Abstract

The invention discloses a navigation template capable of being used for positioning vertebral pedicle. A manufacture method of the navigation template comprises the following steps of: firstly, acquiring original data and establishing a three-dimensional vertebra model on a computer; secondly, carrying out three-dimensional analysis on a vertebral pedicle needle-entering channel, extracting an outline of the rear part of a vertebral plate, establishing a virtual reverse template coincide to the outline at the rear part of the vertebral plate in a system; thirdly, fitting the virtual reverse template with the vertebral pedicle needle-entering channel, establishing a virtual needle-entering template; and fourthly, manufacturing the needle-entering template by using a quick forming technology, wherein the needle-entering template is a reverse navigation template coincide to the outline of the rear part of the vertebral plate. The invention organically integrates a digital technology, reverse engineering and the quick forming technology, thereby achieving the purpose of rapidly, cheaply and efficiently accurately positioning the vertebral pedicle.

Description

technical field

[0001] The invention relates to a manufacturing method of a navigation template that can be used for pedicle positioning, and a navigation template that can be used for pedicle positioning made by the method. Background technique

[0002] In orthopedic operations such as spinal trauma reduction and deformity correction, it is generally believed that internal fixation with pedicle screws is the most stable spinal fixation method. However, since the diameter of the pedicles of the thoracic and cervical spine gradually decreases from the lumbar spine up, the difficulty and risk of pedicle screw fixation gradually increase, and mistakes may cause great damage. The pedicle technology of the thoracic and cervical spine Difficult to popularize clinically.

[0003] Therefore, people began to look for a spinal navigation system capable of accurate positioning, so as to accurately locate the pedicle and ensure the smooth progress of the operation. The use of computer...
