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.

An oral dilator includes a first body, a second body, a rotary member, and a positioning member. The first body includes a housing and a first duckbilled element. The second body includes a second duckbilled element corresponding to the first duckbilled element. The rotary member drives the second body to rotate. The positioning member is on the first body and selectively locks or unlocks the relative position between the first duckbilled element and the second duckbilled element when the second duckbilled element is driven to rotate by the rotary member.

A trocar set includes a handle portion, a first sleeve, a second sleeve, and a gas tight assembly. The handle portion includes a grip, a connection part, and a second gas valve. The connection part extends from the grip and includes an assembling channel. The second 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 part. The second sleeve includes a receiving end, wherein the sleeving end is inserted into the receiving end. The gas tight assembly is fixed to the second sleeve and includes a gas tight sleeve and a gas tight ring. The gas tight sleeve encloses the receiving end, and the gas tight ring is pressed by the gas tight sleeve to be tightly attached to the first sleeve.

Trocar set

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.

A tissue culturing method includes following steps: providing a chopped gametophyte, generating calluses by culturing the chopped gametophyte, and performing apogamic regeneration of sporophytes, by culturing the calluses in a culture fluid to develop the sporophytes from the calluses. The present invention also provides a tissue culturing method of ferns and an explant.

A racket is described, with a center of gravity thereof being approximate to a center of a rubber sheet of the racket, and a center of gravity that moves approximately to the center of rubber sheet and is located in a high ball-strike area. The racket has a substantially triangular blade. The blade comprises a head, a neck and a handle. The head becomes gradually narrower from front to back of the head, and the handle can further be lightened. The center of gravity of the racket can thereby move forward to the center of the rubber sheet to enhance attack and defense abilities of the racket, and reduce shock.

A power-saving driving device for treading the pedals of a bicycle is disclosed. Thereby, the driver may use a smaller force to tread a bicycle so that a higher efficiency is provided. The power-saving device comprises two crank axles. The two crank axles are fixed to a gear box. Two spur gears are engaged to the gear box, and two free wheels are installed at an exterior of the gear box. The two spur gears and two free wheels are connected to the two crank axles. The two free wheels are connected through a chain; and a chain wheel and a bearing are connected to the crank axles. Thereby, the forces from the right and left legs can be outputted effectively. The driving of a bicycle and the power necessary are improved. Therefore, the driver treads the pedals with a smaller depth and thus the physical consumption is reduced.
