Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sampling device for cervical cancer. Background Art

[0002] At present, the examination and treatment of many uterine diseases require dilation of the uterine cervix. Clinically, multiple metal dilators of different diameters are often used, which are inserted into the cervical opening in sequence to gradually expand the cervical opening. This operation method is not only cumbersome, time-consuming and labor-intensive, but also causes great pain to patients. Sampling and testing operations are often performed when treating cervical diseases.

[0003] Traditional cervical cancer sampling requires medical staff to use a cotton swab to scrape the inside of the patient's cervix several times. Since the patient's cervix has a certain depth and the vagina is always in a closed state, the medical staff use the cotton swab to insert the sample, which leads to inaccurate sampling, thus affecting the treatment effect. Therefore, a cervical cancer sampling device is proposed. Utility Model Content

[0004] The utility model aims to solve the problems raised by the background technology and provides a sampling device for cervical cancer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sampling device for cervical cancer comprises a holding tube and two open covers, wherein one end of the holding tube is located inside the two open covers, and the other end of the holding tube is located outside the two open covers, a rotating rod is fixedly provided on the inner side walls of the two open covers, and one end of the two rotating rods away from the open covers is elastically rotatably connected to both sides of the holding tube; finger pressing rods are fixedly provided on both sides of the tops of the two open covers.

[0007] Preferably, rotation grooves are provided on both sides of the holding tube, and the end of the rotating rod away from the expansion cover is rotatably arranged inside the rotating groove through a rotating shaft. A torsion spring is sleeved on the shaft wall of the rotating shaft, and the two ends of the torsion spring are fixedly connected to the rotating groove and the rotating rod respectively.

[0008] Preferably, the two expanded covers form a truncated cone-shaped cover body, and the upper end size of the two expanded covers is larger than the lower end size.

[0009] Preferably, the lower ends of the two expansion covers adopt a closed structure.

[0010] Preferably, finger pressing rings are fixedly provided on the upper ends of the two finger pressing rods.

[0011] Preferably, the height of the finger pressing ring is smaller than the height of the holding tube.

[0012] Compared with the prior art, the utility model provides a cervical cancer sampling device, which has the following beneficial effects:

[0013] 1. The sampling device for cervical cancer is provided with a holding tube, a stretching cover, a rotating rod and a finger pressing rod. The medical staff first inserts the tips of the two stretching covers into the vagina. After the tips are fully inserted, the hands press the finger pressing rods on both sides to rotate the rotating rods on the two stretching covers and the holding tube, so that the vagina can be stretched. At this time, the sampling cotton swab can be inserted into the holding tube and directly reach the sampling position, which is convenient for direct sampling with high accuracy.

[0014] 2. The sampling device for cervical cancer is provided with a rotating shaft and a torsion spring. When the two spread covers are opened, one end of the rotating rod needs to rotate through the rotating shaft and generate a torsional pulling force on the torsion spring. When the hand releases the external force on the finger pressing rod, the torsion spring resets the two spread covers.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has a support structure, which is convenient for directly inserting the sampling cotton swab and performing accurate sampling, thereby improving the treatment effect on the patient.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Example 1

[0024] Reference Figure 1-2 4. A sampling device for cervical cancer, comprising a holding tube 1 and two open covers 2, the two open covers 2 forming a truncated cone-shaped cover body, the upper end size of the two open covers 2 being larger than the lower end size, the lower ends of the two open covers 2 adopting a closed structure, one end of the holding tube 1 being located inside the two open covers 2, and the other end of the holding tube 1 being located outside the two open covers 2, the inner side walls of the two open covers 2 are fixedly provided with a rotating rod 3, the ends of the two rotating rods 3 away from the open covers 2 are elastically rotatably connected to the two sides of the holding tube 1, the top sides of the two open covers 2 are fixedly provided with finger pressing rods 4, the two finger pressing rods 4 are fixedly provided to the two sides of the top of the two open covers 2, and the two finger pressing rods 4 are fixedly provided to the two sides of the top of the two open covers 2. A finger pressing ring 7 is fixedly provided at the upper end of the pressure rod 4. The height of the finger pressing ring 7 is less than the height of the holding tube 1. The finger pressing ring 7 is convenient for medical staff to hold and insert, thereby improving the pressing effect of the finger pressing rod 4 and avoiding slipping. The medical staff first inserts the tips of the two expansion covers 2 into the interior of the vagina. After the insertion is complete, the hand presses the finger pressing ring 7 on both sides to make the rotating rod 3 on the two expansion covers 2 rotate with the holding tube 1, so that the vagina can be expanded. At this time, the sampling cotton swab can be inserted into the interior of the holding tube 1 and directly reach the sampling position, which is convenient for direct sampling with high accuracy.

[0025] Example 2

[0026] Reference Figure 2-3 , rotation grooves are provided on both sides of the holding tube 1, and the end of the rotating rod 3 away from the spread cover 2 is rotatably arranged in the inside of the rotating groove through the rotating shaft 5, and the axial wall of the rotating shaft 5 is sleeved with a torsion spring 6, and the two ends of the torsion spring 6 are respectively fixedly connected to the rotation groove and the rotating rod 3, and one end of the rotating rod 3 can be rotatably connected to the holding tube 1 through the rotating shaft 5. When the two spread covers 2 are opened, one end of the rotating rod 3 needs to rotate through the rotating shaft 5 and generate a torsional tension on the torsion spring 6. When the hand releases the external force on the finger pressing rod 4, the torsion spring 6 resets the two spread covers 2.
