The present invention discloses a surgical device including: an operating lever, which includes two pinching arms that integrate to be a solid tube for pinching the object; an arm hold-down tube, which is a round and hollow tube for containing the said two pinching arms, closing the said two pinching arms for pinching the object; and a puncture tube, which is a round and hollow tube for containing the said two pinching arms and the said hold-down tube, the three tubes form the inter-sleeve structure. The device also includes a connection part for connecting the said puncture tube so that the said puncture tube can connect to the tube with larger diameter to form the puncture stabilizing and balancing tube; and a puncture part, which will protrude or retract via the puncture motion mechanism provided at the said puncture tube, so that the object can be pinched with the said operating lever and the said puncture part will protrude for conducting puncture. The device of the present invention can be used for different minimally invasive surgeries, will not bring about any injury and hazard and can be extensively used for surgeries under the endoscope.
