Abstract

The invention relates to a production method for a guide template. The production method comprises the following steps of: at first, importing CT (computed tomography) serial sectional image data into three-dimensional rebuilding software such as Mimics 10.01 for three-dimensional model rebuilding by CT scanning; then, designing a guide plate with vertebral pedicle positioning guide holes in the two sides of a single vertebral body on a digital lumbar vertebra anatomical model subjected to three-dimensional rebuilding; and finally, producing the template by a laser irradiation layer-by-layer curing and forming technology. The guide template produced by the method can be satisfactorily and closely combined with the vertebral body, can be used for accurately positioning and orienting vertebral pedicle, and guarantees the correct implantation position and direction of vertebral pedicle screws.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a method for preparing a guide template using computer-aided design technology, reverse engineering technology and rapid prototyping technology, and the guide template is used to assist the implantation of pedicle screws. Background technique [0002] With the updating and development of technology, pedicle internal fixation technology is gradually applied in the surgical treatment of spinal diseases such as degenerative spinal lesions, slippage, spinal stenosis, vertebral fractures, deformities, bone metastases, and spinal instability. It has played an indelible role in the development and progress of spine surgery. [0003] Biomechanical experiments have proved that the stability of the screw-rod system and the ideal clinical efficacy can only be guaranteed if the screw is accurately placed along the only anatomical long-axis channel of the pedicle and reaches the ideal depth [LA...
