CNCompared to traditional craniotomy, transsphenoidal endoscopic surgery has become an important surgical method for treating sellar tumors due to its advantages of minimal trauma, rapid recovery, and high precision. However, in neurosurgical transsphenoidal surgery, the space behind the sphenoid bone is extremely narrow, and traditional instruments can easily limit the field of vision. Hikimaging’s 4mm optical endoscope, with its superior imaging capabilities, provides crucial assistance to this surgery.
In the footage, the 4mm endoscope performs well within the narrow retrosphenoid cavity, with a clear color contrast between the tumor and normal pituitary tissue. The tiny nodules of the adenoma and the capsular vessels are clearly visible. The surgeon precisely dissects the tumor under the endoscope, avoiding damage to the optic nerve and pituitary function, demonstrating the feasibility of “millimeter-level” manipulation.
When the endoscope penetrates deep into the tunnel-like structure of the skull base, the image remains stable and distortion-free. Cerebrospinal fluid is transparent, and the dense network of small blood vessels is clearly visible, even allowing observation of vascular pulsation. This effect is crucial for avoiding vascular damage and preventing cerebrospinal fluid leakage.
Hikimaging’s 4mm endoscope, with its “small size, large field of view,” has become the “eye” of transsphenoidal adenomectomy, driving minimally invasive neurosurgery towards greater precision and safety. With the further integration of optical technology and intelligent navigation, future endoscopic surgery is expected to achieve even higher levels of precision and intelligence.
