A medical instrument for grasping an object, in particular a surgical needle holder, including an elongated shaft, two jaw parts arranged at a distal end of the shaft, at least one of the jaw parts being pivotable with respect to the other of the jaw parts between a grasp state for grasping the object between the jaw parts and a release state for releasing the object. A handle is arranged at a proximal end of the shaft and has at least one operating element for moving the at least one pivotable jaw part between the grasp state and the release state via an axially movable force transmission element operatively connected with the at least one operating element and with the at least one pivotable jaw part via an articulated joint. The instrument further includes a latching mechanism for immobilizing the at least one pivotable jaw part in the grasp state.

Medical instrument for grasping an object, in particular needle holder

The invention relates to a medical grasping and holding instrument with a handle consisting of two handgrips and with a holding portion that consists of at least two jaw members and can be activated by the handle. The jaw members of the holding portion can be locked by means of a spring element both in an end position that releases the holding portion and in an end position that locks the holding portion. In order to create a medical grasping and holding instrument that is of simple construction, can be operated with just one hand, and is easy to clean, it is proposed with this invention that the spring element, configured as a flat spring, for locking the jaw members in their end positions is mounted between the handgrips of the handle so as to connect the two handgrips to one another in such a way that the spring element can be moved by way of a bearing point of a handgrip at the spring element between two end positions that release the spring element.

Medical grasping and holding instrument

The invention relates to a medical instrument, in particular an endoscopic instrument, with an instrument shaft, a tool positioned on the distal end of the instrument shaft, and a handle, which can be secured on the instrument shaft so that it can be moved in an axial extension of the instrument shaft. In order to create an instrument which makes possible a comfortable, safe, and reliable handling even with the most varied application purposes, it is proposed with the invention that the handle can be secured on the instrument shaft so that it can be moved by at least one degree of freedom with respect to the instrument shaft.
