An endoscope operation portion includes: an operation portion body provided being connected to a grasping portion; a joystick-type bending operation lever provided on a back side of the operation portion body, including a lever shaft body, and configured to perform a bending operation of a bending portion; and a suction button provided on a front side of the operation portion body so that an angle formed by an operation axis in a pressing-down operation direction relative to a central axis of the lever shaft body is an obtuse angle, and an intersection point between the central axis and the operation axis is positioned inside the operation portion body.

An illuminated translucent endoscopic probe system includes a handle and rigid elongate body for passage into and through hard and/or bony tissue and includes an integrated camera and light source positioned distally from the handle and adjacent a distal tip that includes a transparent driving head. The system provides real time visualization at the distal end as it passes into and through tissue.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

Provided is an overtube capable of suppressing closing of a ventilation hole provided in an overtube body during endoscopy. An overtube (10) of the present invention includes an overtube body (70) and a balloon (78) that is disposed between a first position (P1) in a direction of a central axis (A) of the overtube body (70) and a second position (P2) positioned on a proximal end (74) side of the overtube body (70) from the first position (P1). The overtube body (70) is provided with a ventilation hole (94) that allows an outer circumferential surface (70A) and an endoscope insertion passage (71) to communicate with each other. The ventilation hole (94) is provided in a ventilation hole-formed region (70D) provided on the proximal end (74) side from the second position (P2). The ventilation hole-formed region (70D) is in a region within a range of 5 mm or more and 100 mm or less from the second position (P2) toward the proximal end (74) side of the overtube body (70).

An endoscope having a multiple diameter working section is disclosed. The endoscope includes a housing, a working section, and a rod-lens optical system. The housing is at a proximal end of the endoscope. The working section is integral with and extends from the housing. The working section includes at least a first section and a second section. The first section is contiguous to the housing, and the second section is at a distal end of the endoscope. The rod-lens optical system is positioned at least partially in the first section of the working section and at least partially in the second section of the working section. The endoscope is defined such that the outer diameter of the first section is larger than the outer diameter of the second section.

A surgical console includes a drive assembly, vacuum interface, fluid transfer device, user interface, and control circuit. The drive assembly is configured to be coupled to an endoscopic tool and to be rotated by a motor. The vacuum interface is configured to apply a vacuum to the endoscopic tool. The fluid transfer device is configured to flow fluid through the endoscopic tool. The user interface is configured to receive a user input indicating at least one of instructions to rotate the endoscopic tool while applying the vacuum, or to flow fluid through the endoscopic tool. The control circuit controls at least one of the drive assembly, the vacuum interface, or the fluid transfer device based on the instructions, and is configured to cause the drive assembly to rotate the endoscopic tool while the vacuum interface applies the vacuum responsive to the user input indicating instructions to rotate the endoscopic tool.

Improved laryngoscopes are disclosed herein which are capable of aiding operators toward successful intubation outcomes in clinical situations which would be difficult using previously existing tools.

An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.

An endoscope particularly suited for endocranial procedures and a method of using the endoscope. In some examples the endoscope is rigid except for a bend/tilt portion near a distal end of a rigid tube that is inserted in a patient's cranium, which distal end is controlled in a degree and direction of tilt with a finger operated controller at the endoscope's handle. Some examples use telescoping tubes that allow customizing the endoscope size for specific procedures. A distal portion of the endoscope can be disposable, supplied in a sterile package for a single procedure, thus taking into account contamination dangers that are particularly high for intracranial and certain other interventions and the fact that it can be difficult or impossible to effectively autoclave heat-sensitive components of certain endoscopes or effectively sterilize them using other techniques.

Endoscope assemblies, biopsy caps, and methods for making and using the same. An example endoscope assembly may include an endoscope having a channel formed therein and a port that provides access to the channel. A cap may be coupled to the port. The cap may include a base having a securing member for securing the cap to the port, an outer shell and a brush section disposed within the interior volume adjacent the disk shutter section, the brush section including a plurality of brushes arranged in a helical fashion.
