A few Lego parts, a bucket, and water. Enjoy!

From whirlpool turbines to edible cutlery, water blobs, and package-free shampoo and toothpaste, weve compiled a list of 22 inventions that could help us cut back on plastic, reduce garbage in the sea, and make the Earth a better place.

Check out the CataractCoach channel @Uday Devgan for more!

We did a survey recently and about 20% of our viewers indicated that they wanted more videos of novice surgeons who are still learning basic techniques of cataract surgery. Todays video is a young surgeon who has only done about 30 cataract surgeries on his own and he is doing phaco stop-and-chop for nucleus removal. 

The surgery is quite good for an ophthalmologist who is so early in the learning curve of phacoemulsification, but there are a few areas that could use refinement. 

The excellent parts of the surgery are:

good draping and patient anesthesia
properly constructed incisions
excellent capsulorhexis and hydro-dissection
good ability to pivot within the incision and keep eye in primary
stop-and-chop technique is done very well
cortex removal is good and thorough
IOL is loaded well and centered in capsular bag
So much of the surgery is excellent, that we have just a few suggested areas of improvement:

since a cohesive OVD is used for the capsulorhexis, coating the corneal endothelium with dispersive OVD prior to inserting the phaco probe is recommended
allow the IOL haptics to unfold with the eye full of OVD instead of having the cold water from the I/A probe cause the lens to become less flexible
hydrate the incision in a linear manner at the corneal stroma to avoid having the two corners of the incision sealed while the central incision is not hydrated
This resident is sure to become a very talented surgeon and I look forward to operating with him over the course of the next year.

This craniectomy animation is for patient education, which shows how surgery is done to remove a part of your skull in order to relieve pressure in that area when your brain swells. A craniectomy is usually performed after a traumatic brain injury. Its also done to treat conditions that cause your brain to swell or bleed.

The S.T.A.T. tourniquet works like a zip tie. It has a built-in timer for medical professionals to track and a self-locking system that adjusts to the pressure needed. The company claims it can cease bleeding in 5-10 seconds.

Pediatric HAL is a medical robot that actually bleeds, cries, urinates and mimics other human behavior. Medical students use HAL to learn how to diagnose and treat illness before working with real patients. Pediatric HAL is part of a line of robots from a company called Gaumard. Gaumard also makes robots that simulate pregnant people, newborns, and trauma wounds.

The regions and lobes of the brain are identified along with some of the nerves and vessels. The basic functions of the cortex of each lobe are introduced along with principal sulci and gyri. The importance of the left hemisphere for language and the temporal lobe in memory are mentioned along with the concept of cortical localization. A classical frontal section is used to demonstrate gray and white matter along with the primary internal structures.

Meet The 24-Year-Old Whose Prosthetic Limbs Are Changing Lives

Braces are the most effective and comfortable way for correcting a bite. This is the only orthodontic system which allows for the movement of a tooth in any direction, including turning it axially.

In this video youll see how braces work. With the help of special glue, braces are attached to the surface of the teeth. Then orthodontists put on a special metal archwire, which is fixed with rubber bands or a special system.

The braces themselves dont correct the position of the teeth. This is done by the archwire. In order for the system to work successfully, the archwire has to be made more elastic.

The braces are glued to the teeth in the center of their crowns. Each tooth has its own «personal» brace. The principle of the system is that the archwire, in trying to return to its initial form, very slowly but surely pulls the teeth into the “right” place with the help of the braces stuck to their surface.

An orthodontist gradually makes the archwire more rigid to correct the position of the teeth. The replacement of the archwires should be done about once a month on average. In each case, depending on the type of brace system, replacing the archwires may have to be performed more or less frequently.

When braces and the arch are not enough to correct the bite, additional elements are also used: various springs of different diameters and purposes, elastic in the form of a chain, and other specific devices. All of these different elements of the braces system aim to give you a perfectly beautiful smile!
