Technical Field

[0001] The present invention relates to a sampling device for digestive endoscopy pathological specimens, belonging to the technical field of sampling devices. Background Art

[0002] Endoscopic pathological specimens are important bases for clinical digestive physicians to judge benign and malignant tumors and chronic inflammation of the gastrointestinal tract. The test results directly affect the diagnosis, treatment, and prognosis analysis of diseases. Rapid collection of pathological specimens during endoscopic examination can shorten the endoscopic examination time, reduce the pain of patients, and ensure the safety of patients.

[0003] Chinese Patent Publication (Publication No.: CN 217592926 U) discloses a sampling device for digestive endoscopy pathological specimens, including a base, a support rod, an orientation adjustment block, a back plate, and a clamping plate; the support rod is installed on the base; the first end of the orientation adjustment block is hinged to the end of the support rod away from the base; a connecting block is provided on the back plate, and the second end of the orientation adjustment block is hinged to the connecting block; a clamping surface is provided on the clamping plate, and the clamping plate can swing relative to the back plate so that the clamping surface of the clamping plate fits or disengages from the back plate; a plurality of clamping plates are provided; wherein, by designing a plurality of clamping plates on the back plate, multiple filter papers can be fixed simultaneously to avoid confusion caused by random placement of multiple filter papers; the design of the orientation adjustment block is used to adjust the swinging position of the back plate, improve its flexibility, and facilitate the user to pick up and place the filter paper; in addition, the above design has a compact overall structure and occupies less space;

[0033] Through the clamping mechanism 3, when the catheter 4 is punctured and placed, the catheter 4 is fixed to prevent the puncture from deviating and resulting in abnormal use. By providing the protection pad 5, the surface of the catheter 4 can be fixed when the catheter 4 is fixed, ensuring the normal use of the device.

[0034] Embodiment 2

[0035] As Figure 1 and Figure 3As shown, in one embodiment, a placement mechanism 6 is provided at the bottom of the syringe body 1. The placement mechanism 6 includes a placement plate 601, a contact block 602, and a pressing block 603. The bottom of the syringe body 1 is movably connected to the contact block 602. The bottom of the contact block 602 is fixedly connected to the placement plate 601. The bottom of the pressing block 603 is movably connected to the inside of the contact block 602. A plugging groove 7 is formed at the top of the contact block 602. The bottom of the pressing block 603 is movably connected to the inside of the plugging groove 7.

[0036] Through the placement mechanism 6, when the syringe body 1 is placed, the syringe body 1 is stably fixed, preventing the syringe body 1 from loosening, protecting the syringe body 1, and facilitating the medical staff to pick up and use the syringe body 1.

[0037] Embodiment 3

[0038] As Figures 4-6 shown, in one embodiment, a needle head 8 is movably connected to the left side of the syringe body 1. A positioning block 9 is fixedly connected to the left side of the syringe body 1. A cavity 10 is formed inside the positioning block 9. A fixing mechanism 11 is provided inside the cavity 10. The fixing mechanism 11 includes a moving rod 1101, a cross bar 1102, an inclined rod 1103, a positioning rod 1104, and a compression spring 1105. The top of the moving rod 1101 penetrates through the cavity 10 and extends to the top of the positioning block 9. The bottom of the moving rod 1101 penetrates to the inside of the cavity 10. The top of the cross bar 1102 is fixedly connected to the bottom of the moving rod 1101. The top of the inclined rod 1103 is movably connected to the front side of the cross bar 1102 through a rotating shaft. The top of the positioning rod 1104 is movably connected to the bottom of the inclined rod 1103 through a rotating shaft. The top of the compression spring 1105 is fixedly connected to the bottom of the cross bar 1102. The bottom of the compression spring 1105 is fixedly connected to the inside of the cavity 10. The inner side of the positioning rod 1104 penetrates through the needle head 8 and extends to the inside of the syringe body 1. A fixing groove 12 is formed on the surface of the syringe body 1. The inner side of the positioning rod 1104 is movably connected to the inside of the fixing groove 12. A limiting groove 13 is formed inside the cavity 10. A limiting rod 14 is fixedly connected to the right side of the positioning rod 1104. The right side of the limiting rod 14 is movably connected to the inside of the limiting groove 13. A limiting slot 15 is formed inside the cavity 10. A limiting rod 16 is fixedly connected to the right side of the cross bar 1102. The right side of the limiting rod 16 is movably connected to the inside of the limiting slot 15.

[0039] Through the fixing mechanism 11, when replacing the needle head 8, press down the moving rod 1101. The moving rod 1101 drives the cross bar 1102 to move. The cross bar 1102 drives the positioning rod 1104 to move, stably fixing the needle head 8 to prevent loosening and ensuring the normal use of puncture.

[0040] When the present invention is in operation: First, insert the catheter 4 into the inside of the syringe body 1. The return spring force of the compression spring 302 drives the clamping plate 303 to fix the catheter 4, facilitating the pushing and puncturing of the catheter 4. When it is necessary to replace the needle 8, press down the moving rod 1101. The moving rod 1101 drives the cross bar 1102 to move downward. The cross bar 1102 pushes the inclined rod 1103 to move downward. The inclined rod 1103 pushes the positioning rod 1104 to move outward simultaneously. The positioning rod 1104 moves outward along the movement track provided by the limit groove 13. At this time, the needle 8 can be taken out and replaced. After completion, insert it back into the syringe and release the moving rod 1101. The return spring force of the compression spring 1105 enables the positioning rod 1104 to re-insert into the inside of the syringe body 1.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
