Description

Technical Field

[0001] The present application relates to the technical field of medical radio frequency treatment equipment, and in particular to a radio frequency temperature control treatment device. Background Art

[0002] Radiofrequency temperature control therapy generally refers to radiofrequency ablation therapy, which is a minimally invasive thermal ablation technology that has been widely, safely and effectively used in the treatment of neurosurgery and pain. As a commonly used special equipment for radiofrequency temperature control therapy, radiofrequency temperature control equipment uses one or several radiofrequency electrodes and a neutral electrode to connect to the patient. The radiofrequency electrode is inserted into the patient's lesion area under the auxiliary positioning of CT, and the neutral electrode is attached to the patient's skin surface. Before radiofrequency treatment, the lesion area where the radiofrequency electrode is inserted is first located by electrical impedance and electrical stimulation to ensure the accurate position of the lesion. When radiofrequency occurs, when the radiofrequency current flows through the radiofrequency electrode, the patient's tissue and the neutral electrode to form a loop, it will produce a thermal effect on the tissue around the radiofrequency electrode, causing the tissue at the lesion location to dehydrate and coagulate, thereby achieving a therapeutic effect.

[0003] There are many styles and models of radio frequency temperature control treatment equipment currently on the market, but they are basically large devices with large dimensions and weigh at least seven kilograms. They are not convenient for individuals to move at will. They are generally equipped with a trolley for moving the equipment, so that the entire combined equipment is larger and takes up more space, so it is only suitable for use in empty operating rooms. In radio frequency temperature control treatment, for some special lesion locations and the patient's own conditions, it is sometimes impossible to achieve a good treatment effect through one or short-term treatment. In this case, it is usually necessary to insert a soft electrode that can be placed for a long time at the lesion site, and multiple or long-term radio frequency treatments are required. However, the radio frequency temperature control treatment equipment currently available on the market is large in size and not convenient to move. It can generally only be operated and used in an operating room or treatment room. For multiple or long-term treatments, it is necessary to frequently go in and out of the operating room for professional treatment, which is complicated and costly.

[0004] In addition, this type of large-scale radiofrequency temperature control treatment equipment has rich functions and can generally only be operated by trained doctors or nurses, which greatly limits the convenience and wide range of its use. Utility Model Content

[0005] In order to improve the portability, convenience and wide application of radio frequency temperature control treatment equipment, the present application provides a radio frequency temperature control treatment equipment.

[0006] The radiofrequency temperature control treatment device provided in this application adopts the following technical solutions:

By adopting the above-mentioned technical scheme, independent selection can be made according to the actual usage scenario. Doctors or nurses can make specific settings for the treatment parameters of different patients in the medical interface, and the patient interface only has a switch function to start the treatment.

The box 10 is also provided with an alarm prompt module 90 electrically connected to the main control board 30; the alarm prompt module 90 includes an alarm light or an alarm speaker or a combination of the two. The alarm prompt is given for different situations by different flashing frequency and color of the alarm light and the volume and frequency of the sound broadcast by the alarm speaker; when an erroneous operation occurs during treatment or the treatment is ended, an alarm is issued in different ways to remind the user, thereby improving the safety and convenience of the use of the device.

[0045] Reference Figure 1 and Figure 2 As shown, in the present application, a Bluetooth module 80 electrically connected to the main control board 30 is also provided in the box 10; the Bluetooth module 80 is used for wireless communication, and medical staff can set the functional data on the device through the host computer. At the same time, the treatment data of the device can be wirelessly transmitted to the host computer for archiving and retention, thereby further improving the convenience, reliability and standardization of the radio frequency temperature control treatment equipment.

[0046] The implementation principle is as follows: the radio frequency temperature control treatment device in the present application can be used in conjunction with a soft electrode that can be embedded in the human body. The soft electrode is detachably connected to one end of the radio frequency electrode line, and the other end of the radio frequency electrode line is plugged into the radio frequency electrode jack 72, also forming a detachable connection. One end of the neutral electrode line is detachably attached to the patient's skin surface, and the other end of the neutral electrode line is plugged into the neutral electrode jack 71. When in use, radio frequency temperature control treatment can be started through a simple connection. The radio frequency temperature control treatment device in the present application is equipped with a power socket 60 and a rechargeable battery 20. It can be connected to an external power supply for use in a fixed position, or it can be powered by the rechargeable battery 20 and carried around for use; the input of the power socket 60 can be a DC power supply, and connecting the power socket 60 through a power adapter can greatly reduce the volume of the entire device.

