Embodiment Construction

[0021] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that although the preferred spondylosacral coefficient of the present invention and the data of the lumbar intervertebral space corresponding to the vertex of the equilateral triangle come from the Asian population, But the present invention is not limited to the scope of the specific implementation. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious. Inventions and creations utilizing the concept of the present invention are all included in the protection list.

[0022] refer to figure 1 , figure 1 A flow chart of an embodiment of a spinal lumbar space positioning method is shown; as figure 1 As shown, the method 100 includes steps 101 to 105 .

Abstract

The invention discloses a positioning method for a spine lumbar vertebra gap. The method comprises the steps that the spine length and the sacrum width of a patient are acquired; a spine-sacrum coefficient of the patient is computed, wherein the spine-sacrum coefficient=spine length / sacrum width; the patient's sacrum width is used as a bottom edge to establish an equilateral triangle, wherein the vertex of the equilateral triangle is located on the waist-section spine; according to data relations between the patient's spine-sacrum coefficient and the lumbar vertebra gap corresponding to the vertex of the equilateral triangle, the position of the centrum gap or centrum crest corresponding to the vertex of the equilateral triangle could be obtained; and the position of an adjacent lumbar vertebra gap on the spine could be obtained through moving from the position corresponding to the vertex of the equilateral triangle along the spine direction.

Description

technical field [0001] The invention relates to the technical field of anesthesia, in particular to a spinal and lumbar intervertebral space positioning method. Background technique [0002] Spinal anesthesia is one of the main clinical anesthesia methods, and correct positioning of the lumbar intervertebral space is a prerequisite for ensuring the anesthesia effect and reducing nerve damage. The current international method is to use the iliac crest connection (Tuffer’s line) 3-1 as the body surface positioning mark of the lumbar spine, such as image 3 As shown, it is considered that the spine plane corresponding to the iliac crest line 3-1 is the intervertebral space 10 of the lumbar 3-4. However, a large number of studies have shown that this body surface marker is affected by factors such as gender, age, race, height, weight, pregnancy status, etc., and there are large differences between different individuals. Furthermore, the application of this positioning technique...
