Customer Requirements
In today’s medical field, endoscopy is widely used, in addition to image transmission, therapeutic functionality is also required. Our customer, a medical endoscopy equipment manufacturer, ran into the problem that saline flushing was used through the empty tube that caused the backflow of saline and foreign objects from the optical channel to the handle, blockage at the tip, resulting in the loss of image and an increased risk of infection for patients. Therefore, the customer contacted SC to assist re-design the particular case.
Challenge Review
Because the endoscope contains an empty tube, Supreme Charger addressed the difficulties of sealing cable during production, preventing foreign objects and bacteria entering the cable during surgery, contaminating the endoscope, and causing patient infection. The endoscope can withstand the pressure and steam of high-pressure sterilization machines for repeated disinfection.
