Abstract Three-dimensional force perception is critically important in the enhancement of human force perception to minimize brain injuries resulting from excessive forces applied by surgical instruments in robot-assisted brain tumor resection. And surgeons are not responsive enough to interpret tool-tissue interaction forces. In previous studies, various force measurement techniques have been published. In neurosurgical scenarios, there are still some drawbacks to these presented approaches to forces perception. Because of the narrow, and slim configuration of bipolar forceps, three-dimensional contact forces on forceps tips is not easy to be traced in real-time. Five fundamental acts of handling bipolar forceps are poking, opposing, pressing, opening, and closing. The first three acts independently correspond to the axial force of z, x, y. So, in this paper, typical interactions between bipolar forceps and brain tissues have been analyzed. A three-dimensional force perception technique to collect force data on bipolar forceps tips by installing three Fiber Bragg Grating Sensors (FBGs) on each prong of bipolar forceps in real-time is proposed. Experiments using a tele-neurosurgical robot were performed on an in-vitro pig brain. In the experiments, three-dimensional forces were tracked in real-time. It is possible to experience forces at a minimum of 0.01 N. The three-dimensional force perception range is 0-4 N. The calibrating resolution on x, y, and z, is 0.01, 0.03, 0.1 N, separately. According to our observation, the measurement accuracy precision is over 95%.

Abstract INTRODUCTION We reviewed our practice at the University of Kentucky in order to assess the safety of admitting adult and pediatric patients to floor beds after craniotomy, exclusively for intra-axial brain tumor resection. METHODS Retrospective chart review of patients, adults and pediatric, who underwent craniotomy by a single surgeon (TP) for intra axial brain tumor resection between January 2012 and December 2015. 413 patient charts were reviewed, 16 were omitted due to incomplete records. RESULTS >421 craniotomies for intra axial brain tumor resection were performed. 397 patients underwent surgery, 35 of whom were <18 years of age.188 females and 209 males. 351 patients (331 adults, 20 pediatric) were admitted to floor beds. In this group, length of operation was <4 hours in 346 patients (99.1%) and >4 hours in only 5 patients (0.9%). 3 patients (0.8%) required transfer to ICU within 24 hours of floor admission. 55 adult patients required ICU stay for various reasons: 9 patients had pre-operative or intra operative EVD placement; 15 patients required prolonged ventilation; 1 patient had to be taken back to the operating room for hemorrhage evacuation; 5 had intraventricular tumors and were planned ICU admissions; 26 patients were admitted pre-operatively to an ICU bed on a non neurosurgical service and were returning to their assigned beds. In the pediatric population, 15 patients required ICU stay: 8 were for EVD management and 7 for prolonged operation or frequent neurological evaluations. In this group, the length of operation was <4 hours in 40 patients(57.1%) and >4 hours in 30 patients (42.9%). CONCLUSION Admitting adult and pediatric patients to floor beds after craniotomy for intra-axial brain tumor resection is safe. There are some conditions that mandate ICU admission: these include prolonged mechanical ventilation and the presence of an external ventricular drain.
