The Rigid Video Ureterorenoscope is characterised by two semirigid tubes fixed to each other, one below another with a holder at the middle end. The upper tube is the camera channel and the lower tube is the instrumentation cum irrigation channel. It has at the back end a female Luer lock. The device has a posterior disposable bridge which can be replaced easily. The bridge has a side channel for irrigation. A Bi valve fits to the side channel of the bridge to control water flow during the procedure. The bridge has a posterior end with an iris mechanism to control water flow. It has an outer diameter of 7.5 F and instrument channel of 4.5 F with a working length of 45 CM.
The upper tube is the camera channel and has a tubular color video camera with white light emitting diodes (LEDs) for illumination fixed at the tip thus does not require a separate light source as in traditional equipment. The lower tube of the device is a straight instrumentation channel that passes through the holder and ends in the posterior end as a female Luer lock. The same channel also acts as an irrigation channel for irrigation of fluid during endoscopy procedure. Fluid is passed through the side channel of the disposable bridge by attaching it to a disposable Bi valve. On other port of Bi valve, suction can be attached. The lever of the Bi valve can start and stop fluid passing to the tip of the scope into the body as well as can switch between suction and irrigation. Instruments are passed through instrumentation channel through a hole in the posterior knob, having an iris like washer. It avoids fluid leaks around the instrument; the fluid can pass around the instrument and the vision during endoscopy remains clear. Thus, the device has an integrated irrigation and suction system, allowing for simultaneous fluid management, thereby minimizing procedural interruptions and maintaining a clear field of vision.
It is extremely light weight with weight of 50 Gm compared to 500 Gm for the peers. The device is designed with a lightweight ergonomic structure ensuring ease of handling and reducing surgeon fatigue during prolonged procedures.
The device has a USB pin as output at the back end and a USB cable connects the device to a variety of devices such as desktop, laptop, android mobile phones and android based tabs and with a software installed on the display devices and the images and video can be seen as well as recorded on the display devises.
