Embodiment 1

[0021] For patients with spinal fractures, spinal retirement diseases, spinal deformities, or other spinal fixation operations, when the spinal fixation operation is performed, after the fixation screws and the main rod are installed, in order to further strengthen the fixation strength, if it is necessary to install the main rod of the auxiliary rod The position is sufficient and the distance is accurate. Select an auxiliary rod (101) with a suitable length and two ends directly connected to the connector (201), install the main rod into the main rod groove (202) on one side of the connector, and the position is satisfactory. Finally, screw in the fastening screw (204) in the screw hole (203) above, and after the fixation is completed, other operations of the operation are completed.

Embodiment 2

[0023] For patients with spinal fractures, spinal retirement diseases, spinal deformities, or other spinal fixation operations, when the spinal fixation operation is performed, after the fixation screws and the main rod are installed, in order to further strengthen the fixation strength, if it is necessary to install the main rod of the auxiliary rod The position of the main rod between the two fixing screws on one side is sufficient, and the distance between the two fixing screws on the other side is too small, but the total length distance is exact. Choose a suitable length for direct fixed connection with connectors (201) at both ends. Auxiliary rod (101), but one of the connectors installed on the side where the distance between the two fixing screws is too small needs to choose a connector designed with two main rod grooves separated by a certain distance, and install the main rods one by one. In the main rod groove (202), after the position is satisfactory, screw in the f...

Embodiment 3

[0025] For patients with spinal fractures, spinal retirement diseases, spinal deformities, or other patients who need spinal fixation surgery, after the fixation screws and main rod are installed, in order to further strengthen the fixation strength, if the two fixation screws on both sides The distance is too small, but the total length is exact. Choose an auxiliary rod (101) with a suitable length that is directly connected to the connector (201) at both ends. At this time, both sides need to be fixedly connected. For the connector of the main rod groove, install the main rods one by one in the main rod groove (202). After the position is satisfactory, screw the fastening screw (204) into the upper screw hole (203). After the fixation is completed, the operation is completed other operations.

Abstract

The invention relates to an auxiliary spine internal fixation device capable of reinforcing the intensity of an internal fixation system in the operation of the spine internal fixation, and a use method of the auxiliary spine internal fixation device. The auxiliary spine internal fixation device is composed of an auxiliary rod, a plurality of connectors and a plurality of fastening screws, wherein the auxiliary rod and the connectors can be directly fixedly connected, or can be connected through auxiliary rod grooves designed on the connectors, the other sides of the connectors are provided with main rod grooves used for connection with a main rod, in design, one independent main rod groove can be adopted for connecting the main rod between two fastening screws, two main rod grooves spaced at a certain distance also can be adopted, Y-shaped design is adopted, and the main rod grooves adopting the design can be used for connection with the main rod on the two sides of the fastening screws. The auxiliary spine internal fixation device is made of titanium alloy, magnesium alloy or a stainless steel material having good biocompatibility. With the adoption of the device, the intensity of the internal fixation system can be greatly improved, and thus the occurrence of complications such as rod breakage and angle loss can be reduced.

Description

technical field [0001] The invention relates to a spinal auxiliary internal fixation device that can strengthen the strength of the internal fixation system when used for spinal internal fixation and its use method. The invention can greatly improve the strength of the internal fixation system, thereby reducing the risk of complications such as broken rods and angle loss. occur. Background technique [0002] Spinal fractures, spinal degenerative diseases, scoliosis and other spinal deformities, once the surgical indications are reached, various surgical treatments are required. The reconstructed spine requires internal fixation to provide good stability. The current internal fixation includes screw-rod systems based on pedicle screws and connecting rods, as well as various cortical bone screw systems, hook rod systems, laminar strap systems, etc., but these systems all require a connecting rod to fix the connection. . Clinically, for many severe fractures, spinal deformit...
