Abstract

The invention relates to a guiding-type cutting knife assembly and a guiding device thereof. The guiding device comprises a guiding part, and a blade rail is formed in the guiding part and extends to the tail end of the guiding part. The guiding-type cutting knife assembly comprises the guiding device and a cutting knife, and the sliding side of the cutting knife is connected with the blade rail of the guiding device in a sliding mode. The guiding device has the multiple functions such as probing, positioning, guiding, opening, protecting and measuring; according to the accurate positioning function, accurate guiding function and safe protection effect of the guiding device, subsidiary injuries of the flexor tendon structure, digital nerve and vessel structure and the like are reduced or avoided, the scale measuring function of the guiding device is used, and the accurate and scientific judgment criteria is provided for whether an A1 tackle during operation is completely released or not so that the post-operation disease-condition recurrence rate can be reduced.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a guiding cutter assembly and its guide. Background technique [0002] Stenosing tenosynovitis of finger flexor tendon is a common disease in orthopedics. The etiology is that repetitive strain or cold stimulation lead to hyperplasia and hypertrophy of the A1 part of the pulley of finger flexor tendon, which narrows the tendon sheath of finger flexor tendon and compresses the tendon, resulting in tendon edema and hindering tendon sliding. , The affected fingers are often painful and uncomfortable, and in severe cases, joint locking may occur. [0003] At present, in medical clinical work, the minimally invasive release treatment of finger flexor tendon stenosing tenosynovitis is more and more widely used. Compared with traditional open surgery, minimally invasive surgery has the advantages of small surgical incision, short treatment cycle, and quick recovery. There ar...
