Abstract: A bone implant to be disposed between a first bone section and a second bone section is disclosed. The bone implant includes a body structure, a plurality of through-hole structures and an extended channel structure. The body structure has a first end surface to be connected to the first bone section and a second end surface to be connected to the second bone section. The plurality of through-hole structures are disposed in the body structure, pass through the first end surface and the second end surface and have a through-hole axis. The extended channel structure is disposed in the body structure, wherein the extended channel structure enables a new bone section to grow along a direction other than the through-hole axis between the first bone section and the second bone section.

Abstract: An intervertebral implant is a porous structure formed of a plurality of metal balls, and the intervertebral implant includes a bone support area and a bone growth area. The bone support area and the bone growth area each have a plurality of connecting holes, and a porosity of the bone support area is smaller than that of the bone growth area.

Abstract: A supporting instrument with a modular intramedullary nail includes a plurality of intramedullary nails and a coupling module.

Abstract: An endoscope controlling device includes a rigid tube mounted to an end face of a base and in communication with a compartment in the base. A positioning groove is formed in an inner periphery of the base and includes a bottom wall having a slot. A linear displacement control module includes a control member and a movable board. The control member is aligned with a through-hole in a periphery of the base. The control member controls longitudinal movement of the movable board in the compartment along a longitudinal axis of the base via a driving gear. An optical element receiving drum is mounted to the movable board. A rotational movement control module is mounted around the optical element receiving drum and received in the positioning groove of the base. A portion of the rotational movement control module is extended through the slot and exposed outside of the base.

Abstract: A femur supporting device includes a rod having an insertion groove and a fixing through-hole. Each of the insertion groove and the fixing through-hole extends through an outer periphery of the rod. An insert is engaged in the insertion groove of the rod. A first fastener is engaged with the fixing through-hole of the rod. The femur supporting device provides enhanced stability.

Abstract: An interbody cage includes a substrate having a plurality of curve slits, with each of the curve slits having a plurality of sections. A plurality of deformable ribs is formed, with each deformable rib between any adjacent two of the curve slits and having a first end and a second end. The first and second ends of each deformable rib respectively connect with two opposite lateral bars of the substrate, and a plurality of folds is formed on the plurality of deformable ribs in places adapted to be bent. In use, any adjacent two of the deformable ribs are capable of being bent to depart from each other to define a filling room.

Abstract: An interbody cage including a substrate and a plurality of through holes is disclosed. The substrate has a plurality of curve slits, with each of the curve slits having a plurality of sections, wherein a plurality deformable ribs is formed, with each deformable rib between any two curve slits and having a narrow part and a wide part. The plurality of through holes is formed in the wide part of the deformable rib. In use, any adjacent two of the deformable ribs are capable of being bent to depart from each other to define a filling room.

Abstract: An endoscope includes a tube having including a compartment extending in a longitudinal direction. A flexible strip has a diameter smaller than a diameter of the compartment. The flexible strip is received in the compartment and slideable relative to the tube in the longitudinal direction. The flexible strip is made of a super elastomer having an original shape before deformation. The flexible strip is capable of restoring the original shape after larger deformation. An image capturing module is mounted to the flexible strip. The image capturing module can transmit light beam and capture images.

Abstract: 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.

Abstract: A spinal implant structure includes a hollow cylinder and a biodegradable polymer membrane. The hollow cylinder is implanted in a bone damaged part of human vertebra. The biodegradable polymer membrane is formed to a part of a surface of the hollow cylinder. Thus, the biodegradable polymer membrane blocks invasion of soft tissues, and then the bone fillers integrated with vertebra are maintained without loss.
