Abstract
A device for treating trigger thumb or trigger finger may include a handle, an introducer shaft extending from the handle, a blade shaft slidably disposed on the handle and the introducer shaft, a blade at or near a distal end of the blade shaft, a slider on the handle, attached to a proximal end of the blade shaft, for sliding the blade shaft and the blade distally and proximally along the introducer shaft, and a neurovascular guard slidably coupled with the handle and disposed over at least part of the blade shaft. The neurovascular guard may be made of a material that allows passage of ultrasound waves, such as Ultem, PEEK, PPS, or other polymers.
Claims4
A method for treating a thumb of a patient, the method comprising:
- advancing an introducer shaft of a treatment device under an A1 pulley of the thumb, between the A1 pulley and a flexor pollicis longus (FPL) tendon of the thumb, wherein the introducer shaft is coupled with a handle of the treatment device;
- sliding a guard handle along the handle of the treatment device to advance a neurovascular guard shaft of the treatment device along the shaft and over the A1 pulley, such that a gap remains between a distal tip of the neurovascular guard shaft and a distal tip of the introducer shaft;
- rotating a blade slider approximately 90 degrees relative to the handle to expose a blade out of the gap between the distal tip of the introducer shaft and the distal tip of the neurovascular guard shaft and to position the blade in a vertical, cutting position;
- retracting the blade by sliding the blade slider proximally along the handle to cut the A1 pulley;
- and removing the treatment device from the thumb.
