Description
Technical field
The utility model is related to field of medical appliances, and in particular to a kind of dual collection sampling brush.
Background technology
At present, in the detection clinical practice of women cervical carcinogenesis is carried out, cervix is entered using scraping blade method first more than doctor
Row cell sample, extracts cervical exfoliated cell, and then cervical exfoliated cell is put in preservation liquid, 24 hours are stood, then will dress
The preservation liquid for having cervical exfoliated cell pours into centrifuge tube, and centrifuge tube is arranged on centrifuge, uterine neck is come off carefully by centrifuge
Born of the same parents separate with preserving liquid.
Traditional gynaecology's diagnosis and treatment are mainly using erasion is examined, i.e., for the physiological sample for extracting endometrial tissue, first to palace
Neck is expanded scrapes uterine cavity to facilitate curet turnover uterine cavity to scratch, and the brush of existing sampling brush is excessive, and foreign body sensation is had when being put into,
Certain pain is caused to operation receiveing person, existing bristle lengths are all fixed, but the ostium of uterus of each patient is all not
With, it is difficult to which perfect cooperation, there is a situation where once not collect.
The Uterine neck bush and opening of the cervix sampling brush often used at present is two separated stand-alone products, to be separated when both use
Use, need to be used alone when using, error-prone during such doctor's operation, while adding the time of censored sample, is given
Patient brings pain.
Utility model content
For deficiency of the prior art, the utility model provides a kind of dual collection sampling brush, to solve existing take
The brush of sample brush is excessive, and foreign body sensation is had when being put into, and causes patient's pain, and the bristle lengths coordinated with ostium of uterus can not
Adjust, the problem of sampling failure can be caused.
To achieve the above objectives, the technical solution adopted in the utility model is：
Dismountable brush is disposed with from top to bottom in a kind of dual collection sampling brush, including brush holder support, described brush holder support
Head, bristle, sliding block and reverse-flighted screw, the bottom of described bristle are fixed on sliding block, and described slide block set is located at reverse-flighted screw
It is upper and can be slided up and down with the rotation of reverse-flighted screw, it is provided with motor below described reverse-flighted screw, the lower section of described motor
It is connected with handle, described brush holder support and is provided with A-frame, the center of described A-frame is provided with internal thread
Mounting seat, described brush bottom is provided with externally threaded cylinder, and cylinder is used for the cooperation with mounting seat.Using dual
The mode of collection, reduces the workload of doctor, and can control the length of bristle manually, is adapted to different sufferers, observes
The pain degree of sufferer, ensures the success rate of collection, and the foreign body sensation of human body is reduced when stretching into brush holder support.
Preferably, be provided with switch on described handle, the unlatching of described switch controlled motor.Control stretching for bristle
Go out is to rely on the switch in outer handle, it is ensured that cleannes, doctor uses more smoothly.
Preferably, the angle between any two legs of described A-frame is 120 degree.Good stability, intensity
Height, bristle can be passed between angle.
Compared with prior art, the utility model has the advantages that：The device can mitigate operation to patient with
The pain come, adjusts bristle lengths manually, ensures the endo cell tissue collected comprehensively in patient uterine, and bristle is not when being put into
Stretch out, significantly reduce foreign body sensation when entering internal.

Embodiment
Describe to be used to disclose the utility model so that those skilled in the art can realize the utility model below.Retouch below
Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modifications.
It is disposed with from top to bottom in a kind of dual collection sampling brush, including brush holder support 5, described brush holder support 5 dismountable
Brush 7, bristle 6, sliding block 4 and reverse-flighted screw 3, the bottom of described bristle 6 are fixed on sliding block 4, and described sliding block 4 is sheathed on
It can be slided up and down on reverse-flighted screw 3 and with the rotation of reverse-flighted screw 3, the described lower section of reverse-flighted screw 3 is provided with motor 2, described
The lower section of motor 2 be connected with handle 1, described brush holder support 5 and be provided with A-frame 71, the center of described A-frame 71
The heart is provided with female mounting seat 72, and the described bottom of brush 7 is provided with externally threaded cylinder, described cylinder
For the cooperation with mounting seat 72, switch is provided with described handle 1, the unlatching of described switch controlled motor 2 is described
Angle between any two legs of A-frame 71 is 120 degree.
When in use, brush 7 is first screwed into mounting seat 72, due to being the cooperation of external screw thread and internal thread, therefore brush 7
Extension elongation it is controllable, and can individually disassemble, change the brush of different size into, significantly brief cost.
