Embodiment Construction

[0031] Such as figure 1 As shown, the external fixation device with reduction function. It consists of guide rail (1), bone needle clamp (2), tuning handle (3), hinge (4), tuning system (5), expansion nut (6), locking screw (7), turning handle ( 8) Composition. The two guide rails (1) are screwed on the sides of the hinge (4) respectively, and the bone needle clips (2) are respectively worn on them, and the extension nuts (6) are screwed on both sides of the bone needle clips (2), and the bone needle clips The side of (2) is designed with locking screw (7), and tuning handle (3) is screwed on the termination of hinge (4) respectively, and the side of hinge (4) wears tuning system (5). When the fracture site is put on the bone needle and clamped to the corresponding place of the bone needle clamp (2), the turning handle (8) is fastened on the corresponding bone needle.

[0032] The guide rail (1) is a fully threaded rod. See figure 2 .

Abstract

The invention discloses an external fixing device with a reduction function. The external fixing device is used in reduction of fracture and external fixing. The external fixing device is composed of guide rails, spicule clips, bending adjusting handles, a hinge, bending adjusting systems, extending and contracting nuts, locking screws and turning handles. The two guide rails are screwed on lateral surfaces of the hinge respectively, the spicule clips are arranged in the guide rails in a penetrating mode respectively, the extending and contracting nuts are screwed on two sides of the spicule clips, the locking nuts are designed on the lateral surfaces of the spicule clips, the bending adjusting handles are screwed at the ends of the hinge, and the bending adjusting systems are installed on the lateral surfaces of the hinge. After spicules are arranged in fracture portions in a penetrating mode and clamped on corresponding portions of the spicule clips, the turning handles are fastened on the corresponding spicules. The external fixing device is used in reduction of fracture and external fixing. The external fixing device finishes traction and compression on fracture sections through spiral force, requires small labor intensity of operators and can finish reduction and fixing of operations in a closure state.

Description

technical field [0001] The invention relates to the field of medical orthopedic instruments. In particular, it relates to an external bone fixation device with a restoration function. Background technique [0002] The treatment of fractures, especially long bone fractures, is divided into two types, internal fixation and external fixation, in order to ensure the alignment of the fracture end and maintain its stability. Regardless of whether internal fixation or external fixation is used, actions such as pulling, shifting, rotating, and compressing the fracture site of the patient are required—commonly known as restoration. The restoration process is time-consuming and laborious, and even requires the joint efforts of two or more doctors to complete it. From time to time, X-ray observations are required. Medical staff and patients must be exposed to X-rays for a long time, and the restoration effect cannot It is very unsatisfactory, and even the affected area has to be cut ...
