Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a cervical specimen collector. Background Art

[0002] Currently, when collecting specimens from the cervix, a vaginodilator must be used to first dilate the vagina and expose the cervix. Then a scraper is inserted into the cervical canal and rotated so that the scraper at the front end of the scraper comes into contact with the wall of the cervical canal during rotation, and the specimen is retained on the scraper to complete the specimen collection process.

[0003] However, the scraper at the front end of the scraper currently used in clinical practice has a ring-shaped structure and a hollow setting in the middle, that is, there is no shielding structure in the area behind the scraper. When collecting specimens, the area on the scraper with the ring-shaped structure that can retain the specimen is relatively small. At the same time, after the scraper with the ring-shaped structure has collected the specimen and is pulled out from the cervical canal, the specimen is easy to fall off the scraper with the ring-shaped structure, resulting in insufficient specimen collection. Therefore, it is necessary to insert the scraper into the cervical canal for multiple times to obtain a sufficient amount of specimen, which brings inconvenience to the collection operation of medical staff. Utility Model Content

[0034] When in use, medical personnel can hold the handle part 2 to control the front collection part 1. When it is necessary to collect a specimen from the cervical canal, they can first use a vaginal dilator to expand the vagina and expose the cervical canal, then manipulate the handle part 2 to adjust the indicator mark 3 to face downward, then extend the collection part 1 through the vagina to the cervical canal, then move the handle part 2 slightly downward so that the groove 11 area on the collection part 1 can fit on the inner wall of the cervical canal, then observe the indicator mark 3 to control the handle part 2 to perform the downward pressure action. At the same time, the indicator mark 3 on the handle part 2 will face upwards, and the collecting part 1 will perform a similar digging action in the cervical canal, so that the specimen on the inner wall of the cervical canal can be retained in the groove 11 area of ​​the collecting part 1. Then the handle part 2 can be pulled backwards. During the operation, the indicator mark 3 must be kept facing upwards. After the handle part 2 separates the collecting part 1 from the cervical and vaginal parts, the collecting part 1 with the specimen retained can be placed in the specimen storage container to complete the collection operation of the cervical specimen.

[0036] In a further preferred embodiment, refer to the attached Figures 7 to 9 As shown, a limiting groove 22 is provided inside the clamping block 21 near its upper end, and a stopper 23 is provided inside the limiting groove 22. A clamping shaft 24 is vertically provided above the stopper 23. The bottom end of the clamping shaft 24 is fixedly connected to the upper surface of the stopper 23, and the top end of the clamping shaft 24 passes through the limiting groove 22 and extends to the outer area of ​​the clamping block 21. The stopper 23 can drive the clamping shaft 24 to move up and down, so that the upper half of the clamping shaft 24 can be transferred in the limiting groove 22 of the clamping block 21 and the outer area of ​​the limiting groove 22. A positioning hole 13 that matches the size of the upper half of the clamping shaft 24 is provided on the inner wall of one side of the clamping groove 12 at the end of the collecting component 1.

[0037] See attached Figures 7 to 9 As shown in the figure, the lower part of the stopper 23 facing the end of the handle part 2 is arranged as an inclined surface, that is, the stopper 23 is arranged in an inverted semi-trapezoidal shape, referring to the attached Figures 7 to 10 As shown, a cylindrical slide groove 25 is provided inside the handle component 2, and the slide groove 25 extends from the end of the handle component 2 to the limiting groove 22 area in the clamping block 21. A support rod 26 is provided in the slide groove 25 of the handle component 2, and the support rod 26 can rotate and translate in the slide groove 25;

[0038] See attached Figures 5 to 10 As shown, an adjusting member 27 is provided at the end of the support rod 26, that is, the adjusting member 27 is located at one end of the support rod 26 away from the clamping block 21, and the adjusting member 27 is fixedly connected to the end of the support rod 26, and the adjusting member 27 is cylindrically arranged, and a cylindrical groove 271 is arranged at the end of the handle component 2 to accommodate the adjusting member 27 for rotation and translation. The end portion of the adjusting member 27 passes through the cylindrical groove 271 and extends to the outer area of ​​the end of the handle component 2, and a thread 28 is arranged on the outside of the adjusting member 27, and a thread groove matching the thread 28 on the adjusting member 27 is arranged on the inner wall of the cylindrical groove 271 on the handle component 2;

[0039] When installing the collection component 1 and the handle component 2, the clamping block 21 at the top of the handle component 2 can be inserted into the clamping groove 12 at the end of the handle component 2, and the adjustment member 27 exposed at the end of the handle component 2 can be controlled, and the adjustment member 27 can be gradually screwed in toward the front end of the handle component 2, so that the thread 28 on the adjustment member 27 and the thread groove in the cylindrical groove 271 are threadedly matched, and the entire support rod 26 is driven to translate in a rotational state toward the front end of the handle component 2. As the front end of the support rod 26 extends into the limiting groove 22 of the clamping block 21, the front end of the support rod 26 will first contact with the stop block The inclined surface of the stop block 23 is in contact with the support rod 26, and as the support rod 26 continues to push the inclined surface of the stop block 23 until it contacts the bottom of the stop block 23, the stop block 23 will be pushed upward, so that the stop block 23 pushes the clamping shaft 24 out of the limiting groove 22 and inserts it into the positioning hole 13 at the clamping groove 12 at the end of the collection component 1. The clamping shaft 24 implements a limiting effect between the clamping block 21 and the clamping groove 12, which can prevent the clamping block 21 from detaching from the clamping groove 12, thereby realizing the locking function after the collection component 1 and the handle component 2 are installed, thereby completing the installation operation of the collection component 1.

[0040] In a further preferred embodiment, refer to the attached Figures 7 to 9 As shown, a spring 29 is sleeved on the clamping shaft 24, and the spring 29 is located between the top of the stop block 23 and the top area of ​​the limit groove 22 in the clamping block 21.

Under the thrust of the two ends of the spring 29, a pushing action can be applied to the stop block 23 and the limit groove 22 above the stop block 23.

[0041] When the specimen collection is completed, the medical staff can use one hand to control the handle component 2 and place the collection component 1 into the specimen storage container, and then use the other hand to rotate the adjustment member 27 so that the adjustment member 27 is rotated out toward the end of the handle component 2, thereby driving the support rod 26 to translate in a rotating state toward the end of the handle component 2. As the front end of the support rod 26 gradually disengages from the limiting groove 22 of the clamping block 21, the pushing action on the stop block 23 will stop. At this time, under the action of the expansion force of the spring 29, the spring 29 will push the stop block 23 downward, and the stop block 23 will be pushed downward. The front half of the clamping shaft 24 is driven to gradually disengage from the positioning hole 13 of the clamping groove 12 at the end of the collection component 1 and retract into the limiting groove 22. At this time, the clamping block 21 and the clamping groove 12 return to the active state, and the locking function between the collection component 1 and the handle component 2 also stops. At this time, the medical staff can shake the handle component 2 slightly to make the collection component 1 fall from the handle component 2 into the specimen storage container. During the operation, the medical staff does not need to touch the collection component 1 to remove it, which can bring convenience to the operation of the medical staff.

[0042] In a further preferred embodiment, it also includes a brush component 4, which is a cervical sampling brush. The end structure of the brush component 4 is the same as the end structure of the collecting component 1. After using the collecting component 1 to complete the specimen collection of the cervix, the collecting component 1 can be replaced with the brush component 4 to continue to collect specimens from the cervix again, thereby increasing the amount of specimen collection to facilitate subsequent diversified inspections.
