Cutter for cutting gluteal muscle contracture fascia

Abstract

The invention discloses a cutter for cutting gluteal muscle contracture fascia. The cutter includes an adjustment column, a pair of clamping frames and a pushing knife; each clamping frame has a semi-cylindrical tubular structure, and the two clamping frames are arranged symmetrically; the interior of the adjustment column is hollow, a penetrating strip-shaped groove is arranged in the axial direction of the adjustment column, the width of the strip-shaped groove is the same as the diameter of each clamping frame, and the clamping frames pass through the strip-shaped groove of the adjustment column; an adjustment handle is arranged in the adjustment column, the adjustment handle can rotate axially along the adjustment column, and the adjustment handle and the adjustment column are respectively slidingly connected with the clamping frames; and the length of the pushing knife is smaller than the length of each clamping frame, and the pushing knife is perpendicular to a cross section between the two clamping frames and is slidingly connected in the tube walls of the clamping frames. Compared with the prior art, the cutter effectively reaches a predetermined position under minimally invasive surgery, the cutter has a structure easy to operate, and the pushing knife is not easy to rotate, has high stability, and does not hurt sciatic nerves at the rear; cutters with different modelscan be selected according to the thickness of the fascia, and the adaptability is strong; and an intraoperative incision is small, and a postoperative incision is beautiful.

Description

technical field [0001] The invention relates to the field of surgical cutters, in particular to a cutter structure for cutting the contracted fascia of the gluteus muscle. Background technique [0002] At present, gluteal muscle contracture often occurs in patients with frequent intramuscular injections. Drug stimulation and needle injury can lead to chemical and traumatic myofibritis, followed by fibrous tissue hyperplasia, and then the formation of fiber contracture bands, resulting in adduction and internal rotation of the marrow joint. Dysfunction, thereby presenting a clinical syndrome with characteristic gait and signs, affecting physical and psychological development of the patient. [0003] At present, the treatment methods for gluteal muscle contracture mostly use minimally invasive surgery to cut the contracted fascia with various instruments, which has the advantages of small incision, beautiful appearance, and fast recovery. At present, the various sharp tools u...

AI Technical Summary

Problems solved by technology

At present, the various sharp tools used under minimally invasive surgery have no protective structure, which is easy to damage the tissues around the contracted fascia, especially the posterior sciatic nerve, leading to disastrous consequences; Long-term operation is easy to hold and laborious, and prone to mistakes; it is inconvenient to adjust the size and direction of the cutter according to the actual situation; it is easy to damage the sciatic nerve on the rear side when advancing backward, and the knife edge is easy to rotate, which cannot cut the contracted fascia quickly and effectively
