The invention is further described below with reference to fig. 1 and 2.
The orthopedic guide assembly comprises a fixed needle 20, at least two guide frames 10, a plurality of guide pipes 30 and a plurality of positioning needles, wherein the guide frames 10 are semicircular, and the diameters of the guide frames 10 are different from each other. In this embodiment, the number of the guide frames 10 is three, and the diameters of the guide frames are 100mm, 150mm and 200mm, so that the guide frames can be suitable for limbs with different positions and different thicknesses.
In this embodiment, the outlet end of the guiding tube 30 is in a tooth structure, which can be tightly attached to the bone surface, so as to avoid the deviation in the guiding process.
In this embodiment, the positioning needle has a plurality of lengths. The number of the positioning needles is eight, and the lengths of the positioning needles are different.
One end of the guide frame 10 is formed with a first through hole for mounting the fixing needle 20, and the other end of the guide frame 10 is formed with a second through hole, the axes of which are collinear. The diameter of the second through hole, the outer diameter of the guide tube 30 and the diameter of the positioning needle are equal, and in this embodiment, the diameter of the second through hole is 5.0mm.
A plurality of third through holes 13 are arranged on the guide frame 10 along the direction from one end to the other end, the specifications of the third through holes 13 and the second through holes are the same, and the central axis of each third through hole 13 and the central axis of the first through hole are converged at one point. In this embodiment, the third through holes 13 are sequentially arranged along the direction from the end of the second through hole to the end of the first through hole on the guide frame 10.
The orthopaedics guide device can realize opposite straight drilling and multi-angle oblique drilling.
In this embodiment, the side of the fixed needle 20 is marked with a scale, which starts from the tip of the fixed needle 20. When the fixed needle scale is placed at 30mm (i.e. the length of the needle point of the fixed needle 20 penetrating through the first through hole is 30 mm), the position of the needle point of the fixed needle 20 is the intersection point of the central axis of the third through hole 13 and the central axis of the first through hole, i.e. the position of the needle point of the fixed needle 20 is the positioning point.
