specific Embodiment 1

[0034] The base plate 1 of the specific embodiment 1 includes an outer plate 11 and an inner plate 12, both of which are in the shape of a rectangle. Between the inner plate 12 and the outer plate 11, two sections of several tangential circular holes are arranged. A series of round holes are arranged on the upper part of the axisymmetric center line 19 , and another series of round holes are arranged on the lower part of the center line 19 . The diameters of the above-mentioned circular holes are all equal. The size of the diameter is set according to the size of the drill bit, which is slightly larger than the diameter of the drill bit. For example, there is a 2.5mm drill bit on the market, so the diameter of the round hole is set to 2.7mm. If you want to use a 3.5mm drill bit on the market, the diameter of the round hole is set to 3.7mm.

[0035] Among them, a series of circular holes in the upper part, on the left side of the inner plate 12 and above the center line 19, ...

specific Embodiment 2

[0041] The effect of the specific embodiment two is compared with the specific embodiment one. Under the same circumstances, it is not as good as the specific embodiment one. When the drill bit is drilling, the drill bit and the guide plate produce stress concentration, damage the drill bit and the guide plate, and the drill bit breaks and the guide plate breaks. .

[0042] image 3 Shown is specific embodiment three. Compared with the second embodiment, the second embodiment has two connecting parts, while the third embodiment has six connections. Except that the two positions in the middle are the same as those set in the second embodiment, the left and right sides near the short side are respectively provided with two connecting points.

specific Embodiment 3

[0043] Compared with the second embodiment, the third embodiment is less likely to separate the inner plate 12 and the outer plate 11 during the operation due to the increase of connecting parts. However, compared with the first embodiment, when the drill bit is drilling, stress concentration occurs between the drill bit and the guide plate, which damages the drill bit and the guide plate, and the fracture of the drill bit and the guide plate still exist. Moreover, there are more joints, which means that there are more bones that need to be broken during the operation.

[0044] Figure 4 Shown is specific embodiment four. Compared with the first embodiment, the difference lies in the shapes of the outer plate 11 and the inner plate 12 , and the circular holes whose positions change according to the shapes of the outer plate 11 and the inner plate 12 . In this specific embodiment, the shapes of the outer plate 11 and the inner plate 12 are semicircular on both sides and recta...

Abstract

The invention discloses a bone surgery guide plate. The bone surgery guide plate comprises an outer plate and an inner plate, wherein the outer plate and the inner plate are separated through two or more groups of a plurality of continuous round holes; gaps are formed among the groups of the round holes respectively; and two traction needle holes are arranged in the inner plate. The bone surgery guide plate provided by the invention can be used as auxiliary sheets for a bone transport surgery, and can reduce time consumption of a surgical operation.

Description

technical field [0001] The present invention relates to a device for treating bone, and relates to a plate-shaped device used as an auxiliary surgical tool during the operation on the bone. Background technique [0002] For example, toe ulcers and chronic toe ulcers caused by diabetic foot, diabetes, lower extremity arteriosclerotic obliterans, etc., can be treated with transverse bone transfer technology. [0003] The surgical procedure needs to be applied to the bone transport frame. The bone transfer frame includes a fixing frame, several fixing pins, pulling pins and other components. During the operation, it is necessary to drill a hole in the surgical site, install a fixing frame, and insert parts such as fixing pins and traction pins. [0004] In the surgical method of the prior art means, before the installation of the bone transfer frame in the surgical operation, it is necessary to mark the drilling and installation positions at the surgical site with paint or th...
