Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a gastrointestinal polyp specimen collector for nursing use. Background Technology

[0002] Gastrointestinal polyps are a general term encompassing both gastric and intestinal polyps. Before a definitive pathological diagnosis of the protruding mass within the gastrointestinal tract, they are all referred to as polyps. Gastrointestinal polyps are a relatively common digestive system disease, occurring singly, multiple times, and in some patients, even hundreds of polyps. After removal, polyps need to be sent for examination and case analysis; therefore, a polyp specimen collector is required to collect the polyps for unified testing.

[0003] Chinese Patent Application No. CN201921069546.7 discloses a colonoscopy specimen collection device, including a collection wheel, a support, an air inlet connector, and an air outlet connector. The collection wheel has 4 to 8 specimen collection chambers distributed circumferentially. The air inlet connector, specimen collection chambers, and air outlet connector are connected in sequence to form an airflow passage. The support is hinged to the rotation center of the collection wheel so that the specimen collection chambers in the gas passage are replaced when the collection wheel rotates around the support.

[0004] However, this collection device connects the air inlet to the external interface of the colonoscope and the air outlet to the negative pressure suction tube. The removed polyps are suctioned out by the negative pressure and remain in the specimen collection chamber. Each polyp collected requires only one rotation of the collection wheel, improving efficiency. However, there is no sealing between the air inlet / outlet and the specimen collection chamber, making air leakage highly likely and preventing the polyps from being suctioned out by the negative pressure. Therefore, we propose a new gastrointestinal polyp specimen collector for nursing use. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-5This utility model provides a technical solution: a gastrointestinal polyp specimen collector for nursing use, including a collection wheel 1, an air inlet connector 2, and an air outlet connector 3. The collection wheel 1 has several collection chambers 4 arranged around its circumference. A filter screen 44 is provided in the middle of each collection chamber 4, which can trap removed polyps within the collection chamber 4. Fixing plates 5 are fixedly connected to both ends of each collection chamber 4. Sealing grooves are formed on the side walls of the two fixing plates 5 that are far apart from each other, and energy-storing sealing rings 6 are provided within the sealing grooves. Two symmetrically distributed receiving grooves 41 are formed at both ends of each collection chamber 4. A locking block 42 is slidably provided within each receiving groove 41, and the locking block 42 abuts against the receiving groove 41. With a first spring 43, both the air inlet connector 2 and the air outlet connector 3 are pressed into the collection chamber 4. The fixed extrusion head 21 will press the locking block 42. After being subjected to force, the locking block 42 will gradually retract into the receiving groove 41 and compress the first spring 43. When the fixed extrusion head 21 presses against the fixed plate 5, the locking block 42 loses the extrusion force and is pushed by the first spring 43, locking between the fixed extrusion head 21 and the movable extrusion head 22, so that the fixed extrusion head 21 is fixed and closely attached to the fixed plate 5, thereby applying pressure to the energy storage sealing ring 6. The energy storage sealing ring 6 is compressed and forms an outward tension, thereby filling the sealing groove, so that the air inlet connector 2 and the air outlet connector 3 are sealed with the fixed plate 5, preventing air leakage.

[0024] A fixed extrusion head 21 is fixedly fitted at one end of the air inlet connector 2 and the air outlet connector 3. After the fixed extrusion head 21 is pressed against the fixed plate 5, it will be locked by the locking block 42, so that it always applies pressure to the energy storage sealing ring 6. A movable extrusion head 22 and a pressing ring 23 are slidably fitted on the air inlet connector 2 and the air outlet connector 3. A connecting rod 24 is fixedly connected between the movable extrusion head 22 and the pressing ring 23. After the polyp is collected, the pressing ring 23 is pushed, and the movable extrusion head 22 can be pushed closer to the fixed extrusion head 21 through the connecting rod 24. The movable extrusion head 22 will squeeze the locking block 42. After being squeezed by the movable extrusion head 22, the locking block 42 will gradually retract into the receiving groove 41. When the movable extrusion head 22 and the fixed extrusion head 21 are in contact, the locking block 42 will no longer obstruct the fixed extrusion head 21, so that the air inlet connector 2 and the air outlet connector 3 can be separated from the collection chamber 4.

[0025] A hollow rotating shaft 7 is rotatably inserted at the center of the collecting wheel 1. A partition 71 is fixedly connected to the center of the hollow rotating shaft 7. Two symmetrically distributed movable plates 72 slide inside the hollow rotating shaft 7. A connecting rod 73 is fixedly connected to the side wall of the movable plate 72 away from the partition 71. Two symmetrically distributed guide rails 731 are fixedly connected to the rod wall of the connecting rod 73. The other end of the connecting rod 73 extends to the outside of the hollow rotating shaft 7. A connecting plate 74 is fixedly connected to both the air inlet connector 2 and the air outlet connector 3. The lower end of the connecting plate 74 is fixedly connected to the connecting rod 73. A second spring 75 is provided between the air inlet connector 2 and the partition plate 71. When the air inlet connector 2 and the air outlet connector 3 are inserted into or removed from the collection chamber 4, the moving plate 72 will slide in the hollow rotating shaft 7. With the help of the adapter rod 73 and the connecting plate 74, the air inlet connector 2 and the air outlet connector 3 can be limited. In addition, the air inlet connector 2 and the air outlet connector 3 are provided with moving space. Two guide grooves adapted to the guide rail 731 are opened at both ends of the hollow rotating shaft 7. The guide grooves guide the guide rail 731, so that the adapter rod 73 will not drive the air inlet connector 2 and the air outlet connector 3 to rotate.

[0026] It should be noted that this utility model is a gastrointestinal polyp specimen collector for nursing use. In use, the air inlet connector 2 is connected to the external interface of the colonoscope, and the air outlet connector 3 is connected to the negative pressure suction tube. Then, both the air inlet connector 2 and the air outlet connector 3 are pressed into the collection chamber 4. The fixed squeezing head 21 squeezes the locking block 42. Under pressure, the locking block 42 gradually retracts into the receiving groove 41 and compresses the first spring 43. When the fixed squeezing head 21 presses against the fixed plate 5, the locking block 42 loses its squeezing force and is pushed by the first spring 43, locking between the fixed squeezing head 21 and the movable squeezing head 22. This fixes the fixed squeezing head 21 tightly against the fixed plate 5, thereby applying pressure to the energy storage sealing ring 6. The energy storage sealing ring 6, under pressure, forms outward tension, thus filling the sealing groove and sealing the air inlet connector 2 and the air outlet connector 3 with the fixed plate 5, preventing... To prevent air leakage, after securing the air inlet connector 2 and air outlet connector 3, the surgery is performed. The cut polyp will be sucked out by negative pressure and remain in the filter screen 44 of the collection chamber 4. Then, push the pressing ring 23, which pushes the movable squeezing head 22 towards the fixed squeezing head 21 through the connecting rod 24. The movable squeezing head 22 will squeeze the locking block 42. After being squeezed by the movable squeezing head 22, the locking block 42 will gradually retract into the receiving groove 41. When the movable squeezing head 22 and the fixed squeezing head 21 are in contact, the locking block 42 will no longer obstruct the fixed squeezing head 21. At this time, the second spring 75 pushes the moving plate 72 to move, so that the adapter rod 73 drives the air inlet connector 2 and air outlet connector 3 to disengage from the collection chamber 4 through the connecting plate 74. Then, rotate the collection wheel 1 and insert the air inlet connector 2 and air outlet connector 3 into another collection chamber 4 to remove the polyp again.
