Description

AUXILIARY DEVICE IN THE DIAGNOSIS OF CERVICAL CANCER

TECHNICAL FIELD

The present invention is related to the technical field of mechanics, electronics, medical devices and more specifically with cancer detection devices, since it provides an auxiliary device in the diagnosis of cervical cancer through the implementation of tools such as a camera that allows visual analysis at the moment, as well as a mechanism that collects samples for a later more complex diagnosis.

BACKGROUND

Cervical cancer, also known as cancer of the cervix of the womb, is a malignant tumor that begins in this area of the body and is more common in women over 30 years of age. It is a preventable and highly curable disease if detected early. It is completely preventable if it is in its early stages of growth. However, there are no organized screening activities in various parts of the world, which accounts for substantially 85% of deaths in developing countries due to this disease.

There may be several factors that explain limitations in the detection of cervical cancer in its early stages, eg, lack of awareness, inadequate infrastructure, limited accessibility to an advanced health care delivery system, and the like. Conventionally, early detection of cervical cancer is achieved by performing regular Pap smears (or cervical smears) which help determine abnormal changes in the cells of the cervix. This involves in vitro examination of the cells under a microscope, which is a tedious process and is also difficult to obtain a desired tissue biopsy. It also results in inconvenience for the patient, as it takes several hours to obtain the desired tissue biopsy for the cancer detection process.

Contrary to in vitro screening tests, visual inspection of the cervix with the application of an acid, eg acetic acid or iodine, has been shown to be a simple and cost-effective approach for the early detection of cervical cancer. However, this approach has its own limitations, for example, lack of qualified or trained personnel, subjective decision of an examiner, inaccurate results when examining with the naked eye, lack of documentation for future purposes, and the like.

Therefore, there is a need for an alternative approach to conventional techniques for cervical cancer detection that provides immediate and accurate results without any requirement for skilled labor.

A search of the state of the art for an auxiliary device in the diagnosis of cervical cancer was carried out, where it was found that different devices have been developed, as mentioned in the United States patent application document number US 2009/082695 ( Al) with publication date on March 26, 2009, with the title "METHODS, SYSTEMS AND DEVICES RELATED TO EXTENSION DEVICES COLPOSCOPIC TYPE VIEWING SYSTEM" which describes a system comprising an imaging and sampling probe sized for easy and comfortable insertion into the vagina without requiring the use of a speculum comprising a handle located proximally and at the least a relatively thin extension that extends distally from the handle, further comprising at least one light emitter that emits illuminating light toward the target tissue, at least one imaging system that detects and images the light of examination emanating from the target tissue, and a biopsy channel configured to transmit to the target tissue a retractable biopsy or a surgical device capable of retractilely contacting the target tissue, even though the devices referred to in the document US 2009/ 082695 (Al) have various utilities located individually in a variety of independent devices such as display on the device itself or externally on a monitor or computer by means of a light emitter and an image sensor. , as well as extraction of samples with biopsy by puncture manually or semi-automated by means of a spring-loaded mechanism, on the other hand, the present invention has a mechanism for obtaining and extracting samples by means of forceps, as well as a system to pour some chemical for better visualization with the camera and light source in the apparatus, which has a screen in the upper external part of it and finally the valve-shaped elements of the apparatus, which can be lengthened to make bigger the vaginal mirror, all this within the same device. Another document found is the United States patent application US 608, 1740 (A) published on June 27, 2000, with the title "METHOD AND APPARATUS FOR OBTAINING IMAGES AND TAKING DISEASED TISSUE SAMPLES" describes a method and apparatus for obtaining images of body tissue using auto fluorescence. The apparatus includes an endoscope having a distal end, a proximal end, and a light processing unit located at the proximal end of the endoscope. The light processing unit accepts light in a spectral region from a light source and directs the light through the endoscope to tissue located at the distal end of the endoscope.

Even though the device referred to in document US 608, 1740 (A) consists of a system for obtaining images of the cervix by autofluorescence of the tissue using a white light emitter and an endoscope as a receiver, which directs the image to a computer and a video receiver, on the other hand, the present invention has a camera and a light source, allowing visualization of the cervix on a screen located in the upper part of the device, it also has a system to pour some type of liquid like Lugol, to better visualize any lesion, it also has a mechanism for cutting and extracting samples, through a sample-taking system that can be manipulated by joystick-type control levers.

There is also the United States patent application document number US 2003/225313 (A), published on December 4, 2003 with the title "VAGINAL SPECULUM WITH SINGLE INSERTABLE LENS COLPOSCOPE", describes a combination of a vaginal speculum with a single lens colposcopy for use in a screening process to detect mucosal abnormalities of cervical intraepithelial neoplasia or invasive cancer, eg, in the vaginal cavity or external parts of the genitalia, as an addition to the screening process of Papanicolaou . The vaginal speculum is identical to a conventional speculum in its shape, dimensions and function and is it differs from a conventional instrument only by having on the inner surface of the lower blade a small projection with a groove to guide a single-loop colposcope. Unlike the present invention, this one has a sampling mechanism and an extractor, a visualization system through a camera, a light source and a screen, as well as a system for pouring Lugol or some other chemical into the area that you want to visualize and analyze.
