The present disclosure relates to the field of medical devices, in particular, to an applicator device assembly for assisting brachytherapy treatment in female genital tract cancers, more particularly for treating vault/vaginal cancer patients. BACKGROUND OF THE INVENTION
Radiotherapy is the treatment for recurrent vaginal vault cancers, and primary vaginal cancers. The first part of treatment is External beam Radiotherapy (with or without Concurrent Chemotherapy) followed by brachytherapy. Interstitial Image Guided Adaptive Brachytherapy (IGABT) in advanced gynaecological cancers is increasingly recognized as the new paradigm worldwide. The core of IGABT is assessment of tumour response during radiotherapy and adaptive tailoring of the brachytherapy boost according to the individual tumour response. Interstitial brachytherapy means placing hollow catheters/needles (through which the radioactive source can pass) within the tumour volume so that the tumors can get a very high conformal curative dose. The disease and normal structures can be contoured and a curable dose can be delivered. It is more important to use IGABT in cases where interstitial needles are used to treat the paravaginal or para cervical tissue, in tumours more than 0.5 cm thickness residual disease after external radiotherapy.
Depending on disease extent, a simple intracavitary/intravaginal application along with/without interstitial needles can be performed. Use of interstitial techniques in vault/vaginal cancer patients with residual disease after External beam radiotherapy (EBRT) gives rewarding results in terms of Local control of disease- and disease-free survival. The prime goal is to treat the residual disease in the vault/vagina delivering a curative dose and least dose to surrounding normal organs by use of interstitial needles to sculpt the dose of brachytherapy.
Various types of applicator devices are known in market, for performing

the IC+IS technique of brachytherapy treatment. One such applicator device is a Martinez perineal interstitial Template (MUPIT) type applicator device. This MUPIT type applicator device includes a multi-component plate-type template unit, and a tandem unit. The template unit is made up of multiple components, which are arranged together, and defines at least one central cylinder and a plurality of catheter routing holes. For performing the interstitial (IS) technique of brachytherapy treatment by the IGABT technique in post operative cancer cervix or cancer vagina treatment, the cylinder is inserted into the vagina of the patient while the bulky template abuts with an external perinium skin of the patient. Thereafter, the cylinder unit is installed and locked into the central hole of the template. Upon such positioning, a plurality of catheters (needles) are routed through the plurality of catheter routing holes of the template, to reach and pierce through the tumor tissue. The template unit is then assembled together with help of other accessories provided. After such positioning, the assembled template is stitched to the external skin of the vagina of the patient, for proper positioning. Thereafter, the radioactive source is exposed through the catheter needles to the tumor tissue, to perform tumor treatment thereon. Notably, the template of such MUPIT type applicator device is made up of multiple components, that are cumbersome to assembled together during the procedure/surgery. Although made of multiple components, its cylinder is fixed in length and cannot be customised according to individual patient's vaginal length. The divergent needles needs to be applied from perinium making them less accurate with increasing distance of disease at the vaginal vault. Furthermore, the plate-type template unit is stitched to the external skin and hangs outside of the vagina of the patient after performing the surgery, which is painful for the patient. The plurality of catheter routing holes in the template unit of such MUPIT type applicator device allows the catheter needles to be routed in a prefixed longitudinal direction and a lateral direction. The catheter needles used in the MUPIT applicator device are often obstructed by bones in

between due to their long path from the template to the target region of the tumor tissue in the cervix. Furthermore, the steel needles are not compatible to CT imaging or MRI imaging making identification of the disease difficult in the planning scan. Overall, it results in cumbersome and time consuming process, more chances of bleeding, increased pain for the patient limits its use in many centers.
Another type of the applicator device is Template Benidorm applicator. Besides having a bulky perineal template which is painful for the patient, it has lesser number of needle options which limits its reach to entirety of the tumor tissue in the cervix of the patient. Moreover, other types of applicator devices such as Venezia applicator and 3D printed customised templates incur higher costs of the treatment and unavailability of such applicator devices limit their use in many centers.
Accordingly, in light of the aforementioned problems, drawbacks and several other inherent shortcomings in the existing arts, there is a need to provide an improved robust applicator device, which requires relatively less effort and time for performing the brachytherapy treatment, while allowing for a greater reach to the tumor tissue developed in the vaginal vault of a patient. There is also a need felt to customise the length of the vaginal cylinder according to patient's size, and make the template/ applicator less bulky to meet patient's compliance and comfort. Further, there is a need to make the template/ applicator MRI (Magnatic resonace imaging) compatible for better treatment plans. OBJECTS OF THE PRESENT INVENTION
This section is provided to introduce certain aspects of the present disclosure in a simplified form that are further described below in the detailed description. This summary is not intended to identify the key features or the scope of the claimed subject matter.
