Problems solved by technology

Depending on the tissue resistance at a particular point and the clamping pressure applied, due to insufficient stability of the holding pins of the clamp, the clamping bars move away from each other in a V-shape and can thus result in partial or complete loss of function of the clamp. Excluded

Embodiment Construction

[0070] Such as figure 1 , Figure 1a , Figure 1b As shown, the clamp according to the invention consists of a first clamping bar 1 and a second clamping bar 2, which correspond to each other, the clamping surfaces of which are configured as concave and, if necessary, also have rough, corrugated or uneven surfaces. The clamping bars 1 , 2 can also have clamping surfaces which are configured as flat. The shoulders 6 and 7 are provided at the base of the clamping bars 1, 2, made of a known type of absorbable material; , 2 are guided laterally by means of these shoulders into matching slots 13, 22 of the cassette 11 for their application.

[0071] Essential to the invention is the handle 5 provided at the base of the second clamping bar 2 , which preferably fills the width of the base 12 of the cassette 11 . The first clamping rod 1 with the retaining pin 4 is positioned at the distal end of the cassette 11 (not shown) by pressure clamping. In order to clamp the tissue, the...

Abstract

The present invention provides a surgical clip for minimally invasive surgery and a device for clamping organ tissue, which includes: a first clamping bar corresponding to a second clamping bar, wherein the first clamping bar and the second clamping bar Each is provided with shoulders on both sides of the base for introduction into the cassette, one clamping bar has a continuous holding hole, and the holding pin provided on the other clamping bar is connected therein by press fit and form fit for clamping the organ tissue , the first clamping rod (1) is installed in the box (11) by clamping pressure, the second clamping rod (2) with a continuous holding hole (3) has a handle (5) at its lower end, which is in contact with the During the connection of the first clamping bars (1) together, under the shorter first clamping bar with the retaining pins (4), the organ tissue is clamped by form-fit sliding, or with the retaining pins (4) ) has a shank (5) at its lower end, which, during the process of being connected with the second clamping bar (2), has a shorter holding hole (3) Underneath the second clamping rod (2), the organ tissue is clamped by form-fitting sliding, and thus the tissue forceps has significant additional stability.

Description

technical field [0001] The present invention relates to a surgical clamp for clamping and obstructing soft tissue and blood vessels as an increasing demand in endoscopic surgery in minimally invasive surgery, and to a device for applying the clamp. Background technique [0002] Known surgical clamps are mainly U-shaped or V-shaped, with two clamping bars facing each other, and have a special shape profile. They are brought into the desired clamped and closed position by press-fitting by means of an operating tool suitable for the purpose, called an applicator. Subsequently, a jig made of titanium remains in the body. They can also be made from absorbable plastics such as polypeptides, which are broken down by enzymes in the body. [0003] German application No. 20 2005 009 061 U1 describes a clamp for closing blood vessels. The basic body bears against the open blood vessel with its inner side and closes the blood vessel by a plurality of protruding legs which are flexibl...
