Abstract

The invention relates to a vaginal orifice fixing device for a source application retaining device. A positioning block is arranged on a guide tube of the source application retaining device and abuts against the cervix orifice. The vaginal orifice fixing device for the source application retaining device comprises a fixing waist strap, fixing tension straps and a fixing clamping head. The fixing clamping head is fixedly installed on the source application retaining device and located at the vaginal orifice. The fixing waist strap is tightened to the waist of a patient and provided with connecting buckles. The fixing tension straps are wound round the fixing clamping head and laterally tension the fixing clamping head towards the intravaginal portion. The fixing tension straps are tightened to the fixing waist strap through the connecting buckles of the fixing waist strap. The vaginal orifice fixing device has the advantages that the structure is simple, practicality is high, the effect is significant, the source application retaining device can be stably fixed to the accurate treatment position, and the situation that in the patient transfer or treatment process, the source application retaining device moves laterally or disengages outwards and deviates from the treatment position due to the body position change, and consequently actual dose distribution is not consistent with planned dose distribution is avoided.

Description

technical field [0001] The invention belongs to gynecological radiotherapy equipment, in particular to a device for fixing the vaginal opening of an applicator resident device. Background technique [0002] At present, known gynecological source resident devices are provided with catheters for radioactive sources to reach lesion locations. During radiotherapy, the resident end of the source applicator is placed in the vagina of the patient, the uterine catheter is inserted into the uterine cavity, and the catheters on both sides of the cervix are placed at the fornix on both sides of the cervix. Supplemented with a fixed bracket to fix the applicator resident device in the vagina. The radiation source reaches the predetermined position through the catheter and stays for a certain period of time to complete the treatment. The source resident device needs to be fixed and kept at the treatment position during patient transfer and radiotherapy. The radiation source is close to...
