Abstract

The invention discloses a medical collector of endometrial cells and relates to a medical gynecology medical instrument. The collector is mainly used as an instrument for collecting the endometrial cells at one time, and expanding of a cervical canal is not needed and cross infection can be prevented. The technical scheme is that the medical collector mainly comprises three parts, i.e. a sleeve (1), a core pin (2) and a brush head (3); and the core pin (2) and the brush head (3) are connected with each other, can be separated freely, and are jointly sleeved in the sleeve (1). In order to prevent the sleeve (1) from sliding outwards when the sleeve (1) enters a uterus, a fixing clip (4) is fixed on the lower part of the core pin (2). When the sleeve (1) is needed to be withdrawn, the fixing clip (4) is broken off with hands lightly. In order to master the depth, the surface of the sleeve (1) is labeled with scales (5). The forefront of the brush head (3) is designed to be sphere-shaped , so that the uterus cannot be damaged. The diameter of the sleeve is 3-5mm, so that the cervical canal is not needed to be expanded, and the sleeve can go in or out a cervical orifice freely; and the opening and closing of the brush head is realized by pushing and pulling the sleeve to scrape the endometrial cells.

Description

Medical Endometrical cell collector

Technical field

The present invention relates to a kind of gynecological medical apparatus and instruments, is for gathering endometrial cell, with the disposable Endometrical cell collector tool of diagnosis of endometrial carcinoma.

Technical background

Carcinoma of endometrium claims again carcinoma of uterine body, being primary in endometrium, is one of female genital tract three large common cancers, the health and lives of serious threat middle aged and aged women, along with the application of gonadotherapy and the continuous deterioration of living environment, the onset of endometrial cancer rate is year by year ascendant trend.Early prevention and diagnosis are the keys for the treatment of carcinoma of endometrium, usually gynecological's Endometrial sampling all adopts diagnostic minute erasion to carry out in the hospital, scrape off endometrial tissue, carry out the pathological section diagnosis after the sampling, whole process need scraping internal film tissue, fixing, draw materials, dehydration, transparent, section, dyeing, eight steps of mounting, generally needs just can draw diagnosis report in about five days, consuming time longer, technical sophistication, loaded down with trivial details, cost is higher, and when sampling needs the cervix dilating pipe, painful large, amount of bleeding is many, and patient is difficult for accepting, and gives sometimes patient's injury with painful.And the dilatation and curettage apparatus is hardware, reuses after the sterilization, careless slightly just easily generation cross infection, cause the malpractice insurance accident, for the patient causes the misery of body and mind, along with the gradually enhancing of patient and family members' legal consciousness, might make medical institutions cause unnecessary heavy economic losses.Learning now the popularization of diagnostic techniques along with the popularization and application, particularly cervical liquid-based cells of cytodiagnosis technology, made huge contribution for the prevention of global cervical cancer, is the revolution of cytodiagnosis technology.In view of the cervical cytology diagnostic techniques extensively popularize, we are badly in need of developing another kind of endometrium cell capturing instrument, realize the early screening diagnostic work of Endometrium tumor.

Because this technology is the cell that gathers endometrial surface, rather than endometrial tissue, be difficult for hemorrhage, therefore be hypodynia, less invasive techniques, whole process need brush is got endo cell, fixing, film-making, dyeing, dehydration, six steps of mounting, each step process is consuming time very short, got cytology's report in general 2-3 hour, step is simple, greatly shortened consultation time, for the cytodiagnosis level provides wide application prospect, so a kind of patient misery the same with cervical cytology examination technology of clinician's strong request production is little, be difficult for hemorrhage being easy to and carry out the disposable Endometrical cell collector tool that gynecological haves a medical check-up, the diagnostic techniques of learning by endometrial cell replaces the pathological section of part Curettage to diagnose, reduce unnecessary Curettage in the gynecological, for Endometrium examination technology provides diagnosis basis.

Summary of the invention the objective of the invention is based on above technical background in order to overcome the deficiency of diagnostic curettage, learn a kind of simple to operate that examination invents for promoting endometrial cells, need not the cervix dilating pipe, patient's misery is little, go out insufficiency of blood, be easy to accept, and consultation time is short, prevents the disposable Endometrical cell collector tool of cross infection.

Endometrical cell collector technical scheme of the present invention is: be disposable Endometrical cell collector, comprise sleeve pipe, core bar and three parts of brush, core bar is connected with brush, can freely separate.

The present invention gathers that the brush diameter is less, and casing diameter need not the cervix dilating pipe at 3-5mm, can free in and out cervical orifice, by the push-and-pull to sleeve pipe, realizes opening and closure of brush.

Harvester material therefor of the present invention requires cost low under the prerequisite of ensuring the quality of products, and is harmless healthy, solid, the plastic of flexible.The bristle softness is flexible, and is flexible, and the harvester price economy is reasonable.

Fig. 1 is closure state sketch map of the present invention

Fig. 2 is open mode sketch map of the present invention

Fig. 3 is that endometrium collector enters sketch map in the uterine cavity.

Fig. 4 is that endometrium collector is brushed in uterine cavity and got the cell sketch map.

Specific embodiment the present invention mainly comprises sleeve pipe (1), core bar (2) and brush (3).Core bar (2) is connected 3 with brush) connect, separable, jointly be enclosed within the sleeve pipe (1).Fig. 1 shows collection brush closure state sketch map.Fig. 2 shows cellular collector open mode sketch map.For prevent that sleeve pipe (1) from outwards sliding when entering the uterus, be provided with fixed card (4) in core bar (2) below, when needs are withdrawn from sleeve pipe (1), break gently disconnected fixed card (4) off with the fingers and thumb and get final product.For the ease of grasping the degree of depth, sleeve pipe (1) surface mark scale (5).The forefront of brush (3) designs for ball-shaped, can not cause wound to the uterus.

Use procedure of the present invention: the patient gets calculi position, the doctor expands patient's vagina with vaginal dilator, after seeing the cervix uteri mouth, first the Endometrical cell collector of closure state is slowly sent into (Fig. 3) in the cavity of uterus by the cervix uteri mouth, because sleeve pipe (1) diameter is less, so the cellular collector ratio is easier to such an extent that enter in the cavity of uterus, suitably grasp the degree of depth according to scale (5), when resistance sense is arranged, illustrate to enter in the uterine cavity, arrive at the bottom of the palace, halt, then break disconnected fixed card (4) off with the fingers and thumb, suitably withdraw from sleeve pipe (1), brush (3) bristle is opened, fixed sleeving (1), clockwise rotate the about 3-5 circle of core bar (2) (Fig. 4), can collect the endo cell composition.Then sleeve pipe (1) is pushed in the uterine cavity, brush (3) is closed to be taken in the sleeve pipe (1) together with Cell Component, in uterine cavity, slowly take out the collection brush, sliding sleeve (1), open brush (3), with tweezers brush (3) is taken from core bar (2) and to be put into liquid based cell preservative fluid, or direct smear fixedly send the Cell Lab inspection, atypia and the cell arrangement state of the cellular morphology that gathers on according to smear at Cytology Lab are judged very pernicious.If cell concentration is few, can repeat said process and brush again once, send the Cytology Lab inspection.At last vaginal dilator is taken off, finish whole process.
