Low-cost Laparoscopic Surgery with Tele-mentoring (2018-2019)
For much of the 20th century, surgeons advanced the techniques of traditional open surgery. In the 1980s, the field of surgery advanced further with the development of laparoscopy. This technology allowed surgeons to make two to four small incisions and operate with an intra-abdominal camera and instruments. Benefits of laparoscopic surgery compared to open surgery include decreases in pain, recovery time, intra-abdominal scar tissue, wound infections, abdominal scar size, wound breakdown and length of hospital stay. However, laparoscopic surgery is expensive and demands a great amount of infrastructure to maintain the equipment. These costs are prohibitive to low- and middle-income countries, and therefore most surgeries in these countries are performed with the traditional, open approach.
This Bass Connections project’s goal was to develop a low-cost, reusable laparoscope appropriate for use in a low-income country. They aimed for a design that allows images to be transferred over the internet, enabling surgeons in high- and low-income countries to interact in real-time during surgical cases, thus allowing for remote mentoring or “tele-mentoring”.
The team successfully produced two prototypes: ReadyView Laparoscope and ReadyView Lift Retractor. The ReadyView Laparoscope has a better resolution than the standard of care laparoscopic and an equally bright light source. The prototype is powered by a laptop computer and displays the image on a laptop computer. The prototype can be built for $120 (in comparison to the current $216,000). The ReadyView Lift Retractor was created to eliminate the need for carbon dioxide insufflation and constant pressure regulation/constant power supply. In 2019-2020, the team plans to continue work on the prototypes.
