Disclosed is a video camera head comprised of at least two rigid printed circuit boards (PCBs) arranged in parallel planes. The at least two PCBs are mechanically supported one above the other by at least two external pins attached to the perimeters of the PCBs. The external pins fit into grooves cut into the edges of the PCBs. Several embodiments of the video camera head are described.

The present disclosure provides devices and methods for insufflating abdomens of subjects under direct visualization. Such devices and methods, in some implementations, include features for cleaning the devices, and certain implementations of the methods permit procedures wherein it is not necessary to use a typical obturator to place a cannula, resulting in safer procedures.

A miniaturized device providing hyperspectral imaging in real-time includes a body, a camera within the body, a micro-LED array arranged around the camera within the body, and an imaging controller within the body and coupled to the camera and the micro-LED array. The micro-LED array includes micro-LEDs of varying spectral bands. A method for controlling an imaging device includes providing LED timing information and LED intensity information to a micro-LED array, providing camera timing information to a camera for capturing a plurality of images, and receiving the plurality of images from the camera. The timing information includes a timing signal to each micro-LED of the micro-LED array and each timing signal includes a pulse. An image of the plurality of images is captured for a time period associated with each timing signal.

A medical device, configured for insertion into a body, may include an elongate member extending from a proximal end to a distal end, where the distal end may be configured to be positioned inside the body. The medical device may also include an imaging device positioned at the distal end. The medical device may further include a plurality of light sources positioned at the distal end, wherein a characteristic of light delivered through a first light source may be controlled independent of the characteristic of light delivered through a second light source.

The present invention relates to a micro endoscope camera module, including a first tube body having one or more objective lenses disposed therein; and a second tube body supporting the first tube body at a one side, wherein an image capturing means is disposed to be adjacent to a rear portion of the objective lens inside the second tube body. In addition, the present invention relates to a micro endoscope, in which the above-described micro endoscope camera module is disposed at the tip end of the scope, whereby it is possible to realize a high-quality image acquisition by disposing the image capturing means for image acquisition at the front end of the scope.

An illumination optical system includes a diffusion element that diffuses illumination light entering from a light source, the diffusion element emitting the illumination light. The diffusion element is formed by dispersing fine particles of at least one kind in a homogeneous medium that is made of a material different from the fine particles, and the diffusion element satisfies a specific conditional expressions.

An emitter assembly and waveform sensor assembly for visualizing a target is disclosed. The emitter assembly is configured to emit electromagnetic radiation and includes a first emitter configured to emit at least one of visible light, infrared radiation, or a combination thereof and a second emitter configured to emit structured electromagnetic radiation. The waveform sensor assembly is configured to detect the electromagnetic radiation emitted by the emitter assembly and obtain three-dimensional images corresponding to the detected electromagnetic radiation.

Borescopes, such as chip-on-a-tip laparoscopes and endoscopes, having variable and/or active focus lenses. In some preferred embodiments, a chip-on-a-tip borescope may comprise a tip assembly having a fixed focus lens and an active or variable focus lens. The active lens may be part of an active lens assembly, which may comprise a substrate, such as a printed circuit board, along with an active lens unit that may be configured to receive electrical signals, such as voltage steps, that may be used to change the shape of the lens component of the unit to change the focal distance of the device. The substrate may be physically coupled to other elements of the scope and may be electrically coupled with other elements of the scope, such as a voltage driver that may be provided in a printed circuit board in the handle of the scope, for example.

A medical device with a valve for autoclavability is disclosed. The medical device may include a cavity. A channel connects the cavity to an autoclave environment. The channel has a distal end and proximal end. The distal end of the channel may open to the autoclave environment and the proximal end may open to the cavity. A valve may be positioned in or near the channel. The valve may permit gas to flow from the cavity when a pressure inside the cavity is greater than a pressure in the autoclave environment outside the cavity. The valve may also prevent gas from flowing into the cavity when the pressure in the autoclave environment outside the cavity is greater than the pressure inside the cavity.
