Принадлежит: Alfred E.Mann Institute for Biomedical Engineering at the University of Southern California

This application presents a bifurcated, optimally-angled surgical forceps. In one example, this surgical forceps may enable a more natural maneuver for initial clamping of the vas deferens through the scrotal skin. This may be more comfortable for users and easier to maintain, and may provide greater tactile surface contact between the thumb and vas deferens. This device also may provide the surgeon with an entire segment of vas deferens upon which the vasectomy may be performed, thus reducing the need for frequent repositioning of instruments. The device may also be applied to other surgical procedures that may benefit from the features of the device and where a section of a tubular anatomical structure may need clamping at two points along its length. Examples include blood and lymphatic vessels, ducts of the digestive system, and large nerves or nerve bundles. 1.

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.

Автор: Andrzej Janusz Decewicz, Wieslaw Mieczyslaw Brodaczewski

Принадлежит: Grena Usa LLC

A retainer for a ligating clip cartridge includes a peripheral skirt nested within the cartridge. The retainer includes a planar peripheral top margin surface extending from the skirt. A plurality of spaced rectilinear upwardly arched boundary leaves project from opposite sides of the top margin surface. The distal ends of the boundary leaves include a pair of spaced, downwardly inclined integral distensions. When positioned within a cartridge loaded with clips, the distensions are registered with and spaced above bosses which extend transversely from each clip leg. Should the clips tend to prolapse within the cartridge; the bosses engage a keeper notch formed at the juncture between the upwardly arched boundary leaves and the downwardly inclined distensions to maintain the clips in position suitable for dispensing.
