Measurement device for scar or pigment change of maxillofacial region

Abstract

The invention discloses a measurement device for a scar or pigment change of the maxillofacial region. The measurement device comprises a supporting platform, upper supporting legs are fixedly installed at the left end and the right end of the supporting platform respectively through telescopic rods, lower supporting legs are movably installed at the lower ends of the upper supporting legs throughinserting rods, a computer is arranged on the supporting platform, a straight groove is formed in the middle of the lower end face of the supporting platform, a gear rack is fixedly installed at thetop of the inner cavity of the straight groove, a sliding groove is fixedly formed in the left side and the right side of the lower end of the supporting platform separately, a movable device is movably installed in the inner cavity of the sliding groove through a sliding block, a three-dimensional laser scanner is installed at the lower end of the movable device, and a laser range finder is fixedly installed at the lower end of the movable device. Through the three-dimensional laser scanner, body surface data of a human body is scanned, then transmitted to a processor and displayed through CAD software, the scar on the body surface or face is clearer, and measurement is more accurate; original data of measurement is stored in a computer hard disk, people can have access to the original data at any time, and tracing is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for measuring maxillofacial scars or pigment changes. Background technique [0002] When an injured person is injured or dies due to an accident, the forensic doctor needs to examine and measure facial or body surface scars or scars and pigment changes of the injured and / or deceased, especially facial scars or scars and pigment changes The measurement of area is critical to the correct application of the standard clauses. It needs to be accurate to the millimeter level, and it is clearly required that photos should be kept, and a lifetime responsibility system for appraisal should be implemented. For those with a small area and a relatively flat area, at present, computer software is mostly used to measure the area after film tracing, and two-dimensional images of the measurement area can also be obtained by drawing, photography, etc., and the area measured by t...

Problems solved by technology

However, for those with a wide range of uneven facial parts that may reach the critical value specified in the standard clauses, the aforementioned method obviously does not meet the requirements due to the single measurement data obtained and the simple calculation method, and scars and / or pigment changes will cause Changes due to the extension of time, it is difficult to judge whether the measured data of the original identification is accurate

Although it is possible to obtain 3D images through 3D CT imaging, 3D MRI imaging, 3D laser scanning, stereo photography, Moiré method, acoustic 3D imaging, etc., it is more accurate to obtain 3D parameter information of human body structure, but it has not yet been seen. To related devices specifically for the measurement of maxillofacial scars or pigment changes
