The present invention provides a method for establishing a biomimetic nerve graft model for nerve fascicles of the extremities, which comprises the steps of: establishing a database of fascicles structures from nerve fascicles of the extremities with an imaging technique; obtaining information of a defective nerve trunk to be repaired of the extremities; and matching and fitting the information of the defective nerve trunk to be repaired of the extremities with/to the data in the database of fascicles structures, to establish a biomimetic nerve graft model that conforms to the characteristics of fascicles microstructure for nerve fascicles of the defective nerve trunk. In the present invention, the imaging technique and clinical data are fully utilized, to establish a biomimetic nerve graft model conforming to the characteristics of fascicles microstructure for varying types of detects, thus providing more accurate model information for repair of nerve trunk defects in the extremities.

The present invention relates to fields of clinical application of nerve defect repair and the medical three-dimensional (3D) printing technology, and provides an integrated visualization method for three-dimensional (3D) reconstruction of internal structure of human peripheral nerves. The method comprises the following steps: obtaining human peripheral nerves, preparing nerve specimens ex vivo by staining with an iodine preparation in combination with a freeze-drying method; scanning the pretreated peripheral nerves using Micro CT to acquire lossless two-dimensional images, and performing binarization processing to the two-dimensional images, then conducting image segmentation based on textural features to acquire images of nerve fascicles; finally, reconstructing the segmented images into a visualization model by using a supercomputer.

A multi-function shower head provides three water flower levels in response to three watering modes and comprises a low-flow controlling valve and a water flower generator such that the water flow passes through water flower generator to result in a centrifugal force, and then passes through a plurality of tunnels and a path to spray water, obtaining low-flow and strong water flower. Thereby, a water saving and strong flowing purpose of the shower head is achieved.
