Embodiment Construction

[0045] The drawings are merely schematic in nature and are intended exclusively for the understanding of the invention. Identical elements are marked with the same reference symbols.

[0046] figure 1 and figure 2 A surgical device 1 according to a preferred embodiment of the invention is shown. The device 1 has a main body or technical block 2 to which a flexible articulated arm 3 is attached. A holding element 4 is arranged at the free distal end of the articulated arm 3 . The technical block 2 basically contains the entire technical system for tightening the articulated arm 3 and the fixing device 5 for fixing the whole system to an external support not shown. The technical block 2 constitutes a reusable technical module, and the articulated arm 3 together with the holding element 4 constitutes a working module designed for one-time use. The articulating arm 3 includes a plurality of hemispherical articulating arm segments 6, and a pulling cable 7 passes through the c...

Abstract

The invention relates to a surgical device (1) for stabilizing tissue or positioning organs during surgical intervention, or for positioning and holding surgical instruments and devices, comprising: a main body (2) and a flexible arm (3), in particular an articulated arm , the flexible arm is in particular fastened or can be fastened to the main body (2), the flexible arm can be brought to different positions and / or places and can be locked in a desired position by a tightening mechanism, tightening The mechanism is tightened and / or released automatically and / or by means of an energy source, and wherein, in the locked state of the flexible arm (3), the tightening mechanism has a retightening reserve (ΔR), in particular a retightening reserve stroke (ΔR), and the flexible arm (3) is able to automatically retighten in order to maintain its locked state, in particular autonomously by introducing energy from an energy source or by utilizing the retightening reserve (ΔR). The invention also relates to a retensioning mechanism for a surgical working arm.

Description

technical field [0001] The present invention relates to a surgical device for stabilizing tissue or for positioning organs or for positioning and holding surgical instruments and equipment during surgical interventions, comprising a main body and a flexible arm, in particular an articulated arm, which is particularly tightened Fixed to the main body or can be fastened to the main body, the flexible arm can be brought to different positions and / or places, and can be locked in a desired position by a tightening mechanism, which is self-acting and / or by Energy sources are tightened and / or released. Additionally, the present invention relates to a retensioning mechanism for a surgical working arm. Background technique [0002] Many surgical procedures today use power-operated moveable holding arms that are capable of holding, moving, or controlling specific surgical equipment or instruments. For example, such a movable retaining arm can be transferred from a locked state to a ...
