Description:FIELD OF THE INVENTION
[001] The present invention relates to the field of medical science, and more particularly, the present invention relates to the intra-cavitary brachytherapy applicator immobilization device.
BACKGROUND FOR THE INVENTION:
[002] The following discussion of the background to the invention is intended to facilitate an understanding of the present invention. However, it should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was published, known, or part of the common general knowledge in any jurisdiction as of the priority date of the application. The details provided herein the background if belongs to any publication is taken only as a reference for describing the problems, in general terminologies or principles or both of science and technology in the associated prior art.
[003] The problem is observed when the cancer patient treated with the intra-cavitary brachytherapy treatment modality. In this application the applicator moves while shifting the patient from OT to CT scan machine room and then to the machine room for treatment. Therefore this device is helpful in fixing the applicator and delivery of treatment accurately to the tumor. The applicator movement in the patient body during shifting makes the difference between the actual and plan doses to the tumor and normal structures of the patient. The applicator tendom move and increases the bladder and rectum doses which affect the outcome of the treatment.
[004] Therefore, in order to fulfill this requirements, there is a need for the Intracavitary brachytherapy applicator immobilization device that overcomes problems prevalent in the prior art.

OBJECTS OF THE INVENTION:
[005] Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows.
[006] The principal object of the present invention is to overcome the disadvantages of the prior art by providing the Intracavitary brachytherapy applicator immobilization device.
[007] An object of the present invention is to provide the Intra-cavitary brachytherapy applicator immobilization device that resolves the patient movement issue in the brachytherapy treatment and increase the accuracy.
[008] Another object of the present invention is to provide the Intracavitary brachytherapy applicator immobilization device, wherein the device is very helpful and reduces the errors in the treatment of cancer patients.
[009] Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

SUMMARY OF THE INVENTION:
[010] The present invention provides Intracavitary brachytherapy applicator immobilization device.
[011] The design of the device is helpful in making the patient position fix with the applicator device implanted into the tumor in cancer patient. The doses to the normal organs and tumor are same as the doses planned in the treatment planning system for the cancer patient. The treatment delivery accuracy may increase and minimize the error. The applicator is placed in or around the tumor inside the patient body in operation theatre. After the application the patient shifted to the strature taking for Computed tomography scan where again patient shifted on the CT scan machine couch and after the scan patient shifted to the treatment room on strature. During shifting of the patient the applicator placed into the body also moves which creates the positional variation of the applicator in the body. To make the applicator fix a device requirement is arises therefore this device design can resolve this movement issue in the brachytherapy treatment and increase the accuracy.
[012] The device is fixed on the CT scan machine and treatment machine couch to restrict the movement of the applicator position. As far as the movement of the applicator in the patient body is concern, this device is very helpful and reduces the errors in the treatment of cancer patients.

BRIEF DESCRIPTION OF DRAWINGS:
[013] Reference will be made to embodiments of the invention, examples of which may be illustrated in accompanying figures. These figures are intended to be illustrative, not limiting. Although the invention is generally described in the context of these embodiments, it should be understood that it is not intended to limit the scope of the invention to these particular embodiments.

DETAILED DESCRIPTION OF DRAWINGS:
[015] While the present invention is described herein by way of example using embodiments and illustrative drawings, those skilled in the art will recognize that the invention is not limited to the embodiments of drawing or drawings described and are not intended to represent the scale of the various components. Further, some components that may form a part of the invention may not be illustrated in certain figures, for ease of illustration, and such omissions do not limit the embodiments outlined in any way. It should be understood that the drawings and the detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the scope of the present invention as defined by the appended claim.
[016] As used throughout this description, the word "may" is used in a permissive sense (i.e. meaning having the potential to), rather than the mandatory sense, (i.e. meaning must). Further, the words "a" or "an" mean "at least one” and the word “plurality” means “one or more” unless otherwise mentioned. Furthermore, the terminology and phraseology used herein are solely used for descriptive purposes and should not be construed as limiting in scope. Language such as "including," "comprising," "having," "containing," or "involving," and variations thereof, is intended to be broad and encompass the subject matter listed thereafter, equivalents, and additional subject matter not recited, and is not intended to exclude other additives, components, integers, or steps. Likewise, the term "comprising" is considered synonymous with the terms "including" or "containing" for applicable legal purposes. Any discussion of documents, acts, materials, devices, articles, and the like are included in the specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all these matters form part of the prior art base or were common general knowledge in the field relevant to the present invention.
[017] In this disclosure, whenever a composition or an element or a group of elements is preceded with the transitional phrase “comprising”, it is understood that we also contemplate the same composition, element, or group of elements with transitional phrases “consisting of”, “consisting”, “selected from the group of consisting of, “including”, or “is” preceding the recitation of the composition, element or group of elements and vice versa.
[018] The present invention is described hereinafter by various embodiments with reference to the accompanying drawing, wherein reference numerals used in the accompanying drawing correspond to the like elements throughout the description. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein.

[019] The present invention provides Intra-cavitary brachytherapy applicator immobilization device.
[020] The design of the device is helpful in making the patient position fix with the applicator device implanted into the tumor in cancer patient. The doses to the normal organs and tumor are same as the doses planned in the treatment planning system for the cancer patient. The treatment delivery accuracy may increase and minimize the error. The applicator is placed in or around the tumor inside the patient body in operation theatre. After the application the patient shifted to the strature taking for Computed tomography scan where again patient shifted on the CT scan machine couch and after the scan patient shifted to the treatment room on strature. During shifting of the patient the applicator placed into the body also moves which creates the positional variation of the applicator in the body. To make the applicator fix a device requirement is arises therefore this device design can resolve this movement issue in the brachytherapy treatment and increase the accuracy.
