lower end surface of the storage cavity 99, the ejection block 37 just ejects from the ejection cavity 42, causing the surgical instrument to move to the right, when the ejection block 37 ejects the surgical instrument into the storage cavity 99, the upper end surface of the lifting plate 32 is not yet in contact with the ejection block 37, at this time, the conveying motor 21 is reversely rotated, causing the ejection block 37 and the lifting plate 32 to return to the initial positions, and the cleaning motor 2 is reversely rotated, causing the entry lever 55 to move to the right, at this time, the valve plate 57 is forced to compress the spring 58, so that the entry rod 55 can continue to move to the right, after the entry rod 55 is out of contact with the valve plate 57, the valve plate 57 returns to the original state, and finally, the entry rod 55 and the sealing plate 50 return to the original position, and the medical staff can take out the surgical instrument through
