Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a tumor radiotherapy treatment head. Background Art

[0002] Tumor radiation therapy (radiotherapy) is a treatment method that uses high-energy radiation (such as X-rays, gamma rays, etc.) to kill cancer cells or inhibit their growth. It is commonly used to treat many types of tumors, especially when the tumor cannot be removed by surgery or the patient is not a good candidate for surgery. Radiation therapy can be used in combination with surgery, chemotherapy or immunotherapy to help improve the effectiveness of treatment.

[0003] The radiotherapy treatment head usually refers to the treatment head part of the radiotherapy equipment. Specifically, it is a device on the radiotherapy machine (such as a linear accelerator, CT simulator, etc.) that is used to emit radiation to treat cancer or other diseases in patients. It is a key component in the radiotherapy process, responsible for accurately projecting high-energy radiation to the patient's target area to kill tumor cells while minimizing damage to surrounding healthy tissues.

[0004] CyberKnife is an advanced radiotherapy device, mainly used for precise treatment of tumors and other lesions. After use, the surface temperature of the CyberKnife treatment head (i.e. the transmitter of the CyberKnife) is too high, which may cause burns to medical staff if not touched, so it is urgent to solve the problem.

[0027] After the radiotherapy is completed, the shield 4 is threadedly installed on the surface of the ring 3. By setting a shield 4 on the outside of the emission source body 2, the shield 4 protects the emission source body 2 to prevent medical staff from touching the high-temperature emission source body 2, and an opening 401 is set on the circumferential surface of the shield 4 to facilitate heat dissipation; and a fan 10 that can perform circular motion is set on the outer circumferential surface of the shield 4, and the fan 10 is set to dissipate heat from the emission source body 2, thereby further improving the heat dissipation effect.

[0028] The outer circumferential side wall of the shield 4 is fixedly connected with a cooling box 13, and the top of the cooling box 13 is connected with a U-shaped tube 12, and both ends of the U-shaped tube 12 are respectively provided with a one-way valve 14 and a one-way valve 2 15.

[0029] A side branch pipe 18 is connected to the U-shaped tube 12, and an insertion rod 16 is movably inserted inside the side branch pipe 18. A spring 17 is fixedly connected between the insertion rod 16 and the side branch pipe 18. A magnet 2 19 is fixedly connected to the end of the insertion rod 16.

[0030] The cooling box 13 and the U-shaped tube 12 are provided to absorb the heat at the emission source body 2, and the fan 10 can make a circular motion. When the magnet 11 on the surface of the fan 10 corresponds to the position of the magnet 2 19 on the U-shaped tube 12, a repulsive force is generated. At this time, when the insertion rod 16 moves toward the U-shaped tube 12, the coolant is pushed into the cooling box 13 through the one-way valve 2 15; as the fan 10 continues to make a circular motion, when the magnet 11 on the surface of the fan 10 does not correspond to the position of the magnet 2 19 on the U-shaped tube 12, the spring 17 releases its elastic force, pushing the insertion rod 16 away from the U-shaped tube 12, and sucking the coolant into the U-shaped tube 12 through the one-way valve 14, thereby realizing the replacement of the coolant inside the U-shaped tube 12. The U-shaped tube 12 is provided at the opening 401 to facilitate heat absorption.

[0031] When the insertion rod 16 moves toward the U-shaped tube 12, the coolant is pushed into the cooling box 13 through the one-way valve 15; when the insertion rod 16 moves away from the U-shaped tube 12, the coolant is sucked into the U-shaped tube 12 through the one-way valve 14.

[0032] A motor 8 is fixedly mounted at the bottom of the shield 4 , a gear 7 is fixedly connected to the output end of the motor 8 , and the gear 7 is in meshing contact with the inner gear ring 6 .

[0033] The motor 8 is started to drive the gear 7 to rotate, the gear 7 drives the inner gear ring 6 to rotate, the inner gear ring 6 drives the fan 10 to rotate through the connecting rod 9, and the fan 10 blows air to the emission source body 2 to dissipate heat.
