Technical Field

[0001] This invention relates to a treatment device. Background Technology

[0002] There are known treatment devices that treat a part of a biological tissue that is the object of treatment (hereinafter referred to as the object part) by applying treatment energy such as ultrasonic energy to the object part (see, for example, Patent Document 1).

[0003] The treatment device described in Patent Document 1 includes a housing and an operating button. The operating button is positioned so that it is exposed outside the housing from the side, and is activated by a treatment operation performed by a surgeon or other operator. Furthermore, this treatment operation is the application of treatment energy to the target area.

[0004] Furthermore, in the treatment apparatus described in Patent Document 1, the first treatment operation and the second treatment operation shown below can be performed as treatment operations.

[0005] The first operation is to press the switch element by moving the operation button toward the switch element along the straight first axis.

[0006] The second operation is to press the operation button in a direction intersecting the first axis, causing the operation button to rotate around the second axis, which is orthogonal to the first axis, thus pressing the switch element.

Detailed Implementation

[0027] Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described below. Furthermore, in the accompanying drawings, the same reference numerals are used to label the same parts.

[0028] [Overall Structure of the Disposal System]

[0029] Figure 1 This is a diagram illustrating the processing system 1 of the implementation method.

[0030] The treatment system 1 treats the target area (hereinafter referred to as the target area) of a biological tissue by applying treatment energy. In this embodiment, the treatment energy is ultrasonic energy and high-frequency energy. Furthermore, treatments that can be performed using the treatment system 1 of this embodiment include coagulation (sealing) or cutting of the target area. Coagulation and cutting can also be performed simultaneously. Figure 1 As shown, the treatment system 1 includes a treatment device 2 and a control device 3.

[0031] [Structure of the treatment equipment]

[0032] Furthermore, in the following description of the structure of the treatment device 2, the XYZ coordinate axes (X-axis, Y-axis, and Z-axis) will be used, which are mutually orthogonal. The X-axis is perpendicular to the central axis Ax of axis 10. Figure 1 The Y-axis is parallel to the axis. Figure 1 The axes are orthogonal to the plane of the paper. The Z-axis is along... Figure 1 The axis in the vertical direction. Furthermore, hereafter, one side (+X axis side) along the central axis Ax will be referred to as the front end side Ar1, and the other side (-X axis side) will be referred to as the base end side Ar2.

[0033] Treatment device 2 is an ultrasonic treatment device that treats a target area by applying ultrasonic energy and high-frequency energy to the target area. For example... Figure 1 As shown, the treatment device 2 includes a handheld component 4 and an ultrasonic transducer 5.

[0034] like Figure 1 As shown, the handheld component 4 includes a housing 6, a movable handle 7, a first operation button 81, a second operation button 82, a knob 9, a shaft 10, a clamping component 11, and a vibration transmission component 12.

[0035] The housing 6 supports the entire handling device 2. (Example) Figure 1 As shown, the housing 6 includes a generally cylindrical housing body 61 coaxial with the central axis Ax, and a housing extending from the housing body 61 toward the -Z axis side (in... Figure 1 The fixed handle 62 extends from the lower side and is held by the operator, such as the surgeon.

[0036] The movable handle 7 accepts both closing and opening operations performed by the user, such as a surgeon. Furthermore, the movable handle 7 moves towards the fixed handle 62 in response to the closing operation, and moves away from the fixed handle 62 in response to the opening operation.

[0037] like Figure 1 As shown, the first operation button 81 and the second operation button 82 are arranged so that they are exposed to the outside from the side of the front end Ar1 of the fixed handle 62 and are arranged along the Z-axis. The first operation button 81 and the second operation button 82 are output buttons that receive treatment operations performed by an operator such as a surgeon. This treatment operation is the operation of applying treatment energy to the target area.

[0038] Furthermore, the first operation button 81 and the second operation button 82 have substantially the same structure. Moreover, without needing to specifically distinguish between the first operation button 81 and the second operation button 82, the first operation button 81 and the second operation button 82 are referred to together as operation button 8.

