Abstract

The invention discloses a spine stabilizing device. The spine stabilizing device comprises vertebra joint fixing devices (1) and a rod body (2), each vertebra joint fixing device (1) comprises a spine body (3), a main bolt (4) and a spherical head (5), wherein each spine body (3) is internally provided with a cavity and a screw hole (6), the screw hole (6) is communicated with the cavity, the screw hole is located above the cavity body, the screw hole (6) is in threaded connection with a pressing head (7), the cavity is internally provided with a fixed base (8), the fixed base (8) is internally provided with a spherical cavity, the spherical cavity is internally provided with a spherical head (5) which is matched with the spherical cavity, the spherical head (5) is in threaded connection with the main bolt (4), the main bolt (4) extends to the outer part of the spine body (3), and the rod body (2) abuts against the space between the head of the main bolt (4) and the bottom of the pressing head (7). The spine stabilizing device has the advantages that the structure is compact, the recovery phase is short, the connection is firm, the screwing force is saved, and the spine stabilizing device is applicable to patients of different ages.

Description

technical field [0001] The invention relates to the technical field of spinal solid support, in particular to a spinal stabilization device. Background technique [0002] At present, when the human spine is deformed due to fractures, lesions and other reasons, the commonly used quality method is to install a spinal internal fixator on the deformed part of the spine through surgery to correct and title the spine, help the spine recover function or delay the deterioration of the disease. The spine is an indispensable part of supporting the human body. The spine is composed of multiple vertebral joints connected in series. If two adjacent vertebral joints are broken or misplaced, the human body will not be able to walk. Therefore, it is necessary to connect multiple vertebral joints into one body. The spinal joints are connected as a whole by using the solid state system of the spine. The system consists of a rod body and a plurality of screws threaded on the rod body. The scre...
