A bone fixation device includes: a bone plate having a plurality of through holes; and one or a plurality of bone screws; wherein the bone plate is provided with a slide track on a surface thereof, and the bone plate is further provided with one or a plurality of sliding covers slidablely connected to the slide track and capable of covering the through holes. The bone screws has a threaded body, a head and a neck therebetween, wherein a thread of the threaded body close to the neck has an angle slightly inclined towards to the threaded body.

Bone fixation device

A device is designed to anchor a tissue to a bone. The device comprises a contractible implant, one or more sutures attached to the implant, and a pasty medicine capable of solidification. The implant is made of a flexible wall and provided with a holding portion and an injection port. The flexible wall is provided with a plurality of pores, each having a diameter smaller than 0.1 millimeter. The pasty medicine is injected into the holding portion of the implant upon completion of insertion of the contracted implant into the bone, thereby resulting in expansion of the contracted implant. The implant is thus securely lodged in the bone upon solidification of the pasty medicine to facilitate the anchoring of the tissue to the bone by suturing.

A plug-type spinal retrieving device includes a retrieval rod; a fastening screw assembly including a fastening screw and a C-shaped ring having a convex outer surface; a plug; and a fixation seat having a receiving hole in which the retrieval rod is slidably received, a fastening hole having a concave wall in which the C-shaped ring is rotatably received, and an interconnecting hole through which the receiving hole communicates with the fastening hole. The C-shaped ring is mounted on the fastening screw, so that the fastening screw is grasped by the C-shaped ring, when the C-shaped ring is received in the fastening hole of the fixation seat. The C-shaped ring and the retrieval rod are immobilized in the fastening hole and the receiving hole of the fixation seat by inserting the plug into the interconnecting hole.

The monitoring system of the present invention has Group ID (GID) and Sort ID functions, and automatically replies according to the order of the Sort ID after identifying the Group ID and confirming that it is necessary to reply. The present invention also discloses a radio medical monitoring method.

Radio medical monitoring method and radio medical monitoring system

A vertebral fixation device. The device includes a fixation seat, a fixation block, and a fastening bolt. The fixation seat is provided with a receiving slot for receiving a vertebral fixation rod. The fixation block is engaged with the fixation seat such that the vertebral fixation rod is pressed by the fixation block, and two retaining edges of the fixation block are retained in two retaining recesses of the fixation seat. The fastening bolt is engaged with a threaded through hole of the fixation block such that one end of the fastening bolt presses against the vertebral fixation rod.

A transverse connector clip for connecting cylindrical rods to each other in a spinal fixation system, comprising a clip body having a two sides. The first side of the clip body has a longitudinal axis and a pair of mirror image hemi-cylindrical shells. These hemi-cylindrical shells have an inner diameter that is slightly smaller than the outer diameter of a cylindrical rod. The clip body is shaped so as to allow the hemi-cylindrical shells to spread around the cylindrical rod when the cylindrical rod is inserted between said shells and to securely clamp on the cylindrical rod at a 90&deg; angle relative to the clip body The second side of the clip body can comprise one of several embodiments; a short laterally extending hemi-cylinder rod, a laterally extending hemi-cylinder rod with a plurality of vertical teeth, a second pair of mirror image hemi-cylindrical shells, a laterally extending rod tapering from a proximal cylindrical shape to a distal hemi-cylinder shape, or a body portion and a locking mechanism configured to receive and lock a hemi-cylindrical or cylindrical rod.

Transverse rod connector clip

A spinal fixation system includes a first clip body having a pair of opposed spaced apart arcuate rod engaging hooks depending from a first side thereof for engaging a first elongated spinal rod, and a transverse connector extending laterally from a second side thereof; a second clip body having a pair of opposed spaced apart arcuate rod engaging hooks depending from a first side thereof for engaging a second elongated spinal rod, and a transverse connector extending laterally from a second side thereof; and a fastener for securing the transverse connector of the first elongated clip body and the transverse connector of the second elongated clip body to one another.

A spinal fixation and retrieval device comprises a retrieval main body, two side pieces, and a fastening device for fastening substantially symmetrically the two side pieces with two sides of the retrieval main body. The two side pieces are substantially smaller in thickness than the retrieval main body.

Spinal fixation and retrieval device having side pieces

A spine fixing device includes a main hooked seat, two extension hooks, and two fastening members. The main hooked seat is provided with a main hooked portion, two extension arms, and two fastening rods for fastening two fixation rods of the prior art. The extension hook is provided at one end with a curved portion, and at other end with an adjustment portion which is fastened with one of the two extension arms of the main hooked seat by one of the two fastening members. The device is retained in the back of one spinal segment such that the main hooked portion is inserted into a portion of the spinal canal of the spinal segment, and that the extension arms embrace the spinal projection of the spinal segment, and further that the curved portions of the extension hooks catch two different portions of the spinal canal of the spinal segment from the opposite direction.

Three-hooked device for fixing spinal column

The present invention is directed to one piece connector for connecting angularly misaligned implanted pedicle screws to transverse spinal rods in spinal fixation systems. The body portion includes a bore having an inside diameter and a longitudinal axis, with the longitudinal axis of the bore being positioned perpendicular to the longitudinal axis of the leg portion. The leg portion includes a slot placed through a section of the leg portion, along the transverse axis of the leg portion and parallel to the longitudinal axis of the leg portion. The slot intersects the bore of the body portion perpendicular to the longitudinal axis of the bore. The slot allows the one piece connector to be securely clamped around a longitudinal spinal rod when a pedicle screw is implanted at variable distances from the longitudinal spinal rod. The one piece connector allows for angular misalignment of an implanted pedicle screw in relation to a longitudinal spinal rod and the one piece connector, and for the attachment of the one piece connector to both the longitudinal spinal rod and to the implanted pedicle screw with a single locking mechanism when the one piece connector is used in a spinal fixation system.

A method is designed to control the working time, setting time and the semi-solidification time of a gypsum composition in a bone restoration operation. The method involves a preparation of the gypsum composition by mixing an orthopedic gypsum and an aqueous solution in a weight ratio to form a semisolid substance which is to be injected into a patient under treatment. The aqueous solution contains serum, blood plasma, or whole blood, which is preferably taken from the patient under treatment.
