切除脑深部肿瘤的内窥镜由内窥镜镜体、导向管、有关手术器械、光源及术中录像显示装置五部分组成。内窥镜呈枪状，长２００ｍｍ，外径１０ｍｍ，工作道最大径９．６ｍｍ；导向管有筒状和伞状两种；有关手术器械保证镜下直视取瘤和确切止血；术中屏幕显示对手术操作起到放大作用。通过内窥镜及引道作持续吸引和间断冲洗，保证术野清晰。该镜与立体定向术相结合可以准确地小创伤地切除脑深部肿瘤，其适应症是丘脑基底节肿瘤和脑室内肿瘤。
The endoscope for resection of deep brain tumors consists of an endoscopic scope, a guide tube, related surgical instruments, a light source, and an intraoperative video display device. Endoscopic gun-shaped, length 200mm, outside diameter 10mm, working path maximum diameter 9.6mm; guide tube with cylindrical and umbrella two kinds; related surgical instruments to ensure straight under the microscope to take the tumor and the exact hemostasis; intraoperative screen The display is amplifying the surgical operation. Through continuous suction and intermittent irrigation through the endoscope and guideway to ensure clear surgical field. The combined use of this mirror and stereotactic techniques allows the accurate ablation of deep brain tumors with minimal trauma. The indications are thalamic basal ganglia and intraventricular tumors.
