A modular endoscope including a handle and sheath that can be coupled or uncoupled using a bayonet connection. For example, when the handle and sheath are mated or coupled, the sheath has deflecting capability and tip angulation can be accomplished through the handle. The tip of the sheath is capable of being deflected to allow the tip to be pointed in a specific direction. The tip of the sheath, which is distal from the location where the sheath is coupled to the handle, includes an illumination element, an image capture element.

A handle for a medical device comprises a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.

An illuminating wire medical device may include an elongate flexible housing and an illuminating fiber and a core wire extending through at least part of the housing, the core wire providing desired pushability and torquability. The illuminating device may further include a connector assembly cooperating with the illuminating fiber to accommodate changes in length and to absorb forces applied during use of the device.

A pressure monitoring device is provided for use with a tool such as a medical endoscope. The device includes a housing which is fluidically coupled with an internal volume of the endoscope. A pump is used to change the pressure inside the device housing and endoscope, thereby establishing a pressure differential from the ambient environment. During an endoscopy procedure, the pressure inside the device housing is monitored, and a change in pressure exceeding a predefined limit causes an alarm signal indicating a leak has occurred in the endoscope. The device housing may be directly mounted to the endoscope, located remotely and connected with a coupling tube, or integrated with an accessory device connected to the endoscope. The pump may be integrated internally to the device housing, or it may be a separate external pump which is connected to the housing. The pressure differential may be positive or negative relative to ambient.

An optical system for an endoscope includes an objective and a reversal system arranged after the objective. The reversal system includes at least one reversal stage for projecting the distal intermediate image as a proximal intermediate image into a proximal intermediate image plane. The reversal system imprints on the proximal intermediate image a first longitudinal chromatic aberration referred to a predetermined wavelength from the visible spectrum and a predetermined wavelength from the near infrared range. The objective imprints on the distal intermediate image a second longitudinal chromatic aberration referred to the predetermined wavelength from the visible spectrum and the predetermined wavelength from the near infrared range. The second longitudinal chromatic aberration has the opposite sign relative to the first longitudinal chromatic aberration, which reduces the longitudinal chromatic aberration caused by the reversal system in the proximal intermediate image.

An endoscope includes an insertion portion; an operation portion; a balloon water injection channel; a first opening portion; a balloon pipe sleeve provided with a first end portion and a second end portion; a branch channel connection unit; a rotation restriction portion; and a connecting tube on which the branch channel connection unit is assembled.

A medical device is provided comprising a first port; a second port in fluid communication with the first port; and a third port in selective fluid communication with both the first port and the second port; a sealing membrane disposed between the third port and both the first port and the second port, the sealing membrane is configured to move between a first position preventing fluid communication between the third port and both the first port and the second port and a second position allowing fluid communication between the third port and the first port, wherein movement of a fluid supplied to the medical device at the third port moves the sealing membrane from the first position to the second position.

A connector for connecting a medical tube set to a medical container, includes a collar connectable to a container, a cap having at least one opening for receiving a tube of a tube set, and an annular seal. The cap is located in the collar between an inner surface of the collar and the seat. The cap is rotatable relative to the collar. The collar includes a generally cylindrical side wall open at its upper and lower ends and an annular flange projects inwardly from the side wall at the upper end. The cap has a disc defining at least one opening and having an outer annular rim which locates between a lower surface of the annular flange on the collar and the seal.

A periodontal endoscope includes an imaging handle having an imaging end that supports a camera sensor and an introducer including an introducer blade such that the introducer blade is selectively rotatable about the camera sensor for engaging gingival tissue in the field of view for any rotational orientation of the introducer blade relative to the camera while illuminated by an optical fiber bundle. An automatic illuminance controller controls an illumination light source at least within each frame as the frame is scanned based on dynamic range of the camera sensor such that high intensity areas of the frame receive a reduced amount of illumination light by reducing the illumination drive signal as compared to low intensity areas of the frame which receive an increased amount of illumination light by increasing the illumination drive signal relative to the high intensity areas.

An adapter device for use in a reprocessing device for reprocessing surgical instruments. The adapter device including: at least one first fluid attachment, on an inlet side for connection to a coupling device of the reprocessing device; at least one second fluid attachment, on an outlet side for connection to the surgical instrument, the at least one second fluid attachment being adapted geometrically to an attachment of the surgical instrument; and an adapter identification feature that is detectable by the reprocessing device. Also provided is a reprocessing system having a reprocessing device for reprocessing surgical instruments and having the adapter device. The reprocessing device including: the coupling device for connecting to the adapter device; and a detection device which detects, with the adapter device connected to the reprocessing device, the adapter identification feature of the adapter device.
