A medical device includes an endoscope head which is designed to be detachably connected to endoscope tubes. The endoscope head has a longitudinal channel between a proximal end and a distal end of the endoscope head for receiving an endoscope tube. At least one measuring channel is arranged in the endoscope head. The measuring channel has at least one inner connection opening, which is connected to the longitudinal channel, and at least one outer connection opening, which is arranged on the outside of the endoscope head. The outer connection opening can be connected to at least one measuring channel in a measurement adapter which can be detachably coupled to the endoscope head.

An endoscopic device is provided. The endoscopic device may comprise a distal end and a proximal end. The proximal end may be opposite the distal end. The endoscopic device may further comprise a handle at the proximal end and a tube extending from the handle towards the distal end of the endoscopic device. The endoscopic device may further comprise an accessory channel. The accessory channel may extend through the tube. The endoscopic device may further comprise a slide, the accessory channel extending through the slide, and a curved track disposed adjacent to the proximal end of the endoscopic device. The slide is movable within the curved track to cause movement of the accessory channel within the tube.

A method can include inserting a first device into a body lumen having a bend, sliding a first sheath having a first sheath diameter over first device, sliding a second sheath having a second sheath diameter larger than the first sheath diameter over the first device, and navigating the first device through and beyond the bend. The method can also include at least partially straightening the first device to at least partially straighten the bend, removing the first device and the first sheath from the body lumen, leaving the second sheath in place within the at least partially straightened bend, and introducing a second device into the second sheath to navigate the second device through the at least partially straightened bend to an opening of the second sheath.

A ventilation pipe sleeve system comprises a ventilation pipe sleeve, a first filter, and a cap attached to the ventilation pipe sleeve. The ventilation pipe sleeve includes a tubular body including an outer surface and an inner surface. The inner surface of the tubular body defines a conduit extending from a first end to a second end of the ventilation pipe sleeve. The first filter is liquid impermeable and is gas permeable, the first filter is fixed to the tubular body to form a watertight structure at a first end region of the tubular body. The cap covers the first filter and at least a portion of the outer surface of the tubular body.

An endoscope assembly includes a shaft assembly, an endoscopic camera assembly, and an anatomy elevation assembly. The shaft assembly includes a flexible outer shaft defining a lumen, a first electrical communication line, and a first fluid communication line. The endoscopic camera assembly is in communication with the first electrical communication line. The anatomy elevation assembly includes an inflatable member coupled to the flexible outer shaft. The inflatable member includes an interior surface. The first fluid communication line is in fluid communication with the inflatable member. The inflatable member is configured to transition between a deflated configuration and an inflated configuration. The interior surface is configured to define a viewing path distal to the endoscopic camera assembly while the inflatable member is in the inflated configuration.

Some implementations of the disclosure relate to an adapter, comprising: a channel running through the length of the adapter from a first opening to a second opening of the adapter, wherein a shaft of an endoscope is configured to be threaded through the channel; a first coupler configured to removably secure the adapter to a second coupler of the endoscope, the first coupler comprising the second opening; and a rigid attachment segment comprising a surface configured to removably couple the adapter to an instrument or second adapter. The surface of the rigid attachment segment may include multiple grooves and sections alternating along the longitudinal length of the rigid attachment segment, each section protruding relative to the grooves and comprising a recessed indentation or protrusion; and the multiple sections and grooves configured such that the instrument or second adapter can be coupled to the adapter in multiple lengthwise positions.

Endoscopes and methods of their use, where the endoscopes provide a low profile or cross-section which facilitates introduction through small body passages, such as patient's cervix, and into body cavities, such a patient's uterus.

Some implementations of the disclosure relate to an endoscope, comprising: a shaft comprising: a distal end; and a proximal end comprising a rigid attachment segment configured to be removably coupled to an adapter or instrument, a surface of the rigid attachment segment comprising: a groove and a section adjacent the groove, the section protruding relative to the groove and comprising a recessed indentation or protrusion; and a housing coupled to the shaft. The surface of the rigid attachment segment may include multiple grooves and multiple sections alternating along the longitudinal length of the rigid attachment segment; each of the sections protrudes relative to the grooves and comprises a recessed indentation or protrusion; and the multiple sections and the multiple grooves are configured such that the instrument or the adapter can be coupled to the endoscope in a plurality of lengthwise positions.

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.

An endoscope aid attachably and detachably attached to a treatment tool insertion channel of an endoscope includes a flexible tubular-member longer than a total length of the treatment tool insertion channel. The tubular-member has a treatment tool insertion pipe line and a suction pipe line. A distal end part of the tubular-member has a sliding contact part that has an outer periphery coming in sliding contact with an inner peripheral surface of an outlet portion of the treatment tool insertion channel maintained in the shape of a straight pipe irrespective of bending of a bending part of the endoscope and is disposed in the outlet portion, and an extending part that extends from the sliding contact part to a distal end side and is disposed to protrude from an outlet of the treatment tool insertion channel. A distal-end-side opening of the suction pipe line is provided in the extending part.
