Description

Technical Field

[0001] The present invention belongs to the technical field of tumor treatment auxiliary equipment in the field of medical equipment, and specifically relates to a thermal therapy auxiliary device for tumor internal medicine. Background Art

[0002] The hyperthermia assist device in oncology is a device that uses thermal effects to assist in the treatment of tumors; the side effects are relatively small: compared with chemotherapy and radiotherapy, the side effects of hyperthermia are relatively mild, and generally do not cause serious bone marrow suppression, gastrointestinal reactions or radiation damage. Common side effects include local skin burns, pain, fever, etc., which can be relieved after proper treatment in most cases. Wide range of applications: Hyperthermia can be used to treat a variety of tumors, including lung cancer, breast cancer, liver cancer, gastric cancer, colorectal cancer, cervical cancer, prostate cancer, etc., especially for those patients who cannot be surgically removed and are resistant to chemotherapy or radiotherapy, hyperthermia provides a new treatment option. Can be combined with a variety of treatment methods: Hyperthermia can be combined with chemotherapy, radiotherapy, immunotherapy, targeted therapy and other tumor treatment methods to exert a synergistic effect and improve the treatment effect.

[0003] Currently, common external hyperthermia devices include radiofrequency (RF) hyperthermia devices, microwave (MW) hyperthermia devices, and focused ultrasound (UUS) hyperthermia devices. RF hyperthermia devices generate heat through radiofrequency current and can target deep-seated tumors. Microwave hyperthermia devices use microwave radiation to warm tumor tissue and are suitable for superficial tumors or those within body cavities. Focused ultrasound (UUS) devices focus low-energy ultrasound waves from outside the body on the tumor site, generating high temperatures that kill tumor cells. They offer advantages such as accurate targeting and minimal damage to surrounding tissues.

[0004] During actual use of the above-mentioned equipment, the radio frequency generator, microwave generator, microwave radiator, and ultrasonic transducer located on the equipment are responsible for providing the energy required for heat therapy. The energy required for heat therapy is always located on a certain part of the human body for heat therapy. The part located on the relatively back of a certain part of the human body lacks the energy required for heat therapy, resulting in poor heat therapy effect; in addition, high temperature control requirements are required during the heat process, usually controlled between 40-43°C. The efficacy of heat therapy is closely related to temperature. Too high a temperature may cause damage to normal tissues, and too low a temperature will not achieve the therapeutic effect. Among them, 40-43°C also includes 41-42°C, that is, the existing technology maintains it between 40-43°C, and it is impossible to reasonably use 41-42°C according to the physique of different people, or use any temperature between 40-43°C according to actual conditions.

The present invention may also be implemented or applied through specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] Hyperthermia-assisted oncology devices belong to the tumor treatment assistive device sub-segment within the medical device field. From a disciplinary perspective, they are primarily used in the field of oncology, particularly in oncology, to assist in the hyperthermia treatment of tumors. Hyperthermia therapy involves raising the temperature to supraphysiological levels, causing biological changes in tumor tissue or cells, thereby killing tumor cells. This device is designed to achieve optimal hyperthermia effectiveness, while also improving treatment safety and comfort.

[0025] The thermotherapy device body 1 in this embodiment is an N-9000 microwave tumor thermotherapy device; the N-9000 microwave tumor thermotherapy device is a multifunctional thermotherapy system, which was developed and produced by Xuzhou Novan Medical Equipment Co., Ltd. and introduced US military wave control technology. It solves the technical problems of previous microwave products that cannot effectively heat deep tissues and accurately measure and control temperature during the heating process. Through a large number of animal experiments and years of clinical trials, it has been proved that the N-90000 thermotherapy device can effectively heat the deep tissues and the whole body of the human body. It has a complete structure, easy operation, stable performance, safety and reliability. It is a new generation of large-scale medical equipment for treating tumors with internationally advanced and domestically leading levels.

[0026] like Figure 1 、 Figure 2 As shown, in order to improve the hyperthermia effect of the N-9000 microwave tumor hyperthermia device, the present invention provides a hyperthermia auxiliary device for oncology, which includes a hyperthermia device body 1, which includes a bed frame 2 and a hyperthermia energy conversion mechanism arranged on the bed frame 2, and the bed frame 2 moves back and forth under the hyperthermia energy conversion mechanism; and further includes: a hyperthermia auxiliary mechanism 4, which is arranged on the bed frame 2, wherein the bed frame 2 is a three-section structure, that is, the bed frame 2 includes a front section, a middle section, and a rear section, the hyperthermia auxiliary mechanism 4 is arranged at the middle section of the bed frame 2, the patient's hyperthermia site is located above the hyperthermia auxiliary mechanism 4, and the hyperthermia auxiliary mechanism 4 and the hyperthermia energy conversion mechanism simultaneously release thermal energy for hyperthermia.

