Embodiment Construction
[0025] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0026] Such as Figure 1-5 As shown, what is described in the embodiment of the present invention is a ligament fixation system containing filled bone blocks. The ligament fixation system is a bone-ligament-bone model, including:
[0027] The filled bone block 4 is cylindrical. The cylindrical surface of the filled bone block 4 is symmetrically provided with four U-shaped grooves along its height direction. The coil 5 is wound on two oppositely arranged U-shaped grooves. Filling bone blocks 4 whose ends are in contact with each other run through the bone tunnel 9;
[0028] There are two steel plates 1, which are respectively arranged at the two ends of the bone tunnel 9 outside the bone tunnel 9. The steel plate 1 is provided with a plurality of symmetrically arranged threading holes 7, and each filling bone block 4 passes th...

The invention relates to a ligament fixation system containing filling bone blocks. The ligament fixation system in a bone-ligament-bone mode and comprises the filling bone blocks, two steel plates and a ligament, wherein the filling bone blocks are cylindrical, four U-shaped grooves are symmetrically formed in the cylindrical surface of each filling bone block in the height direction of the filling bone block, two opposite U-shaped grooves are wound with a coil, and the filling bone blocks with the two bottoms making contact with each other penetrate into a bone channel; the two steel platesare arranged at the portions, close to the two end openings of the bone channel, on the outer portion of the bone channel respectively, a plurality of symmetrical threading holes are formed in the steel plates, and each filling bone block is connected with the corresponding steel plate through a sleeve ring; the ligament penetrates through the whole bone channel, the two ends of the ligament penetrate through the corresponding sleeve rings respectively, and the portions, superposed with the filling bone blocks, of the ligament are arranged on the other two opposite U-shaped grooves of the filling bone blocks.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a ligament fixation system containing bone filling blocks. Background technique [0002] At present, in soft tissue and anterior cruciate ligament reconstruction operations at home and abroad, bone tunnels need to be drilled out of positioning considerations. In the traditional ligament repair mode, extrusion screws are used to fix the ligament in the bone canal, and the healing purpose is achieved through the natural healing and growth of the bone and ligament. According to different physiques, patients generally heal the bone canal naturally within 4-6 months after surgery. However, due to the repeated scouring stimulation of human tissue fluid and the wiper effect of positioning sutures, there is a certain probability of inflammation in the bone tract, which will delay the healing of the bone tract and even cause the failure of the ligament positioning operation. Con...
