Gastrointestinal (GI) bleeding is a hazardous clinical condition often resulting in morbidities and mortality in patients. After diagnosis, treatment options include administering proton pump inhibitors (PPIs), embolic agents to aid in the breakdown of the clots. At the same time, hemostasis can also be achieved using targeted endoscopic techniques and hemostatic forceps. During the procedure, the blood clots and other fibrous material are removed from the GI tract via suction from the endoscope instrument. However, this process is not overly effective with regard to removing the clots from the GI tract since the clots often cause blockages in the suction tubing of the endoscope and are not readily or easily suctioned. The objective of this project is to design a device to enhance the removal of such clots. The device under design as a result of this work consists of a small, conical, morcellating head to mechanically break up and aspirate the clots via a controlled oscillating movement before evacuation. The morcellating head will be encapsulated within a cone sheath to protect the GI tissue from damage. Furthermore, the device is operated through controls integrated with a conventional endoscope, allowing for ease of use and safety when operating the morcellating head as intended. Moreover, the device will attach to the endoscope's main accessory channel and will be disposable to reduce the risk of cross-contamination between surgeries. Overall, the device aims to efficiently remove blood clots from the GI tract by minimizing the risk damage to living tissue.
