Sono-Instruments®:
Minimally Invasive Solutions for Trigger Finger & Carpal Tunnel Release
Sono-Instruments®, developed by Swiss innovators Spirecut, are precision-engineered microinstruments created specifically for ultrasound-guided soft tissue procedures. Built around real-time imaging and fine anatomical control, these instruments are enabling a new wave of physician-led interventions, with reduced surgical footprint, faster recovery, and lower costs.
Why Choose Ultrasound-Guided Release?
Ultrasound-guided release is a safe, effective alternative to traditional open or endoscopic surgery, without the need for theatres, sutures, or post-op wound care.
Using high-resolution ultrasound imaging, clinicians can precisely identify anatomical structures in real time, ensuring targeted release of the transverse carpal ligament or A1 pulley while avoiding surrounding nerves, vessels, and tendons.
Combined with sterile single-use instruments and a 1.5 mm access point, procedures can be done quickly in outpatient procedure rooms using only local anaesthetic.

Clinical Applications
Trigger Finger Release
Percutaneous release of the A1 pulley
Using Sono-Instruments®, physicians can release the affected pulley through a 1.5 mm incision under real-time ultrasound guidance. The approach avoids tendon or nerve damage, and dramatically reduces post-op stiffness and scarring commonly seen in open procedures.
Carpal Tunnel Release (CTR)
Targeted division of the transverse carpal ligament
Ultrasound guidance allows precise identification of the median nerve and surrounding structures. With Sono-Instruments®, the TCL is safely released via a percutaneous approach, protecting vascular structures and minimising soft tissue disruption.
