+# 病理管理模块 — 深度设计文档
+
+> **版本**: v1.0 | **编制日期**: 2026-06-07
+> **依据**: 《病理科建设与管理指南》+ 《临床病理质量控制标准》
+
+---
+
+## 一、业务背景
+
+病理诊断是手术后诊断的"金标准"，三甲医院必须具备:
+- 病理标本全流程追溯(从手术室到病理科)
+- 三级审核制度(住院医师→主治→副主任)
+- 病理报告质量控制
+- 肿瘤登记上报
+
+## 二、业务流程
+
+```
+[手术/活检/穿刺] → 病理申请单
+  ↓
+[标本采集] ←→ [条码打印] ←→ [标本固定(10%福尔马林)]
+  ↓ (运送至病理科)
+[标本接收] ←→ [标本核对(条码扫码)]
+  ↓ (不合格退回)
+[取材描述] ←→ [组织处理(脱水/包埋)]
+  ↓
+[切片制作] ←→ [染色(HE/免疫组化/特殊染色)]
+  ↓
+[初诊阅片] ←→ [上级医师审核]
+  ↓ (疑难病例会诊)
+[病理会诊] ←→ [最终诊断]
+  ↓
+[报告编写] ←→ [三级审核]
+  ↓
+[报告签发] ←→ [临床科室领取]
+  ↓
+[肿瘤登记] ←→ [随访]
+```
+
