The external laser alignment guidance system of intracranial hematoma microscopic wound dissection and localization method

The invention discloses a kind of contactless positioning auxiliary devices for intracranial hematoma microscopic wound dissection, including fixed frame, right angle connecting rod, right angle connecting rod fixing axle, height adjustment device, horizontal extension arm, vertical telescopic arm, vertical direction laser aligner and horizontal direction laser aligner.Horizontal extension arm distal end is equipped with vertical direction laser aligner, and the vertical direction fan laser face of sending and place telescopic arm long axis are vertical, and light source is downwardly directed, provides the datum mark of guiding；Vertical direction telescopic arm distal end is equipped with horizontal direction laser aligner, and the fan laser face of sending can be rotated by rotation regulating mechanism along laser optical axis, and square regulating arm makes the lasing area and vertical direction lasing area remain vertical relation.The present invention uses the cantilever laser alignment guiding technique of non-frame, is continued precisely to be oriented to for puncture needle in art, contactless design increases surgical field of view, avoids the steric hindrance in puncture process.
