Embodiment 1

[0016] Embodiment 1: An osteotomy plate at the distal end of the first metatarsal bone, comprising a main body 4 of the osteotomy plate. The main body 4 of the osteotomy plate is a pure titanium osteotomy plate with a plate thickness of 1.5mm. The main body of the osteotomy plate adopts a reverse S-shaped design, The main body 4 of the osteotomy plate is composed of an integrally formed proximal end 1 of the osteotomy plate and a distal end 3 of the osteotomy plate, and a transition section 2 for connecting the proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate. The end 1 and the distal end 3 of the osteotomy plate are respectively provided with two fixing holes 5, and the directions of the proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate are consistent with the direction of the first metatarsal bone.

[0017] The design of the osteotomy plate and fixing screws in this embodiment is fully based on the curvature des...

Embodiment 2

[0018] Embodiment 2: An osteotomy plate at the distal end of the first metatarsal bone, comprising a main body 4 of the osteotomy plate, the main body of the osteotomy plate is a carbon steel osteotomy plate with a plate thickness of 1.5mm, and the main body of the osteotomy plate adopts a reverse S-shaped design, Such as figure 1 As shown, the osteotomy plate is composed of an integrally formed proximal end 1 of the osteotomy plate and a distal end 3 of the osteotomy plate, and a transition section 2 for connecting the proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate. The proximal end 1 and the distal end 3 of the osteotomy plate are respectively provided with three fixing holes 5 , which are distributed in a zigzag shape. The directions of the proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate are consistent with the direction of the first metatarsal bone.

Embodiment 3

[0020] Embodiment 3: A kind of osteotomy plate at the distal end of the first metatarsal bone, comprising an osteotomy plate main body 4, the osteotomy plate main body 4 is a stainless steel osteotomy plate with a plate thickness of 1.5mm, and the osteotomy plate main body 4 adopts a reverse S-shaped invention, such as figure 1 As shown, the osteotomy plate is composed of an integrally formed proximal end 1 of the osteotomy plate and a distal end 3 of the osteotomy plate, and a transition section 2 for connecting the proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate. The proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate are respectively provided with three fixing holes 5, which are distributed in a zigzag shape. The directions of the proximal end 1 of the osteotomy plate and the distal end 3 of the osteotomy plate are consistent with the direction of the first metatarsal bone.

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to an inverted S-shaped osteotomy plate body.The osteotomy plate body comprises an osteotomy plate near end, an osteotomy plate far end and a transition section used for connecting the osteotomy plate near end with the osteotomy plate far end, and the osteotomy plate near end, the osteotomy plate far end and the transition section are integrally formed; the osteotomy plate body is provided with multiple fixing holes used for fixing an osteotomy plate on the first metatarsal bone, and the directions of the osteotomy plate near end and the osteotomy plate far end are in accordance with the direction of the first metatarsal bone.According to the first metatarsal far-end osteotomy plate, osteotomy fixing is stable and reliable, the steel plate design is adopted, the strength is high, early function rehabilitation is benefited, the postoperative recovery time is shortened, and a good fixing effect on osteoporosis hallux valgus is achieved; the concealed edge design is adopted, and stimulus to soft tissue is reduced; the anatomic design is adopted, anatomical replacement after the osteotomy is convenient, and prebending of the steel plate during the operation is not needed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a first metatarsal distal osteotomy plate. Background technique [0002] Hallux valgus is a common foot disease that rarely attracts people's attention at the early stage of the disease, but with time and age, hallux valgus can gradually aggravate, and finally clinical symptoms appear. The main manifestations of the patient are pain and swelling at the bunion, and difficulty in wearing shoes and walking, which seriously affects the daily life of the patient. At this time, the deformity can be corrected surgically. [0003] At present, the most commonly used surgical method in clinic is Chevron, that is, the distal first metatarsal osteotomy. After the osteotomy was completed, the first metatarsal head was extrapolated to a satisfactory position and fixed with screws. However, the strength of screw fixation is not enough, especially for osteoporosis patients, it is easy to cause ...
