Problems solved by technology

[0004] However, there are still some deficiencies in the radio frequency therapeutic apparatus, such as overheating pain caused by difficulty in cooling, it is still difficult to achieve the killing effect of tumor tissue during the treatment process, and the treatment effect needs to be improved
Moreover, due to the fixed working mode of the electrodes of the hyperthermia device, the use of large-area "wave field" irradiation including tumor tissue will cause damage to normal tissue, and because the energy is not focused, the treatment efficiency will be low, and it is difficult to completely destroy the tumor in the body Nutritious blood bed, completely kill tumor tissue, its curative effect is still difficult to meet the requirements of the current medical field of tumor

[0021] refer to figure 1 , the multi-electrode dual-spectrum radio frequency tumor hyperthermia instrument capable of focusing electromagnetic fields of the present invention comprises radio frequency electrodes, dual radio frequency sources, a power amplifier, a control cabinet, a power supply, a computer and a treatment bed, and the radio frequency electrodes are respectively connected to two power amplifiers through a switch , the two power amplifiers are respectively connected to the 100KHz low RF source and the 13.5MHz high RF source through two matching devices, the 100KHz low RF source and the 13.56MHz high RF source are respectively connected to the control cabinet, and the control cabinet is connected to the power supply, computer and treatment bed respectively , the computer is also connected to the power supply, the two power amplifiers are respectively connected to two data processors, and the two data processors are respectively connected to two controllers. The ra...

Embodiment 2

[0024] refer to image 3 , different from Embodiment 1, this embodiment takes the radio frequency electrode circumferential array as an example, and the number of electrodes is 15 as an example, assuming that the tumor is located at a point in the first quadrant of the transverse section of the human body lying flat, image 3 1 selected in 1 -1 8 ;1 2 -1 9 ;1 3 -1 10 ;1 4 -1 12 ;1 5 -1 13 ;1 6 -1 14 ;1 7 -1 15 A total of 7 sets of electrode pairs, from image 3 It can be seen from the figure that the number of electrodes is an odd number, and the appropriate electrode pair is selected according to the position of the tumor in the coordinate system. The cylinder area formed by each selected electrode pair is an eccentric area, which can cover the first The location of the tumor within the quadrant facilitates focused treatment of non-central tumors. When working, the 7 sets of electrode pairs can work in sequence, or multiple sets of electrode pairs can work in c...

Embodiment 3

[0027] refer to Figure 4 , Figure 5 and Figure 6 , different from Embodiment 1, this embodiment takes the radio frequency electrode circumferential array as two circles of electrodes, and the number of electrodes on each circle is 17 as an example. When working, the tumor is in the first circle of electrodes 1 and the second circle. Between the circle electrodes 2, according to the position of the tumor in the coordinate system, the electrodes on the first circle electrode 1 and the second circle electrode 2 are selected to form an electrode pair, assuming that the tumor position is at a point in the first quadrant of the human body’s horizontal cross-section , Figure 5 and Figure 6 1 selected in 1 -2 9 ;1 2 -2 10 ;1 3 -2 10 ;1 4 -2 11 ;1 5 -2 12 ;1 6 -2 13 ;1 7 -2 14 ;1 8 -2 16 ;2 1 -1 9 ;2 2 -1 10 ;2 3 -1 10 ;2 4 -1 11 ;2 5 -1 12 ;2 6 -1 13 ;2 7 -1 14 ;2 8 -1 16 There are 16 sets of electrode pairs in total. The selected electrode pair...

Abstract

The invention discloses a multi-electrode bispectrum radio frequency tumor thermotherapy instrument capable of focusing an electromagnetic field, and belongs to medical apparatuses and instruments for tumor therapy. The multi-electrode bispectrum radio frequency tumor thermotherapy instrument comprises a radio frequency electrode, a dual-radio-frequency source, two power amplifiers, a control cabinet, a power source, a computer and a therapy bed. The radio frequency electrode is respectively connected with the power amplifiers through a diverter switch. The power amplifiers are respectively connected with the dual-radio-frequency source through two matchers. The dual-radio-frequency source is connected with the control cabinet. The control cabinet is respectively connected with the power source, the computer and the therapy bed. The multi-electrode bispectrum radio frequency tumor thermotherapy instrument is characterized in that the number of electrode bodies of a radio frequency electrode circumferential array is an odd number from 5 to 37, noncentral tumor focusing therapy is facilitated due to the design, tumor target tissue can be selectively and rapidly heated by means of the action of the electromagnetic field applied to the radio frequency electrode array, the tumor heating efficiency is improved, a tumor nutrition blood bed inside the body of a patient can be effectively damaged, and the problem that normal tissue is damaged by large-area wave field irradiation inside the tumor tissue can be avoided.

Description

Technical field: [0001] The invention belongs to tumor medical equipment, in particular to a multi-electrode dual-spectrum radio frequency tumor thermotherapy instrument capable of focusing electromagnetic fields. Background technique: [0002] Surgical treatment of tumors is recognized as one of the best treatment methods, followed by treatment equipment used to inhibit and directly kill tumor cells include x-ray radiotherapy machine, γ-ray knife, laser knife and so on. However, for some patients with advanced stage and poor physical conditions who are not suitable for surgical treatment, other treatment methods must be adopted, such as radiotherapy, chemotherapy, hyperthermia, freezing, alcohol embolism and other methods, wherein hyperthermia is another treatment after radiotherapy and chemotherapy. It is an important tumor treatment method, and it is a green treatment method without any damage to the human body. According to the mechanism of tumor formation and the chara...
