Abstract
A trocar includes a puncturing device and a sleeving component. The puncturing device includes a base and a puncturing portion. The puncturing portion includes a bump and a tip. The bump extends from an outer surface of the puncturing portion radially. The sleeving component includes a gas pressure base, a first tube assembly, a second tube assembly, and a fixation base. The second tube assembly is retractable. The fixation base is fixed to the second sleeving end and includes a guiding groove and a key groove. The guiding groove communicates the key groove. While the bump of the puncturing device is entered through the guiding groove, and the puncturing device is rotated to have the bump be in the key groove, the puncturing device is secured to the fixation base, and the puncturing device drives the fixation base to move along an elongated direction of the puncturing device.
