Endoscope Cable


Shenzhen Yong Qiang Fu Industry is a medical cable industry leader manufacturer in the endoscope cable developing, customizing, developing and testing.  The customized endoscopy cables are designed to meet customers’ specific technical requirements for their advanced digital imaging devices, such as 2 in 1 android & pc usb endoscope usb borescope endoscope. Endoscope systems, similar to other imaging equipment systems, need to transfer signals &Power safely and reliably. At the same time, the connection (endoscope cable) between the patient and endoscope system must be smoothly, comfortable and Patient user-friendly. YQF can use its creative and experienced  strength for customized  products – often we are able to produce for as little as 500m and harnessed (prototype).
