摘要： An endoscopic bipolar cautery biopsy forceps device has a conduit, a pair of articulable opposed jaws, two conductive pull wires, and an actuator. The articulable opposed jaws are located at the distal end of the conduit. Each jaw is provided with a cutting surface at its distal end and a tang at its proximal end. At least a portion of the cutting surface is electrically conductive and a portion of the tang is electrically conductive and electrically coupled to the conductive cutting surface. The remainder of the jaw is preferably non-conductive or is coated with an insulator. The conductive pull wire is coupled to the conductive portion of the tang of each jaw and is insulated as it extends through the conduit to a handle portion which includes the actuator. The actuator is coupled to the proximal ends of the pull wires so that movement of the actuator pulls the pull wires and articulates the jaws. The actuator is also provided with an electrical coupling device which electrically couples to the proximal ends of the pull wires and permits easy connection to an electrical cautery source.

摘要： An endoscopic scissors includes a clevis having a relatively large diameter bore in its first arm and relatively smaller diameter bore in its second arm. A pair of scissor elements having mounting/pivot holes are mounted between the clevis arms. Either the small diameter bore in the second clevis arm or the mounting/pivot hole in the scissor element closest to the second clevis arm is threaded. A stepped diameter axle pin having a threaded portion is inserted with its smaller end entering the larger diameter bore of the first clevis arm. The threaded portion of the axle pin threadably engages either the threaded bore in the second clevis arm or the threaded mounting/pivot hole of the scissor element closest to the second clevis arm. In one embodiment, the bore in the second clevis arm is not threaded and the threaded portion of the axle pin engages only the threaded threaded mounting/pivot hole of the scissor element closest to the second clevis arm. Both ends of the axle pin float in respective clevis arm bores. In another embodiment where the scissor element closest to the second clevis arm is kept stationary, the threaded portion of the axle pin engages the threaded bore in the second clevis arm. The larger end of the axle pin floats in the large diameter bore of the first clevis arm. In a third embodiment, a washer is placed between the second clevis arm and the scissor element closest to it and the axle pin engages the threaded bore in the second clevis arm.

摘要： Various embodiments of flexible plastic tubing are disclosed for connection to an endoscopic instrument having suction, irrigation and electrocautery capabilities, with the electrocautery capability requiring connection to an electrical wire. Generally, the tubing is an integral, extruded flexible plastic tube having a first suction portion with a first interior cylindrical passageway, a second irrigation portion with a second interior cylindrical passageway, and a third portion with a third passageway for the electrical wire. The third portion joins the other portions. The third portion has a substantially cylindrical interior passageway with first and second flexible lips defining a peripheral opening which is narrower than the electrical wire such that the electrical wire is inserted past the lips and held in the passageway and is removable from the passageway.

摘要： Surgical instruments for insertion through trocar tubes are disclosed. The instruments broadly include: a hollow tube; a clevis which is formed separately from the tube with the distal end of the hollow tube crimped around the proximal end of the clevis, and with the clevis including a pivot pin; at least one end effector element having a pivot hole through which the pivot pin of the clevis is pivotally engaged, and another through-hole; a push rod extending at least partially through the hollow tube and mechanically coupled to the end effector element; and a plastic actuator engaging the proximal end of the push rod and for imparting reciprocal motion to the push rod relative to the tube, where the reciprocal motion is translated at the clevis into pivotal motion of the end effector element. Preferably, staple-like connectors are used to mechanically couple the end effector element to the push rod, especially for double acting instruments. The end effector elements are preferably formed of investment cast bronze.

摘要： An endoscopic surgical scissors instrument is provided with end effectors having arcuate cammed surfaces proximal their pivot points. The instrument includes a pair of scissor blades coupled to a pivot post such that at least one blade is pivotally movable with respect to the other from an open position to a closed position. The blades have inside cutting edges which engage each other in bearing contact as the blades are moved from the open to the closed position. In addition, each blade is bowed so as to effect a biasing of the cutting edges together in positions near the closed position. The arcuate cammed surface on the blades are located behind the pivot post, and the cammed surfaces push the blades apart behind the pivot post, thereby urging the cutting edges in front of the pivot post together in the open position of the blades. The cammed surfaces are arranged so that they exert a progressive biasing of the cutting edges together with the most biasing when the blades are in the open position and the least biasing when the blades are in the closed position. By requiring the cams to be arcuate, the cams contact each other in many locations as they slide over each other, thereby reducing wear and increasing stability.
摘要翻译：内窥镜手术剪刀仪器具有在其枢转点附近具有弓形凸轮表面的末端执行器。仪器包括一对联接到枢轴柱的剪刀片，使得至少一个刀片可相对于另一个刀片从打开位置枢转地移动到关闭位置。叶片具有在叶片从开放状态移动到关闭位置时轴承接触的彼此啮合的内侧切割刃。此外，每个刀片都是弯曲的，以便在靠近关闭位置的位置实现切削刃的偏置。刀片上的弧形凸轮表面位于枢轴柱后面，并且凸轮表面将刀片推到枢转柱后方，从而将刀片前端的切削刃推到刀片的打开位置。凸轮表面布置成使得当叶片处于打开位置时，它们与最大偏压一起施加切削刃的渐进偏置，并且当叶片处于关闭位置时最小偏压。通过要求凸轮为弧形，凸轮在彼此滑动时在许多位置彼此接触，从而减少磨损并提高稳定性。

摘要： Surgical instruments of the invention are provided with distal ends having a clevis and two discrete investment cast end effectors. One end effector is stationary relative to the clevis, and the other moves or rotates about a transverse pin of the clevis. The rotating end effector 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 which is either directly coupled to the proximal end of the rotating end effector or coupled by a staple element. On the other hand, the stationary second end effector, while including a first hole through which the transverse pin extends, has a boss which preferably engages a hole 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.

摘要： An actuator for a laparoscopic surgical instrument imparts reciprocal motion to a push rod surrounded by a hollow tube. The actuator includes a plastic housing which fixedly engages the hollow tube, and a lever which fixedly engages the push rod and pivotally engages the housing. The housing also preferably includes an integral handle. When the handle and lever are manipulated by the user such as by pivotal movement of the lever, reciprocal motion is imparted to the push rod relative to the hollow tube. The lever also includes an external unevenly surfaced portion which when frictionally engaged by a digit of a human hand will impart pivotal motion to the lever, and hence reciprocal motion to the push rod.
