Abstract

An interface device capable of communicating with a computer running a simulation program, such as a surgical simulation program, comprises an instrument capable of being manipulated by a user. The instrument is receivable within an orifice in an instrument receiving member, the instrument receiving member comprising a capture member engageable with the instrument and a sensor to sense a position of the instrument. The position of the instrument is then used by the computer to control a graphic image related to the simulation. In one version, the simulation is a simulation of a surgical instrument insertion procedure, such as an endoscopy procedure.

Claims (25)

1. An apparatus, comprising:

an instrument-receiving member defining an orifice and configured to receive an instrument having a distal end portion;

a capture mechanism disposed within the instrument-receiving member, the capture mechanism configured to releasably engage the distal end portion of the instrument and to move in an arcuate path of the instrument-receiving member, the instrument configured to slidably move along the arcuate path of the instrument receiving member, wherein the capture mechanism includes a shaft, the shaft coupled to the sensor, the sensor configured to detect a rotational motion of the shaft; and

a sensor configured to detect a position of the instrument and output a position signal responsive to the position of the instrument.

2. The apparatus of claim 1 , further comprising:

an actuator coupled to the instrument-receiving member and configured to provide force feedback to the instrument-receiving member responsive to the position signal.

3. The apparatus of claim 1 , wherein the instrument-receiving member is configured to allow the instrument to be selectively inserted and removed therefrom.

4. The apparatus of claim 1 , wherein the sensor is configured to send the position signal to a medical simulation system associated with a simulation of a medical procedure.

5. The apparatus of claim 1 , wherein the sensor is configured to send the position signal to a medical simulation system associated with a simulation of an endoscopic procedure.

6. The apparatus of claim 1 , wherein the capture mechanism includes a bendable shaft.

7. The apparatus of claim 1 , further comprising:

an actuator configured to apply force feedback to the capture mechanism when the instrument is engaged by the capture mechanism.

8. The apparatus of claim 1 , further comprising:

a wheel coupled to the capture mechanism and configured to rotate, the arcuate path defined by rotation of the wheel.

9. The apparatus of claim 1 , further comprising:

a wheel coupled to the capture mechanism and configured to rotate, rotation of the wheel defining the arcuate path;

a groove disposed in the wheel; and

a belt configured to cover the groove of the wheel.

10. The apparatus of claim 1 , further comprising:

a wheel configured to rotate, rotation of the wheel defining the arcuate path; and

a belt configured to drivingly engage the wheel.

11. The apparatus of claim 1 , further comprising:

a wheel configured to rotate, rotation of the wheel defining the arcuate path;

a belt configured to drivingly engage the wheel; and

an actuator coupled to the belt and configured to apply force feedback to the instrument.
