Creative new medical device in 2009

Although the shadow of the recession brought about by the international financial crisis in 2009 has shrouded many countries, the impact on the global medical device market is relatively small. What's more exciting is that in 2009, Western medical device manufacturers developed a large number of innovative medical device new products. The following are some of the featured products and their performance characteristics, which are worthy of reference and reference in the industry when developing new products.

Spring-loaded prosthesis

　　 The United States is the world's largest "car kingdom." According to reports, tens of thousands of people are amputated every year in the United States due to a car accident. This also promoted the development of the US prosthetic industry.

In the past, the prostheses sold on the market were mostly “fixed prostheses”. They can only be placed on the thighs and are relatively stiff, and walking with such prostheses is inconvenient. Researchers at Arizona State University have developed a bionic prosthesis last year with joints on the ankle bones that can move freely under computer control. More importantly, the bionic prosthesis has an artificial tendon, and a spring device is installed in front of the foot to facilitate frictional resistance during walking. There is a small high-energy battery inside the prosthesis. After the disabled person puts on the new type of bionic prosthesis called "SPARKY", he can walk freely under the guidance of a doctor for a short time. According to the manufacturer, the user can drive the car after putting on the bionic prosthesis.

2. The world's first ultrasound endoscope

Ultrasound diagnostics that have been available in the past can only be used outside the body, and cannot be checked inside the organ. Olphus Instruments, a long-established medical device company, developed the world's first ultrasound endoscope last year.

This product combines a conventional endoscope with an ultrasound instrument. According to the manufacturer, the new type of diagnostic instrument is characterized in that the protruding portion of the endoscope has an ultrasonic conducting head, and the ultrasonic wave emitted by the endoscope can generate echoes in the human body channel and return to the instrument display through the optical fiber of the endoscope. On the screen, so that the doctor can judge the condition.

Ultrasound endoscopy can be used to detect small tumors in the digestive tract (this is a tumor disease that is difficult to detect using an endoscope such as a common esophagoscope), and it is helpful for early prevention and treatment of common digestive tract tumors such as esophageal cancer, cardiac cancer, pyloric cancer and gastric cancer. . Another important use is to examine the incidence of lung and respiratory tumors. Therefore, its advent provides doctors with a more advanced practical tool for early detection of respiratory/gastrointestinal diseases.

3. Magnetic particle imager

　　 Philips, a world-renowned medical device manufacturer, developed a new three-dimensional in vitro diagnostic imager, the Magnetic Particle Imager (MPI), last year.

According to the manufacturer, when using the instrument, the doctor first injects a new type of contrast agent called "nano-iron oxide" into the patient to be examined. This nano-iron oxide contrast agent will flow rapidly throughout the body. The doctor then used MPI to examine the patient. The instrument is best used to check the degree of atherosclerosis and myocardial ischemia in patients. Because iron particles can be distributed to the largest extent on lipid plaques. Conducive to MPI, doctors can observe the thickness, distribution and vascular stenosis of lipid plaque inside the patient's blood vessels, which can help early prevention and treatment of diseases such as myocardial infarction or stroke.

The MPI structure is small, and the price is lower than that of an existing electronic diagnostic imager such as CT or MRI, and the captured image is abnormally clear.

4. Prostate cancer HIFU treatment instrument

　　 The treatment of prostate cancer is more difficult. This is because the prostate gland is covered with an extremely tough outer shell (lipid membrane). It is difficult for ordinary chemotherapy drugs to enter the prostate gland through this lipid membrane. The US International HIFU Corporation, a company specializing in the development of ultrasound instruments, developed a revolutionary prostate cancer treatment device, the Sonablate 500, last year.

According to the manufacturer, the instrument uses high-frequency focused ultrasound (HIFU) to kill cancer cells. Last year, the State University of New York used the instrument to successfully treat 1,600 prostate cancer patients. Among them, more than 90% of patients have a smaller prostate cancer volume. This indicates that the product does have a role in the treatment of prostate cancer. The Sonablate 500 is expected to be available within two years. This product is expected to become a new surgical weapon for oncologists to deal with prostate cancer.

5. Hemostatic film

　　 HemCon Medical Technologies of the United States developed a new hemostatic film (trade name HemConPatch) last year. Applying it to the wound can help stop bleeding.

This new hemostatic film releases a hemostatic fluid once it encounters blood, which can be used for bleeding, surgery, or other causes of bleeding. Not only can it stop bleeding quickly, it also has the effect of resisting the infection of various microorganisms (including common methicillin-resistant Staphylococcus aureus, Enterococcus faecalis, Acinetobacter baumannii, etc.), which helps prevent cross-infection.
