Fixing plate and wire threading hook

Abstract

The invention discloses a fixing plate and a wire threading hook. The fixing plate can be in a rectangular sheet shape and longitudinal and cross sections can be both arc-shaped; wire threading holes (3) are formed in the fixing plate; the edge of the fixing plate is in concave-convex waveform shape (1); a wire threading holes (3) are formed in projections of the concave-convex waveform shape (1); the inner side of the edge of the concave-convex waveform shape (1) of the fixing plate is provided with ox-snout-shaped projections (2); and ox-snout wire threading holes (3) are formed in the ox-snout projections (2). The wire threading hook is formed by a U-shaped hook needle (4) and a holding rod (5); one end of the U-shaped hook needle (4) is provided with a drifting needle tip (6); an oval wire threading ole (3) is formed in the needle tip (6); and the other end of the U-shaped hook needle (4) is connected with the holding rod (5). Small operation trauma is caused; the fixing plate and the threading hook can be simply structure and meet minimally invasive principle; foreign matter discomfortableness can be reduced for a patient after a surgery; great chest wall adaptability is achieved; steel plate anaphylaxis can be avoided; and steel plate detachment after the surgery can be unnecessary.

Description

technical field [0001] The invention relates to a fixing plate and a thread passing hook. Specifically, it is a fixed plate used by rib fractures and a special tool wire hook for fixing the fixed plate. Background technique [0002] Rib fracture is the most common thoracic trauma, and tens of thousands of patients with rib fracture undergo surgical treatment every year. Products related to rib fracture fixation include: 1. Imported products: A. Absorbable products: such as rib intramedullary nails with pointed ends that can be inserted into the second broken ends of ribs for fixation. There are also flat, long strips, with a slight longitudinal radian, and fixed holes along the longitudinal axis. By drilling holes in the ribs, they can be fixed on the fractured ribs with absorbable screws or sutures to fix rib fractures. B. Non-absorbable product: Johnson & Johnson’s titanium alloy rib fixation plate. The shape and fixing method are basically the same as the absorbable rib...

Problems solved by technology

[0003] Absorbable rib intramedullary nails have disadvantages such as difficulty in installation, poor fixation effect, and high cost, and are rarely used clinically. Absorbable rib fixation plates have not yet entered the Chinese market, and they are also installed in the same way as imported titanium alloy rib fixation plates. The procedures are complicated, the damage is large, minimally invasive surgery is not suitable, and the cost is expensive. In addition, metal products have disadvantages such as non-absorption, local foreign body sensation, and possible allergies and discomfort to the steel plate. Some patients need surgery to remove them after surgery. Therefore, it is difficult to popularize and apply. Although domestic rib bone plate is easier to install than imported plate, it needs to separate the rib and intercostal muscle, which will damage the periosteum and intercostal muscle of the rib, and affect the blood circulation and regeneration of the rib. The healing of rib fractures, when the ribs are embraced, the ribs will be squeezed and the ribs will be deformed and cause new injuries or fractures. The high hardness of the metal will reduce the compliance of the local chest wall and have a relatively greater impact on breathing. Local foreign bodies and discomfort are more severe. Strong, so some patients strongly demand reoperation to remove foreign body
