Fracture fixing steel plate and steel plate fixing system

Abstract

The present invention provides a fracture fixing steel plate and a steel plate fixing system and relates to the technical field of medical devices. The fracture fixing steel plate comprises a steel body portion and fixing portions for fixing the steel body portion, at least two through-holes penetrating a first surface and a second surface are arranged in the steel body portion, the through-holesare used for passing of steal wires, and the fixing portions are arranged on the second surface of the steal body portion. Due to the fact that at least two through-holes penetrating the first surfaceand the second surface are arranged in the steel body portion of the fracture fixing steel plate, both ends of the steel wires can penetrate into the through-holes at both sides from the first surface of the steel body portion to penetrate out from the second surface of the steel body portion, under a cooperation of an arthroscope, the steel wires can pull the fracture fixing steel plate to a fracture portion from in vitro in a pre-route, thus the fixing portions arranged on the second surface of the steel body portion can be fixed on a fracture block portion to effectively fix fracture blocks; since the fracture fixing steel plate can be introduced into the fracture portion from in vitro, operations are convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fracture fixation plate and a plate fixation system. Background technique [0002] At present, there are many methods for treating avulsion fractures of the insertion point of the anterior fork ligament in the field of orthopedics in China. In the past, the bone was fixed by direct hollow nails, steel wires, thick wires, and retrograde Kirschner wires through arthrotomy. Later, due to the large trauma, It is not conducive to the recovery of joint function and is gradually eliminated. With arthroscopic technology (arthroscopic technology is to insert a lens metal tube with lighting device into the joint cavity through a small incision, and enlarge the internal structure of the joint cavity on the monitor to observe the lesions and parts of the joint cavity , and at the same time conduct a comprehensive inspection and clean up the lesion under TV monitoring) mature and e...

Problems solved by technology

However, due to the limitation of the operating space under arthroscopy and many uncontrollable factors, the operation time is often greatly prolonged. Hollow nail fixation often causes the fixation angle to be too small due to the obstruction of the patella, which will push the bone block and cause displacement, thereby affecting the fixation effect; The steel wire (thick wire) needs to pass through the anterior fork ligament to cause iatrogenic ligament damage during fixation. Retrograde Kirschner wire fixation may cause bone fragments to be lifted and shifted like rubbing, which also affects the fixation effect.

Therefore, the traditional fracture fixation methods have disadvantages such as difficult operation, not smooth, poor fixation effect, etc.

The main reason for the above-mentioned shortcomings is that it needs to be operated under the arthroscope, which will bring about the limitation of the operating space, and there are often phenomena that cannot be seen or done.