[0039] Furthermore, the detailed structure of operation button 8 will be explained in the section on "Structure of Operation Buttons" which will be described later.

[0040] Knob 9 has a roughly cylindrical shape coaxial with the central axis Ax, such as Figure 1 Ar1 is shown located on the front end side of the housing body 61. Furthermore, the knob 9 accepts rotational operation by the user, such as a surgeon. Through this rotational operation, the knob 9 rotates relative to the housing body 61 about the central axis Ax. In addition, by rotating the knob 9, the shaft 10, the clamping member 11, and the vibration transmission member 12 also rotate about the central axis Ax.

[0041] Shaft 10 is a cylindrical tube made of conductive materials such as metal.

[0042] Furthermore, the clamping member 11 is axially supported at the end of the front end Ar1 of the shaft 10 in such a way that it can rotate about a first rotation axis Rx1 as the center, the first rotation axis Rx1 being along the axis of rotation. Figure 1 Extend in directions orthogonal to the paper surface.

[0043] Although specific illustrations are omitted here, an opening and closing mechanism is provided in the housing 6 and the shaft 10. This mechanism causes the clamp component 11 to rotate about the first rotation axis Rx1 in accordance with the opening and closing operations performed by the operator such as the surgeon on the movable handle 7.

[0044] Furthermore, the clamping component 11 utilizes the opening and closing mechanism to the end 121 (hereinafter referred to as the handling part 121) of the front end Ar1 of the vibration transmission member 12. Figure 1 The opening and closing mechanism controls the object between itself and the processing unit 121.

[0045] In addition, at least a portion of the clamping component 11 is made of a conductive material.

[0046] The vibration transmission component 12 is made of a conductive material and has an elongated shape extending linearly along the central axis Ax. Furthermore, as... Figure 1 As shown, the vibration transmission member 12 extends through the interior of the shaft 10 with the disposal part 121 protruding to the outside. At this time, the end of the base side Ar2 of the vibration transmission member 12 is mechanically connected to the ultrasonic transducer 52 constituting the ultrasonic transducer 5.

[0047] Furthermore, the vibration transmission member 12 transmits the ultrasonic vibration generated by the ultrasonic transducer 5 from the end of the base side Ar2 to the processing unit 121. In this embodiment 1, the ultrasonic vibration is a longitudinal vibration that vibrates in the direction along the central axis Ax.

[0048] like Figure 1 As shown, the ultrasonic transducer 5 includes a TD (transducer) housing 51 and an ultrasonic transducer 52.

[0049] The TD housing 51 supports the ultrasonic transducer 52 and is connected to the housing body 61 in a manner that allows it to be attached to or detached from the housing body 61.

[0050] The ultrasonic transducer 52 generates ultrasonic vibrations under the control of the control device 3. In this embodiment 1, the ultrasonic transducer 52 is composed of a BLT (bolt-fastened LANZI-type transducer).

[0051] [Structure of the control device]

[0052] Control device 3 via cable C ( Figure 1 This is used to control the overall operation of the treatment device 2.

[0053] Specifically, the control device 3 detects the treatment operation performed by an operator, such as a surgeon, on the operation button 8 via cable C. Furthermore, upon detecting this treatment operation, the control device 3 applies treatment energy to the object portion held between the clamp member 11 and the treatment section 121 via cable C. That is, the control device 3 performs treatment on the object portion.

[0054] For example, when applying ultrasonic energy to a target area, the control device 3 supplies drive power to the ultrasonic transducer 52 via cable C. As a result, the ultrasonic transducer 52 generates longitudinal vibration (ultrasonic vibration) in the direction along the central axis Ax. Furthermore, the processing unit 121 vibrates with a desired amplitude under the action of this longitudinal vibration. Moreover, ultrasonic vibration is applied from the processing unit 121 to the target area held between the clamping member 11 and the processing unit 121. In other words, ultrasonic energy is applied to the target area from the processing unit 121.

