A flexible spine fixing structure includes a first flexible element and a second flexible element. The first flexible element includes a first flexible part, a first fixing part and a second fixing part. The first fixing part and the second fixing part are respectively connected to two ends of the first flexible part and used for fixing to a first vertebra, and the first flexible part includes a first through hole and a second through hole. The second flexible element includes a second flexible part, a third fixing part and a fourth fixing part. The third fixing part and the fourth fixing part are respectively connected to two ends of the second flexible part and used for fixing to a second vertebra. The second flexible part is disposed by penetrating through the first through hole and the second through hole.

The disclosed is a biodegradable copolymer, an amphiphilic diblock copolymer, composed of a hydrophilic segment and a hydrophobic segment. The hydrophilic segment is an endcapped PEG or derivatives thereof. The hydrophilic segment is a random polymer polymerized of lactone or cyclic C-Cmolecule and lactic acid/glycolic acid. There is no coupling agent between the hydrophilic and hydrophobic segments, and the biodegradable copolymer is formed by one-pot ring-opening polymerization. The biodegradable copolymer can be dissolved in water to form a thermosensitive material having a phase transfer temperature of 25 to 50&#xb0; C., thereby being applied to biological activity factor delivery, tissue engineering, cell culture and biological glue.

A spinal fusion device abutting and fixed between adjacent vertebrae. The spinal fusion device includes a support frame. The support frame has a plurality of extending bodies, each radially extending from a center of the support frame. A predetermined gap exists between every two adjacent extending bodies, receiving a bone graft.

In the manufacturing method of fluoro based polymer composite boards of the invention, which provides a fast process and high efficiency, a suitable amount of water soluble organic solvent is added to a fluoro based polymer suspension during the process of mixing ceramic powder and/or glass fiber to the fluoro based polymer suspension in order to improve the coagulation of the fluoro based polymer and ceramic powder, and to reduce the gelling time. During the process of mixing ceramic powder and/or glass fiber, the fluoro based polymer suspension and the organic solvent, a suitable amount of water can be added to control the ratio between the water and the organic solvent obtained from the mixture. The gelling time of the mixture can thus be reduced. By controlling the ratio between the water and the organic solvent obtained from the mixture, there is still enough time to allow homogeneous mixing after the gelling speed is increased.

Disclosed is a gas injection mold structure for use in the field of gas auxiliary injection molding, comprising a male mold and a gas injection device. The gas injection device includes a head and a cylindrical body extending from the head. The male mold is formed with a cylindrical cell. The cylindrical body has an outer periphery and the cylindrical cell has an inner wall being formed with matching outer and internal threads, respectively, such that the gas injection device is removably threaded into and affixed to the cylindrical cell by means of the cylindrical body. The cylindrical body is formed with a plurality of vertical grooves along an entire length of sides thereof. The head has a lower surface being formed with lateral grooves corresponding to the vertical grooves, such that when the gas injection device is threaded into the male mold, each vertical groove and its corresponding lateral groove jointly form a continuous passage originating from bottom of the cylindrical cell to the periphery of the head, thereby pressurized gas is injected into a cavity through the passage.
