[ China Pharmaceutical Network Technology News ] On February 22, some media reported that Anhan Medical uses precision magnetic control technology to enable capsule endoscopes to be controlled by doctors and move freely in the human stomach. Anhan Capsule Gastroscope has changed the first-generation capsule endoscope to only check the dilemma of small bowel examination, and accurately check the stomach of the human body. In the past, some researchers used magnetic fields to simultaneously control clusters of tiny magnets. Recently, Philips researchers have mastered a new technology: under the action of a magnetic field, you can control any one of the micro-robot groups and allow them to move freely without disturbing other micro-robot activities. Doctors can use these robots to carry drugs that are accurately placed in the tumor area.
The LEGO robots use the limbs attached to the magnetic screws to show jumping and grabbing movements. Fortunately, they can move independently without affecting the surrounding robots.
A new study suggests that magnetically controlled tiny robots may one day help fight cancer in the body. In the past decade, scientists have demonstrated that they can manipulate magnetic forces to guide medical devices in the human body, and researchers can apply force to remotely control objects. For example, previous researchers used magnetic fields to manipulate catheters within the heart and direct video capsules in the intestines.
In principle, these subjects can assist in the treatment of major diseases such as cancer, but it is still a challenge to individually control a microscopic device to move it in the corresponding direction and speed as needed, because under the same magnetic field control, the magnet The movement is usually the same.
Recent research shows that scientists have developed a way to control any one of a set of magnetic devices to perform a separate behavior.
Jürgen Rahmer, Philips's innovative physicist and research leader, said: "Our technology can control magnetic robots in the human body."
In the experiment, the researchers can make several magnetic screws precisely positioned at the same time and rotate in different directions. Scientists in principle point out that they can manipulate hundreds of tiny robots simultaneously. First, the scientists made many tiny identical magnetic screws.
Next, the researchers fixed the magnetic screws with a strong, uniform magnetic field in which there was a small, thin magnetic field in which the magnetic screws were free to move, the researchers said, if they were superimposed one more With a weak rotating magnetic field, the magnetic screw can rotate freely.
“A researcher suggested using a screw drive mechanism so that the robot does not need a battery when working in the human body.†Rahmer said
One of the most likely applications of this technology is to bring the magnetic screws of this group of robots with injectable pills. Researchers say doctors can use magnetic fields to control these magnetic screws to release drugs where they are needed, accurately applying the drug to tumor sites rather than healthy tissue, thereby reducing side effects. Once the drug dose is in place, control the magnetic screw system to release the drug (pill) Will be made of metal material, otherwise there will be radiation).
Another application, Rahmer said, may be medical implants that change over time. For example, during people's recovery, the magnetic field can change the shape of the implant to better fit the patient's body.
In the future, researchers have developed new technologies to control tiny robots and use imaging techniques such as X-ray machines or ultrasound scanners to show the location of these devices in the body.
