Stop Bleeding of the Carotids

Preconditions (Signals received before entering this step)

Exit Conditions (Signals received while in this step that prompt a transfer)

Condition Next Step Description
Patient_Dead Done The patient is dead so the surgery is clearly finished.
Carotid_Not_Bleeding
Cotton_Fully_Removed
Pinces_Outside_Skull
Final Hemostasis After wounding and fixing the carotids, the surgeon does not continue the extraction of the tumor. But he still has to ensure perfect hemostasis before closing up the surgery.

Haptic Constraints Active for the Duration of this Step

Constraint Name Purpose
Chiasma_Repulsion_Close_Range Standard

The tip of the pinces has separated from its contact with the sinus Pinces_Sinus_Separated
The cotton has come into contact with a carotid Cotton_Carotid_Contact
Upon entering this state, trigger this signal regardless of what els is going on, because from now on we don't care if we've left a piece of tumor or pituitary loose in the space or not. Loose_Tissue_Abandoned_Off
The cotton has separated from its contact with a carotid Cotton_Carotid_Separated
The patient has died. Not cool!! Patient_Dead
