Abstract: Disclosed are an optical fiber connector assembly, an optical fiber connector plug, and an adapter assembly, comprising an optical fiber connector plug, an optical fiber connector adapter, and an adapter base plate. A plug information storage chip and an indicator light-guiding pillar are arranged in parallel on a bottom side of the optical fiber connector plug. Each pin of the plug information storage chip is electrically connected to conductive slide-rails. Metal elastic pins and an indicator light accommodation portion are arranged in parallel on a bottom side of a plug opening of the optical fiber connector adapter. Pin contacts and an indicator light are arranged in parallel on the adapter base plate. When the adapter is mounted on the adapter base plate, the indicator light is accommodated in the indicator light accommodation portion and the metal elastic pins are electrically connected to the pin contacts.

Abstract: Disclosed are a powering off and rebooting method, apparatus and system. Wherein, the method includes: an office-end device monitoring a user-end access device; and when the office-end device monitors that the user-end access device is halted, sending a reboot command to the user-end access device; wherein the reboot command is used for indicating a power supply module in the user-end access device to perform a powering off and rebooting operation on the user-end access device. The abovementioned solution solves the problem in the related art that technical personnel have to go to the site to reboot a device if the software reset is invalid when the device is halted, so that research and development technical personnel can timely and easily power off and reboot the device without going to the site, thus treating a failure timely and reducing maintenance costs, and improving the operability and maintenance efficiency of maintenance personnel.

Abstract: A guiding apparatus for x-ray-free screw placement by a spinal posterior approach, comprising an interspinous spacer, a slide scale (1), and an angle-changing rod. The apparatus is simple to operate, easy to grasp, and well accepted by physicians. A reliable effect is provided in screw placement. Significantly reduced X-ray exposure is allowed for patients and medical staff. In a small-incision minimally invasive screw placement operation, even without exposing the spinal ligament, a small spike-like protrusion of a base (2) of the interspinous spacer can ensure accurate interspinous positioning across the skin. This is applicable for both minimally invasive and incision surgeries and has a wide range of uses.

Abstract: An exposure apparatus for a paraspinal muscle clearance approach with a posterior spinal small incision includes a spinous process side vertebral plate retractor and a cooperating vertebral arch outer side retractor is provided. The apparatus can be used to separate a clearance between a multifidus muscle and a longissimus muscle under direct view, easily and atraumatically reach a screw fixation position on a vertebral arch pedicle, expose a facet joint, bluntly separate the multifidus muscle from the vertebral arch, accurately place the retractors, and thereafter locally form a surgical operation tunnel space that externally extends 10 degrees to 15 degrees. A design of angles and structures of retractors effectively protects local soft tissues and prevents a tissue damage while executing traction on local muscles and ensuring an adequate surgical space.

Abstract: An exposure apparatus for posterior spinal minimally invasive screw placement surgery includes a transverse process refractor and a facet joint retractor, is provided. The apparatus separates a gap between a multifidus muscle and a longissimus muscle, easily and atraumatically reach a screw placement position on a pedicle, accurately place the retractors, and thereafter locally form a screw placement tunnel space that externally extends 10 to 15 degrees. During a screw placement operation, the distal end of the transverse process refractor can straddle above the transverse process and is antagonistically tractive with the facet joint retractor so as to leave a sufficient space for the screw placement operation and to prompt a needle inlet point and direction for placing a pedicle screw. The distal end of the refractor employs a design of a recessed crescent type, protects local soft tissues during traction, and prevents the tissues from damage.
