**VS105 Handout \#1** **Unit \#1- SURGICAL INSTRUMENTS:** **DESIGN AND FUNCTION Part 1** **Objectives:** 1\. Identify the various parts of an instrument 2\. Explain the 3 different serrations of instruments 3\. Demonstrate the proper hold for various instruments **The parts of an instrument:** 1. **[\_\_\_\_\_\_\_\_\_\_]:** - **Some instruments have teeth on their ends, which help to \_\_\_\_\_\_\_\_\_\_ tissue and ensure a \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** 2. **\_\_\_\_\_\_\_\_\_\_:** - **The jaws refers to the part of the instrument which "open and close".** - **Usually used for cutting or crushing tissue**  3. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_:** - **Some instruments have a \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ which allows the instrument to be locked in a closed position.** - **The box lock absorbs a lot of \_\_\_\_\_, and should be checked frequently** 4. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_:** - **This is part of the box lock hinge mechanism consisting of interlocking teeth which locks the jaws in a closed position** 5. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_**: - This is the body of the instrument and is usually the longest area. - The shank determines the instrument's overall length which may range from 3-12 inches in total length depending on the length of the shank. 6. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_:** - **Finger holes for holding the instrument -- most instruments are held with the thumb and ring finger in each hole.** Image:101424000-Haemostat-ratchet.jpg  7. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_:** - **The jaws of instruments used to crush or hold tissue will have serrations or lines grooved into the instruments jaws.** **These serrations may be:** i. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ (vertical) -- which means they run the length of the jaw** ii. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ (horizontal)- they run across the jaws** iii. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ where the grooves form a checkerboard or cross hatched pattern**  **[Variations of Instruments: ]**  http://coursewareobjects.elsevier.com/objects/elr/Sonsthagen/instruments2e/IC/images/014u011.jpg **How to Properly Hold an Instrument:** - **Depends on the instrument you are holding** - **Hemostatic forcep vs Thumb forcep vs Scalpel handle** 1. **For hemostats and \_\_\_\_\_\_\_\_\_\_\_\_** - **Finger rings: \_\_\_\_\_\_\_\_\_\_\_and 3rd finger** - **Middle finger supporting the\_\_\_\_\_\_\_\_ of the instrument** - **Pointer finger will guide the instrument** - **Pinky finger for support**  2. **Thumb forceps:** - **"\_\_\_\_\_\_\_\_\_\_\_" hold** - **Held between the \_\_\_\_\_\_\_ and the first finger in the non-dominant hand** - **Rests on the remaining fingers** thumb forceps holding correct 3. **Scalpel Handle** - **Held between the thumb and middle finger** - **Pointer finger used for guiding** - **Non-dominant hand**
