Since developing a surgical robot, engineers across the globe have been pushing the limits of machines in medicine. This Chinese dental robot can perform implant surgery without any human assistance.
The implants were fitted to within a margin of error of 0.2-0.3mm, reaching the required standard for this kind of operation.
The robot addresses the shortage of dental technicians as well as frequent surgical errors. China imports roughly 1 million implants annually, which hardly satisfies the 400 million patients needing new teeth. The Fourth Military Medical University’s hospital takes care of 3D printing dentures.
[Dental staff] programmed the robot to move into the correct position to carry out the operation, and determined the movements, angle and depth needed to fit the new teeth inside a cavity in the patient’s mouth.
The robot adjusts to patients’ movement, which is definitely a plus. It also makes the experience a lot less intimidating, knowing your gums won’t be in for a prickly surprise. It seems surgeons are in for some serious competition.
Major cities like Vancouver may have banned the sale of puppy mill animals in pet stores, but other issues are still neglected. Pet owners are over-vaccinating their animals and, even worse, abandoning them. To combat animal cruelty, the city of Denver has stepped up to the plate and banned the declawing of cats.
“We don’t even call it declawing anymore,” Dr. Enid Stiles, a veterinarian from a Montreal suburb, said. “We have decided to call it partial digit amputation. It’s like you’re removing their knuckles,”
Denver is the first city to join another eight in California that have supported the ban. However, while the procedure is unnecessary, it remains entirely legal in Canada. Fortunately, few vets are willing to perform the surgery.
“I have a distinct impression that for new veterinarians, coming right out of schools, more will not want to perform the procedure,” she said. Some veterinary schools have even stopped teaching the procedure, Stiles added.
Cats may be chronic scratchers, but the behavior is nothing out of the ordinary. Purchasing a scratching post will save you the cost of surgery, and spare your cat from a lifetime of pain.
A few months ago, Oxford student Vanessa Restrepo-Schild patented the world’s first synthetic retina. Researchers from the University of Washington then added fish eyes into the mix, to help cure blindness. Now, the most recent success for the vision-impaired is a bionic eye, which helped a blind mother to see for the first time in years.
The device consists of a camera that is attached to glasses and connected to a chip grafted onto the retina of the eye.
The images captured by the camera are converted into a series of electrical pulses that are transmitted to the chip.
The prosthesis, Argus II, doesn’t fully restore vision, but restores something far more important — the ability to perform everyday tasks.
“Without my Argus, I see nothing. With him, I see, yes, in a different way, but it gives me a lot of hope,” [said patient Sandra Cassell]
It’s not a complete cure, but Argus II is an easy fix and one that will certainly change lives.
