 30 and ultrasound probe 40 positioned as shown, the connecting part 51 is removed from the treatment instrument inlet 112, and the treatment probe 30 and ultrasound probe 40 are pulled out from the treatment instrument inlet 112, and the frozen tissue is collected. After freezing the target site P, the insertion part 10 of the endoscope 1 can be pulled out from the patient, and the insertion part 10, treatment probe 30, and ultrasound probe 40 are pulled out simultaneously.

[0083] Thus, according to the treatment system 20, even narrow areas such as the bronchus that cannot be observed in the endoscope 1 can be searched for by the ultrasonic probe 40, and the treatment unit 32 can treat the target area P (tissue collection) without removing the ultrasonic probe 40 from the endoscope 1.

[0084] For example, it is not necessary to insert the ultrasonic probe into the treatment instrument channel of the endoscope 1 to search for the target site P, then remove the ultrasonic probe from the treatment instrument channel, insert the treatment probe into the treatment instrument channel, advance the treatment unit to the target site P, and perform the treatment operation in this state (the replacement operation of the ultrasonic probe and the treatment probe). Therefore, the treatment can be performed simply and efficiently.

[0085] Furthermore, the tubular component 31 is slidable via the support mechanism 55. Figure 11In the shown configuration, the ultrasonic transceiver 42 and the processing unit 32 are positioned in almost identical locations. Therefore, the processing unit 32 can be accurately aligned with the target area P, enabling precise processing of the target area P identified by the ultrasonic image. Furthermore, compared to searching for the target area using radiation, the use of ultrasound eliminates interference with the subject and reduces processing costs.

[0086] Furthermore, according to the handling system 20, such as Figure 12 As shown, the processing unit 32 can be driven even when the ultrasonic transceiver 42 is not located inside the processing unit 32. Therefore, the cooling heat of the processing unit 32 can be prevented from affecting the ultrasonic transceiver 42, thereby improving the durability of the ultrasonic probe 40.

[0087] Furthermore, according to the treatment system 20, since the ultrasonic probe 40 can be inserted into or removed relative to the treatment probe 30, commercially available ultrasonic probes can be used, thereby reducing the system's implementation cost. In the treatment system 20, the operating handle 50 and the ultrasonic probe 40 can be cleaned and reused, while the treatment probe 30 can be designed as a disposable consumable. Alternatively, the ultrasonic probe 40 can be cleaned and disinfected for reuse, while the operating handle 50 and the treatment probe 30 can be designed as disposable consumables.

[0088] Furthermore, in the treatment system 20, changing the relative positions of the treatment probe 30 and the ultrasonic probe 40 is not essential. The treatment probe 30 and the ultrasonic probe 40 can be positioned, for example... Figure 3 The structure is fixed in the positional relationship shown. With this structure, after aligning the ultrasonic transceiver 42 with the target portion P, the sliding block 53 is used to move the processing probe 30 and the ultrasonic probe 40 towards... Figure 3 The processing unit 32 is moved to the left to the position where the ultrasonic transceiver 42 is located. In this state, the processing unit 32 is driven to freeze the target area P. In this structure, by providing a mechanism that allows the slider 53 to move only a distance equal to the distance between the processing unit 32 and the ultrasonic transceiver 42 towards the front end (e.g., by adding a scale to the slider 53), the target area P can be processed more accurately. Furthermore, with this structure, for example, as... Figure 13 As shown, it can be configured such that the front opening 312A is closed by a front end component 44 made of a material capable of transmitting ultrasonic waves. Figure 13 The front end portion 41 shown is inserted into the hollow part of the front end component 44 and fixed to the front end component 44 by fitting or bonding.

[0089] exist Figure 13In the structural example shown, it is assumed that the treatment system 20 is sold in a state where the treatment probe 30, operating handle 50, and ultrasonic probe 40 are assembled. However, the front-end component 44 can also be configured as a separate component, such as... Figure 3 As shown, after the ultrasonic probe 40 is inserted into the treatment probe 30, the assembly is embedded into the front end 41, thereby obtaining... Figure 13 The structure shown.

[0090] The aforementioned treatment probe 30 is not limited to a probe capable of freezing and collecting tissue; probes that collect tissue by other means can also be used. For example, the treatment section 32 can be modified into a brush-shaped treatment section. In this case, for example, it can be configured such that the brush is folded in normal conditions and unfolds and extends to a position where it can contact the target area P during treatment.

[0091] Furthermore, the processing unit 32 can also be configured as pliers. In this case, for example, it can be configured such that the pliers are folded in normal operation and unfolded and extended to a position where they can contact the target part P during processing.

[0092] In the above description, the ultrasonic transceiver unit 42 is configured to be able to rotate inside the ultrasonic probe 40, but it is not limited to this. For example, the ultrasonic probe 40 as a whole may be configured to be able to rotate about its axis.
