Vena cava separating forceps used for cardiac minimally invasive surgery

Abstract

The invention relates to operative instruments and particularly to a vena cava separating forceps used for a cardiac minimally invasive surgery. The vena cava separating forceps used for a cardiac minimally invasive surgery comprises a fixed big body, a movable big body, a fixed forceps head, a movable forceps head and two finger ring type handles, wherein the fixed big body and the movable big body are bent upwards for 30 degrees, and the fixed forceps head and the movable forceps head are bent downwards. A locking buckle is arranged at the inner side of each of the two finger ring type handles, and De Bakey teeth are arranged at the inner sides of both the fixed forceps head and the movable forceps head. The vena cava separating forceps is placed in from an operative incision; the double-joint design enables a cutting forceps to be opened and closed conveniently and come in and go out of an operative hole freely without being affected by the thickness of the chest wall and the depth of the chest cavity; the forceps is prevented from damaging surrounding tissues. The bending design of the forceps body brings convenience for the cutting forceps handle to be tightly attached on the chest wall and meets with operating behaviors of doctors and ergonomic principles. The structure of the tooth part of the forceps head is good for preventing blood vessels from sliding; a clamping tooth structure enables the adjustment of the clamping force of the forceps to be more flexible.

Description

(1) Technical field [0001] The invention relates to a surgical instrument, in particular to a vena cava separating forceps used for minimally invasive heart surgery. (2) Background technology [0002] At present, in cardiac surgery, after the establishment of extracorporeal circulation, the superior and inferior vena cava should be separated from the surrounding tissues to facilitate cuff occlusion, and the vena cava separating forceps should be used. However, in minimally invasive surgery, the surgical incision is small and the vena cava is located deep. The vena cava separation forceps currently used in clinical practice are short in length and straight in shape with fixed heads. It is difficult to fully free the posterior wall of the vena cava. , so it must be improved. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a vena cava separating forceps for minimally invasive cardiac surgery,...
