Alcon 8065149527 Microsurgical Instrument 23 Ga Soft Tip Cannula 0.8mm ID


The Alcon 8065149527 Microsurgical Instrument is a 23 Gauge Soft Tip Cannula with a 0.8mm ID (Inner Diameter).
Here's a detailed explanation:
Key Features and Specifications:
Manufacturer: Alcon
MPN (Manufacturer Part Number): 8065149527
Gauge: 23 Gauge (23 Ga). This indicates the outer diameter of the cannula. In medical instruments, a higher gauge number means a smaller diameter. A 23-gauge instrument is considered part of the "small gauge" vitrectomy systems.
Type: Soft Tip Cannula. The "soft tip" is a critical design element, usually made of silicone, which is flexible and atraumatic. This prevents damage to delicate intraocular tissues.
ID (Inner Diameter): 0.8mm. This specifies the size of the lumen through which fluids or materials can be aspirated or infused.
DSP: This acronym likely refers to "Disposable" and "Sterile Pack" or similar, indicating it's a single-use, sterile product.
Usage: Disposable, Single Use.
Packaging: Typically sold in boxes of 10 units.
Sterile: Yes, it's a sterile medical device.
Common Uses in Microsurgery (Primarily Ophthalmic Vitreoretinal Surgery):
The 23-gauge soft tip cannula is a fundamental tool in vitreoretinal surgery, which focuses on the treatment of diseases affecting the retina and vitreous humor of the eye. The soft tip is essential for minimizing trauma to fragile ocular tissues.
Specific applications include:
Fluid-Air Exchange: This is a very common use. During vitrectomy, the vitreous gel is removed, and often the eye is filled with fluid. A soft tip cannula is used to gently aspirate this fluid while simultaneously infusing air (or another gas/silicone oil) into the eye. The soft tip ensures that the delicate retina is not damaged during this process.
Aspiration of Subretinal Fluid: In cases of retinal detachment, fluid can accumulate under the retina. The soft tip cannula allows for precise and gentle drainage of this subretinal fluid, helping the retina reattach.
Injection of Viscous Fluids or Medications: While its primary role is often aspiration, the cannula can also be used for controlled injection of various fluids or medications into the vitreous cavity or onto the retinal surface.
Gentle Retinal Manipulation: The soft tip can be used for very delicate maneuvers on the retinal surface, such as gently flattening a retinal tear or displacing small amounts of fluid without causing iatrogenic damage.
Backflush Procedures: Some soft tip cannulas are designed for "backflush" functions, where controlled aspiration or infusion is needed during complex retinal procedures.
Integration with Microincision Vitrectomy Systems (MIVS): 23-gauge instruments are part of MIVS, which utilize smaller incisions (trocar-cannula systems) for vitreoretinal surgery. This leads to benefits like faster patient recovery, reduced discomfort, and less post-operative astigmatism compared to older, larger-gauge techniques.
Why a Soft Tip is Crucial:
The retina is extremely thin and susceptible to damage. A sharp or rigid instrument could easily tear or puncture it. The soft, flexible silicone tip of this cannula provides a safety margin, allowing the surgeon to work close to or on the retinal surface with a significantly reduced risk of trauma.
