An improved computer based surgical video overlay system that allows relevant surgical data from a surgical apparatus to be combined as a graphic image with the video image of a surgical procedure in which the data from the surgical apparatus is sent wireless to the video overlay console. Elimination of the data cable between the surgical apparatus and the video overlay console is advantageous in an operating room environment. The same computer based surgical video overlay system runs computer program that occupies a user interface to allows definition of operation modes, input of relevant data, selection of data overlay graphic screen templates and various methods for customization. A time coded-data file is created and stored including all the relevant parameters of a surgical procedure. This file contains the same time-code included in the graphic image overlaid in the surgical video signal. An precise match can be performed between the recorded data on file and the surgical video recording. An audio pre-amplifier section is provided to include surgical apparatus meaningful sounds produced during surgery. The alternative embodiment considers the use of an embedded computer within the video overlay console making the system capable of standalone operation providing a user interface and data input/output capabilities.
- A wireless video overlay system for a surgical apparatus comprising:
- The video overlay system of claim 1 wherein said surgical apparatus is used for ophthalmic surgery
- The video overlay system of claim 1 wherein said computer is a personal computer
- The video overlay system of claim 1 wherein said computer is an embedded computer enclosed within said video overlay console
- The video overlay system of claim 1 further including a signal detector circuit that informs a user about the correct status of the required input signals
- The video overlay system of claim 1 further including an audio pre-amplifier to produce a recordable audio output signal from the sounds captured by a microphone
- The video overlay system of claim 1 further including an audio synthetizer to produce an audio signal determined by the analysis of said surgical apparatus data signal
- The video overlay system of claim 1 further including a control panel for user selection of video overlay console operation mode
- The video overlay system of claim 1 further including a control panel for user selection of video overlay graphic templates
- The video overlay system of claim 1 further including data storing means to accumulate said input data signals together with a time code
- The video overlay system of claim 1 further including data input/output means to export data stored during operation and to load graphic overlay templates
- The output video signal of claim 1 further including a graphic representation of a time code
- The output video signal of claim 1 further including a graphic representation of predetermined information selected by a user
- A method for obtaining a user configurable surgical video overlay output signal by overlaying a graphic representation of output data signals produced by a surgical apparatus onto a surgical field video signal comprising:
- The method of claim 14 wherein said surgical apparatus is used for ophthalmic surgery
- The method of claim 14 further providing a signal detector circuit to inform a user about the correct status of the required input signals
- The method of claim 14 further providing an audio pre-amplifier to produce a recordable audio output signal from the sounds captured by a microphone
