Abstract

A navigation template for spine pedicle screw placement includes a navigation template body and two guide columns arranged on the navigation template body, the inner side surface of the navigation template body has a three-dimensional curved surface that coincides with a use position, and the middle part of the three-dimensional curved surface has a curved surface feature that coincides with a spinous process bone marker of the use position; the two guide columns are arranged on both sides of the navigation template body, and a through hole is arranged in each guide column. The navigation template for the spine pedicle screw placement provided by the invention makes full use of the structural characteristics of a vertebral pedicle where a screw is placed and the spinous process marker, a 3D printing technology is also used to prepare the navigation template which fits with a surgical part and can be quickly placed in the surgical part, so that the accurate and fast screw placement canbe realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a navigation template for spinal pedicle screw placement. Background technique [0002] When diseases such as scoliosis, deformity, and spondylolisthesis reduction occur in the human spine, surgical treatment using spinal rod fixation is a common and effective means. Spinal screw and rod fixation, that is, spinal pedicle screw fixation, requires accurate placement of screw holes and screws at the appropriate position of the spinal pedicle. The existing insertion methods are all manual operations based on the experience of doctors. Insertion, such an operation method is likely to cause deviation of the insertion hole position due to human factors, deviation of the insertion position of the pedicle screw, and the phenomenon that the screw cannot be inserted if the deformity is serious, which will affect the treatment time and treatment effect. The main reason is that the a...
