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 biopsy forceps instrument includes a distal jaws assembly detachable from a proximal handle assembly. The proximal handle assembly includes a centrally slotted shaft and a spool having a laterally seated cross block which passes through the central slot. The distal jaws assembly includes jaws mounted on a clevis at the distal end of a coil and coupled to a pull wire which extends through the coil to its proximal end. The proximal end of the coil is provided with a connecting sleeve provided with a frustoconical portion having double-helical threads for removably coupling the coil to a shaft having a distal frustoconical portion having double-helical threads. The proximal end of the pull wire is provided with a grooved mating member and the spool is provided with a locking assembly having a springbiased push button latch for releasably engaging the grooved mating member. The grooved mating member has an elongate cylindrical distal portion, a central cylindrical portion having a relatively larger diameter, a proximal cylindrical grooved portion, and a proximal conical portion having a rounded apex. The elongate distal portion has a bore into which the pull wire is secured. The mating member end of the pull wire can be snapped into the locking assembly and the coil can be quickly and securely coupled to the shaft.

摘要： An endoscopic surgical instrument includes a proximal handle assembly coupled to a relatively long coil and to a relatively long pull wire extending through the long coil, and a distal jaw assembly coupled to a relatively short coil and to a relatively short pull wire extending through the short coil. The distal ends of the long coil and pull wire are provided with a first coupling device and the proximal ends of the short coil and pull wire are provided with a second coupling device which is mateable with the first coupling device. The first and second coupling devices couple the distal end of the long coil with the proximal end of the short coil and the distal end of the long pull wire with the proximal end of the short pull wire. The presently preferred pull wire coupling includes a ball and socket coupling and the presently preferred coil coupling includes a bayonet coupling. A rigid endoscopic surgical instrument with a detachable end effector assembly is also disclosed. The design of the coupling devices permits the coupling devices to be relatively small, having an overall outer diameter of two to three millimeters.

摘要： An actuator for an endoscopic instrument includes a handle having a through bore with a distal keyway and a lever which is pivotally coupled to the handle. A proximal tube sleeve is insert molded or press fit to the proximal end of the instrument tube. The tube sleeve has a pair of ramped thread-like projections and a pair of distally facing wedge-like projections all of which pass through the keyway in the handle. A proximal stop ring on the tube sleeve prevents the tube sleeve from passing completely through the handle. A ferrule having a pair of interior threadlike projections threadably engages the tube sleeve and is frictionally engaged by the wedge-like projections. A ferrule locking cap having a proximal inner groove and a distal flange fits in the annular space between the tube sleeve and the ferrule. The proximal groove engages a locking ring on the tube sleeve and splines on the tube sleeve and the ferrule frictionally engage the cap. The tube sleeve and the ferrule engage the cap with some friction so that the tube may be rotated relative to the handle but will not rotate relative to the ferrule.

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 the 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. Where the endoscopic instrument is a biopsy forceps type instrument having a long coil, the threaded portion of the screw mates naturally with the distal end of the coil, and the end effectors, which are normally biased away from each other, are closed by a cylinder which is moved over the arms of the end effectors. Where the endoscopic instrument is a laparoscopic type instrument, an inner rod of the instrument is provided with threads to receive the screw, and the end effectors are closed either by the outer tube of the instrument which is slid over the arms of the end effectors, or by pulling the inner rod into the outer tube.

The proximal ends of the outer and inner members are coupled to an actuator for axially displacing one relative to the other.

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 surgical instrument includes a proximal handle with a distally extending lever actuator. The handle and lever actuator are coupled by a tube and push rod to a pair of distal end effectors. The proximal end of the tube is mounted in a bushing having a flange which is freely rotatable within a flange receiving recess in the handle. The proximal end of the push rod extends proximally beyond the bushing and is coupled to the lever actuator by a ball and set screw coupling. The lever actuator preferably extends at least four inches distally from the proximal end of the handle and includes a finger ring near its distal end. The tube is preferably provided with a ferrule immediately distal of the handle for rotating the tube and push rod about the longitudinal axis of the instrument. The ferrule is preferably provided with a distal extension having an annular notch for locking engagement inside another endoscopic instrument. The lever actuator imparts a force to the end effectors which is magnified relative to the force applied to the actuator. The distal extension of the lever actuator and the finger ring allow the instrument to be operated with one finger while the instrument is grasped by the ferrule or mounted inside another endoscopic instrument.
