In some embodiments, referring to fig. 3, the first runner 0231 is "T" shaped. The number of the first chutes 0231 is equal to the number of the electrode assemblies 024. Here, the specific number of the first chutes 0231 or the electrode assemblies 024 is not limited, and different numbers of the electrode assemblies 024 or the first chutes 0231 may be set based on the actual application scene of the ablation device, except that the number of the electrode assemblies 024 is equal to the number of the first chutes 0231. In some embodiments, referring to fig. 5 (a) and 5 (b), if the knob assembly 021 is rotated clockwise, the gear assembly 022 connected to the knob assembly 021 is rotated, so as to drive the electrode assembly 024 to slide outwards along the first chute 0231, such that the electrode assembly expands outwards (e.g., the electrode assembly is changed from the configuration of fig. 5 (a) to the configuration of fig. 5 (b)), and the ablation range of the ablation device is enlarged. Accordingly, when the knob assembly 21 is rotated counterclockwise, the gear assembly 022 connected to the knob assembly 021 is rotated, so as to drive the electrode assembly 024 to slide inward along the first chute 0231, such that the electrode assembly 024 is contracted inward (e.g., changed from the configuration of fig. 5 (b) to the configuration of fig. 5 (a)), and the ablation range of the ablation device is reduced. Here, the clockwise rotation of the knob assembly causes the electrode assembly to expand outward and the counterclockwise rotation causes the electrode assembly to contract inward, which is only an example, and it may also be configured that the counterclockwise rotation of the knob assembly causes the electrode assembly to expand outward and the clockwise rotation causes the electrode assembly to contract inward, which is not limited in this application.

Referring to fig. 6, in some embodiments, the electrode assembly 024 includes a sliding arm 0242 and an electrode 0241, the sliding arm 0242 is fixedly connected with the electrode 0241, and the sliding arm 0242 is disposed in the first chute 0231. In some embodiments, the electrode 0241 has a circular arc plate shape. The sliding support arm 0242 is fixedly connected with one end of an inner arc surface of the electrode 0241. The width of the sliding support arm 0242 is slightly smaller than the width of the first sliding groove so as to slide smoothly in the first sliding groove.

Referring to fig. 2, 4 and 6, in some embodiments, the gear assembly 022 includes a first gear assembly 0221 and a second gear assembly 0222, the first gear assembly 0221 is fixedly connected to the knob assembly 021, the first gear assembly 0221 is engaged with the second gear assembly 0222, and the second gear assembly 0222 is provided with a plurality of second chutes 022211; the electrode assembly further includes a sliding post 0243, the sliding post 0243 being disposed on the sliding arm 0242, the sliding post 0243 passing through the second chute 022211; when the knob component 021 is acted on, the first gear component 0221 is driven to rotate, so that the second gear component 0222 is driven to rotate, and the sliding column 0243 is acted on to drive the sliding support arm 0242 to move along the first sliding groove 0231. In some embodiments, the first gear assembly 0221 has a diameter that is less than the second gear assembly 0222. The number of the second chutes 022211 is the same as that of the first chutes 0231. In some embodiments, the sliding legs 0242 of the electrode assembly 024 are disposed in the first sliding groove 0231, and the sliding posts 0243 of the sliding legs 0242 also penetrate the second sliding groove 022211 of the second gear assembly 0222 disposed on the fixed disk 023. Thus, when the knob assembly 021 is rotated, the first gear assembly 0221 is driven to rotate, and since the first gear assembly 0221 is engaged with the second gear assembly 0222, the second gear assembly 0222 is also driven to rotate. When the second gear assembly 0222 rotates, the second sliding groove 022211 in the second gear assembly 0222 applies a force to the sliding column 0243 passing through the second sliding groove 022211 due to the rotation, so that the sliding column 0243 is forced to move the sliding arm 0242 along the first sliding groove 0231.

