Embodiment Construction

[0015] The minimally invasive surgical scissors for cutting tendon tissue according to the present invention includes an expansion tube 1 and a probe 2 for inserting into the lumen of the expansion tube 1 . Such as figure 2 As shown, the front end of the probe 2 has a tapered needle point. Such as 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. Such as 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 expansion tube 1,...

Abstract

The invention relates to medical equipment and particularly relates to a pair of minimally-invasive surgery scissors for cutting tendon tissues. The pair of minimally-invasive surgery scissors comprises a dilating tube and a probe inserted into an inner cavity of the dilating tube, wherein a connection plate is arranged between a dilating catheter and the tube wall of the dilating tube; the connection plate is an arc plate with the same radian as the tube wall of the dilating tube; the arc length of the arc plate is less than a quarter of circumference; and moreover, the pair of minimally-invasive surgery scissors is also provided with a pair of dual-blade scissors inserted into the inner cavity of the dilating tube. The pair of minimally-invasive surgery scissors for cutting tendon tissues has the advantages of simple structure, convenience in operation and small surgical wound; and the tendon can be cut off during surgery while a section of tendon can be cut, the healing of the cut tendon is avoided, and postoperative relapse rarely happens.

Description

technical field [0001] The invention relates to a medical device, in particular to a minimally invasive surgical scissors for cutting tendon tissue. 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. The surgical method for treating carpal tunnel syndrome includes various incisions, small incision decompression and endoscopic surgery, etc. Chinese patent CN203436371U discloses "A Knife for Carpal Tunnel Syndrome 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 distin...
