Virtual surgery system instrument
First Claim
1. A surgical simulator user input device comprising:
- a housing having a first virtual orifice wherein said first virtual orifice is connected to a computer used for conducting a virtual surgery procedure, and wherein said first virtual orifice is adjustable by the computer to represent a particular orifice of a human body;
a first virtual medical instrument corresponding to a real medical instrument, wherein said first virtual medical instrument includes a second virtual orifice connected to the computer for conducting a virtual surgery procedure and wherein said first virtual medical instrument extends into said housing through said first virtual orifice; and
a second virtual medical instrument extending through said second virtual orifice in said first virtual medical instrument.

Abstract
A virtual surgery system or virtual testing system provides a simulation or test based on image data. A simulator combined with a real exam requires simulation tasks by a test taker. Additionally, a surgical procedure may be simulated using image data of a patient in devices simulating the physical instruments a surgeon uses in performing the actual procedure, for example. The user input device, such as a mouse, three dimensional mouse, joystick, seven dimensional joystick, fall size simulator, etc., can be used in a virtual simulation to move through the image data while the user looks at the data and interaction of the input device with the image data on a display screen. Force feedback can be provided based on based on physical constraint models (of the anatomy, for example), or based on edge and collision detection between the virtual scope or virtual tool used by the operator and walls or edges of the image data in the image space. The virtual simulator may be used as a teaching, training, testing, demonstration, or remote telesurgery device, for example.
