A surgical device includes a surgical instrument and a surgical impactor. The surgical instrument includes a connector whereon a notch is formed. The surgical impactor is configured to be connected to the surgical instrument and includes a shaft, an engaging head, a lever and an operating component. The engaging head is disposed on the shaft for engaging with the connector. The lever is movably disposed on the shaft for engaging with the notch. The operating component is movably disposed on the shaft and includes a wedge-shaped portion movably located between the lever and the shaft. The wedge-shaped portion drives the lever to engage with the notch and eliminate gaps and tolerances between the lever and other structures, including the lever and the notch, during movement of the wedge-shaped portion to a locked position, so as to provide a shock-absorbable and releasable connection between the surgical instrument and the surgical impactor.
