Operative technique - Coggle Diagram

- - - - tocugh tissue
      - tissue under tensiion
      - minimal tissue traume unless there's iatorogenic damage
      - pencil grip for stab incision
      - finger grip for long incision
    - - cut tissue below skin, blunt dissection, undermining tissue
      - controlled cutting, good for flaccid tissue :smiley:
      - shearing tissue trauma :unamused:
      - Metzenbaum
        
        blade = 1/4 length of instrument
        
        incision or sharp/blunt dissection of finer tissue
        
        straight--> greater mechanical advantage
      - Mayo
        
        blade= 1/3 length of instrument
        
        incision of dense, heavy tissue e.g. cartilage
        
        curved--> greater mobility + visibility
      - Utility scissors
        
        straight blades with blunt-sharp tips
        
        inanimate objects
      - Ligature Scissors
        
        cutting suture ONLY
        
        one blade is serrated
        
        finger rings don't meet when blades are together
        
        fine + precise cutting
  - - - pencil grip steadies tissue for action
    - - Allis (sharp teeth)
        
        holds tissue firmly
        
        only holds tissues that will be removed
      - Babcock (no teeth)
        
        holds tissues atraumatically e.g. stomach, pericardium
      - Doyen/Bowel
        
        atraumatic, don't meet in middle
        
        clamp intestines to prevent leakage of gut contents
    - - Mosquito
        
        fine + small
        
        hold individual fine blood vessels
      - Kelly
        
        medium sized
        
        tips partially serated
        
        holds large blood vessels +/- tissue
      - Rochester Carmalt
        
        longitudinal sections
        
        large
        
        holds tissue + blood vessels e.g. uterus during spay
  - - - standard
    - - cutting blade
    - - asymmetrical
      - no ratchet
      - short
    - - large needles + suture
    - - fine needles + suture
  - - - Senn
      - Army & Navy
      - Langenbeck
    - - Baby gelpi + Gelpi
      - West + Weitlander
      - abdomen + chest
        
        Finochietto
        
        Gosset
