“…International organizations such as the American Society for Testing and Materials (ASTM) and other international organizations are making efforts to standardize medical robotics accuracy assessment (Howe & Matsuoka 1999; Zoppi & Khan 2010; Stiehl et al 2007; Haidegger et al 2010; Kroneif et al 2012). Yet, there are no widely accepted methods or regulations.…”

Thousands of operations are annually guided with computer assisted surgery (CAS) technologies. As the use of these devices is rapidly increasing, the reliability of the devices becomes ever more critical. The problem of accuracy assessment of the devices has thus become relevant. During the past five years, over 200 hazardous situations have been documented in the MAUDE database during operations using these devices in the field of neurosurgery alone. Had the accuracy of these devices been periodically assessed pre-operatively, many of them might have been prevented.The technical accuracy of a commercial navigator enabling the use of both optical (OTS) and electromagnetic (EMTS) tracking systems was assessed in the hospital setting using accuracy assessment tools and methods developed by the authors of this paper. The technical accuracy was obtained by comparing the positions of the navigated tool tip with the phantom accuracy assessment points. Each assessment contained a total of 51 points and a region of surgical interest (ROSI) volume of 120x120x100 mm roughly mimicking the size of the human head.The error analysis provided a comprehensive understanding of the trend of accuracy of the surgical navigator modalities. This study showed that the technical accuracies of OTS and EMTS over the pre-determined ROSI were nearly equal. However, the placement of the particular modality hardware needs to be optimized for the surgical procedure. New applications of EMTS, which does not require rigid immobilization of the surgical area, are suggested.

“…Traditional stereotactic surgery generally utilizes one head frame to implement positioning, which can cause pain and fear in patients; for uncooperative patients, the operations can be more cumbersome and difficult. In addition, surgical operations can be affected by the occlusion of the frame . The Remebot navigation and positioning system used in this study consists of one hexa‐degree‐free arm, one master computer, and one binocular camera, which does not require the use of the positioning frame; therefore, the operator can perform a precise operation and approach design assisted by the real‐time camera positioning.…”

Objective To verify the minimally invasive surgical approach and therapeutic effects of using the medical neurosurgery robot Remebot to treat hypertensive intracerebral hemorrhage (HICH). Methods Clinical data for 17 HICH patients were analyzed retrospectively. Hematoma evacuation and tube drainage using Remebot frameless stereotaxic techniques were performed for all patients, and urokinase was injected into the hematomas after the operations. Results Robot‐assisted stereotactic techniques can accurately guide hematoma punctures, and no deaths occurred among these patients. The average positioning error was 1.28 ± 0.49 mm. The average drainage duration was 3.4 days. The 3‐month postoperative follow‐up revealed improved neurological functions and quality of life for all patients. Conclusions The medical neurosurgery robot Remebot is minimally invasive, has high positional accuracy, and facilitates surgical planning according to the shape of the hematoma. Therefore, robot‐assisted surgery using Remebot represents a safe and effective treatment method for hematoma evacuation and tube drainage in HICH patients.

The work tool of the robot consists of a mechanical interface (4), which makes it possible to connect the holder of the optical waveguide (5) to the flange surface of the robot (6). To be able to perform measurements, a reflector (7) of the laser tracker must be installed on the mechanical interface.…”

In this article, in order to justify the expediency of using a robot in maxillofacial operations with a diode laser, four basic criteria for comparing typical trajectories are presented, which allow quantifying the program movements of the robot and the manual movements of the surgeon. The presented comparison criteria are in part based on the ISO 9283. An experimental setup has been developed for the research, in which the medical instrument is moved using the robot KUKA LWR 4+. The robot's movements are measured using a coordinate measuring machine, a laser tracker. Along with the measurements of the program movements of the robot, the manual movements of the surgeon are also measured. 
