An expandable spinal implant includes a flexible body, an expander component, a fastener and an anti-reverse mechanism. The flexible body includes a base portion and flexible arms each having a free end and a fixed end connecting the base portion. The flexible arms surround an installation space. The expander component is partially in the installation space and exerts pressure on the free ends to move the free ends away from one another. The fastener includes a head portion and a screw portion. The head portion and the expander component are at opposite sides of the base portion. The screw portion passes through the base portion and screwed into the expander component. The anti-reverse mechanism is fixed to the base portion and blocks one side of the head portion located away from the expander component. The anti-reverse mechanism and the expander component are at opposite sides of the base portion.

Expandable spinal implant

A tissue scaffold for use in a tendon and/or ligament is provided, which includes a weave formed by interlacing warp yarns and weft yarns, wherein the warp yarns include a plurality of fibers with an alternative shaped cross section structure, and the weave includes: a main body area with a bioactive component formed on the fiber surface, and a fixed area comprises the weft yarn having a bioceramic material. The tissue scaffold prepared in the present disclosure has the characteristics of stimulating the growth of tissues and inducing tissue repair, effectively improving the ability of tissue regeneration and bone healing, and is beneficial to the reconstruction of the tendon and/or ligament.

Tissue scaffold for use in tendon and/or ligament

The disclosure relates to a spinal intervertebral body fusion device including an adjustable spacer, a first and second pushing piece, and an operative piece. The adjustable spacer includes a first and second supporting plate. The first supporting plate portion is movably installed on the second supporting plate portion. The first and second supporting plate portions form a first and second opening respectively located at two opposite sides of the adjustable spacer. The first pushing piece located at the first opening and is partially clamped by the first and second supporting plate portions. The second pushing piece located at the second opening is partially clamped by the first and second supporting plate portions. The operative piece is movably disposed through the second pushing piece and screwed to the first pushing piece. The operative piece has an annular slot, and the second pushing piece is partially located in the annular slot.

Spinal intervertebral body fusion device

A low-profile offset-type spinal fusion device includes a first screw, a connection base, a nut and a compression part. The first screw has an external thread and a flange. The connection base includes a penetration part and a connection part disposed no higher than the penetration part, and can sleeve the first screw through a first hole of the penetration part to contact the flange with opposite ends of the first screw protruding out of the first hole. The nut, used to engage the first screw, has a bottom surface to contact against the penetration part. When the first screw is installed by penetrating the first hole, the nut and the flange are located to opposite ends of the first hole. The compression part is to screw into a cavity of the connection part for depressing a connecting bar tightly in the cavity.

Low-profile offset-type spinal fusion device

An artificial joint includes a first joint assembly and a second joint assembly. The first joint assembly is adapted to be connected to a first bone and has a first contacting surface, wherein the first contacting surface includes a first convex arc surface, a second convex arc surface, and a third convex arc surface. The second joint assembly is adapted to be connected to a second bone and has a second contacting surface, wherein the second contacting surface is in contact with the first contacting surface and includes a first concave arc surface, a second concave arc surface, and a third concave arc surface, and the first concave arc surface, the second concave arc surface, and the third concave arc surface respectively correspond to the first convex arc surface, the second convex arc surface, and the third convex arc surface.

Artificial joint

An osteo-implant is provided, having a fixing segment and an implant end. The fixing segment is provided with a thread and at least one bone healing chamber. The bone healing chamber is located at a thread root of the thread. The bone healing chamber is a chamber inwardly depressed from a surface of the fixing segment. The fixing segment has a central axis. In the same section of the fixing segment, an area of a section, which is parallel to and passes through the central axis, of the at least one bone healing chamber closer to the implant end is smaller.

Osteo-implant

A bionic fixing apparatus is provided. The bionic fixing apparatus includes a body having a through hole and at least one slit. The through hole penetrates the body from the top surface to the bottom surface to form a top opening and a bottom opening. An inner diameter of the top opening is larger than an inner diameter of the bottom opening. The slit is connected to the bottom opening and extends upwardly from the bottom surface of the body, such that the body has a flexible bottom portion.

Bionic fixing apparatus and apparatus for pulling out the same

A bionic apparatus is provided. The bionic apparatus includes a flexible portion having a plurality of pores, a rigid portion connected with the flexible portion, and a supporting element disposed in the flexible portion. The pore size of each pore is between 50 &#x3bc;m to 500 &#x3bc;m. The flexible portion, the rigid portion and the supporting element are one-piece formed by a additive manufacturing process.

Bionic fixing apparatus

An implant device for osseous integration includes a plurality of connection bars and at least one frame bar. These connection bars are connected with each other to form a three-dimensional (3D) grid structure. The frame bar is connected with at least two of the connection bars to define at least one edge of the 3D grid structure. Wherein, the frame bar has a diameter substantially greater than that of these connection bars.

Implant device for osseous integration

A bionic fixing apparatus is provided. The bionic fixing apparatus includes a flexible portion having at least one trench. The trench is disposed on the surface of the flexible portion and has a first end and a second end. An interval is disposed between the first end and the second end. The trench is disposed for spreading the stress applied on the bionic fixing apparatus and preventing stress concentration and stress shielding.
