Abstract: A light source for use with a scope is provided. The scope includes a body having a proximal end and a distal end, a light input port disposed on the body, a light output port disposed on the body and disposed distally of the light input port and a light transmission channel extending between the light input port and the light output port. The light source includes a housing including a light output port and a light source disposed within the housing. The housing is adapted to mount to the body of the scope to provide light to the scope.

Abstract: A cannula is divided longitudinally into a camera chamber and an instrument passage. The distal end of the camera is sealed by an optically clear member. In use, a camera assembly which includes a camera sled on which are mounted a charge-coupled device camera and lights is inserted into the camera chamber and a conventional laparoscopic instrument is inserted into the patient through the instrument passage. The camera sled is isolated from the patient by the cannula, eliminating the need to sterilize the camera sled. The instrument is held in position by an attachment member which extends from the cannula. This allows the surgeon to control the position of the instrument and the camera with one hand. The cannula includes a port for connecting a source of CO2 to inflate the patient's abdominal cavity and a port for connecting a conventional suction/irrigation trumpet-valve assembly.

Abstract: In one embodiment, an imaging unit to be mated with an image-producing scope via a coupler includes at least one imaging unit body, and an image sensor disposed within the at least one imaging unit body. The imaging unit further includes a refractive lens movably disposed within the at least one imaging unit body, and at least one first component adapted to receive an output from a focusing mechanism disposed on a body of the coupler. The at least one first component is configured and arranged so that movement of the focusing mechanism with respect to the coupler body causes the lens to move within the at least one imaging unit body to focus an image produced by the scope onto the image sensor. In another embodiment, a method for operating an imaging system including an image-producing scope, a refractive lens, and an image sensor involves providing a coupler that is free of the refractive lens.

Abstract: A charge-coupled device camera is removably mounted in a adaptor and the adaptor is removably mounted in the viewing aperture of a speculum. The camera is connected to a display device, such as a video monitor, by a cable. At least one high-intensity light is also mounted in the adaptor with the axis of the light parallel to that of the camera. The light is connected to an adjustable power source by a power supply cord. In one embodiment of the invention, a cervical positioner is provided to allow the physician to align the patient's cervix with the camera's axis for optimal viewing.

Abstract: A surgical positioning device that includes a body having a first un-stressed configuration and at least one fluid channel to receive a fluid. The at least one fluid channel is constructed and arranged to transform the body of the surgical positioning device from the first un-stressed configuration to a second configuration when fluid is forced into the at least one fluid channel. The surgical positioning device can include one or more working channels that permit surgical devices to be remotely positioned by the surgical positioning device by adjusting an amount of fluid forced into the at least one fluid channel.

Abstract: A surgical/diagnostic imaging device for use in interabdominal, interthoracic, and other surgical and diagnostic procedures includes an image sensor pivotally mounted at the distal end of a support. In use, the image sensor and support are contained within a disposable sterile sheath, and the distal portion of the sheath is inserted into the patient through an incision. The imaging device includes actuators to move the image sensor in elevation and azimuth.

Abstract: According to one embodiment, an apparatus for mating a first instrument having an image sensor to a second instrument includes: a coupler having first and second ends respectively adapted to mate with the first and second instruments; a sheath, mounted to the coupler, that is extendable to accommodate at least one portion of the first instrument when the first instrument is mated with the first end of the coupler; and a focusing mechanism to focus light onto the image sensor, the focusing mechanism being uncovered by the sheath when the first end of the coupling device is mated with the first instrument and the sheath is extended to accommodate the at least one portion of the first instrument. According to another embodiment, an apparatus for mating with an imaging-producing scope includes: an imaging unit including an image sensor and a lens; and a coupler having first and second ends, the first end being adapted to mate with the imaging unit and the second end being adapted to mate with the scope.
