Detailed Description

In order that those skilled in the art will better understand the present utility model, the following technical scheme of the present utility model will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the endometrial cell collector comprises an inner rod 1 and an outer tube 11 sleeved on the inner rod 1, wherein the upper end of the inner rod 1 is provided with a collecting ring which can be folded in the outer tube 11, the collecting ring comprises two symmetrically arranged collecting petals 12, a plurality of scraping blades are fixedly arranged on one side, close to each other, of the two collecting petals 12, each scraping blade comprises a connecting section 13 and an extending section 14, the connecting sections 13 are fixedly connected with the collecting petals 12, the extending sections 14 are obliquely arranged on one side, far away from the collecting petals 12, of the connecting ends 13, the thickness of the connecting sections 13 is larger than that of the extending sections 14, and limit balls 15 are jointly arranged on the upper ends of the two collecting petals 12.

In the original state, the two collection petals 12 are mutually folded and accommodated in the outer tube 11, and in the state that the two collection petals 12 are mutually folded, the vertexes of the extension sections 14 of the plurality of scraping blades at the left side and the right side are mutually contacted, then the extension sections 14 are bent, the vertexes of the extension sections 14 are abutted against the inner sides of the collection petals 12 again, as the thickness of the connecting section 13 is larger than that of the extension sections 14, in the state that the two collection petals 12 are folded, the vertexes of the extension sections 14 are abutted against the inner walls of the corresponding collection petals 12 which are connected, then the space between the collection petals 12 and the scraping blades in the bent state is an accommodating space for accommodating endometrial cells, when the endometrial cells are collected, the outer tube 11 is inserted into the cervix, the limiting ball 15 is in the circular arc state, the insertion into the cervix is more convenient, discomfort of a patient is not caused, after the outer tube 11 is inserted into the cervical position of a patient, a medical staff holds the outer tube 11 with one hand and pushes the inner rod 11 with the other hand to push out the two collection petals 12, the two collection petals 12 are mutually far away from each other to be in an open state after being pushed out of the outer tube 11, then the inner rod 1 can be rotated to enable the two collection petals 12 to be rotated into 8 to 10 circles, the two collection petals 12 are fully contacted with endometrial tissues, mucous membrane layers and basal layers, after the cell collection is finished, the inner rod 1 is pulled back again to enable the inner rod 1 to drive the two collection petals 12 to be returned to the inner tube 11 and restore to the original state, thus the two collection petals 12 scrape endometrial cells into the two collection petals 12, the sharp parts of scraping blades can be prevented from being contacted with the inner wall of the uterus of the patient to cause scratch, after the two collection petals 12 are folded, the left scraping blades and the right scraping blades restore to the original state, the cells can be wrapped in the accommodating space, the collection and packaging effects are good, the restriction effect is achieved, the cell shedding is avoided, finally, the collector is pulled away from the uterine cavity of the patient, the operation is simple, and the endometrial cell collection work of the patient is completed.

The scraping blades arranged on one side of the two collection flaps 12 close to each other are not less than three; the three or more scraping blades can meet the use requirement, can be adjusted according to the production and detection requirements, and are convenient to use.

The number of the collection petals 12 arranged at the upper end of the inner rod 1 is not less than two; the minimum of two collection lobes 12 can be used to meet the need, and if desired, the number of collection lobes 12 can be increased to more than two.

The lower end of the inner rod 1 is provided with a push rod 16; the push rod is used for pushing and pulling the inner rod 1, so that the operation is more convenient.
