ISOLATING STRUCTURE FOR EXTERNAL SKELETAL FIXATOR

摘要

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.
