[0021] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] According to an embodiment of the present application, an ablation electrode device with an improved internal structure of a handle is provided, such as Figure 1 and Figure 2As shown, it includes: an outer sleeve 1, an emitter needle 2 and a loop pole needle 3 are arranged inside the outer sleeve 1, and the emitter needle 2 and the loop pole needle 3 extend along the axial direction of the outer sleeve 1 inside the outer sleeve 1, and also includes a handle 4 with a hollow structure connected to the outer sleeve 1. In this embodiment, the two are detachably connected. In other embodiments, the two can also be fixedly connected; a first wire 5 is electrically connected to the emitter needle 2, which is used to provide an ablation signal for the emitter 22; a second wire 6 is electrically connected to the loop pole needle 3, which is used to provide a loop signal for the loop pole 32. When performing an ablation operation, the first wire 5 and the second wire 6 are both electrically connected to the ablation host (not shown in the figure); a storage box 7 is also provided in the hollow structure of the handle 4. In this embodiment, the storage box 7 is detachably connected to the handle 4. In other embodiments, the storage box 7 can also be directly fixed in the handle 4. This application does not make specific limitations. A baffle 71 is provided in the storage box 7 , and a first storage groove 72 and a second storage groove 73 are formed separately in the storage box 7 through the baffle 71 . Preferably, the baffle 71 and the storage box 7 are integrally formed. In order to transmit the ablation signal to the emitter 22 through the emitter needle 2, it is necessary to electrically connect the emitter needle 2 to the first wire 5, so one end of the emitter needle 2 is fixedly connected to one end of the first wire 5 to form a first connector 25, and the first connector 25 is arranged in the first receiving groove 72; in addition, in order to transmit the loop signal to the loop pole 32 through the loop pole needle 3, it is necessary to electrically connect the loop pole needle 3 to the second wire 6, so one end of the loop pole needle 3 is fixedly connected to one end of the second wire 6 to form a second connector 36, and the second connector 36 is arranged in the second receiving groove 73. Because the first receiving groove 72 and the second receiving groove 73 are separated by the baffle 71, and the first baffle 71 is made of insulating material, the first connector 25 and the second connector 36 are effectively separated in the storage box 7 to avoid short circuit between the two, thereby avoiding short circuit between the emitter 22 and the loop pole 32. It should be noted that, in this embodiment, the first joint 25 and the second joint 36 are connected together by welding. In other embodiments, other connection methods may also be used.

[0024] In this embodiment, the emitter 22 is provided at the end of the emitter needle 2 away from the handle 4 and is electrically connected to the emitter needle 2 , and the return electrode 32 is provided at the end of the return electrode needle 3 away from the handle 4 and is electrically connected to the return electrode needle 3 .

[0025] In some optional embodiments, such as Figure 3As shown, at the first joint 25, one end of the emitter pin 2 is fixedly connected to one end of the first wire 5 via a first metal connecting sleeve 251; at the second joint 36, one end of the return pin 3 is fixedly connected to one end of the second wire 6 via a second metal connecting sleeve 361. To achieve a better connection, the emitter pin 2 at the first joint 25 is welded to the first wire 5, and the return pin 3 at the second joint 36 is welded to the second wire 6. The provision of the first metal connecting sleeve 251 and the second metal connecting sleeve 361 strengthens the connection between the emitter pin 2 and the first wire 5, and between the return pin 3 and the second wire 6, and improves the electrical connection. The first connecting sleeve 251 is disposed in the first receiving slot 72, and the second connecting sleeve 361 is disposed in the second receiving slot 73, with a baffle 71 between them. The provision of the baffle 71 simply and effectively isolates the first joint 25 and the second joint 36.

