摘要： An endoscopic bipolar cautery biopsy forceps device has a conduit, a pair of articulable opposed jaws, two conductive pull wires, and an actuator. The articulable opposed jaws are located at the distal end of the conduit. Each jaw is provided with a cutting surface at its distal end and a tang at its proximal end. At least a portion of the cutting surface is electrically conductive and a portion of the tang is electrically conductive and electrically coupled to the conductive cutting surface. The remainder of the jaw is preferably non-conductive or is coated with an insulator. The conductive pull wire is coupled to the conductive portion of the tang of each jaw and is insulated as it extends through the conduit to a handle portion which includes the actuator. The actuator is coupled to the proximal ends of the pull wires so that movement of the actuator pulls the pull wires and articulates the jaws. The actuator is also provided with an electrical coupling device which electrically couples to the proximal ends of the pull wires and permits easy connection to an electrical cautery source.

摘要： Endoscopic biopsy forceps jaws having an outer edge which may be generally U-shaped, circular, or oblate circular are disclosed with teeth which extend completely around the outer edge. The teeth may take any of several arrangements. In a first arrangement, the teeth and valleys are formed with two substantially rectangular surfaces which meet at substantially horizontal vertex and nadir lines. In a second arrangement, each tooth has a vertex or peak located upward and inward from the outer edge, and is defined by a substantially triangular inner surface, a substantially quadrilateral base, and a surface which extends outward and downward from the vertex of the triangular surface to the outer edge of the jaw. Valleys between the teeth have two inclined surfaces which intersect along a line which extends inward and downward from the outer edge of the jaw. In a third arrangement, the peak of each tooth is defined by the vertex of a pyramid having four faces and valleys between these teeth have three substantially flat surfaces which intersect at a vertex which lies downward and inward from the outer edge of the jaw. Alternate embodiments of all arrangements include providing a lip around the outer portion of the outer edge so that the teeth and valleys are spaced farther in from the outer surface of the jaw cup.

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： An endoscopic instrument is provided with a hollow tube, first and second end effectors coupled to the hollow tube and having arms biased away from each other, a cylindrical member slidably disposed over the hollow tube, a push/pull wire extending through the tube, a handle assembly coupled to the push/pull wire and the hollow tube, and a disk segment connected to the push/pull wire and connected to the cylindrical member by a crimp in the cylindrical member. When the handle assembly is actuated, the push/pull wire moves the disk segment and hence the cylindrical member relative to the end effectors and causes the cylindrical member to ride over the arms of the end effectors, thereby forcing the end effectors closed or permitting them to open. Preferably, the disk segment has two curved sides which are coupled to the cylindrical member by crimping, and two substantially parallel sides which provide room for the arms of the end effectors so that the disk segment can move relative to the end effectors. The disk segment also includes a central bore for receiving the push/pull wire.

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.
