摘要:
A medical instrument apparatus and method is provided for positioning and securing a spinal rod to a coupling device anchored to a vertebra. A reducer assembly shifts the spinal rod into place within the coupling device and a cap inserter assembly shifts a cap member into locking engagement with the coupling device to secure the spinal rod therein.

A manufacturing apparatus, for moving sliders for opening and closing mating zipper elements along the mating zipper elements, includes a roller and a projection. The roller rotates about an axis substantially perpendicular with a path of a film including the mating zipper elements and contacts the film as the film moves in the film path at a speed equal to the speed of rotation of the roller. The projection rotates about an axis at a speed different than the rotational speed of the roller, with the projection rotating into proximity to the moving film along predetermined lengths of the film so as to be contactable with sliders mounted thereon. The projection comes into contact with sliders positioned along the mating zipper elements of the predetermined lengths of film and pushes those sliders along the mating zipper elements to respective registered positions.

A pouch production apparatus includes a pouch forming apparatus operable to form pouches from an elongate web of material and zipper tape and an extrusion apparatus responsive to operation of the pouch forming apparatus and operable to extrude zipper tape. A pneumatic transport apparatus is operable to transport the zipper tape from the extrusion apparatus to the pouch forming apparatus during operation of the pouch forming apparatus. A method of producing a pouch using such apparatus is also disclosed.

Instruments are provided herein for reducing the lateral distance between a spinal rod anchored to a spine and a coupling device. The instruments permit a rod to be shifted into a coupling device that is not in alignment with other coupling devices secured to the rod because of rotational deformities causing one or more vertebrae to be shifted with respect to at least one other vertebra.

A spinal fixation system is provided that includes a coupling member and a locking device that is operable to fix an elongate member in the coupling member. There is also provided insertion instruments configured to install and remove various components of the spinal fixation system. In one form, the coupling member includes opposing side wall portions having a resilient portion on at least one of the side wall portions that cooperates with the locking device for being inserted into the coupling member via resilient flexing of the resilient portion. The coupling member and locking device also preferably include cooperating structure therebetween to define a plurality of distinct positions of the locking device in the coupling member.

A method and system for performing image mark recognition for a document is disclosed. A document is scanned into a digital image. Reference image marks are sensed from the digital image. The reference image marks may include trigger row marks and/or corner/crop marks. Coordinates denoting the location of cells within the digital image are determined based on the locations of the reference image marks. Response marks are evaluated for darkness, opacity, and/or grayness on a pixel-by-pixel basis. The response marks are each assigned a percentage value based on the ratio between a total color value for a cell and a maximum color value for a cell.

A closure assembly includes a slider for opening and/or closing an elongate closure mechanism including a pair of opposing closure members. The slider includes a first separator finger and a second separator finger, each of which is articulably connected to a hinge member. The first and second separator fingers extend between the closure members and may be articulated between a closing position, in which the separator fingers are adjacent each other, and an opening position, in which the separator fingers are laterally spaced from each other. In the opening position, the separator fingers urge the members apart. Closing bars and retention members may also be included to facilitate re-closing the closure members and retaining the slider in an operative position thereon.

A lithographic apparatus includes a projection system, which includes a plurality of cubic crystalline optical elements that each impart retardance to a beam of radiation. The optical elements are aligned along an optical axis of the projection system and include two adjacent crystalline optical elements having a common crystalline lattice direction oriented along the optical axis. A first of the two adjacent elements is rotated about the optical axis with respect to a second of the adjacent elements with a predetermined rotation angle. The crystalline optical elements are selected and positioned along the optical axis and the rotation angle is selected such that, for each of two substantially perpendicular polarization states of the beam of radiation having a radiation wavelength of about 193 nm, the patterned beam of radiation has less than about 0.012 waves RMS of wavefront aberration across an exit pupil of the projection system.