[0055] Furthermore, for example, when applying high-frequency energy to the target area, the control device 3 supplies high-frequency power between the clamping member 11 and the vibration transmission member 12 via the cable C. This allows a high-frequency current to be supplied to the target area held between the clamping member 11 and the handling unit 121. In other words, high-frequency energy is applied to the target area.

[0056] Furthermore, the control device 3 performs different controls when it detects a processing operation on the first operation button 81 and when it detects a processing operation on the second operation button 82. Here, examples of such control include control that applies only ultrasonic energy to the object part, control that applies only high-frequency energy to the object part, and control that applies both ultrasonic energy and high-frequency energy to the object part.

[0057] [Structure of the operation button]

[0058] Next, the structure of operation button 8 will be explained.

[0059] Figures 2-4 This diagram illustrates the structure of operation button 8. Specifically, Figure 2 This is a cross-sectional view obtained by cutting the first operation button 81 and the housing 6 with the XY plane passing through the first operation button 81. Figure 3 This is a cross-sectional view obtained by cutting the first operation button 81, the second operation button 82 and the housing 6 with the XZ plane passing through the first operation button 81 and the second operation button 82. Figure 4 Is Figure 2 and Figure 3 The position of the IV-IV line shown is obtained by cutting the first operation button 81 and the housing 6 with the YZ plane. In addition, the position of the IV-IV line is through the second rotation axis Rx2.

[0060] First, before explaining the structure of the operation button 8, the structure of the housing 6 will be explained.

[0061] The housing 6 is divided into two parts based on the XZ plane: a portion on the -Y axis and a portion on the +Y axis. That is, the housing 6 has a hollow shape by combining the portion on the -Y axis and the portion on the +Y axis. Hereinafter, for ease of explanation, the portion on the -Y axis will be referred to as the first housing 6A. Figures 2-4 The portion on the +Y axis side is designated as the second housing 6B. Figure 2 , Figure 4 ).

[0062] In the combined state of the first housing 6A and the second housing 6B, as follows: Figure 2 or Figure 3 As shown, a first connecting hole 631 is provided on the side of the front end Ar1. This first connecting hole 631 connects the inside and outside of the housing 6, exposing a portion of the first operating button 81 to the outside. Similarly, as... Figure 3 As shown, a second connecting hole 632 is provided on the side of the front end Ar1 at a position closer to the -Z axis than the first connecting hole 631. The second connecting hole 632 connects the inside and outside of the housing 6, so that a part of the second operation button 82 is exposed to the outside.

[0063] like Figures 2-4 As shown, a first protrusion 651A is provided on the inner surface of the first housing 6A, and the first protrusion 651A protrudes in a straight line toward the +Y axis side. Figures 2-4 As shown, the protruding end of the first protrusion 651A has a first receiving portion 6511 that is recessed in a straight line from the center of the Z-axis toward the Y-axis side. Figure 2 or Figure 3 As shown, the first receiving portion 6511 extends through the first protrusion 651A in the X-axis direction. Furthermore, the bottom surface of the first receiving portion 6511 corresponds to the first surface 6511A of the present invention. Figure 2 , Figure 4 ).

[0064] In addition, such as Figure 2 or Figure 3 As shown, a first element mounting portion 661 is provided on the inner surface of the first housing 6A. The first element mounting portion 661 is located at a position closer to the base end Ar2 than the first protrusion 651A, and protrudes in a straight line toward the +Y axis. The protrusion dimension of the first element mounting portion 661 is set to be larger than the protrusion dimension of the first protrusion 651A.

[0065] In addition, such as Figure 3 As shown, on the inner surface of the first housing 6A, at a position closer to the -Z axis than the first protrusion 651A, there is a second protrusion 652A (including the second storage portion 6521 (including the first surface 6511A)) and a second component mounting portion 662, which are the same as the first protrusion 651A (including the first storage portion 6511 (including the first surface 6511A)) and the first component mounting portion 661, respectively.

