Description

Technical Field

[0002] The pulse ablation device uses the principle of pulse ablation electric field, mainly applying a short and high pulse voltage between two electrodes made of special materials, so that the original membrane potential of the cell changes, and irreversible nano-scale holes are generated in the lipid bilayer of the membrane, which destroys the homeostasis of the cell and causes cell death. Moreover, this ablation method only causes cell death in a specific area, while preserving the integrity of the cell's tissue scaffold, fiber structure, etc., while the tissues adjacent to the ablation area (such as blood vessels or surrounding normal tissues) are not damaged, avoiding the "heat sink effect" of the ablation area, which is conducive to the repair of the body.

DETAILED DESCRIPTION

[0064] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0065] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0066] See attached Figure 1-12 The present embodiment provides a pulse ablation device, comprising: an electrode assembly, comprising a first electrode 11 and a second electrode 12; an electrode ablation device 1, comprising a accommodating shell 13 and a support assembly partially disposed inside the accommodating shell 13; the first electrode 11 and the second electrode 12 are spaced apart on the accommodating shell 13, the connecting end of the first electrode 11 and the connecting end of the second electrode 12 both extend into the accommodating shell 13, and are clamped and fixed with the first end of the support assembly; a handle device 2 capable of providing current to the electrode assembly, the second end of the support assembly is connected to the handle device 2, and a pulse is formed between the first electrode 11 and the second electrode 12 when powered on.

[0067] It should be noted that: after the electrode ablation device 1 in the present embodiment is connected to the handle device 2, the handle device 2 provides current to the electrode assembly so that a pulse is formed between the first electrode 11 and the second electrode 12 that are spaced apart, so as to perform pulse ablation on the oral diseased tissue; the connecting end of the first electrode 11 and the connecting end of the second electrode 12 in the present application are both extended into the accommodating shell 12, and are clamped and fixed with the first end of the support assembly, thereby optimizing the structure of the electrode assembly and simplifying the installation structure of the electrode assembly, so that the connecting end of the electrode assembly is clamped and matched with the support assembly, thereby fixing the electrode assembly, thereby reducing the preparation cost and installation difficulty.

[0068] In this embodiment, the pulse ablation device is mainly used for oral lesion tissue. The electrode ablation device 1 in the pulse ablation device is extended into the oral cavity. The first electrode 11 and the second electrode 12 arranged on the surface of the accommodating shell 13 are attached to the oral lesion tissue to realize the pulse formed between the first electrode 11 and the second electrode 12 to ablate the oral lesion tissue.

[0069] Specifically, the pulse formed between the first electrode 11 and the second electrode 12 can emit a pulse with a width of microsecond level to the oral lesion tissue, so as to damage the stability of the cell membrane surface of the oral lesion tissue, and cause multiple hydrophilic micropores to appear on the surface of the oral lesion tissue cells, so as to destroy the homeostasis of the oral lesion tissue cells and cause the oral lesion tissue cells to die, thereby achieving the therapeutic effect of pulse ablation of the oral lesion tissue.

[0070] It is understandable that different oral tissue cells have different destruction thresholds. By controlling the magnitude of the pulse energy emitted by the first electrode 11 and the second electrode 12, the pulses emitted by the first electrode 11 and the second electrode 12 can be accurately directed to the lesion location, and the pulse ablation treatment has tissue cell selectivity; by controlling the magnitude of the pulse energy emitted by the first electrode 11 and the second electrode 12 corresponding to the oral lesion tissue cells, the pulse only performs pulse ablation treatment on the oral lesion tissue cells without destroying other tissue cells.

[0071] In this embodiment, the shapes of the first electrode 11 and the second electrode 12 are set according to actual conditions, and the first electrode 11 and the second electrode 12 can be of any shape.

[0072] Preferably, the first electrode 11 is a circular structure, the second electrode 12 is an annular structure, and the second electrode 12 is arranged on the outer peripheral side of the first electrode 11. By arranging the second electrode 12 on the outer peripheral side of the first electrode 11, it is possible to ensure that pulses are generated between the first electrode 11 and the second electrode 12 at any position, thereby increasing the area that can be ablated by the pulse ablation device, thereby improving the efficiency of the ablation treatment of the pulse ablation device.

