A control system for a colonoscope having a shaft deflectable via two rotatable knobs is provided. The system includes a first drive unit mounted externally to a housing of the colonoscope. The first drive unit includes a first drive mechanism for engaging the two rotatable knobs or gears replacing the two rotatable knobs. The system further includes a second drive unit attachable to the shaft of the endoscope. The second drive unit is capable of linearly translating the shaft forward and backward. A user interface engageable by a palm of a hand controls the first drive mechanism.

A bending operation mechanism for an endoscope, which is a pulley unit, includes: an up-down bending pulley which is a rotation body; an angle wire which is a bending-portion pulling member having a distal end side connected to a bending portion and a proximal end side that is pulled by the up-down bending pulley; and a spiral spring which is a slack absorption member having a first end connected to the an proximal end of the angle wire and a second end side connected to the up-down bending pulley and configured to pull the angle wire in the direction toward the up-down bending pulley.

According to one aspect, a dilation device may include a body, at least one loop actuator attached to the body, and a sheath attached to the body at a proximal end and attached to the loop actuator at a distal end.

An endoscope including a handle housing having apertures for legs of an operating part, an electrical switch positioned in the handle housing and having a carrier board having apertures for the legs. The operating part includes a finger pad having a finger surface, a ring connected to and extending from the finger pad, the ring having a plunger aperture, legs connected to and extending from the ring, the legs each having a spacer section and an electrical switch retention protrusion. The legs traverse the apertures of the handle housing and the carrier board to secure the electrical switch to the housing handle. The finger pad comprises elastically deformable material configured to extend toward and cause actuation of the electrical switch, when pressure is applied and to return to a rest position when pressure is released.

The invention relates to a video endoscope (10) with an endoscope (20) comprising endoscope optics (22) and a camera head (30) comprising camera electronics (35) and a display and control unit (36), wherein a vacuum pump (40) is arranged in the video endoscope (10) for aspiration of air from the environment of the video endoscope (10).

Further, the invention relates to an envelope (70) suitable to receive a video endoscope (10) comprising a hollow tube (71) having a distal end (71a) and a proximal end (71b), wherein the distal end (71a) is closed by means of an optically transparent window (72), wherein a flexible pouch (73) having an inlet opening (74) is arranged at the proximal end (71b), wherein the inlet opening (74) of the pouch (73) is implemented to be closable by means of a closure (75).

Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

Systems and methods for compensating for observer movement during robotic surgery. An exemplary system includes an image capture device configured to capture images of a surgical site, a stereoscopic display device, a sensor configured to detect positions of an observer, and a computing device including a processor and a memory storing instructions. The instructions, when executed by the processor, cause the computing device to receive the images of the surgical site from the image capture device, receive data from the sensor indicating a position of the observer, process the received images of the surgical site based on the movement of the observer, and cause the stereoscopic display device to display the processed images of the surgical site.

The invention provides a flow device for creating a flow of bubbles of a contrast medium. The device comprises a pump which is configured to provide a flow of the medium and an elongated insertion tube attached to the pump at a proximal end. The elongated insertion tube forms a flow path between the proximal end and an outlet at a distal end.

An endoscope including steering and braking mechanisms. The braking mechanism includes a manually operable braking control element, a friction element which is axially translatable along a control axis to engage or disengage with the steering mechanism, and a cam pairing transmitting force between the braking control element and the friction element and transforming the braking input into an axial translation of the friction element. The cam pairing has a cam surface and a cam axially contacting the cam surface. The cam surface forms a first ramp section for translating the friction element from a first braking position to an intermediate braking position, a second ramp section for translating it from the intermediate braking position to a second braking position, and an intermediate section forming a tactile structure arranged between the first ramp section and the second ramp section and defining the intermediate braking position.

A medical device including a handle and a flexible member controlled by the handle, the handle including one or more knobs, each of the one or more knobs having a plurality of protrusions spaced circumferentially from one another, wherein the medical device comprises one or more grip-enhancing features configured to be removably coupled to the one or more knobs.
