At about the same time in 1987, Benabid [126,127] and Seigfried [128] began implanting deep-brain stimulators into Vim of the thalamus for tremor from PD and essential tremor. Benabid’s report of his large series of Vim stimulators in 1996 [129], followed shortly thereaer by the North American series [130] brought international attention to the eld of electrical brain stimulation. e eld came full circle as a result of other important trends. e limitations and complications of levo-dopa treatment for PD began to become apparent by the 1980s, and as a result Laitinen-a student of Leksell, a leader in functional neurosurgery in the 1950s during which time pallidotomies were carried out-began to revisit ablative surgery for PD. His inuential report in 1992 of the results of pallidotomy refocused attention on the surgical treatment of PD [131]. With a large experience by then in DBS, Siegfried carried out the rst implantation of a stimulator electrode into the posteroventral internal globus pallidus for PD in 1992 [132]. e next advance resulted from new insights into the pathophysiology of PD: the report of DeLong and colleagues of the amelioration of experimental PD in nonhuman primates by the ablation of the subthalamic nucleus, whose glutamatergic driving actions on the globus pallidus internus was elucidated [133]. Benabid then targeted this novel region for deep-brain stimulation in 1993 (the subthalamic region, including white matter projections, had been the target for “subthalamotomies,” but never

Path planning is one of the key tasks of autonomous robot. There are many methods to generate trajectories covering closed areas, such as online trajectory planning for autonomous surgery (Osa et al. 2018), path planning for additive manufacturing (Jin et al. 2014) and treatment planning for tissue laser ablation (Su et al. 2015). Genetic algorithm, determining the parameters as interior points to be interpolated and forms polynomials representing trajectories, is used to search the effective optimal solution of trajectory in the task space (Tian and Collins 2004). A framework including multimodal MRI analysis (T1w, SWI, TOF-MRA) was used to determine the optimal trajectory of the DBS target in the region of subthalamic nucleus and internal globus pallidus (Bériault et al. 2011). However, there is currently no path planning method for removing mixed liquid in oral surgery.
