Description

Technical Field

[0001] This invention relates to an electrode unit for blocking or modulating nerves in the body and an electrode device including the same. Background Technology

[0002] Nerve block surgery refers to procedures that control an abnormally overactive autonomic nervous system by damaging specific nerves. For example, renal nerve block surgery can treat hypertension and heart disease by damaging the renal sympathetic nerves that lead to the kidneys, while pulmonary nerve block surgery can treat lung diseases by damaging the parasympathetic nerves that lead to the lungs.

[0003] Nerves are typically surrounded by the outer walls of tubes such as blood vessels and bronchi. Therefore, it may be necessary to measure nerve signals by looking through the outer walls of such tubes, or to damage or destroy nerves by transmitting electrical stimulation or various forms of energy to them.

[0004] For example, when performing surgery on the renal arteries, the main renal artery, which is typically 5mm to 7mm in diameter, can be used, or the accessory renal artery, which is typically 1mm to 2mm in diameter. Furthermore, the size of the arteries containing nerves varies from person to person and also depends on their location.

[0005] When performing this surgery, it is particularly important to precisely position the assembly, which includes an electrode formed at the end of the catheter, around the outer wall of the catheter for precise positioning. Specifically, in order to effectively block or adjust the nerve, it is necessary to surround the outer wall of the catheter on which the nerve is distributed along the peripheral direction, and it is necessary to reliably and quickly place the assembly with the electrode formed in the middle of the catheter in an enclosed state. At the same time, it is necessary to perform this while suppressing or minimizing unnecessary energy transfer and contact within the body. Prior art literature includes Korean Patent Publication No. 2013-0108401 (published on October 2, 2013). Summary of the Invention

[0012] In one embodiment of the present invention, the fixing layer is attached to the electrode layer, and at least a portion of the electrode portion of the electrode layer is not attached to the fixing layer.

[0013] In one embodiment of the present invention, the first fastening portion of the fixing layer is attached to the fastening portion of the electrode layer, and the entire connecting portion of the fixing layer is attached to the extension portion of the electrode layer and a portion of the electrode portion of the electrode layer.

[0014] In one embodiment of the present invention, the first fastening portion of the fixing layer is attached to the fastening portion of the electrode layer, a portion of the connecting portion of the fixing layer is attached to the entire extension of the electrode layer, and the remaining portion of the connecting portion of the fixing layer is not attached to the electrode portion of the electrode layer.

[0015] In one embodiment of the present invention, the first fastening portion of the fixing layer is attached to the fastening portion of the electrode layer in a corresponding manner, a portion of the connecting portion of the fixing layer is attached to the extension portion of the electrode layer and a portion of the electrode portion of the electrode layer in a mounting manner, and the remaining portion of the connecting portion of the fixing layer is not attached to the electrode portion of the electrode layer.

[0016] In one embodiment of the present invention, a sensor unit is further included, disposed on the electrode unit of the electrode layer to detect temperature.

[0017] Another embodiment of the present invention provides an electrode device for blocking or adjusting nerves in the body, comprising: an electrode unit according to an embodiment of the present invention described above; and an electrode conductor, which, by being deformed into a coiled state, brings the electrode unit into contact with the tubular tissue. The electrode conductor includes: a main body portion formed to be spaced apart from the electrode unit and surrounding the outer periphery of the tubular tissue in the coiled state; and a connecting portion formed to be connected to the end portion of the main body portion to fix the fastening portion of the electrode unit.

[0018] In another embodiment of the present invention, the aforementioned connecting portion includes: a first clamping member formed to be fixed to the aforementioned main body portion; and a second clamping member connected to the aforementioned first clamping member via the aforementioned fastening portion of the aforementioned electrode unit.

[0019] In another embodiment of the present invention, either the first clamping member or the second clamping member has a protrusion formed along one direction.

[0023] The solutions described above for solving the problem are merely exemplary and should not be construed as limiting the invention. In addition to the exemplary embodiments described above, there may be additional embodiments, as illustrated in the accompanying drawings and detailed description.

