Embodiment Construction

[0012] Such as figure 1 As shown, the present invention mainly includes: an external fixator 1 and an electric micro-motion device 2, and the connection method is: the electric micro-motion device 2 is directly arranged on the external fixation frame 1, and the two form a whole.

[0013] The external fixator 1 includes: a semi-cylindrical cover 3, a cylinder with a surface 4, spherical bearings 5 ​​and 6, a half shaft 7, a half shaft sleeve 8, a welded screw sleeve 9, a rotating screw rod 10, and a welded support sleeve 11, which are connected The method is: the semi-cylindrical cover 3 and the faceted cylinder 4 are connected and fixed by the hexagon socket head cap screws, the faceted cylinder 4 at the left end is connected with the half shaft 7 through a spherical bearing 5, and the faceted cylinder 4 at the right end is connected with the half shaft sleeve 8. The space is connected by another spherical bearing 6, one end of the rotating screw 10 is inserted into the slidin...

Abstract

The present invention relates to medical equipment. The externally fixed lightly movable pressurized fracture recovering device includes external fixing frame and electric fine motion arrangement set on the external fixing frame directly to form one integral. The present invention can produce set fine motion in the fracture in settable and adjustable frequency, amplitude and period required for the different stage of fracture treatment. With electric fine motion arrangement, the present invention is small and easy to install, carry about and use.

Description

technical field [0001] The invention relates to a device for fracture rehabilitation, in particular to an external fixation micro-movement compression fracture rehabilitation device, which belongs to the field of medical devices. Background technique [0002] At present, surgeons, in addition to adopting fracture splints and plaster fixation, also use a kind of metal external fixator when treating limb bone fracture patients. Gypsum fixation is likely to cause displacement of the fracture; external fixation is reliable and less likely to cause fracture translocation; in recent years, many experimental studies have confirmed that controlled fretting of the fracture can promote the formation of callus and Calcification accelerates fracture healing. The commonly used induction method is to realize the axial micro-motion of the fracture segment through weight-bearing of the limbs. However, the micro-motion induced by weight-bearing is often affected by different patients' mobil...
