Abstract

The invention relates to the technical field of medical instruments, and discloses a vagina source application device. The device comprises a source applicator and a fixing device which are in slidingconnection, the fixing device is further provided with a locking piece used for limiting movement of the source applicator, the source applicator comprises a source application part and an adjustingpart which are connected, scales are arranged on an adjusting part, and a catheter channel penetrating through the source application part and the adjusting part and allowing the catheter connected with the source applicator and a radiotherapy machine to pass through is formed in the source application part and the adjusting part. The fixing device comprises a fixing plate and a fixing belt; wherein the fixing plate is attached to the perineum of a patient, a plurality of fixing grooves are formed in the fixing plate, the fixing belt comprises a first fixing part and a second fixing part, thefirst fixing part and the second fixing part define a fixing waistband, the fixing waistband is annularly arranged on the waist of the patient, a plurality of fixing pull belts are connected to the lower portion of the fixing waistband, and the fixing pull belts correspond to the fixing grooves one to one. According to the technical scheme, the vagina source application device is simple in structure, convenient to use, low in cost, accurate in positioning and easy to position and fix.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a vaginal applicator. Background technique [0002] One of the common treatments for cervical, endometrial, vaginal, and perineal cancers is brachytherapy (also called "brachytherapy") high-dose-rate radiation therapy. Brachytherapy is radiation therapy in which the radiation source is placed in or adjacent to the target tissue (malignancy). During radiotherapy for cancer patients, a radioactive source is catheterized by an afterloader (brachytherapy machine) into the vagina to reach the cervix and, after a predetermined dwell time, back into the afterloader. A major challenge when using cylindrical applicators is the accuracy of the radiation dose received at the target site, which is determined by the relative position of the applicator (source) and the treatment area to surrounding healthy tissues and organs. In order to accurately obtain the relative positions o...