[0024] Invention Effects

[0025] According to any of the solutions to the problem described above, in the wound state, the electrode conductor and the electrode unit can be arranged to be spaced apart from each other in most of the space. Therefore, surgery can be performed with the space between the electrode unit and the electrode conductor exposed to air or the like, and the heat generated from the electrode unit can be easily dissipated through convective heat transfer.

[0026] Furthermore, according to any of the solutions to the problem presented in this invention, not only can the connection (assembly) point between the electrode unit and the electrode conductor be minimized, but the electrode unit can also be firmly supported by the connection portion of the electrode conductor, thereby ensuring durability and reliability. Furthermore, the electrode unit and electrode conductor described above can be easily assembled.

[0027] Furthermore, since the electrode conductors, which are dynamically deformed into a coiled state, and the electrode units, which are closely attached to the tubes within the body, are configured individually, the effects caused by power transmission, such as vibration or force transmission to the tubes within the body, can be suppressed.

[0049] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0050] Figure 1 This is a side view of an electrode device 100 according to an embodiment of the present invention. Figure 2 This is a perspective view showing the wound state of the electrode conductor 130 according to an embodiment of the present invention. Additionally, Figures 3a to 3c This is a diagram illustrating the process by which the electrode conductor 130 is deformed into a wound state according to an embodiment of the present invention. Figure 4 This is a perspective view showing the main body 131 and the connecting portion 132 of the electrode conductor 130 according to an embodiment of the present invention.

[0051] First, refer to Figure 1 According to an embodiment of the present invention, the electrode device 100 may include: a main body 110, an electrode unit 120, and an electrode conductor 130.

[0052] The main body 110 may include: a shaft 111 extending in one direction; a gripping portion 112 configured to connect to the shaft 111 for the surgeon to grip; a guiding operation portion 113 formed in the gripping portion 112 and capable of operating the movement of the electrode conductor 130; and an electrode operation portion 114 formed in the gripping portion 112 and capable of operating the energy transfer of the electrode unit 120. Elements for driving and controlling the electrode unit 120 and the electrode conductor 130 may be disposed inside the main body 110.

[0053] Electrode unit 120 and electrode conductor 130 protrude from one end of shaft 111 and are configured to surround and block or adjust at least a portion of nerves distributed in tubular tissues within the body, depending on the surgeon's operation.

[0054] For example, such as Figure 2 As shown, electrode unit 120 can contact the outer surface of tubular tissue V in the body by surrounding it, thereby transmitting electrical stimulation or various energies to nerves distributed in tissue V to block or modulate at least a portion of the nerves.

[0055] At this time, the electrode conductor 130 can perform the function of contacting the electrode unit 120 with the tubular tissue V. The electrode conductor 130 is combined with the electrode unit 120 and can be deformed into a wound state to contact the electrode unit 120 with the tubular tissue V. The wound state can be, for example, as shown in the figure below. Figure 2 and Figure 3c The state shown.

[0056] Reference Figures 3a to 3c as well as Figure 4In order to achieve deformation in the wound state, the electrode conductor 130 provided by the present invention may include a main body portion 131 and a connecting portion 132. The main body portion 131 may be configured to surround the outer periphery of the tubular tissue V through the electrode unit 120 in the wound state.

[0057] According to one embodiment of the present invention, the electrode conductor 130 can be housed together with the electrode unit 120 inside the shaft 111 and deformed into a coiled state as it is pulled out from one end forward F for surgical purposes.

[0058] like Figures 3a to 3c As shown, multiple main body portions 131 can be pulled out sequentially and moved to one side, thereby forming a wound state that surrounds the tubular tissue V as a whole. However, in the wound state, the electrode conductor 130 is separated from the outer peripheral surface of the tubular tissue V, and the electrode unit 120 disposed on the inner side of the wound electrode conductor 130 can be in close contact with the outer peripheral surface of the tubular tissue V.

[0059] According to one embodiment of the present invention, the main body 131 may include a first main body group 131x and a second main body group 131y. For example... Figures 3a to 4 As shown, the first main body group 131x may have a first length in the long side direction, and the second main body group 131y may have a second length longer than the first length. As an example, the first main body group 131x and the second main body group 131y may each include joints with different lengths, for example, 6 joints.

