What are the tools they used for organ donation

Organ transplantation is a surgical procedure which involves the transfer of organ from donor to receiver.

Explanation:

The organ transplantation require various medical tools:

Cutting and dissecting instruments:  Scalpels, and scissors to cut the organ from its site of origin.

Holding instruments:  Forceps and clamps are used to handle the organs while cutting them from their original site and placing them in another location.

Homeostatic instruments: Artery forceps to stop the cessation of blood from blood capillaries when an organ is cutted from its place.
