Pincer-like needle holders and clamps

The innovation "relates to pincer-like needle holders and clamps for surgical use, with crossed arms consisting of a jaw and a branch are formed as a handle, which is used to hold the joint via a jaw part and branch in each case in the pivot plane widening conclusion in the form of a female end part and one opposite constricted male tail.

Instruments of this type are known in many forms. It is necessary here that they are next to must have a low weight and high strength in order to meet the requirements to become. In practice, deficiencies have shown that in the known instruments by sharp-edged Transitions between tail and mouth part or

Industry through the occurring high loads there is a risk of breakage «Furthermore, it comes from the right-angled to the pivot plane formed transitions to clamping points that the sewing thread jams during sewing or * even tears.

The task of the innovation is to provide a functionally reliable instrument of the generic type in a simple manner Art to create a favorable flow of forces in highly stressed areas to prevent breakage and prevents jamming of the suture material.

The object is achieved according to the invention in that the transitions, in particular between male final part and Mauiteil as well as branch, in the pivot plane are arcuate and that at right angles to the pivot plane between the male end part and the mouth part and branch in each case an arcuate transition with a recess formed in the closed position to the female end part are arranged.

As a result, no edges are formed which tend to tear under stress and which are additional jamming or entanglement of the suture material, which can lead to tearing, is excluded. Furthermore, through a training in accordance with the innovation, in which no Edges are present, which facilitates the cleaning process required in the surgical field.

A needle holder is shown schematically in the drawing. Show it:

The constricted male end part 13 is also rectangular to the pivot plane 10 in the transition area | extend with a radius 16 and form § a recess 17, which remains free in the closed position, to the female end part 12,
