Surgery

Surgery
Surgery is a medicine that involved cutting into the body to treat a disease or an injury. Surgeons carry out procedure, called operations, in open theatres. An operation may be minor, such as the removal of a skin blemish, or major, such as a heart by-pass operation.
Surgical instrument
These are the instruments used during operations. They include scissors for cutting tissue and trimming stitches, scalpels, used for cutting, refractories, which hold tissue apart, and artery foreceps, used to clamp blood vessels.
Anaesthetics
Anaesthetics are drugs used to relieve a patient’s pain during surgery. The drugs can be injected or inhaled. Local anaesthetic’s numb only the affected part of the body, general anaesthetics render the patient unconscious.
