Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an adjustable T-shaped shoe. Background Art
[0002] Radiotherapy is an important part of the comprehensive treatment model for gynecological malignancies (cervical cancer and endometrial cancer, etc.). Gynecological tumor patients need to hold their urine to fill their bladders before radiotherapy, which is stressful and stressful. Before treatment, they must first undergo a cone beam CT (CBCT) scan to verify the position. After the scan is completed, plus the normal radiotherapy process, the entire time may be 20-30 minutes, which is bound to reduce the patient's comfort. In addition, as the number of radiotherapy sessions increases, radiation cystitis and proctitis will also occur. Side effects such as frequent urination, urinary urgency, dysuria, abdominal pain, and diarrhea will further reduce the patient's comfort during treatment. The comfort and cooperation of treatment will also decrease, and the difficulty of maintaining body position during radiotherapy will increase accordingly. During radiotherapy, how to keep the body position consistent with the simulation positioning is the key to achieving precise radiotherapy.
[0003] At present, the mainstream method of maintaining body position during pelvic radiotherapy for gynecological tumors is thermoplastic body membrane. Although it can effectively prevent the left and right displacement of the patient's body during radiotherapy, it cannot limit the rotational displacement of the pelvis, especially the bilateral joints. If the patient's pelvis is rotated during treatment, the accuracy of the treatment will be greatly reduced, especially for patients with pelvic metastatic lymph nodes, which will cause off-target lymph node radiotherapy and greatly affect the treatment effect. In addition, after rotational displacement occurs, the anatomical position of normal pelvic organs and bilateral femoral heads will also change, deviating from the positioning CT, and increasing the risk of radiotherapy for normal organs.
[0004] Therefore, how to improve the accuracy of radiotherapy positioning and ensure the repeatability of body position has become an urgent problem to be solved. Utility Model Content
