A three-dimension-extending intramedullary nail, which is made of memory metal, comprises a rod-shaped body, two distal ends formed at two ends of the rod-shaped body, and a plurality of bent portions on the rod-shaped body and between the two distal ends. Each of the bent portions is bent around a curve center and defines a reference plane whereon the bent portion and the curve center are disposed, and at least two of the reference planes of the bent portions are different. The three-dimension-extending intramedullary nail can be implanted into marrow cavity in one time and is applicable to the treatment of various fracture patients. In addition, the three-dimension-extending intramedullary nail is flexible and can be bent according to the curvature of the marrow cavity, thereby being applicable to the marrow cavity of different length. Moreover, the three-dimension-extending intramedullary nail can also form axial deformation to apply pressure upon fracture surface, thus to pull and pressure the fracture surface and promote bone regeneration and shorten fracture healing time.

A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and a thermoplastic polymer for molecular scale healing is disclosed; the composition has the ability to resolve structural defects by a bio-mimetic close-then heal process. In use, the shape memory polymer serves to bring surfaces of a structural defect into approximation, whereafter use of the thermoplastic polymer for molecular scale healing allowed for movement of the thermoplastic polymer into the defect and thus obtain molecular scale healing. The thermoplastic can be fibers, particles or spheres which are used by heating to a level at or above the thermoplastic's melting point, then cooling of the composition below the melting temperature of the thermoplastic. Compositions of the invention have the ability to not only close macroscopic defects, but also to do so repeatedly even if another wound / damage occurs in a previously healed / repaired area.

The invention provides a multifunctional scenic area indication device capable of collecting garbage. The multifunctional scenic area indication device comprises a luminous plate and an isolation block. A base is of a circular cake-shaped structure. Two umbrella storage holes are formed in the top end face of a garbage can storage frame, and the bottom of a supporting column is arranged on the topend face of the garbage can storage frame. A garbage can is of a cylindrical hollow structure, a garbage can top cover is arranged on the top of the garbage can, and a garbage collecting port is formed in the front end face of the garbage can top cover. Two umbrella hanging frames are arranged, and one end of each umbrella hanging frame is of a circular-ball-shaped structure. When rain suddenly happens in the scenic area, rain sheltering appliances can be provided for scenic area visitors, the situation that rain wets personnel clothes, and the later scenic area viewing effect of personnel isinfluenced is avoided; and in cooperation with the arrangement of umbrella storage grooves in the garbage can, umbrellas can be better stored and fixed, the area occupied by the umbrellas is reduced,and the situation that due to wind generated in the scenic area, the umbrellas are blown away from the device, and the later umbrella usage effect is influenced is avoided.
