Disclosed is an elongated shaft detachably mountable on a reusable handle of a multi-camera endoscope, The elongated shaft includes a shaft body. The shaft body includes, at a shaft body distal section, at least two cameras and at least one illumination component, and, at a shaft body proximal section, an adaptor. The adaptor is configured to mechanically and electronically detachably couple to a coupling interface on a distal section of the handle, such as to mount the elongated shaft on the handle. The adaptor is further configured to dictate a preferred mounting orientation such that the at least two cameras provide a combined and predetermined at least about 270 degrees horizontal field-of-view (FOV) of a target area within an anatomical cavity when the elongated shaft is mounted on the handle.

A method of operating a manipulator arm comprising a manipulator interface configured to removably couple with and transmit actuation force to a medical instrument includes mounting a cannula to a cannula mount coupled to the manipulator arm; mounting a medical instrument to the manipulator interface; inserting a shaft of the medical instrument through an entry guide mounted to the cannula; rotating the manipulator interface and the medical instrument relative to the cannula mount; and rotating the entry guide relative to the cannula mount about a longitudinal axis of the cannula.

A housing (1) for the tip of a disposable insertion endoscope includes a circumferential side wall (2) having a first end and a second end, and a front wall (3) arranged at the first end to provide an internal compartment (4) in the housing (1), the front wall (3) including at least one transparent part made of a polymer material and adapted to protect a camera (10) arranged in the housing behind the at least one transparent part and a front surface (15) having at least one area provided with a nano-structure.

Embodiments of the present invention are directed to providing an effective and reliable approach for cleaning an exposed surface of an imaging element (e.g., a lens) of apparatuses including but not limited to medical imaging instruments such as endoscopes and laparoscopes and the like. In the case of medical imaging instruments, cleaning apparatuses configured in accordance with embodiments the present invention can be cleaned while the distal end portion of the endoscope is in vivo. Such apparatuses have a cleaning member incorporated therein (e.g., a resilient polymeric wiper, a sponge, an absorbent pad or the like) that is used for cleaning the exposed surface of the imaging element. The apparatus is preferably adapted for being mounted on imaging apparatus but can also be entirely or partially integral with one or more components of the imaging apparatus or system of which it is a component.

An endoscope clip including; first and second jaws pivotally connected together for movement between open and closed positions, and a spring biasing the first and second jaws into the closed position, wherein each of the first and second jaws comprise: a tube engaging portion, wherein opposing pairs of tube engaging portions for the first and second jaws define two or more adjacent channels configured to receive a portion of an endoscope tube, wherein each of the two or more adjacent channels has an arcuate longitudinal axis; and an actuation portion operable by a user to overcome the biasing action of the spring to open the first and second jaws.

An endoscope includes a distal-end hard portion at a distal end of an insert, including a body, housing, first and second grooves in the body to extend inwardly, and a through-hole communicating the first and second grooves in the housing; a forceps-raising table in the first groove, including a fitting-groove along a through-hole extending direction; an arm portion including a pillar extending from the second groove to the first groove, a fit-in portion fitted in the fitting-groove on one side, and a connecting portion on the other side, the connecting portion being connected with a forceps-operating wire; and a seal portion on a periphery of the pillar, sealing water-tightly a first gap and a second gap, the first gap being between a periphery of the pillar and a periphery defining the through-hole, and the second gap being between the periphery of the pillar and a periphery defining the fitting-groove.

According to the present invention, there is provided an endoscopy system comprising an endoscope guide and an endoscope. The endoscope of the system comprises a proximal end and a distal end. The endoscope guide of the system comprises a proximal end, a mid-section comprising at least one endoscope entry port, a distal end comprising at least one endoscope exit port, a lumen capable of receiving an endoscope extending from the at least one entry port to the at least one exit port and at least one bend located between the at least one entry port and the at least one exit port. The endoscope guide is capable of directing the insertion of the distal end of the endoscope into a body cavity when the distal end of the endoscope exits the endoscope exit port and the distal end of the endoscope guide is also configured so as to be capable to be retained within the body cavity during a surgical procedure so as to control the positioning of the distal end of the endoscope within the body cavity.

Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve, that authenticate the sleeve for use with an intraoral scanning system. Authentication may include verifying that the sleeve is new (unused) and/or verifying that the sleeve is appropriate and/or intended for use with the intraoral scanning system. Once authenticated, operation parameters of the intraoral scanning system can be automatically set based on information from a scanned identifier on the sleeve.
