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.

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.
The advantages of the device over the conventional are as follows: It is a compact and lightweight device which weighs only 120 gm. It is 5 in 1 in the nature and is a unique merger of a Telescope, light source and endo-camera, sheath and instrumentation channel. It is commercialized at a reasonable cost of Rs.40,000 compared to Rs. 6 Lakhs of the conventional equipment. The picture quality is excellent due to the “Chip on Tip” technology and there is no image loss as in conventional instrument.
Intended application: The instrument can perform a variety of diagnostic procedures such as diagnostic esophagoscopy for strictures, foreign bodies, oesophageal varices and therapeutic procedures such as biopsies, oesophageal variceal therapy and dilatation of oesophageal strictures etc.
Class B
Method of using the device: The device is sterilized by Ethylene Oxide gas sterilization. The patient in lithotomy position with parts prepared and draped. The device is connected via a USB cable to the display devises and images and videos start streaming on them. The device is gently inserted into rectum and the side gas nozzle connected to C02 insufflator with 10 cm of water pressure and 10 Liters per minute flow. The illumination of LEDs adjusted to get a clear picture. The recta lesion identified clearly. A biopsy forceps passed through the instrumentation channel to get the biopsy of the lesion. Many operating forceps can be passed through instrumentation channel for various surgeries. Images and video recorded on a software installed on display devises. The device gently taken out and cleaned and sent back for sterilization.
