Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only illustrative of the present invention and do not limit the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figures 1, 2 and 7, the individualized bone cement prosthesis plastic mould for joint infection comprises two rotatably connected box bodies 1, wherein a left box body 1 and a right box body 1 are arranged in mirror symmetry, the hollow sides of the two box bodies 1 are opposite, a first supporting plate 2 is fixedly connected in each box body 1, as shown in figure 3, a second supporting plate 3 fixedly connected with the box bodies 1 is arranged on the right side of each first supporting plate 2, a plurality of rows of fine through holes 4 are formed in each first supporting plate 2, a first push rod 5 is slidably connected in each through hole 4, a second push rod 6 penetrating through each second supporting plate 3 is fixedly connected at the right end of each first push rod 5, a spring 7 is sleeved outside each first push rod 5, the left end of each spring 7 is fixedly connected with each first push rod 5, the right end of each spring 7 is fixedly connected with each second push rod 6, a limit ring 8 abutting against each second supporting plate 3 is arranged at the left end of each second push rod 6, as shown in fig. 4, the activity groove 9 has all been opened to 6 right-hand members of second push rod, the internal rotation of activity groove 9 is connected with moulding piece 10, all install positioning mechanism in the box body 1, as shown in fig. 5 and 6, positioning mechanism is including installing the bolt 11 at 1 upside of box body, threaded connection has set nut 12 on the bolt 11, set nut 12 installs the diaphragm 13 with bolt 11 sliding connection's top, the equal fixedly connected with in both ends stretches into the inside riser 14 of box around diaphragm 13, a plurality of locating plates 15 of fixedly connected with between two riser 14, be equipped with the constant head tank 16 that a plurality of and first push rod 5 correspond on the locating plate 15, constant head tank 16 is "T" shape setting down, open 1 upside of box body has filled the hole, locking mechanism is all installed in two 1 outsides of box body, this example locking mechanism is the hasp.
