Problems solved by technology

In order to make the locking screw implanted in the bone have the best fixation effect, it is required that the locking screw must be implanted in the bone in a specific direction; due to the different parts of the fracture and the bone shape between different individuals, there are differences. In clinical application, this locking plate screw system often has a contradiction between the set implantation direction and the optimal implantation direction between the locking screw and the plate, which affects the surgical effect

Embodiment Construction

[0017] Such as figure 1 The embodiment shown is a universal locking pressurized bone plate, in which several universal locking holes 1 are set at the head of the bone plate 5, several Kirschner wire holes 2 are set at the head and the rod, and the tail is set by adding Combining hole 3 formed by partially overlapping the pressing hole groove and the locking hole.

[0018] The Kirschner wire holes 2 in the rod portion of the present invention are distributed symmetrically, thereby increasing the stability.

[0019] Such as figure 2 , 3 As shown, the universal locking hole 1 of the present invention is composed of a tapered threaded hole 11 and an arc-shaped groove 12. The tapered threaded hole 11 is composed of an arc-shaped counterbore 111 and a tapered threaded hole 112. The taper of the tapered threaded hole 112 is 0-30°, the arc-shaped groove 12 is composed of four arcs evenly distributed.

[0020] Such as figure 2 , Figure 6 , Figure 7 As shown, the universal lo...

Abstract

The invention belongs to medical equipment, and particularly discloses a universal locking and pressurizing bone plate. The universal locking and pressurizing bone plate is characterized in that a plurality of universal locking holes are formed in the head part of the bone plate; both the head part and the rod part of the bone plate are provided with a plurality of Kirschner wire holes; and the tail part of the bone plate is provided with combination holes formed by partly overlapping pressurizing hole slots and the locking holes. The universal locking holes of the universal locking and pressurizing bone plate allow locking screws to be set at certain angles in all directions away from the axis and the angles are 0 to 15 degrees. The universal locking and pressurizing bone plate disclosed by the invention can select an angle in the range of plus and minus 15 degrees or a preset fixed angle by a tool during operation so as to conveniently select a fixing method according to a fracture fragment. Meanwhile, the Kirschner wire holes are used for temporary fixation of the bone plate, so that the stability of a product is improved so as to ensure the success of operations and reduce pain of patients. The universal locking and pressurizing bone plate has a reasonable structure, is simple to manufacture and flexible to use, has an ideal effect and the advantages of large embedded direction selection range and good locking effect.

Description

technical field [0001] The invention belongs to the category of medical instruments, in particular to a universal locking pressurized bone plate. Background technique [0002] The clinically used locking plate system for orthopedic internal fixation is mainly composed of locking screws and plates, which we call locking plate screw systems. In locking plate screw systems, the angle between the locking screw and the plate is pre-set. In order to make the locking screw implanted in the bone have the best fixation effect, it is required that the locking screw must be implanted in the bone in a specific direction; due to the difference in the fracture and broken parts, and the difference in the shape of the bone between different individuals, therefore In clinical application, this locking plate screw system often has a contradiction between the set implantation direction and the optimal implantation direction between the locking screw and the plate, which affects the surgical e...
