Description

Human body fixing and supporting device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a human fixed bolster device.

Background

During some treatments or examinations, it is desirable to immobilize a patient in a sitting or standing position, and in some cases even rotate the immobilized patient, such as proton, heavy ion radiation therapy.

Radiotherapy plays an important role in the field of tumor therapy as one of conventional means of tumor therapy. At present, photon and electron beam radiotherapy based on linear accelerator technology is most widely used in radiotherapy, proton and heavy ion ray radiotherapy based on synchronous or cyclotron technology is also gradually applied, and research shows that the effect of proton and heavy ion radiotherapy is superior to that of photon and electron radiotherapy, and especially the toxic side effect and adverse reaction caused by radiotherapy are obviously less than those of the latter.

During the radiotherapy process based on the linear accelerator radiotherapy technology, a patient generally lies on a treatment bed, and the part where the tumor is located is fixed by using a positioning accessory such as a thermoplastic net or a thermoplastic film. Then, multi-angle fixed field or continuous angle rotary irradiation around the target area is realized by rotating the accelerator frame, so that the aims of concentrating the dose on the target area and reducing the receiving capacity of peripheral organs at risk are fulfilled; in addition, image-guided radiotherapy for a patient using on-board Cone Beam CT (Cone Beam CT, CBCT) of a linear accelerator is an effective method for improving the positioning accuracy. The premise of realizing the functions is that a rack of the rotary accelerator is needed, the weight of the rack of the existing linear accelerator is more than 1 ton, and the mechanical rotation is relatively easy to realize. The gantry weight of the synchrotron or cyclotron required by proton and heavy ion radiotherapy reaches hundreds of tons, and the precise rotation of the gantry by the current technology is very complex and difficult and extremely high in cost. For this reason, this type of accelerator has a beam irradiation mode using a gantry fixed. Under the supporting and fixing mode of the traditional treatment bed, because the treatment bed only supports the horizontal state, under the condition that the machine frame cannot rotate, only a few fixed angles installed and fixed in the machine room can be selected for fixed field irradiation, and the rotary field irradiation and CBCT image guided radiotherapy technology cannot be directly applied, so that the irradiation effect is greatly reduced, and the curative effect of a patient is seriously influenced.
