For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0011] 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.

[0012] The present application is further described in detail below in conjunction with the accompanying drawings.

[0013] According to an embodiment of the present application, an ablation electrode device with an optimized internal structure of a handle is provided, such as Figure 1 , Figure 2As shown, it includes: an emitter needle 1, a loop transistor 2 sleeved outside the emitter needle 1, a handle 3 with a hollow structure connected to the loop transistor 2, a first wire 4 electrically connected to the emitter needle 1, and a second wire 5 electrically connected to the loop transistor 2. A storage box 6 is arranged in the hollow structure of the handle 3. The emitter needle 1 and the first wire 4 are fixedly connected in the storage box 6 to form a first joint 14, that is, the first joint 14 is arranged in the storage box 6, and the proximal end of the loop transistor 2 is also arranged in the storage box 6. A first insulating layer 11 is sleeved on part of the emitter needle 1, and a second insulating layer 21 is sleeved on part of the loop transistor 2. That is, except for the two ends that need to be exposed on the emitter needle 1, the rest of the parts are sleeved with the first insulating layer 11. Similarly, except for the two ends that need to be exposed on the loop transistor 2, the rest of the parts are sleeved with the second insulating layer 21. In this embodiment, the emitter needle 1 and the first wire 4 are fixedly connected together by welding, and the first joint 14 formed by the two is arranged in the storage box 6, which can prevent the emitter needle 1 from being disconnected from the first wire 4 due to external pulling. In other embodiments, the emitter needle 1 and the first wire 4 can also be electrically connected together by other connection methods, which is not limited in this application.

[0014] In some optional embodiments, a first opening 611 is provided on the first side 61 of the storage box 6, the first opening 611 penetrates the first side 61, and a conductive buckle 51 is connected to one end of the second wire 5, the buckle 51 is snapped into the first opening 611 and contacts the return pole tube 2, thereby realizing the electrical connection between the return pole tube 2 and the second wire 5. Because the buckle 51 is directly connected to the second wire 5 and the two are electrically connected, when assembling the handle 3 of the ablation electrode device with optimized internal structure of the handle, the buckle 51 can be directly snapped into the first opening 611 to contact the return pole tube 2, thereby realizing the electrical connection between the return pole tube 2 and the second wire 5 conveniently and quickly.

[0015] In some optional embodiments, the buckle 51 is an elastic metal buckle 51, and a hook 511 is also provided on the buckle 51. A second opening 612 is also provided on the first side 61 of the storage box 6. In this embodiment, the second opening 612 passes through the first side 61, and the hook 511 is inserted into the second opening 612 from the inner side of the first side 61, so that the buckle 51 is more firmly connected to the first opening 611, ensuring that the buckle 51 and the return pole tube 2 are always in contact. The inner side is the side close to the return pole tube 2. In other embodiments, the second opening 612 may not pass through the first side 61, but a groove is dug from the inner side of the first side 61, and the groove does not pass through the outer side of the first side 61, and the hook 511 is inserted into the groove from the inner side of the first side 61. The outer side is the side away from the return pole tube 2.

[0016] In this embodiment, the distal end of the loop electrode tube 2 is used as the loop electrode 23, and the first wire 4 and the second wire 5 are both electrically connected to the ablation host (not shown in the figure), and the ablation host provides a loop signal to the loop electrode 23 through the second wire 5 and the loop electrode tube 2. In addition, an insulating seat 9 is fixedly installed at the end of the loop electrode 23, and the emitter 12 is fixedly installed on the insulating seat 9. The emitter 12 is electrically connected to the distal end of the emitter needle 1, and the ablation host provides an ablation signal to the emitter 12 through the first wire 4 and the emitter needle 1. In other embodiments, the emitter 12 and the loop electrode 23 can also be designed as other forms of structures, which are not specifically limited in this application.

[0017] In some optional embodiments, a hollow protrusion 31 extending along the length direction of the handle 3 is provided on the inner side surface of the distal end of the handle 3, and a sleeve 22 is provided on the outer surface of the partial loop pole tube 2, and the sleeve 22 is composed of a first part 221 and a second part 222 with different outer diameters, and the outer diameter of the first part 221 is larger than the outer diameter of the second part 222, and one end of the first part 221 is fixedly connected to the second end surface 63 of the distal end of the storage box 6. The second part 222 is arranged in the hollow channel 311 of the protrusion 31 and abuts against the inner side surface of the distal end of the handle 3. It should be noted that abutting means that the second part 222 and the inner side surface of the distal end of the handle 3 can be directly in contact, or close but not in contact. In addition, the outer diameter of the first part 221 is larger than the diameter of the hollow channel 311, so the first part 221 rests on the end surface of the proximal end of the protrusion 31, so that the position of the loop pole tube 2 relative to the handle 3 is fixed.

[0018] In some optional embodiments, a sheath 45 is wrapped around the outside of the first wire 4 except for the portion near the first connector 14 and the second wire 5 except for the portion connected to the buckle 51, one end of the sheath 45 is fixed in the storage box 6, and the rest of the sheath 45 extends from the first end surface 62 at the proximal end of the storage box 6.

