[0002] Cervical lesion is one of the most common diseases of women, and the heavy one can develop into cervical cancer. Cervical cancer is one of the three most common malignant tumors of female reproductive system, and the number of new cervical cancer cases is large every year. In recent years, the incidence and mortality of cervical cancer have increased, and the trend of younger patients is serious harm to the life and health of women.

[0003] The evolution of cervical cancer is usually a continuous development process from cervical intraepithelial lesion to carcinoma in situ to early invasive carcinoma to metastatic invasive carcinoma. CIN is a hyperplastic lesion formed by atypical hyperplasia or abnormal differentiation of cervical epithelial cells, but has not yet infiltrated, and is divided into mild atypical hyperplasia (CIN1), moderate atypical hyperplasia (CIN2) and severe atypical hyperplasia (CIN3), among which CIN2 and CIN3 belong to high-grade squamous intraepithelial lesions. Generally, CIN1 develops into invasive carcinoma for about 8-10 years, carcinoma in situ develops into invasive carcinoma for about 3-4 years, and the 5-year survival rate of clinical stage of cervical cancer can reach 95.4%, and the survival rate of CIN2 period is reduced to 75.8%. Therefore, it is of great significance to reduce the incidence and mortality of cervical cancer to do a good job in the examination of cervical precancerous lesions of women, especially cervical high-grade lesions (CIN2, CIN3, cervical cancer), make an early diagnosis, and effectively prevent and treat.

[0004] At present, the sampling of cervical tissue mostly uses biopsy forceps, and the existing biopsy forceps head is not sharp, which makes it difficult to accurately position the sampling of cervical tissue, and for the tissue sampled at multiple points, it is easy to cause confusion, which affects the accuracy of subsequent biopsy examination.

[0024] In order to make the purpose, technical scheme and advantages of the utility model embodiments clearer, the technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are part of the utility model embodiments, rather than all the embodiments. The components of the utility model embodiments described and shown in the drawings can be arranged and designed in various different configurations.

[0025] In the description of the utility model embodiments, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the utility model product is used, which is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" and the like are only used for differentiation in description and cannot be understood as indicating or implying relative importance.

[0026] In addition, if the terms "horizontal", "vertical", "overhanging" and the like are used, they do not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0027] In the description of the utility model embodiments, "a plurality of" represents at least 2.

[0028] In the description of the utility model embodiments, it should also be noted that unless otherwise explicitly specified and limited, if the terms "arrangement", "installation", "connection", "connection" are used, they should be understood broadly, for example, they can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] In combination with the drawings, a cervical lesion positioning device comprises a positioning needle 1 and a sleeve 2;

[0030] The sleeve 2 is movably sleeved on the positioning needle 1, specifically, the positioning needle 1 is movably sleeved in the sleeve 2, and the positioning needle can move along the sleeve axis direction.

[0031] In the initial state, both ends of the positioning needle 1 extend to the outside of both ends of the sleeve 2, and the penetration of the sleeve 2 is positioned by the penetration of the tip of the needle body 1 in the suspected lesion area of the cervix, and the penetration of the sleeve 2 into the suspected lesion area of the cervix can be driven by the penetration of the positioning needle 1, and after the sleeve 2 is penetrated into the cervical tissue, the positioning needle 1 can be pulled out of the sleeve 2.
