Interface apparatus with cable-driven force feedback and four grounded actuators
First Claim
1. An apparatus, comprising:
- a manipulandum adapted to be manipulated by a user as a medical device;
a medical simulation apparatus adapted to be a simulated body part, wherein the medical simulation apparatus is configured to receive the manipulandum therein, wherein the medical procedure simulation tool is a first simulation tool, the simulation apparatus adapted to receive a second simulation tool with the first simulation tool, wherein the simulation apparatus is configured sense positional information of both simulation tools simultaneously; and
an interface device coupled to the simulation apparatus and configured to be coupled to a host computer, wherein the host computer is adapted to run a software application simulating the manipulandum inside the medical simulation apparatus as a simulated medical device inside the simulated body part, wherein a portion of the medical simulation apparatus moves in response to a control signal from the host computer.

Abstract
A system for providing realistic sensation within a simulation system by providing tactile (haptic) feedback to a user. The system includes an engageable practice tool that the user engages and a mechanical simulation apparatus coupled to the practice tool. The mechanical simulation apparatus includes a ground member, a mechanical linkage rotatably coupled to the ground member, a linear axis member coupled to the practice tool and the mechanical linkage, at least four actuators coupled to the ground member, sensors for sensing movement of the actuators, and at least three cables in contact with the at least four actuators and coupled to the mechanical linkage. An interface device is coupled to the simulation apparatus and a host computer is coupled to the interface device for implementing an application program. The application program provides signals for the actuators to move the cables and thereby move the mechanical linkage.
