Purpose  Enable surgeons to perform delicate and complex operations using a few tiny incisions with increased vision, precision, dexterity and control. [1]

System

Robot Information  FDA cleared for use in 2000 [1]  HD vision on one arm  Scaled, filtered movements  Four 8-axis arms Euler set EndoWrist

Surgical Specialties  Urology  Gynecology  Cardiothoracic  General Surgery  Colorectal  Head & Neck

Equipment  Surgeon console  Patient-side cart  EndoWrist Instruments  3D HD vision

Surgeon Console  Seated and more comfortable  Natural control position below display  Precise scaled hand, wrist, and finger movements  3D HD display with digital zoom /products/davinci_surgical_syst em/#components

Patient-Side Cart  Three surgical arms Fourth arm for vision system  Fixed rotation points increase precision  No automation: surgeon input required Safety checks

EndoWrist Instruments  Full range of motion  Specific instruments Incisions Clamping Suturing  Quick-release exchange ducts/davinci_surgical_system/featu res_benefits/instrumentation.html

3D HD Vision System  3D projection for surgeon  10x digital zoom  Separate display for assistants al.com/products/davinci_ surgical_system/features _benefits/ gical_system/features_be nefits/3Dvision.html

Advantages  Seated  Precise, filtered movements  Two surgeons in same space

Limitations  No haptic feedback [2]  Slower instrument exchange time  $2.5 million initial cost [3] $100,000/year maintenance  Only one camera

Conclusion  Minimally invasive surgeries Bariatric surgeries for obese patients  Help to eliminate some surgeon error  High cost Only practical for large surgical institutions
