Kosin Technologies is dedicated to helping the Urologists who have very little or NO HELP to perform Ureteroscopies by making the procedure easy and hassel free. Since it’s inception in the mid 80’s, Ureteroscopy has been a 2 person procedure. One ( The Surgeon ) to perform the Ureteroscopy and the second to help him/her with irrigation to be able to visualize. The current devices that are on the market requires the use of 2 hands, or a hand and foot, or an assistant to irrigate. In most places in the United States (and to a large extent ) the rest of the world, assistants or personal trained in Ureteroscopy are an exception and not the rule and the Urologist struggles with what they have and do their best to accomplish the goal (TASK).  Kosin Technologies have a new patented and FDA approved device that will help the Urologists perform the procedure with little or no help.  It is a MULTI FUNCTIONAL DEVICE that is compatible with all Ureteroscopes, make, models, rigid, semirigid or flexible and the SURGEON CONTROLS THE FLOW WITH THE SAME HAND HOLDING THE URETEROSCOPE leaving the other hand completely free for laser, basketing, brushing  etc.   In addition to being an irrigation device, it has an INJECTION PORT with a check valve built into it to be able to inject contrast, aspirate debris and blood clots, flush, perform cytologies and in difficult cases even be able to pass a guide wire or a small basket through it.  This is the Universal Piggyback Irrigation System or the UPIS. The device does more than what the current devices do, have more features than other devices have and it is ergonomically superior. Although designed for ureteroscopy, it can be used for any endoscopic procedure that requires irrigation, for example, Hysteroscopy, Neuroendocopy!
