Description

Orthopedics external fixation support that single section and multistage fracture two dimension screw thread adjustment reset

Technical Field

The utility model belongs to the technical field of orthopedics and plastic surgery surgical instruments and specifically relates to an orthopedics external fixation support that single section and multistage fracture two dimension screw thread adjustment reset is related to.

Background

At present, methods such as fracture incision reduction, bone screw, threaded needle, steel plate or intramedullary needle internal fixation for treating fracture and the like have defects, an orthopedic external fixator capable of performing three-dimensional space thread adjustment on a fracture block is few clinically, only American taylor brackets can perform three-dimensional space thread adjustment at present, but the taylor brackets also have defects and are few clinically applied. Besides, the orthopedic external fixator capable of performing two-dimensional space thread adjustment on a fracture block is rare, most orthopedic external fixing supports only have the function of one-dimensional space thread adjustment (elongation and shortening), the existing one-dimensional space thread adjustment fixing support can only correct the separation or the overlapping of fracture axes, and when the fracture has an angled axis and the axis moves forwards and backwards or leftwards and rightwards, the thread adjustment and the reduction are difficult.

The existing single-arm orthopedic external fixator is mainly used for temporary external fixation of fracture, has no function of restoration, is often not well aligned after being fixed by the orthopedic external fixator, needs to be removed for the second time, and adopts fracture incision restoration and internal fixation of steel plates or intramedullary needles to treat fracture.

The prior fracture external fixing supports disclosed in Chinese patents CN200410037918 and CN200420064654 mainly aim at the reduction and stable fixation of dislocation of one fracture line of a skeleton, but the reduction and fixation of multiple sections of fractures by a single set of orthopedic external fixing support are rarely reported. Meanwhile, the problems that the orthopedic external fixator is easy to slip or loosen when force is applied due to the design of a linear knob for adjusting or locking the head of the screw, the connection design for fixing the screw and the rod body is not firm, the screw is easy to loosen and pull out and the like exist. In addition, when the early function of the limb joint is exercised, the steel needle and the backbone generate rotary movement, which causes damage and pain to tissues. The distance between spicules fixed on the bone blocks at two ends of the fracture line is long, so that the bone pins can not be adjusted and shortened, the bone pins are only suitable for oblique fracture, when the bone pins are in transverse fracture, the bone pins can not be adjusted and shortened due to long distance, so that the fracture is not fixed stably, different types of fracture are limited, and the fracture treatment effect is influenced.

In a word, the existing single set of orthopedic external fixation support at home and abroad has few varieties of orthopedic external fixators which can perform two-dimensional threaded adjustment reduction on multi-section fractures of long bones of limbs, and the requirements of accurate alignment and convenient adjustment of clinical multi-section fractures are difficult to meet.
