Arthroscopic Accessory Surgical Instrument-Puncture Device

Introduction to Arthroscopic Accessory Surgical Instrument-Puncture Device
In the context of arthroscopic surgery, the puncture device is a fundamental and crucial instrument.
It typically consists of a sharp, hollow needle-like structure attached to a handle. The design of the needle is highly refined, with a fine tip that allows for precise penetration through the skin and soft tissues, minimizing trauma. The hollow core serves the essential function of creating a passageway for the introduction of arthroscopic instruments, such as the arthroscope itself or other ancillary tools like probes and forceps.
The diameter of the puncture device is carefully calibrated. For example, a commonly used size might be in the range of 4-10mm, depending on the specific requirements of the surgery and the joint being operated on. A smaller diameter reduces the initial puncture wound but may limit the size of instruments that can be inserted subsequently, while a larger diameter provides easier access for bulkier tools but demands more caution during insertion to avoid excessive tissue damage.
During a knee arthroscopic procedure, the surgeon first locates the appropriate entry point. Then, using the puncture device, they carefully insert it through the skin, fascia, and into the joint cavity. Once inserted, the stylet (if present) is removed, leaving the hollow channel. Through this channel, the arthroscope can be inserted to provide a visual inspection of the joint interior. Subsequently, other necessary instruments can also be passed in and out as the surgery progresses, all facilitated by the initial puncture made by this device.
Overall, the arthroscopic puncture device is the gateway for the entire arthroscopic surgical process, enabling surgeons to access the joint space in a minimally invasive manner and laying the foundation for successful joint interventions.
