A cranial laser locator

Abstract

The invention discloses a head laser position finder which comprises a head position finder and laser frames. The head position finder comprises a rectangular frame A, a rectangular frame B, a rectangular frame C, a rectangular frame D, a front intersection line, fixators, an amplifier A, an amplifier B, a gear B, a fine adjustment screw knob A, a fine adjustment screw knob B, a gear A and a limiting tube. The rectangular frame A and the rectangular frame B are symmetrically arranged on two sides of the head laser position finder, the rectangular frame C and the rectangular framed D are symmetrically arranged on the front side of the head laser position finder, the corresponding fixators, the amplifier A, the amplifier B, the fine adjustment screw knob A, the gear A and the limiting tube are arranged on a coronal view calibrator at the rears of the rectangular frame C and the rectangular frame D, the corresponding fixator, the gear B and the fine adjustment screw knob B are arranged on a sagittal view calibrator, the laser frames include a laser frame A and a laser frame B, laser emitting pens A are arranged on the laser frame A, and laser emitting pens B are arranged on the laser frame B. The head laser position finder has the advantages that the heads of patients can be stably fixed by the aid of the head laser position finder with the structure, accordingly, the clearness of images can be guaranteed during scanning, repeated scanning can be prevented, the patient examination time can be shortened, radiation can be reduced, and the service life of the head laser position finder can be prolonged.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to a cranial laser locator. Background technique [0002] At present, patients with cerebral hemorrhage need to undergo CT examination before minimally invasive hematoma evacuation. During CT examination, the patient's head needs to be placed on a headrest with arc-shaped grooves for CT examination, which is not easy to place in actual work. and fix the subject's head, resulting in a decline in the image quality of the CT head examination, and even the obtained image cannot help determine the position, and can only be scanned repeatedly, thereby prolonging the patient's examination time and increasing the patient's radiation dose. Caused too much load to CT machine again, had influenced the service life of machine. In clinical work, due to the inconsistency of the scanning position, positioning through CT reading results in inaccurate positioning. Some use vernier calipers for positi...

[0002] At present, patients with cerebral hemorrhage need to undergo CT examination before minimally invasive hematoma evacuation. During CT examination, the patient's head needs to be placed on a headrest with arc-shaped grooves for CT examination, which is not easy to place in actual work. and fix the subject's head, resulting in a decline in the image quality of the CT head examination, and even the obtained image cannot help determine the position, and can only be scanned repeatedly, thereby prolonging the patient's examination time and increasing the patient's radiation dose. It also caused too much load to the CT machine, which affected the service life of the machine

In clinical work, due to the inconsistency of the scanning position, positioning through CT reading results in inaccurate positioning

Some are positioned by vernier calipers, because poor development of the scalp on CT also causes positioning errors

Some devices are bulky, hard to fix and require multiple scans
