Triangular telescopic type skeleton recovering external fixing frame

Abstract

The invention discloses a triangular telescopic type skeleton recovering external fixing frame. The triangular telescopic type skeleton recovering external fixing frame comprises a pair of telescopictype fixed ring modules and six detachable connecting rod mechanisms, wherein the telescopic type fixed ring modules are connected through the six detachable connecting rod mechanisms; fixtures for clamping steel needles are fixed on the telescopic type fixed ring modules; and each telescopic type fixed ring module comprises corner sleeving pieces, straight line embedding pieces, fixing bolts andscrewing nuts. According to the triangular telescopic type skeleton recovering external fixing frame disclosed by the invention, the size of each fixed ring can be adjusted in manners of adjusting thepositions of nuts and removing connecting pieces, so that the applicability and the compatibility of the triangular telescopic type skeleton recovering external fixing frame are improved; and the design of detachable electric push rods is provided, firstly, the replaced connecting devices are connected to two ends of two straight line push rods through bolts, the positions of the two end points are not changed, then the electric push rods are detached, and replaced screw rod devices are used for replacement.

Description

technical field [0001] The invention relates to the field of orthopedic correction and rehabilitation, and more specifically, to a triangular telescopic external fixator for bone rehabilitation. Background technique [0002] In the treatment of orthopedic surgery, fixation devices are indispensable. Traditional fixation methods generally use internal fixation with steel plates, and now there are also external fixation methods with less trauma. Commonly used external fixation devices are mainly Ilizarov external fixator and Taylor skeleton. The Ilizarov technique uses multiplanar thin Kirschner wires to penetrate the limb and bone tissue and connect to a ring fixator. Dr. Taylor improved the Ilizarov external fixation system by connecting six telescopic extension rods obliquely to the proximal and distal rings, and they can rotate freely at the connection point. As long as the length of one of the extension rods is adjusted, one ring will Change position relative to another...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to solve the problem that in the existing orthopedic rehabilitation field, a series of fixed rings must be selected according to the patient's condition. The size of the fixed rings is difficult to adjust and the manual adjustment is too slow. Adding an electric push rod is not conducive to surgery. After using the problem, a triangular telescopic bone rehabilitation external fixator is proposed, the size of the fixation frame can be adjusted by adjusting the position of the nut and removing the connector, and the length of the rod can be adjusted by driving the electric push rod. For adjustment, the length can also be adjusted through the screw, and it can be easily disassembled after the motor adjustment is completed
