Overturning type neck tumor radiotherapy device

Abstract

The invention relates to an overturning type neck tumor radiotherapy device which comprises a bed body, on which a patient with a tumor can lay for radiotherapy, a radiotherapy component used for performing local radiotherapy to a neck of the patient and a head supporting plate capable of changing a posture of a head of the patient; the radiotherapy component comprises a guide rail of a semi-ringstructure and a radiotherapy irradiator; the radiotherapy irradiator is slidably arranged on the guide rail; the two ends of the guide rail are hinged to the bed body through rotating shafts respectively; the guide rail can be overturned to the position below the bed body from the position above the bed body; the head supporting plate is hinged to the head end of the bed body through a rotating shaft and can overturn upward/downward; and the bed body is provided with an irradiation hole, through which the radiotherapy irradiator irradiates a tumor part from the lower side of the bed body. Theneck tumor radiotherapy device provided by the invention has the overturning type guide rail, the radiotherapy irradiator can slide on the guide rail, the irradiation position can be adjusted flexibly, the guide rail can be overturned to the position below the bed body from the position above the bed body, and radiation treatment can be performed on a front neck and a rear neck of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a flip-type radiotherapy device for neck tumors. Background technique [0002] Radiation therapy is one of the main means of cancer treatment at present. Different from surgical treatment, radiation therapy uses radiation to kill cancer cells, while the shape and function of normal tissues and organs can often be preserved. Therefore, radiotherapy is also called cancer without a knife. tumor resection. Such as early vocal cord cancer, radiation therapy can not only cure the cancer, but also save the patient from laryngectomy and preserve the patient's vocal function. [0003] Neck treatment is an integral part of head and neck cancer treatment, which not only refers to the presence of definite neck metastases, but also includes No patients with no obvious enlarged lymph nodes. After pathological examination of selective neck dissection specimens of head and neck cancer ...

AI Technical Summary

Problems solved by technology

However, the mobile structure of the radiotherapy mechanism is relatively complicated, and only the upper part has a radiotherapy device, so radiotherapy for the back of the neck cannot be performed. If a radiotherapy device is installed below, the cost and structural complexity will be greatly increased
