A polyaxial ball and socket joint that can be locked into a fixed position. The fastening system consists of the polyaxial ball and socket joint used in conjunction with a bone screw having threads on one end for use in anchoring to the spine and a spherical connector on the other end operating as a pivot point about which a connecting assembly moves in a polyaxial fashion. A substantially U-shaped connecting assembly has a lower receptacle that operates as a socket for housing an upper retainer ring and a lower split retaining ring. The socket is receptive to the spherical connector which is inserted through the lower split retainer ring causing a momentary displacement thereof which allows for the positioning of the spherical connector between the upper and lower retainer rings.

A substantially U-shaped connecting assembly has a lower receptacle that operates as a socket for housing an upper retainer ring and a lower split retaining ring. The socket is receptive to the spherical connector which is inserted through the lower split retainer ring causing a momentary displacement thereof which allows for the positioning of the spherical connector between the upper and lower retainer rings. A resilient component positioned between the upper retainer ring and the connecting assembly permits relative predetermined placement and retention of the spherical connector relative to the connector assembly due to the force generated by the resilient component and frictional engagement between the surfaces of spherical connector, the upper and lower retainer rings and the connector assembly. The polyaxial ball and socket can be locked into a fixed position.

A thread-thru polyaxial pedicle screw fastening system. The fastening system consists of an anchoring bone screw having threads on one end for use in anchoring to the screw to the spine and a spherical connector on the other end operating as a pivot point about which a U-shaped connecting assembly moves in a polyaxial fashion. The U-shaped connecting assembly, for receipt of a spinal connecting rod, has a biased retainer ring for maintaining a positive tension between the connecting assembly and the anchored screw. The system allows for an improved manufacturing step wherein the threaded shank of a bone screws can be passed through a lower portion of the connecting assembly allowing a variety of bone screw sizes to be used with a common sized connector. A resilient component positioned between the upper retainer ring and the connecting assembly permits relative predetermined placement and retention of the spherical connector relative to the connector assembly due to the force generated by the resilient component and frictional engagement between the surfaces of spherical connector, the retainer ring and the connector assembly. The polyaxial ball and socket can be locked into a fixed position.

A fastening system for bone screws used in spinal fixation systems for reshaping the spine of a patient. The bone screw has threads on one end for anchoring in the spine. The other end has a spherical head with a multi sided recess formed therein for engagement with an appropriate driving tool. The system includes a stabilizing rod, a saddle member, a cap member and a set screw with at least one bone screw having a outer diameter that exceeds the diameter of a cavity formed in the saddle, wherein placement of the bone screw is made possible by matching the threads of the set screw to the threads of the bone screw. The head of the bone screw providing proper positioning of the stabilization rod within the patient.

An imaging lens includes a first lens having positive refractive power; a second lens having negative refractive power; a third lens; a fourth lens having negative refractive power; a fifth lens having positive refractive power; and a sixth lens, arranged in this order from an object side to an image plane side. The first lens is formed so that a surface thereof on the object side has a positive curvature radius. The second lens is formed so that a surface thereof on the image plane side has a positive curvature radius. The fifth lens is formed so that a surface thereof on the object side and a surface thereof on the image plane side have negative curvature radii. Each of the third lens, the fourth lens, the fifth lens, and the sixth lens has refractive power weaker than that of each of the first lens and the second lens.

An imaging lens includes a first lens having positive refractive power; a second lens having negative refractive power; a third lens having positive refractive power; and a fourth and a fifth lens having negative refractive power. The first lens is formed so that a curvature radius of an object-side surface is positive and the second lens is formed so that a curvature radius of an object-side surface and a curvature radius of an image plane-side surface are positive. The third lens is formed so that a curvature radius of an object-side surface is positive, and the fifth lens is formed so that a curvature radius of an object-side surface and a curvature radius of an image plane-side surface are both positive. An Abbe's number from the first and the third to the fifth lens is greater than 45, and an Abbe's number of the second lens is less than 35.

A zoom lens system capable of correcting a secondary spectrum is disclosed. The zoom lens system includes a first lens unit with a positive optical power, a second lens unit with a negative optical power, an aperture stop, and a rear lens component including at least one lens unit in an order from an object side to an image side. In the zoom lens system, during zooming from a wide angle end to a telephoto end, an interval between the first lens unit and the second lens unit increases, and an interval between the second lens unit and the aperture stop decreases. Then, a material satisfying the following conditions:νd1n<35θgF1n <−0.0027νd1n+0.680is used for the negative lens in the first lens unit. Herein, νd1n represents an Abbe number, and θgF1n represents a partial dispersion ratio.
