Problems solved by technology

[0002] At present, in the treatment that requires thoracotomy, the operation of the sternal closure fixer used in the chest closure operation is still not ideal, and the second thoracotomy cannot be performed immediately on any occasion without special equipment. After being used in the hospital, when the patient has arrived in the ICU of the ward, the thoracotomy is required immediately due to a sudden illness. If the patient is moved to the operating room, the time is not allowed, and the thoracotomy must be taken immediately for rescue. The opened instruments are in the operating room, and they have not even been sterilized. If there is a claw-shaped sternum fixer that can be opened without any tools, it will win valuable time for rescuing patients.
Cardiac surgery is generally carried out in large specialized hospitals with high technical level. When the patient is discharged from the hospital and returns to the local area, if there is an emergency, it is too late to go to the original hospital for treatment.
