[First Embodiment]
A first embodiment of the present invention will be described with reference to the drawings. The therapeutic treatment apparatus according to the present embodiment is an apparatus for use in treatment of living tissue. This therapeutic treatment apparatus causes high-frequency energy and thermal energy to act on a living tissue. An outline of the appearance of the therapeutic treatment apparatus 300 is shown in FIG. As shown in this figure, the therapeutic treatment apparatus 300 includes an energy treatment tool 310, a control device 370, and a foot switch 380.

  The energy treatment tool 310 is a linear type surgical treatment tool for performing treatment by, for example, penetrating the abdominal wall. The energy treatment device 310 includes a handle 350, a shaft 340 attached to the handle 350, and a holding unit 320 provided at the tip of the shaft 340. The holding unit 320 can be opened and closed, and is a treatment unit that holds a living tissue to be treated and performs treatment such as coagulation and incision of the living tissue. Hereinafter, for the sake of explanation, the holding portion 320 side is referred to as a distal end side, and the handle 350 side is referred to as a proximal end side. The handle 350 includes a plurality of operation knobs 352 for operating the holding unit 320. The handle 350 is provided with a non-volatile memory (not shown) that stores eigenvalues and the like related to the energy treatment tool 310. The shape of the energy treatment device 310 shown here is, of course, an example, and other shapes may be used as long as they have the same function. For example, the shape may be a forceps or the shaft may be curved.

  The handle 350 is connected to the control device 370 via the cable 360. Here, the cable 360 and the control device 370 are connected by a connector 365, and this connection is detachable. That is, the therapeutic treatment apparatus 300 is configured such that the energy treatment tool 310 can be exchanged for each treatment. A foot switch 380 is connected to the control device 370. The foot switch 380 operated with a foot may be replaced with a switch operated with a hand or other switches. When the operator operates the pedal of the foot switch 380, ON / OFF of the supply of energy from the control device 370 to the energy treatment tool 310 is switched.

  An example of the structure of the holding part 320 and the shaft 340 is shown in FIG. 2A shows a state in which the holding unit 320 is closed, and FIG. 2B shows a state in which the holding unit 320 is opened. The shaft 340 includes a cylindrical body 342 and a sheath 343. The cylindrical body 342 is fixed to the handle 350 at its proximal end. The sheath 343 is disposed on the outer periphery of the cylindrical body 342 so as to be slidable along the axial direction of the cylindrical body 342.

  A holding part 320 is disposed at the tip of the cylindrical body 342. The holding unit 320 includes a first holding member 322 and a second holding member 324. The base portion of the first holding member 322 is fixed to the distal end portion of the cylindrical body 342 of the shaft 340. On the other hand, the base portion of the second holding member 324 is rotatably supported by the support pin 346 at the distal end portion of the cylindrical body 342 of the shaft 340. Therefore, the second holding member 324 rotates around the axis of the support pin 346 and opens or closes with respect to the first holding member 322.

  In a state in which the holding part 320 is closed, the cross-sectional shape of the base part of the first holding member 322 and the base part of the second holding member 324 is circular. The second holding member 324 is biased by an elastic member 347 such as a leaf spring so as to open with respect to the first holding member 322. When the sheath 343 is slid to the distal end side with respect to the cylindrical body 342 and the base portion of the first holding member 322 and the base portion of the second holding member 324 are covered by the sheath 343, as shown in FIG. The first holding member 322 and the second holding member 324 are closed against the urging force of the elastic member 347. On the other hand, when the sheath 343 is slid to the proximal end side of the cylindrical body 342, the second holding member 324 is moved relative to the first holding member 322 by the urging force of the elastic member 347 as shown in FIG. open.

  The cylindrical body 342 includes a first high-frequency electrode energization line 162 connected to a first high-frequency electrode 110, which will be described later, and a second high-frequency electrode energization line 262 connected to the second high-frequency electrode 210. It is inserted. Further, the cylindrical body 342 includes a pair of first heater energization lines 164 connected to an electrothermal conversion element 130 which is a heat generating member (described later) disposed on the first high-frequency electrode 110, and a second high-frequency electrode 210. A pair of second heater energization lines 264 connected to the electrothermal conversion elements 230 disposed in the are inserted.

  A drive rod 344 connected to one of the operation knobs 352 on the base end side is installed inside the cylinder 342 so as to be movable along the axial direction of the cylinder 342. On the distal end side of the drive rod 344, a thin plate-like cutter 345 having a blade formed on the distal end side is installed. When the operation knob 352 is operated, the cutter 345 is moved along the axial direction of the cylindrical body 342 via the drive rod 344. When the cutter 345 moves to the distal end side, the cutter 345 is accommodated in a first cutter guide groove 332 and a second cutter guide groove 334 described later formed in the holding portion 320.

