What are the parts of a surgical needle. How do you classify surgical needles
The surgical needle is comprised of 3 parts: the needle point, the needle body, and the swaged (press-fit) end.
Needle may be broadly classified as
- Traumatic
- Atraumatic
1. Traumatic needles are needles with holes or eyes which are supplied to the hospital separate from their suture thread. The suture must be threaded on site, as is done when sewing at home.58 Practical Manual

- straight
- half curved or ski
