摘要： The present invention relates to a device for preparing three dimensional (3D) nanofibers (blended or coaxial) materials by electrospinning. An automatic nanofiber collector device is used to control the porosity, pore size, crystallinity, geometry, the layer number and thickness of formed nanofibers. The automatic nanofiber collector device includes: (1) a collector platform; (2) a non-conductive device used to fix the collector device; (3) a plurality of electro-conductive wires or needles being pierced through the collector platform with various heights, and (4) the ends of the needles (at bottom) are wired and controlled by a microcontroller, providing forward, stand and backward movements for attached needles. The desired 3D nanofiber scaffold structures can be tailored by the micro-stepping programmable motor controller by changing the pattern and velocity of needle movement, generalized or selective needles movements, as well as intermittent versus continuous movement.

摘要： The present invention provides a fingerstall-cannulated guide device for accurate and efficient guide wire placement for antegrade femoral nailing systems. The said device comprises a fingerstall with a cannulated guide connected with or without a threaded guide wire. Using this device, surgeons can determine the entry point for the guide wire fast and accurately by tactile hand-eye coordination. After correct entry point is obtained, the guide wire is advanced and the fingerstall-cannulated guide can be easily detached. The device and method can accomplish the following: (1) reduction of the surgery time; (2) reduction of the radiation exposure times, and (3) reduction of the soft tissue damage during surgery. The device is also beneficial for use in fastening together any or all portions of bone surrounding a fracture site.
