Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a cervical biopsy sampler.
Background
With the popularization of cervical cancer screening, the diagnosis rate of cervical cancer and precancerous lesions is gradually increased. According to current practice, the definitive diagnosis of cervical cancer and precancerous lesions depends on the pathological examination of cervical biopsy.
The anatomical structure of human cervical tissue is similar to a hollow cylinder, the upper end of the cervical tissue is connected with a uterus and is positioned in a pelvic cavity, the lower end of the cervical tissue is exposed in a vagina, and the cervical tissue can be observed after the vagina is dilated. The surface of the cervix exposed to the vagina is not planar and has great individual variation, and the cervix of women of different ages has different hardness and histological structure, and most of young women have soft texture, while the cervix of menopausal women has tough texture.
Pathological examination of cervical tissue requires that tissue samples be taken to a certain width (greater than 3 mm) and depth, and that the tissue be taken with integrity to facilitate the visualization and diagnosis of the tissue sections. Lesions of the cervix may occur in any area of the cervix, either on the surface of the cervix, within the cervix, or on a slope at the junction of the surface of the cervix and the cervix.
Due to individual differences of human cervix uteri and diversity of cervical lesion positions, a cervical biopsy sampler is urgently needed, biopsy sampling can be performed on tissues of different textures of cervix uteri/different regional positions, positioning is required to be accurate, sampling is convenient, cross contamination is avoided, the purpose of improving diagnosis accuracy of cervical diseases is achieved, and the cervical biopsy sampler is suitable for being widely applied to hospitals at all levels.
At present, most of common cervical biopsy devices in hospitals and on the market are clamp type cervical biopsy forceps.
The clamp type cervical biopsy forceps are difficult to fix and easy to slip when used for treating cervical slope tissues, particularly when used for cervical texture biopsy of menopausal women, satisfactory tissues are difficult to obtain, even the tissues are clamped for multiple times, so that the tissues are damaged, histopathology examination is not facilitated, and pain of patients is increased;
The pincers clamp formula cervical biopsy pincers use time clamp dynamics and cervical texture relevant, and the dynamics is difficult for mastering, and too big patient of dynamics is painful to be increased, and the dynamics undersize pincers get the tissue inadequately, and the operation degree of difficulty is high, is difficult to use in extensive inspection.
The forceps clip type cervical biopsy forceps have the advantages that the section can not be replaced, the whole cervical biopsy forceps need to be updated after being sterilized for use for several times, and the cost is high; and the repeated use has cross contamination risk.
In summary, the conventional cervical biopsy forceps exist: inaccurate positioning, difficult clamping, high operation difficulty, high cost and potential cross contamination risk.

The top end of the disposable sampling head (3) is provided with a positioning needle made of stainless steel or other materials, and the needle can be directly inserted into a selected tissue for positioning.
The conical surface of the disposable sampling head (3) is provided with a stainless steel blade for rotary cutting sampling.
The tail end of the disposable sampling head (3) is connected with the sleeve (4) in a buckling mode, and the inner hexagon and the sampling rod (5) are limited in rotation.
The sampling rod (5) can be made of stainless steel or high polymer materials, has light weight and high strength, and can resist high-pressure sterilization.
The handle (7) is made of high polymer materials, and the size and the shape of the handle accord with the mechanical grasping of a human body.
The sampling knob (9) is arranged at the tail end of the handle (7), and after the handle (7) is grasped by a single hand, the sampling knob (9) can be conveniently rotated by a thumb to sample.
The sampling button (9) and the sampling rod (5) are linked into a whole and are kept positioned by a spring (6) and a gasket (8) in the handle. The sampling head (3) can be disengaged by pressing the sampling button (9).
The utility model has the advantages that:
The sampling head (3) is made of high polymer materials, and is pre-sterilized after being packaged in a whole box according to daily workload, so that the sampling head is disposable, cross contamination is avoided, and the burden of cleaning and disinfection is reduced.
The tissue is inserted into the top positioning needle (1) through the sampling head (3) for positioning, so that the tissue positioning device is not influenced by factors such as tissue surface texture, lesion degree and visual field interference, and is accurate in positioning.
The conical surface of the disposable sampling head (3) is provided with a stainless steel rotary cutting blade (2), and after positioning, the sampling knob (9) at the tail end of the handle (7) is slightly rotated to realize rotary cutting sampling, so that the operation is simple and convenient.
The sampler is withdrawn after sampling, the sampling button (9) is pressed, the sampling head (1) is separated from the sleeve (4), and the sampling head can be transferred into the sample tube. And then the sleeve (4) is inserted into the next sampling head (3) for fixing, so that the next sampling is prepared, and the operation is convenient.
The disposable sampling head (3) is disposable, so that cross contamination can be effectively avoided, and the cleaning and disinfecting workload of hospitals is reduced.