Referring to fig. 3 and 4, in some embodiments, the first gear assembly 0221 includes a first gear 02211 and a first gear shaft 02212, the first gear shaft 02212 is disposed on the fixed wheel 023, and the first gear shaft 02212 is fixedly connected to the knob assembly 021. In some embodiments, the first gear 02211 and the first gear shaft 02212 may be integrally formed or may be separately formed. The first gear shaft 02212 penetrates the center of the first gear 02211. The first gear shaft 02212 is coaxially connected with the knob assembly 021. The knob assembly 021 is activated to rotate the first gear shaft 02212, and the first gear shaft 02212 rotates the first gear 02211.

Referring to fig. 2, in some embodiments, the knob assembly 021 includes an adjusting knob 0211 and an adjusting knob stem 0212, one end of the adjusting knob stem 0212 is fixedly connected to the first gear shaft 02212, and the other end of the adjusting knob stem 0212 is detachably connected to the adjusting knob 0211. In some embodiments, the adjusting knob 0211, the adjusting knob stem 0212 and the first gear shaft 02212 are all coaxially disposed. When the adjusting knob 0211 is rotated, the adjusting knob stem 0212 is driven to rotate, and the first gear shaft 02212 is driven to rotate. One end of the adjusting knob rod 0212 detachably connected with the adjusting knob 0211 penetrates through the closed end of the ablation barrel 01, so that the adjusting knob 0211 is exposed out of the ablation barrel 01, and the adjustment of a medical operator is facilitated.

In some embodiments, the knob assembly 021 further includes a ball plunger 0213, and the adjustment knob stem 0212 is provided with a groove into which a ball end of the ball plunger 0213 is pressed. In some embodiments, the portion of the adjusting knob stem 0212 exposed out of the closed end of the ablation barrel 01 is provided with a groove. The grooves are uniformly distributed along the circumferential direction of the adjusting knob rod 0212. The ball end of the ball plunger 0213 is pressed into the groove, and the knob assembly 021 plays a role in fixing when not acted. Moreover, due to the matching of the ball end of the ball plunger 0213 and the groove, when the knob component 021 is rotated by a medical operator, the medical operator can feel the change of the rotation resistance, and the rotation section feeling is realized.

Referring to fig. 2 to 4, in some embodiments, the second gear assembly 0222 includes a second gear 02221 and a second gear shaft 02222, and the second gear 02221 is provided with a plurality of second chutes 022211. In some embodiments, second gear shaft 02222 can be integrally formed with fixed disk 023. In some embodiments, the second gear shaft 02222 can also be integrally formed with the second gear 02221, and the fixed disk 023 has an axial hole for the second gear shaft 02222 to pass through, so that the second gear 02221 can rotate around the second gear shaft 02222, and the second gear 02221 is fixed in the axial direction.

Taking the example that the knob assembly 021 is rotated clockwise such that the electrode assembly 024 expands outward, and rotated counterclockwise such that the electrode assembly 024 contracts inward, if the adjustment knob 0211 is rotated clockwise, since the adjustment knob 0211, the adjustment knob stem 0212 and the first gear shaft 02212 are coaxially disposed, the adjustment knob 0211 will drive the adjustment knob stem 0212 and the first gear shaft 02212 to rotate clockwise, and the first gear shaft 02212 will drive the first gear 02211 to rotate clockwise. Since the first gear 02211 is engaged with the second gear 02221, when the first gear 02211 rotates clockwise, the second gear 02221 is driven to rotate counterclockwise. The counterclockwise rotation of the second gear 02221 applies an outward pushing force to the sliding cylinder 0243 passing through the second sliding groove 022211, so that the sliding cylinder 0243 is forced to move the sliding arm 0242 along the first sliding groove 0231, the electrode 0241 is expanded outward, for example, the electrode assembly 024 is changed from fig. 5 (a) to the configuration of fig. 5 (b), and the distance between the electrode assemblies 024 is increased, so that the ablation range of the ablation device is increased. On the contrary, if the adjusting knob 0211 is rotated counterclockwise, referring to the adjusting process, the adjusting knob 0211 will drive the adjusting knob rod 0212 and the first gear shaft 02212 to rotate counterclockwise, and the first gear shaft 02212 will drive the first gear 02211 to rotate counterclockwise, and then the second gear 02221 to rotate clockwise. The clockwise rotation of the second gear 02221 applies an inward pushing force to the sliding column 0243 penetrating through the second sliding groove 022211, so that the sliding column 0243 is forced to move the sliding arm 0242 inwards along the first sliding groove 0231, and the electrode 0241 contracts inwards. For reference, the electrode assemblies 024 can be transformed from the configuration of fig. 5 (b) to the configuration of fig. 5 (a), and the distance between the electrode assemblies 024 becomes smaller, so that the ablation range of the ablation device becomes smaller. Here, the clockwise rotation of the knob assembly causes the electrode assembly to expand outward and the counterclockwise rotation causes the electrode assembly to contract inward, which is only an example, and it may also be configured that the counterclockwise rotation of the knob assembly causes the electrode assembly to expand outward and the clockwise rotation causes the electrode assembly to contract inward, which is not limited in this application.

