Description

Medical dynamic video comparison teaching system and method

A teaching system and method thereof, in particular, a marking teaching system and method thereof for providing a comparison between original medical surgical videos and marked surgical videos.

With the development of video technology, teaching through video has gradually been realized. Medical teaching can be further improved through video. That is, during the medical operation, the surgical procedure can be recorded by filming. In subsequent medical teaching, the surgical procedure can be taught through video playback and the teacher's explanation.

However, if there is no teacher's explanation, it is undoubtedly very difficult to learn the surgical procedure by simply providing a video. That is, the video playback lacks the marking of the parts to assist learning. The goal of the present invention is to enable learning of the surgical procedure through the video without the teacher's explanation.

In summary, it can be seen that the prior art has long had the problem of lack of markings to assist learning when playing medical videos, so it is necessary to propose improved technical means to solve this problem.

In view of the problem that the prior art lacks marked comparison to assist learning when playing medical videos, the present invention discloses a medical dynamic video comparison teaching system and method, wherein:

The medical dynamic video comparison teaching system disclosed by the present invention comprises: an image database and a computer device, the computer device is connected to the image database, and the computer device comprises: a non-transient computer-readable storage medium and a hardware processor.

The image database stores a plurality of image data, each of which includes an original surgical video, a marked surgical video, and a plurality of frame display information of the marked surgical video, and each frame information includes at least one marked area, a unique color code corresponding to the at least one marked area, and an area description corresponding to the at least one marked area.

The non-transitory computer-readable storage medium is used to store a plurality of computer-readable program instructions; the hardware processor is electrically connected to the non-transitory computer-readable storage medium, and the hardware processor is configured to execute the computer-readable program instructions to execute:

The user interface display module displays a user interface including an original video playback area, a marked video playback area, and a surgical feature mark description area.

When the video playback module plays the original surgical video in the original video playback area or plays the marked surgical video in the marked video playback area, it searches for the corresponding marked surgical video or original surgical video from the image database to play the searched marked surgical video in the marked video playback area or the original surgical video in the original video playback area.

When the marking area module plays the marking surgery video in the marking video playback area, it fills at least one marking area in each frame of the marking surgery video with the corresponding color code according to the information of each frame of the marking surgery video and displays the corresponding area description. When the marking area corresponding to the surgical tool described in the area is selected, the marking area overlapping with the selected marking area is presented in the specified presentation method.

The marking description module displays at least one surgical feature mark in the marking description area, and at least one surgical feature mark corresponds to at least one marking area. Each surgical feature mark is displayed according to at least one marking area of the corresponding frame of the marked surgery video playback. When the marking area corresponding to the surgical tool in the area description is selected, at least one surgical feature mark corresponding to the marking area overlapping with the selected marking area is presented in a specified presentation manner.

The medical dynamic video comparison teaching method disclosed in the present invention is executed by a computer device connected to an image database, and comprises the following steps:
