Blunt-tip dermal filler microcannula (CSH \u2013 Closed Single Hole)
Description
The TSK CSH Cannula 25G x 50mm (2.0 inch) is a closed-tip, side-hole, blunt dermal filler microcannula designed for use with hyaluronic acid (HA) and non-HA dermal fillers. It features ultra-thin wall technology, a dome-shaped tip and proprietary surface treatment to provide up to approximately 50% better gliding compared with traditional cannulas. The CSH design offers low penetration force, improved control, reduced risk of bruising and smoother, more precise filler placement. Supplied as a medical-use box of 25 single-use sterile cannulas.
Bnefits
Blunt closed-tip with side port reduces the risk of vascular injury compared with sharp needles when used by trained professionals.
Ultra-thin wall technology increases internal diameter, reducing extrusion force (up to ~35% less) and allowing smoother, more controlled injection.
Proprietary surface treatment reduces friction with tissue, delivering up to approximately 50% better gliding under the skin and improving patient comfort.
Dome-shaped tip and refined geometry help easier cannula introduction through the entry point while reducing tissue trauma and bruising.
Closed single-hole (CSH) design with lateral side port allows nearest-to-tip filler delivery, enabling accurate product placement and reduced product loss.
Optimised flexibility and PRC (Precise Revolution Control) hub design help maintain cannula direction and tactile feedback, enhancing injector control.
25G x 50mm size provides a good balance of reach and manoeuvrability, allowing treatment of a larger area from a single entry point and reducing the number of skin punctures.
Manufactured from high-quality surgical stainless steel with CE-marked, sterile, single-use construction for consistent performance.
Indications
Intended for use by trained healthcare professionals for subcutaneous and superficial injections of dermal fillers in aesthetic medicine.
Suitable for HA and non-HA dermal fillers where a 25G x 50mm blunt cannula is clinically appropriate.
Common facial applications include midface, cheeks, jawline, nasolabial and marionette areas, temples and other regions as determined by the treating practitioner.
Surface: proprietary low-friction surface treatment for improved gliding characteristics.
Connection: standard luer-lock PRC hub compatible with most dermal filler syringes.
Sterility: EO-sterilised, single-use, supplied individually blister-packed within a box of 25.
Packaging
Box containing 25 TSK CSH Cannulas 25G x 50mm.
Each cannula is individually packaged in a sterile blister or capsule pack.
Outer box labelled with product name, gauge, length, CSH type, lot number, expiry date and regulatory markings (including CE mark where applicable).
Intended for professional/medical use; some markets require proof of medical license to purchase.
Usage
For medical use only; must be used exclusively by appropriately trained and qualified healthcare professionals experienced in dermal filler injections.
Prepare the treatment area using appropriate aseptic technique, including thorough skin cleansing and disinfection.
Create a small entry point using a separate sharp introducer needle of appropriate gauge at the desired entry site, following safe injection guidelines.
Attach the TSK CSH cannula securely to a luer-lock syringe prefilled with the chosen dermal filler; ensure the hub is firmly seated.
Introduce the blunt cannula gently through the pre-made entry point into the desired tissue plane (typically subcutaneous or deep dermis depending on indication).
Advance the cannula with slow, controlled movements, following anatomical safe planes and avoiding excessive force; adjust direction as needed using tactile feedback from the PRC hub.
Inject filler slowly and incrementally while withdrawing or repositioning the cannula, according to the chosen injection technique and product instructions.
Avoid intravascular injection: aspirate in accordance with clinic protocol where appropriate, monitor for pain, blanching or other signs of vascular compromise, and stop injection immediately if suspected.
Upon completion, remove the cannula, apply gentle pressure and, if indicated, cool compression to reduce bruising.
Dispose of used cannula and introducer needle immediately in an approved sharps container; device is single use only and must not be re-sterilised or reused.
Contraindications
Do not use in patients for whom dermal filler injections are contraindicated according to the filler manufacturer’s instructions or clinical guidelines.
Do not use on or through areas of active infection, inflammation, dermatitis, open wounds or compromised skin at or near the injection site.
Do not use in patients with known hypersensitivity to stainless steel or other components of the device.
Do not use if the sterile packaging is damaged, opened, or beyond its expiry date.
Device is intended for single use; do not re-use, reprocess or re-sterilise.
Use with particular caution in patients with bleeding disorders or those on anticoagulant or antiplatelet therapy, due to increased risk of bruising or bleeding.
Adverse Effects
Local injection-site reactions associated with dermal filler procedures, such as temporary pain, tenderness, redness, swelling or bruising.
Bleeding or haematoma at the entry point or along the cannula track.
Rare risk of infection if aseptic technique is not strictly followed.
Tissue trauma, nodules or irregularities related to injection technique or filler placement rather than the cannula itself.
Potential vascular complications, including ischaemia or necrosis, if filler is inadvertently injected into or compresses a vessel; the blunt cannula design aims to reduce but does not eliminate this risk.
Rare hypersensitivity or allergic reactions to device materials in susceptible individuals.
Storage Conditions
Store in a clean, dry environment at room temperature, away from excessive heat, moisture and direct sunlight.
Keep cannulas in their original packaging until use to maintain sterility and protect from mechanical damage.
Do not use after the expiry date indicated on the packaging.
Protect from crushing, bending or other mechanical stress that could damage the cannula or hub.
Duration
The cannula is a single-use delivery device; it is used for the duration of a single injection session and then discarded. Overall treatment duration and frequency are determined by the dermal filler product and clinical treatment plan, not by the cannula itself.
Onset
Not directly applicable to the cannula itself. Aesthetic effects occur immediately following proper placement of dermal filler and evolve over time according to the properties of the injected product.
