+MAVIS is a microsurgical dataset comprising 19 videos of artificial vascular anastomosis procedures performed by three expert microsurgeons at Korea University College of Medicine, Republic of Korea.  
+For each video frame, it provides:
 
 - **Pixel-level segmentation** of seven tool categories  
 - **Frame-level workflow annotations**: surgical stage, phase, and step  
 
 This dataset enables research on both surgical tool segmentation and surgical workflow recognition in ultra-fine microsurgical environments.

 ### Stage–Phase–Step Hierarchy
 
-The workflow annotations are organized into six **Stages**, each containing one or more **Phases**, which in turn consist of individual **Steps**. Below is the full breakdown with descriptions:
-
-1. **First tying** (forming the first knot)  
-   1. **Phase: Suturing** – place and position the suture  
-      - **Needle holding**: grasp the suture needle securely with the needle holder  
-      - **Needle passing**: insert the needle through both edges of the vessel and pull it through  
-      - **Needle dropping**: release the needle at the optimal position for tying (≈5 o’clock)  
-   2. **Phase: Knot tying** – create the knot  
-      - **1st knot**: wrap the free end of the suture around the instrument and tighten  
-      - **2nd knot**: repeat wrapping in the opposite direction and tighten  
-      - **3rd knot**: final wrap to secure the stitch  
-   3. **Phase: Cutting** – trim excess suture  
-      - **Cutting**: use scissors to sever both ends of the suture (can cut both at once or sequentially)  
-
-2. **Second tying** (forming the second knot at a rotated position) (6개 stage가 되려면 120°, 180° tying을 분리해야 하는데 설명을 추가할지?)
-   - *Subtasks*: identical to First tying (Suturing → Knot tying → Cutting)  
-
-3. **Front side tying** (additional knot on the front face between first and second)  
-   - *Subtasks*: identical to First tying  
-
-4. **Flip** (reorient vessel for back‐side access)  
-   - **Phase: Flip** – flip the vessel clamp  
-     - **Flip clamp**: reposition the clamp so that the vessel’s backside faces the camera  
-
-5. **Back side tying** (forming knots on the backside between first and second)  
-   - *Subtasks*: identical to First tying