[0066] On the other hand, such as Figure 2 or Figure 4 As shown, a first protrusion 651B is provided on the inner surface of the second housing 6B, opposite to the first protrusion 651A, protruding linearly toward the Y-axis side. The center of the protruding end of this first protrusion 651B in the Z-axis direction is opposite to the first surface 6511A, corresponding to the first surface 6511B of the present invention. Figure 2 , Figure 4 ).

[0067] Additionally, on the inner surface of the second housing 6B, a second protrusion (not shown) is provided at a position on the -Z axis side that is the same as the first protrusion 651B (including the first surface 6511B).

[0068] In the housing 6 described above, the surface roughness of the first surface 6511A, 6511B, the bottom surface of the second storage part 6521, and the protruding end of the second protrusion (not shown) provided on the second housing 6B is set to be smaller than the surface roughness of other parts.

[0069] For ease of explanation, the space within the housing 6 (fixed handle 62) that is closer to the front end Ar1 than the pair of first protrusions 651A and 651B will be referred to as the first front end space Sp11. Figure 2 , Figure 3 Furthermore, the space within the housing 6 (fixed handle 62) that is closer to the front end Ar1 than the pair of second protrusions 652A is described as the second front end space Sp12. Figure 3 Furthermore, the space within the housing 6 (fixed handle 62) between the pair of first protrusions 651A, 651B and the first element mounting portion 661 is described as the first base-end side space Sp21. Figure 2 , Figure 3 Furthermore, the space within the housing 6 (fixed handle 62) between the pair of second protrusions 652A and the second element mounting portion 662 is described as the second base-end side space Sp22. Figure 3 Furthermore, the space within the housing 6 (fixed handle 62) surrounded by the first storage section 6511 and the first surface 6511B is described as the first storage space Sp31. Figures 2-4 Furthermore, the space within the housing 6 (fixed handle 62) surrounded by the second storage portion 6521 and the protruding end of the second protrusion (not shown) provided on the second housing 6B is described as the second storage space Sp32. Figure 3 ).

[0070] Here, as Figure 2 or Figure 3 As shown, a first switching element SW1 disposed on a flexible substrate is arranged in the first base-end side space Sp21. This first switching element SW1 corresponds to the switching element of the present invention and is a switching element having a metal dome MD1, which is disposed in the first base-end side space Sp21 with the metal dome MD1 facing the front end side Ar1. Moreover, the first switching element SW1 is corresponding to the treatment operation performed by the operator such as the surgeon by pressing the first operation button 81, and the operation signal corresponding to the treatment operation is output to the control device 3.

[0071] In addition, such as Figure 3As shown, a second switching element SW2 disposed on a flexible substrate is arranged in the second base-end side space Sp22. This second switching element SW2 corresponds to the switching element of the present invention and is a switching element having a metal dome MD2, disposed in the second base-end side space Sp22 with the metal dome MD2 facing the front end side Ar1. Furthermore, the second switching element SW2 is activated by pressing the second operation button 82 in accordance with a procedure performed by an operator such as a surgeon, and an operation signal corresponding to that procedure is output to the control device 3.

[0072] like Figures 2-4 As shown, the first operation button 81 includes a first button body 811, a first connecting part 812, a pair of first abutting parts 813, a first sliding part 814, and a first push-press part 815.

[0073] The first button body 811 is located outside the housing 6 and is the part that receives treatment operations performed by an operator such as a surgeon. The first button body 811 has a shape that extends in an arc shape with a second rotation axis Rx2 as the center. The second rotation axis Rx2 passes through a predetermined position of the first operation button 81 and is along the Z-axis.

[0074] like Figure 2 or Figure 3 As shown, the first connecting part 812 passes through the first communicating hole 631 and is disposed inside and outside the fixed handle 62, and is the part that connects the first button body 811 and the first sliding part 814.

