The Trigger Finger Sono-Instrument® is a simple and efficient solution to treat trigger finger (percutaneous release of annular pulley(s), in particular the A1 pulley, with or without adjacent ganglion).
The Sono-Instrument® is a simple and efficient solution to treat one or several trigger fingers.
The Sono-Instrument® is presented in a single-use sterile kit, along with a probe helping in the dissection of the tissues and, at the end of the procedure, allowing to make sure that the surgical release is complete.
The procedure requires ultrasound guidance under local anaesthesia.
Our technique does not require any skin incision, stitches, or dressing. It does not result in any external blood loss.
The procedure takes a few minutes to complete, and is performed with minimal instrumentation.
Early return to daily activities
After the procedure, patients can resume their daily activities.
Cutting extremity allowing release in the plane chosen by the surgeon, safe for neighbouring tendons/ nerves/ vessels, with lateral flanges enhancing the echogenicity
Spiral groove facilitating the visualization of the Sono-Instrument® under sonography and providing information about rotatory alignment
Special design of the rod, adapted to the anatomy of the flexor digital sheath
1.5mm diameter rod, allowing insertion through the skin by a puncture made by a 14 Gauge IV catheter
Handle, allowing firm non-slip grip of the Sono-Instrument® and the maintain of its orientation throughout the whole procedure of release
1.5mm diameter smooth probe, facilitating the dissection and allowing at the end of the procedure to check the completeness of the release (note: in tight trigger fingers, there may be not enough space to use the probe at the begin of the procedure – use then directly the Sono-Instrument®)
The Sono-Instruments® are single-use sterile medical devices intended for mini-invasive hand surgery under sonography. SPIRECUT assumes that professional users have experience and knowledge of standard protocols regarding hand surgery and particularly in percutaneous release procedures under sonography. Furthermore, SPIRECUT declines any responsibility if the users have not followed lab manual-skills training with associated instrumentation prior the procedure. Surgeons are advised to review the instructions for use prior to performing any surgery.
In case of any doubt in identification of the anatomical structures or poor visibility of the Sono-Instruments® during the operation, always convert to open surgery (or stop the surgery).
The Sono-Instruments® are intended to be used solely in a medical facility, under sterile conditions, by experienced clinicians, usually surgeons, rheumatologists or radiologists, with sufficient knowledge of hand anatomy, hand surgery and sonography. Training during hands-on workshops and/or watching experienced physicians performing the operation is strongly recommended before doing the first clinical cases. Sono-Instruments® are indicated only for patients suffering of either carpal tunnel (SI-CT) or trigger finger/trigger thumb syndrome (SI-TF).
Do not use SPIRECUT’S Sono-Instruments® :
In general, all other contra-indications mentioned for endoscopic release of carpal tunnel or trigger finger/thumb are valid for percutaneous release using Spirecut’s Sono-Instruments®.
