摘要： An endoscopic device, includes a clip assembly and a driving assembly. The clip assembly includes a first jaw, a second jaw, a pivot, a housing having an internal channel, and a release portion connecting to the first and second jaws. At least a portion of the first and second jaws is disposed within the internal channel, the first and second jaws selectively move along with the internal channel. The driving assembly includes an outer sheath, an inner tube, movably disposed within the outer sheath, and a driver, movably disposed within the inner tube, and removably received within the release portion. The driver is unbrokenly released from the release portion by a predetermined pull force. The housing and the outer sheath form a releasable handshake engagement. The inner tube extending into the housing prevents the handshake engagement from disengaging.

摘要： An endoscopic resection assembly includes an adaptor configured to adapt to an endoscopic device. A pusher is disposed on the adaptor by inserting the adaptor into the central opening defined by the pusher. A cutting device includes a snare loop and a snare drive cable, and is removably coupled to the pusher. The cutting device is configured to resect a tissue when the snare loop is contracted by activation of the snare driver. A clip for engaging onto the tissue can be loaded onto the adaptor at a position distal to the pusher.

摘要： An endoscopic device for retrieving an object from within a human body is disclosed. The device includes a support assembly, a transmitting assembly, a wire, and a net element. The support assembly has a base and a tubular member. The transmitting assembly includes a handle and a motion transmitting link fixed to the handle and extending through at least a portion of the tubular member. The wire defines a loop portion and two leg portions. A proximal end of each leg portion is secured to the link by a first connection and the two leg portions are secured to each other by at least a second connection distal from the first connection. The net element has a distally protruding portion secured to the loop portion and a proximally protruding portion secured relative to the leg portions.

摘要： An improved system for attaching devices to the distal end of endoscopic instruments is described. An attachment adapter comprises a distal stop, such as a complete or partial loop or cylinder, which limits the penetration of an endoscope into the adapter. The adapter has at least one flange protruding proximally along the endoscope. The adapter is secured on the endoscope by a securing means, which compresses the flange or flanges sufficiently to provide a friction fit. The flexibility of the inventive adapter system allows the adapter to work reliably with endoscopes that are used, damaged or repaired. The adapter may further provide a slit or window allowing viewing of the vessel wall by a lens on an endoscope, thereby improving the operator's ability to understand the location of the endoscope during operation. The adapter may carry any of a variety of devices, including devices for closing a surgical incision, or treating or manipulating tissue. Improvements are described in a number of areas to allow more flexible pairing of particular endoscopes or endoscopic instruments with devices to be carried on their exteriors, while maintaining a tightly locked position of the external device on the carrier.

摘要： A rotatable jaw device for use with an endoscope and method of using a rotatable jaw device. The device includes a fork, and two jaws pivotally mounted to the fork. The jaws are movable between a predetermined closed position and a predetermined open position. At least one jaw has at least one protrusion on a surface of the jaw. The at least one protrusion prohibits movement of the two jaws in the opening direction beyond the predetermined open position. One jaw may have an elongated center void defined by twin jaw extensions, and the other jaw may rotate within the elongated center void when the two jaws move toward the predetermined closed position.

摘要： An endoscopic surgical device for retrieving severed tissue or foreign bodies from within a subject is disclosed. The device comprises a support unit and a tissue retrieving net. system. The net system is carried by the support unit and may be inserted into the subject through an orifice or small incision and operated to retrieve tissue that has been severed by a conventional method. The net system comprises a net, a net actuator, a: net deployment and retrieval assembly for transmitting motion between the net and its actuator. The net system further comprises at least one net connector disposed such that only one connector is within an articulation zone, defined by locations of severe bending of the device during operation.
