Problems solved by technology

In this context, however, it has been found that surgical instruments with complex mechanical interiors appear less suitable as "single-use instruments" because the advantages of using low-priced plastic materials are outweighed by the high installation costs in complex instruments. need

Embodiment Construction

[0043] From figure 1 , Figure 2a and Figure 2b , shows in a pictogram-like manner a manually actuatable surgical instrument according to a preferred embodiment of the present invention, and illustrates two variants for an optionally used shaft tool, namely, a bone punch and a bite Bone pliers tool. It has already been outlined in this context that other shaft tools can also be chosen, such as pliers, scissors or tweezers.

[0044] The surgical instrument according to the invention thus has a modular structure (in particular according to the modular principle) and comprises an instrument grip, preferably a pistol grip 1, which forms a receiving housing, in particular for the actuating lever 2 , the actuating lever 2 is articulated in the pistol grip 1 in the manner of a rocker to an engagement point 8 on the handle side. The first actuating part 2 a of the rocker-type actuating lever 2 protrudes from the pistol grip 1 , and thus from the receiving housing, and serves as a...

Abstract

The invention relates to a disposable surgical instrument which, in accordance with the principle of a modular system, has the following elements: an instrument grip, preferably a pistol grip, which forms a receiving housing, in which instrument grip a separate handle such as an actuating lever is mounted in the manner of a rocker on an articulation point on the handle side; and a shaft-mounted tool, consisting of a shaft comprising at least two relatively axially movable bar or rod components and an instrument head having patient engagement elements which can be actuated by the two relatively axially movable bar or rod components, of which a bar or rod component is fixed at the proximal end thereof to the instrument handle and the other, movable bar or rod component has on the shaft side an articulation point on which the handle is directly articulated in such a way that a manually actuated rocker movement of the handle about the articulation point on the handle side is transformed directly into an axial movement of the other bar or rod component on the articulation point on the shaft side.

Description

technical field [0001] The invention relates to a surgical manual instrument which has a modular design and can therefore be equipped with different surgical tools according to the principle of a modular system. The concept is particularly suitable for being designed as a disposable device. Background technique [0002] Surgical medicine offers numerous applications of so-called "single-use instruments", which, due to their single use, do not need to undergo any complicated decontamination and / or sterilization processes and whose handling is therefore less burdensome for the patient. Simple and safe. Crucial to the profitability of this type of "single-use device" are minimal manufacturing costs and adequate functionality that should not be ranked behind conventional reusable devices. [0003] current technical level [0004] Disposable surgical instruments are known in the state of the art. Disposable surgical instruments generally consist of several basic elements made...
