Detailed description: The rigid video Esophagoscope is a 5 in 1 device which is a merger of a telescope, light source, endo-camera, sheath and instrumentation channel used for the purpose of esophagoscopy. It is made of a stainless-steel tube (figure:1B,6 and figure:2,5) of outer diameter of 8 mm and working length of 40 cm. The rigid instruments have a detachable obturator which is blunt which is put into sigmoidoscope before inserting into the esophagus to avoid injury to the patient. Since that is not possible in this instrument, this instrument is given a fixed and blunt round plastic tip (figure:1A 2,5 and figure:2,1) made up of heat-resistant plastic called Delrin (polyacetal). A video camera of 4 mm diameter and 22 mm length is fixed at the upper end of this Delrin obturator. (figure:1A,3 and figure:2,2). The video signal from the camera is carried by a bunch of 10 wires (figure:2,4) through the metal tubes and connected to the analogue to digital circuit (figure:2,7) placed in the cylinder made up of heat resistant plastic called Delrin (Polyacetal). (figure:1B,7 and figure:2,6) The output of this circuit is given to the male USB pin placed in the Delrin cylinder. This Delrin cylinder is placed perpendicular to the stainless-steel tube. Behind the Delrin cylinder, there is a round cap (figure:1B,9 and figure:2,9) made up of Delrin and has a diameter of 25 mm. This cap gives support to the main 8 mm stainless-steel tube. The instrumentation channel passes through this cap through a small hole. A USB wire connects the device to variety of devices such as desktop, laptop, android mobile phones and android based tabs. The device comes with software which needs to be installed on the display devices to see and records the images and the video. The video camera has 4 LEDs (figure:1A,4) which are powered by the power from USB pin. The LEDs illuminate the field during the procedure.
Structure and Design Features
The Rigid Esophagoscope’s most striking feature is its look. A series of wires is carried through a plastic box situated in the center inside the stainless steel tube. They are connected to an instrumentation channel and a USB outlet for the supply of gas or air during the procedure.
In rigid instruments used traditionally, the obturator can be taken out for safety. In the Rigid Esophagoscope, however, the obturator is permanent, and a plastic tip rounded off and Delrin—a heat-resistant plastic used in medicine—is placed on the distal end for safe patient application. The plastic tip prevents tissue trauma on insertion and manipulation.
The camera is supported on a string of ten wires which pass through the steel tube and end in a Delrin cylinder, the USB output also being contained within it. The 8 mm diameter tube is supported by the Delrin cap at the end of the cylinder. The USB interface is plug-and-play compatible with monitors, laptops, Android phones, or tablets, and live viewing and recording of the procedure are facilitated with special software.

The device has an instrumentation channel fixed in front at the lower end of the Delrin obturator. (figure:1A,1 and B,10 and figure:2, 3,12) It has a 2.5 mm inner diameter that accommodates a variety of 2 mm instruments. The back of the instrument channel is in a round plastic hub made up of Delrin plastic. (figure:1B,12 and figure:2,10). This round hub has a groove (figure:1B,13) Over this groove attaches a silicone washer (figure:1B,13) so that the air or gas should not leak during the procedure. At the side of the Delrin hub, there is a side channel with a female Luer lock (figure:1B,11 and figure:2,11) which is welded to the main instrumentation channel. Thus, gas channel and instrumentation channel are common. The gas channel allows for gas insufflation during the procedure. To this channel, a balloon of BP apparatus may be attached for air insufflation. Alternatively, gases such as O2 or Co2 can also be connected with a tubing.
The output of this circuit is given to the male USB pin. A USB wire connects the device to variety of devices such as desktop, laptop, android mobile phones and android based tabs. The device comes with software which needs to be installed on the device to see and records the images and the video. The device is reusable and can be sterilized by putting in Formalin chamber for 30 minutes or by Ethylene Oxide gas.