[0026] In some alternative embodiments, continue as Figure 1 and Figure 2 As shown, a portion of the emitter needle 2 is encased in a first insulating tube 21, and a portion of the return electrode needle 3 is encased in a second insulating tube 31. That is, except for the two ends of the emitter needle 2, which need to be exposed, the rest of the emitter needle 2 is encased in the first insulating tube 21. Similarly, except for the two ends of the return electrode needle 3, the rest of the return electrode needle 3 is encased in the second insulating tube 31. Furthermore, a double-lumen tube 8 is encased outside the first and second insulating tubes 21 and 31. This double-lumen tube 8 has two lumens. The portion of the emitter needle 2, together with the first insulating tube 21 outside it, is disposed in one lumen of the double-lumen tube 8, while the portion of the return electrode needle 3, together with the second insulating tube 31 outside it, is disposed in the other lumen of the double-lumen tube 8. The double-lumen tube 8, together with the emitter needle 2 and return electrode needle 3 it encases, extends within the outer sleeve 1 and extends from the end of the outer sleeve 1 away from the handle 4. One end of the double-lumen tube 8 is disposed within the storage box 7. An outer sleeve assembly 11 is disposed over the end of the outer sleeve 1 located within the handle 4 and the adjacent portion of the double-lumen tube 8. One end of the outer sleeve assembly 11 abuts against the inner wall of one end of the handle 4. The provision of the outer sleeve assembly 11 can prevent liquids, impurities, etc. from entering the handle 4, further preventing the occurrence of short circuits.

[0027] In some optional embodiments, the first wire 5 except for the portion near the first connector 25 and the second wire 6 except for the portion near the second connector 36 are wrapped together with a sheath 9, one end of the sheath 9 is fixed in the storage box 7, and the rest of the sheath 9 extends from the first end surface 76 of the storage box 7 away from the outer sleeve 1.

[0028] In some optional embodiments, the baffle 71 extends in a direction parallel to the axial direction of the outer sleeve 1, and the baffle 71 is integrally formed with the storage box 7. The baffle 71 and the storage box 7 are made of insulating plastic, which is simple to manufacture and low in cost. A protrusion 791 extending along the length of the storage box 7 is provided on the lower side 79 of the bottom surface of the storage box 7, and a groove (not shown) extending along the length of the handle 4 is provided on the inner side surface of the handle 4. The protrusion 791 is embedded in the groove. This facilitates the quick positioning of the storage box 7 in the correct position within the handle 4 during assembly and allows the storage box 7 to be easily fixed within the handle 4.

[0029] In one possible implementation, Figure 4 and Figure 5 As shown, this embodiment is Figure 1 、 Figure 2 The primary difference between the illustrated embodiments is that the storage box 7 of the ablation electrode device is filled with insulating curing adhesive 10. This curing adhesive 10 encapsulates and secures the first connector 25 and the second connector 36 within the storage box 7, further strengthening the connection between the emitter needle 2 and the first wire 5, and the connection between the return electrode needle 3 and the second wire 6. Because the curing adhesive 10 has solidified the connection, it prevents the emitter needle 2 from disconnecting from the first wire 5, or the return electrode needle 3 from disconnecting from the second wire 6, due to external forces. Furthermore, the insulation isolation between the first connector 25 and the second connector 36 is improved. The first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 within the storage box 7 are also encapsulated and secured within the storage box 7 by the curing adhesive 10. This further secures these components within the storage box 7 and prevents liquids, impurities, and the like from entering the first connector 25 or the second connector 36, potentially causing short circuits. It should be noted that the curing glue 10 can be UV glue, sealant or other easy-to-curing glue. Some curing glue 10 is transparent or translucent. Figure 4 、 Figure 5In the figure, the curing glue 10 is drawn in shaded form in order to more clearly show the content of this part of the invention, and is not used to limit the present invention. In other embodiments, the curing glue 10 can also be replaced with other insulating filling materials, which can seal and fix the first connector 25, the second connector 36 and other components located in the storage box 7 in the storage box 7. It should be noted that when the ablation electrode device is assembled, the first connector 25, the second connector 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 are first placed in the storage box 7 that has not been filled with the curing glue 10. The first connector 25 is arranged in the first receiving groove 72, and the second connector 36 is arranged in the second receiving groove 73. The two are insulated and isolated by the baffle 71. Subsequently, the curing glue 10 is poured into the groove of the storage box 7, and the curing glue 10 covers the first joint 25, the second joint 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9. After the curing glue 10 is cured, the storage box 7 forms an approximately closed structure, and the first joint 25, the second joint 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 are sealed and fixed in the storage box 7.

