In addition, the technical features of the different embodiments of the present application described below may be combined with each other as long as they do not collide with each other.
The application is described in further detail below with reference to the accompanying drawings.
According to the embodiment of the application, as shown in fig. 1 and 2, the ablation electrode device for optimizing the internal structure of the handle is provided, and comprises an emitter sub-needle 1, a loop electrode tube 2 sleeved outside the emitter sub-needle 1, a handle 3 with a hollow structure and connected with the loop electrode tube 2, a first lead 4 electrically connected with the emitter sub-needle 1, a second lead 5 electrically connected with the loop electrode tube 2, a storage box 6 arranged in the hollow structure of the handle 3, the emitter sub-needle 1 and the first lead 4 are fixedly connected in the storage box 6 and form a first joint 14, namely the first joint 14 is arranged in the storage box 6, the proximal end of the loop electrode tube 2 is also arranged in the storage box 6, a part of the emitter sub-needle 1 is sleeved with a first insulating layer 11, a part of the loop electrode tube 2 is sleeved with a second insulating layer 21, namely the emitter sub-needle 1 needs to be exposed except for two ends, the other parts are sleeved with the first insulating layer 11, and the other parts of the loop electrode tube 2 need to be exposed except for two ends, and the other parts are sleeved with the second insulating layer 21. In this embodiment, the emitter sub-needle 1 and the first wire 4 are fixedly connected together by welding, and the first connector 14 formed by the emitter sub-needle 1 and the first wire 4 is arranged in the storage box 6, so that the emitter sub-needle 1 and the first wire 4 can be prevented from being disconnected due to pulling or the like of external force. In other embodiments, the emitter sub-needle 1 and the first conductive wire 4 may be electrically connected together by other connection methods, which is not limited by the present application.
In some alternative embodiments, a first opening 611 is disposed on the first side 61 of the storage box 6, the first opening 611 penetrates through the first side 61, one end of the second wire 5 is connected to a conductive buckle 51, and the buckle 51 is clamped in the first opening 611 and contacts with the loop pole 2, so as to electrically connect the loop pole 2 with the second wire 5. Because the buckle 51 is directly connected to the second lead 5 and electrically connected to the second lead 5, when the handle 3 part of the ablation electrode assembly optimizing the internal structure of the handle is assembled, the loop electrode tube 2 can be contacted by directly clamping the buckle 51 into the first opening 611, and the electrical connection between the loop electrode tube 2 and the second lead 5 can be conveniently and rapidly realized.
In some alternative embodiments, the buckle 51 is an elastic metal buckle 51, a hook 511 is further disposed on the buckle 51, and a second opening 612 is further disposed on the first side 61 of the storage box 6, in this embodiment, the second opening 612 penetrates through the first side 61, and the hook 511 is snapped into the second opening 612 from the inner side of the first side 61, so that the buckle 51 is more firmly snapped into the first opening 611, and the buckle 51 is ensured to keep contact with the loop pole tube 2 all the time. The inner side surface is the surface close to the loop pole pipe 2. In other embodiments, the second opening 612 may not penetrate the first side 61, but a groove is formed in the inner side of the first side 61, and the groove does not penetrate the outer side of the first side 61, and the hook 511 is engaged into the groove from the inner side of the first side 61. The outer side surface is the surface far away from the loop pole pipe 2.
In this embodiment, the distal end of the loop pole tube 2 is used as the loop pole 23, and the first lead wire 4 and the second lead wire 5 are electrically connected to an ablation host (not shown in the figure), and the ablation host provides a loop signal for the loop pole 23 through the second lead wire 5 and the loop pole tube 2. In addition, an insulating base 9 is fixedly arranged at the end part of the loop pole 23, an emitter 12 is fixedly arranged on the insulating base 9, the emitter 12 is electrically connected with the distal end of the emitter sub-needle 1, and an ablation host supplies an ablation signal to the emitter 12 through the first lead 4 and the emitter sub-needle 1. In other embodiments, the emitter electrode 12 and the return electrode 23 may be configured in other forms, which are not particularly limited in the present application.
In some alternative embodiments, a hollow protrusion 31 extending along the length direction of the handle 3 is disposed on the inner side of the distal end of the handle 3, and a sleeve 22 is sleeved on the part of the loop pole tube 2, where the sleeve 22 is composed of a first part 221 and a second part 222 with different outer diameters, the outer diameter of the first part 221 is larger than that of the second part 222, and one end of the first part 221 is fixedly connected with the second end face 63 of the distal end of the receiving box 6. The second portion 222 is disposed in the hollow channel 311 of the protrusion 31 and abuts against the inner side surface of the distal end of the handle 3, and the abutting means that the second portion 222 may or may not be in contact with the inner side surface of the distal end of the handle 3. In addition, the outer diameter of the first portion 221 is larger than the diameter of the hollow passage 311, so that the first portion 221 abuts against the end face of the proximal end of the projection 31, so that the position of the loop pole tube 2 with respect to the handle 3 is fixed.
