A miniature single-photon fluorescence microscope implantation device and implantation method are disclosed. The implantation device includes: a clamp base defining a clamp slot; a clamp block; and a groove defined in a bottom surface of the clamp slot. An end of the clamp block includes a first protrusion, and a bottom surface of the groove vertically defines a through receiving hole.

Exemplary embodiments of a disposable endoscope are provided. For example, an endoscope is provided, including a tube having a proximal end and a distal end, a lumen having a proximal end and a distal end, the lumen surrounding an outer circumference of the tube, and a series of achromatic double lenses and singlet lenses within the tube from the distal end to the proximal end of the tube for conveying an image from the distal end of the tube to the proximal end of the tube. A housing is provided at the proximal end of the tube to provide a light path from the proximal end of the lumen to the distal end of the lumen from a polymer fiber optic located within the housing. A camera interface can be provided at an opposite end of the housing to receive the image from the distal end of the tube.

An optical endoluminal far-field microscopic imaging catheter comprises a light generating system, a first light delivery conduit for propagating light generated by the light generating system and a light distributor configured to redirect light propagated by the delivery conduit into a direction of an object to be imaged. A discriminator is configured for capturing light reflected from the object incident on a window of the discriminator from a particular direction and transmitting only the light captured from the particular direction to a second light delivery conduit. A drive mechanism is configured to sweep the window through a plurality of directions in a predictable pattern for matching each light capture event in the window with a direction of the window during the event. An analyzer matches the direction of the window with an associated light capture event and generate a visible image based on a mosaic of the captured light.

The present disclosure relates to an optical system, an endoscope, and a medical image processing system capable of adjusting an effect of extending a depth of field.

A medical image processing system includes: a light source that irradiates an observation target with light; an image capturing control unit that controls capturing of an image of the observation target irradiated with the light; and an endoscope including a scope having a tubular shape and made from a rigid or flexible material, a camera head including an imaging element that captures an image, and an optical element insertion unit provided between the scope and the camera head. Further, the optical element insertion unit includes two or more optical elements having the effect of extending the depth of field, and at least one of the optical elements is movable. The present technology is applicable to, for example, a medical image processing system including an EDOF optical system.

A rigid scope includes: an objective lens composed of, in order from an object side to an image side, a first lens group having a negative power, a second lens group including a lens having a positive power, and a third lens group including two or more lenses; a relay lens arranged on the image side of the objective lens; a first lens frame that fixes in place a front group including at least the first lens group and the second lens group of the objective lens; and a second lens frame that fixes in place a rear group including one or more remaining lenses constituting the objective lens and at least part of the relay lens.

An imaging scope includes an internal surface defining an internal cavity, a window permitting visual inspection of the internal cavity, a fluid in the internal cavity having a pressure different than ambient pressure, and a leak indicator transitionable between nonvisible and visible through the window when the pressure of the fluid changes toward ambient pressure.

A surgical instrument is inserted through a guide tube. The surgical instrument exits at an intermediate position of the guide tube and is oriented to be substantially parallel to the guide tube's longitudinal axis as it exits. A stereoscopic image capture component is on the guide tube between the intermediate position and the guide tube's distal end. The image capture component's field of view is generally perpendicular to the guide tube's longitudinal axis. The guide tube is jointed to allow the image capture component to be moved. The surgical instruments and the guide tube are telemanipulatively controlled.
