Surgery 6th year, Tutorial (Dr. AbdulWahid)Presentation Transcript
HISTORY The origins of surgery can be traced back many centuries. Through the ages, practitioners have used a wide range of materials and techniques for closing tissue…….. 1650 BC – 2000’s AD
In the tenth century BC, the ant was held over the wound until it seized the wound edges in its jaws. It was then decapitated and the ant's death grip kept the wound closed. Ants
Thorns The thorn, used by African tribes to close tissue, was passed through the skin on either side of the wound. A strip of vegetable fibre was then wound around the edge in a figure eight.
Sterilised Catgut The tough membrane of sheep intestine was provided to the surgeon pre-sterilised and required threading through the eye of the needle before use.
Swaged On Needles Post World War II brought the swaged-on needle. The thread fits into the hollow end of the needle, allowing it to pass through tissue without the double loop of thread that exists with a conventional needle, reducing tissue trauma.