[0027] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 14As shown, a protective assembly 3 is symmetrically arranged at the middle position of the bed frame 2 to prevent the patient from falling off the bed frame; the protective assembly 3 includes: a first protective member 3-4, a second protective member 3-3, a telescopic member 3-2, and a switch 3-1. The first protective member 3-4 is a rectangular plate, and the second protective member 3-3 is a rectangular plate, wherein the second protective member 3-3 is provided with a slide groove, the telescopic member 3-2 is an electric telescopic rod, and the switch 3-1 starts the switch. The lower end of the first protective member 3-4 is mechanically connected to the middle section of the bed frame 2, the telescopic member 3-2 is arranged in the slide groove, and the fixed end is connected to the inside of the slide groove. The second protective member 3-3 is also arranged in the slide groove, and one end of the second protective member 3-3 is fixedly connected to the telescopic end of the telescopic member 3-2. The switch 3-1 is installed on the first protective member 3-4 and is electrically connected to the telescopic member 3-2. When the switch 3-1 is activated, the telescopic end of the telescopic member 3-2 drives the second protective member 3-3 to extend out of the slide slot and extend to the front section of the bed frame 2; again, when the switch 3-1 is activated, the telescopic end of the telescopic member 3-2 drives the second protective member 3-3 to retract into the slide slot.

[0028] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 As shown, the rear section of the bed frame 2 is fixedly connected to the middle section, and the front section and the middle section are rotatably connected by a hinge. A mounting frame is provided below the bed frame 2, and the mounting frame is slidably connected to the base of the therapeutic instrument body 1, so that the mounting frame of the bed frame 2 slides on the base of the therapeutic instrument body 1, and the frame is below the middle section of the bed frame 2; a lifting mechanism 4-10 is provided below the middle section of the bed frame 2, and the lifting mechanism 4-10 is located in the mounting frame. The lifting mechanism 4-10 is a ball screw, which includes a driving member, a third transmission member, a sliding member, and a connecting member 202. The driving member is a driving motor, and the third transmission member is a sliding member. The three transmission components are a lead screw and a slider. The connecting member 202 consists of two sections, with a 35-degree angle between them. The lead screw is rotatably connected to the drive motor through a mounting bracket, and the slider is slidably connected to the lead screw. The drive motor is fixed at the bottom of the mounting frame. One end of the connecting member 202 is connected to the slider shaft, and the other end is connected to the shaft at the lower end of the front end of the bed frame 2. When the drive motor is turned on, it drives the lead screw to rotate, which in turn drives the slider on the lead screw to move up and down. The slider's up and down movement drives the connecting member 202 up and down, and then rotates around the middle section of the bed frame 2 at the front section. The patient lies on the bed frame 2 with his head and chest positioned on the front section. When the front section and the middle section are at a certain angle, the patient can be assisted in getting up.

[0029] like Figure 7-13As shown, a mounting hole is provided at the center of the middle section of the bed frame 2, and three equidistant annular grooves are provided on the lower end surface of the middle section of the bed frame 2; the heat therapy auxiliary mechanism 4 includes: a bearing 4-8, a heating component, an elastic component, a sliding rheostat 4-7, a support 4-6, and an electrical connector 4-4. The bearing 4-8 is a bearing plate, the heating component is a heating wire 4-3, the elastic component is an annular spring, the sliding rheostat 7-7 is a thermal resistance temperature transmitter, the support 4-6 is two insulating support rods, and the electrical connector 4-4 is two rectangular conductors. The bearing 4-8 is provided in the mounting hole, and the outer contour of the bearing 4-8 matches the contour of the mounting hole. The bearing 4-8 moves up and down in the mounting hole, and the sliding rheostat 4 -7 is vertically mounted at the top of the lead screw. The sliding rheostat 4-7 is mechanically connected to the lead screw via a connector. The lower end of the elastic component is mechanically connected to the top of the sliding rheostat 4-7, which is fixedly connected to the lower end surface of the support member 4-8. After installation, the support member 4-8 is 1 cm above the middle surface of the bed frame 2. The support member 4-6 is obliquely mounted below the support member 4-8. One end of the support member 4-6 is mechanically connected to the lower end surface of the support member 4-8, and the other end is connected to the sliding component on the sliding rheostat 4-7. The heating wire 4-3 is arranged in an annular groove. The two ends of the heating wire 4-3 are connected in series via rectangular conductors. The two rectangular conductors are electrically connected to the output terminals on the sliding rheostat 4-7. In this way, the downward movement of the support member 4-8 drives the sliding component on the sliding rheostat 4-7 downward, reducing the output voltage of the sliding rheostat while maintaining the same current. The heating component heats at high power, while heating at low power.

