Collapsible guide NEEDLES FOR spinal-epidural block at a lumbar level

摘要

The utility model relates to medicine, namely to the anesthesia and could be used to impart epidural needle or introducer desired angle puncture ligamentous apparatus during spinal-epidural at lumbar level. Technical result of utility model is to provide guide needle when conducting spinal-epidural block in the lumbar midline approach the optimum for each level of the spine angle in the frontal and sagittal planes. This is achieved in that the utility model is a structure of the three elements, one of which is an element in the shape of a dihedron formed by two half-planes of equal width and positioned relative to each other at a right angle and having a length at least the distance between two spinous processes . On the outer side of the middle one of the half-planes rigidly fixed cylinder. The second element - a removable cylinder, one of the bases of which are the pins with the location and diameter corresponding to the diameter and location of the working cylinder base apertures. Both cylinders are of equal height, and the sum of their height does not exceed the width of the spinous process. On the grounds of both cylinders contacting grooves. The third element - bubble level with the shank, which is provided with two mutually perpendicular slots with possibility of inserting the element made in the form of a dihedron formed by two half-planes equal to the width of the half-plane.
