Plugging hemostasis device for needle biopsy

The utility model belongs to the technical field of medical instruments, and relates to a needle biopsy plugging hemostasis device which comprises a pushing mechanism, a storage mechanism is installed on the pushing mechanism, and a connecting mechanism is installed on the storage mechanism. The connecting mechanism is divided into two parts, namely a sliding connecting assembly and a rotation limiting assembly, a plurality of clamping claws are installed on the fixing assembly, and when the rotation limiting assembly and the sliding connecting assembly coincide, the sliding connecting assembly and the storage mechanism can form fixed connection, the clamping claws are lifted up, and the clamping claws are clamped in the storage mechanism. And the clamping claw is fixedly connected with the auxiliary device. The specification of the gelatin sponge strip is 2.5 mm * 10 mm after the gelatin sponge strip is released, the gelatin sponge strip is thicker than a puncture needle passage, the diameter of the gelatin
