In some embodiments, an electronic laryngoscope includes a camera, a hollow connecting rod, a handle, and a control display. The front end of the connecting rod is connected to the camera, the rear end of the connecting rod is connected to the handle, and the rear end of the handle is connected to the control display. The laryngoscope further includes a hollow tube whose inner diameter is greater than the outer diameter of the connecting rod. The camera and the connecting rod are located on the inner side of the hollow tube. A sputum suction opening is formed between the front end of the hollow tube and the front end of the camera, and a sputum passage in communication with the opening is formed between the hollow tube and the connecting rod. The laryngoscope further includes a connector between the hollow tube and the camera and/or the connecting rod.

A flexible tube used as a part of an insertion section which defines a central axis of an insertion apparatus to be inserted into a hole, the flexible tube includes: a helical tube comprising a closely-wound region including a concave-convex portion which is provided on each of a pair of edges of a strip-shaped member elongated along a longitudinal axis, and which alternately includes convex portions and concave portions on the concave-convex portion, wherein, in a state where the strip-shaped member is spirally wound, the convex portions of the concave-convex portions facing each other along the central axis are compressed to each other; and a cylindrical outer tube which covers an outer surface of the helical tube.

An endoscopic instrument (1, 134), for inserting into a body of a patient, includes a tubular shank (3, 47, 137) which is coupled or can be coupled to a handling device (5, 135), and at least two electrical, mechanical and/or optical leads (11, 13, 15, 19, 57, 59, 65, 67, 123, 181) which run through the shank (3, 47, 137). The handling device (5, 135) includes a housing (23) which at a proximal end has two limbs (141, 143) which are arranged obliquely to one another and enclose a contact surface (145). At least one of the leads (11, 13, 15, 19, 57, 59, 65, 67, 123, 181) is led outwards out of the handling device (5, 125) out of one of the limbs (141, 143).

An endoscope, which is provided with an observation optical system provided at the tip of an insertion portion and a connecting pipe portion for sending a fluid onto the observation optical system side, includes a small diameter portion which has one end opening to which a fluid from the connecting pipe portion flows and has a diameter smaller than the connecting pipe portion, a lid portion which covers the other end opening of the small diameter portion, and a guide wall which is provided inside the lid portion to be separated from an edge of the other end opening in a radial direction of the other end opening and guides the fluid from the small diameter portion to an outlet.

Embodiments of the present invention provide water bottle cap assemblies suitable for attachment to an endoscopic device and a water source. The water bottle cap assembly can include a plurality of ports and an engageable member to sealingly engage the cap with a water source. The assembly also includes a plurality of tubular members, each tubular member coupled to a respective port so as to be in fluid communication therewith. The assembly can include a cap having a grippable surface that is overmolded onto the cap. The cap can also have a soft inner seal on the interior surface, and the soft inner seal can be integrally formed with the overmolded grippable surface. The cap can have a top that is pressfit onto the main portion of the cap. The grippable surface material can be overmolded over the top of the cap.

An endoscope includes a shaft assembly having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft assembly, and an elastomeric body housing an image sensor and at least one LED is comprises a distal end of the shaft. The elastomeric body is deformable between a repose straight insertion profile and a deflected offset profile by the insertion of a tool shaft through the shaft assembly and an expandable-collapsible working channel in the elastomeric body. The viewing angle of the image sensor is moved from a first selected angle to a second selected angle when the elastomeric body is actuated from the repose profile to the deflected offset profile.

This disclosure relates generally to medical tubing assemblies and methods for fluid delivery from a single fluid reservoir. In one example, a tubing assembly may be configured to couple to an endoscope for distributing fluid between the endoscope and a fluid reservoir during an endoscopic procedure. The assembly may comprise a tubing manifold, a cap configured to be removably attached to the fluid reservoir, a portion of gas supply tubing and lens wash supply tubing in fluid communication between the manifold and the endoscope, a portion of gas supply tubing in fluid communication between the cap and the manifold, and a portion of lens wash supply tubing in fluid communication between the fluid reservoir and the manifold. Further examples may include portions of irrigation supply tubing and portions of alternate gas supply tubing selectively connectable in fluid communication between the manifold, fluid reservoir and endoscope.

An improved flexible endoscopic instrument to precisely and efficiently obtains samples of flat polyps and multiple polyps from a patient by debriding one or more polyps and retrieving the debrided polyps without having to alternate between using a separate cutting tool and a separate sample retrieving tool and may be used with an endoscope. In one aspect, the cutting tool is coupled to a flexible torque coil or torque rope that is configured to transfer rotational energy from a powered actuator through the length of the endoscope onto the cutting tool.

An in-vivo camera device and an in-vivo monitoring camera system more excellent in usability are proposed. An in-vivo camera device includes a camera unit introduced into a body, a support member, and a camera-side cable. The support member has a trocar connection portion for connection with a trocar at a front end side, and is connected to the trocar in a state in which the trocar connection portion is fitted into the trocar by applying tensile force to the camera-side cable passing through the trocar. The support member is provided with a guide introduction portion that is formed to be relatively long at the front end side as a stabilization structure for stabilizing connection with the trocar.

An endoscopic system includes a single-use portion and a multiple-use portion. The two portions can be mated and un-mated. The single-use portion includes an elongated cannula that has a bendable section near its distal end providing a “steerable” distal tip. The distal tip includes LED illumination and an imaging module that feeds live video to a display screen forming which forms part of the multiple-use portion. Ergonomically designed steering control and significant portions of the steering structure reside in the multiple-use portion. The cannula is configured to rotate, which further expands the field of view when combined with steering deflection along a single axis. Some embodiments, include motorized distal tip deflection and/or omni-directional tip deflection.