[0019] In a possible implementation, Figure 3 As shown, this embodiment is Figure 1 The main difference of the ablation electrode device of the embodiment shown is that a gasket 2221 is disposed outside the second part 222, the outer diameter of the gasket 2221 is larger than the diameter of the hollow channel 311, and the gasket 2221 is squeezed between the protrusion 31 and the first part 221. The gasket 2221 can effectively prevent liquid from flowing into the handle 3 and causing a short circuit.

[0020] In a possible implementation, Figure 4 and Figure 5 As shown, this embodiment is Figure 1 , Figure 2The main difference of the embodiment shown is that the storage box 6 in the ablation electrode device is filled with insulating curing glue 7, and the first connector 14 is encapsulated and fixed in the storage box 6 by the curing glue 7, so that the connection between the emitter needle 1 and the first wire 4 is more secure, because it has been cured by the curing glue 7, so it can prevent the emitter needle 1 from being disconnected from the first wire 4 due to external pulling. The return pole tube 2, the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45 in the storage box 6 are also encapsulated and fixed in the storage box 6 by the curing glue 7. These components are more firmly fixed in the storage box 6, and the curing glue 7 can prevent liquids, impurities, etc. from entering the storage box 6 to cause a short circuit. In addition, the second wire 5 extending from the buckle 51 in contact with the return pole tube 2 in the storage box 6 first extends outside the storage box 6, then extends into the storage box 6, and finally extends from the first end surface 62 at the proximal end of the storage box 6. It should be noted that the curing glue 7 can be UV glue, sealant or other easily curable glue. Some curing glue 7 is transparent or translucent. Figure 4 , Figure 5 In the figure, the curing glue 7 is drawn in the form of a shadow 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 7 can also be replaced with other insulating filling materials, so that the first connector 14 and other components located in the storage box 6 can be sealed and fixed in the storage box 6. It should be noted that when the ablation electrode device is assembled, the first connector 14, the proximal end of the return pole tube 2, and part of the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45 are first placed in the storage box 6 that has not been filled with the curing glue 7, and then the curing glue 7 is poured into the storage box 6. The curing glue 7 covers the first connector 14, the proximal end of the return pole tube 2, and part of the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45. After the curing treatment of the curing glue 7, the first connector 14, the proximal end of the return pole tube 2, and part of the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45 are sealed and fixed in the storage box 6.

[0021] In some optional embodiments, only the first connector 14, the proximal end of the loop pole tube 2, part of the first insulating layer 11, and part of the first wire 4 may be arranged in the storage box 6, and the second wire 5 and the sheath 45 are arranged outside the storage box 6, and this application does not make specific limitations.

[0022] In another possible implementation, if Figure 6 , Figure 7 As shown, this embodiment is Figure 1 , Figure 2 The main difference between the ablation electrode device with optimized internal structure of the handle in the illustrated embodiment is that the structure of the storage box 6 in the ablation electrode device is different. Figure 6 , Figure 7The schematic diagrams are respectively the overall structure diagram and the split structure diagram of the storage box 6 in this embodiment. The storage box 6 in this embodiment includes a first shell 64 and a second shell 65 which are connected by a buckle 51. The first connector 14, the proximal end of the return pole tube 2 and part of the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45 are all arranged in the first shell 64, and the second shell 65 covers the first shell 64. In addition, the second wire 5 extending from the buckle 51 in contact with the return pole tube 2 in the storage box 6 first extends outside the storage box 6, then extends into the storage box 6 from an opening 651 on the second shell 65, and finally extends from the first end face 62 of the proximal end of the storage box 6. A through first opening 611 is set on the first side surface 61 of the first shell 64, and part of the second wire 5 together with the buckle 51 pass through the opening 651 on the second shell 65 and the buckle 51 is clamped in the first opening 611 at the junction with the return pole tube 2. A second opening 612 is provided on the first side surface 61 of the first housing 64, and the hook 511 is inserted into the second opening 612. In this embodiment, the first housing 64 and the second housing 65 are buckled together by the cooperation of the groove and the protrusion. In other embodiments, other methods can also be used to make the two detachably fit together.

[0023] The first connector 14, the proximal end of the loop pole tube 2 and part of the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45 are all arranged in the storage box 6 by snapping the first shell 64 and the second shell 65 together, so as to better prevent the first connector 14 from being disconnected due to external force.

[0024] In some optional embodiments, only the first connector 14, the proximal end of the loop pole tube 2, part of the first insulating layer 11, and part of the first wire 4 may be arranged in the storage box 6, and the second wire 5 and the sheath 45 are arranged outside the storage box 6, and this application does not make specific limitations.

