Introduction
Core changes in the standard revision
| Comparison dimensions | 1997 edition | XXXX edition |
|---|---|---|
| Dissection techniques | Traditional cardiac dissection methods | Newly added Six-knife cardiac dissection techniques |
| Scope of inspection | Basic organ inspection | Inspection of 12 special parts such as peripheral nerves and pituitary gland |
| Pathological requirements | Conventional pathological sections | Mandatory requirement for combined diagnosis of biochemical inspection and toxicological analysis |
Key technological breakthroughs
Six-knife cardiac dissection method
The standard specifies for the first time the systematic cardiac dissection process:
- Right atrium incision: Cut straight from the inferior vena cava to the superior vena cava, and simultaneously explore the tricuspid valve
- Pulmonary artery inspection: Precisely cut 1 cm to the right of the anterior interventricular groove, retaining the left coronary artery branch
- Myocardial cross-section: Use an "8"-shaped section to observe the scope of myocardial infarction, with the spacing controlled at <1cm
Typical application cases
Pulmonary embolism inspection procedures
In a case of sudden death of a 45-year-old male, the forensic doctor followed the standard clause 5.1.3:
- In situ cutting of the pulmonary artery trunk to the hilar branch
- A 12 cm thrombus was found embolizing the right pulmonary artery
- Through tracing through the gastrocnemius cross section, a deep vein thrombosis in the lower limb was found
Implementation suggestions
Multidisciplinary collaboration mechanism
It is recommended to establish a pathology-biochemistry-imaging collaborative workflow:
| Phase | Operation points | Technical support |
|---|---|---|
| Preliminary investigation | Collect implantable defibrillator data | Medical equipment analysis technology |
| Dissection process | Synchronous recording of high-definition images | GA/T 1198 specification |
| Pathological diagnosis | At least 5 myocardial slice sites | Immunohistochemistry technology |
