Background
Orthopaedic training programs are incorporating arthroscopic simulations into their residency curricula. There is a need for a physical shoulder simulator that accommodates lateral decubitus and beach chair positions, has realistic anatomy, allows for an objective measure of performance and provides feedback to trainees.
Methods
A physical shoulder simulator was developed for training...
Background
Few studies compare the effectiveness of blocked vs random practice conditions in minimally invasive surgery training, and none have evaluated these in robotic surgery training.
Methods
The dV‐Trainer® and the da Vinci® Surgical System (dVSS) were used to compare practice conditions. Forty‐two participants were randomized into blocked and random practice groups. Each participant performed...
Although the inability to feel tool-tissue interaction forces during minimally invasive surgery (MIS) has been recognized as a significant difficulty encountered by surgeons during these procedures, existing sensorized technologies have not yet been approved for use in humans. The challenges of properly cleaning and sterilizing these instruments prevent them from being operating-room ready. The focus...
In spite of the remarkable benefits that minimally invasive surgery provides for patients, the absence of force feedback is still a significant disadvantage. Several studies have been performed to address this issue; however, an accurate sterilizable force sensing technology for measuring axial and grasping forces is still missing. In this work, an innovative partial grasper has been designed and...
Skills performance assessment in physical therapy is mainly evaluated by observational means from an expert. Recent advancements in technology enable the creation of smart instrumentation that can aid trainees and evaluators during the learning and evaluation process. Towards this goal, this paper presents the design and development of a sensorized glove for measuring movement and interaction forces...
Minimally invasive surgery prevents surgeons from manually palpating organs to locate subsurface tumors and other structures. One solution is to use ultrasound; however, it is not always reliable. Various minimally invasive surgery instruments that provide tactile feedback have been proposed to augment ultrasound sensing for tumor localization; however, current designs have limitations such as cumbersome...
This paper introduces a novel ultra thin strain sensor made of superelastic nitinol wire that is well suited for force sensing applications of surgical instruments. The sensing principle used for the described sensor is the same as that for conventional strain gauges; however, the proposed sensor has significant advantages of thinner size (15 μm diameter), higher gauge factor (3.5), large strain measurement...
Tumor localization in traditional lung resection surgery requires manual palpation of the deflated lung through a thoracotomy. It is a painful procedure that is not suitable for many patients. Therefore, a multisensory mechatronic device was designed to localize tumors using a minimally invasive approach. The device is sensorized with tactile, ultrasound and position sensors in order to obtain multimodal...
Although some technologies have been developed to measure tool-tissue interaction forces during minimally invasive surgery (MIS), none of these technologies have been approved for use in humans. The primary factor preventing the use of sensorized instruments in humans is their inability to withstand the stringent conditions present during cleaning and sterilization. This paper presents a series of...
Minimally-invasive surgery has revolutionized many medical procedures; however, it also impedes the ability to feel the interaction between the surgical tool and the anatomical part being operated on. In order to address this problem, it is necessary to obtain accurate measurements of the interaction forces exerted on the surgical tools during surgery. These forces can then be manifested to the surgeon...
Many challenges exist when teaching and learning arthroscopic surgery, carrying a high risk of damaging the joint during the learning process. To minimize risk, the use of arthroscopy simulators allows trainees to learn basic skills in a risk-free environment before entering the operating room. A high-fidelity physical knee arthroscopy simulator is proposed to bridge the gap between surgeons and residents...
The limitations of minimally invasive surgery include the inability to sense forces exerted by the instruments on tissue and the limited visual cues available through the endoscope. A modular laparoscopic instrument capable of measuring force and position has been designed to address these limitations. Novel image-based position tracking software has been developed and integrated within a graphical...
