An image calibration inspection tool includes: a plurality of substantially rectangular markers, two orthogonal sides of which are connected by an arc-shaped curve; and a calibration chart in which the plurality of markers are formed on a metal plate through machining, laser marking, or the like, wherein two of the markers in a diagonal direction are separated by a predetermined distance.

An adjustable endoscope fixing device, comprises a tail bed, a three-way connector and a locking screw; an outer wall surface of a straight column section of the tail bed is provided with a rectangular slot; and an outer wall surface of a first connecting end of the three-way connector is provided with a locking structure, and the straight column section of the tail bed is connected to the first connecting end of the three-way connector, and the tail bed is fixed to the three-way connector by the locking structure.

An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.

An insertion unit for a detachable endoscope, the insertion unit including a housing having a hollow formed penetrating both ends of the housing but being isolated from an outside of the housing; a first intermediate connection part inserted into an inside of the housing to penetrate the both ends of the housing; and a second intermediate connection part spaced apart from the first intermediate connection part and inserted penetrating the hollow.

An enhanced flexible robotic endoscopy apparatus includes a main body and flexible elongate shaft. The main body comprises a proximal end, a distal end and a housing that extends to the proximal end and the housing comprises a plurality of surfaces and a plurality of insertion inlets which reside on at least one of the surface of the housing at the proximal end of the main body, through which a plurality of channels for endoscopy are accessible. Each of the insertion inlets has insertion axis corresponding thereto, along which flexible elongate assemblies are insertable, with the insertion axes of the insertion inlets being parallel to the central axis of the flexible elongate shaft at the proximal end of the flexible elongate shaft.

An apparatus, system and process for identifying one or more different tissue types are described. The method may include applying a configuration to one or more programmable light sources of an imaging system, where the configuration is obtained from a machine learning model trained to distinguish between the one or more different tissue types captured in image data. The method may also include illuminating a scene with the configured one or more programmable light sources, and capturing image data that includes one or more types of tissue depicted in the image data. Furthermore, the method may include analyzing color information in the captured image data with the machine learning model to identify at least one of the one or more different tissue types in the image data, and rendering a visualization of the scene from the captured image data that visually differentiates tissue types in the visualization.

A sheath assembly is adapted for an ultrasonic probe and includes a plug portion and a sheath portion connected to each other. One end of the plug portion of the sheath assembly is used for detachably and fixedly connecting with a connecting butt joint portion of the ultrasonic probe, so that the plug portion and the connecting butt joint portion are detachable after the ultrasonic probe is used. An inside of the plug portion communicates with an inside of the sheath portion to receive a torque transmitting portion of the ultrasonic probe.

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.

An endoscope as an insertion device includes an insertion portion main body extended in a direction of a longitudinal axis and having flexibility, a motor provided in an operation portion disposed on a proximal end side of the insertion portion main body, a transmission member inserted into the insertion portion main body, extended outward the insertion portion main body along the longitudinal axis, rotated around an axis by driving force of the motor, and transmitting the rotation to a distal end side of the insertion portion main body, and a detection device detecting a position along the longitudinal axis of the insertion portion main body at a predetermined site of the transmission member.

An endoscope eyepiece grasping mechanism includes a base part engaging a tab member via a connected engagement member. An annular part has an outer engagement surface and an inner camming surface disposed coaxially with the base part and axially moveable relative to the base part. The engagement surface is moveable with the camming surface to move the tab member radially outwardly, with a movement of the annular part relative to the base part in a first axial direction, toward a receiving position, and to move the tab member radially inwardly, with movement of the annular part relative to the base part in a second axial direction, toward a grasping position. A biasing device acts to bias the annular part toward the grasping position. An endoscope eyepiece is engaged by the tab member upon the annular part moving from the receiving position to the grasping position.
