Intended Use

The cannulas/needles for anesthesia and analgesia enhanced for ultrasound visibility - Spectra Sonic Block Tuohy, Spectra Sonic Block Quincke, Spectra Sonic Block Chiba and Spectra Sonic Block Crawford Needles - are intended for the transient delivery of anesthetics to provide regional analgesia or to facilitate placement of a catheter.

Device Story

Spectra Sonic Block needles are sterile, single-use, stainless steel anesthesia conduction needles featuring a dimpled echogenic tip. These dimples reflect ultrasound waves to enhance needle visibility during ultrasound-guided procedures. Available in Tuohy, Quincke, Chiba, and Crawford tip configurations, the needles are used by clinicians in hospitals, clinics, and ambulances to puncture tissue and inject anesthetics for regional anesthesia or to facilitate catheter placement. The device connects to standard Luer-lock or slip syringes. By improving needle visualization under ultrasound, the device assists the clinician in accurate needle placement, potentially reducing procedure time and improving patient outcomes during regional anesthesia administration.

Clinical Evidence

Bench testing only. Testing included biocompatibility (ISO 10993-1), sterilization validation (ISO 11135-1:2014), non-pyrogenic testing (ANSI/AAMI ST72:2011), Luer hub compatibility (ISO 594), needle bond strength (ISO 7864), and stiffness/breakage testing (ISO 9626).

Technological Characteristics

Materials: 304 stainless steel cannula, polycarbonate hub, LDPE protector, epoxy adhesive. Features: Dimpled echogenic tip for ultrasound visibility. Dimensions: 16G-26G, 20mm-180mm length. Sterilization: Ethylene Oxide (EO). Standards: ISO 594 (Luer), ISO 7864 (bond strength), ISO 9626 (stiffness/breakage), ISO 10993-1 (biocompatibility).

Indications for Use

Indicated for adult and pediatric patients requiring regional anesthesia or analgesia, or catheter placement, via transient delivery of anesthetics.

Regulatory Classification

Identification

An anesthesia conduction needle is a device used to inject local anesthetics into a patient to provide regional anesthesia.

The logo features a colorful globe on the left side, with the word "SPECTRA" in bold, black letters on the right. Below the word "SPECTRA" is the tagline "LEADING EDGE MEDICAL DEVICES" in smaller, black letters. The logo is simple, yet effective, and it conveys the company's focus on innovation and technology. The needles / cannulas for anesthesia and analgesia enhanced for ultrasound visibility are single use sterile and non-pyrogenic devices used to gain entry or puncture the tissue and inject anesthetics to induce single shot anesthesia and analgesia. The needles / cannulas may be used during all anesthesia and analgesia procedures according to the physician's indication. Needles / cannulas for anesthesia and analgesia enhanced for ultrasound visibility are standard needles /cannulas equipped with dimpled echogenic tip in order to significantly enhance ultrasound visibility. This surface technology allows for a variety of sizes. The inner diameter is not effect by the echogenic treatment. This feature completely encircles the tip of the needles / cannulas so all sides appear bright under ultrasound. In order to enhance ultrasound visibility, the needles / cannulas are equipped with a special dimpled pattern named Sonic Block dimples to the needles / cannulas surface. These reflectors are designed to optimally reflect ultrasound waves.
