Embodiment Construction

[0041] The surgical clamp according to a preferred embodiment of the invention comprises two clamp branches 1 and a bending spring or a bending spring (series) arrangement 6 connecting the clamp branches 1, each clamp branch 1 being formed by at least a clamping part 2 and a clamping part 2. The actuating part 4 is formed, the bending spring or the bending spring (series) arrangement 6 is preferably in a C-shape, U-shape or V-shape, at least in part areas along the actuating part 4 (in / between the actuating parts 4) towards The clamping portion 2 is concave or convex.

[0042] according to figure 1 The clamping portion 2 of each clamping branch 1 comprises a substantially straight elongated clamping rod 2a, which is preferably toothed or at the side facing the other clamping rod 2a (not shown in detail). Ripples are provided on the sides. However, the clamping portion may also be configured with a rough surface or with only a smooth (raw) surface. The clamping portion 2 may...

Abstract

The invention discloses a surgical clamp, which comprises two clamp branches (1) and a curved spring arrangement (6), and the two clamp branches (1) are respectively controlled by a clamping part (2 ) and an actuating part (4), the two clamp branches (1) are preferably coupled to each other in a single piece of material by means of the bending spring arrangement (6). According to the invention, the bending spring arrangement (6) comprises coupling means by means of which selected parts of the bending spring arrangement (6) can be short-circuited for spring bias and possibly for changing (preferably reducing ) the effective total spring length of the bending spring setting (6).

Description

technical field [0001] The invention relates to a surgical clamp (in particular a one-piece aneurysm clamp) according to the preamble of claim 1 . Background technique [0002] Surgical clamps (or also called tissue clamps) are medically implanted devices, used in most cases, for example, to temporarily close tissue perforations, or as vascular clamps for the treatment of aneurysms. To this end, multiple jaws shapes are suitable starting from jaw jaws up to row (straight) jaws where the gripping or jaws branch into two opposing rows similar to the upper and lower jaws. In the form of longitudinally curved teeth, the gripping or tong branches are coupled to each other by hinges at their respective two longitudinal ends, the row (straight) tongs are equivalent to conventional tweezers, comprising two opposing substantially The straight clamping crossbars, the clamping appendages are provided with teeth or corrugations and are hingedly coupled to one another, where appropriate...
