Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The core of the present invention is to provide an external fixator, which can well move the bone tissue, and can greatly reduce the surgical incision and trauma to the bone tissue.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] It should be note...

Abstract

The invention discloses an external fixing frame. The external fixing frame comprises a traction plate and a traction needle fixedly connected with the traction plate, and further comprises a thread transmission mechanism which is fixedly connected with the traction needle and drives the traction needle to move in the axial direction. When the external fixing frame is used, a periosteum is stripped under a tibia tuberosity of a patient, a small bone block is cut out, the periosteum on the surface of a tibia is protected, firstly, the traction plate is arranged between the cut tibia bone block and the periosteum on the surface of the tibia, then, the traction needle is connected with the traction plate and the bone block, finally, the thread transmission mechanism drives the traction needle to move in the axial direction of the traction needle. Therefore, by driving the traction needle and the traction plate to move, the periosteum is pulled while the bone block is pulled, so that vasculature neogenesis at a shank part can be promoted, neovasculature can be established, nutrient blood at the shank part can be increased, and then natural healing of a diabetic foot wound surface is promoted.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an external fixator. Background technique [0002] Diabetic foot is a serious complication of diabetic patients. Due to vascular disease of the lower extremities, co-infection and diabetic peripheral neuropathy can lead to chronic foot ulcers, and gradually develop into chronic refractory wounds, and even disability and deformity. [0003] At present, in China, the "tension-stress" law of Ilizarov technology is used to treat diabetic feet through tibial transverse bone transfer technology, pulling the medial tibial bone fragments, promoting the regeneration of blood vessels in the lower extremities, and finally achieving the goal of treating diabetic feet. However, in the prior art, during the lateral tibial bone displacement process, the resected bone fragment of the tibia is relatively large, leading to incision infection and even combined tibial osteomyelitis. The...
