An LED chip package structure includes a conductive unit, a first package unit, an ESD unit, a second package unit, a light-emitting unit and a second package unit. The conductive unit has two conductive pins adjacent to each other which form a concave space between each other. The first package unit encloses one part of each conductive pin in order to form a receiving space communicating with the concave space and to expose an end side of each conductive pin. The ESD unit is received in the concave space and electrically connected between the two conductive pins. The second package unit is received in the concave space in order to cover the ESD unit. The light-emitting unit is received in the receiving space and electrically connected between the two conductive pins. The third package unit is received in the receiving space in order to cover the light-emitting unit.

An automatic bone drilling apparatus for surgery operation uses a computer to control a hand tool drilling device to drill opening in skeleton. The computer has a fuzzy logic software to control the hand tool operation through a control box and a manual-automatic mode switch box. The hand tool drilling device may be securely mounted on the patient. Drilling location and size and depth may be precisely controlled to enhance surgical operation safety. It is particularly useful for drilling patient skeleton for brain surgery operation.
