Abstract
The utility model provides a novel implantable leadless cardiac pacemaker, which comprises a pacemaker body, a connector arranged on one side of the pacemaker body and a mounting disc fixedly arranged on the other side of the pacemaker body and provided with electrodes in the middle, wherein one side of the mounting disc, which is positioned outside the electrodes, is fixedly provided with a limiting mechanism which is positioned outside the pacemaker body and distributed in an annular mode. This novel implantable leadless cardiac pacemaker sets up the support frame through the one end of main holder and can support main holder, and then guarantees to have sufficient effort between main holder and the myocardium to guarantee leadless cardiac pacemaker and be difficult to produce the removal, through the cooperation of main holder, first vice holder and the vice holder of second use, can increase the contact surface between holder and the myocardium, and then reduce the effort on the holder unit area, make the holder be difficult to cause the myocardial perforation.
Description
Technical Field
The utility model relates to the technical field of medical appliances, and particularly discloses a novel implantable leadless cardiac pacemaker.
Background
The cardiac pacemaker is one kind of electronic therapeutic instrument implanted inside body, and has pulse generator to emit electric pulse to stimulate cardiac muscle to excite and contract, so as to treat cardiac dysfunction caused by arrhythmia.
In the using process of the existing part leadless cardiac pacemaker, as the retainer lacks support, the acting force between the retainer and cardiac muscle is small, so that the leadless cardiac pacemaker is easy to move, meanwhile, the contact area between the retainer and the cardiac muscle part is small, the acting force on the unit area of the retainer is large, and the retainer is easy to cause cardiac muscle perforation.
Disclosure of Invention
In view of the above-mentioned defect or deficiency in the prior art, this application aims at providing a novel implantable leadless cardiac pacemaker, including the pacemaker body, set up connector and fixed mounting in pacemaker body opposite side and the middle part is provided with the mounting disc of electrode in pacemaker body one side, one side fixed mounting that the mounting disc is located the electrode outside has the stop gear that is located the pacemaker body outside and be annular distribution.
Preferably, the limiting mechanism comprises a main retainer fixedly mounted on the mounting plate, and a first auxiliary retainer and a second auxiliary retainer are respectively arranged on the outer side of the main retainer.
Preferably, a supporting frame is arranged at one end of the main retainer far away from the mounting plate.
Preferably, the outer side of the pacemaker body is provided with a limit groove matched with the supporting frame.
The beneficial effects are that:
1. this novel implantable leadless cardiac pacemaker sets up the support frame through the one end of main holder and can support main holder, and then guarantees to have sufficient effort between main holder and the myocardium to guarantee leadless cardiac pacemaker is difficult to produce and removes.
2. According to the novel implantable leadless cardiac pacemaker, through the cooperation of the main retainer, the first auxiliary retainer and the second auxiliary retainer, the contact surface between the retainer and cardiac muscle can be increased, and then the acting force on the unit area of the retainer is reduced, so that the retainer is not easy to cause cardiac muscle perforation.
