摘要： A jaw assembly (12, 14) for an endoscopic bioptome includes a pair of opposed end effectors (44a, 44b) having resilient arms (50a, 50b) formed from a super-elastic metal. The distal ends of the resilient arms (50a, 50b) terminate in end effector jaw cups (46a, 46b) which are also preferably formed from super-elastic metal, while the proximal portions (51a, 51b) of the resilient arms (50a, 50b) include angled portions (52a, 52b) which urge the jaw cups (46a, 46b) away from each other. The jaw cups (46a, 46b) are brought together into a biting action by a cylinder (40) having a sharp distal edge (42) which moves relative to and over the arms (50a, 50b) of the end effectors (44a, 44b). As the resilient arms (50a, 50b) are formed from a super-elastic metal, they exhibit very high resiliency and durability even after numerous uses.

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 (390) for use in an endoscopic surgical tool (50) includes a metallic core (304) for strength and for providing a selected electrode surface (305) on the end effector (390). Selectively conductive end effectors (390) are manufactured by insert molding a plastic or ceramic or other nonconductive body around a metallic or otherwise conductive core (304). The conductive core (304) is exposed on a selected portion of the working surface (302) of the end effector (390) and extends through the nonconductive body of the end effector (390) for coupling to an electrical source. Selectively conductive end effectors (390) of this type can also be manufactured by coating a cast end effector member with a nonconductive polymer or by metallically plating a nonconductive ceramic end effector member. By extending the conductive core (304) of a selectively conductive end effector member (390) to the pivot hole (306) of the member, electrical coupling can be made through the clevis (30) and tube (15) of an endoscopic instrument (50).

摘要： An apparatus for counting the number of times a temperature cycle occurs includes an indicator having sequential indicia and a temperature responsive member for indicating a next one of the indicia. Mechanical, fluid mechanical and electronic versions of the invention are disclosed. In the mechanical version, the indicator can be a ratchet member having teeth, a pawl and a display surface containing indicia. A temperature responsive element such as a bimetallic member engages the teeth of the ratchet and advances the ratchet each time the apparatus is subjected to a preset temperature cycle. A housing with a window masks the display to indicate one of the indicia as advanced by the temperature responsive element. Preferred embodiments of the mechanical version include a ring-like ratchet member with interior teeth and an exterior display surface. The number of teeth is preferably one or more less than the number of indicia so that upon advancing the ratchet member to the last indicia, it can be advanced no further. The bimetallic element is mounted inside the ring and the housing covers the outer surface of the ring. A removable locking pin is provided to prevent movement of the ratchet member until activated.

摘要： An apparatus for counting the number of times a medical instrument has been sterilized includes an indicator (10) having sequential indicia (26) and a heat responsive member (18) for indicating a next one of the indicia. Mechanical, fluid mechanical and electronic versions, the indicator (10) can be ratchet member (16) having teeth (30), and a display surface (21) containing indicia (26). A heat responsive element such as a bimetallic member (18) engages the teeth (30) of the ratchet (16) and advances the ratchet each time the apparatus is subjected to the heat of sterilization. A housing (12) with a window (14) masks the display to indicate one of the indicia as advanced by the heat responsive element. A locking and/or disabling pin (38) can be provided to prevent movement of the ratchet member during shipping and/or to disable the instrument after a predetermined number of sterilizations.

摘要： Surgical instruments of the invention are provided with distal ends having a clevis (20) and two discrete investment cast end effectors (90, 92). One end effector (92) is stationary relative to the clevis, and the other moves or rotates about a transverse pin (45) of the clevis. The rotating end effector (90) includes a first hole through which the transverse pin extends, and the surgical instrument includes an actuation mechanism for causing the rotating end effector to rotate about the transverse pin. The actuation mechanism preferably includes a push rod (60) which is either directly coupled to the proximal end of the rotating end effector or coupled by a link element (97). On the other hand, the stationary second end effector, while including a first hole through which the transverse pin extends, has a boss (46) which preferably engages a hole (46') in the clevis and is not coupled to the actuation mechanism. With the clevis and second end effector being coupled at two locations, the second end effector is not free to rotate about the clevis pin, but is held stationary. Other manners of holding the second end effector stationary are to provide the clevis with a boss, and the stationary end effector with a second hole into which the boss extends, or to provide another pin which extends through one arm of the clevis and the stationary end effector only.
