Energy-cutting Training Model for Robotic Blood Vessel Dissection

Last updated: 4/16/14 1:19am

Summary

Enter a short narrative description here

  • Students: Shayer Chowdhury
  • Mentor(s): Dr. Gyusung Lee (glee49@jhmi.edu), Dr. Mija Lee (mlee204@jhmi.edu)

Background, Specific Aims, and Significance

  • Robotic surgeons have expressed a desire to spend more time on blood vessel dissection preparation
  • Want to practice different techniques: blunt dissection, sharp dissection, and electrocoagulation
  • Current practice models run up to $75-80 and are not reusable
  • Want a realistic phantom training model, but one that is also cheap and efficient to make, and potentially reusable
  • Current state: Lack of a cheap, effective, and reusable blood vessel dissection phantom for robotic surgery training
  • Approach: Model creation, then frequent updating and testing through user feedback with surgeons at JHMI
  • Goal: Create a comprehensive inanimate surgical training model for sharp/blunt dissection and blood vessel electrocoagulation

Deliverables

  • Minimum: Expected date: March 20th
    1. Blunt/sharp dissection model prototype
  • Expected: Expected date: April 1st
    1. Modified and improved blunt/sharp dissection model with user feedback and experimentation with other materials
    2. Electrocoagulation model prototype
  • Maximum: Expected date: May 4th
    1. Completed blunt/sharp dissection and electrocoagulation models
    2. Integration into future standard robotic surgery training practicums
    3. Production and storage of models for future planned usage

Technical Approach

Dependencies

- Access to mentors

  • Weekly meetings with Dr. Gyusung Lee and/or Dr. Mija Lee

- Access to lab space to create phantom media

  • Available lab space at MISTIC at the JHMI (12th floor of Blalock)
  • MISTIC will also be used as headquarters and main address for delivery of materials

- Cost to afford material

  • Material will be fairly inexpensive, since cheap and efficient is our goal anyways
  • Dr. Lee is in the process of obtaining a small grant to fund the project
  • Attempt to use recyclable lab material

- Access to relevant literature

  • Articles available online and at the MSE Library

- Access to surgeons who are willing to practice on and evaluate the effectiveness of the model prototypes

  • Dr. Lee will arrange and work with surgeons at MISTIC who will participate in testing out prototypes and commenting on shortcomings and successes
