Abstract: A needle removing device includes a seat, a driving assembly, a removal assembly and a lift assembly. The driving assembly is disposed on the seat. The removal assembly has one end thereof connected to one end of the driving assembly away from the seat, and includes a needle winding member and a pressing member. The needle winding member is located on one end of the removal assembly away from the driving assembly. The pressing member is connected to the needle winding member. The lift assembly is disposed on the seat. The driving assembly and the removal assembly are movable relative to the seat via the lift assembly. The needle winding member includes a first rod and a second rod, wherein the first rod and the second rod are adjacently spaced to form a disassembly space. The pressing member includes a first elastic element and a second elastic element.

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.

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 steerable electrosurgical electrode is provided. The steerable electrosurgical electrode comprises a handle, a control element, a first tube, a second tube, a third tube, an electrode and an electrical transmission unit. The handle has a flat area therein, the control element has a plurality of positioning planes and pivotally connects to the handle such that one of the positioning planes rotatably abuts against the flat area, the first tube is positioned inside the second tube and pivotally connected to the control element, the third tube is connected to the second and the first tubes through a first and a second links, respectively, and the electrode is configured at the right end of the third tube. A user may manipulate the control element such that it abuts against the flat area at different positioning planes, to move the first tube inside the second tube, which in turns rotates the third tube and the electrode.
