Positioning system for minimally invasive spine surgery and application of same in minimally invasive spine surgery positioning

Abstract

The invention discloses a positioning system for a minimally invasive spine surgery and application of the same. The system comprises a base, a z-axis guide rod disposed on the base, a z-axis scale, a first graduated scale and a first vernier extending in the x-axis direction, a second graduated scale and a second vernier extending in the y-axis direction, a first angle scale connected to the second vernier, a first rotation part, a second angle scale, a second rotation part, an indication pointer and a needle clamping device used to hold a puncture needle, wherein the first angle scale extends in the x-z plane and has scales; the first rotation part is connected to the second vernier and can be rotated along a center axis parallel to the y-axis; the second angle scale extends in the plane perpendicular to the first angle scale and has scales; the second rotation part is rotated along a second rotation axis perpendicular to the second angle scale; and the indication pointer can be rotated with the second rotation part and is used to mark a rotation angle. The positioning system for the minimally invasive spine surgery has the advantages that damage of important tissues caused by puncture position inaccuracy in the minimally invasive surgery can be avoided; risks in a patient's surgery can be reduced; and thus, positioning of the minimally invasive spine surgery becomes more accurate.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgery, in particular to a spinal minimally invasive positioning system and its application in spinal minimally invasive positioning. Background technique [0002] Minimally invasive surgery is the application of advanced tools (such as computers, special puncture guide needles, special retractors and imaging equipment) to complete traditional operations through special surgical approaches, so as to achieve the least tissue damage to patients, the lightest The psychological impact, the fastest recovery and the best surgical results. [0003] Minimally invasive spinal surgery is a surgical method for the treatment of various spinal diseases (such as osteoporotic compression fractures, spinal traumatic fractures, lumbar disc herniation, lumbar spinal stenosis, etc.) that has emerged in recent years. Small size, short operation time, good postoperative effect and many other advantages. ...

Problems solved by technology

However, in this operation, the surgical instrument must be punctured directly through the skin and accurately reach the "safe triangle working area", so that the resection of the herniated lumbar intervertebral disc can be safely and smoothly performed under the endoscope
