An intraoral scanner includes a probe with a sensing face, patterned light sources that are coupled to the probe, un-patterned light sources coupled to the probe, near infrared (NIR) light sources couple to the probe, cameras coupled to the probe, and a processing device coupled to the probe. The processing device is configured to control an operation of the patterned light sources, the un-patterned light sources, and the NIR light sources.

Devices, systems, and methods can be used to deliver photobiomodulation therapy (PBMT) to the GI tract. For example, this document describes battery-enabled LED light source devices that can be deployed through or over an endoscope and anchored directly to the GI tract. Significant systemic effects can be produced by PBMT with application to one part of the body promoting beneficial anti-inflammatory and metabolic benefits in other remote sites promoted by enhanced mitochondrial function and mitokine signaling.

A removable and replaceable sheath may be coupled to a medical instrument used during a procedure, and may enable one or more functional features of the medical instrument while maintaining a sterile barrier between the instrument itself and the treatment site. The sheath may be replaced prior to a subsequent use, and sterilization of the medical instrument is not required due to the sterile barrier. Sheaths may include an embedded memory that stores procedure configurations and procedure results, longitudinal channels for delivering power or irrigation, optical elements for providing procedure specific endoscopic views, and other features. One sheath may be fitted to an endoscope for imaging and tissue ablation. Another sheath includes a balloon usable during sinuplasty procedures. Yet another sheath may be fitted to a sonic ablation instrument to provide improved transmission of sonic power to tissue.

An endoscope includes a detachable wireless imaging device and an insertion tube having a distal end region. The attachment of the detachable wireless imaging device detachably attaches the detachable wireless imaging device to the distal end region of the insertion tube.

A medical capsule, comprising an enclosure, the enclosure comprising an opening at one end along an axial direction; a PCB group and a functional unit which are arranged inside the enclosure; wherein the PCB group comprises a plurality of PCBs which are connected through flexible printed circuits and are spaced from each other, and the functional unit comprises a battery unit electrically connected to the PCB; and a pressure detection unit, comprising a pressure transmission film assembled at the opening, a pressure sensor positioned in the enclosure, and a pressure collecting and processing circuit board electrically connected to the pressure sensor, wherein the pressure collecting and processing circuit board is connected to one of the PCBs through a flexible printed circuit. The medical capsule is simple in structure, easy to equip and allows for expansion of functions as needed.

Method for leveraging battery residue energy and a capsule endoscope using the method are disclosed. The capsule endoscope is capable of performing one or more functions at a first throughput or a first peak current when the battery has sufficient energy. According to this method, whether the battery energy is sufficient is determined. Upon determining the battery energy being insufficient, at least one function of the one or more functions is performed at a second throughput lower than the first throughput, or at least one function of the one or more functions is switched to another function requiring a second peak current lower than the first peak current
