Abstract: A medical-technical instrument includes a first instrument branch, a second instrument branch, and a bearing element coupling the instrument branches in a superimposed closure. The branches contact each other in a closure portion in an operation pivot region via mutually facing contact surfaces so that the branches in the operation pivot region contact each other with their respective contact surfaces, and the branches are positionable in a cleaning position outside the operation pivot region. The bearing element is fixed at an end portion on the first instrument branch and has a head widening conically in a continuous or stepped manner. The head penetrates a continuously or stepped conical passage opening in the second instrument branch. The passage opening is an elongated hole, and the bearing element is rotatably positionable in the elongated hole and translationally fixedly received.

Abstract: An instrument comprises a headpiece at a proximal end, a shaft connected to said headpiece, said shaft can be deflected at least in a distal end area thereof. A deflection mechanism is provided for deflecting said shaft. Said deflection mechanism has control wires and a control element for controlling a deflection movement of said deflection mechanism. A lock is provided for locking said deflection mechanism. Said lock has a catch mechanism connected to said control element in such a way that said catch mechanism, without actuation, is automatically forced into a locking position and a movement of said control element first opens said catch mechanism and only then permits a deflection of said shaft. A release of said control element in any position of said deflection mechanism causes an enforced locking by said catch mechanism in said position.
