The risk of damages of neurological function by the operation of metastatic brain tumors was reduced considerably after introduction of neurosurgical apparatuses, such as ultrasonograph, ultrasonic surgical aspirator and laser scalpel. Of these, ultrasonograph is useful to indicate the exact location of brain tumor at real time during the operation. Ultrasonic surgical aspirator reduced the risk of damage on important brain structures due to the selectivity of fragmentation and the safety of the dissection in the vicinity of important vessels and nerve tissues. Laser scalpel is also useful to extirpate the hemorrhagic tumor with hard consistency. Cases introduced in this paper were: case 1, brain metastasis from lung cancer located just under the left motor area in brain; case 2, metastasis with abundant neovascularization from renal cancer to orbital cavity which showed invasion to orbital roof and frontal bone; case 3, radiation induced sarcoma after the treatment of retinoblastoma; case 4, a large cerebellar metastatic tumor; case 5, neurogenic sarcoma which were successfully removed by using one of or combination of ultrasonograph, ultrasonic aspirator and laser scalpel. Advantage of these new instruments for the surgery on metastatic brain tumor was mentioned here. However, it is necessarily to get a custom before we use these apparatuses at operation efficiently.
在引入超声诊断仪、超声手术吸引器和激光手术刀等神经外科器械后，转移性脑肿瘤手术导致神经功能损伤的风险大幅降低。其中，超声诊断仪有助于在手术过程中实时准确显示脑肿瘤的位置。超声手术吸引器由于其破碎的选择性以及在重要血管和神经组织附近进行解剖时的安全性，降低了对重要脑结构造成损伤的风险。激光手术刀对于切除质地坚硬的出血性肿瘤也很有用。本文介绍的病例有：病例1，肺癌脑转移瘤位于脑左侧运动区下方；病例2，肾癌转移至眼眶腔，伴有大量新生血管，侵犯眼眶顶和额骨；病例3，视网膜母细胞瘤治疗后发生的放射性肉瘤；病例4，巨大的小脑转移瘤；病例5，神经源性肉瘤，使用超声诊断仪、超声吸引器和激光手术刀中的一种或联合使用成功切除。这里提到了这些新器械用于转移性脑肿瘤手术的优势。然而，要想在手术中高效使用这些器械，有必要先熟练掌握。
