  • Patent number: 11690622
    Abstract: A surgical clamp for laparoscopic or endoscopic surgeries provides autonomous adjustable pressure and placement with a releasable or integrated remote manipulator. Two jaws move simultaneously with respect to the main body of the clamp to open and close to secure or release tissue and/or organs. In a first embodiment, the instrument is made up of two separable components; a remote manipulator component, and a releasable adjustable pressure clamp component that is linked or separated at an interlocking connection point. The main body of the clamp includes a central tubular port through which a pressure bar passes. An assembly of cam arms connects the push rod to jaws, allowing for symmetrical and simultaneous actuation. A compression spring is positioned around the pressure bar and is secured by an adjustable nut on the threaded end of the pressure bar. Adjustment varies the compressive force of the spring and thereby the gripping force.

  • Patent number: 7533893
    Abstract: An auxiliary suspension system operating on stages of loaded rubber for axles of vehicles in general includes a pair of concentric tubes, one outer and one inner, with rubber applied to the surfaces of contact. As the tubes turn one inside the other, they put the rubber into torsion. The system can have two integrated phases or it can be a hybrid system. The suspension system connects the vehicle chassis to the axle of the wheels using a lever arm attached to the outer tube and a support that holds the inner tube and a system of torsion control at the other end.

  • Publication number: 20040245740
    Abstract: Auxiliary suspension on work phases of tension rubber for shaft of vehicles in general includes a pair of concentrical tubes, one outer and other one inner with rubber added on its surfaces of contact, which one turn one inside the other one, they put the rubber into tension efforts, this system can have two phases interbuilt or it can be hybrid, this suspension unites vehicle chassis to wheels shaft using a lever arm solded to outer tube and a supporting that holds inner tube and a system of tension control in the other extreme, and has characteristics like tension lever that changes longitudinal movement of tensor into angular movement that transmits to anchoring tube to stretch rubber and a tension arm or crossbeam that it is fixed to covering box into an extreme and that has a drilling where a tensor with forked stake passes and it gives a supporting point to tensor to serve to generate a longitudinal movement to permit to adjust tension of rubber at a lever wished.
