Abstract

The present invention relates to internal lumber vertebra fixture and is especially one front locking fixture plate with screws for lumber vertebra. The front locking fixture plate includes fixing plate and fixing screw, and features the fixing plate in the kurtorachic shape and with 2x3 screw holes with fixing screws, and the screws with arc cut in the head and locked with two other screws separately. The present invention has simple structure, high fixing strength, high safety and small operation wound.

Description

1. Technical field [0001] The invention belongs to a medical internal plant device, and relates to an internal fixation device of a lumbar vertebral body, in particular to a self-locking fixation nail plate in front of a lumbar vertebral body. 2. Background technology [0002] Spinal internal fixation is a basic and important technique for treating spinal injuries, especially in the treatment of lumbar injuries. Among the internal fixation devices currently used for the lumbar spine, there are mainly posterior (or rear) fixation devices for the lumbar spine, lateral fixation devices for the lumbar vertebral body, and frontal fixation devices for the lumbar vertebral body. [0003] Various vertebral screw solid devices are commonly used in the lumbar posterior (or rear) fixation device at present, and the lumbar vertebral body is fixed through the connection between the screw and the rod. This type of fixation device has the following defects: (1) the installation of the fix...
