A glue gun could banish the need for stitches after main surgical procedure and cut the possibility of wound an infection.
The hand held device squirts sizzling glue on to wounds, which bonds tissue firmly together earlier than steadily dissolving over a few weeks as soon as the wound has healed.
for centuries, medical doctors relied on stitches — or sutures — to close wounds, the use of a needle and sterile thread, always made from substances equivalent to s ilk or nylon.
The method is used whether someone is being handled for a minor injury, similar to a cut it really is unlikely to close by itself, or present process more invasive methods similar to open coronary heart surgery.
New frontier: The latest technique is used even if someone is being handled for a minor injury, reminiscent of a cut that is not likely to close on its own, or present process more invasive approaches reminiscent of open heart surgery
extra recently, using small steel staples has develop into usual, specially in foremost surgery akin to hip or knee replacements. The large skills is that they are tons faster to position in area than sutures.
however each suggestions carry some degree of chance, most specifically the danger of wound infection, as staples and stitches each penetrate the wound itself, permitting micro organism that is of c ourse on the dermis to get internal.
Staples also need disposing of once the wound has healed, as do many types of stitch — which carries an extra chance of infection and skill extra hospital journeys for sufferers.
The glue gun might overcome these complications.
clinical glue has been around due to the fact the Seventies. It changed into first developed for armed forces purposes, to assist soldiers in the box patch up wounded comrades immediately except they might get proper medical attention. similar to superglue, it bonds in seconds.
however some of the leading chemical compounds utilized in clinical adhesive, cyanoacrylate, may also be poisonous to human tissue, regularly causing ache and inflammation across the enviornment where it is used.
It also tends to harden too a good deal, decreasing the pliancy of the sk in or tissue and extending the chance of visible scarring.
different scientific glues are made from water-primarily based gels. These are less poisonous, however do not bond with the same power.
ordinary method: for centuries, docs relied on stitches — or sutures — to shut wounds, the usage of a needle and sterile thread, constantly made from materials comparable to silk or nylon
as a result, use of each kinds of medical glue is restricted to superficial dermis wounds where minimal bonding is required.
Now scientists at the Technion-Israel Institute of technology in Haifa, Israel, have developed a brand new category of glue that bonds tissue as with ease as stitches, however has not one of the toxicity of existing medical glues.
It consists of a modified type of biodegradable polyester known as polycaprolactone, which is already being investigated to be used in medical implants and drug coatings, as it step by step breaks down inner the body over a period of weeks or months.
The crew developed the glue in solid stick kind, like those used in craft work, so it's handy to save and use (many present glues are liquid).
as soon as the stick is positioned into the gun (in trials they used a standard store-purchased glue gun) it is heated to around 45c — hot adequate to show it right into a thick liquid, however no longer so scorching that it burns in shape tissue.
as it makes contact with human tissue, it cools to physique temperature — around 37c — and bonds to surrounding tissue, all of a sudden becoming a semi-strong substance strong adequate to shut wounds, but stretchy satisfactory to allow for ordinary move. The entire process, from application to bonding, takes simply seconds.
during laboratory checks, the hot glue was found to provide a bond basically as robust as present scientific glues, but with none of the toxic consequences, in response to consequences mentioned within the journal superior practical substances.
inside two weeks, experiments confirmed, the glue had dissolved into tiny particles which are absorbed with the aid of the physique and flushed out as waste, leaving the dermis practically scar-free.
The crew is now fine-tuning the glue to enrich its adhesive powers additional earlier than accomplishing medical trials on people in the subsequent couple of years.
