The invention discloses an auxiliary instrument for treating calcified cardiac valves based on balloon valvuloplasty. The auxiliary instrument comprises a bottom plate, wherein supporting rods are arranged at the four corners of the upper portion of the bottom plate, a supporting frame plate is arranged at the top parts of the supporting rods, side plates are symmetrically arranged on the two sides of the upper surface of the supporting frame plate, grooves are formed in the upper surfaces of the side plates, a first movable plate is embedded in one end of the interior of each groove, a second movable plate is embedded in the other end of the interior of each groove, sliding grooves are symmetrically formed in the two sides of each groove, and a first sliding rod penetrates through the bottom part of each first movable plate and penetrates through the interiors of the corresponding sliding grooves. Through the arrangement of the first movable plates, the second movable plates, cross rods, connecting rods, threaded holes, lead screws, the two connecting sleeves and other structures, the height of the cross rods can be adjusted, cloth possibly used in the operation process can be conveniently unfolded and laid on the cross rods, hemostatic cloth can be conveniently transferred to a doctor in the operation process, the situation that the hemostatic cloth cannot be supplied in time in emergency of the operation is avoided, and the operation can be smoothly carried out.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for treating calcified heart valves based on balloon valvuloplasty. Background technique [0002] Senile calcific valvular heart disease is a heart valve disease unique to the elderly, which is mainly characterized by degeneration, thickening, fibrosis and calcification of the valve connective tissue, which in turn leads to abnormal function of the valve and its stent. This disease is usually caused by degenerative changes in the connective tissue of the heart valve. After the disease, the patient's body will be greatly affected, and it is necessary to pay attention to it in time and take countermeasures. There are three main types of treatment available: (1) Internal medicine can be used for heart valve calcification; (2) Traditional Chinese medicine treatment can also be used for heart valve calcification; (3) If the heart valve calcification is seri...
