Parkinson’s disease can be treated by brain pacemaker surgery. After the surgery, we will also encounter such questions as: how often is it better to recharge the battery after the surgery? If the battery is dead, what should I pay attention to when changing the battery? 1.How often is it better to charge the battery after surgery? “This problem is a problem we often encounter when we recommend rechargeable batteries, this and our regular battery cognition is different, the number of times of charging does not cut the performance of the use, the use of the battery is very smooth, not a slope down.” Prof. Wang said, “One of the recommendations we give to patients on a daily basis is that it is very safe to have a charge of 50% or more, or to go and recharge once a week at a set time, which is fine, and it doesn’t take a long time to fill up.” There is also the possibility of filling it up when you think of it, depending on the patient’s habits, and this also doesn’t take a lot of time. It can also be timed according to the habits of the family and the combination of staff, as many patients need to be reminded and cared for. As long as to ensure that the power is not very low, these charging methods are possible. 2.What do I need to pay attention to when changing batteries? “Because changing batteries is a problem that will occur in the past when fixed power equipment is used for many years, it is not recommended to change it after a complete power failure, because after the power failure, the original symptoms may appear, and if you still want to achieve the preoperative effect, you may need a buffer time, otherwise the patient will be very difficult. It is recommended to go with the programmer in time to see how long the power will last and to replace it before the power is cut off. It will be simpler and the integrity of the circuit will be safer and more certain before the surgery. Changing the batteries won’t be too much of a problem, the main thing is to reopen the wound and implant a new one of this machine, which is more demanding in terms of infection control.”
