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!

because lightsabres cauterize the limbs they chop off.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
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?
And yet so many love to hate Jews and the Jewish State nevertheless. Go figure. . .

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.
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.
Someone predicted that as soon as something like this gets invented that a bunch of med students would get drunk and seal up the butthole of someone who passed out.
This is an important subject. Thanks for this stuff. lida,orjinal lida,http://www.lidasatis.org

Smivs on the intertubes!
So will we have to be underwater for the surgery?
Breasts, I mean. This is going to be heavily used to close incisions of breast augmentation surgery. We shall lose a weapon in our arsenal of 'true-fake' wars.
We are doomed.
I speak England very best
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!
...they had lasers on the INSIDE beaming out when ever their flesh is pierced? You know, like having lasers in the blood.
How come Marvel didn't yet come up with such an awesome character?
Would such a combination make the character some kind of a weird Wolverine-Cyclops hybrid?
What would Jean Grey think about that?

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.
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
Your Honour and Jury members,
I wasn't trying to cut the man in half with my laser, but only to sew him back together. I submit this slashdot article as evidence exhibit A.

I think I fist saw this in Logan's Run...
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"?
Seven puppies were harmed during the making of this post.
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.

I think the modern version of that would be using superglue. Both effective but fairly brutal & 'last resort'.
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?

The higher the technology, the sharper that two-edged sword.
What kind of rod does one use for that weld?
An inanimate carbon rod.
Indeed, I was disappointed to think that they weren't already doing this in medicine.
I for one welcome our newly graduated Sharks-in-residence.
(Though I hear they tend to ignore any patient that isn't bleeding...)
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.

There.. corrected that for you. =)
Gladly, they mentioned the inventor Abraham Katzir (a physicist at Tel Aviv University).
All too often, it''s the surgeon who gets all the credit when, in fact, all this wonderful medical technology is created by engineers and whole team - a lot more people than the guys who like to pose as heroes.

Now all we need is an antibiotic gel that instantly closes and heals small wounds, and a way to give doctors surgical bullet time by waving pentagrams over the patient, and we're all set!
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.