[0073] In this embodiment, the electrode ablation device 1 is an elbow structure with an angle, and the angle range is 0-180°.

[0074] Preferably, the angle formed by the electrode ablation device 1 is 45°.

[0075] In some possible embodiments, one of the connection end of the electrode assembly or the first end of the support assembly is provided with a connection position, and the other is provided with a snap-fit ​​structure matching the connection position. Such a setting can further simplify the connection structure between the electrode assembly and the support assembly and reduce the difficulty of installing the electrode assembly.

[0076] In this embodiment, the connection position may be a region having at least one connection hole, a region having at least one connection groove, or a region having a connection structure.

[0077] In this embodiment, the specific structure of the support assembly is not limited, as long as the support assembly has a connection position or a clamping structure that matches the connection end of the motor assembly.

[0078] In some possible embodiments, a connecting position is provided at the first end of the support assembly, and a clamping structure cooperating therewith is provided at the connecting end of the electrode assembly.

[0079] In some other possible embodiments, the connection end of the electrode assembly is provided with a connection position, and the first end of the support assembly is provided with a clamping structure that cooperates therewith.

[0080] In some possible embodiments, the support assembly includes a first circuit board 15; the connection position is arranged on the first circuit board 15. By setting the connection position on the first circuit board 15, it can be ensured that the connection end of the electrode assembly is snap-fitted with the first circuit board 15, thereby achieving fixation of the electrode assembly. When replacing different first electrodes 11 or second electrodes 12 according to different scenarios, it is only necessary to adaptively replace them with the first circuit board 15 with corresponding connection positions. This enables the pulse ablation device in this embodiment to adapt to first electrodes 11 and second electrodes 12 of different sizes and shapes, thereby further improving the adaptability of the pulse ablation device.

[0081] In this embodiment, the specific structure of the first circuit board 15 is not limited, as long as the first circuit board 15 has connection positions.

[0082] In some possible embodiments, the first end of the support component is provided with multiple connection positions, and the multiple connection positions include a first connection position 151 and a second connection position 152 that are arranged at intervals; a snap-on structure is provided on the first electrode 11 and the second electrode 12; the first connection position 151 cooperates with the snap-on structure of the first electrode 11, and the second connection position 152 cooperates with the snap-on structure of the second electrode 12. By arranging the first connection position 151 and the second connection position 152 that are arranged at intervals, it can be ensured that after the first electrode 11 and the second electrode 12 are snap-fitted and fixed, the two will not interfere with each other, thereby ensuring the stability of the connection structure and thereby improving the safety of use of the pulse ablation device.

[0083] In this embodiment, the first connection position 151 is an area consisting of multiple connection holes, and the number of connection holes corresponds to the number and position of the first pins 111 of the first electrode 11. The second connection position 152 is an area consisting of multiple connection holes, and the number of connection holes corresponds to the number and position of the second pins 121 of the second electrode 11.

[0084] In this embodiment, the shape of the connection hole on the first connection position 151 is any shape, and the shape of the connection hole on the second connection position 152 is any shape, which is not limited here.

[0085] Preferably, the connection holes on the first connection position 151 and the connection holes on the second connection position 152 are both long holes. Such a configuration can facilitate the processing of the connection holes, and can also facilitate the processing of the first pin 111 and the second pin 121 that match them.

[0086] In this embodiment, the shape of the first connection position 151 area is the same as the shape of the area formed by the first pin assembly, and the shape of the second connection position 152 area is the same as the shape of the area formed by the second pin assembly.

[0087] When the first electrode 11 is a circular structure and the second electrode 12 is an annular structure, a group of first pin assemblies arranged on the first electrode 11 are arranged along the circumference of the first electrode 11, that is, the first pin assemblies form an annular structure; a group of second pin assemblies arranged on the second electrode 12 are arranged along the circumference of the second electrode 12, that is, the second pin assemblies form an annular structure; that is, the first connection position 151 and the second connection position 152 are both annular areas.