[0060] Based on the length difference between the first main body group 131x and the second main body group 131y, in the winding state, the first main body group 131x can form a first radius of curvature, and the second main body group 131y can form a second radius of curvature larger than the first radius of curvature. That is, as... Figure 3c As shown, a joint with a relatively short length (first body group 131x) can form a small radius of curvature, while a joint with a longer length (second body group 131y) can form a large radius of curvature.

[0061] Specifically, the first main body group 131x forming the first radius of curvature can be disposed on the side near the joint 132, while the second main body group 131y forming the second radius of curvature can be disposed on the side near the shaft 111.

[0062] In the wound state, when the main body portion 131 located near the joint portion 132 forms a smaller radius of curvature, such as Figure 3c As shown, a path for the junction 132 to enter can be formed in the space between the tubular tissue V and the shaft 111. The electrode conductor 130, including the main body 131, can generally have a helical shape.

[0063] on the other hand, Figure 5This is a top view showing a portion of an electrode unit 120 according to an embodiment of the present invention. Figures 6a to 6b This is an exploded perspective view of an electrode unit 120 according to an embodiment of the present invention. Figure 7 This is an exploded perspective view of the electrode unit 120 and the connecting portion 132 according to an embodiment of the present invention. Figure 8 This is a perspective view of the electrode unit 120 and the connecting portion 132 being joined together according to an embodiment of the present invention.

[0064] According to one embodiment of the present invention, the electrode unit 120 is an electrode device disposed for blocking or modulating nerves in the body, such as an electrode unit surrounding tubular tissue in the body. Figure 5 As shown, it can be formed by sequentially extending the fastening part 1201, the extension part 1202 and the electrode part 1203.

[0065] Fastening part 1201 can be formed to allow passage Figures 7 to 8 The through hole 120a used to connect the fastening part 1201 and the connecting part 132 is described.

[0066] The electrode unit 120 can be configured such that when it surrounds a tubular tissue within the body, the electrode portion 1203 contacts and surrounds the outer surface of the tubular tissue. The electrode unit 120 can be composed of a flexible circuit board (PCB) for transmitting high-frequency energy, a transducer for transmitting ultrasonic energy, or a metal electrode for transmitting high-voltage energy, so that energy can be transmitted when the electrode portion 1203 surrounds the outer surface of the tubular tissue.

[0067] The electrode portion 1203 of this electrode unit 120 can be formed with an electrode 122 capable of transferring energy to the tubular tissue. The electrode 122 can be composed of a pair of electrodes extending parallel to each other on the electrode portion 1203, i.e., a bipolar structure.

[0068] Electrode 122 can be made of a harmless and conductive material, such as stainless steel or gold, to block or denervate or control or modulate nerves. Furthermore, electrode 122 can transmit various types of energy generated from an energy source generator.

[0069] For example, radio-frequency (RF) energy, electrical energy, laser energy, ultrasonic energy, high-intensity focused ultrasonic energy, cryogenic energy, and other thermal energy can be used.

[0070] Furthermore, a sensor section 123 may be disposed on the electrode section 1203 between the electrodes 122. The sensor section 123 may be a thermocouple composed of a first metal 123a and a second metal 123b. As an example, the sensor section 123 may be composed of a pair of copper and constantan. When performing nerve resection surgery using the electrode device 100 according to an embodiment of the present invention, the sensor section 123 may monitor the temperature of the surgical site or measure the signal of the tissue V nerve.

[0071] Additionally, as shown in FIG6, an electrode unit 120 according to an embodiment of the present invention may include an electrode layer 121 and a fixing layer 126 stacked with the electrode layer 121.

[0072] The electrode layer fastening portion 1211, the electrode layer extension portion 1212, and the electrode portion 1213 can be extended sequentially to form the electrode layer 121.

[0073] In addition, the fixing layer 126 can be stacked on the electrode layer 121 for the fastening portion 1211, the extension portion 1212 and a portion of the electrode portion 1213 of the electrode layer 121.

[0074] The fixing layer 126 may be provided with a first fastening part 1261 formed at one end, a second fastening part 1263 formed at the other end, and a connecting part 1262 connecting the first and second fastening parts 1261 and 1263.

[0075] The first fastening part 1261 of the fixing layer corresponds to the fastening part 1211 of the electrode layer, and the fastening part 1201 of the electrode unit can be formed by stacking the fastening part 1211 of the electrode layer.

