What is a carpule?

• A. A type of surgical instrument for cutting
• B. A cartridge containing liquid medication for injection
• C. A container for holding surgical supplies
• D. A device for suturing wounds

Answer: (B)

A carpule is specifically defined as a cartridge that contains liquid medication intended for injection. This term is commonly used in dental and medical contexts, particularly when discussing local anesthesia delivery systems. When the carpule is fitted into a syringe, the medication can be drawn and administered efficiently and accurately.

This function is critical in procedures requiring localized pain management since it allows for precise dosages of anesthetics to be applied at the site of treatment. Understanding the role of the carpule is essential for anyone involved in surgical settings, as it directly impacts patient comfort and the effectiveness of various procedures.

The other options relate to different types of instruments and devices used in surgery, but they do not accurately describe what a carpule is or its specific purpose in medical practice.
