Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ablation, and in particular to an ablation consumable and an ablation system. Background Art
[0002] Currently, various minimally invasive interventional ablation techniques have been widely and maturely used in the field of clinical soft tissue ablation treatment.
[0003] For example, in radiofrequency ablation therapy, an electrode needle is placed directly into the tumor tissue through percutaneous puncture under the guidance of imaging technology. Under the action of radiofrequency current, the polar molecules in the tumor tissue oscillate at high speed and rub against each other, producing a biothermal effect, which causes the temperature of the treatment area to reach 60-100°C, thereby causing coagulation and necrosis of tumor tissue cells, thereby achieving the purpose of completely killing the lesions.
[0004] Microwave ablation is a thermal ablation technology that can be applied to tumor treatment. Microwaves are used to quickly heat biological tissues, causing the tumor tissues to denature and necrotize due to heat, thereby achieving the purpose of treating tumors. The mechanism of microwave heating is mainly through the action of electromagnetic fields, which causes the friction of dipoles such as water molecules in the tissue to generate heat. It can quickly generate a large amount of heat energy in a short period of time, causing the tissue to reach a high temperature. Compared with other thermal ablation technologies such as radio frequency and laser ablation, microwave ablation has the characteristics of fast heating, strong blood vessel coagulation ability, little influence by blood flow factors, and a large and stable normal coagulation range. It is a technology with good application prospects in thermal ablation treatment technology.
[0005] Steep pulse therapy uses high-voltage pulses to cause irreversible electrical breakdown of the cell membrane. Under the action of a steep pulse with a certain electric field strength, a large number of micropores will form on the cell membrane. The number and pore size of micropores will increase sharply with the increase of the electric field strength, thereby causing membrane tissue rupture and leading to cell death.
[0006] Cryoablation is a method of freezing diseased tissues through cryogenic technology to achieve the purpose of inactivating solid tissues in situ. The principle of action is to use low temperature to quickly cool down the diseased tissues, thereby causing ice crystal damage, solute damage and microvascular embolism to the cells, causing cell necrosis or apoptosis, and achieving the purpose of treatment. Since cryoablation uses the physical method of energy exchange to achieve the purpose of treatment, its trauma and side effects to the human body are far lower than conventional radiotherapy and chemotherapy, so it is hailed as a "green therapy".
[0007] At present, various ablation treatment instruments, consumables and equipment need to have ablation energy signal transmission pathways, detection, control, and indication photoelectric signal pathways, and cooling medium transmission pathways. Each transmission pathway is relatively independent, and there are many connecting wires / pipes between the equipment and consumables, making the connection cumbersome for clinical use. Due to the space limitations of the operating room, the operator and the equipment need to be separated by a certain distance, the equipment needs to be controlled through the equipment end, and the indication of the equipment's working status is on the equipment end. Both operation and status indications are not conducive to direct control and observation by the operator. In addition, the specifications and models of the consumables and equipment parameters need to be manually identified and controlled. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0029] Embodiment 1
[0030] This embodiment provides an ablation consumable connected to an ablation device, such as Figure 1 As shown, the ablation consumable includes a needle rod 2, a needle head 1 connected to one end of the needle rod 2, and a handle 3 supporting the needle rod 2; the ablation consumable also includes:
[0031] An indication module 5, arranged on the handle 3, for indicating the parameters and / or status of the ablation consumables and / or the parameters and / or status of the ablation device;
[0032] At least one switch module 7, disposed on the handle 3, for controlling the ablation device to perform a preset action;
[0033] The connector 10 is disposed between the handle 3 and the ablation device, and is used to realize a bidirectional signal connection between the ablation consumable and the ablation device.
[0034] The needle 1 is used to puncture the target tissue (such as a tumor) and deliver ablative energy to the target tissue; in practical applications, according to the ablative energy signal transmitted, the material of the needle 1 can be a metal material such as medical stainless steel, or a non-metal material such as ceramic material, PTFE, PI, PEEK, etc., and the surface of the needle 1 has an anti-stick coating. The ablative energy can be an energy signal such as microwave, radio frequency, cryotherapy, high-voltage steep pulse, electrolysis, etc.
[0035] The needle rod 2 is used for transmitting ablation energy, and the ablation energy is transmitted on its internal structure and / or itself; the material of the needle rod 2 can be metal materials such as medical stainless steel, or non-metal materials such as ceramic materials, PTFE, PP, PEEK, etc., and the surface of the needle rod 2 is partially or completely covered with an isolation layer.
[0036] The handle 3 is used as a handheld device for the operator during ablation treatment, and is used to support components such as the needle rod 2, the indication module 5, and the switch module 7; the material of the handle 3 can be metal materials such as stainless steel and aluminum alloy, or non-metal materials such as ABS and PC.
[0037] The switch module 7 can be in the form of a membrane switch, a tactile switch, a touch switch or a coding switch, etc. The switch module 7 is composed of corresponding switch devices and matching circuits.
[0038] The connector 10 may be in the form of a multi-core quick-plug connector or an aviation connector.
[0039] The preset actions may include, but are not limited to, starting, resetting, and stopping the ablation device. The switch module 7 may be one or more. In the case where there is one switch module 7, different preset actions can be controlled by different operations on the switch module 7, for example, the ablation device is started when the switch module 7 is clicked, the ablation device is reset when the switch module 7 is long pressed, and the ablation device is stopped when the switch module 7 is double-clicked. In the case where there are multiple switch modules 7, different switch modules 7 can be used to control the ablation device to perform different preset actions.
