Description

Flat double-edge scale needle knife
Technical Field
The utility model belongs to medical equipment for traditional Chinese medicine orthopedics and traumatology, and particularly relates to a flat-mouth double-edge needle knife with scales.
Background
Ganglion cysts are benign soft tissue tumor common in hands, and are caused by long-term excessive friction between tendons and tenosynovium, and traumatic inflammation. The bone disease patient is easy to cause large-scale damage by operation at the positions of the radius styloid process and the flexor tendon, the traditional Chinese medicine needling treatment effect is poor, the needle knife medicine has the functions of western medicine operation cutting and separation and traditional Chinese medicine needling, is the result of combination of the traditional Chinese medicine and the western medicine, utilizes the needle knife medicine bone disease to carry out minimally invasive and loosening treatment, and can play a good curative effect. Because of the delicate and complex structure of the tendon sheath and its surrounding tissues, special care should be taken to avoid injuring the blood vessels and nerves on both sides of the tendon during needle knife treatment. The existing needle knife heads comprise a flat edge, an oblique edge, a concave edge and a crochet hook shape, but the needle knife has the following defects in the actual treatment process:
1. the flat-edge needle knife is characterized in that a needle point is provided with a horizontal edge with a downward cutting edge, the flat-edge needle knife is used for cutting, a needle is rapidly advanced at a pain point to achieve longitudinal cutting of the surface of a tendon sheath, the flat edge is positioned at the needle point, the cutting edge is downward, and if the tendon sheath is punctured, the flat edge is positioned under the sheath and is difficult to push longitudinally.
2. The oblique blade needle knife is characterized in that an oblique cutting edge which is obliquely downward is arranged on one side of a needle point, the oblique cutting edge is generally 0.8mm long, tendon sheaths are generally about 10mm long, one direction cannot be completely cut, the knife is required to be retracted, the 180-degree direction is adjusted, and the other direction is reversed for cutting again. Two needle insertion is needed, and the needle insertion point is not easy to be on the same point.
3. When the distal and proximal ends of tendon sheath are positioned by pushing with concave blade and pulling with a hook needle and knife, the method is that the doctor presses the pain point of the affected finger with thumb and then makes the patient fully flex the metacarpophalangeal joints and interphalangeal joints. When bending the finger, the scleroma slides to the proximal end of the tendon sheath (namely, the starting part of the tendon sheath of the cursory finger), when stretching the finger, the scleroma slides to the distal end of the tendon sheath, and the affected finger is repeatedly bent and stretched, so that the enlarged nodule can feel that the enlarged nodule moves at the distal end and the proximal end of the stenosed tendon sheath, and the interval between the enlarged nodule and the stenosed tendon sheath is the length of the stenosed tendon sheath. For patients with severe pain and no clamping pressure, the far and near ends cannot be determined, and the pain is severe and aggravated when the patient is clamped and pressed to bend and stretch. After the far and near ends are determined, the needle is inserted at the position of 0.5cm far from the pressure pain point, and the distance and depth are not easy to grasp.
4. The needle knife has no scale, and the needle inserting depth is not easy to master.
The problems are that when a patient is treated, pain is aggravated, side injury is easy to generate, accurate positioning cannot be realized, the skill requirement on an operator is high, and the popularization and the use of the knife needle therapy are affected.
