Surgeons Weld Wounds Shut With Surgical Laser
Ruach writes "The promise of medical lasers goes beyond clean incisions and eye surgery: Many believe that lasers should be used not just to create wounds but to mend them too. Abraham Katzir, a physicist at Tel Aviv University, has a system that may just do the trick and is proving successful in its first human trials."
Now that is a surprise. That always struck me as funny, the way they just beamed at some wound and it closed.
Was there a shark attached to it?

As usual, the summary misses the interesting bit. Using lasers to seal wounds is old news - I first read about it in the Readers Digest about a decade ago. What's new here is a mechanism to prevent overheating.
Is there anything they can't do?

It would be interesting if this could be used in the creation of people like Wolverine, only the body doesnt need mingboggling regeneration capabilities, they just weld the wounds shut. Sign me up!

This would be great if your leg had been bitten by a shark!

First, they had to determine the optimal temperature at which flesh melts but can still heal (about 65 degrees Celsius).
I don't envy the test subjects.
... the false Laser will take it from you.
TFA "compares" two wounds (http://www.technologyreview.com/files/22023/laser_x220.jpg) and then states that "After 30 days, the laser-bonded scars ... appeared smaller than those done with a needle and thread" - and yet it is pretty obvious that this is because the laser-bonded scars were smaller incisions to start off with. In terms of prominence of the remaining scar, it looks like there's not a lot in it, but that perhaps the laser-bonded scar has either a darker area or a scab still remaining in the middle.
Perhaps next time, they should compare results with incisions of identical length?
sharks with friggin lasers on their heads?
I mean the poor thing is going to keep biting and not understand why the pray wont die.
You can hate and love something at the same time, for different reasons.
It has nothing to do with religion
The whole point of this new method is that you can cauterize a wound without charring the flesh, instead just melting it. The optimal temperature for this is, apparently, 60-70 deg. C., and this is maintained using feedback from an infrared sensor on the "soldering pen". They apparently also use a water soluble protein as "solder". The scars on in the TFA pictures look real nice. Wonder if the wound will hurt more or less than a conventionally sealed wound?
A clean cut can heal in a way that has minimal impact. When you melt flesh you're doing lasting, siginificant changes that doesn't really heal. You'll change a thin white line that fades with a tan to a large pink splotch on the skin that won't really ever go away.
No, TFA shows two sample pictures, and TFA didn't do any comparison at all, especially not any based on these particular pictures. The *doctors* compared wounds on ten patients and decided that the laser-bonded scars were healing better, which is what the article reports.
The point of the pictures isn't so *you* can second guess the doctors (who believe it or not know an awful lot more about this than you do). They are there to give a quick visual impression of what's going on, to complement the real detail contained in the text of the article.
If you really want to double check the results, go find the original research paper. However I think you'll find it's rather longer and not quite so interesting to read.
Yeah, next they'll be knocking the Nazi's even though they made massive advances in rocket technology. Why can't everyone realise that as long as you make scientific breakthroughs people should love you regardless of anything else.

People like Wolverine..........as long as they can take time out after every injury to run a "fricken' laser" beam over their wounds.

What kind of rod does one use for that weld?
TFA states that several people underwent clinical trials... for a FLESH-WELDING LASER.
Anyone who hears those words and still goes in for experimental surgery is probably the bravest person on the planet. I salute you!
That's actually a common misconception.
US foreign aid to Israel is limited to commodities purchased back from US companies: Israel cannot spend that money in any other way.
The money goes back to US companies like Boeing or Lockheed martin when Israel purchases fighter jets.
You can rest assured, that university research projects in Israel don't see a dime from US tax payer money. (Unless it's some US D.O.D joint effort)
Sigs are for the weak.
...they had lasers on the INSIDE beaming out when ever their flesh is pierced? You know, like having lasers in the blood.

