An oral imaging device includes a base, a camera module, and a plurality of light source modules. The base includes a camera component, an opening surface, and a plurality of light source components connected to two sides of the camera component. A slant angle exists between each light source component and the camera component. The slant angle is a non-right angle. The opening surface is substantially parallel to the camera component. The camera module is located on the camera component and faces the opening surface. The plurality of light source modules each are located on each light source component and configured to project a light beam onto the opening surface. A center ray of the light beam passes through a center point of the opening surface.

Disclosed are an oral fixation device for radiation therapy and an oral fixation method in treatment of a lip cancer. The oral fixation device for radiation therapy includes a first spacer including a first insert inserted between a first lip portion and a first gum portion, and a tooth support coupled to the first spacer at a side of the first spacer disposed inwardly of an oral cavity, wherein teeth or gums of a patient is supported on the tooth support, wherein a first spacer has a specific thickness to maintain a specific spacing between the first lip portion and the first gum portion, wherein the first lip portion includes a treatment target portion to be subjected to the radiation therapy.

The present invention addresses the problem of providing a small-sized, low-cost medical optical imaging device capable of irradiating even a deep portion of a dental root canal. Provided is a medical optical imaging device (4) that is provided with an illumination unit (6) for emitting illumination light to a subject, an imaging section (7) for imaging the subject, and a controller (8) for controlling at least the imaging section (7). The imaging section (7) is provided with an imaging lens system (71) and an imaging element (72) for receiving an optical image created by the imaging lens system (71). When viewed from the subject side, the illumination unit (6) is disposed in front of the imaging lens system (71) and overlapping the imaging lens system (71).

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

A support rig for a medical instrument can hold a medical instrument that is inserted into a patient in a fixed position and orientation relative to patient, so that the position and orientation of the medical instrument is not affected by the breathing or other motion of the patient. The support rig and medical instrument can be radiolucent and non-metallic, so that an image can be taken of the patient while the medical instrument is inserted in the patent and held by the support rig. The radiolucent support rig and medical instrument can allow for imaging, including x-ray, CT, and/or MRI, to occur simultaneously during the surgery. Surgical outcomes can be improved by using imaging to provide information about a tumor and/or anatomical structures during surgery.

An aspiration prevention system may be configured to keep items from moving from a mouth of a patient into a throat of the patient. The system may include a mouth prop, a frame, and an air-permeable barrier. The mouth prop may have a top surface configured to abut top teeth of the mouth, a bottom surface configured to abut bottom teeth of the mouth, and a frame coupling feature. The frame may have a barrier retention feature configured to retain an air-permeable barrier, and a prop coupling feature that is attachable to the frame coupling feature of the mouth prop in a position in which the frame at least partially covers the throat.