[0076] The connecting portion 1262 of the fixing layer can extend to a portion of the extension 1212 of the electrode layer 121 and a portion of the electrode portion 1213. In this case, a portion of the connecting portion 1262 of the fixing layer corresponds to the extension 1212 of the electrode layer, and the extension 1202 of the electrode unit can be formed by stacking it on the extension 1212 of the electrode layer. Furthermore, the remaining portion of the connecting portion 1262 of the fixing layer can be stacked on the electrode portion 1213 of the electrode layer.

[0077] like Figure 6b As shown, the boundary between the connecting portion 1262 of the fixing layer and the second fastening portion 1263 can be configured such that the second fastening portion 1263 and the connecting portion 1262 of the fixing layer are bent.

[0078] The following will refer to Figures 7 to 8 The combination of the electrode conductor and the electrode unit 120 will be explained.

[0079] In the electrode conductor, the connecting portion 132 can be configured to connect to the end of the main body portion, thereby fixing the end of the electrode unit 120. For example... Figure 7 As shown, the connecting portion 132 may include a first clamping member 132a and a second clamping member 132b. Additionally, it may include a connector wire 133 that passes through the main body and is connected to the second clamping member 132b to guide the main body into a wound state.

[0080] The connector wire 133 can be formed to pass through the main body in sequence. The connector wire 133 can guide the electrode conductor to deform into a tube shape surrounding the body.

[0081] The second clamping member 132b may include: a wire groove 132b2 for inserting the end of the connector wire 133; and a fixing plate 132b3 that closes a portion of the wire groove 132b2 to prevent the end of the connector wire 133 from detaching from the wire groove 132b2.

[0082] The wire groove 132b2 can be configured to receive the end of the connector wire 133 between a plurality of fastening grooves 132b1 provided in the second clamping member 132b. The diameter of the end of the connector wire 133 inserted into the wire groove 132b2 is larger than the diameter of the connector wire 133 or the shape is different from that of the connector wire 133, so that it can be locked in place by the fixing plate 132b3 and fixed in the wire groove 132b2 without detachment.

[0083] In addition, the first clamping member 132a can be fixed to the main body, and the second clamping member 132b can be connected to the first clamping member 132a through a part of the electrode unit 120, preferably through the fastening part 1201 of the electrode unit and the second fastening part 1263 of the fixing layer.

[0084] Careful observation of the connection structure between the first clamping member 132a and the second clamping member 132b reveals that, according to an embodiment of the present invention, either the first clamping member 132a or the second clamping member 132b may have a protrusion 132a1 formed protruding in one direction, while the other of the first clamping member 132a and the second clamping member 132b may have a fastening groove 132b1 formed recessed corresponding to the protrusion 132a1.

[0085] For example, when the first clamping member 132a has a protrusion 132a1, the second clamping member 132b may have a fastening groove 132b1; conversely, when the second clamping member 132b has a protrusion, the second clamping member 132b may have a fastening groove.

[0086] The protrusion 132a1 provided on the first clamping member 132a can pass through the second fastening part of the fixing layer and the fastening part of the electrode unit 120 and engage with the fastening groove 132b1 provided on the second clamping member 132b. At this time, through holes 120a and 1263a through which the protrusion 132a1 can pass can be formed in the fastening part 1201 of the electrode unit and the second fastening part 1263 of the fixing layer, respectively.

[0087] When the first clamping member 132a and the second clamping member 132b are clamped between the first clamping member 132a and the second clamping member 132b, and the first clamping member 132a and the second clamping member 132b are fastened, as follows: Figure 8 As shown, the electrode unit 120 can be securely fixed while surrounding the second clamping member 132b. Specifically, the fastening portion, extension portion, and part of the electrode portion of the electrode layer, as well as the fixing layer, can surround the second clamping member 132b.

[0088] Figures 9a to 9b This is a side view showing the attachment state of the electrode layer 121 and the fixing layer 126 of an electrode unit according to an embodiment of the present invention. Figures 10a to 10b They are shown separately in Figures 9a to 9b The diagram shows the state in which the electrode conductor 130 and the electrode unit 120 surround the tubular tissue V in the attached state.

