Gynecological tumor brachytherapy positioning treatment transfer bed

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a gynecological tumor brachytherapy positioning treatment transfer bed.

Background

With the continuous development of imaging technology and electronic computers, the accuracy requirement of radiotherapy dosage is obviously improved. The remote control and treatment planning system controlled by the computer can make the target region dose distribution more ideal and the curative effect more obvious, thereby the after-loading treatment can be widely applied to the ranges of intracavity, intraductal, intertissue, intraoperative catheter and the like, the range of the after-loading treatment is greatly expanded, and the survival rate of the patient and the time for delaying relapse are obviously improved by the after-loading treatment in combination with external irradiation. Therefore, brachytherapy occupies an irreplaceable position in radiotherapy.

Cervical cancer is a common gynecological tumor, and afterloading treatment is one of the important methods for treating cervical cancer at present. The gynecological afterloading treatment is that the applicator without radioactive source is put into vagina and uterine cavity, and in the control room which is far away from the treatment room and has good protection, the applicator is started to deliver the radioactive source to the container for treatment, and the radioactive source is put back to the source storage tank when the treatment is finished. The patient needs to take the lithotomy position on the gynecological examination bed, the medical personnel put the selected applicator into the treatment position of the patient and fix the applicator, the area to be aligned is aligned through irradiation positioning, the aligned area is displayed on the image processor, and then the afterloading therapeutic apparatus is used for treatment. In the process, the position of the afterloading treatment bed can be moved, the patient is convenient to transfer, the patient must keep the lithotomy position for irradiation positioning and transfer, the patient must keep the posture immovable in the irradiation process by using the brachytherapy machine and must keep the applicator immovable, the thigh of the patient is mostly clamped to keep the lithotomy position for the patient in the current market, the patient is required to be placed on a foot rest for the treatment bed which is used for keeping the lithotomy position for the patient in the current market, the thigh of the patient is lifted by the leg rest and the leg is drooped relative to the leg rest, for the patient, the process is painful and long, the patient is difficult to keep for a long time, the common peroneal nerve is easy to damage after a long time, the blood circulation of the leg is difficult to be numb, the lower limb of the patient is easy to be numb, so the transfer is convenient, and the patient is transferred to the irradiation positioning device for irradiation positioning, and a transfer treatment bed which is beneficial to keeping the lithotomy position of a patient still and improving the comfort of the patient is necessary.
