Automated surgical instrument localization is an important technology to understand the process and in order analyze them provide meaningful guidance during surgery or index after surgeon. We introduce a new dataset that reflects kinematic characteristics of instruments for automated videos. The hSDB(hutom Surgery DataBase)-instrument consists information from 24 cases laparoscopic cholecysteco...

Laparoscopic surgery is a very active area of research in clinical medicine. Detection tools surgical videos can help physicians operate instruments, reduce complications, and ensure patient safety. However, the size laparoscopic instruments highly variable, leading to poor detection. Feature pyramid networks (FPNs) effectively solve problem multi-scale target detection, but FPNs still have som...

The assessment of surgical skills for Minimally Invasive Surgery (MIS) has traditionally been conducted with visual observation and objective scoring. This paper presents a practical framework for the detection of instrument/tissue interaction from MIS video sequences by incorporating multiple visual cues. The proposed technique investigates the characteristics of four major events involved in ...

This article introduces a new biomedical / open surgical instrument to assist surgeon in applying surgical clips to patient’s body tissue and blood vessel during surgical processes. The new clip delivery system is designed to better the clip’s distal advance through internal clip channel, jaw guiding track, and all other transition areas to keep surgical clip from accidental shooting out during...

Computer-assisted interventions (CAI) aim to increase the effectiveness, precision and repeatability of procedures to improve surgical outcomes. The presence and motion of surgical tools is a key information input for CAI surgical phase recognition algorithms. Vision-based tool detection and recognition approaches are an attractive solution and can be designed to take advantage of the powerful ...

This paper presents a robotic vision system that automatically retrieves and positions surgical instruments during robotized laparoscopic surgical operations. The instrument is mounted on the end-effector of a surgical robot which is controlled by visual servoing. The goal of the automated task is to safely bring the instrument at a desired three-dimensional location from an unknown or hidden p...

This paper presents a robotic vision system that automatically retrieves and positions surgical instruments in robotized laparoscopic surgery. The surgical instrument is mounted on the end-effector of a surgical robot which can be controlled by automatic visual feedback. The goal of the automated task is to bring the instrument at a desired location from an unknown or hidden position. To achiev...
