A control system for a coupling an input device and an input module of an imaging system for a medical procedure includes a compatibility module and a magnetic force module. The compatibility module generates a compatibility signal indicating the input device is compatible with the input module or indicating that the input device is incompatible with the input module based on electronic information stored on the input device. The magnetic force module that generates a magnetic force between a connector of the input device and a receptacle of the input module based on the compatibility signal.

A plug of a connector for connecting an optical waveguide provided in a medical instrument includes: a coupling portion configured to be inserted into a receptacle of the connector; a connecting surface formed at an end in a first direction in which the coupling portion is inserted into the receptacle; an opening portion provided on the connecting surface, the opening portion having a recessed shape; and a holding portion configured to hold the optical waveguide such that an end face of the optical waveguide is directed in the first direction. The holding portion and the optical waveguide are disposed on a side of a second direction with respect to the connecting surface, the second direction being opposite to the first direction.

An endoscope apparatus includes a removable optical adaptor and a main body optical system. The optical adaptor includes an aperture and includes a first group optical system having a negative combined focal length as a whole and a second group optical system having a positive combined focal length as a whole in order from an object side. The main body optical system includes an imaging lens configured to form an image of a light flux on an image pickup device, the light flux being transmitted through the adaptor from the object. The first group optical system includes a lens having an Abbe number of 35 or higher, and the second group optical system includes a lens having an Abbe number of 45 or lower.

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.

Various embodiments are generally directed to fluid container adapters that couple with a fluid container, so to enable access to the contents of the fluid container, such as from an endoscopic system via a tubing set. Several embodiments are particularly directed to a fluid container adapter that can couple with an opening in a variety of fluid containers to place one or more tubes in fluid communication with an interior of any particular one of the variety of fluid containers.

Various embodiments are generally directed to fluid container enclosure systems that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. The enclosure systems are configured to fit a wide range of fluid container necks, ports, or other openings, including various opening dimensions, thread finishes, and/or thread dimensions. In one embodiments, an enclosure system may include a cap having multiple carriages arranged therein. For example, a primary carriage may be arranged within the cap to engage with larger-dimensioned bottles. A secondary carriage may be arranged to float within the primary carriage to engage smaller-dimensioned bottles that bypass the primary carriage. Other embodiments are described.

Various embodiments are generally directed to fluid container enclosure systems that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. The enclosure systems are configured to fit a wide range of fluid container necks, ports, or other openings, including various opening dimensions and thread finishes. In one embodiment, an enclosure system may include a plug having a sleeve extending therefrom. The plug may be deformed manually or via a plunger system to reduce the outer dimension thereof to fit the plug in the neck of a fluid container. Once the plug is arranged within the neck, the sleeve may be folded down over an outer surface of the neck to form or reinforce a seal between the enclosure system and the neck of the fluid container. Other embodiments are described.
