    摘要: A biopsy instrument and method of using such are provided wherein the biopsy instrument includes a proximal actuation handle, an elongate flexible member, and a distal assembly. The flexible member, connected to and extending from the actuation handle, includes an aspiration conduit for fluid connection with a vacuum source and for permitting the flow of fluid from the distal end to the proximal end of the biopsy instrument. The flexible member may include an irrigation conduit for supplying irrigation fluid to the distal end. The actuation handle includes a stationary member and an actuation device, and may include a sample chamber, a sample collector, valves for regulating the vacuum in the aspiration conduit and the fluid flow in the irrigation conduit, and a pressure increasing device for selectively increasing the pressure of the fluid supplied to the distal end. The distal assembly, coupled to the distal end of the flexible member, may be comprised of a movable jaw and a stationary jaw, or of first and second movable jaws. With the jaws in a closed position, the distal assembly may provide a substantially fluidtight passageway at the distal end of the aspiration conduit. The movable jaws are coupled to the actuation device, such that actuation of the actuation handle moves the movable jaws relative to the flexible member, thereby opening and closing the distal assembly.

    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 spring-biased 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: A bipolar push rod assembly is disclosed in conjunction with an endoscopic bipolar cautery scissors instrument. The push rod assembly has two conductive push rods which are substantially covered and insulated from each other by a double lumen flexible sheath. The proximal ends of the push rods are stabilized by an overmolded plastic collar and the distal ends of the push rods are stabilized by a ceramic insulator. The plastic collar is provided with a snap retainer for coupling it to a plastic plug retainer having a pair of spaced apart passages. A pair of female plug adapters are press fit onto the proximal ends of the push rods and are maintained in place by the plug retainer with each adaptor residing in a respective one of the passages. The distal ends of the push rods are swaged approximately 90.degree. in opposite directions. A ceramic insulator is disclosed as a one-piece unit into which the distal ends of the push rods are inserted. Another ceramic insulator is disclosed as a two-piece member which fits around the distal ends of the push rods. A double lumen sealing gasket which interrupts the double lumen sheath is also disclosed.
