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.

摘要： A preferred apparatus for delivering an intravascular drug such as a sclerosing agent (or a microfoam sclerosing agent) to a varicose vein includes a catheter having three concentric tubes. The innermost tube has a guide wire lumen and an inflation lumen. The distal end of the innermost tube has an integral inflatable occlusion balloon in fluid communication with the inflation lumen. The intermediate tube has a lumen through which the innermost tube extends. The distal end of the intermediate tube has a self-expanding balloon with a plurality of fluid pores in fluid communication with the intermediate tube lumen. The outer tube has a lumen through which the intermediate tube extends. Sclerosing agent is dispensed through the intermediate tube to pores located at the distal end of the intermediate tube or in the self-expanding balloon. Veins are sclerosed as the self-expanding balloon is pulled through and ultimately out of the vein.

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： 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 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： 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.
摘要翻译：内窥镜多样本生物切割器包括中空的外部构件和从其延伸穿过的可轴向移动的内部构件。外部构件和内部构件的近端联接到致动器，用于相对于另一个轴向移动。外部构件的远端联接到具有尖锐远端边缘和钳口组件的圆柱体中的一个，而内部构件的远端联接到另一个。钳口组件包括一对相对的，优选有齿的钳口杯，每个钳口由弹性臂联接到基座构件。臂被弯曲以位于与基部构件的轴线相交的平面中并且将夹爪彼此分开定位。基座部件安装在气缸内，夹爪组件和气缸相对于彼此的轴向运动将臂插入气缸中，并使咬合杯以咬合动作一起接合。根据本发明，通过将每个钳口的切割边缘布置在与钳口臂的远端部分所在的平面相交的平面中，根据本发明增强了咬合动作。通过在钳口的外表面上设置关闭凸轮来进一步增强咬合动作，当闭合钳口时，该闭合凸轮由气缸接合。切割边缘的布置还呈现出内窥镜内部的光滑表面，并且闭合凸轮防止套筒完全滑过和夹紧夹爪。
