Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.

Referring to fig. 1-7, the cervical lesion detection sampler provided by the utility model comprises a sampling main body 1, wherein a vaginal dilation device 2 for dilating vagina is arranged on the periphery of the sampling main body 1, the sampling main body 1 comprises a rotating device 4, the rotating device 4 comprises a screw 41, the vaginal dilation device 2 comprises two lantern rings 21 which are sleeved on the periphery of the screw 41 and are in threaded connection with the screw 41, a plurality of expansion rods 22 are arranged on the periphery of the two lantern rings 21, a connecting rod 23 is rotationally connected between the expansion rods 22 and the lantern rings 21, a limiting device 5 for limiting the lantern rings 21 to synchronously rotate along with the screw 41 is arranged between the screw 41 and the vaginal dilation device 2, a cotton swab 3 is arranged at the end part of the screw 41, and the end part of the cotton swab 3 penetrates through the screw 41 and is in sliding connection with the screw 41.

Specifically, sample main part 1 inserts in the vagina, expand the vagina device 2 and expand the vagina to vaginal wall later, thereby leak more operable space, make cotton swab 3 contact to cervical department that can be more convenient, reduce the operation during self-sampling and be out of specification, the cotton swab 3 does not have the probability of accurate contact cervical department, rotating device 4 rotates, drive two lantern rings 21 and do relative motion, be close to each other or keep away from each other, when lantern rings 21 are close to each other or keep away from each other, through the support of connecting rod 23, drive connecting rod 23 and rotate, and then control extension rod 22 keep away from each other or be close to each other, thereby realize the extension to vaginal wall, stop device 5 is when rotating screw 41, carry out spacingly to lantern ring 21, avoid lantern ring 21 to rotate along with screw 41, lead to can't realize lantern ring 21 and remove, cotton swab 3 passes screw 41 and rather than sliding connection, make whole sample main part 1 can not produce the interference to cotton swab 3 when can not resampling, lead to the condition emergence of cotton swab 3 unable to put into the vagina, and sample main part 1 can protect cotton swab 3 when inserting, avoid cotton swab 3 too much to produce the contact with vaginal wall, lead to the cotton swab 3 to gluing on vaginal wall, and abundant sticky on vaginal wall, can't carry out the subsequent sampling.

The screw 41 is provided with a positive thread and a negative thread at both ends on the circumferential side thereof, and the two collars 21 are screwed with the positive thread and the negative thread, respectively.

Specifically, the screw 41 rotates, and drives the collars 21 to approach or separate from each other by the action of the positive thread and the negative thread, thereby realizing driving the expansion rod 22 to expand the vaginal wall.

The limiting device 5 comprises a second handheld portion 51 sleeved at two ends of the screw 41 and rotationally connected with the screw, a plurality of bosses 211 are fixedly connected to the periphery of the lantern ring 21, two ends of the connecting rod 23 are rotationally connected with the expansion rod 22 and the bosses 211 respectively, a plurality of limiting rods 52 are fixedly connected between the two second handheld portions 51, and each boss 211 is clamped between the two limiting rods 52 respectively.

Specifically, in use, the second handheld portion 51 is held by one hand, the second handheld portion 51 is fixed, and then the screw 41 is rotated, so that when the screw 41 rotates, the second handheld portion 51 does not rotate along with the rotation of the screw 41, the boss 211 is clamped by the limiting rod 52, and when the second handheld portion 51 does not rotate along with the rotation of the screw 41, the collar 21 is controlled to rotate along with the rotation of the screw 41 through the boss 211, so that the functions of the positive thread and the reverse thread can be realized, and the collar 21 is driven to perform corresponding displacement.

The inner wall of the second handheld portion 51 is fixedly connected with a T-shaped ring block 511, a T-shaped ring groove 421 matched with the T-shaped ring block 511 is formed in the circumferential side of the screw 41, and the end portion of the screw 41 is fixedly connected with a first handheld portion 42.

Specifically, the second handheld portion 51 is engaged with the T-ring block 511 and the T-ring groove 421, and is stably rotated on the screw 41, so that the second handheld portion 51 is not separated from the first handheld portion 42 and the second handheld portion 51 by one hand, and the screw 41 is rotated by manually rotating the first handheld portion 42, and the second handheld portion 51 is not rotated synchronously with the screw 41 by the other hand.

The end of the first hand-held portion 42 is provided with a cavity 411 penetrating the first hand-held portion 42 and the screw 41 in this order.

Specifically, the cotton swab 3 is inserted into the sampling main body 1 through the cavity 411 until the cotton swab is contacted with the cervical after extending out of the sampling main body 1 and is sampled, and is inserted into the vagina through the cavity 411, so that the contact with the vaginal wall in the process of inserting and taking out the cotton swab 3 can be reduced, the contact with the vaginal wall can be reduced as much as possible, and the condition that the sampling error or excessive mucus sticking to the vaginal wall influences the detection result can be reduced.

The outer side of the expansion rod 22 is fixedly connected with a flexible pad 221 in the shape of a circular arc.

Specifically, the flexible pad 221 is a plastic pad, so that the expansion rod 22 is prevented from directly contacting the vaginal wall, the flexible pad 221 is softer, discomfort caused by vaginal expansion during vaginal expansion can be reduced, and the vaginal wall is prevented from being damaged.

While certain exemplary embodiments of the present utility model have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the utility model, which is defined by the appended claims.
