Abstract

The utility model relates to an exfoliated endometrium cell sampler which includes a handle; one end of the handle is provided with a brush handle which forms an integral structure with the handle; the diameter of the brush holder is less than that of the handle; densely covered brush hair is fixed on the outer wall of the outer section of the brush holder. Such exfoliated endometrium cell sampler not only is an instrument with small trauma to the patients and basically no pain which is acceptable to the patients, but also can brush the lesion exfoliated cells representing the status of the whole endometrium in the early period of lesion when the patients show clinical symptoms to make folium smear; microscopic examination after dyeing can greatly improve the detection rate of the endometrial cancer and the precancerous lesion, so that the patients can diagnose and cure their diseases in the early period, so as to prevent endometrial cancer.

Description

Endometrium exfoliative cyte sampler

Technical field

This utility model relates to a kind of cell sampler, the Endometrium exfoliative cyte sampler of more specifically saying so.

Background technology

Carcinoma of endometrium is one of the malignant tumor of the reproductive system of the vast female body health of serious harm.For a long time, for early diagnosis carcinoma of endometrium and precancerous lesion, still there are not effective means and method.At present, the diagnostic method of Cai Yonging mainly contains ultrasonic diagnosis and scrapes and gets endometrial tissue and carry out check pathological section clinically, the former deficiency is low to the recall rate of early diagnosis carcinoma of endometrium and precancerous lesion, be easy to cause omission, the latter's deficiency is: 1, when sampling, must scrape and get enough big endometrial tissue and just can carry out check pathological section, cause wound, bring misery to the patient to the patient; 2, omission also appears in the limitation at position easily because dilatation and curettage is drawn materials; The position is accurate even if 3 dilatation and curettage are drawn materials, and omission do not occur, and the pathological changes of this moment is quite serious, has missed the treatment good opportunity.

Summary of the invention

The purpose of this utility model provides the endometrium exfoliative cyte sampler that a kind of wound to the patient is little, improve recall rate.

In order to realize above-mentioned purpose, the endometrium exfoliative cyte sampler that is provided comprises handle, and its construction features is that the end at handle is provided with handle and constitutes an integrally-built brush holder, the diameter of brush holder is less than the diameter of handle, is connected with densely covered bristle on the outer wall of the outer section of brush holder.

In order to make bristle can get the endometrium exfoliative cyte reliably and to be convenient to operation, the endometrium exfoliative cyte sampler that is provided, also comprise handle jacket and constitute an integrally-built bristle overcoat with handle jacket, gap between handle and the handle jacket is an air flue, being provided with an end in the air flue is fixed on the handle outer wall, the slide block that the other end contacts and can slide and rotate under external force with the inwall of handle jacket, slide block is spaced apart on the handle outer wall, brush holder extend into from the handle jacket inner chamber in the bristle overcoat inner chamber, makes bristle be arranged in bristle overcoat inner chamber when static state.

The using method of endometrium exfoliative cyte sampler provided by the utility model is: push away before 1, holding handle jacket, the bristle overcoat is inserted into the Cervical bottom of patient after the sterilization; 2, with pushing handle before the hands, drive the brush holder reach, bristle is stretched out in the bristle overcoat and enter in the cavity of uterus; 3, turning handle 3-5 week drives bristle and rotates in the cavity of uterus inter-sync, obtains the cell tissue of endometrium under coming off with bristle; 4, outside pull handle is extracted out from the inner chamber of handle jacket until the bristle that has the endometrium exfoliative cyte; 5, take out handle jacket and bristle overcoat; 6, the endometrium exfoliative cyte that obtain are made thin smear, dyed back microscopy is to determine its pathological change.

Learn by above narration, endometrium exfoliative cyte sampler provided by the utility model, still not a kind of apparatus of, basic no pain little to patient's wound, the patient is acceptant, and it is early stage to begin to show the pathological changes of clinical symptoms the patient, brush is got the pathological changes exfoliative cyte with the whole endometrium present situation of representative, make thin smear, dyeing back microscopy, improved the recall rate of carcinoma of endometrium and precancerous lesion greatly, make the patient can early diagnosis, the early treatment, the generation of prevention carcinoma of endometrium.

Description of drawings

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, wherein:

Fig. 1 is the structural representation of endometrium exfoliative cyte sampler when static state;

Fig. 2 is the structural representation of endometrium exfoliative cyte sampler when sampling;

Fig. 3 is the A-A cutaway view of Fig. 1.

Among the figure: 1 is handle, and 2 is brush holder, and 3 is bristle, and 4 is handle jacket, and 5 is the bristle overcoat, and 6 is air flue, and 7 is slide block.

The specific embodiment

With reference to accompanying drawing, the described endometrium exfoliative cyte of embodiment sampler, comprise handle 1, end at handle 1 is provided with and handle 1 formation one integrally-built brush holder 2, the diameter of brush holder 2 is less than the diameter of handle 1, be connected with densely covered bristle 3 on the outer wall of brush holder 2 outer sections, the inner segment of handle 1 and brush holder 2 is arranged in the inner chamber of handle jacket 4, outer section of brush holder 2 and bristle 3 are arranged in the inner chamber of bristle overcoat 5, handle jacket 4 and bristle overcoat 5 constitute an overall structure, gap between handle 1 and the handle jacket 4 is an air flue 6, being provided with an end in the air flue 6 is fixed on handle 1 outer wall, the slide block 7 that the other end contacts and can slide and rotate under external force with the inwall of handle jacket 4, the quantity of slide block 7 is four, spaced apart on handle outer wall 4.
