Vietnam Medic Makes Homemade Endoscope

Davian writes "As reported by the BBC a Vietnamese doctor has managed to create an endoscope using an apparatus consisting of lenses and a webcam, linked to a Pentium 4. Total cost of extra hardware - less than $1000." The doctor plans to also assist other local hospitals that are facing similar budgetary contraints.

      Part of the cost is caused by the need to take out insurance in case of a malpractice lawsuit, and to carry out usability and safety tests. You don't want to have to liquidate the entire company simply because some technician left his coffee cup on a floppy disk which led to the contents of the disk to be corrupted, leading to a missed diagnosis, and ultimately leading to the untimely death of an octogenarian.

      But a similar thing happened in Iraq. US Marines put together a water well inspection system out of a webcam, a torch, some rope and USB extension cables. Six months later a defence company comes out with the offical "military standard" version at around $100K per unit.

      Part of that is probably the roots of America's predominant religion - US Christianity stems from Puritan and other sects where being poor wasn't a sin but sloth was - hard work was a virtue (which fit in nicely with what was needed to survive in a foreign land)and neighbors helped each other through hard times when luck, not sloth, caused someone to fall onto hard times. Coupled with America's belief that you can triumph through hard work provides an American view of charity - help people get on their feet but don't let them stay on the dole forever - hence work fare vs welfare.

      Americans and America are generally generous people - in the context of how they view charity, which is to say not better or worse, but different.

      As a side note - America's disdain for socialism is rooted in the innate distrust of government and a belief in the "American Dream." American's don't like taxes (ask the English about that)so establishing a broad social net funded by high tax rates is very unlikely.

      I'm not american but german, but I've spent a lot of time in the US and believe you (and many other europeans) are misunderstanding some of the facts:

      Americans are not opposed to helping the poor on a personal level. In fact, americans spent a lot more (absolute and as % of GDP) on charity than europeans. In my experience, americans also have a culture of doing volunteer work to an extend that doesn't exist in europe. For example, I've seen a complete new school building be built by the student's parents. Some gave money, some gave machines, some did the work.

      What is different is the role of government in charity: while europeans see helping the poor mainly as a job of the state, americans do it themselves. If you look at the financial structure of shelters, soup kitchens but also museums and operas, you'll find that they are mostly financed by governments in europe, while they rely heavily on individual's contributions in the US.

      So it's nearsighted to say that Americans don't want to help the poor. They simply don't want the government involved, want to do it on their own terms and want it to be seen as what it is, namely charity, and not as some god-given right of other people over one's own money.

      Now, this doesn't mean there aren't some seriously crack-smocking right-wing jesus-nuts whose actions and words don't match. But that's another story.

      I'm going to call a bit of good ol' ignorance on this point (not on the poster but on the Americans he refers to). Socialism is classless. Anyone with a government connection would be a higher class than someone without, so either there is no government, or it's ubiquitous (which is the same thing, btw). The issue really is the path that Communist State countries have taken on their way to Communism (attempted anyway: there has never been a communist country). Corrupt politicians were abundant (and still are in the same area despite Democracy) and a lack of an infrastructure couldn't support the movement. The collapse was thus blamed on the system rather than the underlying infrastructure and corruption problems, and this is still hurting us today. Now anything that even appears socialist is frowned upon due to the mis-association.

Because a endoscope's purpose is to be inserted inside your body, especially inside supposedly sick bodies, it has to be steril so as to avoid contamination (AIDS anyone ?). Using an expensive endoscope (like in developped countries) forbids to use it once and dispose it. So endoscope are cleaned the best one can do without damaging it and re-used. This can lead to contaminations (in fact it's a cause for blood bank to refuse your blood). That's why a cheapper endoscope could be great for developped countries (on-time usage). But on the opposite it's not so great for second/third-world contries because I doubt a webcam is designed to withstand the heat, uv, and/or chemical used to clean the expensive endoscope, nor will it be disposed after use because cheap isn't there. This could be a major health problem. So I'm somewhat skeptical on the path taken by this doctor.

Some video cards provided MCI drivers which gave much more control, zoom, pan etc. Like the Matrox capture cards. All video endoscopic systems provided some sort of analog video output, composite, S-Video, RGB. The major systems were Olympus, Fujitsu and Pentax with a few minor players in specialty endoscopic fields.

    The hard part was actually remotely triggering the capture on the PC. We initially tried to get the specialists to tell a PC operator to press a button, but they just got frustrated with the whole procedure.

    Our next thing was to use the buttons on the scopes themselves (the flexible scopes have two dials for lateral movement and usually one or more buttons which can be assigned to various functions on each unit) so we slowly begged and borrowed one of each model of each type of scope unit so we could create interfaces to plug into them.

    Myself and a colleage researched over 100 units, measured signals, found suppliers of connectors, found manufacturers who could copy proprietary connectors (and there were about 30 different types of custom connectors in the end) and then wrote the code.

    We started using it for upper endoscopy and colonoscopies, but it was sold for ERCP's, MRI/PET/CAT scanning, rigid scope procedures and also for overhead cameras in surgery.
