The disclosure relates to diagnostic, surgical, and/or therapeutic devices for being introduced into the human or animal body or for in vitro examination of human or animal blood samples or other body cells, in particular to an endoscope or a disposable endoscope that includes at least one illumination light guide and/or image guide for transmitting electromagnetic radiation, the illumination light guide or image guide having a proximal end face for incoupling or outcoupling of electromagnetic radiation and a distal end face for incoupling or outcoupling of electromagnetic radiation. The proximal and/or distal end faces consist of plastic elements that are transparent at least partially or in sections thereof, the transparent plastic being biocompatible and/or having non-toxic properties to human or animal cell cultures for exposure durations of less than one day. This allows for the production of assemblies for disposable endoscopes, inter alia.

The present disclosure provides systems and methods for medical imaging. The system may comprise a scope assembly. The scope assembly may comprise a housing unit configured to releasably couple to at least a portion of an elongated scope. The scope assembly may comprise an imaging unit operably coupled to the housing unit, wherein the imaging unit comprises an optics assembly configured to (i) receive one or more light beams that are transmitted through the elongated scope and (ii) direct at least a portion of the one or more light beams onto two or more locations within a subject's body. At least one of the two or more locations may comprise a target site. The imaging unit may be configured to move via a rotational and/or translational motion relative to the housing unit to alter a field of view when imaging within the subject's body.

An optical connecting device for a surgical instrument including a coupling for connecting first and second optical fiber bundles. The coupling including: a tubular sleeve having an outer surface defining an internal space for receiving an end of the first optical fiber bundle in the internal space of the tubular sleeve; a clamp movably disposed on the outer surface of the tubular sleeve, the clamp having one or more of a first convexity and a first concavity; and a union having one or more of a second convexity and a second concavity. The clamp has a continuous longitudinal opening along its longitudinal extension and on its outer side such that the clamp can be elastically deformed in a radial direction, and the clamp is configured to elastically deform such that one or more of the first convexity and the first concavity engages with one or more of the second convexity and the second concavity of the union.

An endoscope includes an insertion portion including a bending portion, an operation portion including an operation lever, a grasping portion including an actuator, and a tube body, in a continuous manner. When the operation lever is tilted, the actuator pulls a wire, whereby the bending portion is bent in a vertical direction and a lateral direction. The actuator is arranged such that a center of gravity of a portion including the insertion portion, the operation portion, the grasping portion, and the tube body is within a range in which at least one of the fourth finger or the fifth finger of the hand grasping the grasping portion is positioned, in a longitudinal direction of the grasping portion.

An optical fibre having a functionalised distal exploration end including a sheath, and a ferrule rigidly connected to the sheath at the distal exploration end, characterised in that the distal exploration end has a functionalised head which is removably attached on the ferrule. Also, a method of assembling the optical fibre.

A video endoscope, in particular a video mediastinoscope, comprises an elongate rigid shaft and a handle detachably attached to a proximal end section of the shaft, wherein the shaft comprises an optics shaft comprising an imaging optics and an electronic image sensor, wherein the optics shaft and a plug connector housing arranged at a proximal end of the optics shaft form a hermetically sealed unit enclosing the imaging optics and the image sensor, and wherein the handle comprises a handle housing in which an electronics unit is accommodated, wherein the electronics unit is hermetically sealed. The invention also relates to a method for configuring a video endoscope.

A surgical visualization feedback system is disclosed. The surgical visualization feedback system comprises an emitter assembly configured to emit electromagnetic radiation toward an anatomical structure. The emitter assembly comprises a structured light emitter configured to emit a structured light pattern on a surface of the anatomical structure and a spectral light emitter configured to emit spectral light capable of penetrating the anatomical structure. The surgical visualization feedback system further comprises a waveform sensor assembly configured to detect reflected electromagnetic radiation corresponding to the emitted electromagnetic radiation and a control circuit in signal communication with the waveform sensor assembly. The control circuit is configured to receive an input corresponding to a selected surgical procedure, determine an identity of a targeted structure within the anatomical structure based on the selected surgical procedure and the reflected electromagnetic radiation, and confirm the determined identity of the targeted structure through a user input.

An endoscope includes an insertion unit, an operation unit, an emission end, a first light guide and a second light guide that guide illumination light emitted from a light source unit to the emission end, a lens member that suppresses a variation in a relative intensity of each color light of the illumination light, and a connection unit that optically connects the first light guide, the second light guide, and the lens member; and the lens member is disposed between the first light guide and the second light guide, and the connection unit and the lens member are provided in the operation unit.

Surgical systems are provided. In one exemplary embodiment, a surgical system includes a first scope device having a first portion within an extraluminal space and a second portion positioned within an intraluminal space. The first scope device transmits image data of a first scene. A second scope device is disposed within the extraluminal space and transmits image data of a second scene. The first portion of the first instrument is present within the field of view of the second scope device to track the first scope device relative to the second scope device. A controller receives the transmitted image data of the first and second scenes, to determine a relative distance from the first scope device to the second scope device within the extraluminal space, and to provide a merged image. At least one of the first and second scope device in the merged image is a representative depiction thereof.

In general, devices, systems, and methods for multi-source imaging are provided.
