External fixator for knee joint

Abstract

The invention belongs to the technical field of medical appliances, and particularly relates to an external fixator for the knee joint. The fixator comprises a first needle clamp and a second needle clamp, wherein the first needle clamp and the second needle clamp are connected by virtue of a telescopically adjusted rack assembly; the telescopically adjusted rack assembly is provided with a regulating rod device; the second needle clamp can be arranged at one end of the telescopically adjusted rack assembly; the telescopically adjusted rack assembly comprises a first rack plate and a second rack plate; adjusting long holes are formed in the first and second rack plates; and locking devices are arranged in the adjusting long holes. The external fixator is simple and reasonable in structure, and can be used for easily and reasonably fixing the knee joint fracture position by efficient operation to ensure healing of the fracture position, so that the fracture position can be quickly recovered to the original function and appearance, the moving capability of the fixed position can be improved, the convenience and reliability of operation can be guaranteed on the premise of treatment effect guaranteed, and the fracture correction and treatment effect can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a knee joint external fixation bracket. Background technique [0002] Clinical treatment of knee fractures can be divided into non-surgical treatment and surgical treatment. Non-surgical treatment uses reduction splint or plaster for external fixation. The disadvantage is that the fracture is prone to displacement and recovery is slow; surgical treatment uses steel plates. Internal fixation requires a second operation to remove the steel plate, which causes pain to the patient and is prone to symptoms of shortening of the radial bone. At present, the external fixator for knee joint reduction in clinical application is different from the mechanical structure of the knee joint in terms of adjustment function, and its flexibility has great limitations. Many difficulties. Contents of the invention [0003] The object of the present invention is to solve the ab...
