A Hallux Valgus Base Closed Wedge Osteotomy Guide

Abstract

The invention relates to a hallux valgus substrate occlusion wedged osteotomy guider. The hallux valgus substrate occlusion wedged osteotomy guider comprises a planta pedis support, an ankle support, a vertical rod and an osteotomy device, wherein the ankle support is perpendicularly connected with the planta pedis support, guide rails are arranged on the two sides of the planta pedis support respectively, the bottom of the vertical rod is fixedly connected with a guiding sliding block which is matched with the corresponding guide rail, laser locators are arranged at the tail ends of the two sides of a wedged osteotomy guide block respectively, the osteotomy device is connected with a through hole in a rotary mode through the vertical rod, an angle locating hole which is matched with a locating guide needle is formed in one side of a scale, an extended circular-arc-shaped measuring plate is arranged on the edge of the other side of the scale, a stirring block is arranged at the upper end of the extended circular-arc-shaped measuring plate, and the scale is movably connected with the wedged osteotomy guide block in the mode that the locating guide needle penetrates through the angle locating hole and first locating needle holes in sequence. The hallux valgus substrate occlusion wedged osteotomy guider is accurate in locating and easy to operate, and facilitating operation of beginners.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a hallux valgus base closed wedge osteotomy guide. Background technique [0002] Basal wedge-shaped closing osteotomy is a kind of basal osteotomy, and it is accepted by most doctors because of its strong orthopedic ability in the treatment of hallux valgus. Loison first mentioned this osteotomy in 1901, and Balacescu used it in clinical operations in 1903. In the 1960s and 1970s, doctors continued to use this technique to treat hallux valgus, and after the 1980s, literature began to be published. The mathematics and geometry research of this osteotomy also started relatively early. As early as 1984, some scholars conducted mathematical research on this osteotomy. In 1985, JahssMH et al conducted a mathematical and geometric study on 120 feet treated (75 patients with hallux valgus) using 5 osteotomies. In the 1990s, it was a smash hit. However, with the deepening of ...

Problems solved by technology

In order to avoid appealing complications, this operation has been continuously improved and has become one of the classic operations for the treatment of hallux valgus. However, most scholars pointed out that this operation is difficult and requires a certain learning curve, which is not conducive to beginners.

The main reason is that the direction of osteotomy and the amount of osteotomy cannot be accurately determined.
