Product name: Rigid Video Procto-Sigmoidoscope 10,15 mm
Trade name: USB Proctocam 10, USB Proctocam 15
Product Specifications: The rigid video Procto-sigmoidoscope, a 5 in 1 device which is a merger of a telescope, light source, endo-camera, sheath and instrumentation channel. It is made up of a stainless-steel tube with a blunt obturator in front containing a video camera with 6 LEDs and electrical wires with an analogue to digital converter circuit placed in a plastic holder at the middle of the device with a USB pin as output with an instrumentation channel and a side port for gas or air insufflation. It has two sizes 10- and 15-mm diameter. It has zero-degree vision and 30 cm working length.
Detailed description: The rigid video Procto-sigmoidoscope 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 proctosigmoidoscopy. The device is made up of a stainless-steel tube with a blunt obturator in front containing a video camera with LEDs and electrical wires with an analogue to digital converter circuit placed in a holder at the middle of the device with a male USB pin as output with an instrumentation channel and a side port for gas or air insufflation.

Complete specifications of Rigid Video Procto-Sigmoidoscope are as follows: It is made of a stainless-steel tube (figure:1B,6 and figure:2,5) with working length of 30 cm and outer diameter of 10 mm and 15 mm. The rigid instruments have a detachable obturator which is blunt which is put into sigmoidoscope before inserting into the anus to avoid injury to the patient. Since that is not possible in this instrument, this instrument is given a fixed and blunt round obturator as a tip. (Figure:1A 2,5 and figure:2,1) The video camera of is fixed at the upper end of this obturator. (Figure:1A,3 and figure:2,2). The video signal from the camera is carried by a bunch of wires (figure:2,4) through the metal tubes and connected to the analogue to digital circuit (figure:2,7) placed in the cylinder-shaped holder. (Figure:1B,7 and figure:2,6) The output of this circuit is given to the USB pin placed in the cylindrical holder. This holder is placed perpendicular to the stainless-steel tube. Behind the holder, there is a round cap (figure:1B,9 and figure: 2,9) This cap gives support to the main 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 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 an inner diameter in the range of 0.1 mm to 15 mm that accommodates a variety of instruments. The back of the instrument channel is in a round hub. (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 nozzle with a 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 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 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 instrument can perform a lot of endoscopic surgeries such as endoscopic biopsy for Hirschsprung’s disease and operative procedures such as polypectomy, coagulation of rectal ulcers, banding of piles etc. which are difficult for the conventional instrument. The picture quality is excellent due to the “Chip on Tip” technology and there is no image loss as in conventional instrument.
Intended application: It can do variety of diagnostic procedures such proctoscopy, sigmoidoscopy and therapeutic procedures such as endoscopic biopsy for Hirschsprung’s disease and operative procedures such as polypectomy, coagulation of rectal ulcers, banding of piles etc.
Method of using: 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.