[0075] A pair of first abutting portions 813 correspond to the abutting portions of the present invention. For example... Figure 2 As shown, the pair of first abutting portions 813 are located in the first front end space Sp11, and are portions that protrude from the first connecting portion 812 toward the -Y axis side and the +Y axis side, respectively. Moreover, the pair of first abutting portions 813 have the function of preventing the first operating button 81 from disengaging from the housing 6 by abutting against the inner surface of the housing 6.

[0076] The first sliding portion 814 corresponds to the sliding portion of the present invention. For example... Figure 2 or Figure 3 As shown, the first sliding portion 814 is provided at the end of the first connecting portion 812 on the -X axis side and has a flat plate shape extending along the XY plane. The outer surface of the first sliding portion 814 on the -Y axis side and the outer surface on the +Y axis side have an arc shape centered on the second rotation axis Rx2. That is, the outer surface on the -Y axis side and the outer surface on the +Y axis side are formed as curved surfaces with a predetermined curvature. Furthermore, as... Figures 2-4 As shown, the first sliding part 814 is disposed in the first storage space Sp31. Hereinafter, for ease of explanation, the outer surface on the -Y axis side and the outer surface on the +Y axis side will be referred to as the second surface 8141. Figure 2 , Figure 4 ).

[0077] Here, as Figure 4 As shown, the diameter D1 of the second face 8141 is smaller than the separation dimension D2 between the first faces 6511A and 6511B.

[0078] The first push-press portion 815 corresponds to the push-press portion of the present invention. The first push-press portion 815 is provided at the end of the first sliding portion 814 on the -X axis side and protrudes towards the -X axis side. That is, the first push-press portion 815 is provided at a position adjacent to the first sliding portion 814 on the first switching element SW1 side.

[0079] Here, as Figure 2 As shown, the width dimension D3 (length dimension along the Y-axis) of the protruding end of the first push part 815 is smaller than the separation dimension D2 between the first surfaces 6511A and 6511B.

[0080] In the first operation button 81 described above, the surface roughness of the outer surface of the second side 8141 and the first contact part 813 is set to be smaller than the surface roughness of other parts.

[0081] like Figure 3 As shown, the second operation button 82 includes a second button body 821, a second connecting part 822, a pair of first abutting parts 813, a first sliding part 814 (including a second surface 8141), and a first push-press part 815, which are the same as the first button body 811, the first connecting part 812, the first abutting part 813, the first sliding part 814 (including a second surface 8141), and the first push-press part 815 of the first operation button 81, and a second push-press part 825.

[0082] Here, the second connecting portion 822 passes through the second communicating hole 632, thereby being disposed inside and outside the fixed handle 62. In addition, a pair of second abutting portions 823 are respectively located in the second front end side space Sp12. Furthermore, the second sliding portion 824 is disposed in the second storage space Sp32.

[0083] [Actions of operating the buttons]

[0084] Next, the operation of the operation button 8 corresponding to the treatment operation performed by the surgical operator or other operator will be explained. Figures 5-7 This is a diagram illustrating the action of operating button 8. Specifically, Figures 5-7 Is with Figure 2 The corresponding sectional view.

[0085] Furthermore, the operations of the first operation button 81 and the second operation button 82 corresponding to the handling operation are largely the same. Therefore, for ease of explanation, the operation of the first operation button 81 will be described below.

[0086] In this embodiment, the treatment operation performed by an operator such as a surgeon on the operation button 8 includes two operations: a first treatment operation and a second treatment operation, as shown below. Furthermore, Figures 5-7 These respectively indicate the action of the first operation button 81 corresponding to the second handling operation. Furthermore, Figure 6 This indicates that the first and second processing operations were not performed on the first operation button 81.

