Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a cervical sampler. Background Technology

[0002] A cervical sampler is a medical device specifically designed for sampling and examining the cervical endometrial tissue of women. It is mainly used for the screening, diagnosis, and treatment of cervical cancer and cervical lesions. The sampler typically consists of a tube and a flexible membrane, and its shape resembles a small pen, but it is longer and has a slightly curved end.

[0003] The "Cervical Cell Sampler" disclosed in application number "03221231.3" consists of a brush handle and bristles. The bristles are located on the brush handle, and the number of bristles in the central region and on both edges is greater than the number of bristles in the region between the central region and the edges. This invention uses an uneven arrangement of bristles, with a large number in the central and edge regions and a smaller number in the region between the central region and the edges. This allows the sampler to be inserted into the cervical canal more smoothly and to increase the insertion depth when collecting cells. The reduction in the number of bristles between the central region and the edges can reduce and alleviate the patient's pain. Therefore, this invention can reduce the examination pain for women being examined.

[0004] However, the above method still has the following drawbacks: because the brush head is a flat, soft, plate-shaped brush head with a high middle and low ends, it can be used to brush the squamocolumnar junction cells of the cervix with the assistance of a cervical dilator. This type of sampler is suitable for most female patients, but it cannot be used to sample the cervix of patients with cervical atrophy or after conization, resulting in sampling failure. Utility Model Content

[0005] The technical problem to be solved by this invention is to provide a cervical sampler that can sample the cervix of patients with cervical atrophy or after conization, and can brush up cells in the squamocolumnar junction area.

[0006] This utility model provides a cervical sampler, including a support rod; a spike is fixedly provided at the top of the support rod, a soft brush is fixedly provided on the surface of the spike, and a sleeve is fitted on the surface of the spike. Both the sleeve and the spike are made of silicone. A ball head is fixedly provided at the top of the sleeve, and an opening is provided in the middle of the top of the ball head. A support plate is fixedly provided at the bottom of the sleeve, and a rod sleeve that is slidably connected to the support rod is fixedly provided in the middle of the support plate. A push-pull plate is fixedly provided at the bottom of the rod sleeve, and a sleeve is installed on one side of the bottom of the push-pull plate. A support component is provided at the top of the sleeve, and a positioning component is provided inside the sleeve.

[0007] By adopting the above-described structure, this invention guides the cannula via the ball head, allowing it to be inserted into the cervix. When sampling the cervix of patients with cervical atrophy or after conization, the cannula reaches the sampling site. Because the spiked rod is located inside the cannula, its cleanliness is maintained during insertion, preventing the soft brush from becoming saturated and ensuring its ability to collect cells. By pulling back the cannula, it can be removed from the spiked rod through the opening, exposing it. The spiked rod, with its soft brush, can collect cells from the squamocolumnar junction, ensuring accurate sampling. This facilitates deep sampling into the narrow cervical canal, such as in cases of atrophy or conization. The support component facilitates the installation of the cannula and provides support. The positioning component prevents movement between the rod and support rod during cannula insertion, ensuring stability and reliability. Releasing the cannula via the positioning component prevents the support rod from being carried out during pullback.

[0008] In one possible implementation, the support assembly includes a support, the bottom of which is fixedly connected to the top of the sleeve, and a locking block for installing the sleeve is fixedly provided at the top of the support. A deformation groove is provided in the middle of the top of the locking block, and protrusions are fixedly provided on both sides of the top of the locking block. The sleeve can be installed and removed through the locking block and the support. During the installation and removal of the sleeve, the deformation groove of the locking block can undergo elastic deformation under force.

[0009] In one possible implementation, a slot is provided on one side of the bottom end of the push-pull plate, and the locking block engages with the inside of the slot; the slot can limit the locking block and prevent it from loosening and falling off, and the locking block can provide stable support for the sleeve through the support.

[0010] In one possible implementation, a protrusion is fixedly provided on the surface of the support rod, and a groove is provided on the inner wall of the rod sleeve. The protrusion and the groove are slidably connected. The protrusion and the groove can prevent rotation between the support rod and the rod sleeve, thereby ensuring the positional accuracy of the positioning component.

[0011] In one possible implementation, the bottom end of the support rod is fixedly provided with threads, and a nut is connected to the bottom end of the support rod through the threads. The surface of the nut is provided with anti-slip grooves, and a retaining ring is fixedly provided on the top of the nut. The nut can be installed through the threads, the nut can prevent the rod sleeve from falling off, and the anti-slip grooves facilitate the rotation of the nut.

[0012] In one possible implementation, the positioning component includes a slider that is slidably connected to the inside of the sleeve. A limiting rod is fixedly provided in the middle of the slider. The bottom of the support rod has a limiting groove 1 and a limiting groove 2 corresponding to the position of the limiting rod. A spring is sleeved on the surface of the limiting rod, and a finger groove is provided on one side of the limiting rod. The limiting rod can limit the spring, and the spring can push the limiting rod into the inside of the limiting groove 1 through the slider, thereby preventing slippage between the support rod and the sleeve. During the sampling process, the stability of the sleeve and the spiked club can be maintained. By pulling the limiting rod through the finger groove, the slider compresses the spring, which can pull back the sleeve, and the limiting rod can be positioned through the limiting groove 2.

[0013] In one possible implementation, a threaded cap is threaded to one end of the sleeve. The middle of the threaded cap and the middle of the other end of the sleeve are both provided with rod grooves that slide in connection with the limiting rod. The threaded cap can limit the spring and prevent it from falling out of the sleeve. The rod grooves of the threaded cap and the sleeve can guide the limiting rod and ensure the linear movement of the limiting rod.

