Abstract
Abstract An interactive medical training device includes a computer system having a display, wherein the computer system is programmed to provide education and training in medical procedures, including laparoscopic surgical procedures. This aspect is achieved by configuring the system to display, on a portion of the display, a video window. The video window displays a prerecorded video segment illustrating a portion of a laparoscopic surgical procedure. The system requests a user to input information relating to a next step in the surgical procedure, which advantageously keeps the user engaged in the training session. This "next step" information may include, for example, selecting an appropriate medical instrument or selecting a location for operating. The user inputs the requested information through an input device, such as a mouse, a keyboard, a touch-sensitive screen, or other input device. The system then receives and interprets the user input and informs the user as to whether the input is correct. Preferable, if the input is correct the system will display a prerecorded video segment illustrating the next step of the surgical procedure.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
157 words
A method for training a user in a medical procedure utilizing an interactive computer system, said medical procedure having a plurality of steps, said method comprising the steps of: (a) requesting a user to input information into said computer system relating to a step in the medical procedure; (b) said computer system receiving the requested input; (c) said computer system interpreting the requested input to determine whether it is correct; (d) said computer system displaying a video segment corresponding to the information inputted by the user relating to said step of the medical procedure, if the input is correct; (e) said computer system informing the user that the input was incorrect, if the input is incorrect; and (f) said computer system periodically generating a random error relating to information inputted by the end user relating to the medical procedure from a set of predetermined errors which may occur in said medical procedure and displaying said random error.
Claim 2
Independent Claim
157 words
A method for training a user in a medical procedure utilizing an interactive computer system, said medical procedure having a plurality of steps, said method comprising the steps of: (a) requesting a user to input information into said computer system relating to a step in the medical procedure; (b) said computer system receiving the requested input; (c) said computer system interpreting the requested input to determine whether it is correct; (d) said computer system displaying a video segment corresponding to the information inputted by the user relating to said step of the medical procedure, if the input is correct; (e) said computer system informing the user that the input was incorrect, if the input is incorrect; and (f) said computer system periodically generating a random error relating to information inputted by the end user relating to the medical procedure from a set of predetermined errors which may occur in said medical procedure and displaying said random error.
