Technical Field

The invention relates to the technical field of medical instruments, in particular to a valve spreader with a suction device.

Background

With the development of cardiac surgery and extracorporeal circulation techniques, more and more patients are subjected to minimally invasive cardiac surgery. The operation of reducing the incision and causing slight trauma has high requirements on the operation skill, and the operation field needs to be kept free from blood interference and clear and distinguishable. Especially, in the endoscopic mitral valve operation, the exposure under the valve is difficult, the operative field is not exposed clearly only by the left atrial retractor, the needle position of the suture valve line is not ideal, the valve leakage after opening is caused, the replaced valve needs to be detached again, and the good exposure in the operation has important significance for successful valve replacement or forming.

In addition, the mitral valvuloplasty operation can improve the later life level of patients without the need of lifetime warfarin anticoagulation treatment, so that the mitral valvuloplasty operation is the first treatment method for treating the mitral valvulomalacia lesion caused by chordae rupture at present. Minimally invasive mitral valvuloplasty under thoracoscopy is widely accepted by people because of small wound, small incision, no need of splitting sternum longitudinally, few postoperative complications and quick recovery. However, the minimally invasive mitral valvuloplasty is a high-precision surgery, especially a surgery involving artificial chordae tendineae reconstruction, and the artificial chordae tendineae reconstruction-type mitral valvuloplasty needs to be subjected to examination of the artificial chordae tendineae for up to 10 ten thousand heart beats per day, and has a particularly high requirement on exposure of the surgical field; however, the incision is small and the exposure is poor, so that the operation is inconvenient, the needle inserting point of the surgical suture needle on the chordae tendineae is influenced, and the curative effect of the surgery is finally influenced.

Disclosure of Invention

The technical problem to be solved by the present invention is to provide a valve spreader with a suction device, which can make the operation view wide and clear and is convenient for the doctor to operate in the surgical operation, aiming at the defects of the prior art.

The invention aims to provide a valve spreader with a suction device, which comprises a spreader body, wherein the spreader body mainly comprises a support rod, a C-shaped plastic elastic sheet and a suction head, the suction head is fixedly arranged on the C-shaped plastic elastic sheet, one end of the suction head, which is far away from the C-shaped plastic elastic sheet, is uniformly provided with a plurality of side holes, the middle position of the outer side of the C-shaped plastic elastic sheet is vertically provided with a tubular connecting port, the support rod is a hollow bendable hose, one end of the support rod is inserted into the tubular connecting port of the C-shaped plastic elastic sheet and is detachably connected with the C-shaped plastic elastic sheet, the other end of the support rod is integrally provided with a connecting circular tube, the diameter of the connecting circular tube is larger than that of the support rod, and the side wall of the connecting circular tube is provided with a porous luer cap through a luer connector.

Furthermore, the edges of the side edges of the C-shaped plastic elastic sheet are rounded corners, the width of the C-shaped plastic elastic sheet is 100mm-150mm, and the spreading range of the C-shaped plastic elastic sheet is 19mm-33 mm.

Further, attract the fixed tubular connector department that sets up in the C shape plastic shrapnel outside of head, attract the length of head to be 50mm, attract the head to evenly be provided with a plurality of side openings in the 20mm of the near tail end.

Furthermore, the support rod and the connecting circular tube are both medical plastic hoses, the outer diameter of the support rod is 1/16-1/8 inches, and the outer diameter of the connecting circular tube is 1/4 inches.

Further, the C-shaped plastic elastic sheet is made of medical polyethylene material.

Further, the suction head is made of a medical silica gel material.

The invention has the beneficial technical effects that: the valve spreader with the suction device can spread the valve and simultaneously suck the blood in the left ventricle by being connected with the external negative pressure suction device, so that the operation visual field is wide and clear, and the operation of doctors in the surgical operation is convenient.
