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

1. 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.

2. The method according to claim 1, further including the step of permitting the user to select a medical procedure from a plurality of medical procedures.

3. The method according to claim 1, wherein the medical procedure is a surgical procedure.

4. The method according to claim 1, further including the step of permitting the user to select from a plurality of medical procedures including laparoscopic surgical procedures of extraperitoneal herniorrhaphy and bladder suspension.

5. The method according to claim 1, wherein step (a) requests information by displaying a list of selectable options relating to the next step of the medical procedure.

6. The method according to claim 1, wherein step (a) requests information regarding a medical instrument for use in the next step of the medical procedure.

7. The method according to claim 6, wherein a visual image of the medical instrument is displayed.

8. The method according to claim 5, wherein the list of options includes a plurality of medical instruments for possible use in the next step of the medical procedure.

9. The method according to claim 8, further including the step of permitting the user to individually highlight potential medical instruments for selection.

10. The method according to claim 9, wherein a plurality of visual images of medical instruments are retrievably stored, the plurality of visual images corresponding to the plurality of medical instruments in the list of options, and further including the step of displaying the visual image of the medical instrument highlighted by the user.

11. The method according to claim 1, further including the step of:

(g) returning to step (a) to request the user to input information relating to the next step in the medical procedure, wherein;

(i) the next step is the same as the step from the previous execution of step (a), if the user input was incorrect; and

(ii) the next step is advance beyond the next step from the previous execution of step (a), if the user input was correct.

12. A computer readable storage medium encoded with a computer program for controlling the operation of an interactive medical training system having a display, said storage medium comprising:

means for displaying a first video segment on a portion of the display, the first video segment including a portion of a laparoscopic surgical procedure;

means for displaying a second video segment on the display simultaneously with the first video segment;

said second video segment comprising an alternative view of the same portion of the laparoscopic surgical procedure shown in the first video segment;

means for requesting input from a user relating to a step in the laproscopic surgical procedure;

means for receiving the input; and

means responsive to the input for interpreting the input, the interpreting means being operative to inform a user whether the input was correct; and

means for periodically generating a random error relating to information inputted by the user relating to a step in the laproscopic surgical procedure.

13. The computer readable storage medium according to claim 12, wherein the medical training system provides instructive information on surgical procedures.

14. The computer readable storage medium according to claim 13, wherein the medical training system provides instructive information relating to laparoscopic surgical procedures, including extraperitoneal herniorrhaphy and bladder suspension procedures.

15. The computer readable storage medium according to claim 12 further including means for customizing said laparoscopic procedure based upon selected parameters relating to a patient scenario.

16. The computer readable storage medium according to claim 15 wherein said parameters are selected from the group consisting of patient weight related parameters, patient size related parameters or origin or GSI surgical procedure parameters.