[0030] In some optional embodiments, only the first connector 25 and the second connector 36 located in the storage box 7 can be encapsulated and fixed with the curing glue 10, and the curing glue 10 is not provided on part of the first insulating tube 21, part of the second insulating tube 31, the double-lumen tube 8, part of the first wire 5, part of the second wire 6 and the sheath 9 located in the storage box 7. This application does not make specific limitations, and mainly ensures that the first connector 25 and the second connector 36 are encapsulated and fixed in the storage box 7 by the curing glue 10.

[0031] In some optional embodiments, only the first connector 25 and the second connector 36 can be set in the storage box 7, or the first connector 25, the second connector 36 and one or more components of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 can be set in the storage box 7. This application does not make specific limitations, and mainly ensures that the first connector 25 and the second connector 36 are set in the storage box 7.

[0032] In another possible embodiment, Figure 6 and Figure 7 As shown, this embodiment is Figure 1 、 Figure 2 The main difference between the ablation electrode device with an improved internal structure of the handle in the embodiment shown is the different structure of the storage box 7 in the ablation electrode device. Figure 6 and Figure 7The figures are respectively schematic diagrams of the overall structure and the split structure of the storage box 7 in this embodiment. The storage box 7 in this embodiment includes a accommodating chamber 74 and a lid 75 that are snapped together. The baffle 71 is disposed on the upper side 78 of the bottom surface of the accommodating chamber 74, and the upper side 78 faces the lid 75. In other words, the first receiving groove 72 and the second receiving groove 73 are formed within the accommodating chamber 74, and the first connector 25 and the second connector 36 are respectively disposed within the first receiving groove 72 and the second receiving groove 73 within the accommodating chamber 74. Preferably, a protrusion 791 extending along the length of the storage box 7 is provided on the lower side 79 of the bottom surface of the accommodating chamber 74, with the lower side 79 facing away from the lid 75. At the same time, a groove (not shown) extending along the length of the handle 4 is provided on the inner side of the handle 4, into which the protrusion 791 can be inserted. Therefore, by embedding the protrusion 791 in the groove, the storage box 7 can be firmly fixed within the handle 4. Firstly, it is convenient to quickly locate the storage box 7 to the correct position in the handle 4 during assembly, and secondly, it is convenient to fix the storage box 7 in the handle 4.

[0033] In this embodiment, the first wire 5, excluding the portion near the first connector 25, and the second wire 6, excluding the portion near the second connector 36, are wrapped together in a sheath 9. One end of the sheath 9 is secured within the storage box 7, while the remainder of the sheath 9 extends from a first end face 76 of the storage box 7, away from the outer sleeve 1. In other words, after the accommodating chamber 74 and the lid 75 are snapped together, a first through-hole 761 is formed in the first end face 76 of the storage box 7, through which the sheath 9 extends to the outside of the storage box 7. Furthermore, portions of the first insulating tube 21, the second insulating tube 31, the dual-lumen tube 8, the first wire 5, and the second wire 6 are also disposed within the storage box 7. It should be noted that when assembling the ablation electrode device, the first connector 25, the second connector 36, and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 are first placed in the accommodating cavity 74. The first connector 25 is arranged in the first receiving groove 72, and the second connector 36 is arranged in the second receiving groove 73. The two are insulated and isolated by the baffle 71. Subsequently, the cover 75 is snapped onto the accommodating cavity 74, so that the first connector 25, the second connector 36, and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 are fixed in the storage box 7, and the double-lumen tube 8 extends out of the storage box 7 from the second through hole 771 on the second end surface 77 of the storage box 7.

[0034] In some optional embodiments, only the first connector 25 and the second connector 36 can be set in the storage box 7, or the first connector 25, the second connector 36 and one or more components of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 can be set in the storage box 7. This application does not make specific limitations, and mainly ensures that the first connector 25 and the second connector 36 are set in the storage box 7.

