Haptic rendering of tissue cutting with scissors.
Current surgical simulations that involve cutting with scissors lack display of forces "between the fingers" of the operator. The objective of this work is to develop a fast, realistic haptic rendering technique for scissor cutting that can be easily integrated into soft tissue models commonly used in surgical simulators. A virtual environment was created for combined graphic and haptic display...
متن کاملThe haptic scissors: cutting in virtual environments
The “Haptic Scissors” is a device that creates the sensation of cutting in virtual environments. The scissors have two degrees of freedom of motion and force feedback, one for cutting (single blade rotation) and one for translation. An algorithm was developed to simultaneously display translational and cutting forces for a realistic cutting simulation. In previous work, we used filtered data fr...
متن کاملAnalytical Model of the Cutting Process with Scissors-robot for Haptic Simulation
In this paper, an analytical model for cutting process of a plate of material with a pair of scissors is presented. The cutting model predicts that, during task, force/torque responses of the scissors depend on the toughness and geometry of the plate. A force/position control law for a pair of scissors in contact with a partially known environment is proposed. The environment is a rigid plate o...
متن کاملInteractive Segmentation with Intelligent Scissors
We present a new, interactive tool called Intelligent Scissors which we use for image segmentation. Fully automated segmentation is an unsolved problem, while manual tracing is inaccurate and laboriously unacceptable. However, Intelligent Scissors allow objects within digital images to be extracted quickly and accurately using simple gesture motions with a mouse. When the gestured mouse positio...
متن کاملCutting classes without scissors: conceptual primitives as a cognitive mechanism for idiom processing
What does it tell us about the conceptual structures underlying language use that a language can use ”prick the law” but not ”sing the law” to mean ”break the law”? Some theorists have speculated about the existence of conceptual primitives, which permeate the meaning of all words in any language (Schank, 1975, Mandler, 2004). If this premise is correct, then these concepts could also be used t...
