Abstract

The utility model belongs to the field of medical instruments, in particular to an endometrial sampler, which comprises a sampling sleeve, a mandrel, a piston and a handle. Two ends of the mandrel are connected with the piston and the handle respectively, the piston and the mandrel are jointly mounted in the sampling sleeve, a sampling opening is arranged at the head of the sampling sleeve, and a limit notch is arranged at the tail end of the sampling sleeve. The endometrial sampler is characterized in that a rough surface is arranged at the front end of the sampling sleeve, and the head of the sampling sleeve is a smooth hemispherical tip. The endometrial sampler can be used for extracting liquid tissues in a uterus, and endometrial mucosal cells can be extracted by the aid of the rough surface at the front end of the sampling sleeve, so that the endometrial sampler is simple and convenient to operate, makes no pain to a patient, and meets the requirement of noninvasiveness in the field of existing endometrial sampling. The head of the sampling sleeve is designed into a smooth hemispherical shape, so that pain of the patient can be relieved to the greatest extent.

Description

The endometrium sampler
Technical field
This utility model relates to an Endometrium sampler, belongs to medical instruments field.
Background technology
Carcinoma of endometrium is one of female genital tract three big malignant tumor, its sickness rate has accounted for first of gynecologic malignant tumor in the European and American areas, in recent years, because China's rapid economic development, life style and the change of dietary structure, the factors such as extensive use of hormonotherapy, the sickness rate of carcinoma of endometrium obviously rises.Clinically, the diagnosis of carcinoma of endometrium mainly is to obtain the endometrium specimen by biopsy endometrial curette, but the method is a kind of unrepeatable method of making a definite diagnosis that wound is arranged, and brings huge misery to the patient, and has 80% final detection result negative approximately among these examined persons.So a kind of noninvasive screening technique that carries out the uterus tumor prevention of domestic demands at present.In recent years, domestic existing much about the patent of endometrium sampler, mainly be to realize by following dual mode, a kind of is that sacculus formula or Brush type are gathered the mucosa cell, another kind is to utilize negative pressure suction type collection liquid tissue, exists sampling not cause the inaccurate phenomenon of testing result entirely.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: not only can gather the mucosa cell simultaneously but also the endometrium sampler of collection liquid tissue but provide a kind of, compact conformation, simple to operate, safe and reliable and patient's no pain.
The technical scheme that its technical problem that solves this utility model adopts is: an Endometrium sampler, comprise drive pipe, core bar, piston and handle, the core bar two ends are connected with handle with piston respectively, piston and core bar are assemblied in the drive pipe jointly, the head of drive pipe has sample tap, afterbody is provided with limited impression, it is characterized in that: the drive pipe front end is provided with rough surface, and the head of drive pipe is smooth hemispherical tip.
Can gather liquid tissue in the uterus by drive pipe, and because the drive pipe front end has the rough surface of a segment distance, this rough surface can extract easily to endometrial mucosa cell, simple to operate, make patient's no pain, satisfied the noninvasive demand in present endometrium sampling field, in addition, with the head design of drive pipe is smooth hemispherical, also can alleviate patient's misery to a greater extent.Usually all be provided with scale marker on the drive pipe, be convenient to judge that the endometrium sampler enters the degree of depth in uterus.
Operation principle and process:
1) before the use, with the angle that head-bent becomes and uterus anatomy matches of endometrium sampler;
2) thorough disinfection pudendum, vagina and cervix uteri;
3) take out the endometrium sampler from packaging bag, be inserted into the depths, uterus to the bottom by cervix uteri gently, the scale on the drive pipe can help the clinician that insertion depth is judged;
4) the pulling handle is drawn back piston by core bar, thereby produce negative pressure tissue fluid is sucked drive pipe, pumpback piston in front and back rotates the endometrium sampler simultaneously for several times with more fully sampling, draw back the endometrium sampler after the Uterine mucosa fragment appears in the rough surface of observing drive pipe, this process probably needed for 30 seconds;
5) at first drive pipe surface mucous fragment is done the liquid base and cultivated (cutting rough surface places in the culture fluid) or cell smear (being applied on the microscope slide roughened surface for adhesion cell fixing), the tissue fluid in the drive pipe is pushed in the uterine cavity cell-preservation liquid makes tissue specimen then;
6) carry out cytology and histopathologic diagnosis respectively.
The beneficial effect that this utility model had is: an Endometrium sampler is provided, except can extracting intrauterine liquid tissue, can also extract endometrial mucosa cell by the rough surface of drive pipe front end, simple to operation, make patient's no pain, satisfied the noninvasive demand in present endometrium sampling field; With the head design of drive pipe is smooth hemispherical, also can alleviate patient's misery to a greater extent.
Description of drawings
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is the vertical view of drive pipe among Fig. 1;
Fig. 3 is two of a structural representation of the present utility model.
Among the figure: 1, smooth hemispherical tip; 2, sample tap; 3, rough surface; 4, drive pipe; 5, limited impression; 6, core bar; 7, hands handle; 8, piston
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Shown in Fig. 1~3, the endometrium sampler comprises drive pipe 4, core bar 6, piston 8 and handle 7, core bar 6 two ends are connected with handle 7 with piston 8 respectively, piston 8 is assemblied in the drive pipe 4 jointly with core bar 6, the head of drive pipe 4 has sample tap 2, afterbody is provided with limited impression 5, and the front end of drive pipe 4 is provided with rough surface 3, and the head of drive pipe 4 is smooth hemispherical tip 1.
Can gather liquid tissue in the uterus by drive pipe 4, and because drive pipe 4 front ends have the rough surface 3 of a segment distance, this rough surface 3 can extract easily to endometrial mucosa cell, simple to operate, make patient's no pain, satisfied the noninvasive demand in present endometrium sampling field, in addition, with the head design of drive pipe 4 is smooth hemispherical, also can alleviate patient's misery to a greater extent.Usually all be provided with scale marker on the drive pipe 4, be convenient to judge that the endometrium sampler enters the degree of depth in uterus.
Operation principle and process:
Before the use, first head with the endometrium sampler curves and meets the anatomical shape in uterus, then the endometrium sampler is inserted gently the bottom of uterus (having carried out thorough disinfection) by cervix uteri, and the degree of depth that judgement enters the uterus according to the scale marker on the drive pipe 4, aspirate core bar 6 afterwards, with form negative pressure with liquid tissue from sample tap 2 suction drive pipes 4, in operating process, thereby the endometrium sampler can be moved forward and backward with left rotation and right rotation and extract endometrial mucosa cell, to obtain more comprehensively sampling, after sampling finishes, take out sampler, the front end (comprising rough surface 3) of sampler is cut and the mucosa cell making cell smear or the liquid base that adhere on the rough surface 3 are cultivated, with core bar 6 liquid tissue is pushed in the uterine cavity cell-preservation liquid at last and make tissue samples.
Whole endometrium sampler is except can extracting intrauterine liquid tissue, can also extract endometrial mucosa cell by the rough surface 3 of drive pipe 4 front end settings, simple to operation, make patient's no pain, satisfied the noninvasive demand in present endometrium sampling field; In addition, be smooth hemispherical with the head design of drive pipe 4, also can alleviate patient's misery to a greater extent.
