Abstract

The invention provides an implantable medical device. The implantable medical device mainly comprises a mandrel, a locking structure and a clamping structure, a main base and an auxiliary base of the locking structure can be coaxially connected through the mandrel and can be switched between a locking state and a non-locking state, when the locking structure is in the non-locking state, the locking structure can be used for adjusting the clamping distance and the clamping angle of the clamping structure, and when the locking structure is in the locking state, the clamping structure can form the shortest clamping distance and the minimum clamping angle. Therefore, the implantable medical device can provide stable and reliable clamping force, and can be suitable for clamping target tissues with different thicknesses.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, in particular to an implantable medical device. Background technique [0002] Mitral valve, tricuspid valve, aortic valve, pulmonary valve and other common diseases are valvular insufficiency. Current treatment options include aggressive surgical approaches. Commonly used thoracotomy is highly invasive and requires establishment of extracorporeal circulation, which has a high incidence of complications and risk of infection. Patients need to bear huge intraoperative and postoperative risks, as well as huge mental and economic pressure. There are already some implantable devices, but most of them need to change the structure of the heart during the healing process, which brings great pressure and incompatibility to the heart surgery. Such as Figure 29 As shown in an existing instrument, a torsion spring is used to drive the clamping arm to clamp the target t...
