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 assembly for redirecting light emitted by an end-emitting optical fiber into an inner lumen of a body is provided. According to one implementation, the body includes one or more surfaces disposed on or in the body onto which the light is configured to impinge when the end emitting optical fiber is activated, the one or more surfaces being configured to alter the trajectory of the light so that the light is directed to impinge on a light reflector of a cap removably attached to the body, the light reflector of the cap being configured to redirect the light distally into the inner lumen of the body.

A surgical access assembly may include an outer sheath defined by an open distal end and an open proximal end and including a hollow body portion therebetween, and a flexible tool delivery device having a hub and a guide tube, the hub configured to selectively secure to a rim at the proximal end of the outer sheath, and the guide tube configured to extend at least partially into the outer sheath and provide a flexible tool proximate to a tissue.

An endoscope (1) including a handle (2) arranged at a proximal end and an insertion tube (3) extending from said handle (2) towards a distal end, a bending section (7) arranged at the distal end and controllable by and operator via control input means (8) arranged at the handle (2); and at least one insertion tube part with at least one lumen, wherein the bending section (7) is displaceable in said lumen so as to be movable relative to the insertion tube (3) from a retracted position within said lumen to an extended position at least partially outside said lumen.

An endoscope includes an operation portion provided on a proximal end side of an insertion portion and a treatment instrument insertion port to which a treatment instrument is inserted, and includes a forceps pipe sleeve provided in the operation portion with an axis direction of a central axis passing through the treatment instrument insertion port being different from an axis direction of the insertion portion, a flexible channel tube extending in a bent state from a proximal end of the insertion portion toward a forceps pipe sleeve and connected to the forceps pipe sleeve by insertion inside the operation portion, and a guide wall provided inside the operation portion and being contactable with an outer side portion of a bend of the channel tube by abutting on the channel tube.

A medical instrument for enhancing diagnosis and treatment comprising a handle, an ablation probe extending from the handle, a catheter extending from the handle. The catheter defines a lumen and the ablation probe is located within the lumen of the catheter. A port in fluid communication with the lumen of the catheter is configured for connection to a vacuum or fluid source, and application of a vacuum or an injection of fluid creates a consistent zone of permittivity around the ablation probe.

The endoscope includes an insertion portion, a hand-operating unit, a first treatment-instrument conduit, and a second treatment-instrument conduit. One end of the insertion portion is coupled to the hand-operating unit. The first treatment-instrument conduit passes through insides of the insertion portion and the hand-operating unit. A treatment instrument is inserted into the first treatment-instrument conduit from an upper end of the hand-operating unit. The second treatment-instrument conduit passes through insides of the insertion portion and the hand-operating unit and includes a branching portion that branches off into a first branching path and a second branching path at the hand-operating unit, a treatment instrument is inserted into the second treatment-instrument conduit from the first branching path. The first treatment-instrument conduit includes a first part having a first hardness at least at a grip portion in the hand-operating unit and a second part having a second hardness smaller than the first hardness.