[0030] The operating principle of rheostats 4-7 is to change the resistance of a resistor wire by varying the length of the wire connected to the circuit, thereby varying the current and voltage in the circuit. Specifically, a rheostat generally consists of a resistor wire, a slider, a terminal, and an insulating tube. The resistor wire is wound around the insulating tube, and the material typically has a high resistivity. As the slider slides across the resistor wire, the length of the wire connected to the circuit changes. According to the resistance law R=ρSL (where R represents resistance, ρ represents resistivity, L represents conductor length, and S represents conductor cross-sectional area), for constant resistivity ρ and cross-sectional area S, resistance R is proportional to length L. Therefore, changing the length of the resistor wire connected to the circuit changes its resistance. For example, in a series circuit, when the slider of a rheostat moves in the direction that increases the length of the resistor wire connected to the circuit, its resistance increases. According to Ohm's law I=RU, for a constant supply voltage U, the current I in the circuit decreases; conversely, the current increases. At the same time, since the resistance divider in the series circuit is proportional to the size of the resistance, the voltage across the sliding rheostat will also change with the change of resistance.

[0031] Sliding rheostat 4-7 is electrically connected to heating wire 4-3. As the sliding element of sliding rheostat 4-7 moves, its resistance increases or decreases, correspondingly increasing or decreasing the resistance of heating wire 4-3. When the resistance increases, the voltage decreases, while the current remains constant, resulting in high-power heating of heating wire 4-3. When the resistance decreases, the voltage increases, while the current remains constant, resulting in normal-power heating of heating wire 4-3. The principle of voltage division in a series circuit: In a series circuit, the total voltage equals the sum of the voltages of each component of the circuit, and the voltage distribution is proportional to the resistance. According to Ohm's law, U=IR, when current I remains constant (current is constant everywhere in a series circuit), an increase in resistance R increases the voltage U across that resistor. However, when the power supply voltage remains constant, the voltages across the other resistors decrease accordingly. For example, in a series circuit consisting of two resistors R1 and R2, the power supply voltage is ΔV. According to the series circuit voltage division formula, ΔV = ΔV, when R1 increases, the voltage U across R1 increases, while the voltage U across R2 decreases. The impact of actual power supply internal resistance: Actual power supplies all have internal resistance. When the external circuit resistance increases, the total current decreases, the power supply internal resistance voltage (I is the current, r is the power supply internal resistance) decreases, and the external circuit voltage (terminal voltage) (E is the power supply electromotive force) increases. If we consider a resistor in the external circuit as the research object, when its resistance increases, its proportion of the voltage division in the entire external circuit will increase, while the voltage division of other resistors will decrease.

[0032] like Figure 15As shown, the performance of the heating wire 4-3 will decline after long-term use. In order to facilitate the subsequent replacement of the heating wire 4-3, the thermal therapy auxiliary mechanism 4 also includes a transmission component 4-9, a wire take-up component 4-1, a roller 4-2, and an annular electrical connector 4-5. The annular electrical connector 4-5 is a coil spring, the wire take-up component 4-1 is a wire take-up wheel, and the material is a conductive material. The transmission component 4-9 is an electric material. The transmission component 4-9 includes a first transmission component and a second transmission component. The second transmission component is a hollow shaft, and the first transmission component is The shaft is provided with a fixed ring at the end of the shaft, the insulating fixed ring is sleeved on the top of the lead screw and fixedly connected, the fixed ring is located below the sliding rheostat 4-7 to prevent the sliding rheostat 4-7 from affecting the fixed ring and the rotation of the shaft, the annular electrical connector 4-5 is sleeved on the sliding rheostat 4-7, and a gap is left between them, one end of the annular electrical connector 4-5 is electrically connected to the transmission component 4-9, and the other end is electrically connected to the sliding component on the sliding rheostat 4-7, the heating wire 4-3 is electrically connected to the take-up component 4-1, and the heating wire 4-3 is electrically connected to the take-up component 4-1. The other end of the wire 4-3 is fixed to the middle section of the bed frame 2 through a rectangular conductor, so that the electric energy of the sliding rheostat 4-7 is transmitted to the heating wire 4-3 through the annular electrical connector 4-5, the first transmission component, the second transmission component, and the wire take-up component 4-1; the second transmission component is sleeved on the first transmission component, and the second transmission component is rotatably connected to the first transmission component, and the wire take-up component 4-1 is sleeved on the second transmission component and fixedly connected, so that the lead screw drives the first transmission component to rotate, and then the second transmission component and the wire take-up component 4-1 rotate in opposite directions, and the heating wire 4-3 is wound around the wire take-up component 4-1 during the reverse rotation, that is, after the first transmission component completes one circle of rotation, the heating wire 4-3 is wound around the wire take-up component 4-1; conversely, the lead screw drives the first transmission component to rotate, and then the second transmission component and the wire take-up component 4-1 rotate in opposite directions, and the heating wire 4-3 is arranged on the wire take-up component 4-1 during the reverse rotation, that is, after the first transmission component completes one circle of rotation, the heating wire 4-3 is wrapped around the wire take-up component 4-1.

