Abstract

This invention relates to an illumination control device (200) in an endoscopic imaging System comprising; a control member (210) wherein the control member comprises; an aperture (404) in the form of a variable opening in a carrying or bearing member (402), and disposed between the optical port (160) and the light source (112), the movement of the aperture (404) across the optic port (160) corresponding to the movement of the control member (210) controls the area of the optic port (160) transmitting the light to the endoscope (190), and in turn controlling the illumination intensity at the examination site; and a grating (406) having at least two holes (410, 412), the pattern of the holes (410, 412) being variable across a guiding curve (414) so as to gradually vary the opacity of the grating (406), the illumination intensity control being dependent on the width of the aperture (404) and the opacity of the grating (406).

Description

technical field [0001] The present invention generally relates to an illumination control system, in particular to an illumination control device for an endoscope light source. Background technique [0002] Minimally invasive procedures or surgery (MIP or MIS), including endoscopic, laparoscopic, endoscopic-assisted or laparoscopic-assisted procedures, are known and offer benefits to the patient, such as limited incisional trauma, reduced pain, limited scarring, fewer hospitalizations and an earlier return to normal functional status. To perform such procedures, an external light source, typically coupled to an optical fiber and an endoscope, is used to illuminate the surgical space. Typically, it is desirable to control the intensity of the illumination to improve and adjust the display of the site according to the needs of the surgeon, operator and / or medical practitioner. [0003] Several techniques and devices are used to control the intensity of the illumination, such...
