Embodiment Construction

[0015] The minimally invasive surgical instrument for carpal tunnel syndrome of the present invention includes a dilation tube 1 and a probe 2 for being inserted into the lumen of the dilation tube 1 . like figure 2 As shown, the front end of the probe 2 has a tapered needle point. like figure 1 As shown, the front end of the expansion tube 1 is provided with an expansion tube 3, the expansion tube 3 is coaxially arranged with the expansion tube 1 and has the same diameter, and a connecting plate 4 is arranged between the expansion tube 3 and the wall of the expansion tube 1, The connecting plate 4 is an arc-shaped plate equal to the curvature of the tube wall of the expansion tube 1, and the arc length of the arc-shaped plate is less than 1 / 4 of the circumference. like Figure 5 As shown, the cross-sections of the expansion tube 1 and the probe 2 are both elliptical. In the first step of the operation, the probe 2 is first inserted into the stretch tube 1, and the tapered...

Abstract

The invention relates to a medical instrument, in particular to a minimally invasive surgery instrument for carpal tunnel syndrome. The instrument comprises an expansion tube and a probe used for being plugged in an inner cavity of the expansion tube, a connecting plate is arranged between a dilating catheter and the tube wall of the expansion tube, the connecting plate is an arc plate with the radian equal to that of the tube wall of the expansion tube, and the arc length of the arc plate is smaller than one fourth of circumference; the instrument is additionally provided with dual-blade scissors plugged into the inner cavity of the expansion tube. The minimally invasive surgery instrument for carpal tunnel syndrome is simple in structure, convenient to operate and small in surgical wounds and can cut off tendons in surgery and cut off a section of tendon, and the cut-off tendons are prevented from healing and less prone to relapsing after surgery.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a minimally invasive surgical instrument for carpal tunnel syndrome. Background technique [0002] Carpal tunnel syndrome is the most common peripheral nerve entrapment disease. The cause of carpal tunnel syndrome is that the pressure in the carpal tunnel increases and the median nerve is entrapped. Surgical methods for the treatment of carpal tunnel syndrome include various incisions, small incision decompression and endoscopic surgery. Endoscopic technology is a "minimally invasive" surgical treatment method, with small incisions and minimal trauma, which can avoid postoperative incision discomfort and other problems. At present, there are many literatures on the use of various endoscopic techniques. However, there are still some problems, such as iatrogenic nerve injury, poor visual field, inability to distinguish anatomical variation, insufficient release, and high cost. If the field...
