Pressure feedback multi-mode micro external fixture

Abstract

The invention relates to an external fixture for fracture treatment, in particular to a pressure feedback multi-mode micro external fixture, which belongs to a medical instrument The fixture solves the problem that the conventional external fixture for fracture recovery cannot judge the healing stages, nor provide the stimulation for the broken end at each healing stage, but can inhibit the healing. The fixture comprises two clamping pin fixers and a mechanically pressurizing device, wherein the two clamping pin fixers are connected with a broken bone; the mechanically pressurizing device canmake the two clamping pin fixers generate relative displacement; the mechanically pressurizing device is provided with a pressure feedback device; the pressure feedback device is connected with a controller; and the controller is connected with a driver of the mechanically pressurizing device. The fixture overcomes the defect that the conventional design cannot judge the healing condition of the broken end and adjust mechanical stimulation, realizes a dynamic pressure stimulation mode, overcomes the defect that the single displacement stimulation mode can cause callus damage at the later healing stage of fracture, realizes individuation and digitization of the therapeutic scheme and achieves satisfied therapeutic effect easily.

Description

technical field [0001] The invention belongs to an external fixation device for fracture treatment of medical equipment, and in particular relates to a pressure feedback multi-mode micro-motion external fixation frame. Background technique [0002] Usually, for the treatment of limb fractures, internal fixation techniques such as medullary nails, steel plates, and external fixation techniques such as splints, plaster fixation, and metal external fixators can be used. Clinical observations have found that too strong fixation (including internal fixation and external fixation) can lead to slow fracture healing, while unstable fixation can lead to delayed fracture healing or even nonunion. Under the premise of maintaining basic stability, appropriate micro-movement or pressure can promote the healing of fractures. [0003] Micromotion or pressure stimulation is usually applied to the fractured end by means of physical exercise and weight bearing. However, the stimulation of f...
