2 Surgical Instruments:
The following instruments are used during surgery Many of these look very similar and may be hard to distinguish between! We will break these tools down into smaller sub-groups: Forceps: used to pinch or tweeze tissue Scissors: used to cut tissue Scalpel/Needle: used to cut or pierce tissue Surgical miscellaneous

3 Forceps Used to grasp and hold objects
You should be able to identify the following forceps: Alligator Allis tissue Babcock tissue Crile Kelly Halstead mosquito hemostatic Brown-Adson thumb Rat-tooth thumb

4 Alligator Used during surgery to remove foreign bodies
There is a right angle and the top blade is the only part that actually moves

5 Allis tissue Used during surgery to grasp organs and slippery/dense tissue Less delicate than Babcock forceps due to the sharp teeth present at the tip of the blade

6 Babcock tissue Used during surgery to hold delicate tissue
Similar to Allis Tissue forceps but the tips are smooth

7 Crile Used to occlude bleeding before ligation (stops bleeding before closing off a blood vessel) Serrations run the full length of the jaws, can be curved or straight

8 Kelly Used to occlude bleeding before ligation (stops bleeding before closing off a blood vessel) VERY similar to Crile forceps, but serrations only run about halfway up the distal length of the jaw, can be curved or straight

9 Halstead mosquito hemostatic
Used to occlude bleeding before ligation (stops bleeding before closing off a blood vessel) SMALLER than the Crile or Kelly, serrations run the full length of the jaws, can be curved or straight

10 Brown-Adson thumb Used during surgery to grasp and hold tissue, muscle, or skin Fine serrations are present, there are no teeth at the tip

11 Rat-tooth thumb Used during surgery to grasp and hold tissue, muscle, or skin Difference between Brown-Adison and rat tooth is the rat tooth has teeth at the tip of the instrument

12 Scissors Surgical instruments used for cutting material and tissue
You should be able to identify the following scissors: Suture wire cutting Bandage Littauer suture removal Mayo dissecting Metzenbaum dissecting

13 Suture wire cutting Used to cut wire sutures
The blades are serrated, can be curved or straight

14 Bandage Used to remove bandages
There are many types of bandage scissors, but they will all have a longer bottom blade that has a blunt tip (helps to prevent cutting skin)

15 Littauer suture removal
Used to cut all kinds of sutures (but wire) Has a hook-shaped bottom blade Can be curved or straight

16 Mayo dissecting Used during surgery to cut body tissues and sutures
Have blunt ends with a shorter and broader shanks than Metzenbaum, can be curved or straight

17 Metzenbaum dissecting
Used during surgery to cut delicate tissue Longer and more narrow shanks than Mayo scissors Can have curved or straight blades

18 Scalpel/Needle Instruments
You will need to identify the following scalpel/needle instruments: Scalpel blade Scalpel handle Suture needle Cutting Taper Needle holder Mayo-Hegar Olsen-Hegar The needle holders are used during suturing of the patient, a ratchet is present near the finger rings, meaning that they lock in place when closed (this is to prevent the needle from slipping!)

19 Scalpel blade Used in surgery to cut through different tissues
An extremely sharp blade that attaches to a scalpel handle

20 Scalpel handle Used during surgery to hold the scalpel blade, making it easier for the veterinarian to manipulate the blade

21 Suture needle - cutting
Often used during surgery to close skin and subcutaneous tissue Needle point is triangular with a cutting edge

22 Suture needle - taper Often used in surgery to close soft tissue (ex. fascia, gastrointestinal tissue, vascular tissue) No cutting edge on the tip

23 Needle holder (Mayo-Hegar)
Used in surgery to hold the needle while suturing tissue No cutting blades

24 Needle holder (Olsen-Hegar)
Used in surgery to hold the needle while suturing tissue and to cut suture material Similar to Mayo-Hegar but also has cutting blades on the proximal end of the blade

25 Surgical Miscellaneous

32 Sterilization Instruments
The following machines and tools are used to sterilize veterinary instruments for surgery and other procedures You will need to identify the following tools: Autoclave Autoclave tape indicator Chemical indicator strips Cold sterile tray

33 Autoclave This machine is used to sterilize veterinary instruments for surgery and other procedures It used high heat and pressure to sterilize

34 Autoclave tape indicator
This tape is put on surgery packs before being autoclaved If the autoclave works properly, then stripes on the tape turn black (or another color), indicating that the contents of the pack have been properly sterilized

35 Chemical indicator strips
Another way to identify sterilization in surgical packs Strip changes color after sterilization

36 Cold sterile tray Another way to sterilize instruments
No heat is applied, instead chemicals are used

37 Examination/Diagnostic Tools