[0035] Due to the setting of the storage box 7, the first connector 25 and the second connector 36 are simply and effectively isolated and insulated. At the same time, the storage box 7 is connected by a snap-on method. After the first connector 25, the second connector 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 are placed in the accommodating cavity 74, the cover 75 can be easily snapped onto the accommodating cavity 74. Storing these components in the storage box 7 can, firstly, avoid a short circuit between the first connector 25 and the second connector 36, secondly, avoid the first connector 25 and the second connector 36 being easily pulled and disconnected, and thirdly, the assembly of the handle 4 of the ablation electrode device is more convenient and quick. The first connector 25 and the second connector 36 can be placed on both sides of the baffle 71 in the storage box 7 to achieve insulation, without the need for more complicated insulation treatment with the help of other components and processes.

[0036] In another possible embodiment, Figure 8 As shown, this embodiment is Figure 6 The main differences in the embodiments shown are

[0037] The storage box 7 is filled with insulating curing glue 10, and the first connector 25 and the second connector 36 are encapsulated and fixed in the storage box 7 by the curing glue 10, so that the connection between the emitter needle 2 and the first wire 5 and the connection between the loop pole needle 3 and the second wire 6 are more secure. Because they have been solidified by the curing glue 10, they can better prevent the emitter needle 2 from being disconnected from the first wire 5 or the loop pole needle 3 from being disconnected from the second wire 6 due to external forces. The first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, and the second wire 6 located in the storage box 7 are also encapsulated and fixed in the storage box 7 by the curing glue 10. These components are more firmly fixed in the storage box 7, and the curing glue 10 can further prevent liquids, impurities, etc. from entering the first connector 25 or the second connector 36 and causing short circuits. It should be noted that the curing glue 10 can be UV glue, sealant or other easy-to-cure glue. Some curing glues 10 are transparent or translucent. Figure 8In the figure, the curing glue 10 is drawn in shaded form in order to more clearly show the content of this part of the invention, and is not used to limit the present invention. In other embodiments, the curing glue 10 can also be replaced with other insulating filling materials, which can seal and fix the first connector 25, the second connector 36 and other components located in the storage box 7 in the storage box 7. It should be noted that when the ablation electrode device is assembled, the first connector 25, the second connector 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 are first placed in the accommodating cavity 74 of the storage box 7 that has not yet been filled with the curing glue 10. The first connector 25 is arranged in the first receiving groove 72, and the second connector 36 is arranged in the second receiving groove 73. The two are insulated and isolated by the baffle 71. Subsequently, the cover 75 is snapped onto the accommodating cavity 74, and finally, the curing glue 10 is poured into the groove of the storage box 7 from the opening 751 on the cover 75. The curing glue 10 covers the first connector 25, the second connector 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, and the second wire 6. After the curing glue 10 is cured, the storage box 7 forms an approximately closed structure, and the first connector 25, the second connector 36 and part of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, and the second wire 6 are encapsulated and fixed in the storage box 7.

[0038] In some optional embodiments, only the first connector 25 and the second connector 36 located in the storage box 7 may be encapsulated and fixed with the curing glue 10, and the curing glue 10 may not be provided on part of the first insulating tube 21, part of the second insulating tube 31, the double-lumen tube 8, part of the first wire 5, and part of the second wire located in the storage box 7. This application does not make specific restrictions, and the main purpose is to ensure that the first connector 25 and the second connector 36 are encapsulated and fixed in the storage box 7 by the curing glue 10. In some optional embodiments, only the first connector 25 and the second connector 36 may be provided in the storage box 7, or the first connector 25, the second connector 36 and one or more of the first insulating tube 21, the second insulating tube 31, the double-lumen tube 8, the first wire 5, the second wire 6, and the sheath 9 may be provided in the storage box 7. This application does not make specific restrictions, and the main purpose is to ensure that the first connector 25 and the second connector 36 are provided in the storage box 7.
