Percutaneous therapy is a common clinical operation in minimally invasive surgery. Yet, learning curve of this skillful manual operation is steep, which imposes negative impacts on its further advances. In this paper, we proposed a novel workflow to simulate percutaneous therapy through visuo-haptic rendering based on the clinical trials. Intraoperative puncture data, obtained by our 6DOF force recording...
Percutaneous surgery is a typical minimally invasive surgery. Featuring minimization in trauma and infection rate as well as rapid recovery time to patients, percutaneous therapy has replaced various traditional open surgery approaches and has become an essential approach for a series of clinic operations over the past decades. However, the practice and training for such a vocational manual skill...
Immersion is of paramount importance for virtual training tasks, especially in the area of medical training simulations. Although hap tic interaction has been the major boost for immersion in visuo-hap tic rendering, the way how visual rendering represent detailed information can greatly affect hap tic pipeline and therefore is also crucial for an engaging and effective training simulation. In this...
This paper addresses a major challenge in data-driven haptic modeling of deformable objects. Data-driven modeling is done for specific objects and is difficult to generalize for nearly isometric objects that have similarities in semantics or topology. This limitation prevents the wide use of the data-driven modeling techniques when compared with parametric methods such as finite element methods. The...
Training of optometrists is traditionally achieved under close supervision of peers and superiors. With the rapid advancement in technology, medical procedures are performed more efficiently and effectively, resulting in faster recovery times and less trauma to the patient. However, application of this technology has made it difficult to effectively demonstrate and teach these manual skills as the...
The ability for a bio-operator to utilise a haptic device to manipulate a microrobot for intracellular injection offers immense benefits. One significant benefit is for the bio-operator to receive haptic guidance while performing the injection process. In order to address this, this paper investigates the use of haptic virtual fixtures for cell injection and proposes a novel force field virtual fixture...