[0014] In one possible implementation, a ball head is fixedly provided at the bottom end of the support plate, and the middle part of the ball head is fixedly connected to the top of the sleeve. The ball head can guide the sleeve during the pull-back process, thereby reducing the pull-back resistance of the sleeve. Attached Figure Description

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] See Figure 1-6As shown in the embodiment of this application, a cervical sampler is disclosed, including a support rod 1; a spike 2 is fixedly provided at the top of the support rod 1, a soft brush 3 is fixedly provided on the surface of the spike 2, and a sleeve 4 is fitted on the surface of the spike 2. Both the sleeve 4 and the spike 2 are made of silicone material. A ball head 5 is fixedly provided at the top of the sleeve 4, and an opening 6 is provided in the middle of the top of the ball head 5. A support plate 7 is fixedly provided at the bottom of the sleeve 4, and a rod sleeve 9 that is slidably connected to the support rod 1 is fixedly provided in the middle of the support plate 7. A push-pull plate 14 is fixedly provided at the bottom of the rod sleeve 9, and a sleeve 15 is installed on one side of the bottom of the push-pull plate 14. A support component 16 is provided at the top of the sleeve 15 to support it, and a positioning component 17 is provided inside the sleeve 15 to position the rod sleeve 9. First, the rod sleeve 9 is fixed to the support rod 1 by the positioning component 17. Then, the cannula 4 is inserted into the cervix through the support rod 1. The ball head 5 can guide the cannula 4. When sampling the cervix of patients with cervical atrophy or after conization, the cannula 4 can reach the sampling site. Since the spike 2 is located inside the cannula 4, it can keep the spike 2 clean during the insertion process and prevent the soft brush 3 from becoming saturated. Then, the rod sleeve 9 is released through the positioning component 17, and the cannula 4 is pulled back. The cannula 4 can be removed from the spike 2 through the opening 6, thus exposing the spike 2. This ensures the soft brush 3's ability to collect cells. The spike 2 can brush cells in the squamocolumnar junction area through the soft brush 3, ensuring the accuracy of the sampling position. This facilitates sampling into the narrow cervical canal, such as in cases of atrophy or conization. After the spike 2 collects cells through the soft brush 3, it can be removed.

[0028] See you again Figure 4-5 As shown, the support assembly 16 includes a support 1601. The bottom of the support 1601 is fixedly connected to the top of the sleeve 15. A locking block 1602 for installing the sleeve 15 is fixedly provided at the top of the support 1601. A deformation groove 1603 is provided in the middle of the top of the locking block 1602. Protrusions 1604 are fixedly provided on both sides of the top of the locking block 1602. A slot 18 is provided on one side of the bottom of the push-pull plate 14. The locking block 1602 is engaged with the inside of the slot 18. By pressing the locking block 1602 into the slot 18, the locking block 1602 can deform through the deformation groove 1603, and the protrusions 1604 can be pushed into the slot 18, thus installing the locking block 1602. The locking block 1602 can support the sleeve 15 through the support 1601, which facilitates the installation of the sleeve 15.

[0029] See you again Figure 4-6As shown, the positioning assembly 17 includes a slider 1701, which is slidably connected to the inside of the sleeve 15. A limiting rod 1702 is fixedly provided in the middle of the slider 1701. The bottom of the support rod 1 has a limiting groove 12 and a limiting groove 13 corresponding to the position of the limiting rod 1702. A spring 1703 is sleeved on the surface of the limiting rod 1702. A finger groove 1704 is provided on one side of the limiting rod 1702. A threaded cap 21 is threaded to one end of the sleeve 15. The middle of the threaded cap 21 and the middle of the other end of the sleeve 15 are both provided with grooves corresponding to the position of the limiting rod 1702. 2. The sliding groove 22 of the rod is connected; the spring 1703 can support the slider 1701, and one end of the limiting rod 1702 can be pushed into the inside of the limiting groove 12 to prevent the sleeve 9 from sliding on the support rod 1. By pulling the limiting rod 1702 through the finger groove 1704, the slider 1701 can compress the spring 1703, and the limiting rod 1702 can retract, thereby sliding the sleeve 9. The sleeve 9 can be pulled back, and after the sleeve 9 is pulled back, the limiting rod 1702 is pushed into the inside of the limiting groove 13. During the sampling process, the stability of the spiked rod 2 and the sleeve 4 can be maintained.

[0030] See you again Figure 1-3 As shown, a protrusion 10 is fixedly provided on the surface of the support rod 1, and a groove is provided on the inner wall of the sleeve 9. The protrusion 10 is slidably connected to the inside of the groove. During the sliding of the sleeve 9, the protrusion 10 and the groove can prevent the sleeve 9 from rotating with the support rod 1, so that the limiting rod 1702, the limiting groove 12 and the limiting groove 13 are located on the same vertical plane, and its positional accuracy can be maintained. A thread 11 is fixedly provided at the bottom end of the support rod 1, and a nut 19 is threadedly connected to the bottom end of the support rod 1 through the thread 11. An anti-slip groove is provided on the surface of the nut 19, and a retaining ring 20 is fixedly provided at the top of the nut 19. By tightening the nut 19, the nut 19 can prevent the push-pull plate 14 from slipping off through the retaining ring 20.

[0031] See you again Figure 1 As shown, a ball head 8 is fixedly provided at the bottom end of the support plate 7. The middle part of the ball head 8 is fixedly connected to the top of the sleeve 9. During the process of pulling back the sleeve 4, the ball head 8 can guide the sleeve 4 and the support plate 7, reducing the pullback resistance of the sleeve 4 and the support plate 7.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