[0088] In some other possible embodiments, when the first electrode 11 and the second electrode 12 are both rectangular structures, a group of first pin assemblies arranged on the first electrode 11 are arranged along the axis of the first electrode 11, that is, the first pin assemblies form a hollow rectangular area, and a group of second pin assemblies arranged on the second electrode 12 are arranged along the circumference of the second electrode 12, that is, the second pin assemblies form a hollow rectangular area.

[0089] In some possible embodiments, the pulse ablation device satisfies at least one of the following features: the snap-on structure of the first electrode 11 includes at least one group of first pin assemblies spaced apart on the first electrode 11, the first pin assembly includes at least two first pins 111, and at least two first pins 111 are arranged along the circumference of the first electrode 11; the snap-on structure of the second electrode 12 includes at least one group of second pin assemblies spaced apart on the second electrode 12, the second pin assembly includes at least two second pins 121, and at least two second pins 121 are arranged along the circumference of the second electrode 12. Such an arrangement can ensure that the first electrode 11 can be firmly connected to the support assembly, and can ensure that the second electrode 12 can be firmly connected to the support assembly, thereby improving the safety of use of the pulse ablation device.

[0090] In some other possible embodiments, when at least two groups of first pin components are spaced apart on the first electrode 11, a number of first connection positions 151 corresponding to the number of first pin components need to be set; specifically, the multiple connection positions include at least two first connection positions 151 spaced apart, that is, each group of first pin components corresponds to one first connection position 151.

[0091] In this embodiment, each group of second pin components on the second electrode 12 corresponds to a second connecting position 152 .

[0092] In this embodiment, the first electrode 11 is a circular structure, the second electrode 12 is an annular structure, the first electrode 11 includes two groups of first pin components, and the second electrode 12 includes one group of second pin components.

[0093] In some possible embodiments, the first pin 111 includes an abutment portion 1111 and a connecting portion 1112 that are connected to each other; the connecting portion 1112 is snap-fitted to the first connecting position 151, and the abutment portion 1111 is electrically connected to the first circuit board 15. By setting the stepped abutment portion 1111 and the connecting portion 1112, a limiting effect on the first electrode 11 can be achieved, and it is ensured that the first electrode 11 is relatively parallel to the end face of the first circuit board 15 when the first electrode 11 is assembled.

[0094] In this embodiment, the structure of the second pin 121 is the same as that of the first pin 111, that is, the second pin is also a stepped structure. The second pin 121 can also realize the limiting effect on the second electrode 12, and can also ensure that the second electrode 12 is relatively parallel to the end face of the first circuit board 15 when the second electrode 12 is assembled.

[0095] In this embodiment, the length of the connection hole on the first connection position 151 is smaller than the width of the abutting portion 1111 and larger than the width of the connection portion 1112 .

[0096] In this embodiment, an abutment portion 1111 and a connecting portion 1112 are sequentially arranged along the length direction of the first pin 11, and the length direction of the first pin 11 is defined as the length direction of the abutment portion 1111 and the length direction of the connecting portion 1112. The width of the abutment portion 1111 is smaller than the width of the connecting portion 1112, so that the abutment portion 1111 can abut against the connecting hole on the first connecting position 151.

[0097] In some possible embodiments, the first pin 111 and the second pin 121 are both welded and fixed to the first circuit board 15; through holes are provided on the connecting portion 1112 of the first pin 111 and the connecting portion of the second pin 121. By providing the through holes, it is possible to ensure that when the pins are welded to the first circuit board 15, the solder flows through the through holes to form a lateral shear force, thereby further ensuring the gripping force and connection reliability during welding.

[0098] In this embodiment, after the pins of the first electrode 11 and the second electrode 12 are plugged into the first circuit board 15 , the pins are welded and fixed on the first circuit board 15 to fix the first electrode 11 and the second electrode 12 .

[0099] In some other possible embodiments, the first electrode 11 and the second electrode 12 are fixed to the first circuit board 15 by clamping or by gluing.

