Study Notes
Grasping and Holding/Suturing Instruments
- Mayo-Hegar Needle Holder is a versatile surgical tool used for both human and animal procedures.
- It is used for intermediate to heavy weight needles while suturing.
- Shorter lengths are used in oral, gynecological, or dermatological procedures.
- Longer lengths are used for deep tissue suturing or in large animal procedures.
Cutting and Dissecting Instruments
- Suture scissors (also known as stitch scissors) are used for small suture removal.
- They have a small hook-shaped tip on one blade that slides under sutures to slightly lift them before cutting.
- They are available in varying lengths, with straight, smooth blunt/blunt tips.
- Dissecting scissors are used for dissecting and cutting tissue only.
- They are lighter and more delicate than standard instruments, allowing for precision with minimal fatigue.
- Surgical scissors are used for general, multipurpose cutting and dissecting.
- They are available in multiple lengths, with three tip configurations – sharp/sharp, blunt/blunt, and sharp/blunt.
Grasping and Holding Instruments
- Allis forceps are used to lift, hold, and retract slippery or dense tissue.
- They are commonly used with tonsil, vaginal, breast, and thyroid tissue.
- They are available in a variety of lengths, with narrow tips and atraumatic teeth.
- Foerster-Ballenger Sponge Forceps are used to hold gauze that absorbs excess fluids and blood from a surgical site.
- They are often used in bariatric surgeries because of their longer length.
- The curved version may be used for removing the placenta in OB/GYN procedures.
Additional Cutting and Dissecting Instruments
- Tissue scissors (also known as Metz, dissecting scissors, or delicate scissors) are used for dissecting and cutting delicate tissue.
- They are longer, thinner scissors with a relatively long shank to blade ratio.
- They may have straight or curved blades, and blunt tips.
