An endoscope module including an annular prism, an annular lens, an annular stop, and an annular image sensor is provided. The annular prism has an annular reflective inclined surface, a light incident surface, and a light emitting surface. The light incident surface faces a side surface and the light emitting surface faces away from a front surface. The annular stop is disposed on a side of the light incident surface of the annular prism and surrounds the annular prism. The annular lens is disposed between the annular prism and the annular image sensor. A lateral light from the side surface is reflected to the annular lens by the annular reflective inclined surface after passing through the annular stop and then entering the annular prism, and is then condensed to the annular image sensor by the annular lens.

A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

The present specification describes a circuit board design that uses circuit boards for illuminator sets associated with the various optical assemblies. In one configuration, front and side illuminators are assembled on front and side illuminator circuit boards. Leaf connectors associated with each illuminator are provided to interface with a common base board.

The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.

The present disclosure relates generally to systems and methods for performing endoscopic procedures, and, more particularly, to location and access devices, systems, and methods for gastrojejunostomy procedures. In an aspect a medical device locator may include an elongate member having a proximal end, a distal end, a longitudinal axis, and a length extending along the longitudinal axis. An inflatable member may be disposed about the distal end of the elongate member. The inflatable member may have a first inflated volume and a second inflated volume larger than the first inflated volume. The elongate member may include a fluid lumen extending therealong. The fluid lumen may be in fluid communication with the inflatable member and may be configured to pulsate the inflatable member between the first inflated volume and the second inflated volume.

The present specification describes a circuit board design that uses circuit boards for illuminator sets associated with the various optical assemblies. In one configuration, front and side illuminators are assembled on front and side illuminator circuit boards. Leaf connectors associated with each illuminator are provided to interface with a common base board.

There is provided herein a tip section of a multi-viewing element endoscope, the tip section comprising: two or more side-pointing viewing elements positioned at or in proximity to a distal end of said tip section, wherein each of said two or more side-pointing viewing elements having a discrete illuminator associated therewith, wherein the field of view provided by the two or more side-pointing viewing elements covers a front and side views; a working channel configured for insertion of a surgical tool; and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.

A detection package structure, comprising: an exterior tube; a detection assembly, a flexible printed circuit (FPC), a module base, and lighting members which are all disposed inside the exterior tube. The FPC includes a main flexible plate and minor flexible plates. The invention uses detection conductive materials and detection wiring parts to implement electric conduction-directed soldering, whereby to prevent from direct soldering of cables and detection assembly and enlarge soldering spots. It can lower the difficulty of soldering operation, enhance the strength and reliability of soldering, promote the stability of the electric conduction-directed soldering in various dynamic states. Dimensional errors or external force are less likely to affect the performance of electric-conduction-directed soldering due to the flexibility of the FPC which can guarantee electric connection and convenience assemblage and improve the stability of electric conduction-directed soldering. The bendability of the FPC favors reducing the radial size of the package structure.

A catheter configured for placement within a bodily lumen, comprises: a catheter sheath defining a first lumen for medical tools; and an exchange segment defining a second lumen for a guidewire. A proximal end of the exchange segment is joined with a distal end of the catheter sheath in a lengthwise direction forming an angle therebetween, such that the second lumen is laterally offset by a distance and angled with respect to the first lumen. When the catheter is placed within a patient's anatomy, the catheter sheath and/or the exchange segment straightens out so that the axis of the second lumen and the axis of the first lumen become substantially parallel to each other. The offset distance between the axes of sheath and exchange segment depends mainly on the diameter of the guidewire to be used, on the diameter of the sheath, and the angle of the junction.

Systems and methods for a tethered optical imaging probe configured to be integrated into an optical system for medical diagnosis are provided. In one configuration, the present disclosure provides a tethered optical imaging probe including a motor arranged within a swallowable capsule. A rotational speed of the motor is actively controlled by a feedback signal.
