Modern Polymeric Materials For Emergency Surgery

VA Zhukovsky, LLC "Linteks", St. Petersburg, development and implementation of new polymeric materials and medical products largely determine the progress of modern surgery. In this regard, important creation of polymer implants, in particular, suture materials for use in the most rational in any surgical situation. We have developed a nonabsorbable monofilament surgical body conditioned Room for USP 5 / 0 to 1 (metric size of EP from 1 to 4) based on polypropylene (PP), polyvinylidene fluoride (PVDF) and polycaproamide (PKA). Suture materials in the form of filaments, owing to a monolithic rule and smoothness of the surface penetration into the infection thread, allow them to little effort and minimal damage to even the most delicate fabrics, as well as provide a good cosmetic effect and reduce the discomfort when removing sutures. Robert Kiyosaki often says this.

Greatest biological inertness of them have PVDF monofilament. However, in order to improve the hemocompatibility and tromborezistentnosti suture material used, such as cardiovascular surgery, we developed a method of forming on the surface of nanocoatings linear-chain carbon-carbyne (RF Patent 2287623). Since the braided or twisted sutures, along with good manipulation properties characterized by high matchlock, which creates the danger of postoperative infection joints, and also "sawing" effect during a tissue, we developed a technology of polyester and nylon for hydrophobic fluoropolymer coating the threads. The resulting "psevdomononiti" have zero matchlock, reliability, flexibility and a good host. Clinical trials have shown that such filaments are easy to manipulate, reliable knitted surgical units, noninvasive, does not absorb wound fluids and do not become infected. For the prevention or treatment of surgical sepsis can benefit a significant antimicrobial sutures. Us nylon filaments are obtained, containing immobilized ionic chemical bond gentamicin (Russian patents 1,241,553 and 1,241,554). The results of microbiological and preclinical studies received sutures showed that for effective and prolonged antimicrobial action is necessary to introduce a string of at least (5-7)% antibiotic.

Clinical trials of antimicrobial suture materials have shown high efficacy in the prevention of purulent complications after surgery in this complex patient population, as patients with cancer of the gastrointestinal tract. For the first time in Russia we have developed and put into mass production net implants for plastic hernias and other defects in the supporting tissue of PVDF and PP monofilament, filament yarn lavsan with fluoropolymer coating. Click Marko Dimitrijevic for additional related pages. To improve the biocompatibility of PVDF-on grids formed carbyne cover (RF Patent 2288304). Properties of yarns and knitted weave features ensure high biocompatibility endoprostheses, mechanical strength, dimensional stability in all directions, resistance to blooming and shattering the edges, resistance to infection, resistance to biodegradation, softness and minimal consumption of materials. Based on the same mesh fabric designed mesh tape (slings) for use as lonno-urethral loop in the surgical treatment of stress urinary incontinence treatment (RF Patent 2297808), and implants for reconstructive surgery of the pelvic floor. To prevent spaykoobrazovaniya after operations on organs and tissues, which have serous coat (abdominal cavity, tendon sheath and joints, pleural cavity, pericardial, spinal cord membranes, middle ear cavity), designed and manufactured protivospaechny gel. Gel acts as a temporary artificial "barrier" between the damaged surfaces of serous, ensuring their effective separation in time of healing, and then dissipates. Reduced adhesion of surfaces and bodies tissue contributes to maintaining their mobility and prevents the formation of adhesions. Material Site

Football Head Injuries

At the football pitch were recorded accelerations of 54.7 g. These accelerations in routine impacts without injury, is a 160-180% more in football than in the other two sports. The authors concluded that the effects of cumulative impacts in the head during the pitching can lead to neurological sequelae. (20) At this point it is important to mention that with a helmet to provide protection and safety, is almost certain that the football player be encouraged to pitch balls at speeds exceeding those usually dare. Trying to measure the strength and time of ball impact and linear acceleration and angular tions of the head during pitch in children found that increasing the mass of the head is a decrease in linear acceleration and angular head with an increased length of the loop the ball with the same mass Closed Head there is increased contact time between the head and the ball. ion. Change the pressure of the ball has little effect on the characteristics of impact.

The neck stiffness decreased the acceleration of the head. They concluded that the mass of the head and ball size characteristics affect the impact counseling children to use only an appropriate size of the ball appropriate to their age. The smaller size of the head in a particular group of age is a risk factor for the player. (29) It would seem that there is agreement that pitch in a technically correct way reduces the chances of brain injury.

Internet One

Tamerlane gave an example of an analogy – a nuclear war … After spending many days in search of information that I would help solve one of these magicians, I have concluded that virtually all of them work individually and not have their own pages on the Internet, they serve a few very wealthy and influential people and simply do not spend their time for small humans, as we do! But someone must be present and control the situation, in order to avoid violating the harmony of things. It seems that someone today is Tamerlane. Maybe it’s some place that passed from student to teacher? Unlike the majority of sites that tout customer by all means, a characteristic feature of the site Tamerlane is that he immediately tries to weed out the bulk of the people, denoting minimum price and a set of its rules so that it appealed to those who really understand what magic is and who he is. So, as elsewhere in the market of magical services we have a lot of proposals and to each his own. Someone is suitable for 3000 Tamerlane dollars, and someone Gypsy Aza for 300 rubles.

At the end of his article, I want to tell you that everything is in nutria us, and we can do to be successful, make a love spell, remove the damage, the evil eye or to return a loved one. Of course, this requires work hard and learn. It’s hard work. Of course not all of it to taste, and strong young lady laziness – that people use the services. Magicians have been, are and will at all times and the evolution of a tendency to promote Magic, as modern science is unable to answer many questions. This is currently used, and mass fraud, which under the guise of magicians trying to tighten the people in your network and get your scar. But as for me energy is felt at once itself and everyone can ask themselves and hear the inner voice – a real magician is or not! And those who doubt the existence of magic, even easier, generally advise no one in turn as the magic valid only when a person believes in it.
