Description

A tumor radiotherapy bed

technical field

The utility model relates to a radiotherapy positioning device, in particular to a tumor radiotherapy bed.

Background technique

Stereotactic radiotherapy uses a special stereotaxic device, scans and positions through CT or MΓI, and uses the principle of focusing to concentrate the radiation of each irradiation field or arc to the tumor area (target area), while the normal tissues around the target area receive doses. rare. According to tumor characteristics, single stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) can be performed. SRS is more common in head γ-knife treatment, and is used for the treatment of intracranial arteriovenous malformations, brain function diseases, brain metastases, meningiomas, acoustic neuromas, craniopharyngiomas, pituitary tumors, and gliomas. SRT is more common in the X-knife of the head and body and the γ-knife of the body. It can be used not only for intracranial lesions, but also for the treatment of lung cancer, liver cancer, pancreatic cancer, adrenal gland tumors, and abdominal and pelvic tumors. SRS and SRT can be used alone or in combination with other radiation therapies.

But, because most of existing radiotherapy positioning frames are partial basically, as: head and neck radiotherapy fixing frame, chest radiotherapy positioning frame etc., therefore, it is difficult to reset consistently in each radiotherapy in clinical work. Each patient is irradiated about 30 times in one course of radiation therapy. During each irradiation, the change of the treatment position causes the displacement of the irradiation, which will cause radiation damage to normal tissues and radiation omission of tumor tissues. Chinese patent CN202538186U discloses a multifunctional radiotherapy bed, which is beneficial to prevent radiation from damaging normal tissue cells, but the positioning effect is poor and the installation process is complicated, which is not conducive to actual operation.

Utility model content

The utility model can not only prevent radiation from harming normal tissue cells, but also accurately locate and avoid radiation omission of tumor tissues, and can realize rapid installation and adjustment, simplify operation, and improve the working efficiency of medical staff.

In order to achieve the above object, the utility model provides a tumor radiotherapy bed, which includes bed legs and a bed board. There are two mutually symmetrical chutes penetrating the bed board on both sides of the bed board. Cover connection; the diameter of the bolt thread matches the width of the chute, and is clamped and fixed by two matching nuts with the bed board; the center of the bed board is provided with an inwardly recessed back positioning groove, and the size of the back positioning groove is the same as that of the positioning rod Matched, the positioning rod is connected and fixed with the patient's limbs through shoulder straps and abdominal belts; the top of the bed board is provided with an inwardly recessed head positioning groove, and mounting holes are provided around the head positioning groove; Corresponding to the position of the upper arm of the human body, an inwardly recessed support arm positioning groove is arranged below the positioning groove.

Further, 2 to 4 air-permeable grids are arranged on both sides of the positioning groove on the back of the bed board, which reduces the weight of the bed board while meeting the requirements of comfort and ventilation.

Before use, the lead cover is removed, and the patient binds the positioning rod to the spine through the shoulder strap and abdominal belt, and lies on the radiotherapy bed so that the positioning rod is located in the positioning groove of the back; the two arms are placed in the positioning groove of the support arm; according to the patient Configure the appropriate number of lead masks for the body shape and radiotherapy site, rotate the matching nuts on the bolts, adjust the height of the fixed lead masks through the distance between the head of the bolts and the bed board, and adjust the position of the fixed lead masks by sliding the bolts in the chute to protect normal tissues Then adjust the position of the head, connect the head positioner with the installation hole, fix it on the radiotherapy bed, and perform radiotherapy.

The beneficial effects of the utility model are: 1. It can block the damage of radiation to normal tissue cells; 2. It can accurately locate and avoid the radiation omission of tumor tissue; 3. It can realize rapid installation and adjustment, simplify operation, and improve the work of medical staff. efficiency.