[0089] In Figure 9, the front end (left end) of the joint 132 coincides with the boundary between the extension of the electrode unit and the electrode portion. Considering this, it can be seen that... Figure 9a The region denoted as S corresponds to the fastening part, extension part, and part of the electrode part of the electrode unit, and also corresponds to the first fastening part and connecting part of the fixing layer. Furthermore, it can be seen that... Figure 9b The region denoted as S corresponds to the fastening and extension of the electrode unit, and also corresponds to part of the first fastening and connecting part of the fixing layer.

[0090] According to one embodiment of the present invention, the fixing layer 126 can be attached to the electrode layer 121 in a state of being stacked on the electrode layer 121.

[0091] For example, for Figure 9a In the region denoted as S, the fixing layer 126 can be attached to the electrode layer 121. That is, the first fastening portion and the entire connecting portion of the fixing layer 126 can be attached to the electrode layer 121. Thus, the first fastening portion of the fixing layer 126 can be attached correspondingly to the fastening portion of the electrode layer 121, and the entire connecting portion of the fixing layer 126 can be attached to the extension portion and a portion of the electrode portion of the electrode layer 121 in a mounting manner.

[0092] In this attachment state, such as Figure 10aAs shown, the electrode conductor 130 and the electrode unit 120 can surround the tubular tissue V. At this time, the electrode conductor 130 is deformed into a wound state that brings the electrode unit 120 into contact with the tubular tissue V, and can be arranged to surround the outer periphery of the tissue V with the electrode unit 120 in between. With a portion of the electrode portion of the electrode unit 120 in contact with the first section of the connecting portion 132, i.e., the second clamping member, the electrode unit 120 contacts the outer surface of the tissue V and can surround the tissue V.

[0093] Alternatively, the fixing layer 126 may be attached to the electrode layer 121, but for at least a portion of the electrode portion of the electrode layer 121, the fixing layer 126 and the electrode layer 121 may not be attached.

[0094] For example, for Figure 9b In the region denoted as S, the fixing layer 126 can be attached to the electrode layer 121. Specifically, a portion of the first fastening portion and a part of the connecting portion of the fixing layer 126 can be attached to the electrode layer 121. Thus, the first fastening portion of the fixing layer 126 can be attached correspondingly to the fastening portion of the electrode layer 121, and a part of the connecting portion of the fixing layer 126 can be attached to the entire extension of the electrode layer 121. Furthermore, the remaining portion of the connecting portion of the fixing layer 126 may not be attached to the electrode layer 121, particularly the electrode portion of the electrode layer 121.

[0095] In this attachment state, such as Figure 10b As shown, the electrode conductor 130 and the electrode unit 120 can surround the tubular tissue V. In this case, a portion of the electrode portion of the electrode unit 120 does not contact the first section of the joint 132, i.e., the second clamping member. Therefore, the electrode unit can form a smaller radius of curvature compared to... Figure 9a The attachment state can surround tubular tissue V with a smaller diameter.

[0096] Alternatively, although not shown, the first fastening portion of the fixing layer is attached to the fastening portion of the electrode layer in a corresponding manner, a portion of the connecting portion of the fixing layer is attached to the extension portion of the electrode layer and a portion of the electrode portion of the aforementioned electrode layer in a mounting manner, and the remaining portion of the connecting portion of the fixing layer may not be attached to the electrode portion of the electrode layer.

[0097] In this attachment state, the electrode unit can form a ratio of Figure 9a The electrode unit in the attached state shown has a smaller radius of curvature than the electrode unit in the attached state, and can form a radius of curvature smaller than the electrode unit in the attached state. Figure 9b The electrode unit in the attached state shown has a large radius of curvature.

[0098] The above description of the present invention is for illustrative purposes only. Those skilled in the art will understand that it can be easily modified into other specific embodiments without altering the technical concept or essential features of the invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not limiting. For example, components described as a single type may be implemented in a distributed manner; similarly, components described as distributed may be implemented in a combined manner.

[0099] The scope of this invention is defined by the following claims rather than the detailed description above, and all modifications or alterations to the embodiments derived from the meaning and scope of the claims and their equivalents should be understood to be included within the scope of this invention.
