Abstract: A trocar set includes a handle portion, a first sleeve, a second sleeve, and a gasbag. The handle portion includes a grip, a connection part, and a first gas valve. The connection part extends from the grip and includes an assembling channel. The first gas valve is connected to the connection part and communicates with the assembling channel. An assembling end of the first sleeve is assembled to the connection portion. A sleeving end of the first sleeve is provided with a first opening. The second sleeve is retractably connected to the sleeving end of the first sleeve. A sleeve wall of the second sleeve is provided with a second opening. The gasbag is connected to an end of the second sleeve away from the sleeving end and corresponds to the second opening. The design of the retractable sleeves is benefit to perform operation.

Abstract: A trocar set includes a handle portion, a first sleeve, a second sleeve, a gas tight assembly, and a pull band. A connection part of the handle portion extends from a grip and includes an assembling channel. The first sleeve includes an assembling end, a sleeving end, a first outer sleeve wall, and a fastening component. The assembling end is assembled to the assembling channel, and the fastening component is disposed at the sleeving end and contacts the first outer sleeve wall. A sleeving end of the second sleeve is inserted into the receiving end, and the second inner sleeve wall contacts the fastening component. A gas tight sleeve of the gas tight assembly encloses the receiving end and the blocking component. An outer wall of the gas tight sleeve is provided with a plurality of crossing channels. The pulling band crosses the crossing channel.
