Abstract

The invention discloses a transpedicular channel vertebral body excision device, which comprises a drill bit, a transmission connecting part and a handle part which are connected in sequence, and thedrill bit can freely rotate and bend relative to the transmission connecting part; a first transmission assembly and a second transmission assembly are arranged in the transmission connecting part, the first transmission assembly is connected with drill bit and drives the drill bit to rotate on the transmission connecting part, and the second transmission assembly is connected with the drill bit and drives the drill bit to adjust the bending angle between the drill bit and the transmission connecting part. The transpedicular channel vertebral body excision device can excise most of the diseased vertebral body through the transpedicular channel in eggshell mode, and refill bone cement for vertebroplasty to reconstruct the stability of the spine, which has small trauma , low risk and low cost, and huge social benefits.

Description

technical field [0001] The invention relates to surgical medical instruments, in particular to a vertebral body excisor through a pedicle channel. Background technique [0002] When vertebral metastases need to be treated surgically, the existing traditional method is to resection most or all of the diseased vertebra through anterior or posterior spinal approach, or anterior-posterior combined approach, and then perform bone grafting and plate fixation to reconstruct spinal stability. Sex, surgical trauma, high risk, high cost. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned deficiencies of the prior art, the present invention provides a vertebral body excision device through the pedicle channel, which can remove most of the diseased vertebrae through the pedicle channel, eggshell type, and re-perfuse bone cement for vertebroplasty , Reconstructing the stability of the spine, with less trauma, less risk, less cost, and huge social benefits. [000...
