An anoscope comprises a graspable portion, arranged for being grasped by an operator, and a body, arranged for being inserted into the terminal tract of the rectum of a patient. A cavity and at least one operating window are made in the body of the anoscope. The anoscope further comprises a housing and a seat, which are comprised in the cavity of the body. The housing is arranged for containing at least one surgical instrument suitable for treating hemorrhoids and the seat is arranged for containing at least one lighting device. A method for treating a hemorrhoid in a patient comprises the following steps: a) Inserting an anoscope into the terminal tract of the rectum of the patient through the anal opening; b) Positioning the body of the anoscope in such a way that an operating window or opening of the anoscope is near a zone of rectal mucosa to be treated, positioned near the hemorrhoids; c) Positioning a surgical instrument suitable for treating hemorrhoids inside the body of the anoscope so as to reach the operating window or opening and, through the operating window or opening, reaching the zone of rectal mucosa to be treated; d) Producing a localized heat in the submucosa of the zone of rectal mucosa to be treated through the surgical instrument, such localized heat being a heat that is limited to the zone of rectal mucosa to be treated; e) Inducing a volume reduction of the hemorrhoid as a result of the localized heat produced.

A device for use in the treatment of hemorrhoids. The device includes an elongated tube-shaped element that includes a forward end and an aft end. The aft end provides access to the interior of the tube-shaped element. The tube-shaped element extends along a longitudinal axis L and includes at least one opening formed between the forward and aft end. The device includes an anal mucosa support device removably arranged within the tube shape element. The support device includes at least two cavities to receive anal mucosa. At least one needle guide structure is formed in the elongated tube-shaped element and the anal mucosa support device such that at least one needle is capable of being guided during movement within the tube-shaped element across the at least two cavities in the anal mucosa support device to a position where the needle extends across the opening in the tube-shaped element.

Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

A device for surgical interventions comprises (i) an inner end (1) guidable/steerable to an operation field, (ii) an outer end (3) operated by user and (iii) a middle part (2) which connects both ends (1, 3) together. Force transmission units extend between the outer end (3) and the inner end (1). The force transmission units, the outer and the inner ends and the middle part (2) transfer movements of the outer end (3) to the inner end (1) in an identical measure, as if the inner end (1) was a straight continuation of the outer end (3).

Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

Embodiments relate to robotic arm assemblies. Embodiments include shoulder segment and upper arm segment having motor drive portion. Embodiments include shoulder coupling joint assembly connecting upper arm segment to shoulder segment. Shoulder coupling joint assembly includes distal shoulder joint subassembly connected to upper arm segment. Distal shoulder joint subassembly includes distal shoulder joint forming first axis. Distal shoulder joint subassembly includes shoulder planetary gear assembly having shoulder sun gear configured to rotate relative to first axis when motor drive portion is driven to rotate. Shoulder planetary gear assembly includes shoulder planetary gear carrier. When shoulder sun gear rotates, shoulder planetary gear carrier drives upper arm segment to rotate relative to first axis. Shoulder coupling joint assembly includes proximal shoulder joint subassembly connecting shoulder segment to distal shoulder joint subassembly. Proximal shoulder joint subassembly includes proximal shoulder joint forming second axis, which rotates distal shoulder joint subassembly relative to second axis.

A rectal band ligation device and a method of operating the band ligation device. In one embodiment, the band ligation device includes: (1) a handle having a trigger associated therewith, (2) an extension tube extending from the handle and terminating in a head, (3) at least two openings in the head, (4) hollow pistons located in the openings and configured to move relative thereto between an extended position in which ends of the pistons are exposed through the openings and a retracted position, gaps between corresponding openings and hollow pistons being less than cross-sectional widths of elastic members stretched around the ends and (5) an actuating rod coupling the trigger and the pistons and configured to cause the pistons to move from the extended position to the retracted position.

A system for performing a medical procedure at a target location of a patient, including: an articulating probe including at least a distal portion; a feeder configured to advance, retract, and steer the articulating probe; a first introducer attached to the feeder and configured to slidingly receive the articulating probe; and a second introducer for providing access to an internal location of the patient. The first introducer operably attaches to the second introducer, such that the articulating probe can be advanced through the second introducer to the target location. The system further includes at least one sealing element configured to maintain insufflation pressure at the target location.

An overtube device includes: a tube body having a bending part and a main body part; a wire having a distal end part fixed to the bending part and a proximal end part positioned on the proximal end side and extending along a longitudinal axis; an operation part capable of pulling the wire to the proximal end side; and an overtube base configured to fix the tube body in a longitudinal axis direction so as not to advance and retract, and configured so that the operation part is provided in a state where the wire is pulled toward the proximal end side of the wire until a curved shape of the bending part is held. In a state where the operation part is mounted on the overtube base, the overtube base holds the wire in a state where the wire is pulled toward the proximal end side of the wire.

A surgical instrument includes a hollow member having a sidewall provided with a window and a closure member movably connected to the hollow member for alternately covering and uncovering the window. The hollow member has a first clamping surface along an edge of the window, while the closure member has a second clamping surface opposing the first clamping surface and disposable substantially adjacent thereto in a clamping or closure configuration of the instrument. The instrument additionally comprises a tissue occlusion component mounted to at least one of the hollow member and the closure member for acting on tissues gripped between the first clamping surface and the second clamping surface, to couple the tissues to each other.
