The world of surgeons: a precise world under surgical microscopes

The shadowless light came on, and my fingers lightly touched the control panel. The beam of the surgical microscope accurately landed on the surgical area. As the chief surgeon, this is the battlefield I am most familiar with - the intricate world of optics and anatomy intertwined. In the complex reconstruction surgery of urology, this surgical microscope for urology has become an indispensable partner. Its LED light source direct for surgical microscope projects cool white light, without infrared or ultraviolet radiation, which not only avoids tissue thermal damage, but also allows the fine blood vessels of the ureteral mucosa to spread out clearly like a map.

Ear surgery also benefits from the innovation of microscopic techniques. When performing tympanoplasty, I switched to the ent surgical microscope mode, which features a long working distance objective lens with ent function that opens up the narrow external auditory canal. The assistant synchronously observes the repair process of the middle ear ossicular chain through a microscope surgical camera, doubling the efficiency of teaching and collaboration. The sterile coverage for surgical microscope at the joint of the microscope is ingeniously designed to maintain the integrity of the sterile barrier even in the event of accidental contact with the surgical field, giving the team peace of mind.

The demanding precision of ophthalmic surgery has pushed microscopy techniques to the extreme. When performing phacoemulsification of cataracts under ophthalmic surgical microscope, stable red reflex surgical microscope function becomes crucial. Four independent coaxial light paths penetrate the pupil, forming a uniform red light reflection on the retina, making the lens capsule clear and distinguishable like a glass shrouded in morning mist. The unique illumination system of this ophthalmology surgical microscope significantly reduces the risk of capsulotomy, especially when dealing with overripe cataracts, where the cloudy lens no longer hinders the identification of key structures.

Neurosurgery has entered the three-dimensional era. The neurological surgical microscope is equipped with a 3D surgical microscope system that completely changes the experience of deep tumor resection. When I was dealing with a right frontal lobe glioma, the stereoscopic image in the eyepiece made the tumor boundary distinct from the layers of normal brain tissue. The foot pedal control activates the robot assistance function, and the camera automatically tracks the tip of the instrument deep into the lateral fissure pool, while my gaze never leaves the 4K image presented by the neural surgical microscope. This immersive experience was just a science fiction scene ten years ago.

Of course, the popularization of precision instruments still faces challenges. Grassroots hospitals often inquire about the price of surgical microscopes, with a particular focus on the reasonableness of the price. But when I operated this surgical microscope for eye surgery to complete a penetrating keratoplasty, the 0.5% improvement in the patient's vision after surgery made everyone realize that the value created by the ophthalmic surgical microscope is far beyond money. As minimally invasive concepts sweep across the field of surgery, from urology to otolaryngology, these microscopic surgical systems are redefining the boundaries of precision.

After staring at the microscopic world under the shadowless lamp for twenty years, I am still moved by the new discoveries I make every time I focus. When the beam of light from the eye surgical microscope penetrates the turbid medium, and when the robotic arm of the surgical microscope lightly turns towards the deep surgical field, what I see is not only the intricacy of tissue structure, but also the infinite possibilities opened up by technology for life - that beam of light ultimately illuminates the path of medicine towards the future.
