The invention concerns a handle for a video endoscope including a housing and an interface portion rotatably supported relative to the housing where the interface portion includes a first connector element at its distal end section that is connectable to a second connector element of an associated elongate shaft of the video endoscope. Thereby a detachable, rotatable electrical and/or mechanical connection between the handle and the associated shaft is achieved. The coupling includes an electrical connection assembly arranged at an exterior of the interface portion forming an electrical connection to a stationary electric component of the handle. The handle includes a mechanical rotation stop for a rotation of the interface portion relative to the housing such that a rotation range is limited and damage to the electrical connection assembly is prevented.

The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.

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.

An accessory device for assisting insertion of a catheter is disclosed. The accessory device comprises a handle comprising an attachment means for releasably coupling a catheter to the handle, and a camera for capturing one or more images, and a monitor in communication with the camera is disclosed. The monitor comprises a display configured to display the one or more images. The accessory device provides for visualizing the meatal area on a monitor by means of a camera moving in unison with the catheter, such that the user is assisted in identifying the meatus and inserting the catheter.

An enhanced flexible robotic endoscopy apparatus includes a main body and flexible elongate shaft. The main body comprises a proximal end, a distal end and a housing that extends to the proximal end and the housing comprises a plurality of surfaces and a plurality of insertion inlets which reside on at least one of the surface of the housing at the proximal end of the main body, through which a plurality of channels for endoscopy are accessible. Each of the insertion inlets has insertion axis corresponding thereto, along which flexible elongate assemblies are insertable, with the insertion axes of the insertion inlets being parallel to the central axis of the flexible elongate shaft at the proximal end of the flexible elongate shaft.

An endoscope (1) including a handle (2), an insertion cord (3), and a steering mechanism, the insertion cord (3) including an insertion tube (4), a bending section (5) and a distal tip unit (6), the steering mechanism including a manually operable steering input element (7) to receive a rotational input by a user and being connected to a control shaft, which is rotatably supported at the endoscope handle (2) and a steering switch mechanism (13) configured to switch a coupling state of the steering input element (7) at least between a first mode of operation, in which the steering mechanism bends the bending section (5) in a first bending plane, and a second mode of operation, in which the steering mechanism bends the bending section (5) in a second bending plane.

A tissue resecting device includes an elongated shaft having a central axis, a distal end, and a proximal end. A ceramic or other housing is mounted at the distal end of the shaft and has a tissue-receiving window. A movable electrode is configured to be rotationally oscillated or otherwise moved across the window. In one instance, the rotatable moveable electrode may have a dogleg configuration with a free end constrained within an arcuate slot formed near the window. In another instance, the movable electrode may have a U-shaped configuration with a distal end coupled to a pivot in the housing which is aligned with a rotational drive member.

An endoscope for removing tissue at a surgical site includes an elongated tubular body insertable within a mammalian cavity of a patient. An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component of the surgical cutting assembly responsive to actuation of the torque generation component.

An endoscope including a coupling member (19) for coupling an insertion tube of the endoscope to an endoscope handle. The coupling member includes a proximal end (21) and a distal end (22) and a passage (20) between an opening in said proximal end (21) and an opening at said distal end (22). The coupling member (19) includes surface features (24) distributed along the circumference and adapted to engage rotation preventing features within an endoscope handle. The coupling member is used in a method for assembling the endoscope.

A system for performing minimally invasive procedures in a body lumen of a patient including a flexible catheter having a first lumen configured and dimensioned to receive an endoscope therethrough and a second lumen configured and dimensioned to receive a first flexible tube therethrough. The first flexible tube is movable through the second lumen and has a distal portion including a first curve extending in a first direction with respect to the longitudinal axis and a second curve extending in a second different direction with respect to the longitudinal axis. A retractor system is positioned at a distal portion of the catheter and is movable from a non-expanded insertion position to an expanded position forming an expanded cage to form a larger working space. The distal portion of the first flexible tube is movable within the expanded cage.