[0033] Tumor cells are more sensitive to temperature than normal cells. When the local temperature rises to a certain level (generally 40-43°C), tumor cell metabolism is inhibited, DNA, RNA, and protein synthesis is blocked, and cell membrane permeability increases, leading to tumor cell apoptosis or necrosis. Hyperthermia therapy can also enhance the body's immune function, promoting immune cell recognition and killing of tumor cells. Hyperthermia can increase tumor cell membrane permeability, facilitating the entry of chemotherapy drugs into tumor cells, increasing intracellular concentrations of chemotherapy drugs, and thus enhancing the efficacy of chemotherapy. Hyperthermia therapy can also inhibit tumor cell resistance to chemotherapy drugs, resensitizing previously resistant tumor cells.

[0034] Hyperthermia can dilate blood vessels within tumor tissue, increasing blood flow and improving oxygen supply to the tumor. Hypoxia is a key factor in tumor cell resistance to radiotherapy. Therefore, hyperthermia can increase the sensitivity of tumor cells to radiotherapy and enhance the local control rate of radiotherapy. For some patients with advanced cancer, pain can result from tumor invasion of peripheral nerves or tissue ischemia and hypoxia. Hyperthermia can alleviate pain symptoms and improve patients' quality of life by improving local blood circulation, reducing tissue edema, and inhibiting the excitability of nerve endings.

[0035] Working principle: Figure 2 This is the initial state of the thermotherapy device body 1 in this embodiment; after the patient lies on the bed frame 2, the patient's body is pressed on the bearing member 4-8. During the descent of the bearing member 4-8, the supporting member 4-6 is driven to descend, thereby driving the sliding member on the sliding rheostat 4-7 to descend, and the heating wire 4-3 is heated at high power; 1) the driving motor is started, and the driving motor drives the lead screw to rotate, and the slider on the lead screw descends, thereby driving the connecting member 202 to descend. After the connecting member 202 descends, it pulls the front section of the bed frame 2 down and is parallel to the middle section of the bed frame 2; at the same time, the lead screw drives the first transmission component to rotate, thereby the second transmission component The moving parts and the wire-taking part 4-1 rotate in opposite directions, wherein the first transmission part rotates, the second transmission part rotates, and the wire-taking part 4-1 only needs to complete one circle of movement. During the reverse rotation of the second transmission part and the wire-taking part 4-1, the heating wire 4-3 is arranged in the groove on the middle section of the bed frame 2, that is, after the first transmission part completes one circle of rotation, the wire-taking part 4-1 rotates multiple circles and the heating wire 4-3 is arranged in the receiving groove; 2) Start the switch 3-1, the telescopic part 3-2 pushes the second protective part 3-3 out of the slide groove on the first protective part 3-4, and extends to the reference section of the front section of the bed frame 2 Figure 1 As shown; 3) the bed frame 2 moves to the heat therapy energy conversion mechanism on the heat therapy device body 1, and the heat therapy energy conversion mechanism generates heat energy and the heating wire 4-3 generates heat energy at the same time to perform heat therapy on the patient.

[0036] 4) After the heat therapy is completed, the bed frame 2 moves away from the heat therapy energy conversion mechanism on the heat therapy device body 1; the drive motor is started, and the drive motor drives the lead screw to rotate in the opposite direction, and the slider on the lead screw rises, thereby driving the connecting member 202 to rise. After the connecting member 202 rises, it pushes the front section of the bed frame 2 to rise, and forms a 30-degree angle with the middle section support of the bed frame 2; at the same time, the lead screw drives the first transmission component to rotate in the opposite direction, and then the second transmission component and the take-up component 4-1 rotate forward, among which the first transmission component and the second transmission component only need to complete one circle of movement, and the take-up component 4-1 completes multiple circles of movement. The second transmission component and the take-up component 4-1 rotate forward during the process The heating wire 4-3 is wound around the take-up member 4-1, that is, after the first transmission member completes one circle of rotation, the take-up member 4-1 completes multiple circles of movement and the heating wire 4-3 is wound around the take-up member 4-1; 5) the switch 3-1 is started, and the telescopic member 3-2 drives the second protective member 3-3 to retract into the sliding groove on the first protective member 3-4; 6) the patient holds the protective component with his hand and stands up. After standing up, the patient's body is away from the supporting member 4-8, and the supporting member 4-8 rises under the elastic force of the spring. During the rising process, it drives the supporting member 4-6 to rise, and then drives the sliding member on the sliding rheostat 4-7 to rise, and the heating wire 4-3 is heated at a low power.
