An implanting apparatus and an operating method thereof are provided. An implanting apparatus used for implanting an intervertebral cage into a location between two adjacent vertebral bodies, wherein the implanting apparatus comprises a sleeve and an extension member. The extension member has a rod and a coupling column, wherein the rod is screwed inside the sleeve, the coupling column is connected to one end of the rod and exposed outside the sleeve, and the axial direction of the coupling column is substantially perpendicular to that of the rod. When one end of the coupling column is disposed on an inner arc surface of a connecting portion of the intervertebral cage and the rod is rotated with respect to the sleeve, the distance between the coupling column and the sleeve is decreased so as to clamp the connecting portion of the intervertebral cage between the coupling column and the sleeve.

Implanting apparatus and operating method thereof

A bone plate structure adapted to fix a bone in an affected part is provided. The bone plate structure includes first and second bone plates. The first bone plate has a first stacking portion and a first extending portion and is adapted to be moved onto the bone through a wound of the affected part. The second bone plate has a second stacking portion and a second extending portion and is adapted to be moved onto the bone through the wound. When the first and second bone plates are located on the bone, the second bone plate is adapted to be moved relatively to the first bone plate, such that the first and second stacking portions are stacked with each other and the first and second extending portions are expanded relatively. A surgery device and a method for bone plate implant suitable for the bone plate structure is also provided.

Bone plate structure, surgery device and method for bone plate implant

An apparatus for anulus fibrosus repair includes a shaft, a pair of curved suturing needles mounted in parallel on the shaft, and a rotational driving mechanism connected to the shaft, which is configured to rotate the shaft and the pair of needles about a rotation axis of the shaft. Each needle includes a substantially semi-annular body having a proximal end, a distal end, an inner periphery, and an outer periphery, and an arm extending radially inward from the proximal end, in which a concavity is formed in the body proximate to the distal end extending in a direction away from it. Also disclosed is a suturing technique associated with use of the repair apparatus.

Spinal disc anulus repair method and apparatus

A spinal fixation assembly includes a pedicle rod and pedicle screws which secure the pedicle rod to the spine. Each pedicle screw includes a head configured to receive a portion of the pedicle rod, and a threaded portion extending from a first end of the head and configured to engage a vertebra. The pedicle rod is secured to the head by a fastener. The head includes a breakaway region that defines a location in which at least a first portion of the head can be easily separated from the remainder of the head upon application of sufficient force to the first portion. A minimally invasive method of implanting the spinal fixation assembly is disclosed.

Minimally invasive spinal stabilization method

A spinal cage is provided to be implanted in an intervertebral disc space. The spinal cage includes a first segment and a second segment movably connected with each other. The first segment is slidable with respect to the second segment, so as to elongate the spinal cage from a retracted state to an extended state.

Spinal cage and implanting method thereof

An intervertebral cage, an implanting apparatus and an operating method thereof are provided. The intervertebral cage for being implanted between two adjacent vertebral bodies includes a body and a connecting portion. The body has a lateral convex surface, an inclined surface, a lateral concave surface and a connecting surface connected sequentially. The connecting portion includes a main portion and a protrusion. The main portion connected to the connecting surface has a through hole. The protrusion is protruded from the main portion into the through hole to form first and second inner arc surfaces. The maximum width of the intervertebral cage is a distance between first and second lines. The first and second lines are substantially parallel to a tangent line of the lateral convex surface and the first line, respectively. The distance between the inclined surface and the first line decreases gradually along a direction away from the connecting portion.

Intervertebral cage and implanting apparatus and operating method thereof

Minimally invasive spinal stabilization system

A method for filling a bone defect in a subject in need thereof is disclosed. The method includes heating a bone cement composition at a first temperature where the bone cement composition is fluidic, and delivering an effective amount of the fluidic bone cement composition at a second temperature to the bone defect thereby filling the bone defect and allowing the fluidic bone cement composition to solidify, the second temperature being sufficiently high for maintaining the bone cement composition fluidic without causing thermal necrosis. Also disclosed are systems for carrying out the method.

Injectable thermoplastic polymers for biological tissue repair

An apparatus for inserting an intervertebral fusion cage includes a dilatation set, a guiding set and an insert set. The dilatation set includes first and second dilatation barrels non-rotationally and telescopically connected to each other. The guiding set includes first and second guiding tubes provided around the first and second dilatation barrels. The second guiding tube includes a guiding hole defined therein and a smooth arched face formed thereon in the guiding hole. The insert set includes a leading rod inserted in the second guiding tube and a push rod pivotally connected to at the leading rod. The intervertebral fusion cage is located in the second guiding tube. The fusion cage is movable out of the second guiding tube along the smooth face and the guiding hole to shorten surgery time and position the fusion cage precisely.

Insertion apparatus for aligning cage of intervertebral fusion

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.
