Description

A cervical lesion detector and its detection method

technical field

The invention belongs to the technical field of medical equipment, and in particular relates to a cervical lesion detector and a method for detecting it.

Background technique

Cervical cancer is the second largest gynecological tumor in the world. There are about 131,500 new cases in my country every year, accounting for 1/4 of the world's total. More than 50,000 women die of cervical cancer in my country every year. According to the sixth census data of the National Bureau of Statistics of my country, there are about 430 million women aged 21 to 65 in China. Since 2009, my country has started to implement the cervical cancer screening project for rural women and so far, only 60 million have been completed. The main reason is that the current examination methods are expensive, time-consuming, complicated to operate, very technically demanding, and rely on pathologists.

The methods currently used for cervical lesion examination include TCT examination, HPV examination, colposcopy and biopsy. First of all, the cost of TCT examination is high, the result is slow, and the accuracy rate cannot be guaranteed. At the same time, it depends on pathologists. In my country, pathologists are quite scarce and cannot meet the demand; secondly, the price of HPV examination is more expensive, and the time to produce results is slower, and the test is positive. The rate is too high, but the absolute majority of HPV virus infections are transient, and more than 90% can be cleared by autoimmunity, so HPV inspection is more likely to cause psychological burden on patients and the referral rate of colposcopy; the cost of colposcopy is relatively low It is more expensive, and the operation is complicated, time-consuming, and professional requirements are high. The patient is uncomfortable during the examination and relies on colposcopy equipment (more expensive). A biopsy is the removal of a piece of human tissue for examination and is usually used in qualitative diagnosis.

Therefore, there are technical problems to be solved urgently in this field, and a more reasonable technical solution needs to be proposed to solve the above technical problems.

Contents of the invention

The purpose of the present invention is to provide a cervical lesion detector and its detection method, aiming to use the characteristics of abnormal blood vessel proliferation and increased vascular fragility in cervical lesions, and to discover the lesions by exposing the abnormal blood vessels to bleeding by pressing and rubbing the cervix.
