Occlusion-robust markerless surgical instrument pose estimation.
Healthc Technol Lett
December 2024
Hamlyn Centre for Robotic Surgery, Department of Surgery and Cancer Imperial College London London UK.
The estimation of the pose of surgical instruments is important in Robot-assisted Minimally Invasive Surgery (RMIS) to assist surgical navigation and enable autonomous robotic task execution. The performance of current instrument pose estimation methods deteriorates significantly in the presence of partial tool visibility, occlusions, and changes in the surgical scene. In this work, a vision-based framework is proposed for markerless estimation of the 6DoF pose of surgical instruments.

Objective: To evaluate the learning curves (LC) and their assessment methods for Robotic Laparoscopic Surgery (RLS) and Laparoscopic Surgery (LPS) in gynaecologic procedures.
Materials And Methods: A systematic review of the literature was performed including the English language observational or interventional studies reporting the absolute number of procedures needed to achieve competency in RLS and LPS gynaecologic procedures, along with an objective and reproducible LC assessment method.
Postoperative urinary dysfunction following lateral lymph node dissection for rectal cancer via minimally invasive surgery.
BMC Surg

Department of Coloproctological Surgery, Juntendo University Faculty of Medicine, Tokyo, Japan.
Background: Lateral lymph node dissection (LLND) for locally advanced rectal cancer (LARC) is performed widely since it reduces local recurrence. However, there are some disadvantages to LLND, including technical difficulties and association with postoperative urinary dysfunction. Procedures for LARC have also become more minimally invasive: laparoscopic surgery (LS) has become more common, and use of robot-assisted LS (RALS) is increasing.

Gastroenterological Surgery, Saitama Medical University International Medical Center, Hidaka, JPN.
The Senhance robotic system (Asensus Surgical, Durham, NC, USA) is an innovative platform for minimally invasive surgery. It enables surgeons to perform precise and cost-effective procedures using reusable instruments and has advanced features such as haptic feedback and eye-tracking camera control. Herein, we present the first application of the "double bipolar method" (DBM) in a Senhance-assisted laparoscopic partial cystectomy utilizing 3 mm Maryland bipolar instruments.

Department of Surgery and Oncology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.
Background/purpose: The Japanese public health insurance system has recently covered robotic pancreaticoduodenectomy (RPD). This study aimed to review the results of RPD during the introductory period and elucidate its safety and feasibility in Japan.
Methods: Consecutive data of 425 patients who underwent RPD were retrospectively collected from 10 high-volume centers in Japan between April 2020 and September 2022.
