Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly to a head fixation device for radiotherapy nursing. Background Art

[0002] As one of the core means of tumor treatment, the curative effect of radiotherapy highly depends on the precise positioning of the lesion area during the treatment process. Especially in the treatment of head tumors (such as glioblastoma, nasopharyngeal carcinoma) and stereotactic radiosurgery (SRS), millimeter-level displacement deviation may lead to insufficient target area dose or radioactive damage to surrounding sensitive tissues (such as the brainstem, optic nerve). Therefore, the rigid fixation and position repeatability of the patient's head are the key links to ensure the accuracy of radiotherapy.

[0003] Among them, the "chain conveyor device for conveying hot melt adhesive film" disclosed in the patent application number "CN210064159U" is also an increasingly mature technology, which "comprises a fixing frame, a guardrail, a chain conveyor belt and at least two transmission mechanisms; the fixing frame is arranged directly below the glue fishing chain, two said guardrails are relatively fixed to the front side and the rear side of the fixing frame, the transmission mechanism is fixed to the fixing frame, the chain conveyor belt is sleeved on the transmission mechanism, and the transmission mechanism drives the chain conveyor belt to rotate. The utility model changes the original belt conveyor to a chain conveyor belt and installs steel bars on the conveyor belt to ensure that the water on the surface of the product can fall by the gravity of the product itself, removing a part of the moisture, and the chain conveyor belt has good wear resistance, is not easy to generate dust particles, and will not affect the yield of the product.

[0004] Currently, the commonly used head fixation techniques in clinics mainly include thermoplastic film forming systems, vacuum negative pressure pads, and mechanical headrest-head frame combination devices. Although the thermoplastic film material has good plasticity, it has significant defects in practical applications: the airtight head fixation structure causes a strong sense of facial compression in patients during nursing, and has poor air permeability, which is easy to induce anxiety and involuntary micro-movement. Although the traditional head fixation device provides multi-point locking and cannot be adjusted, during head fixation, the rigid contact points are likely to cause local pressure sores of different sizes on the head, especially challenging the skin tolerance of elderly patients or long-term radiotherapy patients.

[0005] Therefore, it is necessary to provide a head fixation device for radiotherapy nursing to solve the above problems. Summary of the Invention

Two ends of the adjustment frame 306 are fixedly connected with first driving motors 307. The driving end of each first driving motor 307 is fixedly connected with a first lead screw 308. The outer side of the first lead screw 308 is threadedly connected with a moving seat 309, and one side of the moving seat 309 is slidably connected with the side of the adjustment frame 306;

[0037] During specific use, when fixing the head of a radiotherapy patient, in order to facilitate the pressing and fixing mechanism 4 to fit the patient's head for nursing and fixing the head of the radiotherapy patient, the telescopic movement of the third electric telescopic rod 305 is used to drive the connecting frame 303 for adjustment.

The bottom end of the rubber pressing head 404 is movably connected to one side of the end of the telescopic column 408.

[0040] During specific use, when fixing the head of a radiotherapy patient, in order to press and fix the head, the rotation of the second driving motor 402 is used to drive the second lead screw 403 to rotate. When the second lead screw 403 rotates, it is convenient to drive the small sliding seat 405 to slide, facilitating the adjustment of the telescopic column 408 to move closer to or away from each other, and adjusting according to the size of the radiotherapy head of the patient. The telescopic movement of the electric hydraulic cylinder 407 is used to push the telescopic column 408 for adjustment. During the adjustment of the telescopic column 408, it is convenient to push a number of rubber pressing heads 404 closer to the patient's head. The telescopic adjustment of a number of small hydraulic telescopic rods 409 drives the rubber pressing heads 404 to press and fix the patient's head.

[0042] During specific use, in order to better fix and support the head when the patient lies flat, when adjusting the head of the radiotherapy patient back and forth, the telescoping of the two symmetrical fourth electric telescopic rods 503 facilitates driving the angle adjustment of the movable connection frame 504 movably connected at the bottom. At the same time, the telescoping of the fifth electric telescopic rod 505 provided facilitates driving the adjustment stretching frame 506. The angle of the rubber pad 507 is adjusted through the adjustment of the adjustment stretching frame 506, which is convenient for adjusting the head of the patient.

[0043] One side of the fixed mounting frame 1 is fixedly connected with a switch panel, and the surface of the switch panel is fixedly connected with a protective layer.
