A disposable uterine endoscope relates to the technical field of medical instruments. The disposable uterine endoscope includes a handle mechanism and an intubation mechanism. The intubation mechanism includes a rotary inner tube and a supporting outer tube. One end of the rotary inner tube is rotatably connected with the handle mechanism and the other end of the rotary inner tube is connected with a camera. The supporting outer tube is sleeved in a circumferential direction of the rotary inner tube, one end of the supporting outer tube is fixedly connected with the handle mechanism and the other end of the supporting outer tube is provided with a bent section, the bent section is provided with a continuous bent groove, and the bent groove is arranged spirally along the circumferential direction of the bent section.

An endoscope system includes a light source that emits illumination light, an image sensor that captures an image of an object toward which the illumination light is emitted, and a processor. The processor is configured to determine whether a fluid is present in the object. If the fluid is not present in the object, the processor switches to a first observation mode in which to illuminate the object by first illumination light. If the fluid is present in the object, the processor switches to a second observation mode in which to illuminate the object by second illumination light. The second illumination light includes is larger than the first illumination light in a relative ratio of long wavelength components.

An endoscope that includes an elongated bougie, a distal tip at a distal end of the bougie and a handle at a proximal end of the bougie. The distal tip has a camera, an LED light, and a distal tip housing forming a distal tip chamber. The endoscope also has an electronic connector, such as a PCB board connector, having at least one PCB board, and at least a portion of the PCB board is nestled within the distal tip chamber. The PCB board connector is disposed between the distal tip and the distal end of the elongated bougie when being assembled. The distal tip and the PCB board connector are attached into one integral distal assembly by removable attaching means, such as a pair of snap fit hood and holder. The integral distal end assembly is configured to be cut from the old bougie used in a medical procedure and to be collected and later disassembled, sterilized, and reassembled with another new bougie.

A medical image processing apparatus includes an image processor configured to: receive a plurality of first image data captured at different times and generated by illumination of light in a first wavelength band in sequence; receive a plurality of second image data captured at different times and generated by illumination of light in a second wavelength band different from the first wavelength band in sequence; generate first and second images based on the received first and second image data, respectively; and output the generated first image and second image to a display in chronological order of the first and second images and in accordance with a preset display pattern of the first and second images.

A medical imaging system is described that comprises an heating element configured to apply at least one heating pattern element to a material to locally heat the material; a sensor configured to capture the position of the heated material a predetermined time after the application of the heating pattern element; and circuitry configured to determine the change of the heating pattern applied to the material based upon the captured position of the heated material after the predetermined time.

A method for manufacturing an endoscope having a tip housing may comprise the steps of moulding at least one tip housing for an endoscope by injection moulding or by multi shot injection moulding. Each tip housing may comprise an integrally formed wall defining an interior cavity and a proximal opening providing access to the interior cavity. The wall may comprise a longitudinally extending side wall portion, a distal end wall portion, and a window portion. The window portion may consist essentially of a transparent first material and form part of the side wall portion and/or the distal end wall portion. The wall may further comprise a wall surface facing the exterior of the tip housing and having a window surface of the window portion and a distally facing end surface of the distal end wall portion. The method may further comprise positioning the at least one tip housing in a treatment chamber; and applying, in the treatment chamber, a treatment formulation to provide a coating on at least the wall surface.

A novel in-vivo image capture device for capsule endoscope and its method of operation are described. The device includes a wafer level camera module design, high sensitivity backside illumination pixel with high definition image output and LED's to provide illumination, which is synchronized with an image sensor strobe signal. A frame rate of the device can be adjusted based on an angular motion detection from a gyroscope sensor, in which a high frame rate mode is maintained during fast motion while a low frame rate is maintained during slow or no motion. The image capture device also includes machine learning based SOC for image processing, enhancement, and compression. The SOC can process and store zone average of images. The image capture device also includes a high density flash storage to store images in the device, thus no RF transmitter is needed, which make the system more convenient to use.

A medical tool includes, a deflectable distal end, at least a pull wire, and a deflection assembly. The at least pull wire having a first end coupled to the distal end of the medical tool and configured to be moved for deflecting the distal end. The deflection assembly is coupled to a second end of at least the pull wire and is configured to control a deflection of the distal end. The deflection assembly includes a first gear having a first rotation axis, and a second gear, having a second rotation axis and including a jagged surface for integrating with the first gear. The jagged surface is slanted relative to the second rotation axis, and when the first gear rotates, the second gear is configured to be rotated by the first gear, to move along the second rotation axis and to deflect the distal end by moving the pull wire.

Endoscopes of this disclosure, such as colonoscopes, provide a broader field of view and allow extended access of surgical tools, and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Methods and systems of this disclosure include for capturing and displaying still and video images using an endoscope corresponding to a left-side looking viewing element, a front-looking viewing element, and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

A deployable and flexible tooltip camera is provided for integration within a shaft of an endoscopic tool. The tooltip camera includes a camera mounted to a distal tip of a curved tube which is capable of rotational and translational movement to provide a wide field of view of a tooltip of the endoscopic tool during an endoscopic procedure. The tube retains its curved shape when in use to provide a unique perspective view of the tooltip, but can then be withdrawn into a shaft of the endoscopic tool such that the entire tooltip camera and tube are retained within the shaft of the endoscopic tool and can pass through a cannula. The curved tube may be formed of a super-elastic memory alloy like Nitinol and pre-shaped into an s-curve using a two-step heat treatment process to attain the necessary curvature, and further laser-patterned with holes to attain the necessary flexibility.
