New Surgical Superglue in the Works

New surgical super glue is preparing to replace the sutures


A team of researchers from the hospital "Brigham and Women ”, in Boston, announced the creation of a new type of surgical glue, a material capable of sealing cuts in hearts or blood vessels with efficacy. 

Η superglue (υπερ-κόλλα) εμπνεύστηκε από τα σκουλήκια sandcastle, που είναι πλάσματα που ζουν στις ακτές της Καλιφόρνιας και περνούν τη ζωή τους πάνω σε βράχια και σε πολύ υγρά περιβάλλοντα, ή ακόμα και κάτω από το . These worms live in colonies, and create their own tubes from sand and zirconium oxide.

Οι επιστήμονες έχουν δείξει ενδιαφέρον για την παραγωγή κόλλας από διαφόρα είδη του ζωικού βασιλείου, όπως η κόλλα του σαλιγκαριού που παράγει για να μένει σταθερό σε διάφορες επιφάνειες για πολλά χρόνια. Αυτά τα βιολογικά υλικά, που περιλαμβάνουν επίσης και το μετάξι της αράχνης, εμφανίζουν ενδιαφέρουσες φυσικές ιδιότητες που θα μπορούσαν να έχουν σημαντικές in .

With the study of the sandcastle (scientific name: Phragmatopoma californica), scientists led by Pedro del Nido have recently made a glue that is not only biodegradable but also capable of sealing the arteries. The material has already been tested in mice, the team said.

Σε ένα έγγραφο που δημοσιεύεται στο τεύχος της 8η Ιανουαρίου του επιστημονικού περιοδικού Science Translational , η ερευνητική ομάδα του Brigham αναφέρει ότι η κόλλα είναι αρκετά ισχυρή ώστε να κρατήσει τα αιμοφόρα αγγεία και να τα σφραγίσει ακόμη και υπό τις συνθήκες υψηλής πίεσης του συστήματος του αίματος. Η σφραγιστική κόλλα είναι επίσης σε θέση να αντέξει την πίεση που προκαλείται από την ανθρώπινη καρδιά που χτυπά.

Dr. Del Nido and his team plan to use this glue to replace sutures and staples, commonly used methods to heal various incisions and wounds after surgery.

Sutures should not be removed from the medical market completely, since there are certain types of operations in which they are necessary. However, when it comes to heart surgery, the new glue may do better overall in the sealing of the arteries.

"A glue is the Holy Grail for heart surgery. At the moment we are using stitches "says the leader of the team. "Every time the needle and thread enter the normal tissue, they do a little damage. It usually does not matter. But I operate on children's hearts. "For children, this damage can really be a problem," he explains.  in the NPR.

In cardiac surgery, the use of simple skin glue is not feasible. In addition to containing potentially toxic chemical cyanoacrylates, these substances tend to harden when in contact with water. If this happened in the heart, or in a blood vessel, the consequences could be devastating to patients.

The research team, which includes the biologist engineer  Jeffrey Karp, says the glue has already completed a series of tests successfully. "We made a hole in the heart of a living rat and showed that we can seal it without removing the blood. The animals were fine after six months, explains Karp, adding that clinical trials in humans are the next step. The Best Technology Site in Greecefgns
