Average Selling Price (ASP)

The approximate range of ASP (average selling price) for the Vires針 is:

• General/OEM one-time use: Approximately ¥30–80 per unit (approximately $4–12)
• High-end European and American brands (Ethicon ENDOPATH, CONMED, Teleflex, etc.): ¥150–250 per unit

The profit comes from the quantity multiplied by the renewal rate, not from a single premium.

Typical Production Line Process

(Taking contract factories in Shandong/Guangdong/Eastern Europe as an example)

1. Raw materials arrive at the factory:
   • 304 stainless steel thin tubes (fixed to Ø ~ 2.0 – 2.1 mm, inner diameter ensuring gas flow passage)
   • ABS/PC medical resin (molded handle body)
   • Spring wire (guitar steel wire or 302 SS, custom rolled according to force value)
   • Silicone rubber ring/O-ring, three-way valve plunger, Luer nut
2. Pipe material processing:
   • CNC cutting edge bevel (the angle needs to be carefully set - too steep may cause deviation and drill jamming, too shallow may "pinch" in the fascia)
   • Electro-polishing/aging treatment → remove micro burrs and ensure corrosion-resistant surface
   • Some models have laser etching of depth scale (mm markings)
3. Subassembly:
   • Spring is inserted into the base housing → Inner core (blunt-ended preformed end) is axially inserted → Handheld halves are ultrasonically welded
   • Three-way valve is inserted into the manifold (if configured)
   • Luer-Lock thread is formed and screwed into the proximal interface
4. QC Checkpoint (Minimum Requirements):
   • Core free travel test (retraction + ejection?)
   • Simulated pneumoperitoneum pressure leak test (usually up to 20–30 mmHg)
   • Blade appearance inspection and size audit
   • Batch record traceability - As stated by factories such as TK, "16-step inspection for each piece" covers incoming certificate → work-in-progress → final aseptic barrier full chain
5. Sterilization Packaging:
   • Tyvek/zipper bag packaging → EO ethylene oxide sterilization → ventilation → packing
   • Label with batch number, expiration date (usually 3 years), sterilization indication, CE/ISO13485/FSC logo

Decision Tree from the Perspective of Procurement

Evaluation Criteria: Hospital Weightage; Reality

• Unit Price ★★★★ The difference of a few yuan × several thousand surgeries per year, which can be seen by the value analysis committee
• Surgeon Preference/Brand Trust ★★★★ The first entry tool, the surgeon has the right to veto any "unfamiliar needle"
• Regulatory Certificates (CE/FDA/ISO) ★★★ A veto item
• Supply Stability ★★★ Out of stock = delay in the next operation, the cost is much higher than the saved needle money

In recent years, the trend of "price for quantity" has driven more systems to adopt proven OEM/domestic brands - provided that the surgical team signs off. Companies like Mindray have incorporated the Viresse needle into a larger set of laparoscopic disposable instruments (grasping forceps/fixators/puncture sheath system). The Viresse is often just a lead SKU - first getting it into the operating room, and then the larger consumable baskets follow suit.
