  • Patent number: 9017372
    Abstract: A forceps includes first and second shafts, each having a jaw member disposed at a distal end thereof. At least one jaw member is moveable from an open to a closed position for grasping tissue therebetween. At least one jaw member is configured for reciprocation of a blade therethrough. A trigger assembly includes a trigger and at least one linkage coupled to the trigger and to the blade such that rotation of the trigger translates the blade between the retracted and the extended position. An interference member moveable between a locked position and an unlocked position is also provided. The interference member is configured to engage the linkage(s) when in the locked position to inhibit translation of the blade from the retracted to the extended position.

  • Patent number: 8316685
    Abstract: A pressing tool having a drive unit, a piston-cylinder unit with a fork-like receiver and an actual clamping pincer. The clamping pincer has a T-shaped mounting which, with a retaining bolt and a retaining bolt receiver, is connected to a fork-like receiver. In the fork-like receiver, a roller holder with two rollers is located. The fork-like receiver is part of the piston-cylinder unit. On actuation of the pressing tool, the piston-cylinder unit is pulled back and thus the roller holder with the rollers is moved forward relative thereto in an axial direction towards the clamping pincer. Thus, the rollers roll on roll flanks of the clamping jaws of the clamping pincer. The clamping pincer is pressed together by the rollers pressing apart the clamping jaws at the rear. Thus, the rollers are supported on a bearing block with sliding bearing surfaces.

    Abstract: A hand tool comprising a first handle member with integral jaw, a second handle member, and a third jaw member, all three members pivotally connected by a single common pivot pin. All three members are also cooperatively connected by a force multiplying mechanism, wherein an operative force applied to the handles is multiplied and applied to a work piece by the jaws. One embodiment of the invention features a “U”-shaped handle with two common pivot pin connection points, providing structural strength and handling stability. Other embodiments also comprise power assist devices to provide electrical and pneumatic work piece manipulation forces.

  • Patent number: 6142039
    Abstract: A bottle cap remover having a gripping head and an actuator. The gripping head has at least two pivotally mounted arms biased in a closed position, each arm having a respective gripping surface. Preferably the bottle cap remover has a neutral state, an insertion state, a bottle-gripping state, and a cap-removal state. The method for removing a bottle cap from a bottle using the bottle cap remover includes the first step of inserting a bottle and bottle cap between the gripping surfaces of the pivotally mounted arms by forcing the pivotally mounted arms into an at least partially open position. The next step is gripping the bottle cap between the gripping surfaces. The next step is to activate the actuator so that the actuator moves between a neutral position and an extreme position thereby pulling and removing the bottle cap from the bottle.

  • Patent number: 5507210
    Abstract: A toggle joint band wrench for an oil filter; comprises: A pair of side connectors bases which have three functional sets of systems connected between them to combine in functioning as a device. They are: (a) A set of toggle joint mechanisms connected pivotally between the upper parts to support the central toggle joint and its top handle on the top center of the device. (b) A clamping means connected between the middle pans to function for moving the side connectors closer or away from each other. (c) A pair of curved, laminated, toothed, clamping bands connected between the lower parts with a circular opening for an oil filter to be placed in-between them. A handle is connected to the top of the toggle joint pivotally. The clamping means can be adjusted to move the bands closer to each other in clamping and locking onto the oil filter. The toggle joint system keeps the handle constantly centralized. The handle can be flipped to be set on a lateral position in two positions across from each other.

  • Patent number: 5451231
    Abstract: A surgical staple extractor which has a gripping portion and a pair spaced-apart jaws and an anvil associated with the gripping portion. Structures are provided with the gripping portion for moving the anvil and the jaws in a scissor action to transfer forces from the anvil and jaws to a staple retained therebetween in order to mechanically deform or reform the staple for extraction from a patient. Cams are positioned between the jaws and the anvil for positively camming or displacing the jaws outwardly when the anvil jaws and jaws are operated. Actuation of the gripping portion results in moving the anvil and jaws with the cams interacting between the anvil and jaws for positively displacing the jaws outwardly in relation to the anvil for promoting controlled deformation of the staple in a removal path approximating the entry path thereby disengaging the staple from the patient.

  • Patent number: 5313857
    Abstract: The opener/closure of the present disclosure relates to devices permitting the opening or closing of twist cap containers. It comprises a rectangular housing in which a pair of cap gripping jaws are slidably mounted for movement toward and away from each other, and in which the jaws are interconnected by a cable in a manner whereby movement of one jaw in one direction is effective to move the other jaw in the opposite direction, whereby when moved toward each other both cooperate to grip a container twist cap either for loosening or tightening the cap to open or close its container. A standard positions the container below the housing by a strap tightly holding it securely against rotation as the jaws grip the cap, and the housing is manually rotated to loosen or tighten the cap on the container.

    Abstract: A system of pliers or the like, and "second bite" elements is disclosed. The pliers or the like are typically formed by at least two basic elements which are pivotally interconnected and which each have handle and jaw regions. Causing the handles of the pliers or the like to move toward one another also causes the jaws thereof to similarly move closer to one another by way of pliers action, or if an object is present between the jaws, more firmly grip the object. The second bite elements are pivotally attached to the end of one of the handles of the pliers or the like and interact with the other handle thereof to allow a user to more easily grip an object in the jaws of the pliers or the like by way of a force applied to the pliers or the like and the second bite elements.
