Description

Radiotherapy body regulation fixing apparatus

This utility model belongs to the clinical treatment assistive device, mainly proposes a kind of tumour patient radiotherapy body regulation fixing apparatus.

The head and neck breast tumor is more common, as the brain cancer, nasopharyngeal carcinoma, carcinoma of maxillary sinus, mouth neoplasm, laryngeal carcinoma, epimere esophageal carcinoma, breast carcinoma or the like, (the surrounding organ function is important owing to its residing special region of anatomy, influence appearance etc.), limited operative treatment, be difficult to implement radical operation, and the medicine chemotherapy, because toxic and side effects is bigger, the relatively poor patient of body constitution be difficult to tolerance and curative effect not very good yet, therefore use clinically and be restricted.Radiotherapy occupies than consequence in the treatment of tumor of head and neck because its side effect is little, curative effect is sure; And in tumour radiotherapy, patient puts whether the position is accurate, and whether repeatability is good, will directly influence therapeutic effect, and the curved-surface structure of body surface will influence the dose distribution of lonizing radiation in addition, and the effect of final influence treatment.In the past clinically for addressing the above problem, usually adopt in patient head or the first-class mode of shoulder bolster with fixation postures, proofread and correct the human body curved surface, but these methods science not there are not certain codes and standards, the error of appearance is bigger.

The purpose of this utility model promptly is to propose a kind of patients with head and neck radiotherapy body regulation fixing apparatus, make it can improve patient and put a degree of accuracy and repeatability, proofread and correct patient's body surface curved surface, improve radiation dose distribution in the patient body, and make it have characteristics simple in structure, that be convenient to operate.

This utility model takes following structural design to finish its invention task: it includes T shape base plate, shoulder is adjusted air bag and head adjustment rack, shoulder is adjusted air bag and is arranged on the base plate position corresponding to shoulder, the head adjustment rack is made of lifter plate and headrest-plate, lifter plate is connected on the base plate, the headrest-plate lower end is hinged on the base plate, two lifting shafts of upper end are positioned at the arcuate groove that sets on the lifter plate, and headrest-plate is provided with headrest.

This utility model device can reach fixedly patient posture, improves pendulum position precision and repeatability, thereby and proofread and correct the purpose that the human body curved surface improves radiation dose distribution in the patient body, it has comparatively simple, the easy to operate and advantage of wide range of application of structural design.

Accompanying drawing 1 is this utility model structural representation.

The embodiment that provides is in conjunction with the accompanying drawings further specified its structure:

As shown in Figure 1, this utility model device includes T shape base plate 2, shoulder is adjusted air bag 1 and head adjustment rack, shoulder is adjusted air bag 1 and is positioned on the base plate 2, corresponding to the human body shoulder position, it is the aerating gasbag structure, adjusts the shoulder height thereby adjust air bag according to the aeration quantity size when adjusting the shoulder height at needs.The head adjustment rack is made of lifter plate 3 and headrest-plate 5, lifter plate 3 is connected on the base plate 2, headrest-plate 5 lower ends are hinged on the base plate 2, two lifting shafts of upper end are positioned at the lifting groove 4 that sets on the lifter plate 3, on the bearing pin and be provided with the fastening nut of using, after headrest-plate 5 was adjusted to proper angle along lifting groove 4, last jack panel made the fixed-site of headrest-plate 5.Headrest-plate 5 is provided with headrest 6, and headrest 6 can be made with having certain elastic plastics, and the arc-shaped protrusions corresponding with cervical region arranged on it.