[0047] The device in this application has two operating interfaces, medical and patient, which can be selected independently according to the actual usage scenario. Doctors or nurses can make specific settings for treatment parameters of different patients in the medical interface, and the patient interface only has a switch function to start treatment. When the patient uses it alone, it is usually pulsed radio frequency, and the treatment temperature does not exceed 45°C; if it exceeds 45°C, it needs to be implemented under the supervision of a doctor; this can effectively avoid misoperation, and its functions are simple and easy to operate. When using it, the patient only needs to be told by the nurse to complete the operation alone, which is more flexible and convenient to use, thereby increasing the wide use of the device.

[0048] Because the radio frequency electrode needs to be inserted into the patient's lesion area under the assistance of CT, MRI and other imaging positioning, the first radio frequency treatment operation is generally performed in the operating room. The doctor buries the soft electrode in the patient's lesion area and uses the radio frequency temperature control treatment equipment for related treatment. After the treatment, the soft electrode connector is unplugged from the radio frequency electrode line connected to the radio frequency temperature control treatment equipment and properly placed on the patient. When follow-up treatment is required, the medical staff will first set the parameters of the radio frequency temperature control treatment equipment in this application: including treatment mode, treatment time, etc., and then carry out treatment.

[0049] During use, first turn on the power switch 13 of the device, the touch LCD screen 50 lights up and enters the standby state, and the patient can start treatment by turning on the treatment function. The treatment can be stopped at any time during the treatment. The treatment process can be monitored in real time by the host computer through wireless Bluetooth. If necessary, the host computer can also perform remote control operations. If there is any objection to the lesion target position of the electrode needle, the medical care interface can also be entered, and the medical staff can reconfirm the target through impedance positioning.

[0050] Reference Figure 3 and Figure 4 As shown, the radio frequency temperature control treatment device in the present application can be used while lying down or can be carried around for use. Therefore, snap connectors 11 are provided at the front and rear ends of the box body 10, and a shoulder strap 12 is detachably connected between the two snap connectors 11. When the patient uses it by himself, the entire device can be hung on the body through the shoulder strap 12, which reduces restrictions on the patient's posture and range of motion during the treatment process, and further improves the convenience and comfort of radio frequency temperature control treatment.

[0051] The principle of impedance positioning by the impedance measurement module 32 of the radio frequency temperature control treatment device in the present application is: different parts or nuclei in the human body have different impedance values, such as bones, nerves, brain gray matter, etc., which is caused by inconsistent water content. Under normal circumstances, by comparing different impedance values, the approximate position of the needle tip can be distinguished, which can be used as a basis for identifying the lesion point clinically. This function is usually used in the process of inserting surgical electrodes. During surgery, the surgical electrode is slowly inserted along a certain path, and the tested impedance value is observed at the same time. By comparing the theoretical value, it can be known whether the insertion path of the electrode is correct and whether it has accurately reached the lesion point. It is also possible to insert the surgical electrode after the electrode sheath needle reaches the imaging position, and observe whether the displayed impedance value meets the requirements, so as to determine whether the target position needs to be fine-tuned.

[0052] The principle of radio frequency temperature control treatment by the radio frequency module 40 and the temperature measurement module 31 in the radio frequency temperature control treatment device of the present application is: when continuous radio frequency treatment is required, the radio frequency current controlled by the radio frequency module 40 is continuously output during the entire treatment time, and the instrument adjusts the output radio frequency current in real time according to the temperature of the target point, so that it is constant at a set value until the treatment time ends. It is generally believed that human tissue will produce irreversible permanent damage above 45°C; and damage at 40°C-45°C can temporarily form an edema area at the target position, causing it to temporarily lose some biological properties, and this edema area can disappear and return to its original state. Under normal circumstances, when the temperature of the tissue wrapping the exposed end of the electrode is 60°C or above, the water content of the cells in the nucleus is lost, and coagulation occurs, and the biological activity is lost, which is irreversible damage, referred to as "thermal coagulation". When pulsed radio frequency treatment is required, the radio frequency current controlled by the radio frequency module 40 is output intermittently during the entire treatment time. Similarly, the instrument adjusts the output RF current in real time according to the set parameters, so that the actual parameters meet the set parameters until the treatment time is over. Pulsed RF is a new method of RF treatment, usually used on nerves.

[0053] The radio frequency module 40 of the radio frequency temperature control treatment device in the present application has a relatively small power, not exceeding 30W, and supports pulsed radio frequency output, and also supports high voltage pulsed radio frequency, with an effective value of not less than 70V.

[0054] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
