Description

Gynecological cervical sampler

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a gynecological cervical sampler.

Background

With the popularization of cervical cancer screening, the diagnosis rate of cervical cancer and precancerous lesions is gradually increased. According to the current diagnosis and treatment standards, the diagnosis and treatment of cervical cancer and precancerous lesions depends on pathological examination of cervical biopsy tissue. The anatomy structure of human cervical tissue is similar to a hollow cylinder, the upper end is connected with the uterus and is positioned in the pelvic cavity, and the lower end is exposed in the vagina and can be observed after the vagina is dilated. The cervical surface exposed to the vagina is not planar and has a great individual variation, and the cervical surface of women of different ages has different textures, hardness and histological structures. Pathological examination of cervical tissue requires that the taken tissue sample reach a certain width and depth, and that the taken tissue has integrity, so as to facilitate the observation and diagnosis of the tissue in sections. Lesions of the cervix may occur in any area of the cervix, may occur on the surface of the cervix, may occur in the cervical canal, and may also occur on the slope of the junction of the surface of the cervix and the cervical canal. Due to individual differences of human cervix and diversity of cervical lesion positions, a cervical sampler is urgently needed, biopsy sampling can be carried out on tissues of cervix with different textures and different region positions, positioning is required to be accurate, sampling is convenient, cross contamination is avoided, the purpose of improving cervical disease diagnosis accuracy is achieved, and the cervical sampler is suitable for being widely applied to hospitals of all levels.

Application number CN101495044B discloses a cell sampling brush comprising an operation handle, one end of the operation handle is provided with a first part in the form of an ectocervical sampling brush and a second part in the form of an endocervical sampling scraper, the second part is in a strip shape, and a plurality of bristles are uniformly distributed around the circumference and the length direction of the second part; the second part is stretched into the cervix, rotated, and then the second part is withdrawn, thus completing the sampling of cells in the cervix.

However, when detecting a disease condition, the infection depth of virus or bacteria in the cervix is one of indexes for judging the disease condition, but because the conventional sampling brush usually stretches into the cervix for sampling, cells adhered to different parts in the cervix are adhered to the sampling brush, and the cervix parts with different depths cannot be sampled, the virus or bacteria in the cells on the sampling brush cannot be accurately judged to be at the cervical opening or deep in the cervix, which is not beneficial to the judgment of a doctor on the disease condition.

The beneficial effects are that: when it is required to check whether some solid particles of blood clot exist in the cervix of the patient, the substances such as body fluid in the cervix of the patient can be sucked into the shell from the needle head through the negative pressure of the piston by slightly pushing and pulling the push rod.

Further, the needle is provided with a rubber cover which is detachably connected with the needle.

The beneficial effects are that: through being provided with the rubber lid, can protect the syringe needle, prevent that the syringe needle from polluting.

Further, a holding groove is formed in the handle.

The beneficial effects are that: through being provided with the groove of holding, medical personnel can put the finger in the groove of holding, increases the stability when operating.

Further, scale marks are arranged on the push rod.

The beneficial effects are that: through being provided with the scale mark, medical personnel can judge the suction volume through observing the scale mark when sucking the intracervical body fluid.
