Description

Calcification focus remove device Technical Field The specification relates to the technical field of medical equipment, in particular to a calcification focus removing device. Background Calcification of heart valves is a degenerative change of heart with age, and has close relation with age, hypertension, diabetes, hyperlipidemia, calcium-phosphorus metabolic disorder and other factors. Heart valve calcification is primarily aortic valve calcification, and secondarily mitral valve calcification, tricuspid valve or pulmonary valve calcification being relatively rare. This may be associated with higher mechanical stress experienced by the left heart system valve, with relatively greater changes in the impact and shear forces experienced by the aortic valve, and also more likely to result in damage to the valve surface, fracture of collagen fibers, and subsequent chronic inflammatory reactions and deposition of calcium salts. Calcified valves may undergo functional changes, most of which are under-closing, and a small portion of which may also exhibit valvular stenosis, etc. If calcification of the heart valve causes problems with the functioning of the valve itself, such as regurgitation due to insufficient closure of the valve or poor blood flow due to stenosis of the valve, corresponding surgical procedures are required, which may typically include heart valve replacement surgery or minimally invasive calcification removal surgery. To this end, the present description provides a device for removing calcified lesions. The calcification focus removing device provided in the specification can be used for removing calcification focuses on heart valves and also can be used for removing calcification focuses on other parts (such as blood vessel walls). Disclosure of Invention Some embodiments of the present disclosure provide a calcified lesion removal device comprising a support rod and a vibration head, the support rod and the vibration head being connected, the support rod being capable of controlling the vibration head to retract in a delivery tube and the vibration head to extend from the front end of the delivery tube and to expand, the vibration head being capable of generating vibrations. In some embodiments, the vibration head comprises a folder and a bag body, wherein the folder comprises at least two folding wings, the bag body is arranged on the surfaces of the folding wings, the folding wings can drive the bag body to fold or unfold, and the bag body can generate vibration. In some embodiments, the interior of the capsule is capable of containing a gas and/or a liquid, and the interior of the capsule is provided with at least one pair of electrodes capable of acting on the gas and/or the liquid inside the capsule to generate a shock wave. In some embodiments, the calcification focus removing device further comprises a fluid tube in communication with the balloon through which gas and/or liquid can be injected into or exhausted from the balloon to effect inflation or deflation of the balloon. In some embodiments, the surface of the bladder is provided with a plurality of teeth. In some embodiments, the plurality of convex teeth form one or more toothed rings, and the region surrounded by the toothed rings is provided with a piston cylinder capable of being recessed into the interior of the bladder when the bladder is contracted. In some embodiments, the piston cylinder is an integrally formed structure with the bladder, the wall thickness of the piston cylinder being less than the wall thickness of the bladder. In some embodiments, the bag body comprises a first bag body and a second bag body which are oppositely arranged, the folder comprises a first folding wing and a second folding wing which are oppositely arranged, the first bag body is arranged on the inner surface of the first folding wing, the second bag body is arranged on the inner surface of the second folding wing, when the first folding wing and the second folding wing are folded, the first bag body and the second bag body are mutually attached, one or more tooth rings are arranged on the first bag body and the second bag body, and the positions of the tooth rings on the first bag body correspond to the positions of the tooth rings on the second bag body. In some embodiments, the support rod is rotatably connected with the folding wing, the folding wing is made of an elastic material and is in an unfolding state in a natural state, or the support rod is connected with the folding wing through an opening and closing control mechanism, and the opening and closing control mechanism is used for controlling the folding wing to fold or unfold. In some embodiments, the calcified lesion removal device further comprises a conveying pipe, wherein a hemostatic valve sheet is arranged at the middle or rear end of the conveying pipe, the hemostatic valve sheet is made of flexible materials, and the hemostatic valve sheet comprises a cross-shaped gap
