A slit-type scraper device includes: a body, a first scraper portion, a cover, a second scraper portion, an air pressure through hole and a side cover unit. The body includes a groove and a slit portion abutting against the groove. The first scraper portion is abutting against the slit portion. The cover includes a plate portion. The second scraper portion is abutting against the plate portion, wherein the position of the second scraper portion is corresponding to the first scraper portion. The air pressure through hole is disposed on the body, in communication with the groove, and adapted to connect an air pressure connection member to input air pressure. The side cover unit is adapted to form an ink storage space between the plate portion and the groove, and form an ink output slit between the slit portion and the plate portion.

The present invention relates to an external skeletal fixator, which comprises a fixing member and a stereoscopic hood. The fixing member is disposed on a first end surface of the stereoscopic hood. The diameter of a second end surface of the stereoscopic hood is greater than that of the first end surface of the stereoscopic hood. When the stereoscopic hood is disposed to a pin passing through a skin tissue and a bone tissue, the second end surface of the stereoscopic hood is against the skin tissue surrounding a pin-skin interface and thus covering the stereoscopic hood over the pin-skin interface. The first end surface and a sidewall of the stereoscopic hood do not contact the pin-skin interface and the skin tissue around. Thereby, the contact area between the isolating structure and the pin-skin interface is reduced and the isolating structure blocks external germs from entering via the pin-skin interface.

The present invention provides a multi-spiral optical device, which comprises a base and a plurality of spiral channels. The plurality of spiral channels are formed on the base and include a first port and a second port, respectively. The plurality of first ports are located at the center of the base; the plurality of second ports are located at the periphery of the base. Thereby, the multi-spiral optical device can form a light concentrating device. In addition, a fluid can be filled to or drawn from one or more of the plurality of spiral channels for switching the optical state of the multi-spiral optical device. By filling or drawing the fluid to or from the plurality of spiral channels selectively, they can be switched to a light-pervious, a sheltering, or a light-concentrating state according to users requirements.
