ROTATABLE ANTRUM BACKBITING PUNCH BACKWARD CUTTING PTFE COATED

Description

A rotatable antrum backbiting punch is a specialized surgical instrument used in endoscopic sinus surgery, particularly in procedures involving the maxillary sinus. This instrument is designed to facilitate the removal of bone and tissue from the posterior wall of the maxillary sinus to improve access and visibility during the surgery.

Here’s what each term refers to:

1. Rotatable: The term “rotatable” indicates that the instrument has the ability to rotate or swivel around its axis. This feature allows the surgeon to adjust the orientation of the punch to better align with the surgical site and facilitate precise bone removal.
2. Antrum backbiting punch: This refers to the specific design and function of the instrument. An antrum backbiting punch is used to remove bone and tissue from the posterior wall of the maxillary sinus, which is located in the back part of the cheekbone (maxilla). This type of punch is typically designed to reach deep into the sinus cavity to access hard-to-reach areas.
3. Backward cutting: The term “backward cutting” indicates that the cutting edge of the punch is oriented in such a way that it cuts in the direction opposite to the movement of the instrument. This allows the surgeon to efficiently remove bone and tissue while minimizing trauma to surrounding structures.
4. PTFE coated: PTFE stands for polytetrafluoroethylene, which is a synthetic fluoropolymer commonly known by the brand name Teflon. In this context, PTFE coating refers to a non-stick surface treatment applied to the instrument’s cutting edge. This coating reduces friction and prevents tissue or bone from adhering to the punch during the surgery, making it easier to maneuver and improving overall efficiency.
