摘要： A bone plate is provided for fixation of spaced vertebra. The bone plate has at least one through passage for securing the plate to bone with a bone fixation screw. The threaded shaft of a bone fixation screw is inserted through a bushing located in the through passage of the bone plate and the screw is thereby threadably secured to the underlying bone and the bushing is then compressed inward against the head of the screw with cams that are actuated by rotating the bushing in the through passage whereby the screw is locked relative to the bone plate. The bushing is not only compressed inwardly against the head of the screw but is also compressed downwardly by the cams into a seat to clamp separate elements of the bone plate together.

摘要： A bone fixation assembly which includes a fixation plate having a through passage and a fastening screw having a threaded shaft for insertion through the passage and thereafter threadable insertion into underlying bone. The screw head has substantially frustospherical shaped side surfaces. A bushing is provided and has an annular cup shaped side wall defining an upwardly open interior bowl for receiving the screw head. The bushing has annularly spaced slots in its side wall which depend downwardly from its upper end for allowing inward compression of the side wall at the upper end. A centrally located screw shank passage is provided in the lower end of the bushing to prevent passage of the screw shank. The bushing bowl is further configured and dimensioned for polyaxial rotation of the screw head in the bowl and for preventing back out of the screw head when the side wall is compressed inwardly. The through passage of the bone plate is further configured and dimensioned to downwardly receive the bushing therein for inwardly compressing the bushing about the screw head and an annular recess is provided in the through passage which receives the upper annular end of the bushing under compression with a snap fit whereby the screw head is retained in the bowl and is thereby prevented from backing out. The screw head is expandable for thereby locking the screw relative to the bone fixation plate.

摘要： Vertebra bodies in the human spine are stabilized through the use of minimally invasive surgery for the implantation of an elongate implant plate assembly having spaced first and second screw receiving socket elements which are configured for respective attachment to first and second spaced vertebra with the aid of bone fixation screws and these elements are slidably received with respect to each other for adjustably changing the distance between the screw receiving socket elements. A lock assembly is also provided for selectively locking the first and second screw receiving elements from further relative sliding. An elongate insertion tool is releaseably secured to the plate assembly, and the insertion tool is configured for manipulating the plate assembly as a whole and for remotely manipulating the screw receiving socket elements for adjusting the distance therebetween. The plate assembly is inserted through an incision and manipulated and advanced with the insertion tool to provide minimally invasive insertion, and after fixation of the implant assembly with bone fixation screws is further utilized by remote manipulation to adjust the degree of compression on the vertebrae, and thereafter the implant is locked in position to prevent further relative movement between the screw receiving elements of the plate assembly.

摘要： A cervical compression plate assembly having screw receiving elements at opposite ends that are configured for engaging bone fixation screws extending from respective vertebral elements. The assembly permits the distance between the screw receiving elements at opposite ends to be shortened but prevents the distance from increasing. A spring mechanism is housed within the plate assembly and is configured for continuously urging the screw receiving elements at opposite ends together for thereby providing continuous compressive loading on bone graft material disposed between the vertebral elements.

摘要： A bone fixation screw includes a threaded screw shank and a screw head having upper and lower ends. The screw head lower end is secured to a proximal end of said screw shank. The screw head has substantially frustospherical shaped side surfaces and is split into segments at one of the ends. The head is radially expandable at the one end. An expansion screw is centrally received in the screw head. An interface between the expansion screw and the screw head forms a cam mechanism for expanding the screw head upon axial rotation of the expansion screw.

摘要： A dosimetry probe for monitoring light irradiation dosages and for providing irradiance measurements to monitor the application of light during a phototherapy procedure. The dosimetry probe includes a light delivery optical fiber operable to transmit optical radiation to target tissue and a plurality of dosimetry optical fibers substantially coextensive with the light delivery optical fiber, the distal ends of each of the dosimetry optical fibers arranged at a different axial distance from the light delivery optical fiber to provide irradiance measurements at a number of different axial distances. The dosimetry probe may include a safety feedback optical fiber to monitor the intensity of the treatment light independent of the influence of the optical properties of the target tissue. The dosimetry probe may also include a source dosimetry optical fiber for carrying a modulated dosimetry light signal, which can be selectively detected by means of frequency lock-in technology.

摘要： A retractor for percutaneous surgery in a patient which includes an elongate retractor tube composed of circumferentially arranged elongate independent tube segments with proximal ends of the tube segments respectively hinged to a unitary collar whereby the distal ends of the tube segments may be outwardly expanded in umbrella fashion by outwardly pivoting the segments about their respective hinges for thereby retracting surrounding tissue. The distal end of the retractor tube is provided with a tapered distal end suitably dimensioned for insertion into a stab incision. An internally open expansion collet is coaxially received in the collar for adjustable coaxial advancement downwardly into the collar toward the retractor tube segments and fulcrum tabs protrude inwardly and upwardly towards the expansion collet from each tube segment adjacent a respective hinge. The fulcrum tabs are sized for engaging a bottom end of the collet for thereby progressively pivoting the segments outward about their hinges as the collet advances downwardly into the collar.
