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 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 for an endoscopic bioptome includes a pair of opposed end effectors having resilient arms formed from a super-elastic metal. The distal ends of the resilient arms terminate in end effector jaw cups which are also preferably formed from super-elastic metal, while the proximal portions of the resilient arms include angled portions which urge the jaw cups away from each other. The jaw cups are brought together into a biting action by a cylinder having a sharp distal edge which moves relative to and over he arms of the end effectors. As the resilient arms are formed from a super-elastic metal, they exhibit very high resiliency and durability even after numerous uses.

摘要： An endoscopic biopsy forceps has a detachable proximal handle portion and a distal portion which includes a pair of jaws mounted at the distal end of a flexible conduit. At least one pull wire extends through the conduit and is coupled to the jaws so that movement of the pull wire(s) through the conduit causes the jaws to open and close. The proximal end of the pull wire(s) is provided with a mating tip and the proximal end of the conduit is provided with a mating sleeve. The handle portion includes a shaft and a spool. The conduit is detachably attached to the shaft, while the pull wire(s) is detachably attached to the spool. Attachment is effected by spring biased coupling devices which engage the mating tip of the pull wire(s) and the mating sleeve of the conduit.

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 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.
摘要翻译：内窥镜器具设置有中空管，第一和第二端部执行器，其联接到中空管并且具有彼此偏离的臂，可滑动地设置在中空管上的圆柱形构件，延伸穿过管的推/拉线，联接到推/拉线和中空管的手柄组件，以及连接到推/拉线并通过在圆柱形构件中卷曲连接到圆柱形构件的盘段。当手柄组件被致动时，推/拉线相对于末端执行器移动盘段并因此移动圆柱形构件，并使圆柱形构件越过末端执行器的臂，从而迫使末端执行器关闭或允许打开。优选地，盘片段具有两个弯曲的侧面，其通过卷曲连接到圆柱形构件，并且两个基本平行的侧面为端部执行器的臂提供空间，使得盘片段能够相对于末端执行器移动。盘片段还包括用于接收推/拉线的中心孔。
