In modern technology society, the speed of advancement of medical technology is unimaginable, and sometimes it can even subvert our inherent impression of traditional medicine. In recent years, we have seen many new implantable treatments, and developers are constantly developing a variety of new technologies to help people suffer, or just more humane. We can implant bionic lenses in the eye for better vision, electronic tattoos to detect blood sugar levels, and even in the near future, birth control via wireless devices. Let's take a look at some of the new results of implantable medical research in recent years.
The most natural bionic robot
RSLSteeper from the UK announced the launch of a BeBionic3 bionic hand that is more flexible than normal. This robot is made of carbon fiber and aluminum as the main material and is made of aluminum alloy to create a "knuckle joint". Thanks to the new materials and design, this robot can avoid the excessive weight of the previous products. The problem, although the overall weight of the manipulator is reduced, it is still "strong" to lift the heavy box, while the "finger" force is soft enough to easily pick up an egg.
BeBionic 3 is actually a myoelectric artificial hand rather than the existing common electric prosthetic hand. The myoelectric prosthesis is produced by the occultator's brain innervating the residual muscles to produce the myoelectric signal. By using the myoelectric signal family to control the micromotor and drive the transmission system, the artificial hand is driven by the human body. Liyuan upper limb prosthesis. Because the movement of the myoelectric artificial hand accepts the brain command, in addition to the strength of the electric artificial hand, it also has the advantages of strong direct sensitivity, flexible control and convenient use, and is the development direction of the modern upper limb prosthesis.
Get vision different from ordinary people
Biomimetic contact lenses developed by OcumeTIcs can permanently eliminate the distress of ordinary frames or contact lenses. Implantation of this biomimetic contact lens only takes 8 minutes of surgery. After being placed in the eye, it is rinsed with normal saline. After about 10 seconds, it will spread over the entire eyeball, and the vision can be corrected immediately. In addition, the corrected visual acuity is three times better than 1.0 (20/20). In other words, if you can only see a distance of 10 feet, you can see a distance of 30 feet when you wear bionic crystals.
In addition, the technique of this biomimetic crystal is safe and does not cause biological changes to the eye. Anyone who implants bionic crystals will not get cataracts, because human crystals will naturally age, and those who do cataract surgery are implanted with intraocular lenses. This type of surgery is safer than laser surgery because it does not cause glare or poor night vision, nor does it gradually deepen over time.
Put the heart with an automatic pacemaker jacket
Implantable pacemakers and defibrillators have saved the lives of thousands of heart patients and improved their quality of life, such as John Rogers of the University of Illinois at Urbana-Champaign and Professor Igor Efimov of the University of Washington, St. Louis. Customized jackets for the heart through 3D printing technology. This jacket has a mesh of tiny electrodes and sensors that detect heart rate abnormalities and deliver precise shocks when implanted in the heart, while patients and doctors hope to get real-time data and operations through smartphone applications.
Connected to a smartphone, it allows patients and doctors to access heart health-related data, while feature-rich sensors allow doctors to track indicators such as metabolism, body temperature, and blood pH so that they can be detected early before the patient feels Heart failure and myocardial ischemia. In addition, this smart pacemaker jacket has the great advantage that it can be customized for the user to perfectly fit the heart of each user.
Brain implant electrode
A new type of brain implant electrode developed by researchers from the University of Pennsylvania, consisting mainly of silk substrate, ultra-thin plastic layer and fine metal electrode, can closely fit the brain surface and accurately monitor brain cell activity. Help with epilepsy, spinal cord injury and other neurological diseases.
The researchers used electrodes with a diameter of 500 microns, which is equivalent to 5 hair thicknesses. They hope to develop a denser brain implant electrode to improve signal resolution. The brain implant electrode can well record the brain activity of the paralyzed patient, and then can transfer the activity record to the movement of the computer mouse pointer to help the brain injury patient control the robot arm. Because of the softness, ultra-thinness, and high sensitivity of this new implanted electrode material, it can reach areas of the brain that are not accessible to older brain implant electrodes.
For patients with epilepsy, this implanted electrode is highly sensitive and can detect seizure signals, thereby sending pulses to block abnormal discharge of neurons; for patients with spinal cord injury, the implanted electrodes can be used in the patient's brain and the traction they use, Signals are transmitted between orthopaedic appliances, acting as an "interface" for both to facilitate manipulation of the appliance.
Tattoo monitoring blood sugar
Most people with diabetes have to endure day-to-day finger sticks in order to check blood sugar. Nanotechnology now offers a cool solution: glucose tracking tattoos. This glucose-trace tattoo can monitor blood sugar levels at any time, which is obviously much more advanced than a one-shot test. More importantly, it is more in line with one of our habitual cognitions without having to endure pain often.
The principle of this technology is first of all a nanosensor that emits fluorescence when it encounters glucose, so that glucose will be visible. Then tracking the tattoo once it is implanted into the skin is actually a monitoring device, so reading the data returned by the subcutaneous sensor will be very accurate.
State of the art spinal implant
Researchers from the Federal Institute of Technology in Lausanne, Switzerland, have successfully developed a spinal implant system called e-Dura. This system reduces the risk of rejection and further injury by utilizing a flexible implant designed specifically for the patient's spinal fusion.
The e-Dura is designed to be implanted directly into the patient's brain or spinal cord, below the dura mater, and the dura mater surrounds the brain and spinal cord. It has mechanical properties such as flexibility and elasticity, and is almost identical to the human active tissue surrounding it, which greatly reduces the risk of inflammation, friction and wear. The implant is treated around a damaged site on the spine. In theory, the method allows the patient to use his limbs after treatment. It can also be used to monitor electrical impulses from the brain in real time, enabling researchers to accurately measure The patient's intention to move before the brainwave signal is converted into motion.
Wireless contraception
How to be safe and effective contraception has always been the goal that human beings have been searching for for centuries. MicroCHIPS, a technology company based in Lexington, Mass., is developing a wireless implantable remote remote control chip that turns on or off with remote remote control to help people's birth control.
The implantable wireless chip is about 20 & TImes; 20 & TImes; 7 cubic millimeters, which can be implanted into the user's arms, back, abdomen, etc. It implants a micro-contraceptive agent under the skin of the human body, which can release a trace amount of levonorgestrel into the blood night of the human, thereby allowing the user to control. Because this implantable wireless chip can automatically release the contraceptive hormone, it has a very obvious advantage compared to the traditional contraceptive. Through contraceptive birth control, users need to insist on taking it at the same time every day, so that they have a good birth control effect.
A more special aspect of the MicroCHIPS implantable wireless chip is that this method of birth control lasts longer. Unlike other commonly used implantable contraceptives, these implantable contraceptives last only 5 years after implantation in the human body, while the MicroCHIPS chip is valid for up to 16 years.
