Introduction

Background of Standard Revision and Technological Evolution

As an alternative version of GA/T 168-1997, this standard mainly aims at systematically upgrading the mechanical injury autopsy technology. Compared with the 1997 edition, the main technical evolution is reflected in:

Comparison dimensions	1997 edition	XXXX edition
Terminology system	Not clearly defined	Five new types of injury terms (Articles 3.1-3.5)
Inspection scope	Toxicant inspection is not included	New Chapter 8 Toxicant Inspection Requirements
Technical methods	Mainly traditional dissection	Introduction of virtual dissection technology (6.6.1.3)

Core Inspection Technical Specifications

1. Injury Classification Standards

For the first time, the standard clearly defines professional terms such as abrasions, contusions, and traumas:

Intradermal hemorrhage: bleeding in the dermis, which can reflect the characteristics of the wounding object (Article 3.4)
Intertissue bridges: characteristic manifestations of blunt instrument wounds (Article 5.3.4)

2. Technical points of anatomical inspection

Typical case: The inspection of gunshot wounds needs to complete:

Morphological identification of the shooting entrance/exit (6.6.1.1)
Three-dimensional trajectory reconstruction (6.6.1.2)
CT-assisted bullet positioning (6.6.1.3)

Implementation suggestions and precautions

1. Collaborative application of multiple technologies

The standard emphasizes the combination of virtual dissection technology and traditional methods:

Technical means	Applicable scenarios	Standard clauses
X-ray/CT	Bullet positioning, fracture detection	6.6.1.3
MRI	Soft tissue injury assessment	6.6.2.2

2. Special sample handling

Note in explosion cases:

Fingernail extraction (6.6.2.3)
Toxicological examination of lung tissue (6.6.2.3)
