The present invention relates to a device for treating vertebral deformities, consisting of two rods (1 ), suitably curved to correct the deformity, which are attached by means of pedicle screws (2) at the level of the thoracic and lumbar vertebrae, comprising a plurality of segments (6, 3, 8), aligned and joined by a bushing (4), equipped with a transversal pin (7) that delimits the separation movement of the respective consecutive segments coupled thereto and, between two consecutive bushings (4), a bushing (5) sliding on the intermediate segment (3) on which it is mounted. A tightener (10) connects the first upper segment (6) forming each rod (1 ) to the last lower segment (8), passing through all the intermediate segments (3) and is provided with a tightening means that keeps all the segments aligned to form a rigid rod, and a loosening means that allows the separation between the segments and the displacement of the bushings (5) along the segment (3) on which they are mounted, so that the rod (1 ) can be lengthened to allow the patient's growth and the anteroposterior movement of the spine.

An assembly for correcting spinal deformities may include at least lateral rods extending across adjacent vertebrae to be retained at either end by pedicle screws. A cross-coupler may be coupled to each lateral rod, and a longitudinal rod may run along the spine and be coupled to the lateral rods by the cross-couplers. The assembly may be used to correct spinal deformities by manipulating the pedicle screws or cross-couplers to rotate about the lateral rods or the longitudinal rod.

The application discloses a kind of percutaneous minimally invasive lumbar pedicle screw fixation system and matching instruments, comprising: shell;Telescopic rod, telescopic rod fixedly connected shell side;Handle, telescopic rod is fixedly connected with handle at one end away from shell;Distraction mechanism, located in the shell interior;Strip-shaped plate, located in the shell exterior, and is connected with distraction mechanism;Detection positioning device, located in the two sides of strip-shaped plate;Distraction mechanism contains first recess, motor push rod, trapezoidal slider, special-shaped slider, second recess and first motor, the gap of the skeleton needing to be treated is opened by distraction mechanism, the operation space of medical staff is increased, and medical staff can better observe and handle pathological tissue, wherein the angle and interval of distraction mechanism can be flexibly adjusted, and the operation of subsequent operation is facilitated by maintaining the stability of vertebral body, wherein the detection lamp can display the situation of operation in real time, help medical staff to quickly locate, operate and correct, improve the efficiency of operation.

The invention discloses a spinal surgery pedicle screw fixing device which comprises a mounting screw seat, the lower end of the mounting screw seat is fixedly connected with a pedicle screw body, and a connecting titanium rod is arranged in a through groove in a penetrating mode; the first mounting wheel is arranged in the mounting nail seat, and a pressing block is arranged above the first mounting wheel; the second transmission wheel is fixedly connected to the lower end of the transmission rod; and the connecting groove is formed in the left end face of the mounting nail seat, and the interior of the connecting groove is connected with a limiting assembly. According to the vertebral pedicle screw fixing device for the spine surgery department, the connecting titanium rod can be bidirectionally positioned, the connecting high position can be adjusted when the connecting titanium rod is connected, meanwhile, the locking effect on the connecting titanium rod is improved, the connecting titanium rod is conveniently prevented from loosening and slipping, and the service life of the connecting titanium rod is prolonged. The problems that according to most existing pedicle screw fixing devices, a connecting rod is limited and fixed in the mode that a single screw plug is pressed downwards, the installation depth of a screw needs to be adjusted, and operation is troublesome are solved.