In some alternative embodiments, 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 are wrapped together with a sheath 45, one end of the sheath 45 is fixed in the housing box 6, and the rest of the sheath 45 protrudes from the first end surface 62 at the proximal end of the housing box 6.
In a possible implementation, as shown in fig. 3, the main difference between this embodiment and the ablation electrode assembly of the embodiment shown in fig. 1 is that a gasket 2221 is sleeved on the second portion 222, the outer diameter of the gasket 2221 is larger than the diameter of the hollow channel 311, and the gasket 2221 is pressed between the bump 31 and the first portion 221. The gasket 2221 is effective to prevent liquid from flowing into the handle 3 to cause short-circuit failure.
In one possible implementation, as shown in fig. 4 and 5, the main difference between the embodiment and the embodiment shown in fig. 1 and 2 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 through the curing glue 7, so that the connection between the emitter sub-needle 1 and the first lead 4 is firmer, and the emitter sub-needle 1 and the first lead 4 can be prevented from being disconnected due to pulling or the like caused by external force because the emitter sub-needle 1 is cured by the curing glue 7. The loop pole tube 2, the first insulating layer 11, the first lead 4, the second lead 5 and the sheath 45 which are positioned in the storage box 6 are also encapsulated and fixed in the storage box 6 by the curing adhesive 7, the components are more firmly fixed in the storage box 6, and the curing adhesive 7 can prevent liquid, impurities and the like from entering the storage box 6 to cause short circuit phenomenon. In addition, the second wire 5 extending from the clip 51 contacting the inner loop pole tube 2 of the storage box 6 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 adhesive 7 may be a UV adhesive, a sealant or other adhesive that is easy to cure, and some of the curing adhesives 7 are transparent or translucent, and in fig. 4 and 5, the curing adhesives 7 are drawn in a hatched form to more clearly show the content of the present invention, which is not intended to limit the present invention. In other embodiments, the cured adhesive 7 may be replaced by another insulating filler material, 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. When the ablation electrode assembly is assembled, the first connector 14, the proximal end of the loop electrode tube 2, part of the first insulating layer 11, the first lead 4, the second lead 5 and the sheath 45 are placed in the storage box 6 which is not filled with the curing adhesive 7, the curing adhesive 7 is poured into the storage box 6, the curing adhesive 7 covers the first connector 14, the proximal end of the loop electrode tube 2, part of the first insulating layer 11, the first lead 4, the second lead 5 and the sheath 45, and after the curing treatment of the curing adhesive 7, the first connector 14, the proximal end of the loop electrode tube 2, part of the first insulating layer 11, the first lead 4, the second lead 5 and the sheath 45 are sealed and fixed in the storage box 6.
In some alternative embodiments, only the first connector 14, the proximal end of the loop pole tube 2, a portion of the first insulating layer 11, a portion of the first wire 4 may be disposed within the housing box 6, and the second wire 5 and the sheath 45 may be disposed outside the housing box 6, which is not particularly limited by the present application.
In another possible implementation, as shown in fig. 6 and 7, the main difference between this embodiment and the ablation electrode assembly of the embodiment shown in fig. 1 and 2 is the structure of the receiving box 6 in the ablation electrode assembly.

The storage box 6 in this embodiment includes a first housing 64 and a second housing 65 that are snapped 51 together, and the first connector 14, the proximal end of the loop pole tube 2, and portions of the first insulating layer 11, the first wire 4, the second wire 5, and the sheath 45 are all disposed within the first housing 64, with the second housing 65 covering the first housing 64. In addition, the second wire 5 extending from the clip 51 contacting the inner loop pole tube 2 of the storage box 6 extends outside the storage box 6, then extends into the storage box 6 from an opening 651 on the second housing 65, and finally extends from the first end surface 62 at the proximal end of the storage box 6. A first through opening 611 is formed in the first side 61 of the first housing 64, a portion of the second wire 5 and the clip 51 pass through the opening 651 in the second housing 65, and the clip 51 is snapped into the first opening 611 at the junction with the loop pole tube 2. A second opening 612 is disposed on the first side 61 of the first housing 64, and the hook 511 is snapped into the second opening 612. In this embodiment, the first housing 64 and the second housing 65 are snapped together by the engagement of grooves and protrusions, and in other embodiments, they may be detachably engaged together in other manners.
