摘要： A medical device includes a control handle, an end effector, and a passive articulating joint connecting the end effector to the handle. The handle has a stapling actuator, an articulation joint actuator different from the stapling actuator, and a body through which the stapling and articulation joint actuators traverse. The end effector has an anvil, a stapler cartridge with staples, and an anvil-cartridge control device connected thereto and to the stapling actuator and staples when the stapling actuator is actuated. The stapling actuator passes through the articulating joint and flexes correspondingly to articulation of the articulating joint. The articulation joint actuator, when unactuated, holds the articulation joint and, thereby, the end effector, in a substantially fixed articulation position, and, when actuated, releases the articulation joint into its freely articulating state to permit free articulation of the end effector dependent upon external forces acting upon the end effector.

摘要： A compression-self-adjusting staple includes a substantially U-shaped staple body and a compression device. The staple body has a bridge and two legs extending from the bridge at an angle thereto. Each of the legs has a base end integral with the bridge and a deformable distal end defining a stapling point shaped to pierce material to be stapled. The compression device is at least partly disposed between the legs and has a bias portion with a compression surface movably disposed between the legs and a compression resistor connected to the bridge and to the compression surface and formed to resist movement of the compression surface towards the bridge with a force.

摘要： A surgical retractor includes a “swivel” having a string extending from one end and a string extending from the midpoint between the two ends. The swivel is delivered by pushing it out of a tube which is inserted through a small incision between the ribs of the patient. After the swivel is deployed, the tube is removed and the string which is attached to the center of the swivel is pulled to lift the pericardium. When the procedure is complete, the swivel is removed from the patient by pulling the string attached to the end of the swivel. According to one embodiment, the swivel is a cylinder with a blunt conical end. According to another embodiment, the swivel has a sharp end which is covered by a spring loaded collar.

摘要： A clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is adjacent to the jaw assembly and a clip pusher is adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a portion. The threaded portion engages a threaded member coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

摘要： The filter device captures embolic material in a blood vessel and is placed in the blood vessel via a guide wire. The guide wire has a proximal end, a distal end and a stop near its distal end. The filter device includes an expandable frame of frame struts having a closed, radially compact form and an open, radially expanded form. The frame, in the radially expanded form, has frame struts forming a pair of facing frustoconical frame structures. Filter material is attached to one of the pair of frustoconical frame structures. In one embodiment, the filter material is a perforated membrane. The guide wire extends through the expandable frame and the expandable frame is freely movable over the guide wire (likewise, the guide wire is freely movable within the frame), both rotatably and longitudinally, except distally beyond the stop near the distal end of the guide wire. This mobility of the guide wire with respect to the expandable frame enables to guide wire to be guided by the operator through the blood vessel.

摘要： An end effector assembly for an endoscopic instrument includes first and second end effectors, a screw and optionally a washer. The end effectors have arms which are biased away from each other. The screw has a threaded portion dimensioned to engage the distal end of the endoscopic instrument and a head portion with a pair of arm receiving grooves. In a presently preferred embodiment, the washer extends over arms of the end effectors which pass through grooves in the head of the screw. In this manner, the arms of the end effectors are captured between the screw and the washer. The grooves are preferably provided with upstanding pins which engage mounting holes in the arms of the end effectors.

摘要： An endoscopic multiple sample bioptome includes a hollow outer member and an axially displaceable inner member extending therethrough. The proximal ends of the outer and inner members are coupled to an actuator for axially displacing one relative to the other. The distal end of the outer member is coupled to one of a cylinder having a sharp distal edge and a jaw assembly, while the distal end of the inner member is coupled to the other. The jaw assembly includes a pair of opposed, preferably toothed jaw cups each of which is coupled by a resilient arm to a base member. The arms are bent to lie in planes which intersect the axis of the base member and to locate the jaws apart from each other. The base member is mounted inside the cylinder and axial movement of the jaw assembly and cylinder relative to each other draws the arms into the cylinder and brings the jaw cups together in a biting action. The biting action is enhanced according to the invention by arranging the cutting edge of each jaw to lie in a plane which intersects the plane in which the distal portion of the jaw arm lies. The biting action is further enhanced by providing a closing cam on the outer surface of the jaws which is engaged by the cylinder when the jaws are closed. The arrangement of the cutting edges also presents a smooth surface to the interior of an endoscope and the closing cams prevent the sleeve from sliding completely over and off of the jaws.

摘要： A non-metallic end effector for use in an endoscopic surgical tool includes a metallic core for strength and for providing a selected electrode surface on the end effector. Selectively conductive end effectors are manufactured by insert molding a plastic or ceramic or other non-conductive body around a metallic or otherwise conductive core. The conductive core is exposed on a selected portion of the working surface of the end effector and extends through the non-conductive body of the end effector for coupling to an electrical source. Selectively conductive end effectors of this type can also be manufactured by coating a cast end effector member with a non-conductive polymer or by metallically plating a non-conductive ceramic end effector member. By extending the conductive core of a selectively conductive end effector member to the pivot hole of the member, electrical coupling can be made through the clevis and tube of an endoscopic instrument. By extending the conductive core to the actuation bore of an end effector member, electrical coupling can be made through the push rod or other actuation member in an endoscopic instrument. Using both techniques, a bipolar selective cautery end effector can be provided on an endoscopic instrument.

摘要： A wire gripping handle for attaching to and detaching from wires defines a first tubular member, and a second tubular member which receives the first tubular member in generally coaxial relation. Both tubular members define a longitudinal slot so that, when the slots are aligned, a wire may be placed into the bores of the joined tubular members in lateral fashion. Then, upon relative rotation of the tubular members, a portion of one of them may be radially collapsed into gripping relation with the wire.