  An outline of the configuration of the first holding member 322 is shown in FIG. As shown in this figure, the first holding member 322 is formed with a first cutter guide groove 332 for guiding the cutter 345 described above. The first holding member 322 is provided with a first high-frequency electrode 110 formed of, for example, a copper thin plate. The first high-frequency electrode 110 is configured to come into contact with a living tissue on one main surface (hereinafter referred to as a first main surface). Since the first high-frequency electrode 110 has the first cutter guide groove 332, the planar shape thereof is a U-shape as shown in FIG. The first high-frequency electrode 110 is electrically connected to a first high-frequency electrode conducting line 162 as will be described in detail later. The first high-frequency electrode 110 is connected to the control device 370 via the first high-frequency electrode energization line 162 and the cable 360. In addition, an electrothermal conversion element 130 and a cover member 150 are disposed on the second main surface of the first high-frequency electrode 110 that does not contact the living tissue, as will be described in detail later. Thus, the 1st electrode part 100 which consists of the 1st high frequency electrode 110, the electrothermal conversion element 130, the cover member 150 grade | etc., Is formed. The first electrode unit 100 is embedded and fixed in the first holding member main body 326. A configuration example of the first electrode unit 100 will be described in detail later.

  As shown in FIG. 2, the second holding member 324 has a shape that is symmetric to the first holding member 322 and has the same structure as the first holding member 322. That is, a second cutter guide groove 334 is formed in the second holding member 324 at a position facing the first cutter guide groove 332. Further, the second holding member 324 is provided with a second high-frequency electrode 210 at a position facing the first high-frequency electrode 110. The second high-frequency electrode 210 is configured to come into contact with the living tissue on one main surface thereof. The second high-frequency electrode 210 is connected to the control device 370 via the second high-frequency electrode energization line 262 and the cable 360.

  In addition, the electrothermal conversion element 230 and the cover member 250 are disposed on the surface of the second high-frequency electrode 210 that does not come into contact with the living tissue. In this way, the second electrode unit 200 including the second high-frequency electrode 210, the electrothermal conversion element 230, the cover member 250, and the like is formed. The second electrode unit 200 is embedded and fixed in the second holding member main body 328.

  The first electrode unit 100 will be described in detail. The second electrode unit 200 has the same structure as that of the first electrode unit 100, and thus the description of the second electrode unit 200 is omitted. An exploded perspective view of the first electrode unit 100 is shown in FIG. As shown in this figure, the first electrode unit 100 includes a first high-frequency electrode 110, a high heat conduction heat resistant adhesive sheet 120, an electrothermal conversion element 130, a heat resistant adhesive sheet 140, and a cover member 150. The first high-frequency electrode 110, the high heat conduction heat-resistant adhesive sheet 120, the electrothermal conversion element 130, the heat-resistant adhesive sheet 140, and the cover member 150 are U-shaped. The first high-frequency electrode 110 is made of, for example, copper as described above, and the thickness thereof is, for example, about 0.5 mm.

  A plan view of the electrothermal conversion element 130 is shown in FIG. As shown in this figure, the electrothermal conversion element 130 includes, for example, a polyimide substrate 132. The shape of the substrate 132 is the same as that of the first high-frequency electrode 110 on the tip side, and is slightly longer than the first high-frequency electrode 110. In FIG. 5, a position corresponding to an end portion on the proximal end side of the first high-frequency electrode 110 when the first electrode portion 100 is assembled is indicated by a two-dot broken line. A portion protruding from the first high-frequency electrode 110 is referred to as a protruding portion 133.

  An electric resistance pattern 134 is formed in most of the region excluding the protruding portion 133 of the substrate 132 by a stainless (SUS) pattern, for example. First lead connection portions 136 connected to both ends of the electric resistance pattern 134 are formed by SUS patterns at the end portions including the protruding portion 133 of the substrate 132. When the voltage is applied to the pair of first lead connection portions 136, the electrical resistance pattern 134 generates heat. Thus, the electrothermal conversion element 130 functions as a seat heater.

  Furthermore, a second lead connection portion 138 that is insulated from the electrical resistance pattern 134 and the first lead connection portion 136 is formed by an SUS pattern at an end portion including the protruding portion 133 of the substrate 132. The second lead connection portion 138 is a connection portion for connecting the first high-frequency electrode energization line 162 for applying a voltage to the first high-frequency electrode 110. The distal end side of the second lead connection portion 138 is formed up to a position overlapping the first high-frequency electrode 110. The second lead connecting portion 138 does not need to be formed on each of the two projecting portions 133, and only one second connecting portion 138 may be formed on either one. However, the second lead connecting portion 138 may be formed on each of the two protruding portions 133. Note that the thickness of the substrate 132 is, for example, 100 μm, and the thickness of the SUS pattern is, for example, 20 μm.