The first connector 14, the proximal end of the loop pole tube 2, part of the first insulating layer 11, the first lead 4, the second lead 5 and the sheath 45 are arranged in the storage box 6 through the first shell 64 and the second shell 65 which are buckled together, so that the first connector 14 is better prevented from being broken due to pulling of external force.
In some alternative embodiments, only the first connector 14, the proximal end of the loop pole tube 2, a portion of the first insulating layer 11, a portion of the first wire 4 may be disposed within the housing box 6, and the second wire 5 and the sheath 45 may be disposed outside the housing box 6, which is not particularly limited by the present application.
In some alternative embodiments, with continued reference to fig. 6, 7 and 8 (fig. 8 is a schematic view of the structure of the first housing 64 of the receiving case 6 in fig. 7 disposed in the ablation electrode assembly optimizing the internal structure of the handle), a baffle 641 is disposed in the first housing 64, the baffle 641 being disposed on an upper side of a bottom surface of the first housing 64, the upper side facing the second housing 65, the baffle 641 separating the first housing 64 from a first recess 642 and a second recess 643, the first connector 14 being disposed in the first recess 642, the second recess 643 being for disposing a suction tube 8, the suction tube 8 being for sucking out saline. The first connector 14 may be disposed in the second groove 643, and the suction tube 8 may be disposed in the first groove 642. The first connector 14 and the suction tube 8 are isolated by the baffle 641, do not affect each other, and facilitate the operation when assembling the handle 3 of the ablation device. In addition, a third recess 644 is provided in the first housing 64, and the proximal end of the loop pole tube 2 extends from the second end 63 of the housing 6 opposite the first end 62 and is disposed in the third recess 644, thereby stabilizing the loop pole tube 2 in the first housing 64.
In other embodiments, the baffle 641 may not be disposed in the first housing 64. The present application is not particularly limited.
In another possible implementation manner, as shown in fig. 9, the main difference between the embodiment and the embodiment shown in fig. 6 and 8 is that the storage box 6 is filled with the insulating curing glue 7, and the first connector 14 is encapsulated and fixed in the storage box 6 through the curing glue 7, so that the connection between the emitter sub-needle 1 and the first wire 4 is firmer, because the emitter sub-needle 1 is cured by the curing glue 7, and the emitter sub-needle 1 and the first wire 4 can be better prevented from being disconnected due to pulling or the like of external force. The proximal end of the loop pole tube 2 in the storage box 6 and part of the first insulating layer 11, the first conducting wire 4, the second conducting wire 5, the sheath 45 and the suction tube 8 are also encapsulated and fixed in the storage box 6, the components are more firmly fixed in the storage box 6, and the solidified glue 7 can further prevent the short circuit phenomenon caused by the entry of liquid, impurities and the like into the first joint 14. It should be noted that the curing adhesive 7 may be a UV adhesive, a sealant or other adhesive that is easy to cure, and some of the curing adhesives 7 are transparent or translucent, and in fig. 9, the curing adhesive 7 is drawn in a hatched form to more clearly show the content of the present invention, which is not intended to limit the present invention. In other embodiments, the cured adhesive 7 may be replaced by another insulating filler material, 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. When the ablation electrode assembly is assembled, the first connector 14, the proximal end of the loop electrode tube 2 and part of the first insulating layer 11, the first lead 4, the second lead 5, the sheath 45 and the suction tube 8 are placed in the first housing 64 of the storage box 6 which is not filled with the curing adhesive 7, the first connector 14 is arranged in the first groove 642, the suction tube 8 is arranged in the second groove 643, the proximal end of the loop electrode tube 2 is arranged in the third groove 644, the second housing 65 is placed on the first housing 64, part of the second lead 5 and part of the clip 51 penetrate out of the first opening 651 on the second housing 65 and clip the clip 51 into the first opening 611 on the first housing 64, the second housing 65 is subsequently clipped on the first housing 64, finally the curing adhesive 7 is poured into the storage box 6 from the opening 651 on the second housing 65, the curing adhesive 7 covers the first connector 14, the proximal end of the loop electrode tube 2 and part of the first insulating layer 11, the second lead 4, the second lead 5, the second lead 45, the sheath 7 and part of the first lead 8 are sealed and the first insulating layer 4, the second lead 8 and the second lead 8 are packaged in the first housing 6.

In another possible implementation, as shown in fig. 10, the main difference between this embodiment and the embodiment shown in fig. 1 is that one end of the emitter sub-needle 1 and one end of the first wire 4 are fixedly connected together at the first joint 14 by a metal connecting sleeve 141. In order to achieve a better connection, the emitter sub-needle 1 at the first joint 14 is soldered to the first wire 4 in this embodiment.
