University of Pittsburgh researchers have developed the Easy Anastomotic System Instrument (EASI), a precision microsurgical device designed to facilitate the anastomosis of small tubular structures, such as blood vessels, without the need for expensive microscopes or specialized expertise. The EASI device ensures accurate suture placement, prevents common surgical complications like backwalling, and improves the overall success of complex reconstructive procedures
Description
ASI (Equidistant Anastomosis Suture Instrument) is a precision microsurgical device consisting of two primary components: a guide cylinder and a rod component. The guide cylinder, available in various diameters, features equidistant dents that serve as guiding divots for suture placement, ensuring consistent and reliable anastomosis. The rod component holds a microsurgical clip, providing stability and precision during the procedure. The device is designed to be inserted into the lumen of small blood vessels, maintaining vessel shape and alignment, which is critical for successful anastomosis.
Applications
- Vascular anastomosis
- Reconstructive surgery
- Microsurgical procedures in resource-limited settings
Advantages
EASI improves precision in suture placement, prevents backwalling, and reduces the need for expensive equipment and specialized training. It democratizes access to advanced microsurgical techniques and can be used for various small tubular structures, enhancing surgical outcomes and reducing complications.
Invention Readiness
The concept of the EASI device has been defined, and a prototype exists. The initial prototype will be produced using 3D-printed material and tested in a chicken thigh vessel model to assess its functionality and effectiveness. After successful testing and necessary refinements, the final version will be manufactured from metal or other durable materials to ensure reusability and widespread clinical application.
