      • Development and Assessment of Real-Time Visual Recognition System for Scrub Nurse Robot

        Kentarou Ohnuma,Fujio Miyawaki,Teruyoshi Sadahiro,Kitaro Yoshiitsu,Ken Masamune,Yasuhiro Fukui 한국과학기술원 인간친화 복지 로봇 시스템 연구센터 2007 International Journal of Assistive Robotics and Me Vol.8 No.4

          We have been developing the Scrub Nurse Robot (SNR) for endoscopic and laparoscopic surgery. The aim of this study was to develop a real-time visual recognition system (RTVRS) in order for the second version of SNR to be capable of recognizing surgeon"s actions during exchange of surgical instruments.<BR>  The RTVRS consisted of 4 digital video cameras, a commercially-available 3D position tracking system (QuickMag Ⅳ), and two PCs. One PC had an action-recognizing algorithm and a timed-automata-based model of surgeon"s actions, both of which we had developed. The other PC had a motion controller of SNR. The algorithm can recognize the surgeon"s actions in real time from the physical movements of the surgeon with three differently-colored makers each on his right wrist, right elbow and the center of his chest. The time series positional data of those markers were obtained in real time with QuickMag Ⅳ. When the action-recognizing algorithm in RTVRS detects the moment that the surgeon starts drawing a surgical instrument after use from the operative field, a signal is produced and sent to the motion controller of SNR. Then it drives SNR to hold out its hand with an instrument needed next toward the surgeon.<BR>  We tested if the RTVRS worked properly in a laboratory, and also analyzed how a real surgeon and human scrub nurses behaved in clinical cases. As a result, we confirmed that the RTVRS-driven SNR was capable of giving a surgeon"s stand-in a surgical instrument with satisfactory timing (without making him wait for the instrument) by recognizing his two key actions during exchange of instruments: drawing a surgical instrument from and inserting another into the operative field. However, if the current SNR is used in the clinical cases where a surgical tray is used instead of the tool changer, a counterpart in the SNR system, the SNR will make real surgeons wait slightly longer than the human scrub nurses. Therefore, in order to achieve the clinical use of the SNR, design and mechanism of the device to return and store surgical instruments should be investigated and also the data processing rather than the machine movement in the RTVRS-driven SNR needs to be sped up.

        한국어판 소독간호사의 수술 중 비기술적 술기 평가도구의 타당성

        Background : This is a methodological study for validation of the Korean version of scrub practitioners’ list of intra-operative nontechnical skills system, K-SPLINTS. Method : Data were collected from multidisciplinary expert panel (n=6) and a group of scrub nurses (n=40) with minimum two years of operative theatre experience in two university hospitals in Seoul. Contents validity was calculated from expert panel and reliability, completeness, observability and usability were analyzed from scrub nurses group. Result : K-SPLINTS is deemed to be adequate for assessing and training scrub nurses’ intraoperative behaviours. Conclusion : K-SPLINTS could be useful to inspire scrub nurses non-technical skills in the operating theatre.

        종합병원의 수술복 이너웨어 디자인 개발에 관한 연구

        정삼호(Sham Ho Chung),이선화(Sun Hwa Lee),문선정(Sun Jung Moon) 한국복식학회 2011 服飾 Vol.61 No.5

        In South Korea, hospital clothes for medical staff, which require high performance and functionality, are still regarded just as uniforms. Few researches have been made into the underwear for operating room staff, which is intended to protect medical staff against possible risks happening during an operation and allow them to do their job in an easy and comfortable manner. In order to present a new design of underwear for operating room staff at general hospitals in South Korea, an investigation was made into medical staff`s preference for overseas brand samples, and it was found that they preferred to wear such clothes as are blue-colored, of a V-neck line, of a box style and has good absorptiveness and breathability. After developing the primary prototype and the conventional underwear for operating room staff at Hospital A, their appearances were evaluated, and it was found that the primary prototype was more favorably evaluated. After developing the secondary prototype, their preference for the colors and shapes was surveyed, and it was found that they preferred to wear No.6 blue colors and T/C materials. In conclusion, it is considered that a systematic research need be conducted into the designs of various hospital clothes, whose roles and functions are subdivided, including the underwear for operating room staff developed in this research.