In some embodiments, the ablation device further comprises an electrode needle assembly 03, the second gear shaft 02222 penetrates the fixed wheel 023, and the second gear shaft 02222 is provided with a first electrode needle hole through which the electrode needle assembly 03 passes. In some embodiments, the electrode needle assembly 03 includes an electrode needle and a third wire, one end of the third wire is connected to the electrode needle, and the other end of the third wire is connected to a pulse output device. The electrode needle penetrates through the closed end of the ablation barrel to be inserted into the ablation barrel 01 and penetrates through the first electrode needle hole in the ablation barrel 01, so that the electrode needle can penetrate through the ablation barrel 01 to be inserted into the skin of a patient. Referring to fig. 1, in some embodiments, a sealing ring 04 is disposed on a closed end of the ablation barrel 01, and the sealing ring 04 is provided with a second electrode needle hole for the electrode needle assembly 03 to pass through. An electrode needle in the electrode needle assembly 03 penetrates through the closed end of the ablation barrel 01 through a second electrode needle hole in the sealing ring 04. After the electrode needle is inserted into the second electrode needle hole, the sealing ring 04 can ensure that the inside and the outside of the ablation barrel 01 are sealed. In some embodiments, the electrode needle assembly 03 can be configured as one pole (e.g., positive pole) and the electrode assembly 024 can be configured as the other pole (e.g., negative pole) to apply a pulsed voltage such that an electric field is formed between the electrode needle in the electrode needle assembly 03 and the electrode assembly 024 for ablation.

Referring to fig. 3 and 4, in some embodiments, the ablation device further includes a first lead 05, the first lead 05 being in series with at least 2 of the plurality of electrode assemblies 024. For example, if there are 4 electrode assemblies a, B, C, D, the first lead 05 may connect all of the electrode assemblies a, B, C, D in series according to the application requirement, or connect 2 or 3 electrode assemblies in series to form a group. The ablation may be performed by applying a pulse voltage to one electrode (e.g., positive electrode) of the electrode needle assembly 03 and the other electrode (e.g., negative electrode) of the plurality of electrode assemblies connected in series. For another example, the first lead 05 may connect the electrode assemblies a and B in series as one set, and connect the electrode assemblies C and D in series as one set; alternatively, the electrode assemblies A, B and C are connected in series to form a group, and the electrode assembly D is used as a group.

In some embodiments, the electrode assembly 024 to which the second lead 06 is connected is determined according to the series condition of a plurality of electrode assemblies 024 and the polarity arrangement condition of the plurality of electrode assemblies 024. For example, if a plurality of electrode assemblies 024 are connected in series into one group, and the electrode assembly needs to be set to a certain pole in the current ablation, the second lead wire 06 may be connected to any one of the electrode assemblies 024 in the group. For another example, if there are multiple sets of serially connected electrode assemblies 024, and the serially connected electrode assemblies all need to be set in polarity during the ablation, multiple second leads 06 are needed, and each second lead 06 needs to be connected to any one of the electrode assemblies 024 in one of the sets.