[0025] In some optional embodiments, see Figure 6 , Figure 7 as well as Figure 8 ( Figure 8 for Figure 7(Schematic diagram of the structure in which the first shell 64 of the middle storage box 6 is arranged in the ablation electrode device for optimizing the internal structure of the handle) A baffle 641 is arranged in the first shell 64, and the baffle 641 is arranged on the upper side surface of the bottom surface of the first shell 64, and the upper side surface faces the second shell 65. The baffle 641 separates the first shell 64 into a first groove 642 and a second groove 643, and the first connector 14 is arranged in the first groove 642, and the second groove 643 is used to arrange the suction tube 8, and the suction tube 8 is used to suck out physiological saline. It should be noted that the first connector 14 can also be arranged in the second groove 643, and the suction tube 8 can be arranged in the first groove 642. The first connector 14 and the suction tube 8 are separated by the baffle 641, and the two do not affect each other, and it is convenient to operate when assembling at the handle 3 of the ablation device. In addition, a third groove 644 is provided in the first shell 64 , and the proximal end of the loop pole tube 2 passes through the second end surface 63 of the storage box 6 opposite to the first end surface 62 and is provided in the third groove 644 , so that the loop pole tube 2 is more stable in the first shell 64 .

[0026] It should be noted that, in other embodiments, the baffle 641 may not be provided in the first housing 64. This application does not make any specific limitation.

[0027] In another possible implementation, if Fig. 9 As shown, this embodiment is Figure 6 , Figure 8 The main difference of the illustrated embodiment is that the storage box 6 is filled with insulating curing glue 7, and the first connector 14 is encapsulated and fixed in the storage box 6 by the curing glue 7, so that the connection between the emitter needle 1 and the first wire 4 is more secure, because it has been solidified by the curing glue 7, which can better prevent the emitter needle 1 from being disconnected from the first wire 4 due to external pulling or the like. The proximal end of the loop transistor 2 located in the storage box 6 and part of the first insulating layer 11, the first wire 4, the second wire 5, the sheath 45, and the suction tube 8 are also encapsulated and fixed in the storage box 6. These components are more firmly fixed in the storage box 6, and the curing glue 7 can further prevent liquids, impurities, etc. from entering the first connector 14 and causing a short circuit. It should be noted that the curing glue 7 can be a UV glue, a sealant, or other easily curable glue. Some curing glues 7 are transparent or translucent. Fig. 9In the figure, the curing glue 7 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 7 can also be replaced with other insulating filling materials, which can seal and fix the first connector 14 and other components located in the storage box 6 in the storage box 6. It should be noted that when the ablation electrode device is assembled, the first connector 14, the proximal end of the return pole tube 2, and part of the first insulating layer 11, the first wire 4, the second wire 5, the sheath 45, and the suction tube 8 are first placed in the first shell 64 of the storage box 6 that has not been filled with the curing glue 7. The first connector 14 is arranged in the first groove 642, the suction tube 8 is arranged in the second groove 643, and the proximal end of the return pole tube 2 is arranged in the third groove 644. The second shell 65 is placed on the first shell 64, and part of the second wire 5 together with the buckle 51 are first passed through an opening 651 on the second shell 65 and the buckle 51 is clamped. The buckle 51 is snapped into the first opening 611 on the first shell 64, and then the second shell 65 is snapped onto the first shell 64. Finally, the curing glue 7 is poured into the storage box 6 from the opening 651 on the second shell 65. The curing glue 7 covers the first joint 14, the proximal end of the loop pole tube 2 and part of the first insulating layer 11, the first wire 4, the second wire 5, the sheath 45, and the suction tube 8. After the curing glue 7 is cured, the first joint 14, the proximal end of the loop pole tube 2 and part of the first insulating layer 11, the first wire 4, the second wire 5, the sheath 45, and the suction tube 8 are encapsulated and fixed in the storage box 6.

[0028] In some optional embodiments, only the first connector 14, the proximal end of the loop pole tube 2, part of the first insulating layer 11, and part of the first wire 4 may be arranged in the storage box 6, and the second wire 5 and the sheath 45 are arranged outside the storage box 6, and this application does not make specific limitations.

[0029] It should be noted that in order to more clearly illustrate the present invention with the accompanying drawings, Figure 4-Figure 7 , Fig. 9 The first connector 14, the loop electrode 2, the first insulating layer 11, the first wire 4, the second wire 5, the sheath 45 and the suction tube 8 arranged in the storage box 6 are not drawn. These drawings mainly show the structure of the storage box 6 in an ablation electrode device with an optimized internal structure of the handle, but are not used to limit the present invention.

[0030] In another possible implementation, if Fig.10 As shown, this embodiment is Figure 1The main difference of the embodiment shown is that one end of the emitter needle 1 is fixedly connected to one end of the first wire 4 at the first joint 14 through a metal connecting sleeve 141. In order to achieve a better connection effect, the emitter needle 1 at the first joint 14 is welded to the first wire 4 in this embodiment. By providing the metal connecting sleeve 141, the connection between the emitter needle 1 and the first wire 4 is more secure, and the electrical connection is better.
