A sterile unit for the sterile connection of an instrument drive unit to a surgical instrument, including: a base with a circular passageway orifice having a transmission element supported to be rotatable around a rotational axis and axially movable in a direction of the rotational axis in a movement range between first and second end positions. The sterile unit also includes a first fastening mechanism connecting the sterile unit to the instrument drive unit and a second fastening mechanism connecting the sterile unit to the instrument. To improve the coupling between the sterile and instrument drive units, the transmission element has a conical region at a circumferential surface and the passageway orifice has a complementary conical region at a passageway wall. The conical regions are aligned coaxially and contact one another such that a rotation of the transmission element around the rotational axis relative to the base is blocked.

An endoscope accessory, such as a coupler device, is provided that includes a main body with a visualization section for allowing viewing of tissue by the endoscope and a proximal end configured for attachment to a distal end portion of the endoscope. The device includes a passage within the main body having an exit portal and a proximal end aligned with the working channel of the endoscope. An instrument passing through the passage is capable of angular adjustment relative to the main body of the coupler device by actuation of the endoscope.

An endoscope for the minimal invasive examination or surgical treatment of a patient has a flexible tubular shaft for insertion into the patient, a grip attached to a proximal end of the shaft for holding the endoscope, and at least one hollow tube. The shaft has at least one groove extending axially along an outer face of the shaft and in which the tube is removably housed. The tube has at least one working channel for guiding a surgical instrument, and/or carrying water or air to or providing suction at the shaft distal end. The shaft groove and the tube are dimensioned relative one another such that at least one free section of the tube is afforded play in the groove. In the straight extended state of the shaft, the at least one free section has an exterior cross-section which is slightly smaller than an interior cross-section of the groove.

Provided is a laryngeal mask airway, comprising a laryngeal mask airway main body (10) and a view device (20). The laryngeal mask airway main body (10) comprises a catheter (12), and a sealing base (13) connected to the distal end of the catheter (12), and the view device (20) comprises a control part (22) and a vidicon (23), wherein an image sensor (231) is formed at the distal end of the vidicon (23), and an air guide channel (101) and a view lumen (103) are formed in the laryngeal mask airway main body (10); and a first blind end part (103a) that is closed by a light-transmitting material is formed at the distal end of the view lumen (103), the vidicon (23) is inserted into the view lumen (103) in a pluggable manner, the distal end of the view lumen (103) and the distal end of the vidicon (23) extend into the sealing base (13), and the distal end of the vidicon (23) can be bent and reset. The vidicon (23) is sealed inside the view lumen (103) and does not come into contact with internal tissue of a patient during use, such that the vidicon (23) can be reused in a relatively safe manner; and the distal end of the vidicon (23) can bypass the epiglottis, and the drooping epiglottis can be pushed aside by means of controlling the distal end of the vidicon (23) to be bent upwards so as to obtain a good view.

A surgical instrument includes a proximal control mechanism. The proximal control mechanism has an opening through which a resilient latch arm can be inserted to engage a locking surface of a fixed latch structure contained within the proximal control mechanism. The resilient latch arm is contained entirely within the proximal control mechanism when engaged. A release channel extends from an outer periphery of the proximal control mechanism to the resilient latch arm entrance opening. The release channel provides a passage through which a release tool can be inserted to engage the resilient latch arm and provides a fulcrum for the release tool where the release channel is joined to the outer periphery of the proximal control mechanism. The surgical instrument can be released by prying the resilient latch arm away from the locking surface of the fixed latch structure with the release tool used as a lever on the fulcrum.

A rigid endoscope device comprises a disposable endoscope body structure (2), a disposable antibacterial line mechanism (3) and a reusable camera mechanism (1). A light source (5) is provided near the front end of the endoscope body structure (2). The endoscope body structure (2) is integrated with or separated from the antibacterial line mechanism (3). The camera mechanism (1) can be linearly inserted into the endoscope body structure (2) from the rear end of the endoscope body structure (2). The antibacterial line mechanism (3) can be linearly connected to the rear end of the endoscope body structure (2) and seals at the rear end of the endoscope body structure (2), such that the camera mechanism (1) inside the endoscope body structure (2) is isolated from the outside. In the rigid endoscope device, a reusable camera mechanism (1) is isolated from the external environment and is not in contact with people, thereby effectively ensuring a sterile state thereof.

A pressure monitoring device used to monitor for leaks in a tool such as a medical endoscope. The device includes a housing having an internal volume fluidically coupled with an internal volume of the tool to form a combined internal volume. A pump changes the pressure inside the combined internal volume thereby establishing a baseline pressure at a pressure differential from the ambient environment. During operation of the tool, the pressure inside the combined internal volume is monitored for a change exceeding a predefined limit and such a change results in the device issuing an alarm signal indicating a leak has occurred in the tool. The device housing can be directly mounted to the tool, located remotely and connected with a coupling hose, or integrated with an accessory device connected to the tool. Preferably, the pressure differential is negative relative to ambient when the tool is a medical endoscope.

The invention relates to a working channel element for an endoscope. The working channel element has a tubular shape, which has an inner circumference and an outer circumference and through which an instrument can be pushed. The working channel element is adapted to be temporarily inserted into a working channel of an endoscope with its distal side ahead.
