Closure device for tissue suturing

Abstract

The invention discloses a closing device for tissue suturing, the closing device is provided with a far end and a near end which are opposite, the closing device comprises a handle, the handle is provided with a first driving mechanism, and the first driving mechanism comprises a driving part and a driven part which are in threaded fit; the near end of the catheter is fixed on the handle; and the two operating arms are rotationally connected to the far end of the catheter, each operating arm is provided with a needle holding mechanism, and each operating arm is controlled by the corresponding driven piece through a traction piece, so that each needle holding mechanism interacts with the tissue and is used for threading a suture needle of a suture. According to the closing device, more tissue closing scene requirements can be met by improving the movement modes of the two operation arms, and in addition, the operation synchronism and the structure simplification are guaranteed by aiming at the arrangement of the driving mechanism.
