20090318954SYSTEM AND METHOD FOR ACTUATING A LAPAROSCOPIC SURGICAL INSTRUMENT - The invention is directed to a pin and slot design where the driving slots are moved from the tips to the actuation rod in one aspect of the invention.

This can be done because the area for the slots is not needed. Moreover, the usable area for the drive slots on the blade or tip of the actuation rod is maximized to the overall diameter of the outer tube or shaft which provides additional leverage to the blades or tips. In addition, the depth of each slot can be varied such that during actuation, increased tension can be put on the blades or tips throughout the cut. More specifically, the surgical instrument of the invention comprises an elongate tube extending along an axis including an actuation rod coaxially slidable within the elongate tube, a first tip including a first pin formed on a proximal end surface of the first tip, and a second tip including a second pin formed on a proximal end surface of the second tip, the second tip pivotally connected to the first tip at a common pivot pin operably connected to the elongate tube to open and close the tips in response to movement of the actuation rod.

20120004685Surgical Instrument - In a surgical instrument with two legs movable relative to each other, a tip inserted in a receiving space at the distal end of the leg being exchangeably held at the free end of the legs, with a fixing device for releasable fixation to the leg, the fixing device comprising on one of the two parts two locking arms which are arranged next to each other and are elastically bendable apart, and comprising on the other one of the two parts a locking projection extending into the leg transversely to the direction of insertion of the tip, the locking projection, when inserting the tip into the receiving space of the leg, engaging between the two locking arms, bending these elastically apart, and at the end of the inserting movement, entering a recess on the inner side of the locking arms, so that the locking arms approach each other again after they have been elastically bent apart, in order to simplify the structure and, in particular, to reduce soiling and risk of injury, it is proposed that the receiving space widen in the proximal direction from its insertion end.01-05-2012

20130211446Medical Instrument - A medical instrument having a force-limiting apparatus that, upon reaching the borderline force, ensures maintenance of the applied resistance force. It is proposed that the force-limiting apparatus should include a housing in which two components that can move in opposite directions to one another in the longitudinal direction of the housing are disposed in such a way that both components are disposed so that they can slide axially in the housing against the force of at least one spring element disposed in the housing, such that the two components are coupled with one another by at least one force transmission element that is acting on both components.08-15-2013
