The influence of force feedback and visual feedback in grasping tissue laparoscopicaUy
Surgical Endoscopy and Other Interventional Techniques, 2004Due to the limited force feedback provided by laparoscopic instruments, surgeons may have difficulty in applying the appropriate force on the tissue. The aim of this study was to determine the influence of force feedback and visual feedback on the exerted pinch force.A grasper with a force sensor in the jaws was developed.

Muscle-propelled force feedback
Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2013Force feedback devices resist miniaturization, because they require physical motors and mechanics. We propose mobile force feedback by eliminating motors and instead actuating the user's muscles using electrical stimulation. Without the motors, we obtain substantially smaller and more energy-efficient devices.

Force feedback for surgical simulation
Proceedings of the IEEE, 1998Surgical simulation can provide great benefits to medicine by reducing the cost and duration of training and making the process more intuitive and informative. However, a simulation system imposes stringent requirements on the human-machine interface.

Virtual cutting with force feedback
Proceedings. IEEE 1998 Virtual Reality Annual International Symposium (Cat. No.98CB36180), 2002Cutting is an essential operation for forming and designing shapes. We have implemented a virtual cutting work space, in which we can create objects of various shapes through cutting operations. An object in the work space is defined as a closed surface that consists of triangle patches.

Force feedback in limb lengthening
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010A new variable-rate distraction system using a motorized distractor driven by feedback from the distraction force was designed. The distractor was mounted on a unilateral fixator and attached to the tibiae of 6 sheep that underwent distraction osteogenesis. The sheep were divided equally into 3 groups.

In master-slave manipulators, forces encountered by the remote hand are transmitted back to the operator. At very great distances there will be a transmission delay between an operator's movement and a resulting force. Investigation was made of the effect of long delays and differences in strategy on positioning time with force feedback alone ...

SENSORY SUBSTITUTION FOR FORCE FEEDBACK IN TELEOPERATION
Presence: Teleoperators and Virtual Environments, 1992The objective of this research was to study the capabilities of sensory substitution for force feedback through the tactile and auditory senses for teleoperation tasks, with and without time delay. The motivation and potential benefits of sensory substitution for force feedback with vibrotactile and auditory displays are discussed.

Force feedback and student reasoning
Proceedings of the 2004 conference on Interaction design and children: building a community, 2004The primary purpose of this case study was to examine whether force feedback within a computer simulation had an effect on reasoning by fifth grade students about concepts of gravity, mass, force, and motion. This study used a computer-based paddleball simulation with guided inquiry as the primary stimulus.

Laparoscopic Forceps with Force Feedback
2018There are two main aspects of safety and effectiveness in laparoscopic surgery. The first is ensuring an appropriate operation field and maintaining this throughout the procedure. The second is finding the correct tissue plane and applying appropriate traction and counter-traction.