[0040] In this embodiment, the ablation consumable can realize the indication of parameters and / or status and the switch control of preset actions. When the signal of the ablation consumable and the ablation device is bidirectionally connected, the ablation device can be directly controlled to perform the preset action through the switch module at the consumable end, and the parameters and / or status of the current ablation device / ablation consumable can be indicated through the indication module 5. It is not limited to the environmental space limitations of the ablation operation, has a simple structure, and is easy to operate.
[0041] In some implementations, the indication module 5 includes at least one lamp including a single-color or multi-color LED, at least one lamp array including a single-color or multi-color LED, an LCD display module, an LED dot matrix display module, an OLED dot matrix display module, or any combination thereof, and may specifically be composed of corresponding modules and supporting circuits. Wherein, in the case where the indication module 5 includes at least one lamp array including a single-color or multi-color LED, the lamp array including a single-color or multi-color LED is disposed around the switch module 7.
[0042] In some implementations, the ablation consumable further includes a transmission module 9 , which is connected between the connector 10 and the handle 3 and is used to implement signal cross-connection of the indication module 5 and / or the switch module 7 .
[0043] In some implementations, the ablation consumable also includes a cooling chamber 4, which is disposed inside the handle 3 and is used to carry and distribute the cooling medium under the thermal ablation method; accordingly, the transmission module 9 is also used to transmit the ablation medium under the cryoablation method.
[0044] In this embodiment, the cooling chamber 4 provides a cooling medium (such as a cooling liquid) for carrying and distributing the cooling medium for the thermal ablation method that requires the use of the cooling medium. The structure of the cooling chamber 4 can be a single-chamber structure or a multi-chamber structure. The material of the cooling chamber 4 can be a metal material such as stainless steel, aluminum alloy, or a non-metal material such as ABS, PC, etc.
[0045] In this embodiment, the transmission module 9 can be used as a signal transmission line and a transmission pipeline for energy such as cooling medium. As an example, the transmission module 9 can adopt the ablation composite transmission line provided by the utility model patent with publication number CN218792466U, which not only reduces the number of ablation consumables and ablation equipment signal connection lines, but also makes clinical operation more convenient; it also reduces the number of transmission lines / pipelines, improves the integrity and aesthetics of ablation consumables, and avoids the problem of each transmission line / pipeline crossing each other; and the cooling medium and energy signal are parallel or wrapped around the energy transmission signal line, which can also provide a cooling function for the energy signal cable.
[0046] In some implementations, the ablation consumable also includes a modulation module 8, which is connected between the connector 10 and the indication module 5 and / or the switch module 7, and is used to modulate the signal of the indication module 5 and / or the switch module 7 into a signal of a set form and transmit it to the ablation device via the connector 10.
[0047] In some implementations, the ablation consumable also includes an identification module 6, located on the handle 3 or the connector 10, or connected to any position between the handle 3 and the connector 10, for storing parameters of the ablation consumable for identification by the ablation device; the transmission module 9 is also used to implement signal cross-connection of the identification module 6.
[0048] like Figure 2 As shown, the identification module 6 is located on the connector 10 and is directly welded to the core pin of the connector 10. When the connector 10 is connected to the ablation device, the identification module 6 can directly exchange information with the ablation device, which can reduce the number of signal transmission cables in the transmission module 9 and reduce the outer diameter of the composite cable. The switch module 7 adopts a touch switch and is placed at the center of the rear end of the handle 3, which can facilitate the actual clinical switch operation. The indication module 5 adopts a light array composed of multiple single-color or multi-color LED modules arranged around the switch module 7 to indicate different working states of ablation consumables or ablation devices. The indication module 5 and the switch module 7 are both placed at the rear end of the handle 3, so that they can be directly located within the operator's handle grip and the best visual range during clinical use, thereby improving the simplicity of operation and the intuitiveness of the indication. Furthermore, the modulation module 8, the indication module 5, and the switch module 7 can also be integrated on a printed circuit board PCBA (Printed Circuit Board Assembly), effectively reducing the overall volume of each module.
[0049] In this embodiment, the modulation module 8 can modulate one or more signals in the indication module 5 and / or the identification module and / or the switch module 7 into a specific digital level signal or communication signal, or connect the signal of the indication module 5 and / or the identification module and / or the switch module 7 to the transmission module 9, and then transmit it to the connector 10 by the transmission module 9. In some cases, the modulation module 8 can also modulate the signal of the indication module 5 and / or the identification module and / or the switch module 7 into a wireless signal, and transmit it to the ablation device in a wireless manner.
[0050] In this embodiment, the identification module 6 includes any one of a resistor-capacitor component, a storage chip, a QR code, and an RFID tag, and can be composed of corresponding devices and supporting circuits. The parameters of the ablation consumables stored in the identification module 6, such as specifications and models, service life, maximum working time, maximum energy, etc., can be indicated by the indication module 5. In addition, the indication module 5 can also indicate the state and / or parameters of the ablation device. The state of the ablation device is, for example, the ablation range corresponding to the ablation time, and the parameters of the ablation device are, for example, microwave ablation energy parameters. The subsequent ablation device can also provide treatment parameters or treatment suggestions based on parameters such as specifications and models of the ablation consumables.
[0051] When the identification module 6 is a resistor-capacitor type element, the information of the resistor-capacitor type element is identified by the ablation device to obtain the parameters of the ablation consumable. When the identification module 6 is a two-dimensional code, it can be a graphic two-dimensional code. When the identification module 6 is a storage chip or an RFID tag, the parameters of the ablation consumable can be stored in the storage chip or the RFID tag in advance.
