20110071636 | Displacement Leaf Spring and Artificial Intervertebral Disc Containing the Same - A displacement leaf spring and an artificial intervertebral disc containing the same, particularly about the artificial intervertebral disc using the displacement leaf spring to cushion axial compression, wherein the artificial intervertebral disc includes a displacement leaf spring and the displacement leaf spring further includes an upper plate, an inclined plate, and a lower plate. The upper plate has a first breach, and the inclined plate has a first connecting side which connects to one side of the first breach. There is an angle between the inclined plate and the upper plate. The inclined plate has a second breach, and the lower plate has a second connecting side which connects to one side of the second breach. There is an angle between the lower plate and the inclined plate, and the lower plate parallels the upper plate. The artificial intervertebral disc equipped with the displacement leaf spring further comprises a top plate, a bottom plate, a core structure, and a socket structure. The top and bottom plate connect to the bottom of the upper vertebral body and the top of the lower vertebral body respectively. The form of the core structure fits in the socket structure. The core structure and the socket structure are installed between the top and bottom plate to make the artificial intervertebral disc have a wide range of activity angle and capability to cushion the axial compression. | 03-24-2011 |
20110118849 | Modular Hip Joint Prosthesis and Assembling Method Thereof - The invention relates to modular hip joint prosthesis and an assembling method thereof. The modular hip joint prosthesis includes a stem component, a proximal body module and lock component. The proximal body module assembles with the stem component and includes a first curved surface component and a second curved surface, wherein the radius of curvature of the first curved surface component is different from the radius of curvature of the second curved surface component. The lock component is used to encase the first curved surface component and the second curved surface for locking up both components. | 05-19-2011 |
20110264095 | Assisted Positioning Device for Bone Plate - The present invention relates to an assisted positioning device for bone plate, including: a bone plate, a first positioning component and a second positioning component. The surface of the bone plate configured a number of positioning grooves in order to correspond with a number of bone screws provided for the integration. One end portion of the bone plate configures a first positioning slot, and the first positioning slot is containing a gap. When the end portion of the first positioning component combined the first positioning slot, a first positioning pin can be penetrated by a first through slot of the first positioning component, and in line with the gap. The device can actually reduce the size of incision, shorten the healing time after surgery, and have precisely positioning capabilities. | 10-27-2011 |

20100217265 | ANTI-SUBSIDENCE DYNAMIC HIP SCREW - An anti-subsidence dynamic hip screw comprises of a barrel having a connection portion and a tube-type extending portion angled a predetermined angle with the connection portion, and a first long groove and a first limit portion disposed at the inner wall of the extending portion respectively; a lag screw having an inside end disposed threading screw at its outer edge and a outside end with a predetermined length passed through in the extending portion by the way of reciprocation; a second long groove and a second limit portion disposed at the lag screw respectively related to the first long groove and the first limit portion, each first limit portion and second limit portion used for preventing the lag screw from rotating inside the extending portion; a blade piece with a predetermined length simultaneously passed through and retained in the first long groove and the related second long groove; a compressing screw having an inside end screwed with the outside end of the lag screw and an outside end retained in the outside end of the extending portion. The above structure is not only easy to assembly, especially for the effect of decreasing the subsidence of the femoral head, but also makes the effect more obvious when using for the hip fracture of the osteoporosis body. | 08-26-2010 |
20100217389 | GRAFT ATTACHMENT DEVICE FOR LIGAMENT RECONSTRUCTION - The present invention discloses a graft attachment device for cruciate ligament reconstruction comprises a body having a screw portion with a threading area on the front end of the body, a connection member disposed on the front end, a gap formed between the front end and a predetermined portion of the body adapted for a rope-type member pass through, a pivoting member pivoted on the rear end of the body with its front end, the rear end of the pivoting member having a juncture portion for fixing a ligament, thereby the device could be screwed and fixed on a bone when rotating the device, and seamed a ligament on the rear end of the device. | 08-26-2010 |
20100318028 | INSERTION APPARATUS FOR ALIGNING CAGE OF INTERVERTEBRAL FUSION - The present invention discloses an insertion apparatus for aligning cage of intervertebral fusion comprising a dilatation set having a first and a second dilatation barrel formed with corresponding cross-sections and sleeved in series; a guiding set having a first and a second guiding tube inserted in the respective dilatation barrels, a guiding hole disposed adjacent to one end of the second guiding tube, a smooth curved surface inside the guiding hole communicated with a shaft hole disposed in the second guiding tube; an insert set having a leading rod inserted in the second guiding tube, a push rod pivoted at the leading rod; and a fusion cage disposed in the second guiding tube, an arc portion of the fusion cage passed through the second guiding tube along the smooth curved surface and the guiding hole, so as to shorten surgery time and position the fusion cage more exactly. | 12-16-2010 |
20130046347 | BENDABLE BONE PLATE FOR EXTERNAL FIXATION - The present invention relates to a bendable bone plate for external fixation, comprising a main body made of flexible materials, wherein the end of the main body has a larger surface area. There are several perforations running the length of the bone plate body and more located on the larger proximal end. The characteristics of the present invention, a bendable bone plate for external fixation, deal with remote end fracture, proximal end fracture, central fracture or comminuted fracture of an upper limb long bone. Furthermore, the bendable bone plate for external fixation can be manipulated for averting the nerve plexus and traumatic wounds, allowing for external fixation surgery. | 02-21-2013 |
20130253511 | MULTIPLE AXES EXTERNAL BONE FIXING MEMBER - An external bone fixing member includes an external reconstruction plate to replace the conventional large external support frame to reduce the volume of the external fixing member and the external bone fixing member is cooperated with a screw which is angle adjustable so as to meet requirements of fixation of the fractured bones (limb bones) at different positions or comminuted fractures. The use of the screw is further cooperated with the reconstruction plate to reinforce the stability of the connection between the reconstruction plate and the screw to prevent the screw from withdrawing, moving, angle changing or movement of the reconstruction plate. | 09-26-2013 |
