The surgeries are meant to leave behind scars created by the cutting and suturing thus in case of nose, face, or ears the recovery time should be completely crystal clear. The molecular surgery process that makes use of measly needles, 3D printed molds, and electric current to easily reshape the living tissue without any incisions, scars, or need for recovery time. The current method can also help repair immobile joints and substitute laser eye surgery. The noninvasive technique is cost-effective and is performed under local anesthesia that is only 5 Minutes is enough to complete the entire process. The researchers Brian Wong from the University of California and Michael Hill Occidental College have developed a noninvasive technique to reshape the cartilages.
This new technique could potentially prove positive for cosmetic surgery procedures like constructing or shaping the nose for a better appearance. It can also fix certain problems including treatment deprived conditions, deviated septum, joint contractures resulting due to cerebral palsy or strokes. The painful deviated septum surgery could now be replaced by this current project. The infrared laser usage for heating the cartilage for making it malleable without killing the tissues was hard; hence, rather using the current to reshape the tissue seemed easier. Thus, the team was trying to refine the method as much as possible in order to prevent tissue damage.
Cartilage comprises of collagen fibers bundled together using biopolymers. They also contain positive sodium ions and negatively charged proteins on the basis of their density the cartilage turns stiffer. When the current strikes through the cartilage, the water in the tissue split into hydrogen and oxygen ions or protons followed by the negative proteins being charged out by the positive ions and thereby resulting in malleable cartilage due to lower charge density. The reshaping of the tissue becomes faster and easier. In traditional methods, the cutting of the tissues and fixing of the broken pieces is followed but it leaves behind a scar tissue that has to be removed in the following surgery. Thus, molecular surgery can be opted to avoid such mechanical damage. The researchers tested it on the corneas as the shape of it is known to affect vision. The 3D printed contact lens has electrodes painted on it before being placed on the eye and following which a current was passed to soften the cornea so as to change the curvature for a better vision.
