An access system is provided for establishing an access path to a surgical site within a patient. The access system comprises an access portal defining a working channel with a central axis, and an adaptor with a mating section mountable to the access portal. The adaptor is selectively rotatable about the central axis. The access portal includes a plurality of openings and the adaptor includes a plurality of projections, each of the projections and openings being arranged so that, in a first orientation, the openings and projections align to allow mounting of the adaptor to the access portal and, in a second orientation, the openings and projections do not align to prevent disassociation between the adaptor and the access portal. The adaptor also includes a holder for a viewing device, the viewing device being movable with the adaptor about the access portal and vertically translatable relative to the access portal.

A speculum comprising a lower member including a handle having a proximal end and a distal end, and a lower blade extending from the proximal end of the handle, an upper blade configured to be movable with respect to the lower member, and an illumination assembly including at least one light source, at least one power source housed in the handle and an ejection mechanism for removal of the at least one power source from the handle, wherein the at least one power source is housed in the handle at a position closer to the proximal end of the handle than to the distal end, and wherein the ejection mechanism is configured to remove the at least one power source via an opening formed in the distal end of the handle.

A surgical access device including a frame, first and second supports, and first and second retractor blades releasably coupled with the first and second supports, respectively. The frame has first and second arms. The first support is releasably coupled with the first and second arms. The second support is slidably mounted on the first and second arms. The second support is movable between a first position with the retractor blades in close cooperative position and a spaced apart position with respect to the first support. The first and second retractor blades each have a distal end portion configured and adapted to engage a vertebral body. In one method of use, the retractor is inserted through an incision in first orientation with the blades in close approximation and rotated approximately 90°, before spreading the retractor blades to retract tissue.

Methods for collapsing a tubular organ, such as the esophagus, involve inserting a device into the tubular organ, at least partially sealing off a section of the tubular organ, and drawing in the wall of the tubular organ by application of suction. The devices may be used to move the wall of the tubular organ away from an area undergoing treatment or therapy, such as to minimize damage to the tubular organ by application of radiofrequency energy or to limit temperature increase of the tubular organ.

In one embodiment, the present disclosure relates to a retractor apparatus that includes a retractor frame, five arms attached to the retractor frame and five rods each attached to one of the five arms. Each rod includes a convex surface facing a center of the retractor frame. At least two of the five rods are movable independently from one another. A first rod of the five rods includes a longitudinal axis and is translatable along the longitudinal axis. Further, the first rod is attached to a first arm of the five arms and is pivotable relative to the first arm. The axis of pivot is offset from the longitudinal axis through which the first rod translates.

Disclosed is a self-retaining retractor configured for insertion into an orifice. The self-retaining retractor may include a flexible structure made of, for example, one or more of an elastic polymer sheet and an elastic polymer mesh. Further, the self-retaining retractor may include a flexible or shape memory material, such as, for example, nitinol, polymer or elastomer, incorporated in the flexible structure. Further, the shape memory material may be configured to change a state of the self-retaining retractor between a collapsed state and an expanded state. Accordingly, in the collapsed state, the self-retaining retractor may be conveniently inserted into the orifice. Subsequently, the self-retaining retractor may be changed to the expanded state in which the self-retaining retractor applies outwardly radial force causing the orifice to increase in size.

Holding device for holding a manually operated medical device in place, comprising: a connector arranged to connect the holding device to a positioning apparatus; a clamp member arranged to clamp the medical device, wherein the clamp member is moveable between a locking position wherein the medical device is clamped and a moving position wherein the medical device is moveable with respect to the holding device; a joint assembly arranged to allow movement between the clamp member and the connector, wherein the joint assembly is moveable between a moving position wherein the clamp member is moveable with respect to the connector and a locking position wherein movement between the clamp member and the connector is prevented, and; an actuator for moving both the joint assembly and the clamp member between the moving positions and the locking positions.
