A laparoscopic medical device includes an oximeter sensor at its tip, which allows the making of oxygen saturation measurements laparoscopically. The device can be a unitary design, wherein a laparoscopic element includes electronics for the oximeter sensor at a distal end (e.g., opposite the tip). The device can be a multiple piece design (e.g., two-piece design), where some electronics is in a separate housing from the laparoscopic element, and the pieces (or portions) are removably connected together. The laparoscopic element can be removed and disposed of; so, the electronics can be reused multiple times with replacement laparoscopic elements. The electronics can include a processing unit for control, computation, or display, or any combination of these. However, in an implementation, the electronics can connect wirelessly to other electronics (e.g., another processing unit) for further control, computation, or display, or any combination of these.

A stylet assembly and method of forming an in vivo image acquiring stylet assembly. The stylet assembly includes an elongate flexible body and an image acquiring device that is supported at a location that is offset from an in vivo facing terminal end of the stylet assembly. A terminal end portion of the stylet assembly is defined by a manipulator that is oriented to extend in a crossing direction relative to a longitudinal axis of the elongate body. The terminal end portion of the stylet assembly is steerable relative to the elongate body and is operable to manipulate positions or adjacent anatomy and/or effectuate guidance of the imaging device relative thereto during use.

The present disclosure relates to visualizing an operative field in the context of a dental operating theater, and more specifically, to a portable, modular, multifunctional intraoral imaging system to assist a practitioner in performing a medical or dental procedure in a confined space (e.g., intraoral cavity or mouth of a patient). The system may include an intraoral camera apparatus having a camera unit equipped with a wireless transmitter, and a viewscreen mounted to an articulated stand or dental delivery unit, wherein the camera wirelessly may transmit an image to a viewscreen located directly in front of a dental practitioner. The practitioner may look directly ahead at a high-definition screen to view the operative field. A dental practitioner may use the apparatus to perform micro-surgical procedures in a confined operative area with less-than-ideal visibility and access, without the present, though generally accepted, physical difficulties and limitations.

An endoscope may include a needle and a scope, which may optionally be contained in an elongated shaft. The endoscope may further include a handle comprising at least one button, a visualization component, a reservoir configured to contain a composition, and a dispensing mechanism. The at least one button, the needle, the reservoir, and the dispensing mechanism may be operably linked to cause the composition to be dispensed from the reservoir through the needle to a portion of an ear. A method for using such an endoscope may include inserting the endoscope into a portion of an ear, using the visualization component to visualize the portion of the ear, and pressing the at least one button to dispense the composition from the reservoir through the needle to the portion of the ear.

An endoscope that integrates the functions of an optical tower into a portable device, while eliminating the use of cords or cables that carry light, video signals or images, and power to the endoscope that may conflict with the movement of a surgeon and the members of the surgical team, or other operators in non-medical related applications is provided. The endoscope incorporates a camera, an image processor, a light source, a transmitter, a communication interface, a control interface, and one or more of a power source in a single portable unit or enclosure. The camera is in electrical communication with the image processor and supplies images and video to the image processor obtained via an elongated endoscope tube. The light source illuminates a viewing field of the endoscope via the elongated tube.

An illumination optical system for endoscope includes a rod lens as an optical element. The optical element includes a proximal end surface through which light enters and a distal end surface configured to emit the light. The distal end surface includes a diffusion region configured to diffuse emitted light. The diffusion region includes a plurality of concave portions and a plurality of peripheral regions surrounding the concave portions. Each concave portion includes a plurality of inclined surfaces as total reflection surfaces that are inclined with respect to the distal end surface. Each peripheral region includes a transmission surface configured to emit light totally reflected by the total reflection surfaces after passing through the proximal end surface and light not totally reflected by the total reflection surfaces.

A system for self-imaging a body portion includes a self-imaging device and an ancillary device that is attachable to the self-imaging device. The self-imaging device has a base member, a camera located within the base member and a guide element for transmitting light along a path extending between the camera and an exposed tip of the guide element that opens out of the self-imaging device at a given side of the device. The ancillary device is arranged to attach to the self-imaging device at said same given side while substantially not obstructing incoming light arriving towards the self-imaging device from being transmitted via the guide element towards the camera.

A device for visualization of internal tissue of a patient's uterus, the device including a hand-held control unit, an elongated member, and an image capturing tip. To provide better light conditions, to reduce heat generation and related problems with excessive heating and to improve the ergonomic conditions, a device including an illumination structure having at least a first and a second optical fibre is provided.

An endoscope device is provided. The device comprises: an elongate member comprising a proximal end and a distal end, and a camera is located at the distal end of the disposable elongate member; one or more external guiding elements configured to guide an articulation movement of the distal end of the elongate member, and each of the one or more external guiding elements is individually controlled; and a handle component removably attached to the proximal end of the elongate member.

The present disclosure relates to a display system including a capsule image view, a 3D mini-map, and a 3D panoramic view, and a method of generating a 3D panoramic view. Specifically, according to the present disclosure, it is possible to infer the shape of an organ using a 3D mini-map and to simultaneously identify whether or not the capsule endoscope captures the images, and information on the position and posture of the capsule endoscope at primary captured points by visualizing the actual movement path of the capsule endoscope, thereby improving the accuracy of examination, and since multiple 2D images captured by a single capsule endoscope are able to be viewed as a single 3D panoramic image without changing the structure of the capsule endoscope, it is economical and the viewing angle of the image is able to be increased, thereby reducing the examination time and fatigue of the examiner.
