Abstract

The invention belongs to a medical device, i.e. an external fixator for treating bone fracture, in particular to a step motor type pressure feedback multi-mode micromovement external fixator, solving the problem that a healing stage can not be judged, stimulations needed by a fracture site in all healing stages can not be provided comprehensively, and even healing can be inhibited by using the present external fixator for fracture rehabilitation. The external fixator comprises clamping needle fixers; the two clamping needle fixers are respectively connected with a guide post and a guide sleeve; a step motor seat is mounted on the guide post for fixing a step motor controlled by a controller; a sensor seat is mounted on the guide sleeve; a pressure sensor is mounted on the sensor seat; anda ballscrew nut pair is mounted on the pressure sensor. The external fixtor overcomes the defects that the situations of a fracture site in healing stages can not be judged and the mechanical stimulation can not be pertinently regulated by the traditional design, realizes a dynamic pressure stimulation mode, solves the problem of callus damage during the late period of fracture healing by a single displacement stimulation mode, and realizes individualization and digitalization of a therapeutic scheme to obtain a satisfied curative effect.

Description

technical field [0001] The invention belongs to an external fixation device for fracture treatment of medical equipment, and in particular relates to a stepping motor type 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, ...
