An instrument for accessing and visualizing hollow organs is provided. The instrument includes a mouthpiece having a perforated mask and a sleeve having a generally cylindrical or ovoid shape extending from the perforated mask substantially perpendicularly thereto and defining a channel. The instrument further includes sucking means having a suction chamber or closed volume that is restrained to the mask on the side where the sleeve is formed. The suction chamber has a plurality of through openings adapted to allow fluid communication with a surrounding environment, an intake opening communicating with the suction chamber formed on the mask, wherein the through openings are formed on the skirt of a dome-shaped member which delimits the suction chamber.

Apparatus for improving image guidance in radiation therapy applications are described. In one aspect, a patient support with integrated radiopaque markers is described. In another aspect, a bite block with integrated sensors, radiopaque markers, or both, is described. The integrated sensors may include a radiation detector, a pH sensor, or both. Radiation detectors that may be used include a dosimeter. As an example, the dosimeter may include a film dosimeter, an ion chamber dosimeter, a diode dosimeter, or other suitable dosimeters and combinations thereof.

The present disclosure involves object recognition as a method of registration, using a stereoscopic camera on Augmented Reality (AR) glasses or an endoscope as the image capture technology. Exemplary objects include surgical tools, anatomical components or features, such as bone or cartilage, etc. By detecting just a portion of the object in the image data of the surgical scene, the present disclosure may register and track a portion of the patient's anatomy, such as the pelvis, the knee, etc. The present disclosure also optionally displays information on the AR glasses themselves, such as the entire pelvis, the femur, the tibia, etc. The present disclosure may include combinations of the foregoing features, and may eliminate the need for electromagnetic, inertial, or infrared stereoscopic tracking as the tracking technology.

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 teeth support coupled to the first spacer at a side of the first spacer disposed inwardly of an oral cavity, wherein teeth or a gum of a patient is supported on the teeth 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.

Guidewires and methods useable in conjunction with image guidance systems to facilitate performance of diagnostic or therapeutic tasks at locations within the bodies of human or animal subjects.

A bite block generally comprising a firm, hollow tube, the inner diameter of which is adapted to accommodate the finger (e.g., the index finger) of a dental professional (e.g., dentist, hygienist), healthcare worker, parent or caregiver. In one implementation, one of the opposed ends of the bite block is closed, with the opposite, remaining end being open as needed to accommodate the advancement of the finger into the interior of the bite block. The bite block is provided with exterior surface characterizations or aesthetic features/attributes which are indicative of a juvenile motif, and is further provided in a shape and with corresponding dimensions such that it is particularly suited for advancement into, and accommodation within, the interior of a young child's mouth in a manner which minimizes discomfort to the child.

A bite block includes a body defining a first side wall, a second side wall, a first bite surface extending between the first side wall and the second side wall, and a second bite surface extending between the first side wall and the second side wall, the second side wall arranged to be positioned adjacent an interior portion of a patient's cheek. An LED is positioned within the body and positioned to emit light away from the interior portion of the patient's cheek. A battery is positioned within the body and is connected to the LED and a switch is positioned within the body and actuatable through contact with an exterior portion of the patient's cheek to selectively provide power to the LED, wherein the body defines an inseparable component that cannot be disassembled without destroying the body.
