摘要:
An anti-reverse apparatus for a trocar and a trocar are provided. The anti-reverse apparatus of the present application includes a latch capable of stopping an end sealing piece from moving reversely, and a loose switch capable of relieving a stopping action exerted by the latch on the reverse movement of the end sealing piece. By pressing the loose switch down, limitation of the latch on the reverse movement of the end sealing piece can be relieved. When the end sealing piece is detachably mounted at a near end of a sleeve in a rotating manner, the latch can stop reverse movement resulting in loosening of the end sealing piece and prevent air leakage or prevent the end sealing piece from loosening from the near end of the sleeve. When the loose switch is pressed down, limitation of the latch on the reverse movement of the end sealing piece can be relieved, and the end sealing piece can be detached from the near end of the sleeve by means of the reverse movement. The trocar of the present application includes the anti-reverse apparatus of the present application, thus improving the reliability of the trocar.
