Description

Penis cancer radiotherapy fixing device

Technical Field

The utility model relates to the field of medical equipment, particularly, relate to a penis cancer radiotherapy fixing device.

Background

Penile cancer is a malignant tumor originating in the glans penis, coronary sulcus and inner lining mucosa of the foreskin as well as the skin of the penis. Is the most common malignant tumor of penis, and accounts for more than 90% of the tumor of penis. The most common type of pathology is squamous cell carcinoma of the penis, accounting for about 95% of carcinoma of the penis. Therefore, penile cancer is becoming almost a synonym for squamous cell carcinoma of the penis, rendering the presence of other types of penile cancer overlooked. Penile cancer is a rare malignant tumor, and radiotherapy is one of the main treatment methods of the penile cancer, so that the form and the function of the penis of a patient can be kept as much as possible, and the life quality of the patient can be improved. The parts for the radiotherapy of the penile cancer generally comprise penis, inguinal lymph node and the like, the activity of the target area is high, and the testis needs to be protected. How to effectively fix the target area, protect normal organs, ensure the repeatability of the positioning of the patient and the comfort of the patient, and improve the gain ratio of treatment is very important. At present, the position fixing common method for the penis cancer radiotherapy adopts a prone position, the legs are spread, the penis is straightened and is immersed into water or paraffin, and the position fixing radiotherapy is carried out. The method has the disadvantages of poor repeatability, compliance and comfort of the radiotherapy body position of a patient, poor dose distribution at the root of the penis, ineffective protection of the testis, and difficulty in ensuring the reliability of radiotherapy and the gain ratio of treatment. Current fixing device for penis cancer radiotherapy generally adopts the direct centre gripping of centre gripping subassembly and patient's penis, but because patient's penis is rich in spongy tissue, changes the size constantly easily at the radiotherapy in-process, and the centre gripping subassembly probably breaks away from in the centre gripping subassembly because the size change of penis when the radiotherapy after tentatively adjusting centre gripping patient's penis, leads to patient distending pain or penis.
