A rapid exchange detachable endoscope includes a transmission system having a shaft with two linear translation nuts mounted on oppositely threaded portions of the shaft so that rotation of the shaft in one direction moves the two linear translation nuts further away from one another and rotation of the shaft in an opposite direction moves the two linear translation nuts closer together to control an insertion tube tip. A control handle can be attached and detached from the transmission system, allowing an insertion tube associated with the transmission system to remain in vivo and allow for exchange of overtubes.

A flexible endoscope includes a disposable endoscope body structure and a reusable camera assembly. The endoscope body structure includes a handle portion, a flexible inserting portion, and a line connecting portion. The flexible inserting portion is directly or indirectly connected to the handle portion. The line connecting portion includes a receptacle located in the handle portion and an external connecting portion located outside the handle portion. The receptacle is directly or indirectly connected with the external connecting portion. The handle portion is provided with a camera assembly access port for the camera assembly to access. After accessing and being assembled to the camera assembly access port, the camera assembly access port is able to insert into the receptacle to transmit electrical energy and/or a signal with the external connecting portion with the receptacle. The flexible inserting portion is provided with an instrument for controlling the flexible inserting portion to bend, and the instrument is penetrated through the flexible inserting portion.

The present disclosure provides a mounting structure for an endoscope front-end piece, including a front-end piece, a pull rod, and an adjustment mechanism. The front-end piece includes a front end clamped onto a port of an endoscope tube, and a rear end extended into the endoscope tube; a sealant groove is formed in a portion of the front-end piece contacting an inner wall of the endoscope tube; the pull rod includes a front end connected to the front-end piece, and a rear end extended into an endoscope tube socket; and the adjustment mechanism is located in the endoscope tube socket, and is capable of both compressing the endoscope tube socket and tensioning the pull rod through threaded transmission, thereby allowing the front-end piece to retain on the port of the endoscope tube, and adjusting a mounting gap and a mounting pressure. The structure realizes gapless mounting of the front-end piece.

A steerable endoscope is provided with active steering control. An endoscope includes a flexible tubular body with first and second articulating segments, and a camera. In an embodiment, the endoscope includes an orientation sensor. A controller for the endoscope performs an automated analysis of an alignment between the motion axis of the endoscope and the viewing axis of the camera, and actively steers the endoscope to improve the alignment.

An inspection analysis method includes an analysis step, a prediction step, and an output step. A processor analyzes inspection information related to an operation in an inspection and generates first operation data and second operation data indicating a content of the operation in the analysis step. The first operation data indicate a content of the operation in a first inspection. The second operation data indicate a content of the operation in a second inspection performed after the first inspection is completed. The processor compares the first operation data and the second operation data with each other and predicts a state of an inspection target in the prediction step. The processor outputs state information indicating the state to a reporting device in the output step.

A tool comprises a distal portion and a proximal portion spaced apart by a shaft along a longitudinal axis. The distal portion includes a distal link and the proximal portion including a proximal link. The distal link and proximal link form a pair of links. The tool also comprises a set of tension load bearing members connecting the proximal link and the distal link and terminating at the links of the pair to transfer movement therebetween. The tool also comprises an articulation lock positioned between the distal portion and the proximal portion and configured to allow through passage of the set of tension load bearing members. The articulation lock is adjustable between an unlocked configuration in which the proximal and distal links are moveable and a locked configuration in which an effective length of the shaft is increased, creating a force to impede movement of the proximal and distal links.

A stylet assembly and method of forming an in vivo image acquiring stylet assembly. The stylet assembly includes an elongate flexible body and an image acquiring device that is supported at a location that is offset from an in vivo facing terminal end of the stylet assembly. A terminal end portion of the stylet assembly is defined by a manipulator that is oriented to extend in a crossing direction relative to a longitudinal axis of the elongate body. The terminal end portion of the stylet assembly is steerable relative to the elongate body and is operable to manipulate positions or adjacent anatomy and/or effectuate guidance of the imaging device relative thereto during use.

An endoscope (1) including a handle (2) arranged at a proximal end and an insertion tube (3) extending from said handle (2) towards a distal end, a bending section (7) arranged at the distal end and controllable by and operator via control input means (8) arranged at the handle (2); and at least one insertion tube part with at least one lumen, wherein the bending section (7) is displaceable in said lumen so as to be movable relative to the insertion tube (3) from a retracted position within said lumen to an extended position at least partially outside said lumen.

A medical device includes a handle including an actuating device, a shaft extending from the handle and having a longitudinal axis, a cam rotatably connected to the handle, wherein the cam includes a first section and a second section, and wherein a distance between a radially outer surface of the first section and a center of the cam is different from a distance between a radially outer surface of the second section and the center of the cam; and an actuation wire extending from the cam to a distal end of the shaft. Rotation of the actuating device rotates the cam, causing the actuating wire to wrap around the first section and the second section to deflect the distal end of the shaft.
