Embodiment 1

[0031] Embodiment one, by figure 1 Provided, the present invention includes a base 2, the upper end of the base 2 is provided with a head fixing mechanism 1, and the head fixing mechanism 1 is used to fix the patient's head, so as to avoid long-term treatment of the head from shifting and affecting the treatment effect. The lower end of the seat 2 is provided with a support frame 3, the support frame 3 is used to support the base 2 and the head fixing mechanism 1, the rear end of the support frame 3 is fixedly connected with a rotating shaft 4, and the rear end of the rotating shaft 4 is provided with an adjustment mechanism 5 , the adjusting mechanism 5 can drive the rotating shaft 4 to rotate around the axis of the rotating shaft 4, and the adjusting mechanism 5 can also drive the rotating shaft 4 to perform a circular swing. Angle adjustment.

Embodiment 2

[0032] Embodiment two, on the basis of embodiment one, by figure 1 , figure 2 , image 3 with Image 6 Given, in order to be able to fix the heads of different patients and open and close the head fixation mechanism 1, the head fixation mechanism 1 includes a first clamping mechanism 18 and a second clamping mechanism 19 that are symmetrical to each other. A clamping mechanism 18 comprises the first connecting rod 6, the second connecting rod 7, the third connecting rod 8, the fourth connecting rod 9, the fifth connecting rod 10 and an arc-shaped guide rod 42, the upper end of the guide rod 42 is connected to the first The ends of a connecting rod 6 and the second connecting rod 7 are hinged with a pin rod 33, and the lower end of the guide rod 42 is provided with an arc-shaped guide groove 11, and the guide groove 11 is provided with a pin rod 33 that can slide along the guide groove 11. Pin rod 33 is hinged with the middle part of the third connecting rod 8 and the fourt...

Embodiment 3

[0035] Embodiment three, on the basis of embodiment two, by Image 6 with Figure 7 Given, in order to realize the extruding and fixing of the extruding block 36 to the patient's head, the telescoping rod 34 includes a hollow tube 39, and the hollow tube 39 is provided with a sliding rod 38 that can slide up and down in the hollow tube 39, A spring 40 is fixedly connected between the sliding rod 38 and the bottom end of the cavity pipe 39, and the spherical joint 35 is rotatably embedded in the upper end of the sliding rod 38 to form a ball-hinged structure, because the telescopic rod 34 is provided with a spring 40, so When the extruding block 36 is extruded, a reaction force will be exerted on the patient's head, thereby realizing extruding and fixing the patient's head.

Abstract

The invention relates to a head fixing device for tumor radiotherapy. The problems are effectively solved that during common radiotherapy, the height and angle of the head fixing device cannot be adjusted according to the treatment demand of a patient, and the fixing device cannot be adjusted according to the shape and size of the head of the patient. The device comprises a base, a head fixing mechanism is arranged at the upper end of the base, and a supporting rack is arranged at the lower end of the base; a rotation shaft is fixedly connected to the rear end of the supporting rack, and an adjustment mechanism is arranged at the rear end of the rotation shaft, can drive the rotation shaft to rotate around the axis of the rotation shaft and can also drive the rotation shaft to conduct circumference swing. The head fixing device is novel in structure and ingenious in concept. By means of the head fixing device, the head of the patient is fixed at multiple angles and heights, and the device helps a medical worker to handle a more complex condition. The comfort of the patient and working efficiency of the medical worker are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a head fixation device for tumor radiotherapy. Background technique [0002] Tumor radiation therapy refers to the use of radioactive isotope rays to accelerate the production of high-energy X-rays to kill tumor cells and treat benign and malignant tumors. Most malignant tumors of the head and neck can be effectively treated with radiotherapy, but radiotherapy for the head and neck requires high positioning of the radiotherapy position, so the patient's head needs to be fixed during radiotherapy. [0003] The current radiotherapy head immobilization device on the market has a single function, and the fixed angle and height cannot be adjusted according to the physical conditions of different patients. The current head immobilization device cannot adjust the height and angle of the head immobilization position according to the treatment needs, and different patients have d...
