Retractors play a crucial role in providing visibility and access during surgery, making them indispensable in the operating room.
Sutures and Needles
Types of Sutures
Sutures are threads used to close wounds. They come in two main types:
- Absorbable Sutures: These dissolve in the body over time. They are used for internal tissues.
- Non-Absorbable Sutures: These need to be removed by a doctor. They are used for skin and other external tissues.
Needle Varieties
Surgical needles come in different shapes and sizes. Here are some common types:
- Cutting Needles: These have sharp edges and are used for tough tissues like skin.
- Tapered Needles: These have a smooth point and are used for soft tissues inside the body.
- Blunt Needles: These are used for very delicate tissues to avoid damage.
Suturing Techniques
There are several ways to stitch a wound. Some common techniques include:
- Simple Interrupted Stitch: Each stitch is tied off separately. This is the most common method.
- Continuous Stitch: One long thread is used for the entire wound. This is faster but can come undone more easily.
- Mattress Stitch: This method provides extra strength and is used for deep wounds.
Proper suturing is crucial for wound healing and preventing infection. Always follow medical guidelines when performing sutures.