  The first high-frequency electrode 110 and the electrothermal conversion element 130 are bonded together by a high heat conductive heat-resistant adhesive sheet 120. The high heat conductive heat resistant adhesive sheet 120 is a sheet having high heat conductivity, withstanding high temperatures, and having adhesiveness. The high heat conductive heat resistant adhesive sheet 120 is formed, for example, by mixing an epoxy resin and a ceramic having high heat conductivity such as alumina or aluminum nitride. The high heat conduction heat resistant adhesive sheet 120 has high adhesion performance, good heat conductivity, and electrical insulation. The thickness of the high heat conductive heat resistant adhesive sheet 120 is, for example, 60 μm.

  The shape of the high heat conductive heat resistant adhesive sheet 120 is shown in FIG. In this figure, when the first electrode unit 100 is assembled, a position corresponding to the end portion on the base end side of the first high-frequency electrode 110 is indicated by a two-dot broken line. The high heat conductive heat resistant adhesive sheet 120 has substantially the same shape as the first high frequency electrode 110. However, the high heat conductive heat-resistant adhesive sheet 120 is provided with a short-circuit prevention portion 122 that protrudes toward the base end side from the first high-frequency electrode 110 at a portion corresponding to the first lead connection portion 136 of the electrothermal conversion element 130. Yes. The short-circuit prevention unit 122 ensures electrical insulation between the first high-frequency electrode 110 and the first lead connection unit 136. Further, the high heat conductive heat resistant adhesive sheet 120 is shorter than the first high frequency electrode 110 at a portion corresponding to the second lead connecting portion 138. In a portion where the high heat conductive heat resistant adhesive sheet 120 is shorter than the first high frequency electrode 110, the first high frequency electrode 110 and the second lead connection portion are applied by applying a conductive paste as will be described later. The electrical conductivity between 138 and 138 is ensured.

  The cover member 150 is made of heat-resistant resin. The cover member 150 has a thickness of about 0.3 mm, for example. The cover member 150 is bonded to the electrothermal conversion element 130 by the heat resistant adhesive sheet 140. The heat resistant adhesive sheet 140 is an adhesive sheet having high heat resistance. The heat resistant adhesive sheet 140 is made of, for example, an epoxy or polyimide material. The thickness of the heat resistant adhesive sheet 140 is, for example, about 50 μm. The heat-resistant adhesive sheet 140 and the cover member 150 have substantially the same shape as the first high-frequency electrode 110.

  In the configuration of the first electrode unit 100, the thickness of the first high-frequency electrode 110 is relatively thick compared to other members. This is to increase the thermal conductivity of the first high-frequency electrode 110 so that the temperature of the first high-frequency electrode 110 can be made uniform even when the living tissue partially contacts the first high-frequency electrode 110. is there. This is important in temperature management in the case of anastomosing / joining living tissues with the energy treatment device 310 according to the present embodiment.

  A manufacturing process of the first electrode unit 100 will be described. First, the first high-frequency electrode 110, the high heat conductive heat-resistant adhesive sheet 120, and the electrothermal conversion element 130 are overlapped and joined by hot pressing. The electrothermal conversion element 130 is overlaid with the surface on which the electric resistance pattern 134 and the like are formed facing the first high-frequency electrode 110 side.

  FIG. 7 is a perspective view showing an outline after joining. The electrical resistance pattern 134 of the electrothermal conversion element 130 is arranged on the first high frequency electrode 110 side of the electrothermal conversion element 130 with respect to the first high frequency electrode 110 via the high thermal conductive heat resistant adhesive sheet 120. ing. Therefore, the electrical resistance pattern 134 is thermally coupled to the first high-frequency electrode 110 via the high thermal conductive heat resistant adhesive sheet 120. Since only the high heat conductive heat-resistant adhesive sheet 120 exists between the electric resistance pattern 134 and the first high-frequency electrode 110, the heat generated in the electric resistance pattern 134 is efficiently transferred to the first high-frequency electrode 110. The

  As shown in FIG. 7, the short-circuit prevention portion 122 of the high heat conductive heat resistant adhesive sheet 120 protrudes from the first high-frequency electrode 110. Therefore, the electrical resistance pattern 134 of the electrothermal conversion element 130 and the first lead connection portion 136 connected thereto are reliably insulated from the first high-frequency electrode 110. On the other hand, the high heat conductive heat resistant adhesive sheet 120 does not exist at the end of the second lead connection portion 138. Therefore, the second lead connection portion 138 and the first high-frequency electrode 110 can be easily short-circuited.

