[0027] The grabbing rod 1 and the built-in straw locking ring 2 movably connected to the grabbing rod 1, the built-in straw locking ring 2 is movably installed with a grabbing rod telescopic frame 4 at the connection point, and the grabbing rod elastic component is installed on the grabbing rod telescopic frame 4; the stone suction component is arranged on the grabbing rod 1, and is threadedly connected to the grabbing rod elastic component, and is used for stone suction to be held and merged in the claws of the grabbing rod elastic component; the stone grabbing and filtering component is installed on the grabbing rod 1, and a stone suction straw hand-held rod 5 is movably installed at the bottom end of the grabbing rod 1, and a locking ring 13 is provided at the straw of the stone suction straw hand-held rod 5, and a straw end 7 is provided at the fixed connection between the stone suction straw hand-held rod 5 and the locking ring 13, and a rubber straw 8 is fixedly connected to the pipe mouth of the straw end 7, which is used for air pressure adsorption on the grabbing rod elastic component to maintain the stone suction state.
[0028] In this embodiment, the stone grabbing rod 3 which is pneumatically telescopically deployed is movably installed inside the grabbing rod telescopic frame 4. The grabbing rod telescopic frame 4 is fixedly connected to the rubber folding cover 10 through the telescopic frame ring 9. The grabbing rod 1 is threadedly buckled on the grabbing rod telescopic frame 4 and the rubber folding cover 10 through the built-in suction tube locking ring 2. The stone suction tube hand-held rod 5 is connected and installed on the grabbing rod 1. The built-in suction tube 11 runs through the grabbing rod 1 and the grabbing rod telescopic frame 4. When the stone grabbing rod 3 is deployed by the existing pneumatic telescopic method, the built-in suction tube 11 runs through the grabbing rod telescopic frame 4 and the inner side of the stone grabbing rod 3 to absorb the stones. When the stone grabbing rod 3 grabs a larger stone, the built-in suction tube 11 can be adsorbed on the larger stone by relying on the adsorption force to prevent the stone grabbing rod 3 from falling off when grabbing the larger stone.
[0029] Please refer to Figure 1 and Figure 2 In this embodiment, the grab rod elastic component includes a telescopic frame ring 9 fixedly mounted on the grab rod telescopic frame 4, and a rubber folding cover 10 is fixedly connected around the ring opening of the telescopic frame ring 9.
[0030] After the grabbing rod telescopic frame 4 is fixedly connected to the rubber folding cover 10 through the telescopic frame ring 9, the stone grabbing rod 3 can rely on the elasticity of the rubber folding cover 10 to perform buffering and pressing when grabbing a larger stone, thereby preventing the grabbing rod telescopic frame 4 and the stone grabbing rod 3 from being directly pressed and inserted into the patient's body, etc., preventing the patient's body from being injured during the stone grabbing and pressing process, and acting as a buffer structure during forceful operation. The open clamp can press and grab the stone multiple times, etc.
[0031] Please refer to Figure 1 and Figure 2 In this embodiment, the grabbing rod elastic component also includes a stone grabbing rod 3 movably mounted on the inner side of the grabbing rod telescopic frame 4. The stone grabbing rod 3 is pneumatically telescopically unfolded to grab stones. The stone suction component maintains the pipeline adsorption state.
[0032] The stone grabbing rod 3 is movably installed on the inner side of the grabbing rod telescopic frame 4, so that the stone suction component is installed on the inner side of the stone grabbing rod 3 and the grabbing rod telescopic frame 4 through a pipeline for adsorption. The stone suction component absorbs smaller stones into the built-in suction tube 11 through the pipeline.
[0033] Please refer to Figure 1 and Figure 3 In this embodiment, the stone suction assembly includes a threaded ring 12 movably mounted on the grabbing rod 1 , and the threaded ring 12 is threadedly connected to the built-in suction tube locking ring 2 .
[0034] The grabbing rod 1 is threadedly connected to the built-in suction tube locking ring 2 through a threaded ring 12, and the built-in suction tube locking ring 2 is threadedly reinforced on the grabbing rod 1 and the threaded ring 12. The built-in suction tube 11 inside the grabbing rod 1 and the threaded ring 12 can be inserted into the inner side of the stone grabbing rod 3 and the grabbing rod telescopic frame 4 to adsorb stones.
[0035] Please refer to Figure 1 and Figure 3 In this embodiment, the built-in suction tube 11 movable inside the threaded ring 12 passes through the built-in suction tube locking ring 2 and the inner side of the grabbing rod telescopic frame 4, and is used for small stone suction to maintain adsorption air pressure on the stone grabbing and filtering assembly.
[0036] The built-in suction tube 11 is inserted into the inner side of the stone grabbing rod 3 and the grabbing rod telescopic frame 4. When adsorbing stones, small stones are sucked through the built-in suction tube 11, pass through the inside of the stone suction tube hand-held rod 5, and enter the stone filter box 6 for filtration. The liquid in the stone filter box 6 enters the suction tube end 7 and the rubber suction tube 8 for adsorption.
[0037] Please refer to Figure 1 and Figure 4 In this embodiment, the stone grabbing and filtering assembly includes a filter screen cover 14 movably connected to the stone filtering box 6, and the filter screen cover 14 is threadedly mounted on the straw end 7.
[0038] The filter screen cover 14 is movably installed inside the stone filter box 6. The filter screen cover 14 is threadedly mounted on the straw end 7. When small stones are sucked through the built-in suction tube 11 and pass through the stone straw hand-held rod 5 to enter the stone filter box 6 for filtration, the straw end 7 uses air pressure to absorb liquid from the small stones. The small stones can be filtered on the filter screen cover 14 to prevent the small stones from being rejected by the patient's body. Relatively small stones can be captured and filtered, reducing the pain felt by the patient during excretion in the later stage.
[0039] Preferably, the stone filter box 6 is connected to the straw end 7 through the filter mesh cover 14, and the air pressure adsorption force of the straw end 7 absorbs liquid from small stones. The small stones can be filtered on the filter mesh cover 14, and the stone straw hand-held rod 5 is threadedly installed on the stone filter box 6 through the locking ring 13, which is convenient for medical staff to threadably disassemble the stone filter box 6 and the stone straw hand-held rod 5 to extract and clean small stones.
[0040] As can be seen from the above, the filter screen cover 14 is threadedly mounted on the straw end 7. When small stones are sucked through the built-in suction tube 11, through the stone straw hand-held rod 5, and enter the stone filter box 6 for filtering, the air pressure adsorption force of the straw end 7 absorbs liquid from the small stones.
[0041] The built-in suction tube 11 runs through the inside of the grabbing rod 1 and the grabbing rod telescopic frame 4. When the stone grabbing rod 3 is unfolded by the existing pneumatic telescopic method, the built-in suction tube 11 runs through the inside of the grabbing rod telescopic frame 4 and the stone grabbing rod 3 to absorb the stone. When the stone grabbing rod 3 grabs a larger stone, the built-in suction tube 11 can be adsorbed on the larger stone by relying on the adsorption force.
