摘要:
A delivery device for delivering a plurality of individual surgical fasteners. The delivery device includes a drive mechanism having distal and proximal ends. The drive mechanism has a moving member and a fixed opposing member, wherein the moving member is moveable proximally and distally with respect to the delivery device. The moving member has a sharpened distal end for piercing tissue. The device includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The device also has an actuator having at least two sequential positions. A first position for moving the moving member distally and piercing tissue, and a second position for moving the moving member proximally, thereby deploying the distal end of the fastener.

A delivery device for delivering a plurality of individual surgical fasteners is disclosed. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The device further includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The surgical fasteners are preferably made from a superelastic nickel titanium alloy. Additionally an actuator having at least three sequential positions is included. The first position of the actuator is for moving the drive mechanism distally. The second position is for moving the first member proximally to partially deploy the distal end of the fastener. The third position of the actuator is for moving the second member proximally, to fully deploy the distal end of the fastener.
摘要:
In accordance with the present invention there is provided a surgical fastening instrument. The instrument includes a handle and a shaft extending from the handle. The shaft contains a plurality of surgical fasteners therein. The instrument also has a mechanism for first distally deploying a penetrating member from the distal end of the shaft and thereafter feeding at least one of the surgical fasteners distally from the penetrating member. The instrument further includes a lockout mechanism for preventing the penetrating member from deploying from the shaft upon feeding all of the plurality of surgical fasteners from the shaft.
摘要:
An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfacing surface applying pressure in a predetermined range. A second pole is located one of the two interfacing surfaces. In a preferred embodiment, the second pole is located on the same interfacing surface as the first pole and an insulator electrically isolates the two poles. A preferred application of the invention is in a cutting instrument wherein a hemostatic line is formed along a cut line using RF energy.

Devices and methods are provided which may be used for suturing, including performing a totally transoral surgical procedure, such as a posterior gastropexy procedure. A suture lock and cut assembly is provided to lock and cut one or more sutures in one motion, which motion can be a non-curved, non rotational linear motion. The suture lock and cut assembly with one or more sutures threaded therethrough may be pushed through, for example, a patient's esophagus and into the stomach by the tip of an endoscope, or alternatively, sized to be fed through the working channel of the endoscope.

An improved electro surgical instrument is provided for cauterization and/or welding of tissue of varying impedances, thicknesses and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfacing surface. A second pole is located on one of the two interfacing surfaces. In a preferred embodiment, the second pole is located on the same interfacing surface as the first pole and an insulator electrically isolates the two poles.

A diagnostic device (10) for pathologies of tubular anatomical structures comprises a tubular elongated structure (12, 28) developing between a proximal end and a distal end and is suitable to be inserted in the tubular anatomical structure, means (22, 32) for locally dilating the walls of the tubular anatomical structure that are associated with the distal end of said elongated structure, said means for locally dilating being movable between a closed position for introducing the device and at least one open position for viewing and evaluating the pathology, and control means being associated with the proximal end of the elongated structure, said control means being operatively connected to said means for locally dilating, in order to move them between the closed position and the open position, and vice versa.
摘要:
An intubation device is provided for use with a guide apparatus having a track that is adapted to be associated with an endoscope such that bending of the track is substantially decoupled from bending of the endoscope. The intubation device includes an elongated, flexible tube defining a channel therethrough and having a plurality of spaced-apart apertures disposed on the distal portion, wherein the apertures are in fluid communication with the channel. The intubation device further includes a mating member attached to the tube and adapted to slidingly engage the track external of the endoscope.
摘要:
A method of resecting a portion of lung using an electrosurgical instrument is disclosed. The electrosurgical device clamps upon lung tissue and applies RF energy to create a cauterized zone within the clamped portion of the lung. At least one staple is placed within the cauterized tissue zone. The cauterized zone is cut adjacent to the at least one staple and the cut portion of the lung is removed.
