| Issue/Objective |
Self-retaining retractors, such as the Omni table-mounted retractor, are essential for larger-scale procedures like C-sections, abdominal and trauma surgeries. They allow for consistent retraction force and positioning and reduce repeated contact with the surgical field that can introduce infection. However, these retractors are expensive and difficult for hospitals in Hawassa, Ethiopia to obtain due to expense and importation. Therefore, there is a need to create a table-mounted self-retaining retractor using materials and tools already available in their operating room.
|
| Methodology/Approach |
The solution consists of 12 identical metal strips screwed together at their ends to form 2 hexagons stacked on top of each other. Handheld surgical retractors are clamped in between the 2 hexagon rings using screws or clamps either side of each handle. The retractor position can be adjusted and then resecured in the desired position. Additionally, metal strips can be added or removed to increase or decrease the size of the ring. Stabilization of the device is achieved using straps that loop through the device and attach to the rails either side of the surgical table. |
| Results |
This device is able to hold multiple styles of handheld retractors without slipping against opposing hand resistance. We plan to quantify this clamping strength in the future and evaluate more retractor styles. |
| Discussion/Conclusion |
We emphasized using materials that are readily available in Hawassa, Ethiopia to allow for the intended users of the device to be able to manufacture it themselves, drastically reducing its cost. Additionally, this design is compatible with retractors already present in their operating rooms. Future work on this project includes quantifying the clamping strength, ensuring that the ring itself is more securely fastened in a way such that manipulating the retractors does not move the patient, and addressing challenges regarding the sterility of the device. |
