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 urge the jaws away 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. When the outer member is coupled to the jaw assembly and the inner member is coupled to the cylinder, the distal end of the inner member is preferably coupled to the cylinder by a bent end which is welded to a hole in the cylinder wall. One of the jaws is preferably larger and has a pair of proximal wings. The wings and an upper edge portion of the larger jaw are bent radially inward and enter the smaller jaw when the jaws are closed.

摘要： An endoscopic bipolar electrocautery instrument includes a proximal actuator coupled by a tube and push rod to a pair of distal graspers. The tube is covered with an insulating shrink wrap from its distal end up to an uncovered proximal portion. A stationary jaw with an integral clevis is mounted inside the distal end of the tube and electrically contacts the inner surface thereof. The clevis holds a pair of ceramic insulators between which a movable jaw is mounted on an insulated bushing with an axle pin. The movable jaw is electrically and mechanically coupled to the push rod which is covered with an insulating shrink wrap from a point just proximal of its connection with the movable jaw to a point near its proximal end. The uninsulated proximal end of the tube is mounted in a conductive bushing which rotates within a nonconductive handle. The proximal end of the push rod extends beyond the conductive bushing and a rubber insulator is fitted between the bushing and the push rod. A nonconductive actuating lever is hingedly attached to the handle and the push rod is rotatingly coupled thereto. A pair of Y-shaped electrical wiper contacts are insert molded in a nonconductive member mounted in the handle and respectively contact the bushing and uninsulated portion of the push rod on either side of the rubber insulator. A bipolar cable insert molded in the nonconductive member is coupled to these contacts and to a source of current.

摘要： A double acting bipolar endoscopic scissors includes a hollow tube with an integral clevis and a bipolar push rod extending therethrough. The tube is rotatably mounted in a handle member which is provided with a manual actuation lever. The bipolar push rod includes a pair of spaced apart rods which are insulated along substantially their entire lengths by polypropylene sheaths, and which are insert molded in a distal insulating collar near their distal ends, in a proximal insulating collar near their proximal ends, and in a plurality of non-conductive cylinders therebetween. The distal collar includes a flattened distal portion and the distal ends of the rods are bent approximately 90 degrees and exit the flattened portion. A pair of scissor blades are mounted in the clevis with an axle screw and a nut and are insulated from the clevis and the axle screw. One of the scissor blades has a ceramic coating on its face to insulate it from the other scissor blade. Proximal tangs of the scissor blades are coupled by links to the bent distal ends of the rods which extend from the flattened portion of the distal collar.

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 jaw assembly of an endoscopic biotome is formed by cutting a hemispherical end of a spring metal cylinder with electrical discharge or laser machining equipment to provide opposed jaw cups. Metal is cut from the middle portion of the cylinder to form two tapered arms which terminate at a cylindrical portion of the open end of the cylinder. At least one of the two tapered arms is bent away from the other to form the jaw assembly.
