T7: Instrumentation and Care Flashcards
a basic surgical kit will comprise the following instruments:
- scalpel handle
- towel clamps
- scissors - one for muscle/soft tissue and one for sutures
- forceps - plain or ‘dressing’ for holding delicate tissue, “rat-toothed” for holding skin and soft tissue without slipping
- haemostats or artery forceps
- allis tissue forceps or peritoneal forceps - used to maintain a locked grip on the peritoneum (lining of abdominal cavity) to lift the body wall and gain access to the internal organs
- needle holders - Mathieu needle holders which have a ratchet for maintaining grip; Gillies needle holders which incorporate scissors for cutting suture material; Olsen-Hegar needle holders have a ratchet and scissors; Mayo-Hegar needle holders have a ratchet but no scissors
- spey hook
How should scalpel blades be attached to and removed from a scalpel handle?
should only be attached to and removed from the scalpel handle using needle holders (never use haemostats) or an instrument which is designed only for holding metal as opposed to being used on living tissue
What instrument is this?
backhaus towel clamp
What instrument is this?
Jones towel clamp
What shapes or types may scissors be?
points are described variously as sharp/sharp, blunt/blunt or sharp/blunt and they can be curved, straight or modified for special uses

Metzenbaum scissors
used for delicate tissue and come in different sizes. These should never be used for cutting bandages!
What kind of scissor is this?
nursing/bandage scissors
What are forceps used for?
(tissue/rat-toothed)
- holding tissues during dissection
- closure procedures
What are plain forceps used for?
holding tissues where a more delicate grip is required
What instrument is this and what is it used for?
- Haemostats
- used for clamping, holding or crushing tissues.
- commonly used for clamping off bleeding vessels, tissue stumps etc.
- The ratchet enables the instrument to be locked into position for maintaining a grip until released by spreading the finger grips.
What instrument is this and what is it used for?
- Allis clamps or peritoneal forceps
- for maintaining a locked grip on tissues, especially the peritoneum
What instrument is this and what is it used for?
- spey hook
- allows the ovary, fallopian tube or uterine horn to be snared.
higher the number, the …… the needle.
smaller

- an eye
What are round bodied needles used for?
internal, soft tissue
What are cutting needles used for?
skin sutures (because of the cutting edge, they can damage soft tissue)
What instrument is this?
- Mathieu needle holders
- These incorporate a ratchet for maintaining a grip without muscle strain and a quick release by squeezing.
What instrument is this?
- Gillies needle holders
- This does not have a ratchet but incorporates a scissor blade for cutting sutures.
What instrument is this?
- Olsen Hegar needle holders
- Combination needle holder and scissors
What instrument is this and what is it commonly used for?
- deep Gelpi retractor
- Most commonly used in orthopedic and spine surgery.
What instrument is this and what is it commonly used for?
