For cancer patients, surgery is an indispensable treatment, but during surgery, it is often the case that cancer cells are not removed. Recently, Australian scientists have developed a small microscope like a sewing needle. It can help doctors see the patient's cancerous tissues and remove them completely.
This microscope was originally made to assist breast cancer surgery. In breast cancer surgery, it is often the case that cancerous cells are not completely removed. And this needle microscope can help surgeons to see cancerous cells more clearly during the operation and completely remove them.
The new lensless imaging technology is believed to not only reduce the costs associated with medical care, but also provide fast and cheap medical diagnosis in areas with limited resources, and also advance telemedicine.
Two key requirements for medical care are: ease of use and durability. The use of the microscope minimizes training, and its large-field imaging feature eliminates the need for samples to be scanned or accurately aligned in the microscope; the operation is simple enough to fill the sample with the chip, and then move it to the side of the microscope In a slot on the top; because of its large aperture, it can also avoid problems caused by debris blocking the light source; in addition, because there are almost no moving parts, the microscope is quite strong; and it can also be digitally integrated as part of a telemedicine network, Become a model to fill the gap between infrastructure and mobile tools.
Robert McLaughlin, an associate professor at the University of Western Australia, said: "We hope this study can help surgeons during surgery and ensure that doctors remove all cancer cells during the surgery. This is our real goal." The surgeon Christopher Sanders said that the needle microscope image is very clear. "Under this microscope, we can clearly see where the tumor cells are, just like ultrasound images. But at the level visible by the microscope."
In Australia, about a quarter of patients who have undergone breast cancer tumor resection require a second surgery. Virginia is a breast cancer patient who has not fully recovered. She is looking forward to this microscope that can help cure her disease. "I worry about the tiny spots spreading or spreading every day. This idea troubles me every day, and I suffer very much every day. If this microscope can eliminate the possibility of a second cancer recurrence, that would be great."
The researchers said that in addition to cancer surgery, this needle microscope can also be used for the research and treatment of brain and lung diseases. Robert McLaughlin, an associate professor at the University of Western Australia, said: "With this microscope, we can understand how diseases like emphysema occur in the body. This may help scientists develop better medicines to treat this Diseases. "At present, the needle microscope is still in the experimental stage. The researchers said that if the clinical trial is successful, the microscope is expected to become popular in surgical operations within a decade.
The handheld microscope is also called a portable microscope. As the name implies, it is a small and portable miniature microscope product. It is a high-quality product developed by the perfect combination of elite optical microscope technology, advanced photoelectric conversion technology, and LCD screen technology. Technology Products.
The physical image seen by the microscope can be converted by digital-to-analog to make it image on the screen or computer of the microscope. Therefore, the inspector can study the microscopic field from the traditional ordinary binocular observation to the reproduction on the display, which improves the work efficiency. Compared with the traditional optical microscope, it can provide a perfect solution to make the inspection work on-site and efficient.
