Problems solved by technology

[0003] When the existing spinal non-fusion internal fixator is in use, the operator fixes the root nail on the corresponding spine, and then passes the root nails fixed on the spine through the fixing rod for fixation, thereby achieving internal fixation. As a result, in the connection between the fixed rod and the end frame of the root nail, the compression nut is used for compression, which leads to poor fixing effect on the fixed rod, making it prone to the problem of slipping and dislocation of the fixed rod

Abstract

The invention discloses a spine non-fusion internal fixator which comprises a connecting rod, the two ends of the connecting rod are sleeved with sliding sleeves, a fixing rod penetrates through the sliding sleeves, the outer wall of the fixing rod is sleeved with an end frame, a side frame is embedded in the side portion of one end of the end frame, and an end plate is arranged in the side frame. A tooth block is fixed to one end of the end plate, tooth grooves are formed in one side of the outer wall of the fixing rod in a linear array mode, one end of the tooth block is arranged in the tooth grooves, and a pull rod is fixed to the center of the surface of the other end of the end plate. The end plate, the side frame and the tooth grooves are designed, the side frame is installed on the end frame, and the end plate provided with the tooth block is located in the side frame, so that the fixing rod and the end frame are clamped and fixed in the tooth grooves through the tooth block, it is guaranteed that the fixing and limiting are more stable, displacement is not likely to happen, and the tooth block can be pulled and adjusted conveniently through the designed pull rod.

Description

Technical field [0001] The present invention belongs to the technical field of medical devices, and in particular to a spine non-fusion internal fixator. Background technique [0002] Surgery for treating spinal bending, especially the spine of adolescents and children, when the internal fixation, the internal fixation of the internal fixation, to maintain the effect of the surgery, increase the spinal bone fusion rate, the spine non-fusion internal fixator is A non-fusion fixing assembly for spinal deformation treatment, connecting its spine through a holder to correct restrictions, making it recovering. [0003] When the existing spine is in use, the operator fixes its root nail on the corresponding spine, and then fixes the root nu fixed on the spine together by the fixed bar to reach the internal fixation. Effect, in the connection of the terminal frame of the fixing rod and the root nail, use the pressure-solid nut to cause pressure, resulting in poor fixation effect on the ...
