Abstract: A laparoscopic surgical instrument is provided with a manual gripping portion provided with three gripping members, one of them being fixed (non-movable) and the other two gripping members being movable and hinged such that each can perform an angular movement, facilitating the use of the tool during surgery.

Abstract: The invention relates to a tool including a pair of jaws (3) interacting with one another by means of actuating means comprising a central stationary portion and two cam plates (4) arranged such that said plates are facing both sides of the central stationary part, which are slidable on said central stationary part. The two cam plates being associated with a shaft for driving linear movement, the jaws being coupled to the central stationary part and the two cam plates (4). Thus, during a forward movement of the cam plates, said plates cause a linear movement away from one jaw respective to the other, during a backward movement thereof, said cam plates (4) cause a linear movement for moving one of the jaws (3) closer to the other.

Abstract: The invention relates to a completely mechanical laparoscopic surgical instrument which can be disposed of after a single use or which can be sterilized and re-used more than once. The instrument essentially comprises: a gripping zone provided with two gripping elements (2, 3) hinged to one another by means of a pivot shaft (4), a working tool (30) provided with two jaws hinged to one another by means of a pivot shaft, and an actuation mechanism that can transmit movement from the gripping zone to the working tool (30). According to the invention, the tool can adopt multiple positions and/or orientations during its use with the assistance of substantially annular bodies that are coupled to connecting rods associated with the gripping elements.

Abstract: The invention relates to a portable stand-alone device (1), particularly suitable for use in surgery, micro-component handling and the like. The invention comprises: a micro-tool that can be removably coupled to a main casing (3); and actuation means for handling the micro-tool (2), associated with servomotors. The aforementioned actuation means comprise: a first actuator associated with a first servomotor (4), providing the micro-tool (2) with a degree of rotational freedom; a second actuator associated with a second servomotor and connected to the first actuator in order to move the micro-tool forwards and backwards in translation; and a third actuator (6) associated with a third servomotor, which oscillates the micro-tool in relation to the longitudinal axis of the first and second actuators. The first, second and third actuators are associated with a control unit (7) for determining the position of the micro-tool in space.