[0087] The first treatment procedure is to... Figure 6 The first operation button 81, in the state shown, is pressed in a straight line toward the -X axis. Through this first operation, the first operation button 81 slides on the second surface 8141 on the first surfaces 6511A and 6511B while moving in a straight line toward the -X axis. Furthermore, the first push-button portion 815 presses against the metal dome MD1. That is, the first switching element SW1 outputs an operation signal corresponding to the operation.

[0088] Here, the length dimension of the first surfaces 6511A and 6511B in the X-axis direction is set to be greater than the amount of movement of the first operation button 81 achieved by the first disposal operation.

[0089] Furthermore, after the first procedure described above, when the surgeon or other operator releases their hand from the first operation button 81, under the reaction force of the metal dome MD1, the first operation button 81 is forced towards the +X axis side, restoring its original position. Figure 6 The state shown. Additionally, in Figure 6 In the state shown, the first operation button 81 becomes a pair of first abutting parts 813 abutting against the inner surface of the front end side Ar1 of the housing 6, which is approximately parallel to the YZ plane, thus restricting its movement toward the +X axis.

[0090] The second treatment procedure is to... Figure 6 The first operation button 81, as shown in the diagram, is pressed with its body 811 facing either the -Y-axis or +Y-axis side. Additionally, in... Figure 5 The state of the first operation button 81, which indicates that the second processing operation has been performed by pressing towards the Y-axis side, is in progress. Figure 7 The state of the first operation button 81, which indicates that the second processing operation has been performed by pressing towards the +Y axis side, is in progress.

[0091] Through this second treatment operation, such as Figure 5 or Figure 7As shown, the first operation button 81, with one of the pair of first abutting portions 813 abutting against the inner surface of the front end side Ar1 of the housing 6, which is approximately parallel to the YZ plane, slides on the second surface 8141 on the first surfaces 6511A and 6511B, and rotates around the second rotation axis Rx2. Meanwhile, the first push portion 815 presses down on the metal dome MD1. That is, the first switching element SW1 outputs an operation signal corresponding to the operation.

[0092] Here, in the state where no action is taken on the first operation button 81 ( Figure 6 In both the state of performing a operation on the first operation button 81 and the state of performing a operation on the first operation button 81, at least a portion of the first sliding part 814 is disposed between a pair of first surfaces 6511A and 6511B. Furthermore, the second rotation axis Rx2, which serves as the rotation center of the first operation button 81, is located between the pair of first surfaces 6511A and 6511B.

[0093] Furthermore, after the second procedure described above, when the surgeon or other operator releases their hand from the first operation button 81, under the reaction force of the metal dome MD1, the first operation button 81 is forced towards the +X axis side, restoring its original position. Figure 6 The state shown.

[0094] According to the above-described implementation method, the following effects are achieved.

[0095] In the treatment device 2 of this embodiment, the first operation button 81 is configured such that, in response to user operation, the second surface 8141 of the first sliding portion 814 located between the pair of first surfaces 6511A and 6511B slides on the pair of first surfaces 6511A and 6511B, thereby allowing the first operation button 81 to rotate about the second rotation axis Rx2 as the center. That is, in this embodiment, as a structure capable of performing the second treatment operation, a structure that omits the pin used in conventional structures is provided.

[0096] Therefore, in the processing device 2 of this embodiment, since it is not a conventional structure that utilizes pins, the number of components can be reduced, the structure can be simplified, and the assemblability can be improved.

[0097] Furthermore, in the processing device 2 of this embodiment, the surface roughness of the first surfaces 6511A and 6511B, the bottom surface of the second storage portion 6521, and the protruding end of the second protrusion (not shown) provided on the second housing 6B is set to be smaller than the surface roughness of other parts. Additionally, in the first operation button 81, the surface roughness of the outer surfaces of the second surface 8141 and the first contact portion 813 is set to be smaller than the surface roughness of other parts.

[0098] Therefore, when performing the first and second processing operations on the first operation button 81, setting the sliding resistance between the first operation button 81 and the housing 6 to be relatively low can improve the operability of the first and second processing operations.
