An endomicroscopic device, which, in microsurgical operations, enables the deep surgical sites that cannot be seen from a certain angle to become visible. The endomicroscopic device includes a light source to illuminate the surgical site, a microscope lens for taking and magnifying an image of a tissue at the surgical site, a pair of binocular eyepieces for projecting the image to eyes of the surgeon, an endoscopic probe for displaying blind areas outside of a field of view of the at least one microscope lens from different angles in a periscopic manner, an endoscopic probe outlet, and a distal portion located at an end of the endoscopic probe. The distal portion is flexible and can be angled to be directed to different areas, and provides a second periscopic image.

Disclosed is a method of unilateral biportal endoscopy and a surgical instrument set used in the same. More particularly, the present invention relates to a method of unilateral biportal endoscopy which separately secures a working portal for surgical instruments and an endoscopic portal for an endoscope, thereby providing a more accurate spinal surgery, and to a surgical instrument set which can be effectively applied to the method.

Provided are a miniature endoscopic probe and a multi-photon endoscopy including the same.

An otoscope that utilizes ambient light is disclosed. The otoscope includes a fiberoptic cable(s), as opposed to batteries, to illuminate the inspection area. The otoscope made of non-metallic and/or non-ferrous materials to permit its safe use in highly flammable oxygen or magnetic environments. The otoscope includes a handle, a head coupled to the handle, and a specula coupled to the head. An eye piece coupled to the head opposite the specula. A reflective lens is positioned within the head. A fiber optic cable is positioned within the handle. The handle includes a first end positioned opposite a second end. The head is coupled to the first end. The fiber optic cable provides light to the reflective lens. The fiber optic cable extends from the front end to the second end. The reflective lens is oriented to reflect light to the specula.

The present disclosure relates to an endotherapy camera coupler. The coupler may detachably couple an endotherapy eyepiece cap to a camera and may support a drape for covering the camera. In one example, the coupler comprises an optically transmissible and liquid impermeable member configured to be arranged in an optical path between the eyepiece cap and the camera, a base holding the optically transmissible and liquid impermeable member in the optical path, a receiving portion for the eyepiece cap, wherein the receiving portion comprises a base-side receiving portion configured to receive the eyepiece cap along an insertion path extending in one direction, and a liquid barrier provided in the receiving portion and configured for hindering or preventing liquid from entering between the eyepiece cap and the optically transmissible and liquid impermeable member when the eyepiece cap is coupled to the camera. Other examples of devices and methods of use are described.

Medical borescopes and related methods. In some embodiments, a medical borescope may comprise a handle and a tube extending from the handle. The tube may be partially, or wholly, defined by an at least substantially non-conductive material, such as a suitable plastic, ceramic, or other non-metallic material. The borescope may further comprise a tip assembly positioned at a distal end of the tube, which may comprise an image sensor configured to take images through the distal end of the tube.

A portable endoscopic inspection system comprises an endoscope having a proximal end with a flanged eyepiece for observation and a distal end with a lens assembly for insertion into a region of interest. A light port transports incident light to the region of interest along an lighting pathway, and reflected light is transported along an imaging pathway from the lens assembly to the eyepiece. A wireless imaging unit comprises a light source which detachably couples to the light port for generating the incident light, and an imaging sensor for recording images of the reflected light from the eyepiece. The wireless imaging unit comprises a variable coupling system which mechanically couples the imaging sensor to the flanged eyepiece independent of the shape and/or size of the flange of the eyepiece.

An endoscope camera head 6 includes a first and a second members 8, 9 that are relatively rotatable about a first axis Ax1. The first member 8 has a first rotation-sliding surface 84 that extends in an annular shape about the first axis Ax1 as its center. The second member 9 has a second rotation-sliding surface 93 that engages with the first rotation-sliding surface 84 in a state in which movement to a direction of the first axis Ax1 relative to the first member 8 is restricted, and that rotation-slides relative to the first rotation-sliding surface 84 about the first axis Ax1. The second rotation-sliding surface 93 abuts only on a part of the first rotation-sliding surface 84, to expose a part of the first rotation-sliding surface 84 outside.

The otoscope made of non-metallic and/or non-ferrous materials to permit its safe use in highly flammable oxygen or magnetic environments. The otoscope includes a handle, a head coupled to the handle, and a specula coupled to the head. An eye piece coupled to the head opposite the specula. A reflective lens is positioned within the head. A fiber optic cable is positioned within the handle. The handle includes a first end positioned opposite a second end. The head is coupled to the first end. The fiber optic cable provides light to the reflective lens. The fiber optic cable extends from the front end to the second end. The reflective lens is oriented to reflect light to the specula.

An optical system for a stereo-video endoscope, the optical system including: first and second lens system channels having first and second optical elements on first and second optical axes, respectively, the first and second optical axes being parallel to each other; wherein the first and second optical elements are each arranged symmetrically relative to each other about a plane of symmetry between the first and second lens system channels and the first and second optical elements comprise first and second D-cut lenses, respectively, each of the first and second D-cut lenses having a boundary surface which is set back relative to the plane of symmetry; and the boundary surface of each of the first and second D-cut lenses are inclined with respect of the plane of symmetry.