[0100] In some possible embodiments, the pulse ablation device satisfies at least one of the following characteristics: the first electrode 11 includes a first electrode arc surface 112 and a first bend portion 113, the first bend portion 113 is arranged along the edge of the first electrode arc surface 112, the first bend portion 113 is bent toward one side of the accommodating shell 13, and partially extends into the accommodating shell 13; the second electrode 12 includes a second electrode arc surface 122 and a second bend portion 123, the second bend portion 123 is arranged along the edge of the second electrode arc surface 122, the second bend portion 123 is bent toward one side of the accommodating shell 13, and partially extends into the accommodating shell 13. In this embodiment, the first bend portion 113 and the second bend portion 123 are electrode edges. By partially extending the first bend portion 113 and the second bend portion 123 into the accommodating shell 13, it is possible to avoid sparking or breakdown when the electrode edge contacts with a medium with different resistance values ​​in the air during use due to the tip discharge characteristics. Extending into the inside of the accommodating shell 13 effectively avoids the occurrence of tip discharge.

[0101] In this embodiment, the effective use area of ​​the first electrode 11 is the first electrode arc surface 112 , and the effective use area of ​​the second electrode 12 is the second electrode arc surface 112 .

[0102] In this embodiment, the connection between the first electrode arc surface 112 and the first bending portion 113 is a rounded structure, and the connection between the second electrode arc surface 122 and the second bending portion 123 is also a rounded structure. Under the same working conditions, the rounded structure is less likely to cause tip discharge, further avoiding the occurrence of tip discharge.

[0103] Specifically, the diameter of the rounded structure is 0.15-0.25 mm.

[0104] Preferably, the diameter of the rounded structure is 0.2 mm.

[0105] In this embodiment, the first electrode 11 and the second electrode 12 are both made of stainless steel.

[0106] In some possible embodiments, the pulse ablation device satisfies at least one of the following characteristics: the arc surface diameter of the first electrode arc surface 112 is 3.3-3.5 mm; the diameter of the second electrode arc surface 122 is 96.8-97 mm. Setting the above range can ensure the efficiency of the ablation treatment of the first electrode 11 and the second electrode 12, and ensure the maximum efficiency of the ablation treatment.

[0107] In this embodiment, the arc surface diameter of the first electrode arc surface 112 is 3.3-3.5 mm, 3.3-3.4 mm, 3.3-3.5 mm or 3.4-3.5 mm.

[0108] In this embodiment, the diameter of the second electrode arc surface 122 is 96.8-97 mm, 96.8-96.9 mm, 96.8-97 mm or 96.9-97 mm.

[0109] Preferably, the diameter of the first electrode arc surface 112 is 3.33 mm, and the diameter of the second electrode arc surface 122 is 96.8 mm.

[0110] In some possible embodiments, the pulse ablation device satisfies at least one of the following characteristics: the thickness of the first electrode 11 is 0.05-0.1mm; the thickness of the second electrode 12 is 0.05-0.1mm. By setting the above range, the thickness of the electrode assembly is very thin, and the curved surface of the electrode assembly is easily deformed by force. Therefore, when in use, if there is a tiny hard object on the contact surface, it will cause the curved surface of the electrode assembly to be squeezed and deformed, and will not greatly affect the poor fitting of the fitting surface. Compared with the overall hard plane without deformation, the ablation effect is better.

[0111] In this embodiment, the thickness of the first electrode 11 is 0.05-0.1 mm, 0.05-0.07 mm, 0.05-0.08 mm, 0.05-0.1 mm, 0.06-0.1 mm or 0.08-0.1 mm, etc.; the thickness of the second electrode 12 is 0.05-0.1 mm, 0.05-0.07 mm, 0.05-0.08 mm, 0.05-0.1 mm, 0.06-0.1 mm or 0.08-0.1 mm, etc.

[0112] In some possible embodiments, the ratio of the area of ​​the first electrode 11 to the area of ​​the second electrode 12 is 0.5-1.5. Setting the above range can maximize the pulse intensity formed between the first electrode 11 and the second electrode 12 on the basis of ensuring the formation of a pulse between the first electrode 11 and the second electrode 12, thereby improving the efficiency of the ablation treatment.
