A system for intraoral scanning comprises a scanner to generate image data of a dental site and a computer readable medium. The computer readable medium includes instructs that, when executed by a processing device, cause the processing device receive a selection of library data for a reference object from library data for a plurality of reference objects in a library, receive the image data generated by the intraoral scanner, the image data comprising a representation of a dental site comprising the reference object, and align the library data for the reference object with the image data.

In a method of generating a virtual 3D model of a dental site, scan data comprising a plurality of images of a dental site is received during an intraoral scan. An analysis of an image is performed. A representation of a reference object with known properties is identified in the image based on the analysis. A virtual 3D model of the dental site is generated based on the plurality of images. The image and/or the virtual 3D model of the dental site is modified by adding additional data about the reference object to the intraoral image and/or the virtual 3D model based on the one or more known properties of the reference object. If the image is modified, it may be modified prior to generation of the virtual 3D model, and the virtual 3D model may be generated using the modified image.

A portable endoscopic inspection system comprises an endoscope having a proximal end with a flanged eyepiece for observation and a distal end with a lens assembly for insertion into a region of interest. A light port transports incident light to the region of interest along an lighting pathway, and reflected light is transported along an imaging pathway from the lens assembly to the eyepiece. A wireless imaging unit comprises a light source which detachably couples to the light port for generating the incident light, and an imaging sensor for recording images of the reflected light from the eyepiece. The wireless imaging unit comprises a variable coupling system which mechanically couples the imaging sensor to the flanged eyepiece independent of the shape and/or size of the flange of the eyepiece.

In a method of generating a virtual 3D model of a dental site, scan data comprising an intraoral image is received during an intraoral scan of a dental site. A representation of a foreign object is identified in the intraoral image based on a color analysis of the scan data. The intraoral image is modified by removing the representation of the foreign object from the intraoral image. Additional scan data comprising a plurality of additional intraoral images of the dental site is received during the intraoral scan. A 3D surface of the dental site is then generated using the modified intraoral image and the plurality of additional intraoral images.

One embodiment provides a device, method, and wireless endoscope. The wireless endoscope includes a light integrated in a first portion. The wireless endoscope also includes a lens positioned proximate the light in the first portion. The light and the lens are inserted into a body. The first portion is interchangeable. The wireless endoscope also includes a connector physically securing the first portion to the second portion. The second portion is not inserted into the body. The wireless endoscope also includes a camera capturing video content received through the lens. The wireless endoscope also includes a wireless transmitter transmits the video content to a receiver associated with a displaying device.

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 system for intraoral scanning comprises a scanner to generate image data of a dental site and a computing device. The computing device receives the image data of the dental site, the image data comprising a representation of the dental site and a representation of a reference object at the dental site. The computing device selects library data for the reference object from library data for a plurality of reference objects in a library. The computing device aligns the library data for the reference object with the image data.

A surgical light source system for cooling high-powered arthroscopic light emitters. The surgical light source system includes a housing having a proximal end and a distal end with a tube connected to the proximal end. The system also includes a light source at the distal end of the housing which is connected to a remote power source. The system has a plurality of fins extending around the light source within the housing and a remote fan connected to the tube. The remote fan is adapted to draw air across the fins, forming a heatsink within the housing.

An endoscopic imaging device is disclosed. The device includes a body portion configured to be held in a user's hand and an endoscope portion configured to direct light onto a target. At least one excitation light source is configured to excite autofluorescence emissions of tissue cells and fluorescence emissions of induced porphyrins in tissue cells of the target. A white light source is configured to illuminate the surgical margin during white light imaging of the target. The device also includes an imaging sensor and a first optical filter configured to filter optical signals emitted by the target responsive to illumination with excitation light and permit passage of autofluorescence emissions of tissue cells and fluorescence emissions of the induced porphyrins in tissue cells to the imaging sensor. A second optical filter configured to filter optical signals emitted by the target responsive to illumination with white light and permit passage of white light emissions of tissues in the surgical margin to the imaging sensor. The endoscopic imaging device may be modular and comprise a base body portion that releasably receives, in an interchangeable fashion, one or more endoscopic optical housing portions.
