A medical instrument includes a first elongated member including: a fluid lumen through which a fluid is flowable, an aperture opening located in a distal end surface of the first elongated member; a second elongated member including: an insertion lumen in which the first elongated member is insertable, and a discharge section through which the fluid can be discharged; and a movement section configured to form a seal between the first elongated member and the second elongated member in a state where the first elongated member is disposed in the insertion lumen of the second elongated member, the movement section being configured to allow the first elongated member and the second elongated member to move relative to each other such that the discharge section of the second elongated member is positionable on a distal side of the aperture of the first elongated member.

A laryngoscope with a handle, at the distal end of which a blade is arranged at an angle to the longitudinal axis of the handle, wherein a channel for receiving an image carrier of a video endoscope is formed in the handle and in the blade such that the channel, in a transition area from the handle to the blade, merges in a radius from the handle into the blade. In order to provide a laryngoscope which, while being easy to handle, ensures insertion of the image carrier into the channel in a way that protects material, in the transition area from the handle into the blade, at least one run-on bevel is formed in the interior of the channel.

Disclosed herein are intestine pleating methods and devices for use with gastrointestinal endoscopes. Devices include balloon access device, attachable structure(s), and an elongate overtube. Attachable structures may be used to pleat intestinal wall and to advance the endoscope past difficult to navigate areas. Balloon access device may be used to improve visualization of intestinal wall and to pleat intestinal wall. These systems may be used during airless endoscopic procedures that do not require insufflation of the intestinal cavity. The systems may be used during airless intubation procedures. To pleat the intestine, the practitioner inflates balloon to a fully or nearly fully inflated state when a difficult area is encountered. Inflation of the balloon to fully or nearly fully inflated state ensures contact with intestinal wall. Practitioner pulls back on the endoscope shaft to drag intestinal wall back toward the proximal opening of intestinal cavity. Pleating facilitates forward advancement of endoscope.

An insertion device includes: a tube having a channel hole and a communication hole; a frame member having a tube insertion hole and a forceps channel and disposed to cover a periphery of the communication hole; and a closing member configured to close the channel hole in the tube at a position closer to a proximal end side than the communication hole and having a distal end surface disposed to face the communication hole.

Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

According to the present invention, there is provided an endoscopy system comprising an endoscope guide and an endoscope. The endoscope of the system comprises a proximal end and a distal end. The endoscope guide of the system comprises a proximal end, a mid-section comprising at least one endoscope entry port, a distal end comprising at least one endoscope exit port, a lumen capable of receiving an endoscope extending from the at least one entry port to the at least one exit port and at least one bend located between the at least one entry port and the at least one exit port. The endoscope guide is capable of directing the insertion of the distal end of the endoscope into a body cavity when the distal end of the endoscope exits the endoscope exit port and the distal end of the endoscope guide is also configured so as to be capable to be retained within the body cavity during a surgical procedure so as to control the positioning of the distal end of the endoscope within the body cavity.

A compact single-axis confocal endomicroscope is provided, capable of complying within 2.8 mm diameter endoscope space requirements. The single-axis confocal endomicroscope uses a folded path design achieved between a fixed mirror and a lateral plane scanning mirror thereby producing a high numerical aperture that allows for diffraction-limited resolution with sub-surface depths. The scanning mirror is formed on a fixed-position, scanning MEMS assembly and has a central aperture that allows for illumination beam expansion in the folded path design. A series of spacers are used to retain beam focusing optical elements in fixed positioned relative to the scanning MEMS assembly for coupling with a single mode fiber.

An endoscope includes a first pulling section, an first elongated member, a restricting portion, a sliding surface, and a partition. The restricting portion is provided inside the operation section, and is configured to restrict a position of the first pulling section. The sliding surface is provided in the restricting portion, and allows the first pulling section to move along the axial direction. The partition covers at least a part of the sliding surface and the first pulling section, and is configured to partition the first elongated member and the first pulling section. The partition and the restricting portion are configured to restrict a moving range of the connection portion within a range of the sliding surface.

A multi-plane sleep monitoring endoscope includes an observation system, a data processing and outputting system, a lighting system, a display system, a circuit, a shell, and a power system. The observation system is a photographing system and includes two sets of imaging systems; distal ends of the imaging systems form observation ends, and the observation ends are not on the same horizontal plane. A positioning system can adjust a distance L between the horizontal planes where the observation ends are located and spatial states of the observation ends. The at least two sets of imaging systems can simultaneously perform observation and display on the display system. The multi-plane sleep monitoring endoscope can simultaneously monitor different planes in the sleep process of an obstructive sleep apnea/hypopnea syndrome patient, particularly suitable for simultaneously monitoring the velopharyngeal plane and the glossopharyngeal plane, and is safe and efficient in the clinical use process.

A probe part (100) includes abase member (110) defining a first bore (112). A first elongated elastic member (120) includes a near end (126) secured to the base member (110) and extends therefrom to a far end (128) and defines a channel (125) in communication with the first bore (112) and that runs lengthwise with the first elongated elastic member (120). A first tendon (130) has a first end and an opposite second end that is secured to the first elongated elastic member (120) adjacent to the far end (128). The first tendon (130) mns through the channel (125) adjacent the first side (122) and exits through the first bore (112) exiting outwardly therefrom. Applying tension to the first tendon (130) causes the first elongated elastic member (120) to bend in the direction of the first side (122).