  After the first high-frequency electrode 110 and the electrothermal conversion element 130 are joined, the heat-resistant adhesive sheet 140 and the cover member 150 are superimposed on the polyimide substrate 132 of the electrothermal conversion element 130, and hot pressing is performed. Be joined. FIG. 8 is a perspective view showing an outline after joining.

  Subsequently, as shown in FIG. 9, the conductive paste 124 is disposed between the second lead connection portion 138 and the first high-frequency electrode 110. As a result, the second lead connection portion 138 and the first high-frequency electrode 110 are electrically connected. Note that instead of the connection using the conductive paste 124, for example, a connection by welding or soldering may be used.

  Next, as shown in FIG. 10, the pair of first heater energization lines 164 is connected to the pair of first lead connection portions 136 by, for example, welding. In addition, the first high-frequency electrode energization line 162 is connected to the second lead connection portion 138 by, for example, soldering. Subsequently, as shown in FIG. 11, a sealing agent 170 made of silicone resin or the like is applied to the entire region where the first high-frequency electrode energization line 162 and the first heater energization line 164 are connected. .

  A cross section of the proximal end portion of the first electrode unit 100 is shown in FIGS. FIG. 12 is a cross-sectional view passing through the first heater energization line 164 and the first lead connection portion 136, and FIG. 13 passes through the first high-frequency electrode energization line 162 and the second lead connection portion 138. It is sectional drawing. As shown in FIGS. 12 and 13, in the first electrode unit 100 according to this embodiment, the electrothermal conversion element 130 in which the first lead connection unit 136 and the second lead connection unit 138 are formed is the first electrode unit 100. The first high-frequency electrode 110 and the cover member 150 are provided so as to protrude. Furthermore, the first lead connection portion 136 and the second lead connection portion 138 are arranged on the first high-frequency electrode 110 side of the substrate 132. Here, the first high-frequency electrode 110 is relatively thick in the configuration of the first electrode unit 100. As shown in FIG. 12, the first heater energization line 164 is connected to the first lead connection portion 136 so as to extend from the electrothermal conversion element 130. Further, as shown in FIG. 13, the first high-frequency electrode energization line 162 is connected to the second lead connection portion 138 so as to extend from the electrothermal conversion element 130. Therefore, according to the present embodiment, the first heater energization line 164 and the first high-frequency electrode energization line 162 do not contribute to the thickness of the first electrode unit 100, and the first electrode unit 100 thickness reduction (low profile) is realized.

  In order to efficiently transmit the heat generated in the electrothermal conversion element 130 to the first high-frequency electrode 110, the cover member 150 and the surrounding first holding member body 326 include the first high-frequency electrode 110 and the high heat conduction heat-resistant adhesive sheet. It is preferable to have a thermal conductivity lower than 120. Since the thermal conductivity of the cover member 150 and the first holding member main body 326 is low, the heat loss generated in the electrothermal conversion element 130 is reduced. Although the first electrode unit 100 has been described above, the second electrode unit 200 has the same structure as the first electrode unit 100.

  Next, the operation of the medical treatment apparatus 300 according to this embodiment will be described. The surgeon operates the input unit of the control device 370 in advance to set the output conditions of the therapeutic treatment device 300, for example, the set power of the high frequency energy output, the target temperature of the heat energy output, the heating time, and the like. In the therapeutic treatment apparatus 300, each value may be set individually, or a set of setting values corresponding to the surgical procedure may be selected.

  The holding part 320 and the shaft 340 of the energy treatment tool 310 are inserted into the abdominal cavity through the abdominal wall, for example. The operator operates the operation knob 352 to open and close the holding unit 320, and grasps the living tissue to be treated by the first holding member 322 and the second holding member 324. At this time, the first main surface of both the first high-frequency electrode 110 provided on the first holding member 322 and the second high-frequency electrode 210 provided on the second holding member 324 is subjected to treatment. Living tissue comes into contact.

  When the operator grasps the biological tissue to be treated by the holding unit 320, the operator operates the foot switch 380. When the foot switch 380 is switched to ON, the first high-frequency electrode 110 and the second high-frequency electrode 210 are preset from the control device 370 via the first high-frequency electrode energization line 162 passing through the cable 360. High frequency power is supplied. The supplied power is, for example, about 20W to 80W. As a result, the living tissue generates heat and the tissue is cauterized. By this cauterization, the tissue is denatured and solidified.

