Embodiment 1

[0055] This embodiment provides an intracardiac energy harvesting device 100. The intracardiac energy harvesting device 100 has a size and shape suitable for being implanted into a cardiac cavity through interventional surgery. The intracardiac energy harvesting device 100 is applied to into the heart cavity to collect the biomechanical energy generated by the beating heart. Interventional surgery refers to interventional surgery in medicine. It is a minimally invasive treatment using modern scientific and technological means. Under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments can be introduced into the human body to treat diseases in the body. For diagnosis and local treatment. For example, the intracardiac energy harvesting device 100 can be implanted into the heart chamber through a catheter through femoral vein puncture.

Abstract

The invention discloses an intracardiac energy collection device and an implantable electronic medical device, and belongs to the field of medical instruments. The intracardiac energy collection device includes: a shell; a fixing mechanism that is arranged on the shell, and the fixing mechanism is configured to fix the outer shell in the heart cavity so that the shell can move along with beating of the heart; the nano-generator module that is packaged in the shell, and the nano-generator module is configured to output electric energy in response to movement of the shell along with heartbeat; and the power supply management module that is packaged in the shell, and the power supply management module is used for managing the electric energy output by the nano-generator module. The intracardiac energy collection device disclosed by the invention can be implanted into the heart in a minimally invasive intervention operation mode to collect biological mechanical energy generated by cardiacbeat, is small in operation wound, cannot damage the heart, and can effectively avoid infection.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intracardiac energy harvesting device and an implanted electronic medical device. Background technique [0002] With the continuous development of medical technology, there are more and more miniature implantable electronic medical devices that can meet the diagnosis and detection of various diseases. Implantable pulse generators such as cardiac pacemakers and brain pacemakers are widely used in medical diagnosis and treatment. However, almost all implantable medical devices are powered by energy storage media such as batteries. Lithium batteries, as the most mature power supply, have been applied in clinical practice, but they still have an unavoidable shortcoming - limited battery capacity. As a result, the working life of implanted electronic medical devices is affected. When the power of the storage medium decreases or is exhausted, the implanted medical devices cannot work...