Nope they just have a lot of money that they would've otherwise spent on those things to spend on research instead
The foreign aid to Israel is given out since the US recognizes the strategic importance of Israel in the middle east - it is vital to promote US interests in the area.
And yes, the game is played both ways. Both US and Israel gain from the foreign aid - i just don't want people to think that the US is spending money in Israel without gaining anything from it. The US is not a philanthropic organization and Joe six pack is definitely not funding the Jews because they tricked him into it.
Sigs are for the weak.
From TFA:
"All a surgeon has to do is move the pen's tip along the cut, strengthening and sealing the weld with a solder of water-soluble protein."
It looks a lot like very controlled cooking and I suspect the protein used to connect the tissue denatures in the process. It's not welding, it's hot-melt glue.
Still very cool.
Honest question, what does the US gain from the money it gives to Israel? Is that gain cancelled out by the negative views of the US throughout region as a result?
meh
I'm confused here, hasn't stuff like this been done for a long time now? (pre 2000 at least?)
I know they have been using them to cut pre 2000 for sure, but i'm sure i remember seeing flesh welding lasers. (and to burn away tattoos as well)
Anyone else? Or did i seriously just wake up in the wrong universe today.
It doesn't seem right to me, the sky is blue, i was pretty sure this was Winter, not the middle of Hazlug.
Firstly, 65C, isn't that the just above the heat of a warm bath, and doesn't a sauna reach up to 110C ? Second, since when does a skin melt?
Who can give some more indepth information about this?
I think we can keep recursing like this until someone returns 1
The US gets to stop an country getting annihilated, that shares similar values and willing to get its hands dirty (at the expense of political backlash). And no, the gains are not canceled out as the people that hate Israel are not the sort of people that ever would not hate the United States.
I've got a great story after talking with a girl who fled Iran after her family was persecuted for not being Islamic (belonged to some weird minor regional religion). Though it's an anecdote, I've come to believe the Muslims hate people for not belonging to their religion. And even if it was only 5% (Although, I'm inclined to believe it's much much higher) it's completely incompatible with our society. Imagine if 5% of Christians started stoning atheists..

First of all, plenty of Christians have killed and will kill a non-believer. It's documented well, and countless times.
Funnily enough 10% of Jews in Israel *will* also stone your ass if you drive through a particular street on a Shabat, if you happen be Palestinian and live near certain settlers and if you dare to drive/eat/smoke in their vicinity on a Yom Kippur.
Believe me. I live here. The latter example actually took place in Akko recently. An Arab drove through Akko (which is an Arabic city), ended up on a Jewish street, got stones thrown at his car and subsequently *he* was arrested for it.
Then there are the boys who immigrate from Russia who get bullied into circumcising themselves at the age of 20 by their peers in the Army. That one's about brainwashing *and* self-mutilation as a consequence of it, and that's still done by the more secular Jews, that's not even the work of your 10% of orthodox fringe idiots.
Now my boy would be considered Jewish because his mother is an Israeli Jewess, so don't come to me and cry anti-semitism for what I've just pointed out either, please.
Having said that, I think the Christians should be very, very quiet about the Muslims killing those who are not Muslim because we all know what religion brought on the Spanish Inquisition, which hunts, the 100 year war, the Crusades and many other calamities that were aimed towards non-believers.
In 1987 George Bush Sr said an atheist can never be considered a citizen and an atheist can never be considered a patriot. Because this is one nation under God. And he got elected president. Twice. And then his son. Twice.
So please climb off that horse and shut up about the Muslims. Humanists and an atheists can say something about Muslims. Christians and Jews are just part of the same mob, however.
I think I fist saw this in Logan's Run...

Sure it's happened lots historically, but all present day cases are really just psychopaths.

It cuts both ways. There are many mountain regions in Israel that you can't go without also risking being stoned.

And hopefully that is more the exception than the rule. But keep in mind the solution isn't to be peaceful when faced with a violence. I think it would be relevant to cite the holocaust..

It happens in the US military too, so you can hardly call it religiously motivated (more conformity).

Why would I? You've said nothing remotely anti-Semitic.