  Next, after stopping the output of the high-frequency energy, the control device 370 supplies power to the electrothermal conversion element 130 so that the temperature of the first high-frequency electrode 110 becomes the target temperature. Here, the target temperature is 200 ° C., for example. At this time, the current flows from the control device 370 through the electric resistance pattern 134 of the electrothermal conversion element 130 via the cable 360 and the first heater energization line 164. The electrical resistance pattern 134 generates heat due to current. The heat generated in the electrical resistance pattern 134 is transmitted to the first high-frequency electrode 110 through the high heat conductive heat resistant adhesive sheet 120. As a result, the temperature of the first high-frequency electrode 110 increases.

  Similarly, electric power is supplied to the electrothermal conversion element 230 so that the temperature of the second high-frequency electrode 210 becomes the target temperature. Electric power is supplied from the control device 370 to the electrothermal conversion element 230 of the second electrode unit 200 via the cable 360 and the second heater energization line 264, and the temperature of the second high-frequency electrode 210 rises.

  The biological tissue in contact with the first high-frequency electrode 110 or the second high-frequency electrode 210 is further cauterized and further solidified by these heats. When the living tissue is solidified by heating, the output of thermal energy is stopped. Finally, the operator operates the operation knob 352 to move the cutter 345 and cut the living tissue. The treatment of the living tissue is thus completed.

  Thus, for example, the first high-frequency electrode 110 contacts the living tissue on the first main surface of the first main surface and the second main surface forming the front and back surfaces and transfers heat to the living tissue. Functions as a heat transfer plate. For example, the substrate 132 is provided on the second main surface side of the heat transfer plate and functions as a substrate having a protruding portion protruding from the heat transfer plate. For example, the electrical resistance pattern 134 is thermally coupled to the heat transfer plate and functions as an electrical resistance pattern formed on the substrate that generates heat when a voltage is applied. For example, the first lead connection portion 136 is formed on the protruding portion of the substrate and functions as a first lead connection portion electrically connected to the electrical resistance pattern. For example, the first heater energization line 164 is disposed closer to the heat transfer plate than the substrate, and is electrically connected to the first lead connection portion to supply power to the electrical resistance pattern. Functions as a lead wire. For example, the second lead connection portion 138 is formed on the protruding portion of the substrate, is electrically insulated from the first lead connection portion, and is electrically connected to the heat transfer portion. It functions as a part. For example, the first high-frequency electrode energization line 162 is disposed closer to the heat transfer plate than the substrate, is electrically connected to the second lead connection portion, and applies a high-frequency voltage to the heat transfer plate. It functions as a second lead wire. For example, the high heat conductive heat-resistant adhesive sheet 120 is disposed between the heat transfer plate and the electric resistance pattern, and functions as an adhesive sheet that bears thermal connection between the electric resistance pattern and the heat transfer plate.

According to the present embodiment, since the wiring for supplying power to the first high-frequency electrode 110 and the like is performed on the polyimide substrate 132 extended from the first high-frequency electrode 110, the first electrode unit 100 is provided. Thinning (low profile) is realized. The same applies to the second electrode unit 200.
As a result, the holding part 320 of the energy treatment device 310 can be reduced in size.

[Second Embodiment]

The electrothermal conversion element 730 and the heat transfer plate 710 are bonded by the adhesive sheet 732 by being hot-pressed with a large load. Further, the cover member is bonded to the surface on which the electrical resistance pattern 734 is formed using a heat-resistant adhesive sheet, as in the first embodiment. Thereafter, as shown in FIG. 15D, the first heater energization line 164 is connected to the lead connection portion 736 through the opening 732 a and sealed with the sealant 770. Thus, for example, the adhesive sheet 732 is responsible for thermal coupling between the electric resistance pattern and the heat transfer plate, and functions as an adhesive sheet positioned between the heat transfer plate and the electric resistance pattern.

  Also according to the present embodiment, the heat transfer section 600 can be reduced in height as in the first embodiment, and as a result, the holding section 320 of the energy treatment device 310 can be reduced in size. Moreover, according to this embodiment, since the high heat conductive heat-resistant adhesive sheet 120 in the first embodiment is not used, the number of parts and the manufacturing process can be reduced as compared with the first embodiment. Furthermore, cost reduction can be realized by reducing the number of parts and the manufacturing process.

  In addition, unlike the second embodiment, in this embodiment, the electrical resistance pattern 734 and the like are insulated from the heat transfer plate 710 by the adhesive sheet 732. Therefore, when the heat transfer plate 710 is made of, for example, a copper electrode, a configuration in which a high-frequency voltage can be applied to the living tissue can be taken as in the first embodiment.
