Abstract

The invention discloses a heart tip closing device. The heart tip closing device comprises a puncture part, a positioning part and a catching part, wherein the puncture part is provided with multiplehollow puncture needles, the positioning part is provided with fixing holes corresponding to the puncture needles in number and used for penetrating and fixing the puncture needles, the positioning part is also provided with a through hole for making the catching part to penetrate through, the catching part is provided with loop structures corresponding to the puncture needles in number, and the loop structures can be transformed between a first compressible form and a second dilated form. The heart tip closing device can help doctors to conveniently and quickly close the heart during hybridization operation, and the problem is avoided that the operation performed by a doctor is not convenient due to small exposure area.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an apex closure device. Background technique [0002] Cardiac surgery was the standard operation before the invention of minimally invasive catheter surgery, and it still occupies a high position in the medical field. However, surgical operations have disadvantages such as large trauma, need for extracorporeal circulation, high pain, slow recovery, and high risk. Patients cannot receive effective treatment because they cannot tolerate surgery or are afraid of surgery. The complete minimally invasive catheter operation is a surgical method that enters the heart through peripheral blood vessels to treat diseases. This method only needs to puncture a sheath tube about 1 meter long at the patient's femoral artery or femoral vein to reach the heart, and the operation path is relatively short. Long, and if the patient's peripheral blood vessels themselves have diseases, this method cann...