The Christians certainly can't be critical of Muslim history (they were imo much worse) but at least they've progressed. :P

I chucked at this. Your counter example to a religion that sanctions the killings of "infidels" is a *comment* pandering to the hard religious.
:P). But even so, I can admit they're really not being actively aggressive to my choice (or lack of) religion.
But even so, I'm surprised someone could believe that (along with things like 'there are no atheists in the fox holes'). And I honestly don't like the religious any more than you, nor would I ever vote for a party that supports state religion in any respect (Unless it was atheism, I'd be all up for that
So please climb off that horse and shut up about the Muslims. Humanists and an atheists can say something about Muslims. Christians and Jews are just part of the same mob, however.
So I can climb back on? :P And yes, I agree that Christians and Jews can be lumped in the same boat.
To instantly send the cost of that $7500 surgery to $15,000. After all, SOMEONE has to finance, maintain and insure that $300,000 laser machine because a $2 package of 3-0 nylon monofilament just won't do nowadays. Hey do we still have the machine that goes "bing"?

hmm isn't that a modern way of the old heat a knife over a fire then burn the wound closed with the side of it like on movies?
I would imagine it's much less painful and leaves less of a scar.
hmm isn't that a modern way of the old heat a knife over a fire then burn the wound closed with the side of it like on movies?
I think the modern version of that would be using superglue. Both effective but fairly brutal & 'last resort'.
George Bush Sr was president for one term. Also, the past does not justify the present. If people are being killed simply because they don't share a faith they are still BEING KILLED. It doesn't matter that roles may have been reversed 50, 100, or a thousand years ago, that is done and gone. Everyone should complain and complain loudly regardless of their faith. So please climb off that horse and realize that this is about people and we all have equal rights to complain Christian, Atheist, Musilm and Jew.
Seems more like soldering as your adding a connecting agent. Glue would require time to dry, where soldering only requires cooling.
If it were anything else...
I think a better analogy would be that this is like soldering for the body.
Can anyone translate this to car analogy?

Totally false. In contrast to other receivers of US foreign aid, Israel is allowed to spend the money in what ever way it wants. And they do have a strong domestic weapon industry which means that the aid goes to the Israeli military buying Israeli planes and Israeli tanks.

Wrong again, HateBreeder. Oh how ironic it is that that is your choosen nick..
The indirect costs in goodwill the Israeli-American special relationship is causing American companies is orders of magnitudes bigger than the direct aid cost which is 5 billions/year. Companies have a much harder time penetrating Arab markets thanks to the US pro-Israeli stance. Coca-Cola for example was boycotted in Middle East. The whole oil embargo which caused the US economic recession in the late 70's was a direct result of the aid to Israel. From a purely economic viewpoint, the aid has been a huge freaking burden with no return whatsoever. Not even gratefulness.
Oh, and "the Jews" do tick, coerce and bribe politicians to keep giving money.

Right and my quick visual impression is that scaring might be smaller, but it's far nastier looking.
Actually, superglue is quite effective at closing skin (though large wounds still need to have the deep layers closed). The monomers used are designed not to produce as much heat during curing as the home-use ones, but they're still cyanoacrylate adhesives.
Superglue was developed as a wound adhesive so it's not surprising it's quite good for that purpose.

Oh, gee, thanks for the permission. I'm an atheist, and I'd support Israel over the rest of the Middle East any day of the week including the Sabbath. Forget religion; they're the only functioning democracy in the Middle East, and they're surrounded by countries that want to wipe them off the map. I'd say that makes them worth defending, just a little.
Downmodding is the refuge of the weak. Don't downmod, make a better argument!
You are right, it has nothing to do with religion. It has everything to do with values: education and minding you own business to better better yourself. That leads to progress, and some progress that spills over to others. It has to be said because it is relevant that so much good progress comes from Israel, and not quite so much from the surrounding dictatorships that just want to annihilate it.
Nota bene: Egypt gets comparable amounts of foreign aid from US. Not quite so much to show for it.
Gladly, they mentioned the inventor Abraham Katzir (a physicist at Tel Aviv University).

The comparison was right there in the caption of the image. Like it or not, the article directly implied (by placing the statement in the caption of the side-by-side photos) that this was a direct comparison of laser-bonded scars with needle and thread scars. Yes, you and I might both realise that it either wasn't a comparison, or was a very poor one. The average reader might not. One scar was long enough to require multiple stitches as evidenced by the scarring - the other couldn't have fit more than a single stitch. But, you know, feel free to make smug comments about how parent doesn't know anything and ignore the fact that the article itself is blatantly misleading.
