Product Description

304 Stainless Steel Cnc Medical Metal Processing Parts

Product Description

Product Application:
This is a precision-engineered fluid delivery component designed for medical devices requiring secure, leak-free connections and controlled, atomized spray patterns. Its dual-thread design ensures reliable integration into complex medical systems.

Minimally Invasive Surgery: As a key component in laparoscopic irrigation/suction devices, used for clearing the surgical field and delivering therapeutic fluids.
Wound Debridement & Cleansing: Integrated into high-pressure wound irrigation systems (e.g., pulsed lavage) to effectively remove debris and bacteria.
Aerosol Drug Delivery: Serves as the precision nozzle in nebulizers or inhaler actuators, generating the fine mist required for respiratory treatment.
Endoscopic Procedures: Used in arthroscopic and hysteroscopic systems for joint or cavity distension and cleansing.
Diagnostic & Dental Equipment: Functions as a spray tip in dental air/water syringes or as a sample introduction nozzle in analytical instruments.
 
Product Description:
We manufacture high-precision double-threaded spray needles from medical-grade 304 stainless steel tubing using advanced CNC machining technology. This component uniquely integrates two separate threaded sections on a single hollow needle body. One thread (typically at the proximal end) provides a robust, standardized connection (e.g., Luer-lock) to a fluid source or handpiece. The second thread (often at the distal end or mid-section) allows for the secure attachment of a specialized, interchangeable spray tip or diffuser that dictates the spray pattern (fan, cone, jet). The internal channel is meticulously machined to ensure consistent, laminar flow. The entire part is crafted from corrosion-resistant 304 stainless steel, making it durable, autoclavable, and suitable for repeated sterilization cycles. We offer complete customization of all dimensions, thread specifications (metric, UNF, Luer), spray orifice geometry, and overall configuration to meet exact OEM device requirements.
