Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical auxiliary instrument, in particular to a vaginal length scale for radiotherapy. BACKGROUND

[0002] Cervical cancer is a disease with high morbidity and mortality in female reproductive system tumors, wherein radiotherapy is an important part of cervical cancer treatment. After seeing a patient, a gynecological examination will be performed by a radiotherapy doctor, and the healing condition of the postoperative vaginal stump will be checked by vaginal expansion. The length of the postoperative vaginal stump is measured by digital examination. Whether the whole vagina (or part of the vagina) needs to be included in the radiotherapy range is determined in combination with preoperative examination and postoperative pathology. In the CT positioning process of radiotherapy, the doctor usually places a 1ML syringe (without needle) in the patient's vagina, pushes it in, and pastes a marker at the patient's urethral orifice to show the length of the vaginal stump. This helps the radiotherapy doctor determine the irradiation range during the subsequent development of the radiotherapy plan. Because the front end of the syringe has segments and protrusions, the patient feels nervous and uncomfortable after insertion. The urethral orifice marker is usually not pasted at one time due to secretions, and multiple adjustments are required, which causes discomfort to the patient. Some hospitals use cotton balls to mark during this process. The cotton ball is large in size and difficult to remove, and the marker is not obvious on the CT image.

[0003] Therefore, there are a vaginal depth measuring scale disclosed in the utility model patent with publication number CN214048821U and a vaginal depth measuring device disclosed in the utility model patent with publication number CN2559315Y, which assist doctors in measuring the length of the patient's vagina.
