In order to clearly illustrate the technical features of the present solution, the present invention is explained in detail through the following embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1

As shown in figures 1-3, the TCT brush body device for uterine cavity examination comprises a brush cylinder 1 and a brush body movably arranged in the brush cylinder, wherein the brush cylinder is a transparent or semitransparent cylinder, and scales are arranged on the outer side of the brush cylinder; the bottom end of the brush cylinder is fixedly connected with a retaining ring 2 through a connecting rod, the connecting rod is a plurality of vertical connecting rods 3 which are uniformly arranged along the circumferential direction of the brush cylinder at intervals, and the vertical connecting rods play a role in supporting the retaining ring and the brush cylinder; the retainer ring is fixedly connected with the bottom end of the vertical connecting rod; the brush head 4 is arranged at the top of the brush body and is a fusiform brush head, the fusiform brush head consists of an upper scraping brush 4.1 and a bottom fixed seat 4.2, and the scraping brush is made of the same material as the traditional cervical TCT brush; a silica gel buffer part 5 is fixedly connected below the brush head, the bottom end of the silica gel buffer part is fixedly connected with the top end of the brush rod 6, and the silica gel buffer part is a connecting column with the outer diameter slightly larger than that of the brush rod; a column body 7 which is in sliding fit with the inner side wall of the brush cylinder is fixedly sleeved at the bottom of the brush rod in the brush cylinder; the bottom end of the brush rod penetrates through the brush cylinder, a square bottom support 8 is fixedly connected to the bottom end of the brush rod, and the front side and the rear side of the square bottom support protrude out of the outer edge of the bottom support; the brush rod is in friction sliding fit with the inner side wall of the brush cylinder through the cylinder 7 under the push-pull action of the square bottom support 8, and drives the brush head to enter and exit the brush cylinder. The length of the brush head is 3cm, the outer diameter of the brush barrel is 5mm, the length of the brush barrel is 16cm, and the whole length of the brush head is about 20cm after the brush head is completely exposed out of the brush barrel, so that the brush head can smoothly enter a uterine cavity and contact the wall of the uterine cavity, and the brush head can be prevented from being directly pushed to the rear wall of the uterine cavity of a patient to cause damage.

When in use, the device is used for collecting uterine cells of a patient for follow-up TCT examination of the uterine cells. Expand earlier and see doctor's vagina and cervical orifice, the handheld brush section of thick bamboo of inspection doctor, forefinger and middle finger support at retaining ring 2 and vertical connecting rod 3 junction, the thumb dabs in square collet 8 position, stretch into doctor's vagina and cervical orifice with the device level, then stretch into the palace intracavity, the inspection doctor can be according to the scale on the brush section of thick bamboo, the grasp stretches into position and distance, treat that brush section of thick bamboo front portion stretches into the palace chamber, the thumb promotes square collet 8, the collet promotes the rear end of brush-holder stud 6, cylinder 7 on the brush-holder stud under the thrust effect with brush section of thick bamboo inside wall sliding fit, drive the brush head and stretch out brush section of thick bamboo foremost gradually. Through earlier stage design, when guaranteeing that square collet 8 supports together with retaining ring 2, brush head 4 and silica gel buffering portion 5 stretch out a brush section of thick bamboo outside completely to this makes things convenient for brush head work. The inspection doctor holds brush section of thick bamboo rearmost end behind collet and retaining ring butt, makes the action of brush section of thick bamboo upper and lower, left and right, and at this moment, the brush head can contact each lateral wall in palace chamber, through the action of control brush section of thick bamboo, makes the brush head realize the brushing of palace intracavity wall cell or be stained with and get with the in-process of palace chamber wall contact. Because the silica gel buffer part is arranged, the force of brushing the inner wall of the uterine cavity when the brush head is stained with cells is buffered by virtue of certain flexible force of the silica gel buffer part, and the discomfort of a patient is relieved. After collection, the examining doctor can withdraw the brush head for brushing the uterine cavity cells into the brush cylinder again by pulling back the square bottom support 8, and then gradually move out of the brush cylinder. Uterine cavity cells collected by the brush head are used for TCT examination subsequently, and the illness state of the patient is pre-judged pharmacologically according to the cytological auxiliary examination result.

Example 2

As shown in fig. 4 to 5, the difference between the TCT brush body device for uterine cavity examination and the TCT brush body device for uterine cavity examination of example 1 is that the vertical state of the brush head is changed to be inclined, so that the brush head can be in contact with the inner wall of the uterine cavity more easily after being released, the pushing distance of the brush rod can be reduced during use, the extension length of the brush head can be reduced, the TCT brush body device is more beneficial to a doctor in front of the uterus, and the brush head is prevented from directly abutting against the rear wall of the uterus to cause injury

. The specific distinguishing structure is as follows: the top of the brush cylinder 1 is a bent cylinder head which is bent towards one side, and the brush head is an inclined brush head 9 which is in the same bending direction with the bent cylinder head; the inclined brush head 9 consists of an upper shuttle-shaped scraping brush and a bottom triangular seat 10, the bottom triangular seat is used for fixing the shuttle-shaped scraping brush, and the shape of the inverted triangular seat can prevent the brush head 4 from touching the brush cylinder 1 when entering and exiting the brush cylinder; the bending degree of the bent tube head is 20 degrees, the outer diameter of the brush tube with the inclined angle of the inclined brush head of 35 degrees is 6mm, the length of the brush tube is 17cm, and the length of the brush head is 3 cm.

The brush head of the TCT brush body device for uterine cavity examination is inclined, a silica gel buffer part is not needed to be additionally arranged between the brush head and the brush rod, the length of the brush barrel extending out is relatively shortened when the TCT brush body device is used, when an examining doctor swings the brush barrel, the brush head is more easily contacted with the inner wall of the uterine cavity, and the cell brushing effect is more labor-saving. Meanwhile, the whole extension length of the brush head is shortened, so that the damage of the brush head to the back wall of the uterine cavity can be further avoided when a patient before the uterus is examined on the premise of ensuring the extension into the uterine cavity.

The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.

The parts of the present invention not described in detail are the known techniques of those skilled in the art.
