摘要:
An apparatus and method for protecting a body member during a body intrusive procedure in a region adjacent the body member to be protected (14) includes infrared energy (18) introduced into a light guide (17) which is introduced into the body member to be protected; and visible light (2) is introduced into the region, either of the lights may be pulsed at the frame rate of a monitor (12) energized by a video camera (10) that receives light from such region, the camera being sensitive to infrared energy as well as visible light. In a furhter embodiment, infrared light is removed from the visible light and a polarizing filter may be employed to filter the light to the camera to reduce glare. A body member to be located or illuminated may be illuminated from one side and the location of the illuminator (112) detected by a probe (116) on the other side of the body member.
摘要:
In order to protect members adjacent to an invasive procedure on a body, the member to be protected is illuminated preferably with infrared light energy and the entire site of the invasive procedure is viewed through an optical system that conducts both infrared and visible light energy to one or more video cameras (127). Various structures may be employed to separate the visible and infrared light energies so that the signals representing such light energies may be processed separately and differently if desired and then recombined for display or separately displayed on a video color monitor (128). The site is illuminated by light from, in one instance, an endoscope (129). Situated between the source and the endoscope is a filter that blocks infrared light energy and provides color correction of the light provided to the camera(s).
摘要:
The present invention provides a method and apparatus for illuminating the region of a body member to be subjected to a surgical procedure by inserting an infrared conducting fiber (6) into the body member (12), the fiber emitting infrared light energy over a limited range at the precise location where the procedure is to occur. The procedure may involve an organ (14), a blood vessel, even a nerve. Mechanisms and detectors (4,20) may be employed to locate the infrared emissions.
