Description

Operating forceps for cardiac operation

Technical Field

The invention relates to the technical field of heart surgery instruments, in particular to a pair of surgical forceps for heart surgery.

Background

When the heart has pathological changes and other problems, the treatment is needed in time, generally comprises drug treatment, and seriously needs surgical treatment. The operation treatment needs to be performed by opening the chest, and in the chest opening process, an operation clamp is used as an auxiliary appliance.

The patent with the application number of 200720158079.6 provides an operation clamp which mainly comprises clamp heads and clamp handles, wherein the rear ends of the clamp handles are provided with step-by-step occlusion hooks, and the inner side of one clamp head is provided with transverse grains, an arc-shaped transverse groove and a strip-shaped cutting edge from the end part downwards in sequence; the inner side of the other binding clip is provided with two arc-shaped transverse grooves and a saw-toothed blade in turn from the end part downwards, wherein the first groove corresponds to the transverse striation on the first binding clip, the second groove corresponds to the groove on the first binding clip, and the saw-toothed blade corresponds to the strip-shaped blade on the first binding clip.

When the improved surgical forceps are used for fixing and clamping relatively fine tissues, the distance between the operating end of the forceps and a target object is relatively long, and a clamping error is easily generated under the condition of relatively long arm of force due to the lever principle used by the forceps; secondly, the length of the forceps body can not be adjusted by the surgical forceps, so that the surgical forceps are inconvenient to flexibly operate according to conditions in the surgical process; finally, the existing surgical forceps are more in types, each surgical forceps corresponds to one forceps head shape, and if one forceps is multipurpose, the applicability of the surgical forceps is greatly improved.
