2.  Localized pain management surgeries require the use of three hands: one to insert a needle next to the nerve, one to hold an ultrasound probe, and one to thread the catheter.  This procedure requires the use of an additional assistant to lend the extra hand.  This increases the risk of contamination and the costs of the procedure

3.  1- To research existing technologies in flexible stabilization arms and adapt a new idea around these existing one.  2 - To design a flexible arm with interlocking and flexible joints for use with ultrasound probes to aid in surgery  3 -To produce a working prototype for future modification and development

4.  Flexible and movable arm with little resistance when out of tension.  When in tension, the arm must be rigid enough to resist movement.  Light weight  Durable  Accurate and Precise

5.  Gorilla Pod  Too much flexibility when rigid  Locking arm for organ manipulator (patent US 6,730,020 B2)

6.  Nurse - $30/hour = $30/one hour surgery  150 surgeries/year = $4,500 nurses salary  OR room = $1500/hour  Trying to cut procedure time down  Approximate arm cost goal ≤ $1000

8.  Built prototype flex arm  Working on alternate handle design solution  Testing the first flex arm design to determine force necessary to maintain rigidity in flex arm  Assessing issues with current design  Integrating a dial to apply tension vs. spring mechanism

11.  Construct prototype handle  Machine shop  Need to measure force required to move the rigid arm out of position while under tension  Build mounting base for the arm to attach to the handle  Work with mentor to get funding  Reinforce testing apparatus  Remodel links
