[0026] The motor 33 drives the rotating plate 31 to rotate, and the rotating plate 31 drives the pair of connecting plates 32 to rotate. The pair of connecting plates 32 drives the pair of clamping plates 2 to move toward the middle. During the movement of the clamping plates 2, they are restricted by the limiting plates 4 and the limiting grooves 41 and can only move horizontally along the limiting plates 4. The clamping plates 2 clamp the needle tip of the abdominal needle, and the needle tip of the pneumoperitoneum needle is located in the clamping groove 21.

The motor 33 drives the rotating plate 31 to rotate in the opposite direction, and the clamping plate 2 releases the needle of the Veress needle, causing the needle to fall.

[0035] Step 4: The needle falls into the collection box 61, and the needle tube is manually taken to another collection area, which realizes the separate recovery of the needle and the needle tube, reduces the involvement of manual labor, and is more practical;

[0036] Step 5: When the collection box 61 is full, lift the collection box 61 upward until the block 7 is completely disengaged from the card slot 71, then remove the collection box 61 and replace it with an empty collection box 61 to continue collecting needles.
