Apr 7, 2000 - Karl Storz GmbH & Co. KG
What is described here is an instrument for medical and particularly endoscopic applications, comprising a proximally disposed operating unit, a distally disposed multi-part functional element having individual parts which are jointly and additionally independently movable, such as a multi-part forceps jaw, and an elongate connecting part which is disposed between the operating unit and said forceps jaw. The invention is characterized by the provisions that said operating unit is so configured that it can be grasped around by one hand, and that said operating unit comprises at least two pivotable and/or tiltable elements which are a component of the surface of said operating unit and which, when moving, control each one part of said multi-part functional element.
FIGS. 3a-3c are sectional views taken through the operating unit for an explanation of the mode of operation, and
FIGS. 4a-4c show a perspective illustration of an example of the interior structure of the second embodiment.
The mode of operation of the second embodiment will now be explained with reference to the sectional views shown in FIGS. 3a-3c.
FIGS. 3a to 3c show different positions of the operating element, with equal parts being provided with equal reference numerals.
FIGS. 4a-4c illustrate a forceps jaw assembly as an example of a conceivable functional element in various positions, i.e. in the closed position (FIG. 4a), the completely open position (FIG. 4b), and in a position in which, for instance, a tract of tissue can be enclosed (FIG. 4c).
Two transmitting rods 11 and 12 are provided in the connecting part 1, whereof the rod 12 has a tubular design and surrounds the rod 11. A displacement of the rod 11 privots an element 4 which thereby moving opens or closes the parts 1, respectively. A displacement of the rod 12 causes, via a linkage 5, the parts 2 to move relative to the parts 1 so that the parts 2 of the forceps jaw assembly, which are disposed on the distal side, can be moved independently of the parts 1 disposed on the proximal side. This is illustrated in FIGS. 4a to 4c.
